We derive integral tests for the existence and absence of arbitrage in a financial market with one risky asset which is either modeled as stochastic exponential of an Itô process or a positive diffusion with Markov switching. In particular, we derive conditions for the existence of the minimal...

The paper investigates how efficiency of business environment and corruption (infirmal payments and state capture) affect the microeconomic perfirmance of firms. The novelty of the paper is to look at these effects in the interaction with the firm ownership. We use firm-level micro data...

With the completion of EMU, tax competition and, more in general, locational competition is high on the EU policy agenda. In contrast to the standard neo-classical reasoning, recent advances in the theory of trade and location have shown that tax competition does not necessarily lead to a race...

Previous theoretical and empirical research has shown that policymakers have an incentive to centralize government activities in order to weaken the com-petitive pressure of fiscal federalism. We propose and test a positive model of fiscal federalism in which centralization is less likely to...

This paper investigates empirically the effect of import diversity on government size and provides evidence for the love of variety effect on government spending described in Hanslin (2008). I argue that crowding out of firms is an important cost of public good provision. However, due to the...
