Knowledge that Transforms

Happiness is generally considered to be an ultimate goal in life; virtually everybody wants to be happy. The United States Declaration of Independence of 1776 takes it as a self-evident truth that the “pursuit of happiness” is an “unalienable right”, comparable to life and liberty. It follows that economics is – or should be – about individual happiness. In particular, the question is how do economic growth, unemployment and inflation, as well as institutional factors such as good governance, affect individual well-being? In addition to this intrinsic interest, there are three major reasons for economists to consider happiness. The first is economic policy. At the micro-level, it is often impossible to make a Pareto-optimal proposal, because a social action entails costs for some individuals. Hence an evaluation of the net effects, in terms of individual utilities, is needed. On an aggregate level, economic policy must deal with trade-offs, especially those between unemployment and inflation. Using happiness data for twelve European countries and the period 1975 to 1991, it has (cautiously) been calculated that a one percentage point increase in the unemployment rate is marginally compensated for by a 1.7 percentage point decrease in inflation (Rafael Di Tella, Robert MacCulloch, and Andrew Oswald 2001). This result significantly deviates from the “misery index ” which, for lack of information, has simply been defined as the sum of the percent unemployment rate and the percent annual inflation rate. Another trade-off that can be

McMillan and three anonymous referees for helpful comments, and to the National Institutes on Public opinion surveys uniformly show low support for medical care systems in developed countries. The longstanding conflict between equal access to care and efficient service provision partly explains this dissatisfaction. But the tradeoff is particularly acute in medical care, as new technologies developed over time have increased the cost of care and made the equity commitment even more expensive. Countries first dealt with rising costs by maintaining equal access and restricting total spending. Efficiency suffered, however. As a result, many countries are considering a move away from spending controls and towards incentive-based medical care reform.

This paper reviews the economics literature on welfare reform over the 1990s. A brief summary of the policy changes over this period is followed by a discussion of the methodological techniques utilized to analyze the effects of these changes on outcomes. The paper then critically reviews the econometric and experimental literature on caseload changes, labor force changes, poverty and income changes, and family formation changes. A growing body of evidence suggests that the recent policy changes have influenced economic behavior and well-being in a variety of ways. One particular set of "new-style" welfare programs seems to show especially promising results, with significantly increased work and earnings and reduced poverty.

This review culls noneconomic literature on education--by sociologists, anthropologists, and practitioners to present a new economic theory of students and schools. This theory elaborates two themes that have eluded economic analysis. First is the student as decision-maker whose primary motivation is her identity. Second is a conception of the school as a social institution. This framework suggests a new perspective on questions such as resource allocation and school reform. It explains why some educational policies succeed and others fail. We show how sociological variables may affect outcomes, and suggest ways economists can incorporate them into theoretical and empirical research.

We use data from a sample of child care centers to estimate the relationships between cost and child care quality, and between revenue and quality. We use a measure of child care quality, designed by developmental psychologists, that is positively associated with child development. Taking the estimated cost-quality and revenue-quality relationships as given, we estimate the objective functions of firms and compute the quality supply function. The results indicate that the supply of quality is moderately elastic with respect to price and the wages of child care center workers. Implications of the results for child care policy are discussed.

This paper examines the effects of work experience acquired while youth were in high school (and college) on young men's wage rates. Previous studies have found sizeable and persistent rates of return to working while enrolled in school, especially high school, on subsequent wage growth. We evaluate the extent to which these estimates represent causal effects by assessing the robustness of prior findings to controls for unobserved heterogeneity and sample selectivity. We explore more-general econometric methods for dealing with the dynamic of selection and apply them to data on young men from the 1979 National Longitudinal Survey of Youth (NLSY79). We find that the estimated returns to working while in high school or college are dramatically diminished in magnitude and are not statistically significant when one applies dynamic selection methods.

Strategic restructuring of firms through investment is key to a transition from plan to market. Using data on industrial firms in the Czech Republic during 1992-1998, we find that foreign-owned companies invest the most and cooperatives the least, that private firms do not invest more than state-owned ones, and that cooperatives and small firms are credit rationed. Given the large volume of nonperforming bank loans to firms and the high rate of investment of large state-owned and private firms, our findings also suggest that these firms operate under a soft budget constraint. Estimates of a dynamic model, together with the support for the neoclassical model, suggest that firms started to behave consistently with profit maximization.

Proponents of environmental policies based on liability assert that strict liability imposed on polluters induces firms to handle hazardous wastes properly. We examine unintended pollution releases, relating them to the liability imposed on polluters by state mini-Superfund laws. We find that strict liability reduces the frequency and severity of pollution releases, but that its effects vary with firm size. Smaller firms are associated with more pollution releases in states with strict liability, suggesting that in these states smaller firms may have specialized in riskier production processes. Their number, however, has not necessarily grown in response to the state's liability policy.

This paper investigates nonlinear features of FX volatility dynamics using estimates of daily volatility based on the sum of intraday squared returns. Measurement errors associated with using realized volatility to estimate ex post latent volatility imply that standard time series models of the conditional variance become variants of an ARMAX model. We explore nonlinear departures from these linear specifications using a doubly stochastic process under duration-dependent mixing. This process can capture large abrupt changes in the level of volatility, time-varying persistence, and time-varying variance of volatility. The results have implications for forecast precision, hedging, and pricing of derivatives.

This paper analyzes the evolution of inequality in Poland during the economic transition that began in 1989-1990. Using microdata from the Household Budget Surveys, we find that, after a brief spike in 1989, income and consumption inequality actually declined to below pretransition levels during 1990-1992 and then increased gradually, rising only moderately above pretransition levels by 1997. In sharp contrast, inequality in labor earnings increased markedly and consistently throughout the 1990-1997 period. We find that social transfer mechanisms, including pensions, played an important role in mitigating increases in both overall inequality and poverty. We argue that, from a political economy perspective, transfer mechanisms were well designed to reduce political resistance to market-oriented reforms in the early years of transition, paving the way for rapid growth. Finally, we provide cross-country evidence from the transition economies that is consistent with our interpretation of the Polish experience and is also consistent with recent work in growth theory suggesting that redistribution that reduces inequality can enhance growth.
