摘要：I consider the optimality of export subsidies in oligopolistic markets, when home and foreign firms have different costs and the social cost of public funds exceeds unity. Subsidies are optimal only for surprisingly low values of the social cost of public funds and, if subsidies are justified, they should be higher the more cost competitive are domestic firms. These results hold under both Cournot and Bertrand competition and in a two-period perfect equilibrium with learning by doing. The resu...

摘要：This paper studies the effects of supply and demand shocks on the optimal investment and savings decisions of economic agents in a small open economy. The two building blocks of the setup are adjustment costs in investment and a recursive time preference structure. It is shown that the model can mimic certain stylized facts.

摘要：This paper constructs a stochastic general equilibrium model of a small open economy consisting of risk-averse optimizing agents. The stochastic processes describing the rate of monetary growth, government expenditure, private production, and the foreign price level are taken to be exogenous, determining all asset risks and returns, and the equilibrium stochastic process describing the domestic inflation rate and the exchange rate. The model is used to examine the effects of the means and vari...

摘要：Consistent with the implications from a simple asymmetric information model for the bid-ask spread, we present empirical evidence that the size or the bid-ask spread in the foreign exchange market is positively related to the underlying exchange rate uncertainty. The estimation results are based on an ordered probit analysis that captures the discreteness in the spread distribution, with the uncertainty of the spot exchange rate being quantified through a GARCH type model. The data sets consis...

摘要：This paper studies the rationale for giving preference to domestic firms in the award of government contracts when the regulator is interested in maximizing domestic welfare. It is seen that, in the absence of comparative advantages, the regulator should discriminate in favor of the domestic firms, because foreign firms' profits do not enter in domestic welfare. Furthermore, I show that the form of the discrimination function depends on the mechanism being used. In order to simplify the implem...

摘要：This paper examines time-series properties of exchange rate changes, the forward premium and the forward bias in the context of a variant of Svensson's cash-in-advance model. The model is solved and simulated using realistic forcing processes whose law of motion is estimated from U.S.-Japan data and then approximated by a Markov chain. Although method of moments estimation shows that the over-identifying restrictions implied by the model are not rejected, it fails dramatically in producing a s...

摘要：We examine the role that news and heterogeneous expectations play in the persistence of exchange rate volatility, or so-called 'meteor shower' effects. Our empirical focus is on the U.S. trade balance news, which is shown to have a significant and persisting effect on the exchange rate and its conditional variance. Furthermore, the impact of U.S. trade balance 'news' is not isolated to the U.S. foreign exchange market. The degree to which U.S. trade balance 'news' affects other geographical ma...

摘要：This paper questions whether commodity taxation can ensure Pareto gains from trade liberalization in the presence of unemployment. To address this question, we extend the standard multi-consumer model of international trade to include efficiency-wage unemployment. Even if trade liberalization does not cause aggregate unemployment to rise, individual workers may lose jobs and would require compensation to maintain their pre-liberalization levels of welfare. This compensation would weaken the in...

摘要：This paper investigates the question of the optimal trade policies in the presence of foreign ownership, extending the framework of the pioneering studies by Brecher and Bhagwati. Trade in the ownership claims is explicitly modelled using a stochastic trade model. The paper concludes that the results of the above studies crucially depend on the policy not being expected at the time foreign investment takes place.
