We use the two-sector specific factors model, which is known from the theory of international trade, in a growth context to describe major trends of long-run economic development. The endogenous technical progress functions establish the link between the agricultural and the manufacturing sector...

As Chari et al. (2007) indicate, many growth theories explaining frictions in real economies are equivalent to a competitive economy, with some exogenous taxes. Using this idea, I developed an accounting method for identifying fundamental causes of economic growth. A two-sector neoclassical...

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...

A prototypical vintage capital model of economic growth is developed, where the decision to replace old technologies with new ones is modeled explicitly. Technological change is investment specific. Depreciation in this environment is an economic , not a physical concept.

I show that in a conventional Ramsey model, between one-fourth and one-half of the global income distribution can be explained by a single factor: The effect of large, persistent differences in national average IQ on the private marginal product of labor. Thus, differences in national average IQ...

This paper explores the effect of policy variability (or frequency of regime switching) on economic growth and welfare. We study a one sector growth model where investment can be subsidized at either a positive rate or not subsidized at all.

In this study an Extended Version of the Solowian growth model is presented and its properties are compared with those of the original model. In the Solowian model the forces behind the growth process are exogenous and disembodied. In the Extended Model technological change is divided into two...

The role that investment-specific technological change played in generating postwar US growth is investigated here. The premise is that the introduction of new, more efficient capital goods is an important source of productivity change, and an attempt is made to disentangle its effects from the...
