The dynamics of Central European equity market comovements

This paper examines short-term and long-term comovements between developed European Union (EU) stock markets and those of three Central European (CE) countries which recently joined the EU. Dynamic cointegration and principal components methods are applied, in addition to static tests. While we find no evidence of cointegration for the period July 1995–February 2005 as a whole, dynamic tests reveal alternating period of cointegration disrupted by episodes dominated by short-term domestic factors. Principal components analysis reveals that a stable factor explains a large proportion of return variances. Ultimately, despite the decade-long process of alignment by CE countries with the EU, evidence of steadily increasing convergence of equity markets is lacking.     

Corporate disclosure, cost of capital and reputation: Evidence from finance directors

The majority view of the executives interviewed is that disclosure reduces the cost of equity up to the point at which a good-practice level of communication has been reached, after which there is little further effect. Greater disclosure to rating agencies and lenders reduces the cost of debt. Attitudes towards more mandatory disclosure are mostly negative. The main perceived cost of disclosure is creating the information. The main benefits are promotion of a reputation for openness and of shareholder confidence, not a lower cost of capital. We suggest that a reputation for openness is valued because it enhances the company's overall reputation, which brings commercial benefits.     

A Note on the Identification of Dynamic Economic Models with Generalized Shock Processes

Dynamic stochastic general equilibrium (DSGE) models with generalized shock processes, such as shock processes which follow a vector autoregression (VAR), have been an active area of research in recent years. Unfortunately, the structural parameters governing DSGE models are not identified when the driving process behind the model follows an unrestricted VAR. This finding implies that parameter estimates derived from recent attempts to estimate DSGE models with generalized driving processes should be treated with caution, and that there always exists a tradeoff between identification and the risk of model misspecification. However, these results also make it easier to address the issue of model misspecification by making it computationally easier to check the validity of cross‐equation restrictions.     

Nachhaltiges Marketing im Schweizer Detailhandel: Das Beispiel Migros

Zusammenfassung  Wird das Thema Nachhaltigkeit vom Marketing mit allen seinen Aspekten aufgegriffen, hat das Auswirkungen auf die gesamte Wertsch?pfungskette. Die Schweizer Einzelhandelskette Migros begann bereits im Jahr 1973 damit ihren Kunden Produkte aus integrierter Produktion anzubieten. L?ngst ist daraus ein umfassendes nachhaltiges Konzept entstanden, dessen Kern ein eigenes Label dokumentiert. Somit gelingt es der Migros die drei zentralen Aspekte des nachhaltigen Handelns — ?kologische, soziale und ?konomische Dimensionen — umzusetzen.     

Rousseau's notion of envy: A comparison with modern economic theory

Abstract

The concept of envy is present both in Rousseau's economic philosophy and in modern economic theory. This paper compares these different uses of the concept and studies the relevance of the definition of envy adopted on each side, taking into account what is at stake when a notion of envy is introduced. It will be shown that Rousseau's envy cannot be expressed by modern conceptions of envy. Nevertheless, it enlightens the debate between the two competing notions of envy present in modern economic theory, revealing that the existence of envy questions the notion of self-interest.     

The effect of pro-environmental attitudes and eco-labelling information on green purchasing decisions in Australia

The main purpose of this study is to measure the effects of pro-environmental attitudes, knowledge, and eco-labeling information on green purchasing decisions. Data were collected from 400 undergraduate students studying at an Australian University. The findings suggest that pro-environmental attitude and eco-labeling information significantly affect green purchasing decisions. Eco-labeling, however, plays a more significant role in influencing green purchasing decisions. Finally, implications and suggestions for future research are discussed.
