Utility theory -- Analysis ,Decision-making -- Research - Abstract
A paper on the Analytic Hierarchy Process (AHP) suggested that the AHP is an arbitrary process. However, a discussion is presented to respond to this charge which suggests that the AHP is a practicable theory built on ratio scales, and that the AHP does not need to be watered down to satisfy those researchers who analyze theories based on interval scales. Specifically, it is suggested that just because the AHP doe not follow the axioms and outcomes of utility theory does not mean the AHP is arbitrary.

In this paper we explore the degree to which patents are representative of the magnitude, direction, and impact of the knowledge spilling out of the university by focusing on the Massachusetts Institute of Technology (MIT), and in particular, on the Departments of Mechanical and Electrical Engineering. Drawing on both qualitative and quantitative data, we show that patenting is a minority activity: a majority of the faculty in our sample never patent, and publication rates far outstrip patenting rates. Most faculty members estimate that patents account for less than 10% of the knowledge that transfers from their labs. Our results also suggest that in two important ways patenting is not representative of the patterns of knowledge generation and transfer from MIT: patent volume does not predict publication volume, and those firms that cite MIT papers are in general not the same firms as those that cite MIT patents. However, patent volume is positively correlated with paper citations, suggesting that patent counts may be reasonable measures of research impact. We close by speculating on the implications of our results for the difficult but important question of whether, in this setting, patenting acts as a substitute or a complement to the process of fundamental research., 1. Introduction While there is a widespread belief that publicly funded research conducted at universities has a significant impact on the rate of economic growth, estimating the magnitude and describing [...]

Guldmann's model indicated very small benefits over costs for the optimal decision versus a wide collection of nonoptimal solutions. Savings seem to be about one per cent of costs. It indicated that for stable markets for gas there is little need for extensive decision analysis. An objective analysis is needed to justify rates in a regulated industry. Analysis is also needed to help in exploration decisions. Gas storage will become more important in the future and more analytic methodologys will need to be developed, not fewer.

When do scientists and other innovators organize into collaborative teams, and why do they do so for some projects and not others? At the core of this important organizational choice is, we argue, a trade-off scientists make between the productive efficiency of collaboration and the credit allocation that arises after the completion of collaborative work. In this paper, we explore this trade-off by developing a model to structure our understanding of the factors shaping researcher collaborative choices, in particular the implicit allocation of credit among participants in scientific projects. We then use the annual research activity of 661 faculty scientists at the Massachusetts Institute of Technology over a 31-year period to explore the trade-off between collaboration and reward at the individual faculty level and to infer critical parameters in the collaborative organization of scientific work.

Company business management ,Strategic planning (Business) -- Methods -- Analysis ,Chief executive officers -- Management ,Leadership -- Analysis - Abstract
This paper addresses primarily two questions. First, when (and why) should a company's strategy be developed by its CEO versus by some outside analyst or other insider? Second, how does strategy interact with vision (in the sense of a strong belief about the right course of action)? The paper studies these questions using a functional definition of strategy as "the smallest set of choices to optimally guide other choices." Among other things, the paper shows that strategy formulation by the CEO leads to both better strategy and better execution, and that a strategist's vision may improve execution. In the process, the paper also identifies criteria that make a decision strategic and derives explanations why strategies often reflect the background of the strategist. History: Accepted by Bruno Cassiman, business strategy. Keywords: firm strategy * commitment * leadership * strategy process * strategy execution * group decisions, 1.

Risk aversion -- Methods -- Analysis ,Sex differences (Psychology) -- Analysis ,Business, general ,Business ,Analysis ,Methods - Abstract
This paper reconsiders the wide agreement that females are more risk averse than males. We survey the existing experimental literature, finding that significance and magnitude of gender differences are task specific. We gather data from 54 replications of the Holt and Laury risk elicitation method, involving about 7,000 subjects. Gender differences appear in less than 10% of the studies and are significant but negligible in magnitude once all the data are pooled. Results are confirmed by structural estimations, which also support a constant relative risk aversion representation of preferences. Gender differences correlate with the presence of a safe option and fixed probabilities in the elicitation method. Keywords: gender; risk; survey; meta-analysis History.

