生产性老龄化:理论与应用视角

有关老龄化社会的讨论大多负面地将重点放在这些严重的挑战上,当然形势的确不容乐观。这类讨论一般只考虑老年人给经济、卫生保健、社会福利体系所造成的负担;并未考虑故事的\"另一面\",即人口结构变化的积极面:老年人寿命延长并且健康。在世界各地的许多发达国家和发展中国家,60岁的成年人仍可预期再拥有20至30年以上的寿命。此外,老年群体的受教育水平越来越高②。     

The value of entrepreneurship by gender on regional behaviour

This paper examines how the value of entrepreneurship by gender is related to regional behaviour. Researchers have traditionally defined entrepreneurial organization as separate to gender and to economic growth. Using the Global Entrepreneurship Monitor (GEM) we complete a dataset of 50 countries using variables such as total early-stage entrepreneurial activity (TEA) and opportunity-driven entrepreneurial activity (OPP). The methodology used proposes an analysis of regional convergence, comparing the evolution over time of both the rate of entrepreneurial activity and the ratios of opportunity-driven and need-driven entrepreneurial activity, distinguishing by gender. On the other hand, a regression model is proposed that explains the greater presence of female entrepreneurship. The results show that entrepreneurship by gender is an important factor to define different cluster of countries according to how men and women entrepreneurs create new economic opportunities.

Persistent gaps and default traps

We show how vicious circles in countries' credit histories arise in a model where output persistence is coupled with asymmetric information about output shocks. In such an environment, default signals the borrower's vulnerability to adverse shocks and creates a pessimistic growth outlook. This translates into higher interest spreads and debt servicing costs relative to income, raising the cost of future repayments, thereby creating “default traps”. We build a long and broad cross-country dataset to show the existence of a history-dependent “default premium” and of significant effects of output persistence on sovereign creditworthiness, consistent with the model's predictions.     

Brazilian OFDI Determinants

Recently, the global economy assumed a new setting in which emerging economies began to make substantial investments in the international market. This study aimed to investigate the determinants of outward foreign direct investment from Brazil from 2002–2011. The proposed models developed included attractiveness of the host country, characteristics of home country, and firms’ strategies. The results corroborate the existing argumentations concerning adaptation of mainstream theory with respect to the realities of emerging economies. Brazilian multinationals do not internationalize their activities in pursuit of cost reduction, efficiency, or to explore new markets or natural resources of the host countries. Results show that Brazilian investments were attracted by the availability of skilled labor, openness of the host market, geographic proximity, improved financial conditions of Brazilian companies, and national companies’ strategy of reaffirmation and consolidation as global players.     

From global start-ups to the borderless firm: Why and how to build a worldwide value system

Although the original concept of international new ventures included the geographic configuration of value activities, the subsequent development of the literature has gradually abandoned the concern about the geographic configuration of both input sourcing and output marketing to concentrate almost exclusively on the latter. Therefore, this paper argues that there is a need to re-focus the research so as to figure out how and why some companies are borderless. Borderless firms are defined as the result of the combination, early on, of geographically dispersed resources and capabilities, defying the home-base logic. A borderless firm presents the following characteristics (or a combination of them) from inception (or shortly thereafter): (i) value-added activities dispersed across different countries and regions; (ii) entrepreneurs not bounded by a home base; (iii) multinational founders and/or management teams; and (iv) a multinational workforce. To enquiry into this issue, the study uses five case studies of borderless firms. The results advance the understanding of the motives and processes behind the development, early on, of a borderless configuration of value activities.     

EXAMINATION OF A PATH MODEL RELATING INFORMATION TECHNOLOGY INFRASTRUCTURE WITH FIRM PERFORMANCE

This article draws on the resource‐based view of the firm to investigate the mechanisms through which information technology (IT) impacts firm performance. Research suggests that the relationship between IT and firm performance may be both direct and indirect. In this study, a path model is tested that proposes a firm's IT infrastructure resources as having both a direct impact on organizational performance, as well as an indirect effect that is propagated through its impact on an intermediate organizational resource, a firm's logistics information system (LIS). The results suggest that positive firm performance may be derived directly from an organization's superior IT infrastructure, as well as indirectly, through its enabling impact on LIS's. These findings contribute to our understanding of the nature of the relationship between IT and firm performance by exploring the value of IT at both the process and organizational levels.
