This paper introduces an oligopoly model that includes three actors: a cartel (comprising two or more firms that operate like one merged company), a group of competing fringe firms, and a welfare maximizing antitrust authority. The cartel is the Stackelberg quantity leader and the fringe firms are in Cournot competition with respect to the residual demand. The cartel is internally stable if none of its member firms finds it profitable to become a fringe firm. The antitrust authority can destabilize the cartel in the sense of making the cartel internally instable. To this end, the antitrust authority has three policy instruments at its disposal: its own effort, a fine for detected cartels, and a leniency program for cartel members that cooperate with the authority. Taking into account that the use of these instruments is not costless for society, a unique optimal antitrust policy is derived. The analysis reveals that both, the optimal force and mix of the antitrust authority’s policy depend on market characteristics such as the efficiency of the authority’s operations, the public respect for the rule of law, the ethical standards of the firms’ managers, the market volume, and the number of firms operating on the market.

Residential electricity competition is under investigation in a number of U.S. states due to alleged market imperfections including consumer behavior that is supposedly inconsistent with rational, economic decision-making. In this paper, I examine these issues and use a panel data of distribution utilities in Illinois during the period 2011–2017 to estimate demand models for regulated and competitive electricity services. I find that residential electricity consumers in Illinois are acting in a manner consistent with standard consumer behavior theory, with price elasticity of demand estimates that are generally in line with those in the literature, ranging between − 0.40 and − 0.60. Importantly, I find evidence that customers served by competitive suppliers are sensitive to the regulated default service price. Specifically, I find that a 1% decrease in the regulated default service price will lead to approximately 0.5% of customers served by competitive suppliers switching to the regulated default service. These findings call into question some of the underpinnings of policymakers’ critique of residential electricity competition.

This paper analyzes the effect of command-and-control regulation on firms’ incentives for pollution abatement, market structure, and social welfare. We consider a regulation under which firms are not allowed to produce if they were found in noncompliance with the preset emissions standard during the government’s imperfect inspection. In the case of the ex ante monopoly, a loose standard coupled with an intensive inspection effectively induces perfect compliance. In the case of the ex ante duopoly, the intensified inspection directly creates market entry barriers, but it also induces firms to increase abatement investments for better environmental compliance, which indirectly promotes market competition. Moreover, a firm invests more in pollution abatement if it is initially cleaner or more production-efficient than its rival, or if it has fewer potential rival. We also find that regulatory tightening may harm social welfare by reducing the probability of entry, and social welfare may be higher under monopoly than under duopoly when government inspection is sufficiently intensive.

We theoretically and empirically study the effect of variation in regulatory review time on firms’ choices between radical and incremental innovations. We differentiate between entry into new segments (the extensive margin) and increasing the number of innovations in a given sector (the intensive margin). Our theoretical investigation indicates additional entry into medical device segments as a result of shorter application review times. It also predicts firm-level substitution effect, suggesting firms shift their R&D to innovation applications with relatively shorter review times. To test the theoretical predictions, we utilize a unique data set from the U.S. Food and Drug Administration that contains all product market approvals in the high-risk medical device market for the 1978–2007 period. The empirical results generally support our theoretical predictions. However, the results also show that firms are more responsive to changes in the review time for incremental applications compared to radical ones. Refereed/Peer-reviewed

In Europe, gas market mergers aim at reducing restrictions on gas wholesale markets. Market mergers also allow network users to book transport capacity at different gas transmission system operators (TSOs), which may give rise to inter-TSO competition. Our theoretical analysis reveals the incentive for TSOs, operating under a revenue-cap regulation in merged markets, to charge lower tariffs at borders where different TSOs offer capacity, compared to borders where only one TSO offers capacity. This incentive does not directly result from revenue-cap regulation but is due to efficiency benchmarking. We test this hypothesis by applying a panel data analysis to tariffs charged at German border points between 2015 and 2018. In line with our hypothesis, we find lower tariffs at those border points where network users have a choice between different TSOs. An additional sensitivity analysis differentiating between transit and meshed networks confirms this result. We conclude that German TSOs, operating in merged markets and under a revenue-cap regime with efficiency benchmarking, compete for demand at borders at which different TSOs offer capacity.

