On economics and business ethics

Economics has an impoverished view of virtuous human behaviour in general, and corporate social responsibility in particular. We claim that this is due to a particular, albeit currently dominant approach to economics. This approach focuses on the pursuit of wealth through efficient allocation of scarce resources by 'rational' utility-maximizing economic agents and institutions, such as markets, firms and states, in the exclusive pursuit of 'efficiency'. This results in an ethic-free and often inimical approach to virtuous behaviour. However, a different approach to economics, which focuses on sustainable global resource creation and allocation, asserts virtuous responsible behaviour to be part and parcel of economic analysis and performance.     

Testing for Regime Changes in Greek Sovereign Debt Crisis

This paper examines whether the efficiency market hypothesis for the Greek sovereign debt holds. As in Blanco et al. (2005) we test the theoretical equivalence of credit default swap (CDS) and spreads that dictates a CI relationship between the two. The main innovation of the present analysis is the use of a threshold vector error-correction (TVECM) model, thus allowing thresholds within the sample covering the period 1990 to 2010. Moreover, by employing this methodology we are able to evaluate the degree and dynamics of transaction costs resulting from various events due to external market imperfections but also domestic factors. The main hypothesis we test is to what extent spreads and CDS are indeed integrated that may result in an efficient and integrated segniorage capital market. Our findings support the gradual integration hypothesis. We find that spreads and CDS are cointegrated, though threshold effects are also revealed in terms of events that have impacted on markets.     

European financial crisis and bank productivity: evidence from Eastern European Countries

The paper examines the productivity levels of the largest banks operating in the Eastern European countries over the period of the ongoing European financial crisis. Specifically, the analysis covers the periods of U.S. subprime crisis, the global financial crisis and the sovereign debt crisis. By adopting a fully nonparametric framework, it provides a probabilistic version of a directional input-oriented Malmquist productivity index alongside with its main decomposition. The results from the analysis suggest that banks have faced a deterioration of their productivity levels between the examined periods. It is evident that during the initiation of European sovereign debt crisis, the banks have weakened their ability to utilize efficiently their inputs of production and their ability to realize scale economies.     

Corporate retained earnings and personal sector saving: a test of the life-cycle hypothesis of saving

The dynamic personal saving function proposed by Swamy (1968) nests in a common framework, the life-cycle hypothesis (LCH) and the Houthakker-Taylor (1970) model of saving. Having accounted for a limitation of the generality of the Swamy result, which regards the role of corporate retention in the two models, the Swamy framework is used to test the LCH implication of perfect substitutability between personal saving and corporate retained earnings using UK data for the 1951–83 period. The empirical results cast doubt on the perfect substitution hypothesis.
