We develop a general equilibrium multi-industry model in which firms use external funds to conduct productivity-enhancing R&D. Industries differ in terms of research costs, which lead them to different optimal research expenditures. In the model, more R&D-intensive industries require more...

Economies tend to diversify and then re-specialize as they develop. In an economy with many industries that experience different rates of productivity growth, these "stages of diversification" may obtain if initial conditions are skewed away from the industries that dominate economic structure...

Two issues related to mapping a multi-sector model into a reduced-form value-added model are often neglected: the composition of intermediate goods, and the distinction between the productivity indices for value added and for gross output. We illustrate their significance for growth accounting...

What factors underlie industry differences in research intensity and productivity growth? We develop a multi-sector endogenous growth model allowing for industry-specific parameters in the production functions for output and knowledge, and in consumer preferences. We find that long run industry...

In a multi-industry growth model, firms need external funds for productivity-enhancing R&D, and face financing constraints. The cost of research differs across industries, so financing constraints hinder industry productivity growth unevenly. Equilibrium industry dynamics map into a...

This paper uncovers evidence of s potentially important channel linking financial development to growth: the financing of innovations introduced by entrepreneurs. Using internationally comparable data on European countries, entry and exit in research-intensive industries are found to be...

Do greater potential gains from trade enhance or erode contracting institutions? In an anonymous exchange environment traders can sign a contract, hence agreeing to interact with the assigned partner, or wait till the next match. Any contract can be endorsed (for a payment) by the enforcement...

We develop a multi-sector general equilibrium model in which productivity growth is driven by the generation of knowledge. In the model, firms allocate resources towards the production of goods and the production of new knowledge, in response to industry-specific factors of demand and...
