In the context of the digital economy, digital technology is an important driving force to promote green development and achieve the "dual-carbon goal". Taking 1746 Shanghai and Shenzhen A-share enterprises from 2015 to 2022 as research objects, we empirically examine the relationship between government subsidies, digital transformation, and corporate green technology innovation. The study shows that (1) there is an inverted "U"-shaped relationship between government subsidies and corporate green technological innovation, while digital transformation plays a mediating role, and there is a difference between the quality and quantity of digital transformation in promoting green technological innovation. (2) Through the analysis of the moderating effect, it is found that market concentration has an obvious inhibitory effect between enterprise digital transformation and green technology innovation. (3) The study, by classifying the nature of enterprises, shows that the promotion effect of digital transformation on green technology innovation is weaker under heavily polluted enterprises than under non-heavily polluted enterprises, but the promotion interval of the relationship between government subsidies and green technology innovation is larger. Therefore, enterprises should make full use of digital technology to inject new impetus into their innovation activities, and the government should fully consider the appropriate space for enterprises to receive subsidies, make reasonable use of the incentive effect of government subsidies, and smooth the information docking channels for government and enterprise subsidies.

Objective Data Setting and Design Data Sources and Analytic Sample Principal Findings Conclusions To examine the response of community health center (CHC) quality to quality levels at neighboring CHCs in the presence of non‐price competition.A quasi‐experimental study of US community health centers. Outcome variables were indices that measured overall quality of CHC care. Using patient flow data, we constructed CHC‐specific Hirschman–Herfindahl index (HHI) and competitors' composite quality measure. The plausibly exogenous change in characteristics of “competitors' competitors” was exploited to identify the relationship between competition and quality of care, using a generalized two‐stage least square model with instrumental variables.Using the Health Center Program Uniform Data System (2014–2018), linked with American Community Survey and Medical Expenditure Panel Survey, we analyzed 1098 unique federally funded CHCs in 50 states and District of Columbia which had at least one neighboring CHC and had non‐missing data for 2015–2018 (4226 CHC‐years).Most of CHCs served populations in overlapping geographic markets, with median market concentration decreasing during the study period. A one‐percent increase in competitors' quality was associated with a 0.71‐percent increase in an index CHC's composite quality (p < 0.01), consisting of a 0.59‐percent increase in chronic condition control rates (p < 0.01); a 0.68‐percent increase in the screening and assessment rates (p < 0.01); and a 0.78‐percent increase in medication management rates (p < 0.01). The association was stronger at CHCs serving a smaller proportion of uninsured patients. No significant quality reaction was observed at CHCs with a percentage of uninsured patients larger than the 75th percentile. We observed no significant associations between HHI and quality.Increasing competition does not harm quality of care at CHCs. A CHC appears to improve its quality if its competitors improved quality. The beneficial quality effect was less pronounced in CHCs providing a significant proportion of care to uninsured patients, suggesting lack of incentives faced by these CHCs. [ABSTRACT FROM AUTHOR]

Translators are facing worsening working conditions that are compromising their ability to make a living in the language industry. This situation has been attributed to different economic, technological, and professional reasons. An important factor that has not been considered to date which might explain this situation is a possible scenario of market concentration in the language services industry. To assess the validity of this assumption, a dataset on the top 100 language service providers' revenue, market share, relative size, and mergers and acquisition operations for the 2011–2020 period has been compiled and analyzed. The results point to a situation of market concentration and dominance by a few players in the top 100 language services providers segment, while the business landscape for the whole language services industry remains hard to characterize, with only circumstantial data pointing to a possible situation of market concentration and dominance, that would require access to further, more granular data to be determined.

