We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

The Clean Development Mechanism (CDM) is a project-based carbon trade mechanism that subsidizes the users of climate-friendly technologies and encourages technology transfer. The CDM has provided financial support for a large share of Chinese wind projects since 2002. Using pooled...

The diffusion of innovations is supposed to dissipate inventors' rents. Yet in many documented cases, inventors freely shared knowledge with their competitors. Using a model and case studies, this paper explores why sharing did not eliminate inventors' incentives. Each new technology coexisted...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

Recent innovation literature has documented the benefits of cross-pollination of ideas across a wide set of industries and technology fields in an economy. Industrial and trade policies, by contrast, tend to favor economic specialization through the promotion of selected sectors. In this paper...

In this work we analyse patterns of technological development using patent applications at the United States Patent and Trademark Office (USPTO) over the 1973-2012 period. Our study focuses on the combinations of technological fields within patent documents and their evolution in time, which can...

Critical technologies including artificial intelligence, semiconductors and quantum computing are attracting attention because of their indispensable nature and their role in national security strategies. We compare China, the United States and the European Union in these technologies and their...

This paper investigates the determinants of EPO (European Patent Office) patent applications per capita using a panel of 22 OECD countries with data measured as five-year averages for the period 1980-1999. The patent production function is specified as a partial adjustment model and is estimated...

Firms invest huge amounts into intangible assets. This paper explores to which extent different kinds of intangible assets are conducive to firm-level productivity. Our study contributes to the literature by simultaneously comparing productivity effects of innovative capital, human capital,...
