Previous research on optimal R&D subsidies has focussed on the long run.This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method.Starting from the steady state under current R&D subsidization in the...

This paper develops a comprehensive endogenous growth framework to determinethe optimal mix of growth policies. The analysis is novel in that we captureimportant elements of the tax-transfer system and fully take into account transitionaldynamics in our numerical analysis. Currently, for...

The output multiplier turns negative before a deficit spending program expires.We show the generality of this unpleasant finding for the standard real business cyclemodel. We then calibrate an extended model for the US and demonstrate how fiscalstimulus slows down economic recovery from...

We set up a neoclassical growth model extended by a corporate sector, aninvestment and finance decision of firms, and a set of taxes on capital income. We provideanalytical dynamic scoring of taxes on corporate income, dividends, capital gains, otherprivate capital income, and depreciation...

We propose a simple and powerful method for determining the transition processin continuous-time DSGE models under Poisson uncertainty numerically. The idea isto transform the system of stochastic dierential equations into a system of functionaldierential equations of the retarded type. We then...

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth (strong scale effect) or the level of per capita income (weak scale effect), with far-reaching policy implications. However, for modern times there is little empirical support for...

This paper theoretically and empirically analyzes the interaction of emigration of highly skilled labor, an economy`s income gap to potential host economies of expatriates, and optimal public infrastructure investment. In a model with endogenous education and R&D investment decisions we show...