This study explores how firms build organizational resilience (OR) through constructing their corporate social responsibility (CSR) practices. Based on the optimal distinctiveness theory, we propose that a firm may be able to simultaneously conform in scope and differentiate in emphasis in its CSR practices to meet the institutional and strategic needs of CSR, thus building OR. Using data collected from 574 Chinese listed firms during the unique setting of the COVID‐19 pandemic, we provide evidence that CSR scope conformity enhances organizational stability, whereas CSR emphasis differentiation enhances organizational flexibility during a transboundary pandemic period. Furthermore, firm competitive position strengthens the positive relationship between CSR scope conformity and organizational stability. Market concentration strengthens the positive relationship between CSR emphasis differentiation and organizational flexibility. This study contributes to the CSR and organizational resilience literature by highlighting the influence of CSR optimal distinctiveness on OR. [ABSTRACT FROM AUTHOR]

Purpose – This study aims to explore the interplay between market concentration and implicit tax burdens in Brazil, offering a fresh perspective on the conventional belief of perfect competition. Design/methodology/approach – Data was sourced from Brazilian firms on the B3 stock exchange between 2011 and 2021. Multiple linear regression techniques were employed to analyze the relation of explicit tax rates to firms’ pre- and post-tax returns. Findings – Dominant firms in the market tend to bear a lower implicit tax burden and have the capacity to extend tax incentive benefits to shareholders. Research limitations/implications – The findings highlight Brazil’s intricate corporate tax fabric, particularly regarding implicit taxes. They provide a foundation for deeper inquiries into how market dominance, taxation policies, and corporate strategies converge. Practical implications – Regulators and business leaders can harness this knowledge to recalibrate tax strategies and market regulations. Specifically, a closer examination of the dynamics that permit reduced implicit tax implications in monopolized markets is essential for equity. Social implications – Companies with pronounced market concentration can mitigate their implicit tax burdens, potentially offloading them to consumers and suppliers. This points to potential inequities in current tax structures. Originality/value – This research unveils nuanced insights into Brazil’s multifaceted interrelations between corporate influence, taxation strategies, and market forces.

Abstract Background The Brazilian supplementary health market has undergone transformations in recent years due to constant mergers and acquisitions of by large corporations, contributing to the increase in market concentration, especially in the poorest and least developed regions of the country. Thus, given the care it provides and its economic relevance, understanding the fundamentals of these movements, the likely consequences and trends for the health market are relevant, important, and strategic. Objective To understand the general and specific context of Brazilian supplementary health, its scenarios, and trends, with emphasis on the analysis of market concentration and recent mergers and acquisitions. Methodology The research is applied, descriptive and exploratory and uses secondary data from various sources, submitted to quantitative data analysis methods. The data are organized into three groups: historical and regulatory documents; industry data; and market. Results The results show the growing concentration of the market promoted by large publicly traded corporations, the growing relevance of tech startups on the healthcare landscape, the predominant use of the relative valuation model, with implicit multiples for asset pricing and the prevalence of corporate health plans. Conclusion The growing concentration of the system projects a market with fewer options and less competitiveness, since the growth of large operators is evident, in addition to the relevant increase in the number of complaints from users of the system, which signals the growing gap between the expectations of users and the levels of quality care offered. The study also highlights the predominance of corporate health plans, revealing the direct relationship between access to supplementary health services and employability rates. The analysis of M&A operations, in addition to the increase in market concentration, reveals the prevalence of the use of the relative valuation model and implicit multiples for the pricing of traded assets. This denotes the future expectation of wealth generation, at least equivalent to the historical series of the sector, on the part of investors, whose frustration may signal the decreasing attractiveness of resources and M&A operations in the sector in the coming years.

Purpose – This study aims to analyse the effect of competition on retail fuel prices in a small European Union (EU) country with high market concentration. Design/methodology/approach – The researchers use a panel data set to estimate a fuel price equation that includes supply and demand factors as well as time-fixed effects. Findings – The study finds that more competitors in the local market decrease prices, whereas the high market share of oligopoly brands does not condition this effect. Additionally, independent brands set lower prices than wholesalers, and gas stations located near the borders of almost all neighbouring countries are associated with higher prices. Research limitations/implications – The study suggests that Slovenia’s retail fuel market maintains competitive pricing despite high oligopolistic shares because of historical regulatory influences that shaped firm behaviour and pricing strategies, along with geographical and economic factors such as Slovenia’s role as a transit country. External competitive pressures from neighbouring countries and high levels of traffic, combined with the remnants of regulatory structures, help prevent market abuses and keep fuel prices lower than in other EU countries. Practical implications – It also indicates that policy should encourage fiercer competition in the local market by increasing the density of gas stations, especially from independent brands. Originality/value – These findings may be associated with specific country characteristics. This paper introduces unique findings that shed light on the impact of a small market on competition, with a particular focus on highlighting the effect of oligopolistic brands.

