Empirical Implications of Alternative Models of Firm Dynamics

Abstract: This paper considers two models for analyzing the dynamics of firm behavior that allow for heterogeneity among firms, idiosyncratic (or firm specific) sources of uncertainty, and discrete outcomes (exit and/or entry). Models with these characteristics are needed for the structural econometric analysis of several economic phenomena, including the behavior of capital markets when there are significant failure probabilities, and the analysis of productivity movements in industries with large amounts of entry and exit. In addition, these models provide a means of correcting for the self-section induced by liquidation decisions in empirical studies of firms responses to alternative policy and environmental changes. It is shown that the two models have different nonparametric implications - implications that depend only on basic behavioral assumptions and mild regularity conditions on the functional forms of interest (one distinction between them corresponds to the distinction between heterogeneity and an ergodic form of state-dependence; a form in which the effect of being in a state in a particular period erodes away as time from that period lapses). The nonparametric implications enable the construction of testing and selection correction procedures that are easy to implement (they do not require the computationally difficult, and functional-form specific, estimation algorithms that have been used to empirically analyze stochastic control models with discrete outcomes in the past). The paper concludes by checking for the implications of the two models on an eight-year panel of Wisconsin firms. We find one model to be consistent with the data for retail trade.

Is Theory Really Ahead of Measurement? Current Real Business Cycle Theories and Aggregate Labor Market Fluctuations

Abstract: In the l93Os, Dunlop and Tarshis observed that the correlation between hours and wages is close to zero. This classic observation has become a litmus test by which macroeconomic models are judged. Existing real business cycle models fail this test dramatically. Based on this result, we argue that technology shocks cannot be the sole impulse driving post-war U.S. business cycles. We modify prototypical real business cycle models by allowing government spending shocks to influence labor market dynamics in a way suggested by Aschauer (1985), Barro (1981, 1987) and Kormendi (1983), This modification can, in principle, bring the models into closer conformity with the data. While the empirical performance of the models is significantly improved, they still fail to account for the Dunlop-Tarshis observation. Accounting for that observation will require further advances in model development. Consequently, we conclude that theory is behind, not ahead of, business cycle measurement.

Social and economic impacts of climate

Abstract: For centuries, thinkers have considered whether and how climatic conditions-such as temperature, rainfall, and violent storms-influence the nature of societies and the performance of economies. A multidisciplinary renaissance of quantitative empirical research is illuminating important linkages in the coupled climate-human system. We highlight key methodological innovations and results describing effects of climate on health, economics, conflict, migration, and demographics. Because of persistent "adaptation gaps," current climate conditions continue to play a substantial role in shaping modern society, and future climate changes will likely have additional impact. For example, we compute that temperature depresses current U.S. maize yields by ~48%, warming since 1980 elevated conflict risk in Africa by ~11%, and future warming may slow global economic growth rates by ~0.28 percentage points per year. In general, we estimate that the economic and social burden of current climates tends to be comparable in magnitude to the additional projected impact caused by future anthropogenic climate changes. Overall, findings from this literature point to climate as an important influence on the historical evolution of the global economy, they should inform how we respond to modern climatic conditions, and they can guide how we predict the consequences of future climate changes.

The Gender Gap in Top Corporate Jobs

Abstract: This paper studies the gender compensation gap among high-level executives in US corporations. We use the ExecuComp data set that contains information on total compensation for the top five highest paid executives of a large group of US firms over the period 1992-1997. About 2.5% of the executives in the sample are women. These women earn about 45% less than their male counterparts. As much as 75% of this gap can be accounted for by the fact that women manage smaller companies and are less likely to be CEO, Chair, or President of their company. The unexplained gender gap can be reduced to less than 5% when one further accounts for the fact that female executives are younger and have less seniority than male executives. Over the period under study, women have nearly tripled their participation in the top executive ranks and have also strongly improved their relative compensation, mostly by gaining representation into the larger corporations. While the absence of a significant gender gap (once we control for measurable characteristics) implies that women and men who hold similar jobs in firms of similar size received fairly equal treatment in terms of compensation, it does not rule out the possibility of discrimination in terms of gender segregation or promotion.
