While the financial protection measures enacted by the ECB and the community of Eurozone members have calmed financial markets, they have left the competitiveness problem of the Eurozone's southern countries and France unresolved. The paper compares price inflation before the crisis with the necessary and actual price cuts that have taken place since the outbreak of the crisis, predicting a decade of stagnation for the south and inflation for the north. Keynesian demand policy is counterproductive in the south and unnecessary in the north. The necessary realignment of relative goods prices and current account imbalances can be achieved if market forces are allowed to redirect capital flows to the north instead of being artificially steered to uses they are keen to avoid.  相似文献

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed.  相似文献

Many small firms in Sweden are characterized by a lack of equity capital. For several years measures to increase the equity capital have been discussed. In this discussion the private investors' market has received virtually no attention. This study presents some preliminary results of the private investors in Sweden.

The research in small firms financing is characterized by a lack of theoretical framework. One basic assumption in the study is that agency theory can provide an essential framework to explain the interaction between the private investor and entrepreneur. Twenty-five hypotheses generated from agency theory are formulated and tested on 62 small unlisted firms in Sweden. Multiple regression analysis is used for the causal analyses.

The empirical results in the study show inter alia that the geographic distance and the private investor's knowledge about the portfolio firm's transformation process seem to be the most influential factors for determining the private investor's involvement in the portfolio firms. It is also interesting to notice that none of the variables, frequency of contacts and the private investor's operational work in the portfolio firm affect the performance of the firm. Contrary to conventional wisdom, private investors do not add value to their portfolio firms through their interaction with the entrepreneurs.

The theoretical conclusion is that agency theory does not provide any satisfactory framework to explain the private investor - entrepreneur relationship. Some of the basic assumptions in agency theory seem to be invalid. A model for the relationship between private investors and entrepreneurs is developed in which four interaction strategies are identified. The model gives implications on two levels: the portfolio level and the individual case level.  相似文献

Dealing effectively with risks in complex projects is difficult and requires management interventions that go beyond simple analytical approaches. This is one finding of a major field study into risk management practices and business processes of 35 major product developments in 17 high‐technology companies. Almost one‐half of the contingencies that occur are not being detected before they impact project performance. Yet, the risk‐impact model presented in this article shows that risk does not affect all projects equally but depends on the effectiveness of collective managerial actions dealing with specific contingencies. The results of this study discuss why some organizations are more successful in detecting risks early in the project life cycle, and in decoupling risk factors from work processes before they impact project performance. The field data suggest that effective project risk management involves an intricately linked set of variables, related to work process, organizational environment, and people. Some of the best success scenarios point to the critical importance of recognizing and dealing with risks early in their development. This requires broad involvement and collaboration across all segments of the project team and its environment, and sophisticated methods for assessing feasibilities and usability early and frequently during the project life cycle. Specific managerial actions, organizational conditions, and work processes are suggested for fostering a project environment most conducive to effective cross‐functional communication and collaboration among all stakeholders, a condition important to early risk detection and effective risk management in complex project situations.  相似文献

Recent research has shown growing shares of employment in the social economy (or non-profit sector) both in the European Union and in the United States. In the EU, there seems to be growing hopes that the social economy will be capable of contributing to local progress on the unemployment issue in crisis regions. This paper analyses employment in certain entrepreneurial forms, usually considered belonging to the social economy, in Sweden during the 1990s. The results show considerable regional differences of employment in the social economy, but also that its share of the labor market is very limited. The effect of social-economic organizations on employment, therefore, is probably mainly indirect in as much as they function as platforms for cooperation between firms or else as embryos for enterprises by strengthening local entrepreneurship and helping to nurture a deposit of social capital which has visible effects on private business and jobs. However, these effects need more detailed examinations.  相似文献

Abstract

This article is a self-contained survey of utility functions and some of their applications. Throughout the paper the theory is illustrated by three examples: exponential utility functions, power utility functions of the first kind (such as quadratic utility functions), and power utility functions of the second kind (such as the logarithmic utility function). The postulate of equivalent expected utility can be used to replace a random gain by a fixed amount and to determine a fair premium for claims to be insured, even if the insurer’s wealth without the new contract is a random variable itself. Then n companies (or economic agents) with random wealth are considered. They are interested in exchanging wealth to improve their expected utility. The family of Pareto optimal risk exchanges is characterized by the theorem of Borch. Two specific solutions are proposed. The first, believed to be new, is based on the synergy potential; this is the largest amount that can be withdrawn from the system without hurting any company in terms of expected utility. The second is the economic equilibrium originally proposed by Borch. As by-products, the option-pricing formula of Black-Scholes can be derived and the Esscher method of option pricing can be explained.  相似文献

This paper identifies drivers of variations within air traffic systems highlighting inefficient mechanisms that can lead to system sub-optimality. Domestic air traffic in China is used as a case study. Airports need to respond to local demands with airlines that control parts of the system as agents. The relationship between the agent's behavior and system-wide variations in traffic movements shows how the collective behavior of a relatively few agents can disproportionately influence the system-wide traffic distribution.  相似文献
