Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties,...

This paper presents a single unified framework that integrates the theoretical literature on Schumpeterian endogenous growth and major strands of the empirical literatures on R&D, productivity growth, and productivity convergence. Starting from a structural model of endogenous growth following...

Economies at early stages of development are frequently shaken by large changes in growth rates, whereas advanced economies tend to experience relatively stable growth rates. To explain this pattern, we propose a model of technological diversification. Production makes use of input-varieties...

Internet development holds the promise of transmitting economic value across physical space at zero marginal cost. In such a “weightless economy”, what factors matter for the location of economic activity and thus for economic development? This paper sketches a model of spatial dynamics over...

The ‘deliberative turn’ in democratic theory has generated a wealth of deliberative experiments. The purpose of deliberation as a research technique (as opposed to policymaking or public consultation) is distinctive: to uncover the public’s informed, considered, and collective view on a...

One of the motivations frequently cited by Sen and Nussbaum for moving away from a utility metric towards a capabilities framework is a concern about adaptive preferences or conditioned expectations. If utility is related to the satisfaction of aspirations or expectations, and if these are...

In this paper the author argues that social scientists need to do more to provide policy-relevant research. Rapid technological and economic change raise new issues about how policy should adjust that are not adequately addressed by older and narrower approaches. The author suggests two ways in...

The Lisbon summit of the European Council in March 2000 declared the number of people living in poverty and social exclusion in the European Union to be unacceptable, and called for steps to tackle the issue, beginning with the setting of targets for particular indicators. The targets suggested...
