Assessing the importance of borrowing constraints for college entry is key for education policy analysis in the U.S. economy. I present a computable dynamic general equilibrium model with overlapping generations and incomplete markets that allows me to measure the fraction of households...

The authors argue that equilibrium unemployment has varied in the UK over the last twenty years, and that time series econometric methods have not always been suited to uncovering its evolution. Recent changes in the UK labour market seem to have had a significant impact on equilibrium...

This paper is concerned with univariate noncausal autoregressive models and their potential usefulness in economic applications. We argue that noncausal autoregressive models are especially well suited for modeling expectations. Unlike conventional causal autoregressive models, they explicitly...

In this paper we derive, under the assumption of Gaussian errors with known error covariance matrix, asymptotic local power bounds for seasonal unit root tests for both known and unknown deterministic scenarios and for an arbitrary seasonal aspect. We demonstrate that the optimal test of a unit...

Recent years have seen a surge in websites that provide news for free and, up to the end of 2001, daily newspapers in Italy have shown a growing trend towards making available online for free; the exact articles published on paper. To assess whether on-line news and traditional daily newspapers...

In this paper we examine some of the issues which will arise if the European Central Bank adopts "direct inflation" targeting after the adoption of the single currency in Europe. One issue is how big the deviations in national inflation rates form the European average might be. Another is the...

In this note I present a new set of simulated percentiles of asymptotic distributions regarding systems cointegration tests with a prior adjustment for deterministic terms suggested by Saikkonen & Lütkepohl (2000a, 2000b, 2000c). The new percentiles are based on an improved random number...

A fresh interpretaion is provided of the influential finding that the markup of prices over marginal costs is counter-cyclical. Using Rotemberg and Woodford's data set we argue that the markup is best modelled as a variable that is integrated of order one. A consequence of this finding is that...