I estimate aggregate and industry-specific elasticities of scale and markups for the U.S. economy over the period from 1980 to 2019 using data on publicly traded companies. I apply Olley–Pakes and Ackerberg–Caves–Frazer estimation methods and find that the aggregate elasticity of scale for the U.S. economy is 1.1 and has been rising. The elasticity of scale in turn serves as an input for calculating industry markups. Increasing returns to scale help explain observed increases in markups over the last decades for broad sectors of the economy. My estimate of 1.2 for the aggregate markup is significantly lower than the estimate of 1.6 found in recent literature. The large disparity in markup estimates stems from differences in the treatment of fixed and variable costs and the methodological approach to the calculation of markups. • The U.S. economy has been experiencing increasing returns to scale. • The elasticity of scale is estimated at 1.1 and it has been rising. • I use Olley and Pakes (1996) and Ackerberg et al. (2015) estimation methods. • Increasing returns to scale can explain industry concentration and markups. • The aggregate U.S. markups have increased from 1.03 to 1.17 from 1980 to 2019.

The aim of the paper is to examine the relationship between market concentration and foreign direct investment (FDI) in the Serbian finance sector. Therefore, the banking, financial leasing, and insurance sector data were analyzed from Q4 2007 to Q4 2020. The ARDL approach was used to determine the long and short-term relationship between market concentration and FDI. The results show a significant positive relationship between market concentration and FDI in the long run, while a significant negative relationship in the short run. It means that competition worsens in the long term, while improves in the short term due to FDI because decreases in market concentration mean improvement of competition conditions.

Market concentration is considered a concept that refers to the number of firms in any industry and the distribution of the sizes of these firms. There are two theoretical approaches to the effects of competition in the market on foreign trade. These approaches are the national champion approach and the competitive approach. While both approaches assume that domestic competition is a determinant of the success of industries in global markets, they have different arguments about how competition affects foreign trade. In this study, the effects of the market structure on foreign trade were examined on the industry scale using the panel data analysis method in the context of the Turkish manufacturing industry for the period between 2013 and 2018. In the scope of the contract made with TURKSTAT, the study employed micro-level firm-scale datasets, and the collected manufacturing industry firm data were consolidated at the level of 199 4-digit industries based on NACE Rev.2. According to the results of the static panel data analysis, it was determined that market concentration had positive effects on imports and exports. Furthermore, the economies of scale affected imports and exports negatively, the real effective exchange rate index affected exports negatively, and labor cost affected exports positively. Considering the empirical findings for the Turkish manufacturing industry, it was concluded that SMEs, which had a superior number of firms, were more successful in exports in general compared to larger firms. It is expected that the results of this study will contribute to future studies to be conducted to investigate the effects of competition in markets on global trade. [ABSTRACT FROM AUTHOR]

Market concentration is associated with higher prices. However, previous research has not considered whether the market concentration effect on prices is moderated by seasonality in markets where firms switch from peak demand to low demand periods. This study analyzes market concentration effect on prices and price variability in the hotel industry. Through hedonic price models, the paper analyzes the influence of market concentration on hotel prices and how quality, distance to the city center or seasonality influence hotel prices. A higher market concentration is associated with higher prices. The effect of market concentration on prices is 1.7 times higher in the peak demand season than in the low demand season. Price variability between hotels for a given day in a particular market is partially explained by differences in service quality among hotels in the same city but also by the level of market concentration. We find that higher market concentration reduces price variability, a result consistent with the existence of tacit collusion. [ABSTRACT FROM AUTHOR]

This paper examines the environmental, social, and governance (ESG) requirements for an industry in an n‐oligopolistic model and investigates the relationship between the degree of industry concentration and the degree of ESG requirements. It is shown that the factors influencing the degree of ESG requirements include the number of firms, the elasticity of market demand, and the market concentration ratio. In the case of linear market demand, the degree of requirements is negatively affected by firm number only, regardless of the elasticity of market demand or market concentration ratio. In addition, the degree of ESG requirements is positively (negatively) related to the industry profit/concentration, when market demand is convex (concave). This paper demonstrates that the degree of ESG requirements is sensitive to firm number, market demand, and market concentration ratio and serves as a pragmatic reference for the government.

