Indoor air pollution (IAP) caused by solid fuel use and or traditional cooking stoves is a global health threat, particularly for women and young children. The WHO World Health Report 2002 estimates that IAP is responsible for 2.7% of the loss of disability adjusted life years (DALYs) worldwide and 3.7% in high mortality developing countries. Despite the magnitude of this problem, social scientists have only recently begun to pay closer attention to this issue and to test strategies for reducing IAP. In this paper, we provide a survey of the current literature on the relationship between indoor air pollution, respiratory health and economic well-being. We then discuss the available evidence on the effectiveness of popular policy prescriptions to reduce IAP within the household.

While millions of dollars are spent on anti-corruption programmes each year, some analysts still maintain that corruption is nothing more than a tax: the process may be unjust or frustrating but, in the end, it provides goods and services to those who value them the most. Corruption may even ‘grease the wheels’ and speed up an all too cumbersome regulatory process. A study on how driving licences are issued in Delhi, India, finds this view highly misleading and shows precisely how corruption can dramatically alter the consequences of a policy.

Kremer, Michael, and Dan Levy. 2008. “Peer Effects and Alcohol Use among College Students.” Journal of Economic Perspectives 22 (3): 189-206. Publisher's VersionAbstract

This paper examines the extent to which college students who drink alcohol influence their peers. We exploit a natural experiment in which students at a large state university were randomly assigned roommates through a lottery system. We find that on average, males assigned to roommates who reported drinking in the year prior to entering college had a Grade Point Average (GPA) one quarter-point lower than those assigned to nondrinking roommates. The effect of initial assignment to a drinking roommate persists into the second year of college and possibly grows. The effect is especially large for students who drank alcohol themselves in the year prior to college. In contrast to the males, females' GPAs do not appear affected by roommates' drinking prior to college. Furthermore, students' college GPA is not significantly affected by roommates' high school grades, admission test scores, or family background. These findings are more consistent with models in which peers change people's preferences than with models in which peers change people's choice sets. Surprisingly, the policy of segregating drinkers by having substance-free housing could potentially lower average GPA in the university.

Field, Erica, and Rohini Pande. 2008. “Repayment Frequency and Default in Microfinance: Evidence From India.” Journal of the European Economic Association 6 (2-3): 501-509. Publisher's VersionAbstract

In stark contrast to bank debt contracts, most micro-finance contracts require that repayments start nearly immediately after loan disbursement and occur weekly thereafter. Even though economic theory suggests that a more flexible repayment schedule would benefit clients and potentially improve their repayment capacity, micro-finance practitioners argue that the fiscal discipline imposed by frequent repayment is critical to preventing loan default. In this paper we use data from a field experiment which randomized client assignment to a weekly or monthly repayment schedule and find no significant effect of type of repayment schedule on client delinquency or default. Our findings suggest that, among micro-finance clients who are willing to borrow at either weekly or monthly repayment schedules, a more flexible schedule can significantly lower transaction costs without increasing client default.

Pande, Rohini, Timothy Besley, and Vijayendra Rao. 2007. “Political Economy on Panchayats in South India.” Economic and Political Weekly. February 2007., 661-667. Publisher's VersionAbstract
Based on a study of some 500 villages in the four southern Indian states of Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, this paper examines how the functioning of the panchayat system mandated by the 73rd amendment to the Constitution has had an impact on the economic
status of villages and the households within them. The study finds that gram panchayats, created by this massive experiment in democratic decentralisation, have had an effect on the delivery of public services, for example, in the targeting of beneficiaries of welfare programmes, but also that positive outcomes are linked to the political elites thrown up by the system.

This report summarizes the findings of an evaluation of a social safety net initiative, the Programme of Advancement Through Health and Education (PATH), which was undertaken by the Government of Jamaica, beginning in 2001. The main objectives of the initiative, which is operated by the Ministry of Labour and Social Security (MLSS), are to achieve better targeting of welfare benefits to the poor and to increase human capital by conditioning receipt of the benefits on participants meeting certain requirements for school attendance and health care visits.

Duflo, Esther, and Rohini Pande. 2007. “Dams.” Quarterly Journal of Economics 122 (2): 601-646. Publisher's VersionAbstract

This paper studies the productivity and distributional effects of large irrigation dams in India. Our instrumental variable estimates exploit the fact that river gradient affects a district's suitability for dams. In districts located downstream from a dam, agricultural production increases, and vulnerability to rainfall shocks declines. In contrast, agricultural production shows an insignificant increase in the district where the dam is located but its volatility increases. Rural poverty declines in downstream districts but increases in the district where the dam is built, suggesting that neither markets nor state institutions have alleviated the adverse distributional impacts of dam construction.

Bond, Phillipe, and Rohini Pande. 2007. “Coordinating Development: Can Income-based Incentive Schemes Eliminate Pareto Inferior Equilibria?.” Journal of Development Economics 83 (2): 368-391. Publisher's VersionAbstract

Individuals' inability to coordinate investment may significantly constrain economic development. In this paper we study a simple investment game characterized by multiple equilibria and ask whether an income-based incentive scheme can uniquely implement the high-investment outcome. A general property of this game is the presence of a crossover-investment point at which an individual's incomes from investment and non-investment are equal. We show that arbitrarily small errors in the government's knowledge of this crossover point can prevent unique implementation of the high-investment outcome. We conclude that informational requirements are likely to severely limit a government's ability to use income-based incentive schemes as a coordination device.

We study the allocation of driver's licenses in India by randomly assigning applicants to one of three groups: bonus (offered a bonus for obtaining a license quickly), lesson (offered free driving lessons), or comparison. Both the bonus and lesson groups are more likely to obtain licenses. However, bonus group members are more likely to make extralegal payments and to obtain licenses without knowing how to drive. All extralegal payments happen through private intermediaries (“agents”). An audit study of agents reveals that they can circumvent procedures such as the driving test. Overall, our results support the view that corruption does not merely reflect transfers from citizens to bureaucrats but distorts allocation.

