Organizational Cultural Intelligence: A Competitive Capability for Strategic Alliances in the International Construction Industry

Cultural intelligence (CQ) on the organizational level is an organization's capacity to reconfigure its capability to function and manage effectively in culturally diverse environments and to gain and sustain its competitive advantages. This study aims to present a model, examining how organizational CQ through competitiveness framework might potentially affect the strategic alliancing ability of contracting firms operating abroad. The research involves a questionnaire survey conducted with the contracting firms. The research findings support the contracting firms leveraging their cultural intelligence as their main cross‐cultural competence for establishing and increasing the performance of international strategic alliances.     

ARBITRAGE‐FREE BILATERAL COUNTERPARTY RISK VALUATION UNDER COLLATERALIZATION AND APPLICATION TO CREDIT DEFAULT SWAPS

We develop an arbitrage‐free valuation framework for bilateral counterparty risk, where collateral is included with possible rehypothecation. We show that the adjustment is given by the sum of two option payoff terms, where each term depends on the netted exposure, i.e., the difference between the on‐default exposure and the predefault collateral account. We then specialize our analysis to credit default swaps (CDS) as underlying portfolios, and construct a numerical scheme to evaluate the adjustment under a doubly stochastic default framework. In particular, we show that for CDS contracts a perfect collateralization cannot be achieved, even under continuous collateralization, if the reference entity’s and counterparty’s default times are dependent. The impact of rehypothecation, collateral margining frequency, and default correlation‐induced contagion is illustrated with numerical examples.     

农业灌溉投资与灌溉用水的替代弹性分析

本文基于CES生产函数,利用我国12个省份2003-2005年的面板数据,实证分析了农业灌溉用水量与农田灌溉水利投入之间的关系.结果表明,亩均灌溉用水量与灌溉投资之间有较大的替代弹性,存在着很强的替代关系,这说明在给定的产出水平下,政府部门可调动多种投资主体的积极性,提高灌溉投资水平,达到对灌溉用水的替代,实现节约农田灌溉用水的目的.
