Three potential sources of bias introduce complications for panel data estimation of the half-life of purchasing power parity deviations. They are bias induced by inappropriate cross-sectional aggregation of heterogeneous coefficients, small-sample estimation bias of dynamic lag coefficients,...

When the exchange rate is priced by uncovered interest parity and central banks set nominal interest rates according to a reaction function such as the Taylor rule, the real exchange rate will be determined by expected inflation and the output gap or the unemployment gap of the home and foreign...

We study the panel dynamic ordinary least square (DOLS) estimator of a homogeneous cointegration vector for a balanced panel of "N" individuals observed over "T" time periods. Allowable heterogeneity across individuals include individual-specific time trends, individual-specific fixed effects...

We study the evolution of the U.S. current account in a two-country dynamic stochastic endowment model in which a single non-state contingent bond is the only internationally traded asset. The paper focuses on the world 'saving glut' as the primary cause of continual deterioration in the current...
