On the monotonicity of the labour-capital ratio in Sraffa's model

Work done in part while visiting (1988–1989) the Department of Mathematics, University of Virginia, Charlottesville, U.S.A. One of the authors (E.

State-led or market-led green revolution? Role of private irrigation investment vis-a-vis local government programs in West Bengal's farm productivity growth

We estimate the role of private investments in irrigation in farm productivity growth in West Bengal, India between 1982 and 95. Using a state-wide farm panel, we find that falling groundwater costs generated significant growth in value added per acre for farms. These resulted from investments in minor irrigation which was stimulated by tenancy registration programs implemented by local governments. This helps account for substantial spillover effects of the tenancy reform on non-tenant farms noted in an earlier study. Hence the West Bengal Green Revolution of the 1980s benefited from complementarity between private investment incentives and state-led institutional reforms.     

Demand for World Bank lending

This paper attempts to quantify the relevance of crisis lending in IBRD and IDA lending commitments. It finds that IBRD and IDA lending commitments are positively related to an increase in debt service payments and inversely related to the level of reserves of the borrowing country. These two variables explain a large part of the variation in IBRD and IDA lending commitments – adjustment lending as well as project lending – not only since the Asian crisis, but also during tranquil times over the last two decades. This finding implies that bridging the financing gap has been an important factor affecting developing countries’ decision to seek financial help from the Bank. While borrowing for servicing debt during a crisis is consistent with the World Bank's goal of poverty reduction and assisting countries without access to financial markets, such borrowing during tranquil times may conflict with these goals.     

Sovereign-Wealth Funds: the institutional dimension

In the recent past, the operations of the capital-rich Sovereign-Wealth Funds (SWFs) went on increasing in the global capital markets. As the global economic crisis that started in 2007 deepened, SWF operations dramatically spurted, leading to further progressive increase in their significance for the global capital markets. For all appearances they are going to be important financial players in the foreseeable future. This article focuses on the basic concept of SWFs, their structure and operations. It attempts to analyze and elucidate on them. Notwithstanding the fact that SWFs are an instrument of enhancing liquidity and financial resource allocation in the international capital market, they managed to become a source of controversies. Consequently they became a source of escalation in financial protectionism in several advanced industrial economies, in particular the USA. The article concludes that this was unwarranted. Recently SWFs have attempted to device an array of best practices to improve the transparency of their global financial operations. These measures are expected to enhance the acceptance of SWFs as well as global recognition of their operations. They would also help in dispelling the negative image that SWFs have held in several advanced industrial economies.

Persistent Inequality

When human capital accumulation generates pecuniary externalities across professions, and capital markets are imperfect, persistent inequality in utility and consumption is inevitable in any steady state. This is true irrespective of the degree of divisibility in investments. However, divisibility (or fineness of occupational structure) has implications for both the multiplicity and Pareto-efficiency of steady states. Indivisibilities generate a continuum of inefficient and efficient steady states with varying per capita income. On the other hand, perfect divisibility typically implies the existence of a unique steady state distribution which is Pareto-efficient.

Conditional cash transfers and female schooling: the impact of the female school stipend programme on public school enrolments in Punjab,Pakistan

Instead of mean-tested Conditional Cash Transfer (CCT) programmes, some countries have implemented gender-targeted CCTs to explicitly address intra-household disparities in human capital investments. This study focuses on addressing the direct impact of a female school stipend programme in Punjab, Pakistan – Did the intervention increase female enrolment in public schools? To address this question, we draw upon data from the provincial school censuses 2003 and 2005. We estimate the net growth in female enrolments in grade 6–8 in stipend eligible schools. Impact evaluation analysis, including difference-and-difference (DD), triple differencing (DDD) and regression-discontinuity design (RDD), indicate a modest but statistically significant impact of the intervention. The preferred estimator derived from a combination of DDD and RDD empirical strategies suggests that the average programme impact between 2003 and 2005 was an increase of six female students per school in terms of absolute change and an increase of 9% in female enrolment in terms of relative change. A triangulation effort is also undertaken using two rounds of a nationally representative household survey before and after the intervention. Even though the surveys are not representative at the sub-provincial level, the results corroborate evidence of the impact using school census data.     

Bargaining and efficiency in networks

We study an infinite horizon game in which pairs of players connected in a network are randomly matched to bargain over a unit surplus. Players who reach agreement are removed from the network without replacement. The global logic of efficient matchings and the local nature of bargaining, in combination with the irreversible exit of player pairs following agreements, create severe hurdles to the attainment of efficiency in equilibrium. For many networks all Markov perfect equilibria of the bargaining game are inefficient, even as players become patient. We investigate how incentives need to be structured in order to achieve efficiency via subgame perfect, but non-Markovian, equilibria. The analysis extends to an alternative model in which individual players are selected according to some probability distribution, and a chosen player can select a neighbor with whom to bargain.     

Repositioning the Chinese economy on the global economic stage

A tectonic shift in the global economic prowess became obvious around the turn of the last century. Three decades of macroeconomic reforms, sustained growth and global integration have turned China into a future economic power of global magnitude, with unmatched breadth of resources and a robust manufacturing sector. Significance of the Chinese economy has radically increased and it has traversed from the periphery of the global economy to the core. For all appearances, this progress is likely to continue in the foreseeable future. China has grown to be the fourth largest economy in the world in a short time span and the third largest trader. Events like dawning of an economic superpower occur once in several generations. China is endeavoring to make a new niche for itself in the global economy as well as formulate a new role.