Product management -- Research ,Business, general ,Business ,Research - Abstract
Stiving (2000) proposes an interesting model to explain price-endings. His analysis shows that even when customer demand increases at 9-ending price points, certain firms that use high prices to signal quality are more likely to set those prices at round numbers. This comment raises two issues about the model. First, it appears that the original paper imposes a condition that has the effect of eliminating a broad range of legitimate separating equilibria from the analyses. Second, it appears that the original model does not include constraints to ensure that the demand for each market segment will be nonnegative. When these constraints on demand are included, one obtains different aggregate demand curves, which leads to different equilibrium prices. Using the revised model and analysis, we find that 71% of the prices end in 9 and only 12% in 0. This contrasts with only 3% ending in 9 and 58% ending in 0 for the original study. Therefore, 9-endings still prevail even though high prices can be used by firms to signal high quality. (Pricing; Price-Ending; Signaling; Game Theory), 1. Introduction In a recent paper, Stiving (2000) presents an interesting model to predict or explain why many prices end in a 9 or a 0. The paper proposes that [...]

When the simulation department of Management Science was created in 1978 it ushered in an era of significant methodological advances in stochastic simulation. However, the foundation for the field--not just the work that has been published in Management Science--was provided by two papers published long before simulation had its own department in the journal. We will review the seminal papers of Conway, Johnson, and Maxwell (1959) and Conway (1963), and then trace their impact through eight award-winning papers that appeared much later in Management Science. Key words: simulation; experiment design; output analysis; variance reduction; regenerative model, 1. Two Seminal Papers Our objective is to discuss the technique of digital system simulation.

This concludes a two-part commentary on management science and e-business, the theme of this two-part special issue. After reviewing the topical clusters that give organization to both parts, we sketch the papers appearing in this second part from the perspective of two key questions concerning the impact of the emerging digital economy on management science research: What fundamentally new research questions arise, and what kind of research enables progress on them. We then offer summary comments on the second question based on the papers in both parts. The principal conclusions are that, in meeting the challenges posed by the digital economy, management science researchers are (a) making greater use of parts of economics and computer science/information technology, and (b) exploiting the improving productivity advantages of empirical and methodological work in comparison with theoretical work.

Strategic planning (Business) -- Methods ,Business, general ,Business ,Methods - Abstract
What makes a decision strategic? When is strategy most important? This paper formally studies these questions, starting from a (functional) definition of strategy as the smallest set of choices to optimally guide (or force) other choices. The paper shows that this definition coincides with the equilibrium outcome of a "strategy formulation game," in which such strategy endogenously creates a hierarchy among decisions. With respect to what makes a decision strategic and what makes strategy valuable, the paper considers the effect of commitment, reliability, and irreversibility of a decision; the presence of uncertainty (and the type of uncertainty); the number and strength of its interactions and the centrality of a decision; its level and importance; the development of capabilities; and competition. History: Accepted by Bruno Cassiman, business strategy. Keywords: firm strategy * competitive strategy * coordination * capabilities * commitment * leadership * group decisions, 1.

32. Volatility Uncertainty, Time Decay, and Option Bid-Ask Spreads in an Incomplete Market
- Author

Hsieh, PeiLin and Jarrow, Robert
- Abstract
This paper documents the fact that in options markets, the (percentage) implied volatility bid-ask spread increases at an increasing rate as the option's maturity date approaches. To explain this stylized fact, this paper provides a market microstructure model for the bid-ask spread in options markets. We first construct a static equilibrium model to illustrate the aforementioned phenomenon where risk averse and competitive option market makers quote bid and ask prices to minimize their inventory risk in an incomplete market with both directional and volatility risk. We extend this model to multi-periods and show that the same phenomenon occurs there as well. Two new implications are generated: a volatility level effect and a volatility variance effect. These implications are empirically tested, and the empirical results confirm the model's validity. Finally, we document the importance of detrending the maturity effect by showing that the detrended percentage volatility spread explains future jump intensities better than the original percentage volatility spread.

