We develop a model to rationalize and examine so-called "research bubbles", i.e. research activities based on overoptimistic beliefs about the impact of this research on the economy. Research bubbles occur when researchers selfselect into research activities and the government aggregates the...

We study a two-phase endogenous growth model in which the adoption of a backstop technology (e.g. solar) yields a sustained supply of essential energy inputs previously obtained from exhaustible resources (e.g. oil). Growth is knowledge-driven and the optimal timing of technology switching is...

We analyze the relative growth performance of open economies in a two-country model where different endowments of labor and a natural resource generate asymmetric trade. A resource-rich economy trades resource-based intermediates for final manufacturing goods produced by a resource-poor economy....

Since 1980, the aggregate income of oil-exporting countries relative to that of oil- poor countries has been remarkably constant despite structural gaps in productivity growth rates. This stylized fact is analyzed in a two-country model where resource- poor (Home) and resource-rich (Foreign)...

This paper studies an endogenous growth model with human capital, exhaustible resources, and overlapping generations. Under laissez-faire, higher study time reduces depletion rates by increasing the share of re- sources that present generations are willing to sell to successors. However, selfish...

This paper formalizes international status seeking in a two-country model of endogenous growth: utility of agents in developing countries is affected by consumption gaps with advanced economies. By distorting intertemporal choices, envy tends to revert growth differentials in favor of the...

So-called "uphill capital flows", i.e. flows of physical capital from relatively poor to rich countries, are a new phenomenon with yet unclear impact. We develop a unified framework incorporating economic institutions, human capital and physical capital to study the interaction of international...
