In this paper we derive a model of aggregate investment that builds from the lumpy microeconomic behavior of firms facing stochastic fixed adjustment costs. Instead of the standard sharp (S,s) bands, firms' adjustment policies take the form of a probability of adjustment (adjustment hazard) that...

This paper argues that, despite important productivity gains, reforms have benefited consumers much less than expected in El Salvador. Antitrust legislation, consumer protection and an adequate regulation of privatized utilities are central ingredients of a successful market economy. Major...

Microeconomic flexibility is at the core of economic growth in modern market economies because it facilitates the process of creative-destruction, The main reason why this process is not infinitely fast, is the presence of adjustment costs, some of them technological, others institutional. Chief...

In this paper we derive a model of aggregate investment that builds from the lumpy microeconomic behavior of firms facing stochastic fixed adjustment costs. Instead of the standard (S,s) bands, firms' optimal adjustment policies are probabilistic, with a probability of adjusting (adjustment...

We characterize the degree of microeconomic inflexibility in several Latin American economies and find that Brazil, Chile and Colombia are more flexible than Mexico and Venezuela. The difference in flexibility among these economies is mainly explained by the behavior of large establishments,...

Americans who are caught evading taxes in one year may be audited for prior years. While the IRS does not disclose its method of selecting tax returns to audit, it is widely believed that a taxpayer's probability of being audited is an increasing function of current evasion. Under these...

Microeconomic flexibility, by facilitating the process of creative-destruction, is at the core of economic growth in modern market economies. The main reason for why this process is not infinitely fast, is the presence of adjustment costs, some of them technological, other institutional. Chief...

Cooper and Willis (2003) is the latest in a sequence of criticisms of our methodology for estimating aggregate nonlinearities when microeconomic adjustment is lumpy. Their case is based on reproducing' our main findings using artificial data generated by a model where microeconomic agents face...

This paper studies quarterly employment flows of approximately 10,000 large U.S. manufacturing establishments during 1972:1-1980:4.After estimating the extent of short run microeconomic substitution between employment and hours per worker (hours-week), we construct measures of the path of the...
