A note on the performance of regime switching hedge strategy

We characterize conditions under which the regime switching (RS) hedge strategy will perform better than the ordinary least squares (OLS) hedge strategy. The result can be extended to the case where the GARCH effects prevail. Specifically, these conditions would allow the RS‐GARCH hedge strategy to dominate both OLS and GARCH hedge strategies. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark

A note on the hedging effectiveness of GARCH models

This note compares the hedging effectiveness of the conventional hedge ratio and time-varying conditional hedge ratios (of which GARCH ratio is a special case). It is shown that, in large sample cases, the conventional hedge ratio provides the best performance. For small sample cases, a sufficiently large variation in the conditional variance of the futures return is required to produce the opposite result. The result is due to the fact that the hedging effectiveness measure is based upon the unconditional variance; meanwhile, the conventional hedge ratio minimizes the unconditional variance and the conditional hedge ratio aims at minimizing the conditional variance.     

Financial assistance for study abroad students: An economic analysis

This paper examines the scholarship payback policy embedded in a study abroad program. A full payback policy requires a student to return the whole amount of the scholarship should he fail to achieve a target post-program performance, whereas a partial payback policy requires a payback amount in proportion to the extent of the under-performance. It is found that, the university should adopt a fixed amount scholarship to maximize the average post-program ability. There is also an optimal partial payback policy.     

Hedging gas bills with weather derivatives

Natural gas company managers concerned with customer satisfaction attempt to minimize the occurrence of extreme bills. Previously, only price fluctuations were addressed with derivative instruments; exchange-traded weather derivatives present a means of hedging exposure to increases in quantity of gas demanded during colder than expected winter months. We model a natural gas company’s ability to adjust for consumer sensitivity and exposure to extreme bills with the use of an optimal mix of weather derivatives and gas pricing derivatives. We find consumer exposure to extreme bills is minimized when the utility uses pricing and weather derivatives.(JEL G11, L51)     

Can modeling the natural gas futures market as a threshold cointegrated system improve hedging and forecasting performance?

The calculation of the hedge ratio, and therefore the effectiveness of the hedge, is dependent upon the correct specification of the relationship between the futures and spot price. Likewise, a forecast of the future spot or futures price is dependent upon the model specification. This article investigates the appropriateness of using a threshold cointegrated model of the natural gas markets as the basis for hedging and forecasting. The findings suggest that the threshold model is more appropriate for longer contract length and that the threshold model does not offer much improvement in hedging or forecasting efficiency.     

Determinants of the Confucius Institute establishment

This paper investigates the determinants of the Confucius Institute (CI) establishment. It is shown that FDI, trade, geographical distance, developing country, and English speaking are important factors whereas GDP and population are marginally significant. Overall, CIs are under-represented in a non-English, distant, less wealthy developing country that trades infrequently with China. The results suggest that the CI network will have greater global impacts when new or more CIs are established in non-English speaking developing countries. However, potential mutual benefits between China and these under-representing countries should be preconditions in order to attract CIs in the countries.

Does the Confucius institute impact international travel to China? A panel data analysis

This article examines the impact of Confucius Institutes on inbound travel to China. We estimate a panel gravity model of inbound tourism flows to China between 2004 and 2010. We use a Poisson pseudo-maximum likelihood estimator to control for heteroscedasticity endemic in gravity models (Santos Silva and Tenreyro, 2006). We find that the presence of Confucius Institute(s) in the source country increases overall tourism in general and business and worker tourists in particular.
