Optimum choice of invoice currency with correlated exchange rates†

In this paper, we revisit optimal choice of invoice currency for an exporting firm in the face of exchange rate uncertainty. We demonstrate that when a vehicle currency is available, the optimum choice depends not only on the volatility of the exchange rates but the covariance between them as well. In particular, we show that when the exchange rates between the exporter and importer currencies on the one hand, and the exporter and the vehicle currency on the other, are positively correlated, vehicle currency becomes an attractive choice. The intuition underlying this novel outcome is that this regime dampens profit variability for the exporter.     

大型体育场馆工程项目LCP融资模式研究

大型体育场馆项目往往存在投资额巨大,融资模式单一,且建设和运营相脱节的现象。为了保证项目在全寿命期内的成功,设计了大型体育场馆工程项目的LCP融资模式。LCP模式不但将经营方引入项目的全生命周期,而且还设计了与该模型相匹配的风险分担、利益共享和信任机制,以保证公共利益和商业利益的实现。     

林业投资估价

分析了确定性条件下的林地估价的传统的Faustmann模型。用随机动态规划方法,建立了不确定性条件下林地估价模型,探讨了用LCP方法求解的问题,并得出有关结论。
