Increasing deer populations can be controlled through manipulatingharvest limits or season length. While such actions often result in benefitsto hunters, both motorists and the agricultural sector also benefit as alower deer population leads to fewer incidences of harmful human-deerencounters. Traditional recreation demand models are often employed toexamine the welfare implications of changes in daily hunting bag limits.Studies measuring the effects of changes in season length, however, arenoticeably absent from the literature. This study uses a nested randomutility model to examine hunter choice over site and season selection toderive the values of changes in season length. 相似文献

This paper provides additional empirical evidence on the topic of the effectiveness and the impact of Federal Reserve intervention on U.S. exchange rates. Using a daily measure of exchange rate intervention in the yen/dollar and mark/dollar exchange markets for the period January 3, 1985 to March 19, 1997, this paper finds a statistically significant impact of intervention on spot rates. A generalized autoregressive conditional heteroskedasticity exchange rate equation is used to measure the impact of intervention on exchange rate uncertainty. This study finds that intervention is associated with a significant increase in the interday conditional variance (uncertainty) of both bilateral spot exchange rates. This supports the view of Friedman and Schwartz that exchange rate intervention serves to destabilize the foreign exchange market by introducing additional levels of exchange rate uncertainty. 相似文献

This article is the first attempt in the literature to investigate the effects of public social security on aggregate consumption in a time-series setting for a developing country, Turkey that has one of the most generous social security systems in the organization for economic cooperation and development (OECD) region. In order to quantify the social security variable, this article uses the social security wealth (SSW) series calculated for Turkey in a separate study. This study indicates that SSW is the largest part of the household wealth in Turkey, and therefore should not be ignored in the aggregate consumption studies. The results show that its effect on consumption is positive and robust. 相似文献

"Purely predatory advertising" has been defined as advertising which redistributes market share but does not affect market demand. Purely predatory advertising is commonly assumed in the industrial economics literature; but its existence is an empirical question. Since cigarette advertising is widely considered to epitomize purely predatory advertising, we analyze firm level panel data for the United States cigarette industry to study the question of existence using an econometric procedure which corrects for autocorrelation and contemporaneous correlation. Statistical tests support the hypothesis that cigarette advertising is purely predatory. 相似文献

This study examines the effects of free trade between the U.S. and Mexico on the sectoral trade balance of the U.S. The empirical findings indicate that free trade would benefit the overall trade balance of the U.S., but the benefit will be small in the near to medium term for two reasons. First, there is a huge disparity between the economic sizes of the two countries. Second, a sizable share of Mexican exports already enter the U.S. under the Generalized System of Preferences (GSP) or at low rates under maquiladora production-sharing arrangements. The relatively low tariff rates already in effect allow most of the benefits of trade between the U.S. and Mexico to be realized and therefore limit the potential benefits to the U.S. from free trade. 相似文献

Conclusion This paper examines the change in exchange rate uncertainty between the Bretton Woods and floating exchange rate periods.
We estimate both the unconditional variance and the conditional variance of the DM/dollar exchange rate under each exchange
rate regime. The former is estimated on the basis of the coefficient of variation and the latter on the basis of a GARCH model.
Our GARCH results show that the unconditional variance greatlyunderstates the change in exchange rate uncertainty that resulted from the switch to a flexible exchange rate regime. 相似文献
