This paper studies the short-run transmission of foreign shocks in a small open economy with capital controls and a fixed exchange rate. Capital controls alter the transmission of shocks because endogenous changes in the domestic nominal interest rate affect savings and investment decisions. The...

This paper proposes a unifying framework for theories of capital tax competition, and surveys and synthesizes the literature within this framework. The synthesis covers various standard tax competition models, models allowing for leviathan governments and democratic elections, in addition more...

Semi-endogenous models and, to some extent, also Schumpeterian models are based on the assumption of diminishing returns to R&D. This paper shows that the null hypothesis of constant returns to R&D cannot be rejected for the OECD countries.

This paper sets up a dynamic general equilibrium model to study how the composition of technical progress affects the asymptotic speed of convergence. The following questions are addressed: Will endogenizing a fraction of the productivity increases as coming from learning by investing help to...

Corporate tax systems generally maintain a sharp distinction between debt and equity, however, the advent of hybrid instruments has transformed the universe offinancial instruments into a debt-equity continuum and tax systems therefore need to draw lines that distinguish the set of debt...

In many organizations, decisions are taken by unanimity giving each member veto power. We analyze a model of an organization in which members with heterogenous productivity privately contribute to a common good. Under unanimity, the least efficient member imposes her preferred effort choice on...

The rules demarcating debt and equity for tax purposes differ across countries, hence the possibility that a hybrid instrument is treated as equity in one country and debt in another and that a ?rm with foreign investment can combine tax favored dividend income in the home country and tax...

If environmental quality positively affects the productivity of labor in R&D and pollution is caused by the use of a non-renewable resource, it is socially optimal to postpone extraction and to intertemporally adjust R&D effort.