We revisit Stigler and Friedland’s (J Law Econ 5:1–16, 1962) seminal paper by examining how competitive generation affects prices, sustainability, and reliability in the electricity industry. Exploiting state and year variation in the introduction of regional transmission organizations (RTOs) that facilitate open access to transmission, we first show that wholesale market deregulation significantly increases the prevalence of independent power producers (IPPs). Using RTO membership as an instrument, we find that IPP entry fails to cut electricity prices paid by consumers. This non-result is also robust to using initial electricity tariffs as an instrument for changes in IPP in a long-difference specification. We provide suggestive evidence that the absence of consumer gain can be attributed to efficiency loss due to mandated divestiture of generation assets or simply higher upstream transaction costs. But, increased prevalence of IPPs is associated with more solar and hydropower, although the use of non-fossil fuel as a whole remains unchanged because less nuclear power is used. More IPPs, however, is also associated with less reliable electricity supply. A review of the origins of electricity deregulation suggests that this tradeoff between environmental sustainability and energy security is not likely to have been the major determinant of the deregulation. Rather than a pro-consumer deregulation, the regulatory change is perhaps more appropriately interpreted as a regulatory capture that benefits IPP entrants and existing energy marketers.

We characterize optimal regulated access prices in mixed oligopoly network industries where a private, profit-maximizing firm competes against a public enterprise after purchasing an essential input (e.g., network access). Optimal access prices often are lower for the private firm than for the public enterprise, and can be particularly low for a relatively efficient private supplier. In contrast to a private, profit-maximizing input supplier, the regulator reduces the access price charged to a private supplier as it becomes more efficient. The optimal access price for a private firm is the same whether it competes against another private firm or a public enterprise.

We examine the role of information transparency in Alberta's wholesale electricity market. Using data on firms' bidding behavior, we analyze whether firms utilize information revealed in near real-time through the Historical Trading Report (HTR), which is released 10 minutes after each hour and contains a complete (de-identified) list of every firms' bids into the wholesale market from the previous hour. We demonstrate that firms are often able to identify the offers of specific rivals by offer patterns adopted by those firms. For one of these firms, these patterns are associated with higher offer prices. This is consistent with allegations by Alberta's Market Surveillance Administrator that firms may be utilizing unique bidding patterns to reveal their identities to their rivals to elevate market prices. We show that certain firms respond to rival offer changes with a lag consistent with responding to information revealed through the HTR, and that they respond differently to different firms, suggesting that they are able to infer identification.

This paper derives the timing equilibrium when a vertically integrated producer (VIP) supplies essential inputs to its retail rival. Such circumstances arise in a variety of industries, often characterized by regulated input prices. The distinguishing feature of markets with an influential VIP is that the VIP is not only a retail competitor but is also concerned about wholesale profits–profits it gleans from its retail rival(s). The VIP’s desire to balance profits across wholesale and retail markets leads to results that challenge conventional thinking about timing equilibria. Notably, under quantity competition, rather than the familiar cut-throat race to be a leader, the timing equilibrium prescribes a natural leader–follower sequencing, with each party in a “win–win” situation relative to simultaneous early play.

Regulation is often portrayed as placing a substantial burden on US businesses and the overall US economy. Moreover, policy options of “cutting red tape” and “reducing federal bureaucracy” are often asserted to be a way to stimulate investment and, through this channel, a way to promote economic growth. This paper examines the relationship between growth in regulatory restrictions in the Code of Federal Regulations and manufacturing investment in the United States over the 1970–2009 period. An industry-level dataset is constructed by mapping the novel industry-specific RegData dataset from the Mercatus Center at George Mason University to the comprehensive industry-specific manufacturing data in the NBER-CES Manufacturing Industry Database. In total, the constructed dataset includes 337 manufacturing industries. This approach yields substantial evidence that increased business regulation is associated with decreased business investment.

In the United States, Regional Transmission Organizations (RTOs) operate the power grid serving nearly 70% of electricity customers and are critical organizations for ensuring reliable system operations and facilitating the integration of new technologies and market participants. RTOs are designed to be stakeholder-driven organizations, with rules and policies crafted through a highly participatory process. While the decisions that RTOs make have implications for industry, society and the environment, their decision processes have not been modeled in any systematic way. In this paper, we develop a modeling framework for the stakeholder process of PJM, an RTO serving thirteen states plus the District of Columbia, adapting some of the seminal literature from political science and political economy on the theory of voting systems. This modeling framework can generate predictions of stakeholder process outcomes, identify strong coalitions among stakeholders and identify shifts in political power in the formulation of RTO market rules. We illustrate this analysis framework using a detailed data set from stakeholder deliberations of capacity market reform in PJM. Our model predicts that the current structure of the stakeholder process in PJM makes the passage of capacity market reforms through the stakeholder process virtually impossible because it creates strong coalitions that would favor or oppose changes to capacity market rules. In the capacity market case, we also identify a small subset of voters that act as swing voters and confirm that political power is shifted to these voters by deviations from otherwise strong coalitions and abstentions from the voting process altogether. Our framework represents the first attempt to model the decision-making behavior of RTOs in any systematic way, and points towards emerging research needs in evaluating the governance structure of RTOs.