Our study, using statistical methods, provides empirical evidence to support the hypothesis that in order to get as close as possible to “human scale development”, as proposed by Max-Neef and colleagues in 1986 (English version 1991), we need to get as close as possible to the microeconomic ideal of so-called perfect competition, a situation in which many small and medium-sized enterprises compete with each other, while the GDP growth rate does not seem to be directly related to development. The ideal of “perfect competition” is part of the repertoire of classical economic theory. Few adherents of classical economic theory manage to build a bridge between economic theory and wellbeing when wellbeing is defined in terms of fundamental human needs, as Max-Neef & colleagues have done in their Human Scale Development approach. On the other hand, the adherents of Max Neef’s theory would, at first sight, usually not agree with the assumption, proven in our paper, that competitive markets are a way to get closer to human scale development, i.e. development where people can best satisfy fundamental human needs. Our paper tries to help bring both positions together.

This study examines whether auditor market power is associated with audit quality. Regulators around the world have repeatedly expressed concerns about the high levels of supplier concentration, the limited number of audit suppliers in the audit market, and the potential adverse consequences of their (alleged) market power. Using U.S. data from 2009 to 2017, we examine the effect on audit quality of two competing measures of auditor market power: (a) a "traditional" market concentration measure (Herfindahl index) and (b) a competing measure derived from spatial competition theory (i.e., market share distance from the closest competitor). Following Aobdia, we infer audit quality from two measures of financial reporting quality: (a) the level of absolute abnormal accruals, and (b) the incidence of financial statement restatements. Our results indicate that industry market share distance is positively associated with audit quality, but we do not find an association between market concentration and audit quality. In addition, we find that the positive association between market share distance and audit quality only holds when the incumbent auditor is a market leader, although industry leadership itself is not significantly associated with audit quality. These findings suggest that audit quality is positively affected by a market leader's industry market share dominance over its competitors rather than by industry specialization per se.

Objectives: Optimizing the pharmaceutical industrial structure is the key mission of China’s healthcare reform. From the industrial structure perspective, this study empirically evaluated the impact of China’s national volume-based procurement (NVBP) policy on market concentration in the hospital-end drug market. Methods: This study used drug procurement data of China’s public medical institutions which obtained from the national database. A quasi-natural experiment was designed involving eleven pairs of matched treatment-control region combinations, with NVBP policy as the intervention measure. The market was defined by drug name (molecular boundary) and city/province (geographical boundary). Market changes were measured from three dimensions: the number of enterprises and products, market share, and Herfindahl-Hirschman index (HHI). Dual comparison approach and difference-in-difference (DID) method with fixed effect model were applied to quantify policy impacts. Results: The number of enterprises and products decreased by 18 and 83 in pilot regions after NVBP policy, far more than the decreases in control regions (6 and 21). The accumulative market share of 15 bid-winning enterprises increased by 53.67% in volume and 18.79% in value, among which the increment of enterprises with low baseline market share was more prominent (66.64% and 36.40%). Among three enterprise types, the market share of generic consistency evaluation (GCE) certificated generics significantly increased, GCE uncertificated generics significantly decreased, and originators slightly decreased. DID models indicated significantly positive impact of NVBP policy on market concentration, with HHI-volume and HHI-value increasing by 49.33% (β = 0.401, p < 0.01) and 21.05% (β = 0.191, p < 0.01). Conclusion: The implementation of NVBP promoted the intensive drug circulation and supply of Chinese public hospitals, intensifying the exit of GCE uncertificated generics from the hospital-end market. NVBP combined with GCE standards significantly improved market concentration, which brought a positive signal of pharmaceutical industrial structure optimization in China. In the future context of normalized and institutionalized NVBP, the balance should be further sought between low drug prices and reliable hospital drug supply, sustainable industry development.

