Emigration and Wages in Source Countries: A Survey of the Empirical Literature, February 2014, forthcoming, Robert Lucas edited International Handbook on Migration and Economic Development.
Abstract: This chapter summarizes the emerging empirical literature on the effect of emigration on wages in a source country. The evidence can be broadly divided into four categories: (i) case studies, (ii) simulation exercises, (iii) studies using regional variation and finally, (iv) national level studies. Overall, a substantial body of the evidence points towards a strong and positive relationship between emigration and source country wages. Importantly, the effect has been found to be statistically and economically significant. The estimates from the national-level studies across a wide range of countries range from two percent to five and a half percent increase in wages owing to a 10 percent emigrant supply shock. The impact of emigration on wages has important implications in source countries, for wage inequality across schooling groups and for national income distribution between labor and other factors.
Monetary Policy and Bank Lending Rates in Low-Income Countries: Heterogeneous Panel Estimates, May, 2012 (with Peter Moniel, Peter Pedroni, Williams College, and Antonio Spilimbergo, IMF), revise and resubmit, Journal of Development Economics
Abstract: This paper studies the transmission of monetary shocks to lending rates in a large sample of advanced, emerging, and low-income countries. Transmission is measured by the impulse response of bank lending rates to monetary policy shocks. Long-run restrictions are used to identify such shocks. Using a heterogeneous structural panel VAR, we find that there is wide variation in the response of bank lending rates to a monetary policy innovation across countries. Monetary policy shocks are more likely to affect bank lending rates in the theoretically expected direction in countries that have better institutional frameworks, more developed financial structures, and less concentrated banking systems. Low-income countries score poorly along all of these dimensions, and we find that such countries indeed exhibit much weaker transmission of monetary policy shocks to bank lending rates than do advanced and emerging economies.
Three’s Company: Washington, Wall Street and K Street, supplemental appendix, April, 2012 (with Deniz Igan, IMF), (revise and resubmit, Journal of Law and Economics). [Simon Johnson's column on the paper].
Abstract: This paper explores the link between the political influence of the financial industry and financial regulation in the run-up to the global financial crisis. We construct a detailed database documenting the lobbying activities, campaign contributions, and political connections of the financial industry from 1999 to 2006 in the United States. We find strong evidence that spending on lobbying by the financial industry and network connections between lobbyists and the legislators were positively linked to the probability of a legislator changing positions in favor of deregulation. The evidence also suggests that hiring connected lobbyists who had worked for legislators in the past enhanced the effectiveness of lobbying activities.
Dynamics of Firm Lobbying, August, 2013 (with William Kerr, Harvard Business School and William Lincoln, University of Michigan),( NBER Working Paper No. w1757), forthcoming, American Economic Journal, Economic Policy
Abstract: How is economic policy made? In this paper we study a key determinant of the answer to the question: lobbying by firms. Estimating a binary choice model of firm behavior, we find significant evidence for the idea that barriers to entry induce persistence in lobbying. The existence of these costs is further confirmed in studying how firms responded to a particular policy change: the expiration of legislation relating to the H-1B visa. Due to its influence on firm behavior, we argue that this persistence fundamentally changes the environment in which legislation is made.
India's External Sector: Do We Need To Worry? (with C. Rangarajan), Economic and Political Weekly, February 16, 2013
Abstract: The deterioration in India’s current account has led to a series of debates in the policy arena relating to sustainability, the importance of exchange rates in influencing the trade balance, and the role of high and rising inflation. Against this background, this article takes a step back and analyses the performance of the external sector in India since 1990. It estimates the sustainable current deficit to GDP ratio to be 2.3%. Importantly, even to sustain a 2.3% CAD, India would need net capital infl ows of the order of at least $50-70 billion annually over the next five years. Given the uncertainty around both the push factors (e g, rising global risk aversion) as well as the pull factors (slower growth in India) that determine capital flows, attracting such magnitudes of flows could very well be an uphill task.
