Human capital, inequality, endogenous growth and educational subsidy: A theoretical analysis

This paper develops an endogenous growth model with dualism in human capital accumulation of two types of individuals. The government imposes a proportional income tax on rich individuals and uses the tax revenue to finance the educational subsidy given to poor individuals. We find out the properties of the optimal tax financed educational subsidy policy in the semi-stationary equilibrium of the model using the technique of Stackelberg differential game.     

FROM THE CLASSICAL ECONOMISTS TO EMPIRICISTS: A REVIEW OF THE TERMS OF TRADE CONTROVERSY

Contrary to the classical position, the works of Prebisch and Singer in the middle of the last century launched the controversial hypothesis of a long-term decline in the terms of trade of primary products vis-á-vis manufactured goods and a corresponding decline in the terms of trade of developing countries vis-á-vis advanced ones. The present study traces the origin and evolution of the hypothesis and reviews the related statistical debate. It also reviews the theoretical support for the Prebisch–Singer hypothesis. It is an exercise in the history of economic thought to trace how the controversies surrounding the terms of trade have evolved over time, specifically noting that, with the development of the field of econometrics, the central thesis of the argument got lost somewhere in the realm of hi-tech statistical debates.     

Foreign direct investment and growth in India: a cointegration approach

The two-way link between foreign direct investment and growth for India is explored using a structural cointegration model with vector error correction mechanism. The existence of two cointegrating vectors between GDP, FDI, the unit labour cost and the share of import duty in tax revenue is found, which captures the long run relationship between FDI and GDP. A parsimonious vector error correction model (VECM) is then estimated to find the short run dynamics of FDI and growth. Our VECM model reveals three important features: (a) GDP in India is not Granger caused by FDI; the causality runs more from GDP to FDI; (b) trade liberalization policy of the Indian government had some positive short run impact on the FDI flow; and (c) FDI tends to lower the unit labour cost suggesting that FDI in India is labour displacing.     

Asset price volatility in a nonconvex general equilibrium model

Summary. Asset prices and returns are known to vary significantly more than␣output or aggregate consumption growth, and an order of magnitude in excess of what is justified by innovations to fundamentals. We study excess price volatility in a lifecycle economy with two assets (claims on capital and␣a public debt bubble), heterogeneous agents, and increasing returns to financial intermediation. We show that a relatively modest nonconvexity generates a set valued equilibrium correspondence in asset prices, with two␣stable branches. Price volatility is the outcome of an equilibrium selection mechanism, which mixes adaptive learning with “noise”, and alternates stochastically between the two stable branches of the price correspondence.

A Theoretical Framework for Understanding Transnational Public Goods (TPGs) to Upgrade Environmental Quality

In recent years, there has been an increase in awareness of trans-boundary pollution that places environmental assets at risk both globally and regionally. Globally, manmade pollutants have degraded the stratospheric ozone shield, the oceans, the atmosphere and the biodiversity of the planet. Regionally, these pollutants have harmed aquifers, rivers, lakes, soils and forests. Harmful effects of acid rains, greenhouse gasses, and thin ozone shield are not concentrated within political boundaries of a country, thus jeopardizing the well-being of people in other countries. These trans-boundary pollution problems—termed as Transnational Public Goods (TPGs)—often share two common features: strategic interactions among nations and public good properties. This paper applies the theory of voluntary provisions of TPGs to the behavior of nations to curb chloro-fluoro-carbon emissions that, in large part, preceded the ratification and institution of the Montreal Protocol on substances that deplete the ozone layer.

     

Foreign Capital Flows,Uncertainties of Exchange Rates and Central Bank Independence: Implications for Emerging Economies

Utilizing time series data for a panel of 22 emerging countries and applying Granger causality tests, this paper extends the relationship between central bank independence (CBI) and uncertainties of inflation by including the phenomena of exchange rates and foreign capital flows. There are two specific objectives of this investigation. The first objective is to see whether uncertainty of inflation induces volatility of exchange rates, and vice versa, under differing degrees of CBI. The second objective is to explore whether the dynamics of the former relationship influence foreign capital flows in turn and, if so, whether the extent of CBI plays any role in shaping that influence. The period of study spans the years 1968 through 2013. Conditional variances for inflation and exchange rates define proxies for uncertainties of inflation and exchange rates in the empirical analysis. Additionally, annual inflows of foreign direct investment (FDI) provide measures for foreign capital flows in the analysis. Results of causality tests for high and low CBI country subgroups show interesting differences. For the high CBI countries, uncertainty of inflation and uncertainty of exchange rates do not share any causal relationship whatsoever between them. However, a weak link runs from FDI to uncertainties of inflation in the long run. This may be indicative of the disciplined monetary policy and tamed inflation in these countries. Contrastingly, for the low CBI countries, there is strong evidence of causal links running from uncertainties of inflation to uncertainties of exchange rates on the one hand and to FDI flows on the other. In addition, there is indication of a bi-directional causal link between FDI flows and exchange rates for these countries.     

Does shareholder coordination matter? Evidence from private placements

We propose a new role for private investments in public equity (PIPEs) as a mechanism to reduce coordination frictions among existing equity holders. We establish a causal link between the coordination ability of incumbent shareholders and PIPE issuance. This result obtains even after controlling for alternative explanations such as information asymmetry and access to public markets. Improved equity coordination following a private placement leads to favorable debt renegotiations within one year of issuance. Mitigating coordination frictions among shareholders ultimately decreases the odds of firm default in half.     

COSTLY INTERMEDIATION AND THE POVERTY OF NATIONS*

This article has two goals: (i) to reduce the 7‐fold productivity differential required to explain the observed 33‐fold income difference between the richest and poorest countries of the world; and (ii) to explain cross‐country differences in the capital‐output ratio. To achieve the first goal we modify the production function of the standard neoclassical growth model to include public capital whose provision is subject to intermediation costs. For the second goal we distort private investment by introducing credit frictions. The model, quantified using cross‐country data, generates an income gap of 33 with productivity differences of only 3 under the measured variations in public and private capital. The required productivity gap declines even further, to 2.1, when we introduce a home‐production sector. On the second goal, however, credit frictions do a poor job of explaining cross‐country variations in the capital‐output ratio.     

Unification of some multivariate process capability indices for asymmetric specification region

In manufacturing industries, it is often seen that the bilateral specification limits corresponding to a particular quality characteristic are not symmetric with respect to the stipulated target. A unified superstructure of univariate process capability indices was specially designed for processes with asymmetric specification limits. However, as in most of the practical situations a process consists of a number of inter‐related quality characteristics, subsequently, a multivariate analogue of , which is called C_M(u,v), was developed. In the present paper, we study some properties of C_M(u,v) like threshold value and compatibility with the asymmetry in loss function. We also discuss estimation procedures for plug‐in estimators of some of the member indices of C_M(u,v). Finally, the superstructure is applied to a numerical example to supplement the theory developed in this article.     

ENVIRONMENTAL IMPACTS OF TRADE IN INDIA

Abstract

This article aims at contributing to environment trade debate by evaluating the impacts of international trade on emissions of carbon dioxide, sulphur dioxide, and nitrogen oxides for the Indian economy during 90s using Input-Output techniques. The article has constructed an index of pollution terms of trade. Using the Input-Output table of 1991–92 and 1996–97 for India we have computed pollution terms of trade for the content of CO₂, SO₂, and NO _x . Results show that the indices are below 100, indicating that India produces goods that are more environment friendly than goods it imports, thus challenging the pollution haven hypothesis for India. The article has also offered explanations for these results.