Using a sample of 7,919 banks from 30 OECD countries over 1995–2019, we examine the impact of low interest rates on banks' net interest margins. Our results confirm a positive relationship between interest rates and interest margins, which is stronger in a low interest rate environment. In more concentrated markets, however, interest margins are less sensitive to the level of interest rates, as interest rate sensitivities of income and expense margins match. But our results also suggest that the effect of market concentration on the link between interest rates and interest margins is weaker when interest rates approach zero. [ABSTRACT FROM AUTHOR]

In recent years, as China's economy has grown at a rapid pace and social welfare has increased dramatically, environmental issues have become increasingly prominent. Whether companies undertaking digital transformation will improve the environmental performance has drawn the focus of scholars. For this reason, this paper uses the microfirm data of China's manufacturing industry from 2011 to 2020 to explore the relationship between corporate digital transformation (CDT), market competition, and environmental performance, as well as its external mechanism. The study has found that in the analysis of environmental performance measured by firms' pollution emissions, the improvement of the level of CDT shows a nonlinear trajectory in its impact on environmental performance. With a highly centralized market environment, the impact of CDT on environmental performance is further diminished. By analyzing the variability of the degree of market competition, the CDT can promote the environmental performance by enhancing market competition (reducing market concentration). In addition, from the perspective of source reduction, the CDT also advances the environmental performance. The research conclusions contribute to the study of environmental performance, which can guide the transformation from end‐of‐pipe pollutant emissions to source reduction to promote the sustainable development of enterprises.

Purpose: Academic research has intensively analyzed the relationship between market concentration or market power and banking stability but provides ambiguous results, which are summarized under the concentration-stability/fragility view. We provide empirical evidence that the mixed results are due to the difficulty of identifying reliable variables to measure concentration and market power. Design/methodology/approach: Using data from 3,943 banks operating in the European Union (EU)-15 between 2013 and 2020, we employ linear regression models on panel data. Banking market concentration is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated by the product-specific Lerner Indices for the loan and deposit market, respectively. Findings: Our analysis reveals a significantly stability-decreasing impact of market concentration (HHI) and a significantly stability-increasing effect of market power (Lerner Indices). In addition, we provide evidence for a weak (or even absent) empirical relationship between the (non)structural measures, challenging the validity of the structure-conduct-performance (SCP) paradigm. Our baseline findings remain robust, especially when controlling for a likely reverse causality. Originality/value: Our results suggest that the HHI may reflect other factors beyond market power that influence banking stability. Thus, banking supervisors and competition authorities should investigate market concentration and market power simultaneously while considering their joint impact on banking stability.

This study aims to present research results on the competition on the bread market of Kyiv and its region to identify strategic development directions, considering changes in consumer needs during economic and geopolitical turbulence. The research methods included: socio-economic analysis to assess the impact of turbulence on the bread market in Kyiv and its region; statistical analysis to quantify and compare market parameters with those in Ukraine; index method to evaluate market concentration; SLEPT analysis to examine external factors affecting the market during turbulence; and other methods. The pandemic transformed the bread market due to rising prices, increased demand, and disrupted logistics. During the war, infrastructure destruction, grain theft, and consumer migration led to a decline in bakery production, changes in value chains focusing on security, and rising selling prices. The issues like delayed payments and a shift to online sales have emerged. Regionalization of bread markets increased, with producers concentrated in 1-2 regions, defining local supply and prices. The market shifted from weakly to highly concentrated in 2022, becoming moderately concentrated in 2023. Core players, such as Kyiv BCC LLC and Kyiv Regional Bak Complex LLC, showed resilience, while income differentiation remained average. A trend towards organic products, driven by safety concerns, has also been noted. The results of this study are relevant to participants of regional bread markets who aim to implement marketing strategies during periods of turbulence. The findings assess the economic situation on the bread market of Kyiv and its region, highlighting potential strategic development directions for producers during wartime based on marketing and logistics principles.