Has India's Growth Story Withered? Economic and Political Weekly, April 13, 2013
Abstract: This paper analyzes the growth performance in India over the past two decades. We use several statistical and economic methodologies to estimate the growth rate of potential output. The annual growth rate of potential output is estimated for 2011 to be in the range of 7.7-8.2 percent. All the estimation techniques suggest that there was a big boost to potential growth between 2002 and 2007, but since then it has not increased significantly. Based on statistical approaches and conditional on moderate annual growth forecasts of 7-7.5 percent between 2012 and 2014, there is some evidence that the recent decline in growth is likely to be driven by structural factors. Most of the methodologies indicate that output gap continues to be positive, suggesting caution in further loosening the monetary policy stance. Overall, while the Indian growth story may/may not have withered, the evidence does give indications that the growth story may have faltered.
Financial and Distributional Implications of the Food Security Law, Economic and Political Weekly, September 28, 2013.
Abstract: The financial implications of the National Food Security Bill, which has now become law, are going to be huge. This analysis points out that one needs to take into account not only the cost of the food subsidy but also the costs of setting up or running new institutions and bureaucracies, and the costs that are likely to arise if there are political pressures to protect the existing beneficiaries. There are still more imponderables, and the fi nal cost could add up to much more than what is now estimated.
Democracy and Reforms, November, 2012 (with Paola Giuliano, UCLA and Antonio Spilimbergo, IMF) (NBER Working Paper No w18117, IZA DP No. 4032, CEPR DP No. 7194), American Economic Journal: Macroeconomics, 2013, 5(4): 179-204
Abstract: Empirical evidence on the relationship between democracy and economic reforms is scarce, limited to few reforms and countries and for few years. This paper studies the impact of democracy on the adoption of economic reforms using a new dataset on reforms in the financial, capital, public, and banking sectors, product and labor markets, agriculture, and trade for 150 countries over the period 1960?2004. Democracy has a positive and significant impact on the adoption of economic reforms but there is no evidence that economic reforms foster democracy. Our results are robust to the inclusion of a large variety of controls and estimation strategies.
How Effective Is Monetary Transmission in Developing Countries? A Survey of the Empirical Evidence, November, 2012, (with Peter Montiel), (IMF Working Paper No.12/143), Economic Systems, 2013, Elsevier, vol. 37(2), pages 187-216
Abstract: This paper surveys the evidence on the effectiveness of monetary transmission in developing countries. We summarize the arguments for expecting the bank lending channel to be the dominant means of monetary transmission in such countries, and present a simple model that suggests why this channel may be both weak and unreliable under the conditions that usually characterize those economies. Next, we review the empirical methodologies that have been employed in the recent literature to assess monetary policy effectiveness, both in developing countries as well as in industrial and emerging economies, essentially based on vector autoregressions (VARs). It is very hard to come away from this review of the evidence with much confidence in the strength of monetary transmission in developing countries. We distinguish between the “facts on the ground” and “methodological deficiencies” interpretations of the absence of evidence for strong monetary transmission. We suspect, however, that “facts on the ground” are indeed an important part of the story. The fact that a wide range of empirical approaches have failed to yield evidence of effective monetary transmission in developing countries, and that the strongest evidence for effective monetary transmission has arisen for relatively prosperous and more institutionally developed countries such as some central and Eastern European transition economies (at least in the later stages of their transition) and Tunisia, makes us doubt whether methodological shortcomings are the whole story. If this conjecture is correct, the stabilization challenge in developing countries is acute indeed, and identifying the means of enhancing the effectiveness of monetary policy in such countries is an important challenge.
Trade Liberalization and Wage Inequality in India: A Mandated Wage Equation Approach (with Debkusum Das, Delhi University), July, 2012, India Growth and Development Review, 2013, Vol. 6 Issue: 1, pp.113 - 127
Abstract: This paper uses an empirical approach based on the “mandated wage equations” to examine the relationship between trade liberalization and urban manufacturing wages in India. The main result in the paper is that trade reforms have been associated with a rise in the relative wages of medium-skilled workers (defined as having completed secondary schooling). We do not find any evidence for trade reforms to be associated with an increase or decrease in wage inequality between low and high-skilled workers. The results are consistent with the predictions of the Stolper-Samuelson theorem.
