What is different about urbanization in rich and poor countries? Cities in Brazil, China, India and the United States
Chauvin, J.P., et al., 2017. What is different about urbanization in rich and poor countries? Cities in Brazil, China, India and the United States. Journal of Urban Economics , 98 (March 2017) , pp. 17-49. Publisher's VersionAbstract
Are the well-known facts about urbanization in the United States also true for the developing world? We compare American metropolitan areas with analogous geographic units in Brazil, China and India. Both Gibrat’s Law and Zipf’s Law seem to hold as well in Brazil as in the U.S., but China and India look quite different. In Brazil and China, the implications of the spatial equilibrium hypothesis, the central organizing idea of urban economics, are not rejected. The India data, however, repeatedly rejects tests inspired by the spatial equilibrium assumption. One hypothesis is that spatial equilibrium only emerges with economic development, as markets replace social relationships and as human capital spreads more widely. In all four countries there is strong evidence of agglomeration economies and human capital externalities. The correlation between density and earnings is stronger in both China and India than in the U.S., strongest in China. In India the gap between urban and rural wages is huge, but the correlation between city size and earnings is more modest. The cross-sectional relationship between area-level skills and both earnings and area-level growth are also stronger in the developing world than in the U.S. The forces that drive urban success seem similar in the rich and poor world, even if limited migration and difficult housing markets make it harder for a spatial equilibrium to develop.
Bahar, D., 2017. The Middle Productivity Trap: Dynamics of Productivity Dispersion.Abstract
Using a worldwide firm-level panel dataset I document a "U-shaped" relationship between productivity growth and baseline levels within each country and industry. That is, fast productivity growth is concentrated at both ends of the productivity distribution. This result
serves as a potential explanation to two stylized facts documented in the economic literature: the rising productivity dispersion within narrowly defined sectors, and the increasing market share of few yet highly productive firms.

Bahar, D., et al., 2017. The Birth and Growth of New Export Clusters: Which Mechanisms Drive Diversification?.Abstract
Export diversification is associated with economic growth and development. Our paper explores competing mechanisms that mediate the emergence and growth of export products based on their economic relatedness to pre-existing exports. Our innovation is to simultaneously consider supply factors like labor, sourcing and technology; as well as demand factors like industry specific customer-linkages in a global setting. We find that, while technology and workforce similarity explain emergence and growth, pre-existing downstream industries remain a robust predictor of diversification, especially for jump starting new exports in developing countries. Our global stylized fact generalizes Javorcik’s (2004) view that spillovers are more likely in backward linkages.

Bahar, D., 2017. The Hardships of Long Distance Relationships: Time Zone Proximity and Knowledge Transmission within Multinational Firms.Abstract
Using a unique dataset on worldwide multinational corporations with precise location of headquarters and affiliates, I present evidence of a trade-off between distance to the headquarters and the knowledge intensity of the foreign subsidiary’s economic activity, emerging from dynamics related to the proximity-concentration hypothesis. This trade-off is strongly diminished the higher the overlap in working hours between the headquarters and its foreign subsidiary. In order to rule out biases arising from confounding factors, I implement a regression discontinuity framework to show that the economic activity of a foreign subsidiary located just across the time zone line that increases the overlap in working hours with its headquarters is, on average, about one percent higher in the knowledge intensity scale. I find no evidence of the knowledge intensity and distance trade-off weakening when a non-stop flight exists between the headquarters and the foreign subsidiary. The findings suggest that lower barriers to real-time communication within the multinational corporation play important role in the location strategies of multinational corporations.

Frankel, J., 2017. How to Cope with Volatile Commodity Export Prices: Four Proposals.Abstract

Countries that specialize in commodities have in recent years been hit by high volatility in world prices for their exports. This paper suggests four ways that commodity-exporters can make themselves less vulnerable.

(1) Option contracts can be used to hedge against short-term declines in the commodity price without giving up the upside, as Mexico has shown.

(2) Commodity-linked bonds can hedge longer-term risk, and often have a natural ultimate counter-party in multinational corporations that depend on the commodity as an input.

(3) The well-documented pro-cyclicality of fiscal policy among commodity exporters can be reduced by insulating official forecasters against an optimism bias, as Chile has shown.

(4) Monetary policy can be made automatically more counter-cyclical, judged by the criterion of currency appreciation in reaction to positive terms-of-trade shocks, under either of two regimes:   peggers can add the export commodity to a currency basket (CCB, for “Currency-plus-Commodity Basket”) and others can target Nominal Income instead of the CPI.

Halff, A., et al., 2017. Apocalypse Now: Venezuela, Oil and Reconstruction, Columbia University's School of International and Public Affairs. Publisher's VersionAbstract

Venezuela is at a breaking point. The political, economic, financial, social and humanitarian crisis that has gripped the country is intensifying. This unsustainable situation raises several urgent questions: Which path will the embattled OPEC country take out of the current turmoil? What type of political transition lies ahead? What short-term and long-term impact will the crisis have on its ailing oil industry, economy and bond debt? What would be the best and most effective prescription for oil and economic recovery under a new governance regime? To discuss these matters, the Center on Global Energy Policy brought together on June 19, 2017 a group of about 45 experts, including oil industry executives, investment bankers, economists and political scientists from leading think tanks and universities, consultants, and multilateral organization representatives. This note provides some of the highlights from that roundtable discussion, which was held under the Chatham House rule.

Patt, A., et al., 2017. International Emigrant Selection on Occupational Skills.Abstract
We present the first evidence that international emigrant selection on education and earnings materializes through occupational skills. Combining novel data from a representative Mexican task survey with rich individual-level worker data, we find that Mexican migrants to the United States have higher manual skills and lower cognitive skills than non-migrants. Conditional on occupational skills, education and earnings no longer predict migration decisions. Differential labor-market returns to occupational skills explain the observed selection pattern and significantly outperform previously used returns-to-skills measures in predicting migration. Results are persistent over time and hold within narrowly defined regional, sectoral, and occupational labor markets.

