The paper deals with the search for optimal slack grade conditions. The evaluation of the optimal slack grade takes into account the relationship be-tween slack and organizational performance and efficiency measures of re-source allocation. Organization and behavioural theory deliver some...

It is well known that the rock-paper-scissors game has no pure saddle point. Weshow that this holds more generally: A symmetric two-player zero-sum game hasa pure saddle point if and only if it is not a generalized rock-paper-scissors game.Moreover, we show that every finite symmetric...

We show that for many classes of symmetric two-player games, the simple decision rule \imitate-the-best" can hardly be beaten by any other decision rule. Weprovide necessary and sufficient conditions for imitation to be unbeatable and showthat it can only be beaten by much in games that are of...

Sick-pay is a common provision in labor contracts. It insures workersagainst a sudden loss of income due to unexpected absences andhelps them smooth consumption. Therefore, many governments findsick-pay socially desirable and choose to mandate its provision. Butsick-pay is not without its...

In this paper we model the adjustment process of European Union Allowance(EUA) prices to the releases of announcements at high-frequency controlling forintraday periodicity, volatility clustering and volatility persistence. We ¯nd thatthe high-frequency EUA price dynamics are very well captured...

In a neoclassical economy with endogenous capital- and labor-augmentingtechnical change the steady-state growth rate of output per worker is shown to increasein the elasticity of substitution between capital and labor. This conrms theassessment of Klump and de La Grandville (2000) that the...

In this paper, we revisit the association between happiness and inequality. We argue that the perceived fairness of the income generation process affects this association. Building on a two-period model of individual life-time utility maximization, we predict that persons with higher perceived...

Individuals exhibit a randomization preference if they prefer random mix-tures of two bets to each of the involved bets. Such preferences provide thefoundation of various models of uncertainty aversion. However, it has to ourknowledge not been empirically investigated whether uncertainty-averse...

An analytical framework is developed to study the repercussions betweenendogenous capital- and labor-saving technical change and population aging.Following an intuition often attributed to Hicks (1932), I ask whether and howpopulation aging aects the relative scarcity of factors of production,...

This paper deals with the modeling of the relationship of European Union Al-lowance spot- and futures-prices within the second commitment period of the Eu-ropean Union Emission Trading Scheme. Based on high frequency data, we analyzecausality in the ¯rst and the second conditional moments. To...