Monetary Transmission in Low-Income Countries: Effectiveness and Policy Implications, February, 2012 (with Peter Montiel, Williams College and Antonio Spilimbergo, IMF), IMF Economic Review (2012) 60, 270–302
Abstract: This paper reviews the monetary transmission mechanism in low-income countries (LICs). We use monetary transmission in advanced and emerging markets as a benchmark to identify aspects of the transmission mechanism that may operate differently in LICs. In particular, we focus on the effects of financial market structure on monetary transmission. The weak institutional framework prevalent in LICs drastically reduces the role of securities markets. Consequently, traditional monetary transmission through market interest rates and market-determined asset prices are weak or nonexistent. The exchange rate channel, in turn, tends to be undermined by heavy central bank intervention in the foreign exchange market. The weak institutional framework also has the effect of increasing the cost of bank lending to private firms. Coupled with imperfect competition in the banking sector, this induces banks to maintain chronically high excess reserves and to invest in domestic public bonds or (when possible) in foreign bonds. With the financial system not intermediating funds properly, the bank lending channel also becomes impaired. These factors undermine both the strength and reliability of monetary transmission, which has important implications for the conduct of monetary policy in LICs.The Power of Political voice: Women’s Political Representation and Crime in India, (with Lakshmi Iyer, HBS, Anandi Mani, Warrick, and Petia Topalova, IMF),American Economic Journal, Applied Economics, 2012, 4(4): 165–93
Abstract: Using state-level variation in the timing of political reforms, we find that an increase in female representation in local government induces a large and significant rise in documented crimes against women in India. Our evidence suggests that this increase is good news, as it is driven primarily by greater reporting rather than greater incidence of such crimes. In contrast, we find no increase in crimes against men or gender-neutral crimes. We also examine the effectiveness of alternative forms of political representation: Large scale membership of women in local councils affects crime against them more than their presence in higher-level leadership positions.
Explaining Inflation in India: The Role of Food Prices, (with Devesh Roy, IFPRI), Brookings-NCAER India Policy Forum. Volume 8, 2011-12
Abstract. This paper conducts a forensic examination of inflation in India with a focus on food price inflation, using a disaggregated high-frequency commodity level dataset spanning the last two decades. First, we document stylized facts about the behavior of overall inflation in India. We establish that low inflation has historically been a rare occurrence in the Indian economy in the last two decades; the long-term trend in the inflation rate exhibits a U-shaped pattern with a structural break in the trend in 2000 and an inflection point in 2002. The long-term trend in food inflation has followed a pattern similar to overall inflation. Domestic and international food price inflation rates have been moderately correlated, though there is significant variation across commodities based on their tradability. Furthermore, we find food price inflation to be consistently higher than non-food, quite persistent, and having a significant pass-through to non-food inflation. Further, the price of food relative to non-food co-moves strongly with aggregate inflation rate. Next, we explicitly quantify the contribution of specific commodities to food price inflation. We find that animal source foods (milk, fish), processed food (sugar, edible oils), fruits and vegetables (e.g. onions) and cereals (rice and wheat) are the primary drivers of food price inflation. Finally, we conduct case studies of some of the top contributors to food price inflation. Combining the insights from macro as well as micro analyses, the paper suggests specific policy implications.
Exchange Rates and Wages in an Integrated World, (with Antonio Spilimbergo, IMF), American Economic Journal, Macroeconomics, 3, October, 2011, pp. 1-33
Abstract: We analyze how the pass-through from exchange rate to domestic wages depends on the degree of integration between domestic and foreign labor markets. Using data from 66 countries over the period 1981-2005, we find that the elasticity of domestic wages to real exchange rate is 0.15 after a year for countries with high barriers to external labor mobility, but about 0.40 in countries with low barriers to mobility. The results are robust to the inclusion of various controls, different measures of exchange rates, and concepts of labor market integration. These findings call for including labor mobility in macro models of external adjustment.