We develop a vertical differentiation model to analyze welfare implications of environmental policies in a competitive market with production and consumption heterogeneity. Consumers with heterogeneous preferences choose between non-green and certified green products, while producers with heterogeneous production costs decide whether to engage in green production. In order for green products to be recognized by consumers, producers must join a green club. Key findings are summarized as follows. (i) The number of green producers, environmental standard, and overall welfare under the market solution are all socially sub-optimal. (ii) The introduction of a subsidy policy for greener production and standards is shown to increase social welfare, but is not Pareto optimal. (iii) A dual policy, which combines abatement subsidizes for a greener production standard and a tax charge for green certification, is shown to be the Pareto-optimal outcome.

In this paper, we study whether competition in the airport market and the vertical interactions between upstream airports and downstream airlines influence the airport pricing decisions. Using a panel of the 24 largest UK airports, as well as a refined definition of airports’ market structure, we find that lower concentration in an airport’s catchment area and higher airlines countervailing power are associated to lower aeronautical charges.

This paper explores the ramifications of exclusivity arrangements, e.g., iPhone’s partnership with wireless carriers, for market competition and consumer welfare. Two firms compete in a primary good market, and a monopolistic firm offers a value-adding good. The primary good can be consumed alone, while the value-adding good must be consumed with the primary good. The monopolistic firm forms an exclusivity partnership with one of the primary good providers. Buyers are able to consume the value-adding good only if they patronize the monopolistic firm’s exclusive partner. This practice allows the monopolistic firm to extract surplus from the primary good market. Surprisingly, consumers benefit from the exclusivity arrangement. However, overall social welfare declines, despite improvements to consumer welfare.

In liberalized power systems, generation and transmission services are unbundled, but remain tightly interlinked. Congestion management in the transmission network is of crucial importance for the efficiency of these inter-linkages. Different regulatory designs have been suggested, analyzed and followed, such as uniform zonal pricing with redispatch or nodal pricing. However, the literature has either focused on the short-term efficiency of congestion management or specific issues of timing investments. In contrast, this paper presents a generalized and flexible economic modeling framework based on a decomposed inter-temporal equilibrium model including generation, transmission, as well as their inter-linkages. The model covers short-run operation and long-run investments and hence, allows to analyze short and long-term efficiency of different congestion management designs that vary with respect to the definition of market areas, the regulation and organization of TSOs, the way of managing congestion besides grid expansion, and the type of cross-border capacity allocation. We are able to identify and isolate implicit frictions and sources of inefficiencies in the different regulatory designs, and to provide a comparative analysis including a benchmark against a first-best welfare-optimal result. To demonstrate the applicability of our framework, we calibrate and numerically solve our model for a detailed representation of the Central Western European (CWE) region, consisting of 70 nodes and 174 power lines. Analyzing six different congestion management designs until 2030, we show that compared to the first-best benchmark, i.e., nodal pricing, inefficiencies of up to 4.6% arise. Inefficiencies are mainly driven by the approach of determining cross-border capacities as well as the coordination of transmission system operators’ activities.

This paper compares alternative ways of structuring competition in a railway system: vertical separation (VS) and horizontal separation (HS). We compare each structure in terms of its impact on network quality, consumer surplus and social welfare. To do so, we use a two-stage game under HS and a three-stage game under VS to derive Nash equilibrium network qualities, consumer surplus and social welfare, respectively. We highlight four distinct incentive effects that shape network quality under each structure, and we point out that, on balance, they tend to favor higher network quality under HS. However, intensity of transport service competition under each system also plays a critical role in shaping consumer surplus and social welfare. The best case for HS occurs when there is a moderate amount of price competition between the vertically integrated systems, while the best case for VS occurs when there is intense price competition between transport operators. Using computational analysis, we show that it is more likely that HS dominates VS on all three performance metrics.

