We analyse how spatial disparities in innovation activities, coupled with migration costs, affect economic geography, growth and regional inequality. We provide conditions for existence and uniqueness of a spatial equilibrium, and for the endogenous emergence of industry clusters. Spatial...

We study the impact of health insurance expansion in the US on health expenditure, longevity growth and welfare in an overlapping generations economy in which individuals purchase health care to lower mortality. We consider three sectors: final goods production; a health care sector, selling...

We utilize a standard endogenous-growth model with knowledge spillovers (the “k-K” model). We characterize the optimal Balanced Growth Path (BGP), and compare it to the path under market competition. In the presence of externalities, markets fail. One way to restore efficiency is to...

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation, and provide a formula to decompose the mechanism. The new insight we provide is that market concentration can be a welfare-relevant feature of market power above and beyond markup...

The objective of this study is to evaluate the different channels in which human capital affects income level and growth and to use a proxy of human capital variable that incorporates quantitative and qualitative aspects of this factor. The human capital proxy that will be used is years of...

Can a transfer of wealth from the US to least developed countries be Pareto improving? We analyze this question in an open-economy innovation-driven growth model, in which the high-income (low-income) country produces innovative (homogenous) goods. We find that wealth redistribution to the...

Growth and business cycles have a long tradition of being studied separately. However, events such as the Great Recession raise concerns that severe downturns may have detrimental implications for growth. If so, what policies may help alleviate such long-lasting effects of large recessions? To...

This paper provides an overview of the recent analytical and empirical literature on middle-income traps. The first part examines the descriptive and statistical evidence on these traps. The second discusses the various arguments that have been put forward to explain the existence, and...

We develop a model that incorporates salient features of growth in modern economies. We combine the expanding-variety growth model through horizontal innovations with a hierarchy of basic and applied research. The former extends the knowledge base, while the latter commercializes it. Two-way...

This paper argues that growth theory needs a more general notion of “regularity” than that of exponential growth. We suggest that paths along which the rate of decline of the growth rate is proportional to the growth rate itself deserve attention. This opens up for considering a richer set...
