A production function analysis of English maternity hospitals.

In recent years, a number of attempts have been made to explain the output of hospitals by means of production function analysis and, in this particular study, the authors estimate Cobb-Douglas and log-quadratic functions from data for the 193 English maternity hospitals. Of the various inputs into maternity care, the numbers of beds and nurses appear as the most significant determinants of throughput, although the relative quantities actually employed differ from the “technical” optimum. Returns to scale in the maternity service appear to be, at best, constant. The effects of hospital location and type are also analysed and they suggest the existence of significant disparities in levels of efficiency between different hospitals.     

Employment and child-care choices in Canada and the United States

In this paper we examine employment and child-care choices of two-parent families with young children in the United States and Canada, using a pooled data set based on recent national surveys in each country. We find that the employment and child-care choices of Canadian families are similar to those of U.S. families. Estimates of a model of employment and child-care choices indicate significant effects of child-care subsidies, child-care prices, and wage rates on employment and child-care choices. However, none of these factors helps to explain the differences in employment and child-care choices between the two countries.
Ce mémoire examine le choix de l'emploi et du soin des enfants dans les familles où il y deux parents aux Etats-Unis et au Canada en utilisant des données d'études récentes dans les deux pays. Il appert que les choix des familles canadiennes sont semblables à ceux des familles américaines. Les calibrations d'un modèle de ces choix montrent les effets significatifs des subventions au soin des enfants, du prix des soins des enfants, et des taux de salaires sur ces choix. Cependant, aucun de ces facteurs n'explique les diffrences dans les patterns de choix entre les deux pays.     

Estimating Income and Price Elasticities of Trade in a Cointegration Framework

This paper presents further evidence on the empirical regularity known as the "45-degree rule." Income and price elasticities of trade are estimated for 21 countries in a cointegration framework. More specifically, the autoregressive distributed lag (ARDL) modeling approach and the DOLS procedure are adopted to estimate the long-run structure. The empirical results confirm the existence of a systematic relationship between growth rates and income elasticity estimates: faster growing economies have high income elasticities of demand for their exports but lower import elasticities, which implies that faster growth can be observed without any marked secular trend in real exchange rates.     

On the optimality of a minimum wage: New insights from optimal tax theory

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in productivity. The government does not observe workers' productivity but only their wages. Hence, the redistributive policy solves an adverse selection problem. We show that a minimum wage is optimal if the bargaining power of the workers is relatively low. However, if the government controls the bargaining power, then it is preferable to set a sufficiently high bargaining power.     

Discrimination and Disidentification: The Fair-Start Defense of Affirmative Action

The Fair-Start Defense justifies affirmative action preferences as a response to harms caused by race- and sex-based discrimination. Rather than base a justification for preferences on the traditional appeal to self-esteem, I argue they are justified in virtue of the effects institutional discrimination has on the goals and aspirations of its victims. In particular, I argue that institutional discrimination puts women and blacks at an unfair competitive disadvantage by causing academic disidentification. Affirmative action is justified as a means of negating this unfair disadvantage.     

Persistent Advantage or Disadvantage?: Evidence in Support of the Intergenerational Drag Hypothesis

By utilizing the Integrated Public Use Microdata Series (IPUMS) and a measure of occupational prestige (OCCSCORE) as a labor market outcome, the authors examine variations in the degree of labor market discrimination faced by several ethnic and racial groups in the United States between 1880 and 1990. Results demonstrate that the sharpest decline in labor market discrimination against blacks occurred between 1960 and 1980. For black males the extent of labor market discrimination was greater in all census years in IPUMS after 1880 until 1970, evidence contradicting the conventional expectation that market-based discrimination will decline progressively over time by dint of competitive pressure. Finally, after replicating George Borjas' "ethnic capital" exercise, the authors pool the 1880, 1900, and 1910 data to determine the relative magnitude of a group's gains and losses in occupational prestige due to group advantage or disadvantage in human capital endowments and due to favorable or unfavorable treatment (nepotism or discrimination) of those endowments in the labor market. The authors then examine statistically whether the group human capital advantage or disadvantage and group exposure to nepotism or discrimination at the turn of the century affects labor market outcomes for their descendants today. Results indicate strong effects of the past on present labor market outcomes. Hence, the essence of the study is the statistical demonstration that there are significant and detectable effects on current generations of the labor market experiences of their racial/ethnic ancestors.     

Politics, Insurance Regulation, and Unfunded Pension Liabilities

ABSTRACT: Insurance regulators operate in an environment in which resources are scarce and issues are most often complex and not salient to affected persons. Consequently, regulatory agencies, such as the Pension Benefit Guaranty Corporation (PBGC), need to use resources efficiently by making issues salient and not complex if regulatory goals are to be attained. To further its goal of full funding of defined benefit pension plans, the PBGC annually published a list of the Top Fifty Companies With the Largest Underfunded Pension Liability (LIST). This article investigates the issue of the economic effects of pension plan disclosure by measuring the share price response of the companies included on the LIST; then policy implications are drawn. The event study findings show that, on average, publication of the LIST did not have a negative effect on firm value. However, cross-sectional analysis provides some support for the contention that publication of the LIST had an economic cost on LISTed firms. The authors' results show that the value of large firms on the PBGC's list is less negatively affected at arrival (ARRIVAL) than smaller LISTed firms. Conversely, when firms leave the list (DEPARTURE), the value of large growth-oriented firms is more negatively affected than the value of other firms that reduce their unfunded pension liability. From a policy perspective, as hypothesized by Meier (1991), the PBGC used its scarce resources effectively by publishing the LIST. The issue of unfunded pension liability became less complex and more salient to interested parties. Consequently, consumer groups and political elites provided their support to further the regulatory agency's stated goal, which was the full funding of defined benefit pension plans. Furthermore, increased awareness of the underfunding problem contributed to the passage of the Retirement Protection Act of 1994.     

Employment and Prices in a Simple Macroeconomy

This exercise sets up interlinked labor and goods markets in a classroom macroeconomy. Students with worker roles are endowed with labor that can be consumed or sold to firms that post wages, purchase labor, and produce goods that can be either consumed or sold to workers. The money from sales is used by firms to purchase labor in the next period. Complicated record keeping is avoided by using ordinary playing cards to represent money and goods. The exercise can stimulate a discussion of potential output, unemployment, and the role of money in determining wages and prices. Use: This experiment can be used in introductory macroeconomics classes to teach concepts of the circular flow, real and money wages, unemployment, and labor market equilibrium and in intermediate classes to consider Keynesian and quantity theories. Time required: Fifteen minutes for reading instructions, 30 to 45 minutes for trading (depending on the number of periods), and 15 minutes for discussion. Materials: You will need one copy of the instructions for each person and one deck of ordinary playing cards for each replicated group of two workers and one firm. No money or other incentives are required.