The Porter hypothesis asserts that properly designed environmental regulation motivates firms to innovate, which ultimately improves profitability. Specifically, the Porter hypothesis posits that more stringent environmental regulation, i.e., greater regulatory stringency, leads to greater profitability. In contrast, the conventional “costly regulation” hypothesis posits that greater regulatory stringency weakens profitability mostly by driving up abatement costs. This study empirically tests these two hypotheses. Of course, regulatory stringency is difficult to measure. More important, regulatory stringency as codified in legislated acts and promulgated rules does not necessarily reflect regulatory stringency in practice, which we deem as “effective regulatory stringency”. Measurement of “effective regulatory stringency” is even more challenging. With this challenge in mind, we divide “effective regulatory stringency” into its two constituent components—(1) legal requirements and (2) regulatory scrutiny—the latter representing government efforts to ensure compliance with the legal requirements. For our analysis, we examine legal requirements in the form of facility-specific effluent limits and regulatory scrutiny in the form of government monitoring inspections. For our empirical analysis, we analyze the U.S. Clean Water Act under which the U.S. Environmental Protection Agency imposes numeric wastewater discharge limits on permitted facilities and conducts wastewater-related inspections. As its primary contribution, our study separately examines the effects of legal requirements and regulatory scrutiny on firm-level profitability in order to appreciate the influence of “effective regulatory stringency”.

This paper considers a polluting firm, subject to environmental policy, who seeks to deter the entry of potential competitors. We investigate under which conditions firm profits are enhanced by regulation. We show that, contrary to common belief, inefficient firms may support environmental regulation when their production is especially polluting. In addition, we evaluate how this result is affected by the regulator’s prior beliefs accuracy and the environmental damage from pollution.

Price cap regulation (PCR) has experienced widespread adoption in the U.S. telecommunications industry, but not in the electricity sector. We suggest that these disparate experiences may reflect in part the manner in which PCR often is implemented in the U.S., relatively limited opportunity for “regulatory bargains” in the electricity sector, and relatively limited competition in the transmission and distribution components of this sector.

Environmental regulations may erode competition owing to additional costs of compliance. To investigate the impact of such regulations in the Japanese electricity market, we analyze the effects of the environmental quality threshold set for public sector procurement. Using data on electricity procurement auctions from 2005 to 2012, we employ an endogenous switching regression model. We show that the environmental quality threshold lowers the participation of new power suppliers in auctions but does not increase their winning bids as long as competition is maintained. In fact, compliance with the quality threshold has made new power suppliers competitive in green auctions. By contrast, electricity utilities have suffered increased compliance costs since the Great East Japan Earthquake in 2011 owing to the shutdown of nuclear power plants and increased reliance on fossil fuels.

Although government regulations on product warranties are common, few studies have empirically examined their effects on product demand. Using a natural experiment, we examine the effect of a newly introduced government warranty regulation in China’s automobile market on product demand. Exploiting the exogenous variation in warranty coverage caused by the regulation, we apply a difference-in-differences analysis and find that the regulation increases the sales of the affected vehicles. Moreover, we find that (1) the demand effects of the regulation decrease as vehicle quality increases, and that (2) these effects are weaker for luxury brand vehicles and stronger for non-luxury vehicles.

This paper examines an efficient market organization for awarding monopoly franchises to assure investment efficiency and revenue sufficiency under conditions of increasing returns. A two-stage auction design achieves ex ante and ex post efficiency by ensuring that the firm with the best technology will be selected, and after winning, the firm will operate at the least cost and price at the marginal cost. Priority-differentiated subscription service fosters self-revelation of demand functions and facilitates fixed cost recovery. With known demand functions, a linear subscription price schedule based on the beneficiary-pay principle achieves efficient fixed cost recovery. With unknown demand functions, a two-part subscription price menu based on nonlinear Ramsey pricing attains an incentive-compatible, second-best result.

In a time of rapidly increasing global digitalization, providers of communications networks find themselves confronted with huge growth in broadband-intense demand and hence must address the need to expand high-performance fiber optic networks. However, since deployment of fiber access networks is subject to high risk for operators, a core question faced by regulatory institutions is how to optimally design the regulatory framework to incentivize investment. This work employs recent EU27 panel data and examines the role of regulatory policies and competition controlling for relevant supply and demand side factors and the investment dynamics. The results indicate that relevant forms of previous broadband access regulation have a negative impact on investment in new fiber infrastructure. Furthermore, infrastructure-based competition from mobile operators and the replacement effect stemming from the incumbents’ existing infrastructure exert a negative impact on investment incentives. Finally, there is clear evidence of adjustment costs underlying the fiber deployment process.

