This paper presents a new method to correct for measurement error in wage data and applies this method to address an old question. How much downward wage flexibility is there in the U.S? We apply standard methods developed by Bai and Perron (1998b) to identify structural breaks in time series...

This paper provides evidence that a time-varying risk premium is responsible for the rejection of the interest rate parity theory. We us a panel data set of returns on the Eurocurrency deposits and employ cross-section / time series methods to account for common movements in risk premia across...

We consider issues related to the order of an autoregression selected using information criteria. We study the sensitivity of the estimated order to i) whether the effective number of observations is held fixed when estimating models of different order, ii) whether the estimate of the variance...

This paper is concerned with the application of microeconomic theory to resource allocation in the transportation sector. The basic questions it addresses are how transportation should be priced and how capacity should be determined. Three models, the traditional highway pricing and investment...

Has financial liberalization improved the efficiency with which investment funds are allocated to competing uses? In this paper, we address this question, using firm level panel data from twelve developing countries. The basic idea is to investigate whether financial liberalization has increased...
