日语写作中学习者信念的差异与构成因素研究

通过从学习者的日语写作学习信念是否因日语水平而有差异、其构成因素两个角度分析了学习者的日语写作学习信念。结果表明：有些信念在不同水平学习者间存在差异,但整体差异并不明显;写作学习信念由元认知的重要性、借助外界资源、形式和内容并重、自我肯定4个因素构成。由此指出,日语写作课不能忽略元认知策略的指导,需导入自我修改活动,适当引入同学互评活动。     

Fiscal Stimulus and Endogenous Firm Entry in a Monopolistic Competition Macroeconomic Model

This paper sets up a monopolistic competition model featuring the returns to production specialization. Some novel results are derived from the analysis. First, the effect of a fiscal stimulus on consumption may be positive or negative, depending crucially upon whether the production function is characterized by increasing or decreasing returns to production specialization. Second, following a fiscal expansion, increasing returns to specialization lead to a positive linkage between real wages and aggregate output, while decreasing returns to specialization result in a negative relationship between real wages and aggregate output. Third, a fiscal expansion may raise social welfare, provided that the degree of increasing returns to production specialization is sufficiently large.     

Political and Economic Inequities and the Shaping of Institutions and Redistribution

This article studies the joint effect of political and economic inequalities on redistributive taxation and institutional quality. The theoretical model suggests that income inequality, coupled with political bias in favor of the rich, decreases redistribution and lowers institutional quality. The effect of the former is to increase productive investment, and the effect of the latter is to decrease it—with resulting ambiguous implications for economic growth. Testing these predictions empirically in a panel of countries, we find that inequality has a negative effect on both institutional quality and redistribution.     

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.
