Competitive balance versus competitive intensity before a match: is one of these two concepts more relevant in explaining attendance? The case of the French football Ligue 1 over the period 2008–2011

The aim of this article is to investigate the determinants of attendance at French football Ligue 1 matches over the period 2008–2011 with an emphasis on examining the effects of both competitive balance and intensity before a match. Competitive balance is measured by the point difference between the two teams concerned by a match in the championship. Competitive intensity is measured by the point difference for the home team in relation to ranks with sporting stakes. Results show that competitive balance has an insignificant impact whereas competitive intensity has a significantly positive impact. Implications are drawn.     

Trade Unions and Consumerism

Public pension systems have long been a focus of special attention by neoclassical economics. In a context of intense aging processes, mainstream economists argue that the replacement of the pay-as-you-go pensions systems by unfunded individual savings accounts will have a positive impact, at a microeconomic and at a macroeconomic level, and will protect pension systems of the negative consequences of aging. However, these conclusions depend dramatically on the assumptions of rational expectations and perfect information. When we accept the existence of uncertainty, the presumed positive consequences of these reforms disappear, showing the advantages of pay-as-you-go over funded pension systems.     

The Limits of Organizational Change

The paper builds on the Marxist concept of exploitation to explore the meaning of the Post Keynesian notion of uncertainty. Uncertainty is mediated by institutions and is distributed unevenly among different social groups. As different historical social formations entail different institutional structures, the distribution and nature of uncertainty will also differ. The social configurations between class relations and uncertainty are analyzed for the capitalist, feudal and slave modes of production. It is demonstrated that modes of production do not only imply specific exploitative relations but also different relative distributions of uncertainty amongst classes. The joining of Marxian and Post Keynesian approaches allows for a richer understanding of exploitive relations and illuminates the full societal impact of uncertainty. It is shown that only in capitalism is the exploited class exposed to a substantial degree of economic uncertainty.     

Investment, uncertainty and irreversibility

This paper investigates the irreversibility of investments and the impact this has on the nature of the relationship between investment and uncertainty. The empirical analysis uses firm‐level data and is based on a survey of 210 rice‐milling firms in the Mekong River Delta in Vietnam, which was carried out during the year 2000. We show that uncertainty reduces investment of rice millers in the presence of irreversibility, as is predicted by the real options approach to investment. We do not find evidence that the negative association between uncertainty and investment is influenced by the degree of irreversibility.     

The link between inflation and inflation uncertainty: Evidence from G7 countries

In this paper we adopt the Markov-switching heteroscedasticity model to analyse the inflation series for G7 countries and examine the interaction between inflation rate and its uncertainty over both the short- and long-run. It is found that the relationship between inflation and inflation uncertainty depends on whether the shock is permanent or transitory. The relationship also differs from country to country. High uncertainty about long-run inflation is associated with a significant positive shift in inflation for Canada, Germany, and Japan. High uncertainty about short-run inflation is associated with a significant positive shift in inflation for Germany and USA, and a significant negative shift in inflation for Canada. The modelling approach employed in this paper is empirically supported by various diagnostics including the Vuong test. We also derive the two components of the variance of inflation forecast for a particular forecast horizon. It is found that the inflation uncertainty increases at all horizons in the middle of 1970s and return to the low level in the middle of 1980s.First version received: June 2001/Final version received: October 2003We would like to thank three anonymous referees for many helpful comments and suggestions.     

Free Entry under Uncertainty

When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation and show that the impact of uncertainty will increase the number of firms in an industry. With increased uncertainty, the risk premium of the marginal buyer increases by more than the risk premium of the average buyer, so that the price increases by more than the risk premium. When turning to the free entry game, we find that the market generates too many firms.     

Flexible Tropism of the Enterprises＇ Organization in Uncertain Competitive Environment

With the rapid development of the computer network, communication technology and the economic globalization, the competition environment faced by the enterprises has been more and more complicated. While the interactive competition becomes more and more fierce, it has been more and more difficult for enterprises to keep sustainable advantages in competition. In this paper the author mainly discusses the severe challenge of the new competition conditions to the traditional hierarchical structure and the reason why flexible organization will be the inevitable strategy selection of the enterprises.
