The traditional predictor of technical inefficiency proposed by Jondrow et al. (1982) is a conditional expectation. We study whether, and by how much, the predictor can be improved by using auxiliary information in the conditioning set. To do so, we use simulations to study two types of...

This paper proposes a moment-matching method for approximating vector autoregressions by finite-state Markov chains. The Markov chain is constructed by targeting the conditional moments of the underlying continuous process. The proposed method is more robust to the number of discrete values and...

Reasonably calibrated versions of the Diamond-Mortensen-Pissarides search and matching model of unemployment underpredict, by a wide margin, the volatility of vacancies, unemployment, and the vacancies-unemployment ratio - variables at the heart of this model. These shortcomings motivate two...

We study a market search equilibrium with aggregate uncertainty, private information and heterogeneus beiefs. Traders initially start out optimistic and then update their beliefs based on their matching experience in the market, using the Bayes rule. It is shown that all separating equilibria...

Recent financial crises in Europe as well as the periodic battles in the U.S. over the debt ceiling point to the importance of fiscal discipline among developed countries. This paper develops an open economy model, calibrated to the U.S. and a subset of the EMU, to evaluate the impact of various...

A simple equilibrium model of sectoral reallocation is developed in order to study the impact of heterogeneous moving costs on unemployment. The model blends key elements of standard sectoral reallocation theory and the competitive search model. Heterogeneity in moving costs is introduced via...

Motivated by large educational differences in geographic mobility, this paper considers a simple dynamic extension of Roy's (1951) model and analyzes it using new evidence on net versus excess mobility and the individual-level relationship between mobility and wages. According to the model, the...

In the US unemployment insurance (UI) system, only a fraction of those eligible for benefits actually collect them. We estimate this fraction using CPS data and detailed state-level eligibility criteria. We find that the fraction of eligible unemployed collecting benefits has been persistently...

Tax-based deficit reduction experiments for the U.S.\@ and EMU-12 are conducted using an open economy model. In welfare terms, raising the consumption tax is the least costly, followed by the labor income tax, then the capital income tax. Use of an open economy model means that the incidence of...
