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...

Recently, there has been many applications of perturbation methods for solving stochastic dynamic general equilibrium models. However, in standard applications of the perturbation method, the Taylor expansion is always computed around the deterministic steady state. Because of nonlinearities,...

We analyze the microfoundations of the Phillips curve, a key relationship in general macroeconomics and models of monetary policy in particular. The form in current widespread use includes both forward looking expected inflation and lagged inflation. The presence of lagged inflation is necessary...

In this paper, we investigate the out-of-sample forecasting ability of a genetic program to approach the dynamic evolution of the Yen/US$ and Pound Sterling/US$ exchange rates, and verify whether the method can beat the random walk model. Later on, we use the predicted values to generate a...

This paper is related to a large recent literature studying the Phillips curve in sticky-price equilibrium models. It differs in allowing for the degree of price stickiness to be determined endogenously. A closed-form solution for short-term inflation is derived from the dynamic stochastic...

This paper aims at analyzing the welfare effects of allowing different levels of flexibility in the choice of the numbers of hours worked (part-time, full-time, extra-time). To do so we consider a setting with bargaining frictions, partially indivisible labor, heterogeneous agents and firms, and...
