This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.  相似文献

Vertical intra-industry trade and foreign direct investment in East Asia   总被引:4,自引:0,他引:4  
As economic integration in East Asia progresses, trade patterns within the region are displaying an ever-greater complexity: Though inter-industry trade still accounts for the majority, its share in overall trade is declining. Instead, intra-industry trade (IIT), which can be further divided into horizontal IIT (HIIT) and vertical IIT (VIIT), is growing in importance.In this paper, we set out to measure and examine vertical intra-industry trade patterns in the East Asian region and compare these with the results of previous studies focusing on the EU, to which such analyses so far have been confined. Based on the supposition that VIIT is closely related to offshore production by multinational enterprises, we then develop a model to capture the main determinants of VIIT that explicitly includes the role of FDI. The model is tested empirically using data from the electrical machinery industry. The findings support our hypothesis, showing that FDI plays a significant role in the rapid increase in VIIT in East Asia seen in recent years. J. Japanese Int.

Spatial determinants of Japanese FDI in China   总被引:4,自引:0,他引:4  
Research on foreign direct investment in China has spawned an increasingly large literature. Whilst regional cleavages with respect to the distribution of foreign direct investment (FDI) are acknowledged, empirical research on the spatial determinants of FDI in China has been limited. Furthermore, research on the spatial determinants of home country FDI in China has thus far been neglected due to difficulties in accessing the appropriate data. The objective of this paper is to examine the spatial determinants of Japanese direct investment in China by using an econometric model. To that purpose, a dataset is created from the Toyo Keizai directory on the overseas activities of Japanese companies. The results show that tertiary education, inland waterways, as well as coastal location are positive and significant determinants of Japanese investment in China.  相似文献

British public investment has declined sharply both as a share of GDP and as a share of government spending since the 1970s. Only part of this decline is explained by privatisation, which transferred some public investment to the private sector. More important was the very large and permanent reduction in public house‐building between the mid‐1970s and the early 1980s. Between the late 1980s and the early 1990s, the rate of public investment recovered somewhat, but after that time it declined again, reaching a record low in 1999. The most recent decline in public investment has affected a range of central government programmes, and it has not been significantly offset by investment under the Private Finance Initiative. The government now plans to increase investment spending, although levels look set to remain low by historical standards for some time to come.  相似文献

We investigate the investment decisions of Italian state-owned enterprises (SOEs) across budget constraint regimes and carry out a natural experiment that exploits a regime switch in 1987. Drawing on the theory of capital market imperfections, we apply an empirical framework for investment analysis to a panel of manufacturing SOEs in competitive industries. We identify parallels between SOEs and widely held, quoted companies afflicted by agency problems, managerial discretion, and overinvestment. We argue that, in the case of SOEs, the soft budget regime increases managerial discretion, facilitates collusion with vote-seeking politicians, and results in wasteful investment. Consistent with our predictions, we find that the regime switch disciplines SOE's investment behavior. Following a hardening of the budget constraint, managers lose discretion to indulge in collusion and overinvestment. J. Comp. Econ., June 2002 30(4), pp. 787–811.

阿弗奇—约翰逊模型(A—J模型)表明规制对象具有过度使用资本倾向,相应的实证检验中同时存在肯定和否定的结果,但基本的A—J模型、已有扩展和实证检验都忽略了受规制行业的峰荷需求特征。本文从基本的A—J模型出发,假定生产要素单位使用成本与规制机构所认可的单位核算成本不同,考察了峰荷需求特征下受规制网络型基础产业的投资行为,提供了资本配置效率的衡量标准。本文的基本结论在于,峰荷需求条件下受规制企业不一定投资过多,这也解释了为何A—J效应的实证检验存在相互矛盾的结果。  相似文献