Chandra, Amitabh, and Douglas Staiger. 2007. “Productivity Spillovers in Health Care: Evidence from the Treatment of Heart Attacks.” Journal of Political Economy 115 (1): 103-140. Publisher's VersionAbstract

A large literature in medicine documents variation across areas in the use of surgical treatments that is unrelated to outcomes. Observers of this phenomenon have invoked “flat of the curve medicine” to explain it and have advocated for reductions in spending in high‐use areas. In contrast, we develop a simple Roy model of patient treatment choice with productivity spillovers that can generate the empirical facts. Our model predicts that high‐use areas will have higher returns to surgery, better outcomes among patients most appropriate for surgery, and worse outcomes among patients least appropriate for surgery, while displaying no relationship between treatment intensity and overall outcomes. Using data on treatments for heart attacks, we find strong empirical support for these and other predictions of our model and reject alternative explanations such as “flat of the curve medicine” or supplier‐induced demand for geographic variation in medical care.

Pande, Rohini. 2007. “Understanding Political Corruption in Low Income Countries.” In: Handbook of Development Economics, T. Schultz and J. Strauss Eds. 2007., 4, 3155-3184. Publisher's VersionAbstract

Building on the large and growing empirical literature on the political behavior of individuals in low income countries this chapter seeks to understand corruption through the lens of political economy -- particularly in terms of the political and economic differences between rich and poor countries. Our focus is on the political behavior of individuals exposed to democratic political institutions. We review the existing literature on the determinants of individual political behavior to ask whether we can understand the choice of political actors to be corrupt and, importantly, of other individuals to permit it, as a rational response to the social or the economic environment they inhabit. We also discuss the implications of this view of corruption for anti-corruption policies.

This paper examines the recent decentralization reforms in Pakistan under General Musharraf. We highlight major aspects of this reform and analyze its evolution in a historical context to better understand potential causes behind this current decentralization. Analyzing the evolution of local government reforms in Pakistan is interesting because each of the three major reform experiments has been instituted at the behest of a non-representative centre using a ‘top down’ approach. Each of these reform experiments is a complementary change to a wider constitutional reengineering strategy devised to further centralization of political power in the hands of the non-representative centre. We argue that the design of the local government reforms in these contexts becomes endogenous to the centralization objectives of the non-representative centre. It is hoped that analyzing the Pakistani experience will help shed light on the positive political economy question of why non-representative regimes have been willing proponents of decentralization to the local level.

In recent years, policy makers have expressed growing concern about Pakistan’s religious schools, which are commonly known as madrasas.1 These concerns have been fueled considerably by reports and articles in the popular press contending that madrasa enrollment is high and increasing. The “rise” is generally attributed to either an increasing preference for religious schooling among families or a lack of other viable schooling options for the household.2 Yet while these theories have widespread currency, none of the reports and articles that we have reviewed have based their analysis on publicly available data sources or established statistical methodologies. Given the importance that is placed on the subject by policy makers in Pakistan and internationally, it is troubling that these theories remain unconfirmed.

Buyer–Seller networks are pervasive in developing economies yet remain relatively understudied. Using primary data on contracts between the largest tractor assembler in Pakistan and its suppliers we find large variations in prices and quantities across suppliers of the same product. Surprisingly, “tied” suppliers – those that choose higher levels of specific investments – receive lower and more unstable orders and lower prices. These results are explained by developing a simple model of flexible specialization under demand uncertainty. A buyer faces multiple suppliers with heterogeneous types to supply customized parts. Specific investments raise surplus within the relationship but lower the seller's flexibility to cater to the outside market. Higher quality suppliers have a greater likelihood of selling outside and so this cost is greater for them. Therefore even if a buyer typically prefers high types, some low type suppliers might be kept as marginal suppliers because of their greater willingness to invest more in buyer-specific assets. Further empirical examination shows that the more tied suppliers are indeed of lower quality.

Levy, Dan, Johanne Boisjoly, Michael Kremer, and Jacque Eccles. 2006. “Empathy or Antipathy? The Impact of Diversity.” American Economic Review 96 (5): 1890-1905. Publisher's VersionAbstract

Mixing across racial and ethnic lines could spur understanding or inflame tensions between groups. We find that white students at a large state university randomly assigned African American roommates in their first year were more likely to endorse affirmative action and view a diverse student body as essential for a high-quality education. They were also more likely to say they have more personal contact with, and interact more comfortably with, members of minority groups. Although sample sizes are too small to provide definitive evidence, these results suggest students become more empathetic with the social groups to which their roommates belong.

Pande, Rohini. 2006. “Profits and Politics: Coordinating Technology Adoption in Agriculture.” Journal of Development Economics, December 2006 81 (2): 299-315.Abstract

This paper examines the political economy of coordination in a simple two-sector model in which individuals' choice of agricultural technology aspects industrialization. We demonstrate the existence of multiple equilibria; the economy is either characterized by the use of a traditional agricultural technology and a low level of industrialization or the use of a mechanized technology and a high level of industrialization. Relative to the traditional technology, the mechanized technology increases output but leaves some population groups worse off. We show that the distributional implications of choosing the mechanized technology restrict the possibility of Pareto-improving coordination by an elected policymaker, even when we allow for income redistribution.

We use household and village survey data from South India to examine who participates in village meetings called by elected local governments, and what effect these meetings have on beneficiary selection for welfare programs. Our main finding is that it is the more disadvantaged social groups who attend village meetings and that holding such meetings improves the targeting of resources towards the neediest groups.
