全球化：前景、潜力与问题

本文扼要阐述了经济全球化发展的前景和潜力,并运用李嘉图模型对全球化可能导致的经济损害作出论证分析进而说明,尽管经济学家在极大程度上趋向于将全球化视为基本良性的现象,但全球化仍然对某些国家（包括发达国家）带来经济损害,及对部分人群可能造成极其痛苦的后果。不过,源自于全球化的不断增长的竞争压力,会加强创新和增长,从长远来看,的确对每个国家有利。     

Demand for Customized Products, Production Flexibility, and Price Competition

We examine markets where, in addition to production of standard (core) products, mass customization is technologically feasible. We compare a setting where a monopolist provides both standard and custom goods to a setting where an entrant joins the custom market and find customers' tastes affect the social desirability of entry. The entrant is unconcerned about the impact of its custom production on the incumbent's core product market and in some cases may supply more custom products than is socially desirable. Entry enhances (reduces) social welfare if consumers' core valuations are positively (negatively) related to their value added for customization.     

The effects of interactive leadership on human resource management in Singapore's banking industry

Reviewing the literature about interactive leadership and its effects on human resource management in business organizations, this paper proposes that interactive leadership has two major components: interaction skills and team building. Both components have positive effects on employees' trust in their leaders, on employees' motivation and employees' commitment to their companies. Based on these hypotheses, the paper develops an empirical test of the effectiveness of interactive leadership in Singapore's banking industry. Seventy-seven middle-level managers participated in this study by responding to a questionnaire about their leaders, their motivation, their commitment and their trust in these leaders. The results support the hypotheses and suggest some important implications for human resource management in business organizations, especially for human resource management in Oriental societies.     

Banknotes And Economic Growth

Modern paper currency contributes little to productive investment. This shortcoming is not inherent to paper money. It stems from the fact that currency today is monopolistically supplied by public monetary authorities that are poor intermediaries. Commercial banknotes may, in contrast, support efficient intermediation, just as private bank deposits do. We demonstrate this advantage in an endogenous growth model, and use the model to simulate, for a sample of developing countries, steady‐state growth‐rate gains from various degrees of banknote deregulation. The simulated gains are generally large compared with those from conventional forms of financial liberalization.     

Corruption in dictatorships

In this paper, we consider a simple model capable of explaining why some dictatorships choose to extract rents via seemingly inefficient institutions. In particular, this paper focuses on institutions associated with high levels of corruption and examines the conditions under which such institutions could serve the interests of a dictatorship. Developing such a model requires that we pose alternative institutions that dictators can choose to extract rents. Using this framework, this paper builds a model providing a theoretical basis for some stylized facts about the observed crosscountry variation in corruption levels. Specifically, the model motivates a rationale for the finding that higher levels of corruption are observed in countries characterized as having more heterogeneous populations, longer expected dictator tenure, and more severe punishment norms. The model is then estimated using international country level data.     

Social Capital and Social Influence on the Board of Directors

It is often assumed that directors with human capital such as prior management experience or independence from the company are the most influential board members. By contrast, in a survey of all the board members in 14 companies we found that ties to others in a network of strong ties among those who meet outside of board meetings were more important predictors of social influence than human capital or ties across boards. These ties within the board represent the social capital of members in the form of prior relationships with other directors, ties to others on the board, and membership in cliques within the board's network of ties. These results support a social capital perspective on influence that emphasizes relationships with others on the board as important factors in the social dynamics of board decision-making.     

Understanding prediction intervals for firm specific inefficiency scores from parametric stochastic frontier models

This paper makes two important contributions to the literature on prediction intervals for firm specific inefficiency estimates in cross sectional SFA models. Firstly, the existing intervals in the literature do not correspond to the minimum width intervals and in this paper we discuss how to compute such intervals and how they either include or exclude zero as a lower bound depending on where the probability mass of the distribution of \( u_{i} |\varepsilon_{i} \) resides. This has useful implications for practitioners and policy makers, with greatest reductions in interval width for the most efficient firms. Secondly, we propose an ‘asymptotic’ approach to incorporating parameter uncertainty into prediction intervals for firm specific inefficiency (given that in practice model parameters have to be estimated) as an alternative to the ‘bagging’ procedure suggested in Simar and Wilson (Econom Rev 29(1):62–98, 2010). The approach is computationally much simpler than the bagging approach.     

Product Differentiation and Public Education

We demonstrate that differentiation in public services can arise as a way of reducing competition among cities. Quality differentiation can be particularly relevant to the provision of education. If cities finance education through a property tax that generates "tax competition," we find that quality differentiation in education changes the amount of educational services provided. In the case of property-value maximization, this means a reduction in educational services in both the city with high quality and that with low quality. The reduction in educational services means that under reasonable conditions property values in both cities can increase.
