This paper examines international cooperation on technological development as an alternative to international cooperation on GHG emission reductions. It is assumed that when countries cooperate they coordinate their investments so as to minimize the agreement costs of controlling emissions and...

The present paper provides an overview of literature on the shift to services. It follows the three dimensions of structural change - final demand, the inter-industry division of labor and inter-industry productivity differences. It first looks at the ?classics?, however (Fisher (1935), Clark...

We empirically study the dynamics of R&D productivity by firm size over an industry's life cycle. To do this, we examine the relationship between R&D expenditures, firm size, and new product introductions at the firm level in the personal computer industry. In general, we find the following. (1)...

How can the world reach herd immunity against COVID-19 before the second anniversary of the pandemic, or March 2022? A study of vaccine demand and supply answers this question. A target of vaccinating 60 percent of the population in each country by March 2022 is likely sufficient to achieve...

This work studies the processes of growth of the worlds top 150 pharmaceutical firms, on the grounds of an original database which also allows disaggregate analysis at the level of single therapeutic classes and chemical entities. Our findings show that the industry - whose long - term evolution...

Using patent citation data for the U.S., we test whether knowledge spillovers in biotechnology are sensitive to distance, and whether that sensitivity has changed over time. Controlling for self-citation by inventor, assignee and examiner, cohort-based regression analysis shows that physical...

Many new technologies exhibit clear generational changes. The empirical literature on technology diffusion traditionally analyses the spread of new technologies generically. We use data from the mobile phone industry, where first-generation (1G) and second-generation technologies (2G) can be...

This paper provides a theory of quot;family network,quot; in contrast to quot;local externalities,quot; to explain the geographic concentration of industry. For many industries, one most important source of entrants is spinoffs, who typically locate near parent firms and benefit from knowledge...

How should multilateral trade policy be designed in a world in which countries differ in terms of market access and technology, and firms with market power differ in terms of productivity? We answer this question in a model of monopolistic competition in which variable markups increasing in firm...
