Real options approach-based demand forecasting method for a range of products with highly volatile and correlated demand

To achieve a competitive edge needed for marketing highly competitive products, modern enterprises have actively sought to provide the marketplace with an expansive range of products with high random volatility of demand and correlations between demands of product. Consequently, traditional forecasting methods for separately forecasting demand for these products are likely to yield significant deviations. Therefore, this study develops a real options approach-based forecasting model to accurately predict future demand for a given range of products with highly volatile and correlated demand. Additionally, this study also proposes using Monte Carlo simulation to solve the demand forecasting model. The real options approach associated with Monte Carlo simulation not only deals effectively with random variation involving a particular demand stochastic diffusion process, but can handle the correlations in product demand.

我国外贸企业人民币升值加息双重风险同步管理与独立管理比较研究

我国出口外贸企业将来收到外汇货款又要借款用于生产,企业面临很大人民币汇率利率双重风险,因此迫切需要解决其风险管理问题。可以使用目前市场上交易的人民币外汇远期、外汇期货和利率远期等衍生工具,分别对这两项风险进行独立管理和同步管理。导出策略的回报、风险和效率等统计指标,比较评价这两种风险管理策略的优良性。得到同步管理比独立管理更加优越的结论,企业可以使用同步管理策略更有效地规避所面临的双重风险。

Multivariate option pricing using copulae

The complexity of financial products significantly increased in the past 10 years. In this paper, we investigate the pricing of basket options and more generally of complex exotic contracts depending on multiple indices. Our approach assumes that the underlying assets evolve as dependent GARCH(1, 1) processes. The dependence among the assets is modeled using a copula based on pair‐copula constructions. Unlike most previous studies on this topic, we do not assume that the dependence observed between historical asset prices is similar to the dependence under the risk‐neutral probability. The method is illustrated with US market data on basket options written on two or three international indices. Copyright © 2012 John Wiley & Sons, Ltd.
