In this article we present an endogenous growth model with productive public investment in infrastructure capital. Further, we suppose that the government pays lump-sum transfers to the household and subsidizes private investment. First, we demonstrate that there exists a unique balanced growth...

We derive the quantitative implications of reducing sustained budget deficits (labeled fiscal stabilizations) in the context of a general equilibrium model of innovation-led growth. In the model, innovation comes from entrant firms creating new products and incumbent firms improving own existing...

Uzawaś steady-state growth theorem (Uzawa (1961)) is generalized to a neoclassical economy that uses current output, e. g., to create technical progress or to manufacture intermediates. The difference between aggregate final-good production and these resources is referred to as net output. The...

In industrial economies, firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic...

In this paper we study growth and welfare effects of fiscal policy in an endogenous growth model with public capital and environmental pollution. As to pollution we assume that it is due to aggregate production. Pollution does not have direct effects as concerns production possibilities but it...

We provide a comprehensive survey of the recent literature on the link between productive government expenditure and economic growth. Starting with the seminal paper of Robert Barro (1990) we show that an understanding of the core results of the ensuing contributions can be gained from the study...

We present an endogenous growth model with externalities of capital and elastic labour supply where we allow for public debt and public spending that is welfare enhancing. We analyze effects of different debt policies on stability and how these policies affect long-run growth and welfare. The...