This article examines sport/discipline-specific market concentrations in the context of the eight Summer Olympic Games held between 1992 and 2020. Three market concentration-related debates underpin this study: (1) the number of competing firms; (2) market size; and (3) time. A normalized version of the Herfindahl-Hirschman Index (HHIN) is calculated for gold medal and medal concentrations for all 42 sports/disciplines. The analyses included panel data models and Pearson correlations. The main findings are that (1) market concentrations for (gold) medals within most sport/disciplines have not significantly declined over time; and (2) neither an increased number of competing National Olympic Committees (NOCs) nor increased market size is likely to have impacted market concentration within a sport/discipline. The findings advance the understanding of market concentration trends and have implications for elite sport practitioners including the International Olympic Committee (IOC) and International Federations (IFs) in terms of an evaluation of existing measures introduced to promote competitive balance, and NOCs in terms of resource distribution among sports/disciplines and prioritization strategies.

The air transport market in Africa is regulated and viable for designated carriers. Although there are some sub-regional liberalizations, airlines primarily compete based on the specifications of bilateral air service agreements. However, this competitive landscape has not been thoroughly investigated. This study examines market concentration in the African aviation industry and explores its impact on the output of African airlines. The competition was measured at the airport level using the Herfindahl-Hirschman index. Panel data were drawn from 54 countries, 339 airports, and 221 airline groups for the period 2015–2019. Kernel density estimation shows that the region’s market for air transport services is fragmented, with many small airlines. Strong competition is more prevalent at larger hub airports, airports near tourist destinations, and major airports far from larger African hubs, while markets tend to be concentrated where dominant and protected flag carriers operate. Competition is also low or limited at smaller airports offering limited flights. The results of panel regression analysis reveal a nonlinear relationship between market concentration and airline output, as strong competition may limit airlines’ output, and high concentration may promote a dominant airline or alliance that may hinder other airlines from entering or remaining in the market.

First paragraph: The government and the press in the United States tend to define corruption narrowly as the misbehavior of individual politicians. They turn a blind eye to systematic corruption such as, for example, the wealthiest people and corporations using campaign contributions to buy political influence. A politician who takes a cash bribe in exchange for a political favor might be deemed corrupt. In contrast, a politician who derails a piece of legislation after receiving a large campaign con­tribution is operating within the limits of the U.S. campaign laws and is, therefore, not deemed corrupt. . . .

Background: Socio-demographic changes increase the need for long-term elderly care. Consequently, providing formal institutional service in elderly care homes is an interesting opportunity for entrepreneurs. However, the entry strategy decision is influenced by numerous external variables. Purpose: The main goal is to answer what determines market concentration as one of the most important market entry determinants. Study design/methodology/approach: A linear regression model has been formed and tested on the Croatian elderly care home market, observed on a county level, using data for 2021. Further, a cluster analysis, as a decision-support tool, has been made to assess market characteristics that are more likely to attract new entrants to the elderly care home market. Findings/conclusions: Results indicate that demand for long-term care services plays a significant role, and the market with more elderly will attract more competitors. When the level of GDP per capita and the unemployment rate are observed together, markets with stronger economies tend to attract entrepreneurs. In other words, it is more likely that someone will open an elderly care home in a densely populated county with individuals that can afford formal institutional long-term care for themselves or family members. Limitations/future research: The shortcomings are mainly related to the lack of data on prices and quality measures. Further, information on the number of beds in each elderly care home would enable an alternative calculation of the Herfindahl-Hirschman index, while data on service prices and structure of employees as a proxy for quality (medical and non-medical staff) would enable a more reliable comparative analysis of obtained results. Future studies on this subject include variables related to the portion of unemployed females in the market since female family members more often provide informal care, and at the same time, they are more likely to be employed in formal long-term care institutions.

