in this study the trend of technological change and its nature was studied in production of sugar beet in iran by using dual approach. this approach is useful for estimating the demand structure of the input price change and technology status. after estimating the various forms of flexible functions, by selection of translog cost function with cost share equations system is estimated using seem...

Based on a framework proposed by Battese and Coelli (1995), we estimated the stochastic frontier production function for four Chinese industries: building materials, chemicals, machinery and textiles during 1990–1994. The type of technological change is tested and total factor productivity (TFP) growth is calculated for each industry. We found no evidence of technological change in the building...

The rise in income inequality in developing countries after trade liberalization has been a puzzle for trade theory, which predicts the opposite effect. The authors present a model with imported intermediate goods in which the relative wages of skilled labor can rise due to higher imports of inputs or due to skill-biased technological change. The evidence from Peru in the post-liberalization ph...

Medical technology is valuable if the benefits of medical advances exceed the costs. We analyze technological change in five conditions to determine if this is so. In four of the conditions--heart attacks, low-birthweight infants, depression, and cataracts--the estimated benefit of technological change is much greater than the cost. In the fifth condition, breast cancer, costs and benefits are ...
