A simple semi-endogenous growth model is employed to show that optimal subsidization of both R&D and capital costs is independent of the distribution of R&D skills in the workforce. This holds despite the empirically supported fact that a higher R&D subsidy rate raises wages of R&D workers.

This paper characterizes the optimal time path of R&D and capital subsidization. Starting from the steady state under current R&D subsidization in the US, the R&D subsidy should significantly jump upwards and then slightly decrease over time. There is a small loss in welfare, however, from...

We construct a simple model where political elites may block technological and institutional development, because of a ‘political replacement effect.’ Innovations often erode elites’ incumbency advantage, increasing the likelihood that they will be replaced. Fearing replacement, political...

This work is focused on identifying the relationship an economic system and its policies have with the environment. The biosphere is chosen in particular as object of analysis but this can be extended by means of an ecosystem recursive properties. The common factor involved in the relationship...

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...

Does redistribution increase inequality? Is inequality harmfiil for growth? Both questions have recently been addressed in a number of single-tax models. In this paper, I examine the relationship between policy, growth and inequality when income and wealth can be taxed at different rates. In the...