The presence of state-owned enterprises (SOEs) in an industry where private firms operate poses a concern over fair competition. This paper estimates the improvement in consumer welfare from eliminating the SOE’s privileges awarded by state-ownership and regulation. The empirical framework is based on a random coefficient discrete choice model and yields an economically interpretable welfare measure in a differentiated product market. Utilizing data on the Korean cigarette manufacturing industry that recently underwent privatization and deregulation, the estimated model shows a significant increase in consumer surplus. This improvement is ascribed to firms’ better alignment of product lines with consumer preferences, to expanded consumer choice, and to a limited rise in prices. The results, however, raise a distributional concern as the gains mostly fall on consumers of mid- and high-price brands.

We explain how underinvestment in infrastructure upgrades is aggravated under access regulation with a cost-based access charge. When a cost-based access charge is imposed on an incumbent, the incumbent has a weak incentive to invest in infrastructure upgrades due to insufficient rewards for the investment. Then, the incumbent’s underinvestment induces the overuse of a bypass by an entrant that chooses productively efficient technology, when the degree of spillover is large, the production cost of the bypass is low, and the incumbent’s investment cost is high. The overuse of a bypass decreases the incumbent’s profits, which further reduces the incumbent’s incentive for investment. Thus, the overuse of a bypass generates a vicious cycle of underinvestment in infrastructure upgrades.

The deregulation of zoning restrictions on retailers has been at the forefront of urban policy debates in recent years. Despite the increasing attention, however, we know surprisingly little about how the zoning regulations, which impose a constraint on the supply of land for a particular use, affect retailers in urban areas. This paper examines the effect of the zoning regulations introduced in 1968 in Japan on entry of convenience-store outlets. The act specifies two zoning restrictions for retail outlets. First, the law prohibits building commercial outlets in specified residential and industrial areas (“type 1 zoning”). Second, the law requires a developer to obtain permission from the local government to develop an outlet in specified areas (“type 2 zoning”). To account for the spatial dependence in demand, costs, and zoning regulation status across markets, this paper employs an equilibrium model of store-network choice by multistore firms. Using the cross-sectional data of entry and zoning in Okinawa in 2002, the paper finds hypothetically eliminating the type 1 and type 2 regulations would increase the total number of convenience-store outlets by 10–14 and 2–3 %, respectively. Although the magnitude of the increase in store counts and sales are similar across two national chains in Okinawa, the geographical markets in which each firm increases its outlets after the deregulation differ across these two chains.

This paper examines productivity patterns in price cap regulated utilities around price reviews. We specify a variable cost function that we estimate using alternative specifications of technical change. Results show that the pattern of pure technical change differs within and between regulatory cycles. They also provide evidence that exogenous investment reduces the ratchet-problem, that strategic cost cutting behavior is reduced when regulatory cycles are short and that, absent these two features, industry productivity is consistent with strategic cost cutting behavior.

Fiber deployment of next-generation high-speed broadband networks is considered to be a decisive development for any information-based society, yet investment activities and especially the adoption of fiber-based broadband services take place only very gradually in most countries. This work employs static and dynamic model specifications and identifies the most important determinants of the adoption of fiber-based broadband services with recent panel data from the European Union member states for the years from 2004 to 2012. The results show that the more effective previous broadband access regulation is, the more negative the impact on adoption, while competitive pressure from mobile networks affects adoption in a non-linear manner. Finally, we also find evidence for substantial network effects underlying the adoption process.

Endogenous access pricing (ENAP) is an alternative to the traditional procedure of setting a fixed access price that reflects the regulator’s estimate of the supplier’s average cost of providing access. Under ENAP, the access price reflects the supplier’s actual average cost of providing access, which varies with realized industry output. We show that in addition to eliminating the need to estimate industry output accurately and avoiding a divergence between upstream revenues and costs, ENAP can enhance the incentive of a vertically integrated producer to minimize its upstream operating cost. However, ENAP can sometimes discourage surplus-enhancing investment.

This paper examines the effects of emissions trading on firms’ capacity siting choices in the electric sector, considering three programs that are different by their point-of-regulation: source-, load and first-jurisdictional-deliverer approaches. We model each program by assuming electricity sales are through bilateral contracts, and analyze the solutions properties and economic and emissions implications. We have three central findings in this paper. First, when electricity sales in both directions (i.e., in-state to out-of-state and vice verse) are subject to an emissions cap, three programs will produce identical siting distribution. Second, the emissions leakage in the long-run could be lower than in the short-run case in which capacity expansion is not allowed. This is so because in the long-run power producers may opt for clean technologies in fear of the emission costs under a cap-and-trade program. Third, if compared to pure source-based program in which the import sales are not subject to an emissions cap, more pollution-intensive facilities are expected to build in uncapped states, where the regulation is less stringent. Our findings are therefore consistent with some empirical evidence of pollution haven hypothesis.

