The least squares (LS) estimator suffers from signicant downward bias in autoregressive models that include an intercept. By construction, the LS estimator yields the best in-sample fit among a class of linear estimators notwithstanding its bias. Then, why do we need to correct for the bias? To...

Cheung et al. (2004) use a vector error correction model (VECM) for the current float nominal exchange rate and the relative price data and claim that the sluggish Purchasing Power Parity (PPP) reversion is primarily driven by the nominal exchange rate, not by relative price adjustment, which is...

This paper provides an econometric analysis of the relationship between live and deceased (cadaveric) kidney donations for the United States for the period 1992:IV through 2006:II. Statistical analysis shows that increases in deceased donor transplants reduce future live donor grafts,...

This paper revisits the empirical evidence of purchasing power parity under the current float by the recursive mean adjustment (RMA) method (So and Shin, 1999). We first demonstrate superior finite sample performance of the RMA-based unit root test over the augmented Dickey-Fuller test via Monte...

Factor proportions trade theory focuses on wage adjustments to product prices and factor endowments estimated directly for the first time in the present paper with a structural vector auto regression. Yearly data cover the US wage, labor force, fixed capital assets, and relative prices of...

This paper seeks empirical evidence of nonlinear mean-reversion in relative national stock price indices for Emerging Asian countries. It is well known that conventional linear unit root tests suffer from low power against the stationary nonlinear alternative. Implementing the nonlinear unit...

Taylor (2002) claims that Purchasing Power Parity (PPP) has held over the 20th century based on strong evidence of stationarity for century-long real exchange rates for 20 countries. Lopez et al. (2005), however, found much weaker evidence of PPP with alternative lag selection methods. We...

This paper investigates evidence on the effect of dollar depreciation on the US tourism balance of trade. Export revenue and import spending functions are estimated separately with structural vector autoregressive methods to better capture the dynamic adjustment to exchange rate shocks....

This paper evaluates the degree of pass-through from oil price shocks to disaggregate U.S. consumer prices. We find significantly positive effects of the oil price shock only on energy-intensive CPIs, which imply that significantly positive, though quantitatively small, response of the total CPI...

This paper examines common forces driving the prices of 51 highly tradable commodities. We demonstrate that highly persistent movements of these prices are mostly due to the first common component, which is closely related to the US nominal exchange rate. In particular, our simple factor-based...
