This paper investigates the redistributive effects of taxation on occupational choice and growth. We discuss a two-sector economy in the spirit of Romer (1990). Agents engage in one of two alternative occupations: either self-employment in an intermediate goods sector characterized by...

We study the relationship between default and the maturity structure of the debt portfolio of a Sovereign, under uncertainty. The Sovereign faces a trade-off between a future costly default and a high current fiscal effort. This results into a debt crisis in case a large initial issuance of long...

We study a model where investment decisions are based on investors’ information about the unknown and endogenous return of the investment. The information of investors consists of endogenously determined messages sold by financial analysts who have access to both public and private information...

We quantify the inefficiency of the retirement component of the US social security system within a model where agents receive idiosyncratic labor-productivity shocks that are privately observed

This paper considers two models to deal with an outcome variable that contains a large fraction of zeros, such as individual expenditures on health care: a sample-selection model and a two-part model. The sample-selection model uses two possibly correlated processes to determine the outcome: a...

This paper compares the goodness-of-fit and the stability of six methods used to extract risk-neutral probability density functions from currency option prices. We first compare five existing methods commonly employed to recover risk-neutral density functions from option prices. Specifically, we...

This paper investigates the aggregate fluctuations in production and demand components when a firm's investment decision takes the form of (S,s) policies. In the field of large-dimensional non-linear dynamical systems, it is a commonly accepted view that a system of coupled non-linear...

Previous efforts to compare the costs and benefits of fixed versus flexible exchange rate regimes have ignored the fact that it takes significant resources and time to develop export markets, and they have not included an analysis of the firm-level decision to enter or exit export markets. This...
