In this paper we analyze the dynamics of an R&D differential game allowing for technological spillovers and sigmoid learning functions of multiproduct oligopolies. We demonstrate how the presence of learning together with spillovers may generate a rich set of outcomes, varying from constant...

In this paper we analyze effects of public debt on the long-run allocation of resources in a basic endogenous growth model with infinitely lived households. The government levies an income tax and issues government bonds to finance unproductive public spending. We demonstrate that in the case of...

In this paper we analyze the so-called AK endogenous growth model with persistent unemployment due to wages rigidities that result from labor market imperfections. We demonstrate that existence of a balanced growth path implies that it is unique or that there exist two balanced growth paths,...

We present an endogenous growth model with human capital and learning by doing. Human capital is not an input factor in the production process of final output but it affects the ability to build up knowledge capital as a by-product of cumulated investment (learning by doing). Human capital is...

In this paper we present empirical facts on oil exploitation and a model that can replicate some of these facts. In particular, we show that the time path of the oil price, on the one hand, and the extraction and discovery rate, on the other hand, seem to follow a U-shaped and an inverted...

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...

This paper presents a model of economic growth with unemployment due to labor market rigidities. The economy consists of a firm that maximizes profits, of a government and of two types of households that maximize inter-temporal utility. One household supplies skilled labor at the first labor...

In this paper we empirically study the relation between public debt and economic growth. We analyze how the public debt to GDP ratio at a certain point in time is correlated with the GDP growth rate in the following period, where we consider a one-year time span, a three-years time interval and...

In this paper we analyze an endogenous growth model in which sustained per capital growth results from investment in public capital and the government is allowed to borrow from the capital market. As to the government behavior, we do not suppose that governments optimize but instead stick to...

The paper presents and estimates an endogenous growth model with public capital. In contrast, however, to recent studies on economic growth and policy, we allow for capital market borrowing by the government. Since the behavior by the government (tax rates, spending and borrowing) does not...