33. Testing by Competitors in Enforcement of Product Standards
- Author

Plambeck, Erica L. and Taylor, Terry A.
- Abstract
Firms have an incentive to test competitors' products to reveal violations of safety and environmental standards, in order to have competitors' products blocked from sale. This paper shows that testing by a regulator crowds out testing by competitors, and can reduce firms' efforts to comply with the product standard. Relying on competitor testing (i.e., having the regulator test only to verify evidence of violations provided by competitors) is most effective in large or concentrated markets in which firms have strong brands and high quality, and for standards that are highly valued by consumers. Under those conditions, firms tend to test competitors' products and exert high compliance effort. Conversely, unless compliance is highly valued by consumers, a firm with low quality does not draw testing from competitors, and so does not comply. Enforcing a product standard through competitor testing encourages entry by such low-quality, noncompliant firms and can reduce quality investment by incumbents. Stripping offending products of labels (such as "Energy Star"), instead of blocking them from the market, eliminates the problem of entry by low-quality, noncompliant firms, but may reduce incumbents' compliance efforts.

Meng, Juanjuan and Weng, Xi
- Subjects
Loss aversion -- Analysis ,Prospect theory -- Analysis ,Business, general ,Business - Abstract
There has been recent debate about whether prospect theory can explain the disposition effect. Using both theory and simulation, this paper shows that prospect theory often predicts the disposition effect when lagged expected final wealth is the reference point under the principle of preferred personal equilibrium, regardless of whether the reference point is updated or not. When initial wealth is the reference point, however, there is often no disposition effect. Models that use a reference point with no lag under the principle of preferred personal equilibrium or that determine the reference point using the principle of disappointment aversion cannot explain why the investor bought a stock in the first place. Reference point adjustment weakens the disposition effect, leads to more aggressive initial stock purchase strategies, and predicts history dependence in stock holding.

Customer relationship management -- Finance ,Customer loyalty -- Methods ,Customer relationship management ,Company financing ,Business, general ,Business - Abstract
In this paper, we propose a diffusion model for a subscription service. The evolution over time of the number of subscribers is governed by a differential equation combining two processes--namely, a customer acquisition process and a customer attrition process. Assuming profit-maximization behavior of the firm, we use dynamic programming to optimize the customer equity and determine optimal customer relationship marketing expenditures. We implement an augmented Kalman filter with continuous state and discrete observations to estimate the model's parameters using market data of two well-known companies in the telecommunications sector. To the best of our knowledge, this is the first paper to model acquisition and retention efforts in the context of a diffusion model. By doing so, we extend the literature on product diffusion to services--that is, beyond its traditional area of durable (and occasionally nondurable) products. By the same token, we contribute to the literature on customer relationship marketing (CRM), where social interactions have been overlooked. Our analytical and numerical results provide a better understanding of the relationships among the optimal customer equity, the customer lifetime value, the prospect lifetime value, and the optimal acquisition and retention spending. Our model and estimation approach give the tools for assessing empirically the role of CRM spending, social interactions, and other factors in the service subscription dynamics. Our main empirical results are as follows: (i) CRM spending and external incentives have indeed a significant effect on acquisition and retention processes; (ii) the impact of CRM is market specific; (iii) compared with optimal levels, both firms underinvest in retention; and (iv) whereas we observe increasing spending in acquisition over time, the derived optimal policy recommends a decreasing level of spending over time.

Risk management -- Methods ,Logistics -- Methods ,Business, general ,Business ,Risk management ,Methods - Abstract
This paper studies the supply management of a primary input, where this input gives rise to multiple products in fixed proportions. My objective is twofold. First, I study fixed proportions technology under demand uncertainty in comparison with the flexible and dedicated technologies. I show that fixed proportions technology has a cost-pooling value over dedicated technology, which is larger than the capacity-pooling value of flexible technology over dedicated technology. I identify the critical role that demand correlation plays with the fixed proportions technology: in contrast to the capacity-pooling value, which decreases in demand correlation, the cost-pooling value increases in demand correlation. Second, focusing on the fixed proportions technology, I study supply management in the presence of contract and spot markets. I investigate how the optimal supply management strategy should respond to changing market uncertainties, and the differences in this response based on the contract type. I find that when the exercise price of the contract is high, a higher contract market dependence is the best response to the increasing demand correlation or spot price variability. However, a lower contract market dependence is the best response to the same when the exercise price is low. Managerially, these results are important because they imply that the supply management strategy adopted as a response to a change in the business environment should differ depending on the contract type. My results have implications about the new product strategy and the procurement contract choice of the processors in the agricultural industries.

