Optimal R&D Policy and Managerial Delegation Under Vertically Differentiated Duopoly

The paper investigates the optimal research and development (R&D) policy in a vertically differentiated market with managerial delegation. We consider not only discriminatory R&D policy but uniform R&D policy as well. It shows that R&D policy can vary depending on the regulator's objective: social welfare, consumer surplus or producer surplus; however, the outcomes are invariant to the nature of market competition. Undoubtedly, the relative‐performance contract plays a crucial role for elaborating policy effects. The government prefers discriminatory R&D policy to uniform policy under a consumer‐oriented objective. On the contrary, under a producer‐oriented objective, the government would prefer to choose uniform R&D policy rather than discriminatory policy.     

Sectoral Effects of Monetary Policy: The Evidence from Publicly Traded Firms

This article examines the impact of monetary policy on net sales of publicly traded firms in various sectors of the U.S. economy. We find that monetary policy has a heterogeneous effect on firms in different industries, with the strongest effect on firms in Retail and Wholesaling. Balance sheet characteristics, especially size, influence the impact of policy. Larger firms in several industries are able to mitigate the effect of policy. We find mixed results for firms' working capital, short‐term debt ratio, and leverage ratio with respect to the operation of the credit channel of monetary transmission mechanism.     

Bounds for best response functions in binary games

This paper studies the identification of best response functions in binary games without making strong parametric assumptions about the payoffs. The best response function gives the utility maximizing response to a decision of the other players. This is analogous to the response function in the treatment-response literature, taking the decision of the other players as the treatment, except that the best response function has additional structure implied by the associated utility maximization problem. Further, the relationship between the data and the best response function is not the same as the relationship between the data and the response function in the treatment-response literature. We focus especially on the case of a complete information entry game with two firms. We also discuss the case of an entry game with many firms, non-entry games, and incomplete information. Our analysis of the entry game is based on the observation of realized entry decisions, which we then link to the best response functions under various assumptions including those concerning the level of rationality of the firms, including the assumption of Nash equilibrium play, the symmetry of the payoffs between firms, and whether mixed strategies are admitted.     

PRICE ELASTICITIES AND PRICING POWER IN EMERGING MARKETS: THE CASE OF PETROCHEMICAL‐DERIVED PLASTICS IN SOUTH AFRICA1

This paper examines whether there necessarily exists a conflict between allocative and productive efficiency in small open economy markets. That productive efficiency favours market concentration is not in dispute, and the sole question we face is whether allocative efficiency suffers under high market concentration. We proceed theoretically and econometrically. We find that the conflict between productive and allocative efficiency is not necessarily as stringent as the international competition policy literature suggests should be the case. In particular, we note that the strategic interaction between the large domestic producer and its competitors makes feasible a range of alternative price elasticities of demand, and empirically that all price elasticities of demand are less than or equal to unity. Nevertheless, the impact of market structure is such as to render feasible a wide range of possible levels of pricing power.     

Certainty of Punishment versus Severity of Punishment: An Experimental Investigation

Compliance with laws and regulations depends on the expected penalty facing violators. The expected penalty depends on both the probability of punishment and the severity of the punishment if caught. A key question in the economics of crime literature is whether increasing the probability of punishment is a more effective deterrent than increasing the severity of punishment. This article uses laboratory experiments to investigate this issue and finds that increasing the severity of punishment is a more effective deterrent than an equivalent increase in the probability of punishment. This result contrasts with the findings of the empirical crime literature.     

中资银行引进境外战略投资者效应的案例研究

在中资银行战略引资步伐加快、外资话语权逐步提升的情况下,本文通过对美国新桥投资集团控股深圳发展银行案例的分析,对外资话语权的提升与中资银行的经营绩效之间的关系进行了探讨。研究发现,外资话语权的提升与中资银行的盈利能力和经营效率之间不存在明显的正相关关系,而外资充分的话语权有助于中资银行防范与化解信贷风险和增强抵御风险能力以及提高业务发展能力;另一方面,外资话语权的提升却与中资银行的业务创新能力呈现负相关的关系。在此基础上,本文提出了有关战略引资的建议。     

Commercial software,adware, and consumer privacy

I study the choice between selling new software commercially and bundling it with ads and distributing it for free as adware. Adware allows advertisers to send targeted information to consumers which improves their purchasing decisions, but also entails a loss of privacy. I show that adware is more profitable when the perceived quality of the software is relatively low, when tracking technology improves, when consumers benefit more from information on consumer products and are less likely to receive it from external sources. I also show that improvements in the technology of display ads will lead to less violation of privacy and will benefit consumers, that depending on the software's quality, there are either too many or too few display ads in equilibrium, and that from a social perspective, adware dominates commercial software.     

Firm Efficiency in Cambodia's Garment Industry on the Eve of the Multi‐Fiber Arrangement Termination

Applying a frontier analysis to 2004 firm‐level data, the present paper investigates firm efficiency and its determinants for Cambodia's garment industry. The study finds that firm experience and remuneration are crucial for improving scale efficiency and overall technical efficiency, while effective use of capital and adequate labor‐skill development are important for enhancing a firm's technical capabilities. Foreign‐owned enterprises with a relatively larger share of foreign labor outperform local firms. However, the present study does not reveal evidence of any advantages of a cluster‐type concentration in Phnom Penh and export markets, nor of any positive impacts of product specialization. The findings imply a need to support skill development for workers and local managers at the middle management level, and to streamline foreign direct investment measures to attract greater numbers of efficient foreign enterprises, so as to promote the development of the garment industry as a whole.     

The Entry‐Deterring Effects of Inflexible Regulation

This paper investigates the signalling role of tax policy in promoting, or hindering, the ability of a monopolist to practise entry deterrence. We show that environmental policy can facilitate the incumbent firm's concealment of information from potential entrants, thus deterring entry, and yet entail welfare improvements. Furthermore, we demonstrate that entry deterrence is more likely to arise when environmental regulation cannot be rapidly revised across time if market conditions change (inflexible regimes) than when regulatory agencies can adjust environmental policy over time.     

Price effects of multimarket contact among movie chains in small US metropolitan areas

Movie theater chains are ubiquitous in major metropolitan areas of the US, with generally two or more of these large chains present. However in smaller metropolitan areas, we see far more variation in the role of these chains. This allows for an opportunity to see whether multimarket contact (MMC) among these firms has an impact on movie pricing in these smaller markets. In this paper, data on movie pricing, market structure, and income and population characteristics are obtained for 79 small metropolitan areas–those with under 250,000 people–which are not part of larger “consolidated” metropolitan areas. A crude measure of MMC is found to indeed be related to price increases in the smallest of these markets.
