In an endogenous growth model with public consumption and public investment, we explore the time-consistent optimal choice for two policy instruments: an income tax rate and the split of government spending between consumption and investment. We show that under the time-consistent, Markov...

In an endogenous growth model with public consumption and investment and an elastic labour supply, we explore the time-consistent optimal choice for two policy instruments: an income tax rate and the split of government spending between consumption and investment. We compare the Markovian...

One strand of the literature on endogenous growth concerns models in which pub- lic infrastructure a¤ects the private production process. A puzzle in this literature is that observed public investment-to-output ratios for developed economies tend to fall short of theoretical model-based optimal...

Some concepts associated with the notion of public consumption could be considered as wasteful public expenditures, so that a firstbest analysis would set their level equal to zero every period. However, their ratio to output is significant and rather stable over time in actual economies. In an...

Modelling the accumulation rule evolving public investment is an issue of utmost interest among economists and politicians. The present paper extends the Barro (1990) model of productive government expenditure by considering a time-adapted rule for the public investment/output ratio. The rule...

In an endogenous growth model with human capital accumulation, we discuss the possibility of welfare improving changes on the 1scal policy stance in some actual economies. First, we characterize the extent to which the initial fall in revenues produced by a permanent tax cut can be compensated...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vintage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which...

In dynamic settings with public capital, it is common to assume that the government claims a constant fraction of public investment to total output each period, which is clearly a restrictive assumption. The goal of the paper is twofold: first, to find out a more reasonable rule for public...

This paper tackles the fundamental issue in public finance of wether taxing or subsidizing factor rents. In a one sector endogenous growth model with private and public capital, similar to that in Barro (1990),we find that raising taxes on factors’ income as part of an optimal fiscal policy is...

This paper discusses wether by implementing an environmental tax reform, a government may achieve a double dividend. We consider the simplest endogenous growth model (AK model) and include a negative environmental externality in the utility function. Pollution flow can be reduced by means of...