A Fistful of Dollars: Lobbying and the Financial Crisis, (with Deniz Igan and Thierry Tressel, IMF) (NBER WP No. w17076), NBER Macroeconomics Annual, 2011, Volume 26
Abstract: Has lobbying by financial institutions contributed to the financial crisis? We use detailed information on financial institutions’ lobbying and mortgage lending to answer this question, and find that lobbying was associated with more risk-taking during 2000-07 and worse outcomes in 2008. Lobbying lenders originated riskier mortgages, securitized at faster intensity, and expanded more. They suffered from higher delinquencies, experienced negative returns during key bank failures, but positive returns with the bailout announcement, and had a higher bailout probability. These findings suggest that lending by politically active lenders played a role in accumulation of risks and thus contributed to the crisis.
Do Interest Groups Affect US Immigration Policy?, (with Giovanni Facchini, Essex and Anna Maria Mayda, Georgetown), Journal of International Economics, 2011, Volume 85, Issue 1, September, pp. 114-128. (supplemental appendix)
Abstract: While anecdotal evidence suggests that interest groups play a key role in shaping immigration policy, there is no systematic empirical analysis of this issue. In this paper, we construct an industry-level dataset for the United States, by combining information on the number of temporary work visas with data on lobbying activity associated with immigration. We find robust evidence that both pro- and anti-immigration interest groups play a statistically significant and economically relevant role in shaping migration across sectors. Barriers to migration are lower in sectors in which business interest groups incur larger lobby expenditures and higher in sectors where labor unions are more important.
Policies, Enforcement, and Customs Evasion: Evidence from India, (with Arvind Subramanian, Peterson Institute for International Economics and Petia Topalova, IMF), Journal of Public Economics, 2008, Vol 92, Pages 1907-1925
Abstract: We examine the effect of tariff policies on evasion of customs duties, in the context of the trade reform in India of the 1990s. By exploiting the variation in tariff rates across time and products, we identify a robust positive elasticity of evasion with respect to tariffs. A second contribution of the paper is to provide some evidence on the impact of enforcement. While we cannot identify the direct impact of enforcement on evasion, we can establish the extent to which enforcement-related factors, such as product characteristics that determine the ease of detection of evasion, affect the evasion elasticity. The results render support to the hypothesis that improvements in enforcement can reduce the responsiveness of evasion to tariffs.
Health Aid and Infant Mortality, (with David Newhouse, World Bank), Journal of Health Economics, 2009, Volume 28, Issue 4, July, Pages 855-872
Abstract: This paper examines the relationship between health aid and infant mortality, using data from 118 countries between 1973 and 2004. Health aid has a beneficial and statistically significant effect on infant mortality: doubling per capita health aid is associated with a 2 percent reduction in the infant mortality rate. For the average country, this implies that increasing per capita health aid by US$1.60 per year is associated with 1.5 fewer infant deaths per thousand births. The estimated effect is small, relative to the 2015 target envisioned by the Millennium Development Goals. It implies that achieving the MDG target through additional health aid alone would require a roughly 15-fold increase in current levels of aid.
Trade Liberalization and Wage Inequality: Evidence from India, (with Utsav Kumar, Conference Board, New York), Review of Development Economics, 2008, Vol. 12, Issue 2, pp. 291-311
Abstract: We evaluate empirically the impact of the dramatic 1991 trade liberalization in India on the industry wage structure. The empirical strategy uses variation in industry wage premiums and trade policy across industries and over time. In contrast to most earlier studies on developing countries, we find a strong, negative, and robust relationship between changes in trade policy and changes in industry wage premiums over time. The results are consistent with liberalization-induced productivity increases at the firm level, which get passed on to industry wages. We also find that trade liberalization has led to decreased wage inequality between skilled and unskilled workers in India. This is consistent with the magnitude of tariff reductions being relatively larger in sectors with a higher proportion of unskilled workers.
