Linking Public Investment to Private Investment. The Case of Spanish Regions

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.     

论传统外部性理论解决环境代际外部性的失效

代际外部性问题主要是人类代际之间行为的相互影响,尤其是前代对后代、当代对后代的影响。在解决代际外部性上,施害者、受害者和政府生活在不同的时空中,新古典方法几乎就无能为力。产权的界定是在产权主体存在的前提下进行的,所以产权在代际进行界定是不可能实现的,所以通过科斯定理来消除代际的外部性也行不通。     

出口加工区的技术溢出效应的文献综述

我国从建立第一批出口加工区以来,至今已过去六个年头了.随着经济的发展,最初建立出口加工区以便于管理出口加工贸易的功能逐步转变为如何更好地拉动当地经济发展.本文对上世纪70年代以来国内外经济学在出口加工技术溢出效应地研究进行了总结,并指出研究的一些不足之处,以期为我国开展相应地研究提供借鉴.     

二元结构、劳动力转移与经济增长

我国经济存在典型的二元结构,大量农业劳动力的转移直接关系着我国的经济发展,改革后我国农业劳动力的转移速度较快,农业劳动力就业份额年均下降0.86个百分点,结构转换的资源再配置效应对经济增长的平均贡献率为17.26%,但目前我国二元经济结构还很明显,农业劳动力转移的任务还很艰巨,今后,应站在城乡统筹和经济持续发展的战略高度,考虑从两个途径采取措施,促进我国二元经济结构转换过程中的劳动力转移问题.     

旅游社区经济发展初步探讨

结合国内外学者对旅游社区的研究，重点分析了旅游社区的利益相关者，绘制出了旅游社区利益相关图，并尝试性地构建了旅游社区经济的发展模型。旅游社区是一个系统，政府、社区居民、旅游者和旅游社区内企业的共同作用是旅游社区经济发展的关键。同时，认为旅游孵化器和数字化、虚拟化旅游社区是旅游社区的两大走向。

Enterprise Risk Management and the Cost of Capital

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.     

Competitive pricing strategies in social networks

We study pricing strategies of competing firms selling heterogeneous products to consumers. Goods are substitutes and there are network externalities between neighboring consumers. In equilibrium, firms price discriminate based on the network positions and charge lower prices to more central consumers. We also show that, under some conditions, firms' equilibrium profits decrease when either the network becomes denser or network effects increase. In contrast, consumers always benefit from being more connected to each other. We determine the optimal network structure and compare uniform pricing and discriminatory pricing from the perspectives of firms and consumers.     

Marriage between credit cards and the Internet: Buying is just a click away!

This paper examines whether Internet access positively affects credit card balances. To that end, we compare the 2010 and 2013 Surveys of Consumer Finances, analyze the consistency of the results over time, and provide the rationale for any resulting differences. Using the censored techniques, our results indicate that Internet access has a positive effect on credit card balances, which suggests that consumers with Internet access are prone to higher balances compared to those without. The probability of carrying positive balances was larger in 2010 compared to 2013. Overall, the results suggest that, while the financial crisis might have contributed to higher balances in 2010, the economic recovery afterward seems to have eased the burden of credit card debt.