Regulators often seek to promote the use of improved, cleaner technology when new investments occur; however, technology mandates are suspected of raising costs and delaying investment. We examine investment choices for electricity generation under a strict emissions rate performance standard requiring the installation of carbon capture and storage (CCS) on fossil-fired plants. We compare the strict standard with a flexible one that imposes a surcharge for emissions in excess of the standard. A third policy allows the surcharge revenue to fund later CCS retrofits. Analytical results indicate that increasing flexibility leads to earlier introduction of CCS, lower aggregate emissions and higher profits. We test this using multi-stage stochastic optimization, with uncertain future natural gas and emissions allowance prices. Under perfect foresight, the analytical predictions hold. With uncertainty, these predictions hold most often but we find outcomes that contradict the theory. In some cases, investments are delayed to enable the decision maker to learn additional information.

Regulating former telecommunications monopolies has often been legally and technically complex. Among other options, incumbent operators were mandated to share, sell or split their infrastructure thus encouraging market entry. Given the importance of broadband technologies, competitive access has become a policy priority. We use data from 167 broadband markets over a period of 11 years. Firm and intra-platform competition on the incumbent’s legacy network (Digital Subscriber Line) accelerate adoption of broadband, whereas competition over different access technologies does not. The duration of the different regulatory effects shows that simpler network changes have a long-lasting yet delayed effect compared to technically demanding ones.

In 1996, the Federal Energy Regulatory Commission sought to “remove impediments to competition in the wholesale bulk power marketplace and to bring more efficient, lower cost power to the Nation’s electricity consumers” through a series of market rules. A product of these rules was the establishment of regional transmission organizations (RTOs) and independent system operators (ISOs) charged with facilitating equal access to the transmission grid for electricity suppliers. Whether these changes in market structure have succeeded in achieving the FERC’s goal to provide “lower cost power to the Nation’s electricity consumers” remains an open question. We utilize a panel data set of the 48 contiguous United States and a treatment effects model in first differences to determine whether there have been changes in delivered electric prices as a result of the establishment of ISOs and RTOs. To avoid the confounding effects of electric restructuring, we have initially estimated the model with the full panel data set, and then again without the states that have restructured their electric markets. By considering only the states that have not restructured their electric markets, we can see whether there have been price effects due to the establishment of RTOs, in the absence of restructuring agreements. We estimate a model of annual changes in electricity prices using 2SLS and show that electricity prices fall approximately 4.9% in the first 2 years of an ISO’s operation and that this result is statistically significant. However, we further show that this result is dependent on the presence of states that restructured their electricity markets and the accompanying rate agreements and temporal subsidies that may have forced prices below their market rates. When these restructured states are removed from the data set the price effects of RTOs become indistinguishable from zero. We conclude that rate agreements are the source of the observed decrease in prices and that RTOs have not had the desired effect on electricity prices.

The main purpose of this study is to analyze structural separation policies, especially vertical (i.e. operation-infrastructure) and horizontal (i.e. passenger-freight service) separation. Using the total cost function of a railway organization, we evaluate whether or not vertical separation and/or horizontal separation can reduce costs. For this analysis, we selected 30 railway organizations in 23 European and East Asian OECD countries over 14 years, from 1994 to 2007. Our findings show that horizontal separation reduces railway cost. As for vertical separation, effects change according to the train density of a railway organization. With lower train density, vertical separation tends to reduce cost, while with higher train density vertical separation increases cost.

In many telecommunications markets incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage over the incumbent, since they are more efficient or operate on innovative technologies. Considering both a supply-side and a demand-side asymmetry, the present model analyzes the effect of two regulatory regimes: An access markup for a low cost network and reciprocal charges below the costs of a high cost network. Both regimes may have adverse effects on subscribers, market shares, and profits. It can be shown that an access markup is not generally beneficial and an access deficit not generally detrimental for the respective networks. However, if providers discriminate between on-net and off-net prices a markup on the entrant's termination cost is generally to its benefit and to the incumbent's detriment.