Abstract: This paper presents the first econometric study of the effect of emigration on national wages in a source country. I examine empirically the effect of Mexican emigration to the United States on wages in Mexico using data from the Mexican and US censuses from 1970-2000. The main result in the paper is that emigration has a strong and positive effect on Mexican wages. There is also evidence for increasing wage inequality in Mexico due to emigration. Simple welfare calculations based on a labor demand-supply framework suggest that the aggregate welfare loss to Mexico due to emigration is small. However, there is a significant distributional impact between labor and other factors.

Emigration and Brain-Drain: Evidence from the Caribbean, The B.E. Journals in Economic Analysis & Policy, Berkeley Electronic Press, 2007, Vol 7, Issue 1 (Topics), Article 24, covered in the BBC.
Abstract: This paper quantifies the magnitude and nature of migration flows from the Caribbean and estimates their costs and benefits. The Caribbean countries have lost 10?40 percent of their labor force due to emigration to OECD member countries. The migration rates are particularly striking for the high-skilled. Many countries have lost more than 70 percent of their labor force with more than 12 years of completed schooling?among the highest emigration rates in the world. The region is also the world?s largest recipient of remittances as a percent of GDP. Remittances constituted about 13 percent of the region’s GDP in 2002. Simple welfare calculations (under very conservative assumptions of elasticities) suggest that the losses due to high-skill migration (ceteris paribus) outweigh the official remittances to the Caribbean region.
Spillover Effects of Exchange Rates: A Study of the Renminbi , October, 2013 (with Aaditya Mattoo, World Bank and Arvind Subramanian, Peterson Institute), World Bank Policy Research Working Paper No. 5989, (submitted), [Wall Street Journal column on the paper]
Abstract: This paper estimates the impact of China’s exchange rate changes on exports of competitor countries in third markets, which we call the “spillover effect”. We use recent theory to develop an identification strategy in which competition between China and its developing country competitors in specific products and destinations plays a key role. We exploit the variation—afforded by disaggregated trade data—across exporters, importers, product, and time to estimate this spillover effect. We find robust evidence of a statistically and quantitatively significant spillover effect. Our estimates suggest that a 10 percent appreciation of China’s real exchange rate boosts on average a developing country’s exports of a typical 4-digit HS product category to third markets by about 1.5-2 percent. The magnitude of the spillover effect varies systematically with product characteristics as implied by theory.
How Does Trade Evolve in the Aftermath of Financial Crises?, March, 2012 (with Abdul Abiad and Petia Topalova, IMF), (IMF Working Paper No. 11/3), (submitted)
Abstract: We analyze trade dynamics following past episodes of financial crises. Using an augmented gravity model and 179 crisis episodes from 1970-2009, we find that there is a sharp decline in a country’s imports in the year following a crisis—19 percent, on average—and this decline is persistent, with imports recovering to their gravity-predicted levels only after 10 years. In contrast, exports of the crisis country are not adversely affected, and they remain close to the predicted level in both the short and medium-term.
Protection for Free? An Analysis of U.S. Tariff Suspensions, December, 2013 (with Rod Ludema and Anna Maria Mayda, Georgetown University),(CEPR Discussion Paper No. 7926 ) (submitted)
Abstract: This paper studies the political influence of individual firms on Congressional decisions to suspend tariffs on U.S. imports of intermediate goods. We develop a model in which firms influence the government by transmitting information about the value of protection, using verbal messages and lobbying expenditures. We estimate our model using firm-level data on tariff suspension bills and lobbying expenditures from 1999-2006 and find that indeed verbal opposition by import-competing firms, even without lobbying expenditures, significantly reduces the probability of a suspension being granted. We further find that lobbying expenditures by proponent and opponent firms sway this probability in opposite directions. The effect of verbal opposition is substantially larger than that of both opponent and proponent spending, which implies that either verbal opposition conveys more information or that the government is biased in favor of opponents. Under reasonable assumptions, we find government preferences to be biased in favor of opponents.
