Capital mobility, skill formation and polarization

We bring in hierarchical education and skill formation within a standard Jonesian specific-factor model of production and trade for a developing economy. There are three types of labor, unskilled, medium skilled and high-skilled. The unskilled can only develop into medium-skilled and medium-skilled into high-skilled. As capital becomes internationally mobile, educational capital gets concentrated in particular types of education. In the process the society gets polarized between the highly educated and the absolutely uneducated.     

The dual nature of public goods and congestion: the role of fiscal policy revisited

Abstract The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption‐based instruments in conjunction with the income tax. An income tax‐financed increase in government spending dominates both lump‐sum and consumption tax‐financing. Replacing the lump‐sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax. These results contrast sharply with the literature, where the consumption tax is generally viewed as the least distortionary source of public finance.     

A competitive general equilibrium model of technology transfer,innovation, and obsolescence

A general equilibrium production model is developed where technologies are embodied in capital goods of different vintages indexed in a continuum. A difference in the extent of existing knowledge determines a wage gap between a developed (north) and a developing region (south). With free flow of technology, relatively backward technologies move to the south. With innovation in the north, a technology cycle is created by which some of the technologies are pushed out of the north into the south. This also tends to widen the wage gap between the regions.     

Privatization and Strategic Mergers across Borders

We present a theoretical model to capture the role of privatization in the incentives for and implications of cross‐border horizontal mergers. Absent any merger incentives in an autarkic equilibrium, we show that a decrease in the degree of privatization will lower the incentives for diversification of international production. The incentives for diversification for any given degree of privatization will fall when the private and public firms are allowed to move sequentially rather than simultaneously. The presence of the public firm also introduces a new source of asymmetry in the incentives for cross‐border mergers: a reduction in the degree of privatization at home will dampen the potential gains from a take‐over of a home firm by a foreign firm but magnify the potential gains from a take‐over of a foreign firm by a home firm.     

A public firm in a model of spatial duopoly with price discrimination

We visit the role of privatization in the location decision of firms in an industry where no firm can produce all varieties demanded. We demonstrate that the Nash equilibrium locations are socially optimal, in the presence of a publicly owned firm, notwithstanding the degree of privatization.     

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.     

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.     

A HEDONIC PRICE INDEX FOR AIRLINE TRAVEL

Our research takes an exhaustive approach to measurement issues in price index construction for the BLS airfare index. We pursue a number of the objectives for dealing with the biases that the 1997 CPI Commission recommended and detail a protocol for data collection and analysis that can be replicated and can be enhanced by availability of additional data sources. We find an upward bias in the BLS airfare index over the period considered. However, because of issues of practicality and implementability of the methods we utilize in our analysis, the goals of the Commission recommendations remain illusive and problematic in being more broadly applied to other components of the CPI.     

A portfolio based theory of excessive foreign borrowing and capital control in a small open economy

We develop a simple model of portfolio choice in a mean variance framework to address the issue of international borrowing and financial crisis. Instead of adverse selection or moral hazard of lending and borrowing activities we emphasise the role of exchange rate movement. Syndicated borrowing by way of internalising the aggregate effect tends to restrict excessive borrowing from external source. However, this may undermine the welfare consequences by further aggravating the extent of risk undertaken in the process. There is a built-in externality in the model that leads to over exposure to foreign currency debt and readily calls for intervention by the government. Government intervention by way of a tax on foreign borrowing may help restrain the amount of external debt and implement the first best.
