Growth & Welfare Effects of Business Cycles In Economies with Idiosyncratic Human Capital Risk
welfare cost of business cycles when markets are incomplete
This paper analyzes the welfare effects of business cycles when workers face uninsurable idiosyncratic labor income risk that has a cyclical component. In accordance with the recent literature, this paper assumes that eliminating business cycles amounts to integrating out aggregate shocks (the integration principle) and that idiosyncratic shocks and aggregate shocks are stochastically independent (the independence assumption). This paper provides two arguments why the previous literature has underestimated the welfare costs of business cycles. First, the welfare cost of business cycles are in general indeterminate, and the previous literature has only reported the lower bound that is consistent with the data. In a simple example calibrated to match the observed cyclical variations in displacement probabilities, the lower bound is .35 percent of average consumption and the upper bound is 1.39 percent (using log-utility). Second, the previous literature has only focused on cyclical variations in job displacement (unemployment) probabilities, but neglected cyclical variations in the average income loss of displaced workers. In a simple calibrated example, the introduction of cyclical variations in the average income loss of displaced workers increases the lower bound from .35 percent of average consumption to .94 percent and the upper bound from 1.39 percent to 1.89 percent (again for log-utility)welfare cost of business cycles, incomplete markets
Quitting and labor turnover : microeconomic evidence and macroeconomic consequences
Combining microeconomic evidence with macroeconomic theory, the authors present an integrated approach to wage and employment determination in an economy where firms pay above market"efficiency wages"to prevent trained workers from quitting. The model offers predictions about the behavior of formal employment, labor turnover, and segmentation in response to formal sector productivity shocks (including economic growth and tax reductions), changes in the desirability of self-employment (formal sector tax rates), and the cost of training a new worker. They use panel data from Mexican labor surveys to estimate the quit function derived fromthe model and the results support their view that transitions from formal salaried work to informal self-employment are quits rather than fires. (Quitting is positively related to the mean self-employment income and the probability of being rehired and negatively related to the mean formal salaried wage.) They then use the parameters estimated from the quit function to calibrate the model economy and simulate the impacts of economic shocks and policy innovations and find the impact on employment, turnover, and segmentation to be substantial.Environmental Economics&Policies,Public Health Promotion,Labor Policies,Economic Theory&Research,Labor Management and Relations,Health Monitoring&Evaluation,Banks&Banking Reform,Environmental Economics&Policies,Economic Theory&Research,Labor Management and Relations
Trade Policy, Income Risk, and Welfare
This paper studies empirically the relationship between trade policy and individual income risk faced by workers, and uses the estimates of this empirical analysis to evaluate the welfare effect of trade reform. The analysis proceeds in three steps. First, longitudinal data on workers are used to estimate time-varying individual income risk parameters in various manufacturing sectors. Second, the estimated income risk parameters and data on trade barriers are used to analyze the relationship between trade policy and income risk. Finally, a simple dynamic incomplete-market model is used to assess the corresponding welfare costs. In the implementation of this methodology using Mexican data, we find that trade policy changes have a significant short run effect on income risk. Further, while the tariff level has an insignificant mean effect, it nevertheless changes the degree to which macroeconomic shocks affect income risk.
