Ramsey pricing and competition: The consequences of myopic regulation

This paper addresses the welfare consequences of applying the Ramsey rule when the regulated firm is not a monopolist in all of its markets. The partially regulated optimum and the outcome of myopic regulation, the Short-Sighted Ramsey Equilibrium (SSRE), are examined in a differentiated duopoly model. In the optimum, the markup of competitive substitute goods is relatively high. In the SSRE, the regulator is likely to set the price of competitive substitute goods lower than optimal, and complementary goods higher than optimal. Strategic reactions by a competitor may reverse the result.I thank Kenneth Train, Michael Crew (the editor), seminar participants at the University of California, Berkeley, and an anonymous referee for comments and suggestions.

Global apparel production and sweatshop labour: can raising retail prices finance living wages?

This paper provides some empirical evidence on issues raisedby the global anti-sweatshop movement. We first consider therelationship between wage and employment growth, finding noconsistent trade-off between them. We then measure the shareof labour costs in the production of garments in the US andMexico. We find that the retail price increases necessary toabsorb the costs of raising wages substantially are small, wellwithin the range of price increases that polls suggest US consumersare willing to pay. We close by considering some implicationsof these results.     

Reward design and CEO succession in the UK

Previous research has shown that top executives often rise to the peak of their organizations after a long-term employment relationship, and that internal promotion to the top is reflected in enhanced baseline salaries. Using data from a representative sample of UK companies, the links between the fixed and variable elements of the Chief Executive Officer's compensation package are examined and whether the appointment has been promoted internally or recruited from outside of the company. From this analysis, it is concluded that the positive impact on basic pay of elevation to the top job from within the company is not present in total compensation or the structure of pay. It also emerges that although tenure does not significantly impact on the structure of pay, it does alter total reward through its impact on the value of options granted: longer company tenure reduces both the award of share options and the total value of the remuneration package; job tenure, on the other hand, raises the executive's reward primarily through its positive impact on baseline salary. Though share ownership reduces the performance sensitivity of earnings, increases in baseline salary are reflected in greater exposure to the use of share options.     

Niche Entry as a Route to Mainstream Innovation: Learning from the Phosphoric Acid Fuel Cell in Stationary Power

The paper charts the efforts to establish a successful niche position for the phosphoric acid fuel cell (PAFC) in stationary power generation, as a precursor to wider technological system and regime change. Market entry depends on matching price/performance characteristics to a niche, and improving performance through increasing returns, the most important and immediate of which are ‘learning effects’. The paper identifies five types of learning effect: (i) migrating the technology to other niches and into the mainstream; (ii) opening the way for other technologies that may have greater scope for migration; (iii) transferring learning within the pioneering company to other technologies or products; (iv) transferring experience to others in the industry; and (v) enabling users to learn. Although PAFC may be perceived as a failure in some respects, a wider perspective suggests it has made a positive and useful contribution to learning.     

Does Foreign Aid Promote Growth? Exploring the Role of Financial Liberalization

This paper examines the impact of foreign aid on the process of economic development in India by controlling for the degree of financial liberalization. A composite index is constructed using the method of principal component analysis to capture the joint influence of various financial sector policies. The results show that while foreign aid exerts a direct negative influence on output expansion, its indirect effect via financial liberalization is positive. Therefore, an important implication of the findings in this paper is that adequate liberalization in the financial system of the host country is a crucial requirement for effective foreign aid. Our results are robust to a number of control variables and estimation techniques.     

Price-making in a competitive market

An attempt is made to analyze the behavior of a price-maker in a purely competitive market. Assuming the price-maker maximizes expected profit subject to the constraint of satisfying periodic excess demand, we derive characteristics of his optimal prices as they depend on current state variables and then obtain properties of the expectation and variance of the long-run stationary probability distribution of price.     

Rewards and Sanctions and the Provision of Public Goods in One-Shot Settings

A burgeoning literature in experimental studies of the Voluntary Contribution Mechanism focuses on the ability of institutions that allow the monitoring, sanctioning, and/or rewarding of others to facilitate cooperation. In this paper rewards and sanctions are examined in a one-shot VCM setting that so far has been unexplored in the literature. The study finds that while some subjects are willing to reward and sanction others at a personal cost, the opportunity to reward or sanction is ineffective in facilitating cooperation relative to previous experiments in which a repeated game environment is employed. The study also compares behavior in an environment in which the imposition of rewards and sanctions is certain to an environment in which imposition is uncertain. The expected value of the reward or sanction is kept constant across environments to focus simply on the effect of uncertainty about imposition. Uncertainty does not change behavior in a significant way, either in the level of cooperation or the willingness of individuals to impose rewards or sanctions.     

Getting the word out: Enforcement information dissemination and compliance behavior

The question for the tax authority is how individuals become aware of enforcement effort. To be an effective tool in reducing tax evasion taxpayers must be aware of the current audit and penalty regime. We use laboratory experiments to examine the compliance impact of types of information dissemination regarding audit frequency and results. The information includes “official” information disseminated by the tax authority, and “unofficial”, or informal, communications among taxpayers. Our results indicate that the effect of the type of post-audit information is conditional on whether the taxpayer is well informed of the audit rate prior to filing. We find that the tax authority would be served by pre-announcing audit rates credibly and by emphasizing the previous period audit frequency in annual reporting of enforcement effort.
