A growing body of evidence suggests that an important reason why firms do not change prices nearly as much as standard theory predicts is out of concern for disrupting ongoing customer relationships because price changes may be viewed as "unfair". Existing models that try to capture this concern...

We find evidence that the law of one price (LOOP) holds more nearly for country pairs that are within geographic regions than for country pairs that are not. These findings are established using consumer price data from 23 countries (including data from eight North American cities.) We find that...

House prices in the United Kingdom rose rapidly in recent years. The run-up, larger than any other in U.K. history, leveled off early last year. House prices are currently declining at rates faster than those seen in the early 1990's downturn. The housing downturn, however, is far from complete....

The goal of this study is the derivation and application of a direct characterization of the inverse of the covariance matrix central to portfolio analysis. As argued below, such a specification of the inverse, in terms of a few primitive constructs, helps clarify the determinants of such key...

An unresolved issue in international macroeconomics is the apparent lack of risk-sharing across countries, which contradicts the prediction of models based on the assumption of complete markets. We assess the importance of financial frictions in this issue by constructing an incomplete market...

This paper develops an alternative test of the neutrality of anticipated monetary policy. A multi-good equilibrium model along the lines of Barro and Hercowitz is used to derive a neutrality proposition for anticipated movements in the aggregate price level and to demonstrate econometrically its...
