Agriculture's share of economic activity is known to vary inversely with a country's level of development. This paper examines whether extensions of the neoclassical growth model can account for some important sectoral patterns observed in a current cross-section of countries and in the time...

This paper puts forth a unified theory of growth that captures a number of relevant features of countries’ transitions from stagnant, predominantly rural economies to vibrant, industrialized economies that have been overlooked by the literature. In our theory, increasing variety of consumer...

In an attempt to account for the huge observed disparity in international incomes, several recent papers study models in the spirit of Solow (1960) where the adoptions of better technologies require investments in new equipment. This paper continues this line of research. It describes an economy...

Why isn't the whole world as rich as the United States? Conventional views holds that differences in the share of output invested by countries account for this disparity. Not so, say Stephen Parente and Edward Prescott. In Barriers to Riches, Parente and Prescott argue that differences in Total...

Technology change is modeled as the result of decisions of individuals and groups of individuals to adopt more advanced technologies. The structure is calibrated to the U.S. and postwar Japan growth experiences. Using this calibrated structure we explore how large the disparity in the effective...

This essay develops a theory of the evolution of international income levels. In particular, it augments the Hansen-Prescott theory of economic development with the Parente-Prescott theory of relative efficiencies and shows that the unified theory accounts for the evolution of international...

This article argues that a natural implication of an innovation-based theory of growth is that slow development facilitates the formation of special interest groups. We demonstrate this in a growth model where innovations take the form of new goods and new production processes, and where factor...

This paper examines the effect of agricultural development on a country's overall development and growth experience. In most poor countries, large fractions of land, labor, and other productive resources are devoted to producing food for subsistence needs. This "food problem" can delay a...

The authors introduce home production into the neoclassical growth model and examine its consequences for development economics. They focus on how well differences in policies that distort capital accumulation explain international income differences. In models with home production, such...
