The rise and fall of a market leader: Frozen foods in the U.K.

This paper explores the nature of competitive assets that are based on control of part of a market's infrastructure using a case study of the U.K. frozen food market. Following an argument due to Stigler, the thesis of the paper is that such assets are inherently transitory, and that positions of market leadership based on them tend to erode. This argument is consistent with the experiences of Birds Eye during the post-War period.     

USING RANDOMIZED CONTROL DESIGNS IN EVALUATING SOCIAL SECTOR PROGRAMS IN DEVELOPING COUNTRIES

Seven case studies—from Bolivia, Colombia, Indonesia,Mexico, Nicaragua, Taiwan (China), and Turkey—demonstratethe feasibility of conducting rigorous impact evaluations indeveloping countries using randomized control designs. Thisexperience, covering a wide variety of settings and social programs,offers lessons for task managers and policymakers interestedin evaluating social sector investments. The main conclusions are: first, policymakers interested inassessing the effectiveness of a project ought to consider arandomized control design because such evaluations not onlyare feasible but also yield the most robust results. Second,the acute resource constraints common in developing countriesthat often make program rationing unavoidable also present opportunitiesfor adopting randomized control designs. Policymakers and programmanagers need to be alert to the opportunities for buildingrandomized control designs into development programs right fromthe start of the project cycle because they, more than academicresearchers or evaluation experts, are in the best positionto ensure that opportunities for rigorous evaluations are exploited.      

Bid,ask and transaction prices in a specialist market with heterogeneously informed traders

The presence of traders with superior information leads to a positive bid-ask spread even when the specialist is risk-neutral and makes zero expected profits. The resulting transaction prices convey information, and the expectation of the average spread squared times volume is bounded by a number that is independent of insider activity. The serial correlation of transaction price differences is a function of the proportion of the spread due to adverse selection. A bid-ask spread implies a divergence between observed returns and realizable returns. Observed returns are approximately realizable returns plus what the uninformed anticipate losing to the insiders.     

Ethical Issues in Financial Activities

The financial sector likes to call itself a "service industry". As such, its role is to guarantee the fluidity of transactions which are essential to economic activity by ensuring the best possible use of available capital. If finance is a service activity, it is important to specify what services it renders, to whom, in return for what, and for what purpose. In the absence of such clarification, finance may slide out of control and be left at the mercy of mass enthusiasm or hysteria. This document, which is the result of work by people who hold senior positions in Geneva's financial sector or are external observers of the financial world identifies the issues and suggests some avenues for possible solutions.     

Time-consistent linear taxation and redistribution in an overlapping-generations framework

We study time-consistent labour and capital income linear taxationusing an infinite-horizon overlapping-generations model of asmall open economy. Individuals have different productivitiesand the government intervenes for purely redistributive purposes.The study of time-consistent taxation requires the introductionof borrowing restrictions in the economy. We characterize thetime-consistent solution and consider alternative solutionsbased on a simple tax rule. We demonstrate the existence andthe uniqueness of the time-consistent solution using a log-linearutility function. We provide numerical comparisons between time-consistentand time-inconsistent linear taxation: the importance of beingable to make commitment decreases when the differences betweenindividuals increase.     

The Willingness to Pay for Education for Daughters in Contrast to Sons: Evidence from Rural Peru

In most of the developing world the education of women lagsbehind that of men. This could come about from a lack of parentaldesire for educated daughters or from a perception by the parentsthat there is a lower net return to education for girls. Therelation between gender and education in rural Peru is exploredusing data from the 1985–86 Peru Living Standards Survey.A model of educational choice is developed. The estimated demandfunctions are used to assess the impact of user fees on demandand revenues. The empirical evidence indicates that parentsare more willing to pay for reduced travel time to secondaryschool for boys than for girls. However, parents are willingto pay increased fees for girls' schooling sufficient to generateteachers' salaries.     

Earnings management and firm valuation under asymmetric information

This paper seeks to provide an explanation for why corporate officers manage the disclosure of accounting information. We show that earnings management affects firm value when value-maximizing managers and investors are asymmetrically informed. In equilibrium, the strategic management of reported earnings influences investors' assessments of the market values of companies' shares.     

Market Power,Efficiency and the Dispersion of Systematic Risk

A number of studies have used the Capital Asset Pricing Model (CAPM) to integrate product market and financial theories of the firm. We reexamine the relationship between product market structure and systematic risk at the firm and industry level. We show that theory yields no testable implications at the firm level. We show, however, that there is a relationship between the intraindustry dispersion of systematic risk and industry concentration which depends on the causes and consequences of concentration. Estimates of the relationship between the intraindustry variance of and concentration for a 1987 cross-section of U.S. industries suggest that concentration allows larger firms to exercise market power.