We show that sabotage may be particularly profitable for a vertically-integrated provider (VIP) when its downstream rival can devote effort to reducing its operating costs. Demand-reducing sabotage limits the return the rival anticipates from its cost management activities, and thereby inhibits those activities. The resulting higher costs for the rival increase the VIP’s profit in settings where sabotage would not be profitable if the rival could not manage its operating costs. To limit sabotage by the VIP, the rival may find it profitable to intentionally diminish its ability to reduce its production costs. The diminished ability can produce Pareto gains.

Economists acknowledge the problems of regulated transmission but have different views on the likely efficiency of merchant transmission. This paper first examines the evidence on alleged market failure and regulatory failure as experienced in practice in Australia, where there have been both regulated and merchant interconnectors. Merchant transmission has generally not exhibited the standard examples of market failure but regulated transmission generally has exhibited the standard examples of regulatory failure. Imperfect information—more specifically, in the form of lack of coordination—has often been a challenge whatever the approach. Experience in Argentina suggests that transactions costs are not a barrier to negotiation and efficient investment determined by users. Policy should seek to improve the regulatory framework and to remove barriers to private initiatives. An important role for regulation is to facilitate coordination between potential providers and users of transmission lines.

Models of firms’ influence over the regulatory agencies that oversee them have traditionally been constrained by several factors, including a lack of direct measures of “influence,” an inability to account for variations in the institutional environment within which firms operate, and a nearly singular focus on industry-level measures of interest group strengths. In this paper, we employ a global database and novel measures to provide a fresh look at the determinants of firms’ influence over regulatory agencies. We find that in addition to traditional industry-level determinants, important country-level institutional and firm-level determinants affect firms’ regulatory agency influence. We also find that regulatory process variations affect firms’ influence over regulators. With these empirical estimates in hand, we generate a Regulatory Influence Index that ranks influence levels of typical firms that operate in each sample country in the dataset, and then discuss the substantial country-level variation in regulatory agency influence that obtains.

The organized wholesale electric power markets in the United States are characterized by structural market power, and would not produce competitive results absent administrative intervention. Market power mitigation is a fundamental and permanent part of the market design for the organized wholesale electricity markets. Market power mitigation is essential to FERC’s policy of relying on competition to regulate electric wholesale power prices, consistent with its mandate under the Federal Power Act. Controversy has arisen about how to ensure that the markets clear on the basis of offers that have been determined to be competitive. Specifically, the issue is what institution and function is best situated to provide the initial critical determination about whether a participant’s offer is competitive. Despite recent clarification of FERC policies on the market monitoring function, the roles of market administrators and market monitors are a potential source of confusion and counterproductive institutional conflict. The FERC should refine and clarify its policy in this area by according exclusive responsibility to institutional, independent market monitors to monitor participants’ conduct and the potential for the exercise of market power through ex ante review of cost-based offers used in market power mitigation, subject to review by FERC.

This paper presents a theory of consumer subscription service, unifying priority service and dynamic pricing within a two-settlement system in ways that foster efficient risk management and competitive electricity markets. Consumer subscription service entails transactions in two time periods: a forward transaction that allows consumers to select service options to hedge financial risks and a spot transaction that allows consumers to secure electricity on demand. The difference between the forward subscription and the actual consumption is settled at spot prices determined in a competitive wholesale electricity market. Priority service offers consumers choices from a menu of reliability-differentiated service options with compensatory insurance for curtailments. Following the principles of revelation and competitive consistency, the priority service menu provides consumers opportunities to choose options that are consistent with their individual preferences and demand characteristics. Combining priority service and dynamic pricing, consumer subscription service is Pareto superior to an undifferentiated service design. Overall, consumer subscription service provides consumers incentives and tools for efficient demand management fostering price-responsive demand in competitive electricity markets. It facilitates an essential linkage between competitive wholesale and retail markets in ways that would enable consumers to be engaged in the process of the industry’s transition toward a smart grid future.

This paper examines the determinants of airport aeronautical charges by employing a unique panel dataset covering sixty-one European airports over an eighteen-year period. We are able to extend the literature on the role of airports as an essential element in transport infrastructure by offering the first analysis of the impact of different regulatory policies and privatization on airport charges in a panel data setting where fixed effects can be employed to mitigate endogeneity concerns. Our main empirical results indicate that aeronautical charges are lower at airports when single-till regulation is employed, when airports are privatized, and—tentatively—when ex post price regulation is applied. Furthermore, hub airports generally set higher aeronautical charges, and it appears that price-cap regulation and the presence of nearby airports do not affect aeronautical charges.