Pricing -- Models ,Equilibrium (Economics) -- Models ,Business, general ,Business ,Product price ,Models - Abstract
No-arbitrage models are extremely flexible modelling tools but often lack economic motivation. This paper describes an equilibrium consumption-based CAPM framework based on Epstein-Zin preferences, which produces analytic pricing formulas for stocks and bonds under the assumption that macro growth rates follow affine processes. This allows the construction of equilibrium pricing formulas while maintaining the same flexibility of state dynamics as in no-arbitrage models. In demonstrating the approach, the paper presents a model that incorporates inflation such that asset prices are nominal. The model takes advantage of the possibility of non-Gaussian shocks and model macroeconomic uncertainty as a jump-diffusion process. This leads to endogenous stock market crashes as stock prices drop to reflect a higher expected rate of return in response to sudden increases in risk. The nominal yield curve in this model has a positive slope if expected inflation growth negatively impacts real growth. This model also produces asset prices that are consistent with observed data, including a substantial equity premium at moderate levels of risk aversion.

This paper considers the effect of firms sending advertising messages to consumers based on their past purchase behavior. If past purchase behavior on a product category is positively correlated with a consumer having high preferences in another category, a firm may want to advertise more intensively to those consumers that purchased the former category, if possible. This paper finds that this can lead to lower prices in the initial category if the annoyance of receiving advertising is large, and to higher prices if the annoyance of receiving advertising is not too large, as consumers expect a possible additional surplus from the category affected by behavior-based advertising. If receiving advertising does not yield too much annoyance to consumers, firms end up better off due to both higher prices and the increased demand of better matching of advertising. Behavior-based advertising may also lead firms to sell less in the initial category than without behavior-based advertising, as a way to be able to better target the most valuable consumers. If the consumer annoyance of receiving advertising is large, firms may end up serving only a few consumers initially, as attracting more consumers requires prices that are too low, and the initial consumers are attracted because of the possibility of lower prices in the following period. The paper also investigates the effects of joint behavior-based pricing and advertising, and of different firms benefiting from the purchase information. History: Accepted by Matthew Shum, marketing.

More specifically, markets for new products and/or services are [...], This paper analyzes competing firms' advertising strategies in markets characterized by dynamic market sizes. For new product innovations, a large literature has been developed on the basis of the celebrated Bass diffusion process, which captures what we call market-size dynamics. However, in spite of the significant literature incorporating competitiveness into the Bass model, few if any analytical results have been obtained, especially those with normative implications. On the other hand, important theoretical and empirical insights have recently been obtained using the famous Lanchester warfare model of competition, in which market-share dynamics are governed by advertising activities for mature products whose market sizes are typically fixed or stable. Our paper seeks to address the issue of optimal advertising strategies incorporating both market-share dynamics and market-size dynamics. In doing so, we seek to take advantage of the theoretical and normative insights currently available in the Lanchester formulation for mature products to obtain normative, analytical results on competitive advertising strategies for new product innovations whose markets evolve around the Bass process. We first obtain analytical solutions to the problem at hand and offer theoretical implications for competitive advertising on the Bass diffusion model. The model's parameters are then estimated using a set of data on sales and advertising expenditures of Polaroid Corp. and Eastman Kodak Co. in instant photography during the 1976-1985 period; optimal trajectories for the firms' advertising spending are then calculated, and other marketing and managerial implications of optimal advertising strategies are explored.

Employee incentives -- Analysis - Abstract
1. Introduction This paper examines whether investment differs for firms switching to residual income (RI)-based compensation from earnings versus return on investment (ROI)-based compensation plans. Prior empirical research (Wallace 1997, [...], This paper examines whether 'you get what you pay for' in firms that implement residual income (RI)-based compensation. Specifically, this paper explores differences in investment patterns of firms that implement RI-based compensation plans conditional on whether the firms switched from earnings or return on investment (ROI)-based compensation. I find that the pattern of investment for firms switching to RI from earnings-based compensation is opposite to that of firms switching from ROI-based compensation. Changes in investment within each individual subgroup yield weaker, mixed results. In addition, this paper documents that delivered RI increases in firms that implement RI. My paper contributes to the literature on the investment effects of RI by examining the relevance of a set of arguments that have been made in management accounting textbooks since 1965. These arguments are still found in current textbooks and are commonly taught to students in graduate level managerial accounting classes. The arguments help us to examine a natural experiment in which we can better specify the conditions under which RI use is expected to be associated with changes in investment.

