We study the optimal combination of corporate tax rate and tax base in a model of a small open economy with heterogeneous firms. We show that it is optimal for the small country's government to effectively subsidize capital inputs by granting a tax allowance in excess of the true costs of...

The most fundamental proposition about growth and competition is that there is a tradeoff between static welfare and long-term growth. This paper reconsiders this basic proposition in an increasing product variety endogenous growth model with competitive markets for 'old' innovative products and...

We investigate the impact of incremental trade liberalization in a dynamic model of endogenous growth with heterogeneous firms and costly trade. Growth originates from horizontal specialization and the steady state productivity growth rate is positive. Innovations require costly R&D and are...

This paper introduces competitive markets in the Grossman- Helpman [1991, ch. 3] increasing variety growth model. In this standard model of endogenous growth theory, competition has a negative incentive effect. Accordingly, a larger resource base is required to sustain long run growth. In an...

In the literature on currency and banking crises it has become the standard procedure to distinguish pure currency crises, pure banking crises and combined ('twin') currency and banking crises. We show theoretically and empirically that a similar differentiation should be chosen with regard to...

We analyse the welfare effects of a publicly imposed smoking ban in privately owned places like bars. In an economy where households have heterogenous (positive and negative) attitudes towards smoking bans, bars can use the smoking regime choice as a strategic variable. In doing so, bars may...

We present a simple behavioral model with chartists and fundamentalists and analyze their trading behavior in a floating regime and in a target zone regime. Regarding the floating regime the model replicates the well-known stylized facts like excessive volatility, fat tails, volatility...

We show theoretically and empirically that twin currency and debt crises should be treated as a particular crisis type. Twin currency and debt crises differ from both pure currency and pure debt crises in their determinants, the course of the crises, and their economic consequences. We find that...

In this paper, we derive a modification of a forward-looking Taylor rule, which integrates two variables measuring the uncertainty of inflation and GDP growth forecasts into an otherwise standard New Keynesian model. We show that certainty-equivalence in New Keynesian models is a consequence of...
