This paper works out some of the basic properties of an economy with energy as a factor of production. The economy now consists of streams of energy conversions that direct energy to the production of goods and services. The focus on energy generates a variety of insights. It yields a new...

Economists have long debated the best way to explain the sources of productivity growth. Neoclassical theory and 'new growth' theory both regard investment - broadly defined to include purchases of tangible assets, human capital expenditures, and research and development efforts - as a critical...

Local beer breweries in Burkina Faso absorb a considerable amount of urban woodfuel demand. We assess the woodfuel savings caused by the adoption of improved brewing stoves by these, mostly female owned, small enterprises and estimate the implied welfare effects through the woodfuel market on...

This paper provides technical documentation to a database built up from firm-level sources titled Micro moments database(MMD) that is made available for researchers through Eurostat. The MMD is an internationally harmonized research database of statistical moments collected from linked...

Why is it that adopting new technologies takes so long and costs so much? Clearly, firms do not know all the details necessary to implement a complex technology efficiently; learning these details requires extensive search. However, this explanation has a problem: even limited search may be so...

“Sustainable prosperity” denotes an economy that generates stable and equitable growth for a large and growing middle class. From the 1940s into the 1970s, the United States appeared to be on a trajectory of sustainable prosperity, especially for white-male members of the U.S. labor force....

We study the impact of techies--engineers and other technically trained workers--on firm-level productivity. We first report new facts on the role of techies in the firm by using French administrative data and unique surveys. Techies are STEM-skill intensive and are associated with innovation,...

The determinants of the direction of technical change and their implications for economic growth and economic policy are studied in the one-sector neoclassical growth model of Ramsey, Cass, and Koopmans extended to allow for endogenous capital- and labor-augmenting technical change. We develop a...
