Attitudes toward risk were measures in 240 households using two methods: an interview method eliciting certainty equivalents and an experimental gambling approach with real payoffs which, at their maximum, exceeded monthly incomes of unskilled laborers. The interview method is subject to...

Invention possibilities are reformulated using research processes which have a cost and different implications for rates and biases of technical change. In the comparative static model a firm has the choice to build a plant of existing design or to improve it by research. The firm maximizes...

This paper presents a way to measure factor saving biases of technical change, or more generally, of efficiency gains with more than two factors of production. The methodology is then applied to the agricultural sectors of the U.S. (1912-1968) and Japan (1893-1962).

We constructed a relatively simple dynamic general equilibrium model with an agricultural and a nonagricultural sector along neoclassical lines. The economy is closed, but it is not too difficult to evaluate how the opening of the economy would affect the conclusions. The model relates technical...

This paper is an attempt to quantify some interaction effects among capital accumulation, population growth and sectoral technical change in economic development. We tried to find a balance in the difficult trade-off just mentioned. We built a simple dynamic general equilibrium model along...