This paper studies the strategy of sharing inventory information for a Arm that sells two vertically differentiated products. The seller has private information on the aggregate inventory level and the inventory composition of two product variants. The seller credibly and discretionarily discloses inventory information to customers either fully or partially, i.e., disclosing the exact inventory of each product variant, the aggregate inventory level, or no information to customers. Customers form expectations of future availability and make rational purchasing decisions accordingly. In the disclosure literature, discretion usually leads to an unraveling result: sellers who learn favorable market information opt to disclose it, making full disclosure the equilibrium. This paper shows that aggregate inventory disclosure, i.e., partial disclosure, can be instead sustained as an ex post equilibrium. We demonstrate that inventory information aggregation arises when there is an ex post desire to reduce supply-demand mismatches in all inventory scenarios. Specifically, when customers' preferred products are more likely to stock out, the seller could entice more incoming consumers who hope that their desired products are in stock by withholding product composition but disclosing the aggregate inventory level. If customers' desired products are sold out, the seller can benefit from upselling or cross-selling customers' less preferred products. Alternatively, when the seller stocks more desired products, aggregate disclosure can dampen the flow of incoming customers and reduce the shortage penalty cost. This result is robust under various settings: risk-averse customers, heterogeneous customers, and horizontally differentiated products. History: Accepted by Serguei Netessine, operations management. Keywords: information aggregation * inventory information disclosure * cross-selling * product variety, 1. Introduction The advent of the Internet and information system technologies has enabled companies to share various kinds of information with customers at a much lower cost, e.g., inventory information [...]

A modest extra computational effort can result in realization of significant savings when nonorthogonal cutting patterns are utilized. Determination of the best way to cut a number of pieces of material from a reel is usually determined under the assumption that each piece has a side parallel to the reel edge. It may be attractive to consider patterns in which some pieces appear in an intermediate, tilted position when the material to be cut is homogeneous.

This paper estimates the elasticity of intertemporal substitution in consumption ([sigma]) by exploiting a natural experiment provided by a change in the Indian banking legislation. The new legislation authorized banks to offer higher interest rates on deposits to citizens above 60 years of age. We find evidence that households exhibit inertia in reoptimization and are sensitive to the timing of the actual change in the interest rate. Households do not respond to the predictable changes in future interest rates induced by the change in the legislation. We incorporate this and estimate the a to be approximately equal to 2.2. History: Accepted by Amit Seru, finance. Keywords: intertemporal substitution in consumption * expected changes in interest rate * inertia, 1. Introduction In this paper, we estimate the elasticity of intertemporal substitution in consumption ([sigma]), a crucial parameter for evaluating standard models of consumption behavior and macroeconomic policy.

This paper provides a tractable continuous-time, constant absolute risk aversion--Gaussian framework to explore how the interactions of fundamental uncertainty, model uncertainty due to a preference for robustness, and state uncertainty due to information-processing constraints (rational inattention) affect strategic consumption--portfolio rules and precautionary savings in the presence of uninsurable labor income. Specifically, after solving the model explicitly, I compute and compare the elasticities of strategic asset allocation and precautionary savings to risk aversion, robustness, and inattention. Furthermore, for plausibly estimated and calibrated model parameters, I quantitatively analyze how the interactions of model uncertainty and state uncertainty affect the optimal share invested in the risky asset and show that they can provide a potential explanation for the observed stockholding behavior of households with different education and income levels.

This paper develops and estimates a structural model of two-sided markets with durable platform intermediaries and affiliated products. It models buyers' purchase decisions of platforms and affiliated products and sellers' decisions of price setting and entry, accounting for the dynamic interaction between the two distinct groups of platform participants. To estimate the proposed model, this paper develops a Bayesian Markov chain Monte Carlo estimation approach that incorporates nonparametric approximation and interpolation methods. The proposed model and estimation method are applied to the 32/64-bit generation of the U.S. video game industry. The results of counterfactual experiments show that the dynamic behavior of platform participants has significant impacts on platform adoption and the affiliated product market, and that a failed platform could have survived if it had priced the two sides properly in a dynamic two- sided market environment.

