The Costs of Non-Tariff Barriers to Trade: Evidence from New Zealand. — Recent work on trade policy with imperfect competition indicates that the adverse effects of non-tariff barriers to trade exceed those suggested by traditional theory. With market power in foreign supply, setting a restrictive non-tariff barrier will induce foreign exporters to raise their supply prices. The authors use the experiment provided by the comprehensive New Zealand economic reforms of the mid-1980s. Using panel data on export unit values from Germany and the United States to several destinations including New Zealand, they find some evidence for decreased export prices to New Zealand as a result of the dismantling of non-tariff barriers to trade. 相似文献

This paper develops a real option model in which the interaction between debt, liquidation policy and risky investments is studied. We consider a manager who owns the firm and faces the opportunity to invest in risky projects which may boost current profits at the cost of bankruptcy if they turn out to be unsuccessful. These investments are “last resort gambles” in the sense that, if successful, they save the company from insolvency, while, if unsuccessful, they make liquidation unavoidable. It is shown that last resort gambles delay liquidation. We study how the liquidation trigger and the last resort investment decisions are affected by the firm's capital structure. 相似文献

The classical forecasting theory of stationary time series exploits the second-order structure (variance, autocovariance, and spectral density) of an observed process in order to construct some prediction intervals. However, some economic time series show a time-varying unconditional second-order structure. This article focuses on a simple and meaningful model allowing this nonstationary behaviour. We show that this model satisfactorily explains the nonstationary behaviour of several economic data sets, among which are the U.S. stock returns and exchange rates. The question of how to forecast these processes is addressed and evaluated on the data sets. 相似文献
