Heterogeneous time varying transaction costs and asset pricing in international equity markets

In this paper, we examine the time variation in transaction costs relative to excess returns, in a panel consisting of 10 international equity indices over the time period 1984–2005. This is undertaken by extending the consumption CAPM (CCAPM) model proposed by Campbell and Shiller (Rev. Financ. Stud. 1:195–228, 1988) to incorporate time varying proportional transaction costs. We rigorously address both the cross-country heterogeneity in the estimated model and endogeneity. We find strong evidence that suggests transaction costs should be included as an additional explanatory variable in the CCAPM. This leads to the conclusion that transaction costs should be included in asset pricing models as their stochastic process impacts directly on private consumption expenditure.

Technology and obsolescence: A reinterpretation of the specific-factor model of production

We develop a two sector general equilibrium model with a continuum of sector-specific capital goods in each sector, where each capital good represents a particular type of technology. Even without the standard assumptions usually made in the context of specific-factor models, similar results are derived. This framework is used to analyze the impacts of growth and technological change on the degree of obsolescence in each sector. Innovation and an increasing capital stock increase the degree of obsolescence. On the other hand, growth of labor and modernization of existing technologies reduce the stock of obsolete capital.The paper has benefitted from the comments of the seminar participants at Rutgers University, Cornell University, Columbia University, and at the Indian Statistical Institute, Calcutta.

Trade Liberalization,Skill‐linked Intermediate Production and the Two‐sided Wage Gap

Abstract

A rising wage‐gap, almost universally, in the last two decades has contradicted the age‐old conventional wisdom of asymmetric wage movements across nations when trade is liberalized. We offer an explanation that fits well with the emerging trade pattern between the developed and more advanced developing countries like India and Mexico. We argue that a tariff reduction in the South on imports of an intermediate good from the North may raise the wage‐gap in both the North and the South. The price of the intermediate good moving in different directions and different factor‐intensity‐ranking of this good relative to the two different final goods produced in the two countries underlie this result. Rising wage inequality may specially affect the South because educational expenses and infrastructure do not allow ready transformation of the vast masses of unskilled workers into skilled workers. Hence, the policy lesson of the paper seems to be more public effort in arranging for smoother acquisition of human capital by the unskilled.     

Capital mobility and import substitution policies

This paper considers a conventional trade model with intermediate goods and capital mobility. In this framework, raising the barriers to imports tends to carry a country toward high exports. This is a new result and casts serious doubts regarding the proposition that policies of import substitution which characterized much of Latin America in the 1950s are basically inward oriented and tend to carry toward the low import, low export end of the spectrum.     

The Effect of Inequality on Growth: Theory and Evidence from the Indian States

The paper examines the effect of inequality on growth among the subnational states in India. Theoretically, growth of the regional economy is driven by productive public investment in the provision of health and education services financed by a linear output tax, and the optimum tax rate is determined by the median voter. In contrast to existing results, the authors obtain an ambiguous relationship between initial inequality and subsequent economic growth. Analysis of the Indian state‐level data suggests that rural inequality influences growth of total output more than urban inequality, and does so negatively. The indicator of intersectoral inequality is more important in explaining sectoral output growth.
