This paper studies how the assignment of patents as collateral determines the savings of firms and magnifies the effect of innovative rents on investment in research and development (R&D). We analyse the behaviour of innovative firms that face random and lumpy investment opportunities in R&D....

In neoclassical theory, knowledge generates increasing returns - and therefore growth - because it is a public good that can be costlessly reused once created. In fact, however, much knowledge in the economy is actually tacit and not easily transmitted -and thus not an obvious source of...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

The aim of this article is to extend the traditional Solow model to a small open economy. We focus on the role of the speed of technological progress at the moment of full opening to international capital market. We are primarily interested in two fundamental issue: firstly, what advantages may...

We analyze an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. Long-term dynamics are driven by resource prices, sectoral composition, and directed technical change. We study the balanced growth path and determine stability conditions. Technical...

In this note we show that the standard, loglinear growth regression specification is consistent with one and only one model in the class of stochastic Ramsey models. This model is highly restrictive: it requires a Cobb-Douglas technology and a 100% depreciation rate and it implies that risk does...

We report an intriguing empirical observation. The relationship between corruption and output depends on the economy's degree of openness: in open economies, corruption and GNP per capita are strongly negatively correlated, but in closed economies there is no relationship at all. This stylized...
