Despite the strong pace of globalisation, the distance effect on trade is persistent or even growing over time (Disdier and Head, 2008). To solve this distance puzzle, we use the recently developed gravity equation estimator from Helpman et al. (2008) (HMR henceforth). Using three different data sets, we find that the distance coefficient increases over time when ordinary least squares (OLS) is used, while the non‐linear estimation of HMR leads to a decline in the distance coefficient over time. The distance puzzle, thus, arises from a growing bias of OLS estimates. The latter is explained by an increase in the importance of the bias from omitting the number of heterogeneous exporting firms relative to the bias from omitting zero trade flows. Furthermore, we show that including zero trade flows cannot solve the distance puzzle when using HMR. The HMR estimates are strongly correlated with the time pattern in freight costs reported by Hummels (2007). 相似文献

This paper analyzes long-term comovements between hedge fund strategies and traditional asset classes using multivariate cointegration
methodology. Since cointegrated assets are tied together over the long run, a portfolio consisting of these assets will have
lower long-term volatility. Thus, if the presence of cointegration lowers uncertainty, risk-averse investors should prefer
assets that are cointegrated. Long-term (passive) investors can benefit from the knowledge of cointegrating relationships,
while the built-in error correction mechanism allows active asset managers to anticipate short-run price movements. The empirical
results indicate there is a long-run relationship between specific hedge fund strategies and traditional financial assets.
Thus, the benefits of different hedge fund strategies are much less than suggested by correlation analysis and portfolio optimization.
However, certain strategies combined with specific stock market segments offer portfolio managers adequate diversification
potential, especially in the framework of tactical asset allocation.

This study investigates why financial markets react to the release of some economic indicators while ignoring others with similar informational content. Based on a Bayesian learning model, we show that the market impact of an economic indicator depends crucially on its early availability. The sequential introduction of the two largest German business surveys provides a natural experiment by which the model's implications are tested empirically. We show that even a large and well‐established indicator loses market impact if a similar indicator is launched and released earlier. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 30:909–937, 2010 相似文献

This paper investigates the international transmission of fiscal shocks between two closely‐linked, open economies. We estimate impulse response functions using a semi‐structural vector auto regressive (VAR) model and quarterly data from Australia and New Zealand for the period 1973:3–2008:4. We compare our empirical results with impulse response functions from a calibrated two‐country international real business cycle model with habit formation and adjustment costs to investment. We show that a positive shock to Australian government consumption leads to an increase in Australian output initially and then to a decline in the medium term, while the New Zealand output is negatively affected both in the short and medium term. This result is in line with the recent literature that reports beggar‐thy‐neighbour effect of positive government spending shocks. 相似文献

This study investigates the impact of international competitiveness on net employment, job creation, job destruction, and gross job flows for a representative sample of German establishments from 1993 to 2005. We find a statistically significant but economically small effect of real exchange rate shocks on employment, comparable to the one found in studies for the United States. However, contrary to the United States, the employment adjustment (among surviving firms) operates mainly through the job creation rather than the job destruction rate. Job destruction occurs essentially through discrete events such as restructuring, outsourcing and bankruptcy. We suggest that these findings are consistent with a highly regulated labor market, in which smooth adjustment is costly and possibly delayed. 相似文献
