Casino regulations and economic welfare

Abstract This paper studies the entry and tax regulation of oligopolistically competitive privately run casinos and government‐run casinos in a jurisdiction. We highlight three important external effects from casino‐style gambling: non‐casino income creation, social disorder costs, and cross‐border gambling. The laissez‐faire equilibrium need not be overcrowding compared with regulated or government‐run regimes. Entry regulation may lead to higher jurisdiction welfare than tax regulation. Government‐run casinos always operate on a larger scale and achieve higher welfare than other regimes, given the same number of casinos. With an endogenous fraction of external gamblers, a dispersed casino configuration yields higher welfare than a centralized one.

服务外包风险及控制

随着服务外包范围扩大、涉及内容的增加,服务流程的复杂性强化了风险的不确定性,处于不同发展阶段的企业会面临着不同的风险。因此,要依据不同外包企业的具体情况来预测企业未来的风险,并采取相应的规避措施：选择稳健的外包方式和服务外包提供商;订立完善的外包协议;建立良好的控制机制;严格管理外包服务流程,严防内外合谋的操作性风险;重视知识产权保护,构建诚信的商业环境;建立外包应急机制,控制集中风险;加强与承包商之间的交流与沟通,规避文化差异风险。     

Globalizing Business Ethics Research and the Ethical Need to Include the Bottom-of-the-Pyramid Countries: Redefining the Global Triad as Business Systems and Institutions

A majority of the countries in the world are still considered “developing,” with a per capita income of less than U$1,000. Hahn (2008, Journal of Business Ethics 78, 711–721) recently proposed an ambitious business ethics research agenda for integrating the “bottom-of-the-pyramid” countries (Prahalad and Hart, 2002, Strategy and Competition 20, 2–14) through sustainable development and corporate citizenship. Hahn’s work is among the growing field of research in comparative business ethics including the global business ethics index (Michalos, 2008, Journal of Business Ethics 79(1), 9–19; Scholtens and Dam, 2008, Journal of Business Ethics 75(3), 273–284; Tsalikis and Seaton, 2008, Journal of Business Ethics 75(3), 229–238). This article is complementary to Hahn’s work and it advocates an urgent need for business ethics researchers to globally integrate the bottom-of-the-pyramid countries through a fundamental re-definition of the global economic triad, including the United States, Western Europe, and Japan [Ohmae, 1985, Triad Power: The Coming Shape of Global Competition (New York: Free Press)]. The definition that we propose is based on business systems and institutional perspectives that include the bottom-of-the-pyramid countries. We also propose to broaden the research in business ethics to enable comparisons across business systems indifferent income levels.

Illegal immigration in a heterogeneous labor market

This paper examines the effects of illegal immigration in a neoclassical growth model with two groups of workers, skilled and unskilled. We show that although illegal immigration is a boon to a country as a whole, there are distributional effects, whose sign is in general ambiguous. This is because all sources of income of both groups are affected and some of these changes tend to move income in opposite directions. Nevertheless, calibration exercises show that the wealth distribution is likely to become more unequal as the number of illegal immigrants increases. We confirm most of our calibration results analytically in a small open economy version of the basic model. Finally, our results remain robust when we extend the model to allow for endogenous skill acquisition.

Predictability of nonlinear trading rules in the U.S. stock market

Most of the existing technical trading rules are linear in nature. This paper investigates the predictability of nonlinear time series model based trading strategies in the U.S. stock market. The performance of the nonlinear trading rule is compared with that of the linear model based rules. It is found that the self-exciting threshold autoregressive (SETAR) model based trading rules perform slightly better than the AR rules for the Dow Jones and Standard and Poor 500, while the AR rules perform slightly better in the NASDAQ market. Both the SETAR and the AR rules outperform the VMA rules. The results are confirmed by bootstrap simulations.     

Strategic Choices,Environmental Uncertainty and SBU Performance: A Note on the Intervening Role of Management Accounting Systems

This paper examines the role of management accounting systems (MAS) design on the relationship between: (1) strategic business unit (SBU) strategy and SBU performance and (2) perceived environmental uncertainty (PEU) on SBU performance. MAS design was defined in terms of the extent to which managers use broad scope MAS information for managerial decision making. The responses of 62 SBU managers, drawn from a cross-section of manufacturing companies in Western Australia, to a questionnaire survey were analysed by using a path analysis. The results suggest that SBU strategy and PEU are important antecedents of MAS design, and that broad scope MAS information is an important antecedent of SBU performance.     

城镇化与三农问题的解决

受全球经济危机影响,中国必须靠扩大内需来保持经济增长。实施城镇化战略既可以扩大内需,又可以为解决"三农"问题提供新思路。在推进城镇化时,一方面要促使农民从农村离得开,另一方面也要确保农民在城镇住得下。离得开的关键是农民承包地及宅基地确权,而住得下的关键是解决进城农民的就业、住房、社会保障问题,同时还要进行户籍改革。