In the context of the digital economy, digital technology is an important driving force to promote green development and achieve the “dual-carbon goal”. Taking 1746 Shanghai and Shenzhen A-share enterprises from 2015 to 2022 as research objects, we empirically examine the relationship between government subsidies, digital transformation, and corporate green technology innovation. The study shows that (1) there is an inverted “U”-shaped relationship between government subsidies and corporate green technological innovation, while digital transformation plays a mediating role, and there is a difference between the quality and quantity of digital transformation in promoting green technological innovation. (2) Through the analysis of the moderating effect, it is found that market concentration has an obvious inhibitory effect between enterprise digital transformation and green technology innovation. (3) The study, by classifying the nature of enterprises, shows that the promotion effect of digital transformation on green technology innovation is weaker under heavily polluted enterprises than under non-heavily polluted enterprises, but the promotion interval of the relationship between government subsidies and green technology innovation is larger. Therefore, enterprises should make full use of digital technology to inject new impetus into their innovation activities, and the government should fully consider the appropriate space for enterprises to receive subsidies, make reasonable use of the incentive effect of government subsidies, and smooth the information docking channels for government and enterprise subsidies.

This present research is an effort to link market concentration with market performance measured through total factor productivity (TFP). Using regression analysis for a cross-section of industries in India, we determine the market concentration in selected agri-based and hi-tech sectors and analyse its effect on TFP. Earlier international literature on a linkage between market structure and market performance has mixed results. Some researchers support that high market concentration results in high productivity, while other researchers provide evidence that the above relation is not true. To examine this in detail, this paper investigates the impact of market concentration on TFP, and then makes a comparative analysis of selected agri-based (food products #10: and tobacco and tobacco products #12) and hi-tech sectors (motor vehicles, trailers and semi-trailers #29; chemicals & chemical products #20); in India, with the data covering the period 2006–2017. The results shed light on heterogeneities in the role of concentration on TFP. [ABSTRACT FROM AUTHOR]

Practice consolidation by vertical and horizontal integration is a growing trend in surgery. Practice consolidation has not been previously examined in vascular surgery. The Medicare Provider Enrollment, Chain, and Ownership System data were used to identify vascular providers and vascular surgery practices in the United States in 2015 and 2020. Practices were categorized as solo (1 surgeon), small (2), medium (3-5), and large (≥6). The number of providers and the number of practices in each size group were determined. The Hirfendahl-Hirshman index (HHI), a measure of market consolidation, was calculated. Provider count, practice size, and HHI were additionally analyzed by urban and rural regions. All values were calculated for each time point and compared. Vascular providers increased in number from 2929 to 3154 (7.7%) from 2015 to 2020. The number of practices decreased from 1351 to 1090 (19.3%). The number of large practices increased by 49.4%; the number of small or solo practices decreased by 42.1%. The mean HHI increased from 0.486 in 2015 to 0.498 in 2020. Both urban and rural regions had a decrease in solo practices (43.3% and 2.3%, respectively) and an increase in HHI (from 0.499 to 0.509 and 0.793 to 0.818, respectively). All changes were statistically significant. From 2015 to 2020, there is a trend toward vascular providers working in larger practice groups and a corresponding increase in measures of market consolidation. [ABSTRACT FROM AUTHOR]

The existing empirical literature on export promotion policies is almost exclusively focused on their effects for domestic exporters. This paper contributes to this research by empirically examining the effects of export incentives for third-country exports. Using novel CEPR Global Trade Alert data, the study investigates the impact of Brazilian, Indian and Chinese export incentives on exports of OECD and emerging countries. The findings confirm the existence of negative third-country effects of export incentives and demonstrate that these effects are expectedly larger for foreign exporters who exhibit higher similarity in geography of export with subsidized exporters. These results further point to the importance of destination diversification in export strategies. Following strategic trade theory, the study further examines the moderating effect of industries' proclivity to imperfect competition for third-country effects of export incentives. Whereas Chinese export incentives, as predicted by strategic trade theory, cause largest negative effects in industries with higher proclivity to imperfect competition, Brazilian and Indian export incentives, contrarily, cause larger negative third-country effects in industries with lower proclivity to imperfect competition.
