Commodity prices are significantly more volatile than prices of industrial products. This extreme price instability establishes a need for futures markets in commodities. The main functions of futures trading being hedging against, and speculation on price fluctuations; and it is hedging, that...

In a simple oligopsonistic model, firms compete for labour through wages and job qualities. We modify the product market model developed by Vandenbosch/Weinberg 1995 and apply it to the job market with jobs being defined by two vertically differentiated non-wage characteristics. Workers differ...

This paper provides simulation evidence concerning some statistical properties of two different approaches to technical efficiency estimation for multiple-output production under noisy conditions: The Ray Frontier Approach (RFA) from Löthgren (1997) DEA+ proposed in Gstach (1996). RFA, unlike...

This article presents an econometric analysis of the maintenance costs for the Austrian railway system. The data contain observations of track maintenance costs from 1998 to 2000. Our analysis identifies the cost driving factors in order to determine estimates of marginal costs, as required by...

This paper estimates a labor demand equation based on the panel data of manufacturing industry in the Central and Eastern European Countries (the Czech Republic, Hungary, Poland, Slovakia, Slovenia, Lithuania, Bulgaria, and Romania) in order to test the effect of domestic factors (wages and...

We discuss the effects of rising shareholder power on distribution and capital accumulation in a Kaleckian model. Increasing shareholder power is associated with decreasing managements’ animal spirits, on the one hand, and increasing dividends distributed to shareholders, on the other hand. In...

The Thesis: Commodity prices are significantly more volatile than prices of industrial products. Production as well as non speculative demand of raw materials are subject to stochastic - sometimes even systematic - fluctuations, which get translated into pronounced price fluctuations by low...

This paper reviews and summarises the results of selected studies on performance gaps between multinational enterprises and their domestic counterparts. Performance gaps arise in such fields as productivity, technology, profitability, wages, skills and growth. While these gaps are often...

The aim of the paper is to give an overview over basic models of Post-Keynesian growth theory. Two major families of growth models are discussed, one developed by Joan Robinson, the other by Michal Kalecki. Both share an independent investment function that depends on income distribution and a...
