When estimating the parameters of a process, researchers can choose the reference unit of time (unit period) for their study. Frequently, they set the unit period equal to the observation interval. However, I show that decoupling the unit period from the observation interval facilitates the...

The Efficient Method of Moments (EMM) estimator popularized by Gallant and Tauchen (1996) is an indirect inference estimator based on the simulated auxiliary score evaluated at the sample estimate of the auxiliary parameters. We study an alternative estimator that uses the sample auxiliary score...

We extend the existing literature on small mixed frequency single factor models by allowing for multiple factors, considering indicators in levels, and allowing for cointegration among the indicators. We capture the cointegrating relationships among the indicators by common factors modeled as...

We consider payment schemes in experiments that model infinite-horizon games by using random termination. We compare paying subjects cumulatively for all periods of the game; with paying subjects for the last period only; with paying for one of the periods, chosen randomly. Theoretically,...

We review the economics perspective on sustainable resource use and sustainable development. Under standard conditions, dynamic efficiency leads to sustainability of renewable resources but not the other way around. For the economic-ecological system as a whole, dynamic efficiency and...

This paper studies the effect of inflation on welfare in a monetary economy with price dispersion and consumer search. When facing greater price dispersion with higher inflation, consumers search harder for lower prices, and increased search raises welfare by intensifying market competition....

This paper documents a dramatic increase in the college enrollment rate of women from 1955 to 1980 and asks a quantitative question: to what extent can such increase be accounted for by the change in the female cohort-specific college wage premium? I develop and calibrate an overlapping...

The electronics industry has undergone a transformation from dominant vertically integrated firms to a system of lead firms that specialize in single slices of global value chains. We consider the role that modularization has played in this transformation, the insights this provides for our...

Every agent reports his willingness to pay for one unit of good. A mechanism allocates goods and cost shares to some agents. We characterize the group strategyproof (GSP) mechanisms under two alternative continuity conditions interpreted as tie-breaking rules. With the maximalist rule (MAX) an...

We survey the history of natural disasters in the Pacific Rim, and the region's vulnerabilities. We also discuss the extent of our knowledge about the short- and long-term economic impacts of these disasters, and prevention, mitigation and post-disaster policies that may be implemented.
