This paper explores the existence and examines the characteristics, if any, of business cycles in Singapore. Specifically, the authors ask: Is there a business cycle in Singapore? Is there a Singaporean business cycle? Unlike earlier studies, this paper investigates whether or not there exists a business cycle in Singapore and employs cross-spectral analysis and factor analysis which have advantages over the time-domain techniques. The study shows that there is a business cycle in Singapore and its frequency does not coincide with the periodicity of the two recessions experienced by the country. However, the business cycle is not in any meaningful way Singaporean, as evidenced by the existence of three international factors explaining about 99 percent of the common variance of the series. The idiosyncratic factor is well below 1 percent in all Association of Southeast Asian Nations countries with the exception of the Philippines. The findings have a number of significant implications both from the theoretical and policymaking viewpoint.  相似文献

This paper reports on the importance of firm entry and growth flows in Portuguese manufacturing during the period 1982–86, and investigates their determinants. We find that both movements are induced by past profitability and deterred by economies of scale, product differentiation and sunk costs. The analysis does not reject the hypothesis that the determinants of firm entry and growth are quantitatively the same, thereby giving some support to the hypothesis that entry and expansion are close substitutes in absorbing industry excess profits, and that the choice between them does not depend on the height of the entry/mobility barriers.  相似文献

Summary. By generalizing the classical Knaster-Kuratowski-Mazurkiewicz Theorem, we obtain a result that provides sufficient conditions to ensure the non-emptiness of several kinds of choice functions. This result generalizes well-known results on the existence of maximal elements for binary relations (Bergstrom [4]; Walker [16]; Tian [15]), on the non-emptiness of non-binary choice functions (Nehring [12]; Llinares and Sánchez [9]) and on the non-emptiness of some classical solutions for tournaments (top cycle and uncovered set) on non-finite sets.

The objective of this paper is to examine hypotheses about the relationships between socio-economic factors, risk factors in working life, and the occurrence of mental illness, together with the degree of quality of life and consumption of health care, costs for health care, and costs for social insurance. This is a prospective and longitudinal study of 1,347 individuals of an active working age, 18–64 years, who have been on sick leave for more than 30 days. The group is characterized by the prevalence of risk factors in their work environment and welfare losses, such as multiple health problems, poor quality of life, inability to work, and dependency on society's support from health care and social insurance. The costs for health care were just over 2.8 million SEK, or 30 percent higher for those with psychological distress as compared to the group without. The payments from social insurance also increased by approximately 15 percent. The relatively greater weighting of health care costs and sickness cash benefits were motivating factors to study whether this group had an optimal amount and quality of health care, or if the resources available for health care should be distributed in another way that better satisfies the needs of the group.  相似文献

Our economic system, the market economy, is a part of a broader system or “society.” We frequently study the operation of the market economy as if it were autonomous, even though there are many complex and mutual relationships between society, the economic system and the other systems – political, cultural, religious, legal, etc. – that form part of society. In a market economy we may identify several components: a frame or background in which the economic activity takes place, a set of ideas and theories, the values shared by this society, the set of institutions, norms and rules that control the economic behavior of people, and the incentives or motivations of the economic agents. The play of these elements defines the operation of a market economy. Is ethics an institution, or does it belong to the set of values and ideas? In this paper I will discuss the role of institutions, norms and rules in society, with special reference to the economic system, in order to gain insight into the relationship between institutions and ethics. I study first the concept and features of social institutions and norms; second, institutional change, and third, the relationship between ethics and institutions.  相似文献

This paper suggests that accounting and auditing systems can be effective devices to counteract tendencies for firm risk-taking associated with bank safety nets. Results are obtained from an international sample of publicly traded banks after controlling for other regulatory control devices for bank risk such as restrictions on banking activities, minimum regulatory capital requirements and official discipline. The efficacy of accounting and auditing systems in controlling bank risk diminishes with bank charter value and increases with moral hazard stemming from a country's deposit insurance. The results also indicate that accounting and auditing systems are complements for minimum capital requirements, but substitutes for restrictions on bank activities and official discipline.  相似文献

We analyze the evolution of market power in the main banking sectors of the European Union. The evolution of the relative margins does not show an increase in the degree of competition within the EU. The explanatory factors of the relative margins most directly related to market power are not significant, and even have a negative influence (concentration in the deposits market). The size and efficiency of banks, default risk, and the economic cycle have a notable capacity to explain the behavior of the market power. The results show the inadequacy of using concentration measures as proxy for the competition environment in banking markets.  相似文献
