This paper decomposes the growth in land occupied by residences in the United States to give the relative contributions of changing demographics versus increases in the land area used by individual households. Between 1976 and 1992 the amount of residential land in the United States grew 47.5%...

With over a billion people in China, the issue of cultivated land conversion is extremely important both in terms of food security and environmental sustainability. This paper investigates the relationship between cultivated land, environment, and food security in China; and seeks to identity the...

We examine the driving forces behind farmers’ decisions to adapt to climate change, and the impact of adaptation on farmers’ food production. We investigate whether there are differences in the food production functions of farm households that adapted and those that did not adapt. We...

Although many of today's ecological, climatic and socio-economic problems seem unprecedented, similar events have occurred in the past. Western Europe's 'middle ages' (circa 11 to 14th century) may be one such case. By the 12th century, medieval Europe had shifted from the subsistence agrarian...

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 is the first empirical framework that explains the phenomenon of fast growth combined with the demographic transition occurring in the United States since 1860. I propose a structural model that unifies those events through the role of education: the key feature is that parental...

I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is en- dogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating...
