Africa is not only the poorest and most rural continent, it is also the most youthful continent in terms of population. Given the large number of young job seekers that will enter the labor market over the next decade, we need a better understanding of rural non-farm entrepreneurship,...

Rapid technological progress in artificial intelligence (AI) has been predicted to lead to mass unemployment, rising inequality, and higher productivity growth through automation. In this paper we critically re-assess these predictions by (i) surveying the recent literature and (ii)...

Using comprehensive data for German establishments (1999-2008), we estimate plant-level production functions to analyze if "cultural diversity" affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate regional labor force where the plant...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

"We present a dynamic two-region model with overlapping generations. There are two types of public expenditure, education and infrastructure funding, and governments decide optimally on budget size (tax rate) and its allocation across the two outlays. Productivity of government infrastructure...

We use disaggregated data on Chilean plants, and the Chilean input-output table to examine the impact of agglomeration spillovers on total factor productivity (TFP). In common with previous studies, we find evidence of intra-industry spillovers, but no evidence of cross-industry spillovers in...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

We review Baumol's typology of productive, unproductive and destructive entrepreneurship. We argue that the typology is relevant for explaining the secular decline in business dynamics. To the existing explanations for this decline, we put forward the thesis that entrepreneurship has become less...

In "The Race between Man and Machine: Implications of Technology for Growth, Factor Shares, and Employment," Acemoglu and Restrepo (2018b) combine the task-based model of the labor market with an endogenous growth model to model the economic consequences of artificial intelligence (AI). This...

In this paper, we describe the historical co-evolution of innovation and economic growth in Germany since 1871. The country's rise as an industrial power in the late 19th century, through its innovation and entrepreneurial performance, is contrasted with the post-World War II period. This latter...