This paper studies the effects of unemployment benefit schemes on individual productivity. We created employment and unemployment in the field and compared workers' productivity under no unemployment benefits to productivity under two different unemployment schemes. In one scheme, the unemployed received an unconditional monetary transfer. In the other, the monetary transfer was obtained conditional on the unemployed spending some time on an ancillary activity. Our results challenge the standard economic theory prediction that unemployment benefits, especially unconditional compensations, hinder workers' effort. We find that workers employed under the unconditional scheme are more productive than workers under the conditional one, and both schemes make workers more productive than having no unemployment benefit. We discuss two possible explanations for our results based on reciprocity and differential psychological costs of unemployment across unemployment benefit schemes.

We examine the effect of unionization on firm innovation, using a regression discontinuity design that relies on "locally" exogenous variation generated by elections that pass or fail by a small margin of votes. Passing a union election results in an 8.7% (12.5%) decline in patent quantity (quality) three years after the election. A reduction in R&D expenditures, reduced productivity of inventors, and departures of innovative inventors appear to be plausible underlying mechanisms through which unionization impedes firm innovation. In response to unionization, firms move their innovation activities away from states where union elections win. Our paper provides new insights into the real effects of unionization. History: Accepted by Gustavo Manso, finance. Keywords: innovation * labor unions * hold-up * shirking * inventor departures, 1. Introduction In this paper, we study the effect of labor unions on firm innovation. The impact of unions on innovation is of particular interest to policy makers and firm [...]

Accounting -- Technique ,Letting of contracts -- Methods ,Business, general ,Business ,Methods - Abstract
This paper studies the efficiency and distributive effects of three prominent accounting methods in auction settings when bidders' incentives are linked to accounting income. The purchase price method (PP) requires the acquirer to book the acquisition at historical cost, thereby underestimating the asset value by the amount of the acquirer's surplus in the transaction. The exit value method (EV) is downward biased and forces the acquirer to book an accounting loss on the date of acquisition. EV connects otherwise independent valuations inducing a reporting-based winner's curse and can even lead to fire-sale-like values. Relative to PP, EV implies lower asset prices, a decrease (increase) in the surplus of the seller (acquirer), and an increase in the probability that the asset attains its best use when the market is sufficiently competitive. Finally, I examine an alternative method in which the asset is valued at its perceived value-in-use (VU). Under this method, the acquirer bids more aggressively to increase perceived value-in-use, leading to a shift of surplus from the acquirer to the seller. Yet VU is unbiased and always maximizes the probability that the asset attains its best use. History: Accepted by Gerard Cachon, accounting. Keywords: auctions * fair value * fire sale, 1. Introduction This paper studies the efficiency and wealth distribution properties of accounting methods in a bidding setting. Standard economic principles point to three alternative valuation methods. First, the purchase [...]

Managerial models for practice have undergone remarkable growth in the past 50 years. My paper on decision calculus, published in 1970, was both a progress report and a prescription for improvement. This commentary describes why I wrote the paper, my perception of why it has been considered influential, and a brief overview of what has happened since. The overview starts by tracing the trends and ideas of the 1960s into the 1970s. The 1970s blend easily into the era of decision support systems (DSS). Starting late in the decade and still continuing, DSSs have evolved rapidly due to an explosion of data, increased computer power, and advances in modeling methods. I review highlights of this evolution from the point of view of managerial models, giving special emphasis to marketing, since that has been my window on this world. The good news is that more managers than ever are using models. The bad news is that many managers do not even realize they are using models! (But we should ask whether this is really bad.) The commentary concludes with thoughts about the future of managerial models. The selection of my paper as one of the most influential in the first 50 years of Management Science was a significant honor for which I am grateful. I take it as an indication by the members of INFORMS of the importance to our field of the issues addressed. Key words: decision calculus; managerial models; decision support; DSS; marketing models, 1. Why I Wrote the Paper This was a protest paper. The first sentence put the problem on the table: The big problem with management science models is that managers [...]
