Directed technical change, the elasticity of substitution and wage inequality in developing countries
نویسنده
چکیده
We develop a model of endogenous skill-biased technical change in developing countries. The model reconciles wildly dispersed existing estimates of the elasticity of substitution between more and less educated workers. It also produces an estimating equation for the elasticity, which allow us to produce overdue estimates for developing countries. With four types of data, we nd an elasticity of about 2. In a skill-biased technical change framework, this estimate makes sense of what appears to be little or no correlation between relative skill supply and wage inequality.

The effect of wage growth caused by stock market liquidity on income inequality and poverty in developed and developed countries
One of the significant incentives of the investors to enter the capital market is to earn profits and finally increase wealth. However, one of the most important concerns of the investors while investing in the stock market is the liquidity of the stocks. Thus, the high liquidity of the stock market reduces the risk of non-liquidity of the stock, as well as reduces the cost of capital accumulat...
متن کاملWage Inequality in Developing Countries: An Examination of New Economic Geography Theory
The purpose of this study is to investigate the factors affecting the manufacturing industry wage among selected developing countries based on new economic geography theory. More specifically, we use a panel data model to study the spatial structure of wages in 136 countries for the period 1998-2007. The results indicate that this theory provides a good description of the spatial structure of w...
متن کاملAn Impact of Globalization on Gender Wage Inequality: A case Study of Selected Developing Countries
Globalization may have different impacts on the gender wage gap depending on the specialization and trade pattern as well as the socio-economic situation. The main purpose of this paper is to examine an impact of globalization on gender wage inequality. Specifically, the hypothesis is that globalization reduces gender wage gap. For this, we have employed a panel technique for 21 selected develo...
متن کاملWage inequality, technology, and trade
Recent widening of the wage gap between skilled and unskilled workers has been attributed mainly to skill-biased-technical-change and to trade liberalization. This paper examines the effects of the two in a unified model, in which trade and technology adoption are endogenous. The paper has two main results. First, technical progress increases the wage gap in developed and in less developed coun...
متن کاملThe Piketty Transition
We study the effects on inequality of a ”Piketty transition” to zero growth. In a model with a worker-capitalist dichotomy, we show that the relationship between inequality (measured as a ratio of incomes for the two types) and growth is complicated; zero growth can raise or lower inequality, depending on parameters. In particular, the elasticity of substitution between capital and labor in pro...
