This paper studies the spatial random effects and spatial fixed effects model. The model includes a Cliff and Ord type spatial lag of the dependent variable as well as a spatially lagged one-way error component structure, accounting for both heterogeneity and spatial correlation across units. We...

We consider a nonparametric test for the null of seasonal unit roots in quarterly time series that builds on the RUR (records unit root) test by Aparicio, Escribano, and Sipols. We find that the test concept is more promising than a formalization of visual aids such as plots by quarter. In order...

This paper presents results concerning the performance of both single equation and system panel cointegration tests and estimators. The study considers the tests developed in Pedroni (1999, 2004), Westerlund (2005), Larsson, Lyhagen, and Löthgren (2001) and Breitung (2005); and the estimators...

Using data from the Vienna Stock Exchange we investigate three different types of consumption based capital asset pricing models: the well known two state model of Mehra and Prescott, the model of Rietz, which includes also a crash state, and an own four state model. The aim of this Vienna Stock...

In this paper we take up a model of Okada (1996) to describe the possibility of collective cooperation in a n-person Prisoner's Dilemma game by means of institutional arrangements. In addition, we introduce the possibility to corrupt the institutional authority by paying him some positive...

We consider the case in which the opening up of an economy to migration results in departure of skilled workers. We point out that while the possibility of migration changes the set of employment opportunities, it also affects the structure of incentives: Higher returns to skills in the foreign...

Empirical studies have emphasized three important factors in firm-labor relationships: (a) organization costs of workers, (b) management opposition against workers' organizing drives, (c) the possibility of productivity enhancing effects due to voice/response reasons. In this paper the interplay...

We demonstrate how altruism can flourish in a population of nonaltruists. We assume that each individual plays a one-shot prisoner's dilemma game with his or her sibling and that the probability than an individual survives to reproduce is proportional to his or her payoff in this game. We model...

This paper develops a Bertrand Price Competition model with differentiated goods in which export subsidies are compared to exchange rate depreciation as different government policies for promoting exports. National governments may wish to help domestic firms to expand market shares in profitable...
