Is it is or is it ain't my obligation? Regional debt in a fiscal federation
This paper studies the repayment of regional debt in a multiregion economy with a central authority: Who pays the obligation issued by a region? With commitment, a central government will use its taxation power to smooth distortionary taxes across regions. Absent commitment, the central government may be induced to bail out the regional government in order to smooth consumption and distortionary taxes across the regions. We characterize the conditions under which bailouts occur and their welfare implications. The gains to creating a federation are higher when the (government spending) shocks ...

Social insurance and taxation under sequential majority voting and utilitarian regimes
It is often argued that with a positively skewed income distribution (median less than mean) majority voting would result in higher tax rates than maximizing average welfare and, hence, lower aggregate savings. We reexamine this view in a capital accumulation model, in which distorting redistributive taxes provide insurance against idiosyncratic shocks and income distributions evolve endogenously. We find small differences of either sign between the tax rates set by a majority voting and a utilitarian government, for reasonable parametric specifications, despite the fact that model ...

External vs. internal learning-by-doing in an R&D based growth model
In an economy where growth is determined by the interaction of R&D and learning-by-doing (LBD), changes of factors that stimulate either one of these activities affect growth differently than in an economy where growth is determined by either R&D or LBD alone. In particular, when firms anticipate that R&D for new types of goods threatens the future efficiency gains which they derive from LBD, a more efficient learning process or a larger workforce might reduce rather than increase the growth rate on a balanced growth path.

Insulation impossible: fiscal spillovers in a monetary union
This paper studies the effects of monetary policy rules in a monetary union. The focus of the analysis is on the interaction between the fiscal policy of member countries (regions) and the central monetary authority. When capital markets are integrated, the fiscal policy of one country will influence equilibrium wages and interest rates. Thus there are fiscal spillovers within a federation. The magnitude and direction of these spillovers, in particular the presence of a crowding out effect, can be influenced by the choice of monetary policy rules. We find that there does not exist a monetary ...