During the course of the first thirty CRRI conferences, we have gained considerable insight about how to design regulatory policy in the presence of developing competition. The insight to date has focused on how to harness competitive forces to motivate incumbent suppliers to serve the best interests of consumers. This paper stresses the importance of considering the incentives of regulators and explores the associated changes in standard recommendations for regulatory policy design in the presence of developing competition.

This paper reports the results of an experiment evaluating three regulatory schemes for network infrastructure, in terms of their ability to generate efficient levels of capacity investment. We compare the performance of (1) price cap regulation, (2) a regulatory holiday for new capacity, and (3) price cap regulation with long term contracts combined with a secondary market. The setting is one in which network users can benefit from acting strategically, and are better informed than the network operator about demand growth. We find that the regulatory holiday creates an incentive to underinvest relative to optimal levels. Long term contracts also fail to improve on single price-cap regulation, and may reduce investment by providing noisier signals about future demand.

Motivated by the movement towards vertical unbundling in Europe this study measures the economies of scope for the U.S. electricity industry based on a multi-stage cost function. The paper analyzes three unbundling options and finds evidence for synergies that may be explained by coordination and risk effects. Separating generation from networks and retail appears to be the most costly alternative with an average cost increase of 19 to 26%. If generation and transmission remain integrated but are separated from distribution and retail, average scope economies amount to 8 to 10%. A split between the transmission level and the remaining supply stages leads to a cost increase of approximately 4%.

Minimum quality standards (MQS) constitute an important regulatory tool that can be used to raise product qualities, to benefit consumers and to increase market participation. One of the main assumptions in the existing literature is that firms must comply with standards. Nevertheless, in many industries, and in particular the service industry, quality observability and enforceability are not perfect. Some low quality firms do not comply with standards. What are the welfare implications of an MQS regulation in such an environment? We develop a price competition model of vertical differentiation that accounts for these empirical observations. Contrary to well-established results in the literature, MQS can increase quality disparity between firms and raise hedonic prices. Some consumers get hurt and market participation decreases.

Greenhouse gas regulation aimed at limiting the carbon emissions from the electric power industry will affect system operations and market outcomes. The impact and the efficacy of the regulatory policy depend on interactions of demand elasticity, transmission network, market structure, and strategic behavior of generators. This paper develops an equilibrium model of an oligopoly electricity market in conjunction with a cap-and-trade policy to study such interactions. We study their potential impacts on market and environmental outcomes which are demonstrated through a small network test case and a reduced WECC 225-bus model with a detailed representation of the California market. The results show that market structure and congestion can have a significant impact on the market performance and the environmental outcomes of the regulation while the interactions of such factors can lead to unintended consequences.

A translog cost function is estimated to examine whether carriers use an efficient combination of inputs in the telecommunications industry. Special attention is given to the role of rate regulation reform in an increasingly competitive business environment. Findings suggest that telecommunications carriers facing price-cap regulation do use an efficient mix of labor and capital. In contrast, the condition for cost minimizing use of inputs is not met for telecommunications carriers facing rate-of-return. The superior factor input use allocation by carriers facing price-cap regulation compared to carriers facing rate-of-return regulation is interpreted as suggesting that incentive regulation plays an important role in promoting efficient use of inputs even in a competitive business environment.

This paper proposes a regulatory mechanism for vertically related industries in which the upstream “bottleneck” segment faces significant returns to scale while other (downstream) segments may be more competitive. In the proposed mechanism, the ownership of the upstream firm is allocated to downstream firms in proportion to their shares of input purchases. This mechanism, while preserving downstream competition, partially internalizes the benefits of exploiting economies of scale resulting from an increase in downstream output. We show that this mechanism is more efficient than a disintegrated market structure in which the upstream natural monopoly bottleneck sets a price equal to average cost.

We analyze the interaction between the incumbent’s incentive to upgrade the quality of its network and the entrant’s incentive to build a bypass network when the regulator sets a two-part access tariff to the incumbent’s network. Under this context, the entrant’s investment in a bypass network is delayed with a higher incumbent’s investment in quality. Moreover, the possibility of investment in a bypass network by the entrant has a positive effect on the incumbent’s incentive to upgrade quality. We show that a regulator cannot achieve the first best with a constant access tariff. If he wants to design an alternative welfare improving access tariff, he should set an access fee increasing (decreasing) in quality if the business-stealing effect of quality upgrades is weak (strong). The analysis suggests that if the entrant’s investment costs are declining or its market share is increasing over time, it is not always optimal to require the incumbent to lease facilities at cost-based prices.