Sanctions and Export Deflection: Evidence from Iran
Haidar, J.I., 2017. Sanctions and Export Deflection: Evidence from Iran. Economic Policy , 32 (90) , pp. 319–355. Publisher's VersionAbstract
Do export sanctions cause export deflection? Data on Iranian non-oil exporters between January 2006 and June 2011 shows that two-thirds of these exports were deflected to non-sanctioning countries after sanctions were imposed in 2008, and that at this time aggregate exports actually increased. Exporting firms reduced prices and increased quantities when exporting to a new destination, however, and suffered welfare losses as a result.

Hausmann, R., Santos, M.A. & Obach, J., 2017. Appraising the Economic Potential of Panama: Policy Recommendations for Sustainable and Inclusive Growth.Abstract

This report aims to summarize the main findings of the project as gathered by the three baseline documents, and frame them within a coherent set of policy recommendations that can help Panama to maintain their growth momentum in time and make it more inclusive. Three elements stand out as cornerstones of our proposal:

(i) attracting and retaining qualified human capital;

(ii) maximizing the diffusion of know-how and knowledge spillovers, and

(iii) leveraging on public-private dialog to tackle coordination problems that are hindering economic activity outside the Panama-Colón axis.

Bahar, D., Molina, C.A. & Santos, M.A., 2017. Fool’s Gold: On the Impact of Venezuelan Devaluations in Multinational Stock Prices.Abstract

This paper documents negative cumulative abnormal returns (CARs) to five exchange rate devaluations in Venezuela within the context of stiff exchange controls and large black-market premiums, using daily stock prices for 110 multinationals with Venezuelan subsidiaries. The results suggest evidence of statistically and economically significant negative CARs of up to 2.07% over the ten-day event window. We find consistent results using synthetic controls to causally infer the effect of each devaluation on the stock prices of global firms active in the country at the time of the event. Our results are at odds with the predicaments of the efficient market hypothesis stating that predictable devaluations should not impact stock prices of large multinational companies on the day of the event, and even less so when they happen in small countries. We interpret these results as suggestive indication of market inefficiencies in the process of asset pricing.

Marrazzo, P.M. & Terzi, A., 2017. Wide-reaching Structural Reforms and Growth: A Cross-country Synthetic Control Approach.Abstract

At a time of slow growth in several advanced and emerging countries, calls for more structural reforms are multiplying. However, estimations of the short- and medium-term impact of these reforms on GDP growth remain methodologically problematic and still highly controversial. We contribute to this literature by making a novel use of the non-parametric Synthetic Control Method to estimate the impact of 23 wide-reaching structural reform packages (including both real and financial sector measures) rolled out in 22 countries between 1961 and 2000. Our results suggest that, on average, reforms started having a significant positive effect on GDP per capita only after five years. Ten years after the beginning of a reform wave, GDP per capita was roughly 6 percentage points higher than the synthetic counterfactual scenario. However, average point estimates mask a large heterogeneity of outcomes. Benefits tended to materialise earlier, but overall to be more limited, in advanced economies than in emerging markets. These results are confirmed when we use a parametric dynamic panel fixed effect model to control for the rich dynamics of GDP, and are robust to a variety of alternative specifications, placebo and falsification tests, and to different indicators of reform.

O'Brien, T., Nedelkoska, L. & Frasheri, E., 2017. What is the Binding Constraint to Growth in Albania?, Center for International Development at Harvard University.Abstract

About four years ago, at the onset of CID’s engagement in Albania, the country faced two issues that were threatening its macro-fiscal stability: a skyrocketing public debt and an insolvent, publicly-owned electricity distribution system that was plagued by theft and technical inefficiency. These two interlinked issues constrained both short-term economic growth and the ability of the country to develop new drivers of long-term growth. Over the subsequent years, the government was able to successfully respond to these constraints through a now-concluded IMF program and through a series of reforms in the electricity sector. With these constraints now relaxed, CID saw the need for a new analysis of the current and emerging constraints to growth in Albania. This analysis will guide future research and inform the government and non-government actors on emerging economic issues for prioritization.

While growth has accelerated over the last several years, to over 3% in 2016, this is not a pace that will allow for a rapid convergence of incomes and well-being in Albania with that of developed countries in Europe and elsewhere. This growth diagnostic attempts to identify the binding constraint to sustainably higher economic growth in Albania.

Recognizing that economic growth requires a number of complementary inputs, from roads to human capital to access to finance and many more, this report compares across eight potentially binding constraints using the growth diagnostic methodology to identify which constraint is most binding. This research was conducted throughout 2016, building on prior research conducted by CID and other organizations in Albania. Each constraint discussed in this report is cited by analysts within or outside the country as the biggest problem for growth in Albania. Through the growth diagnostic framework, we are able to evaluate the evidence and show that some constraints are more binding than others.

Despite serious issues in many other areas, we find that the binding constraint to stronger growth in Albania is a lack of productive knowhow. By “knowhow,” we mean the knowledge and skills needed to produce complex goods and services. Albania faces a unique knowhow constraint that is deeply rooted in its closed-off past, and the limited diversification that has taken place in the private sector can, in nearly all cases, be linked to distinct inflows of knowhow. The strongest sources of knowhow inflows into Albania have been through foreign direct investment and immigration, especially returning members of the diaspora who start new businesses or upgrade the productivity of existing businesses.

The evidence also points to particular failings in rule of law in Albania that play an important role in keeping Albania in a low-knowhow equilibrium. Weaknesses in Albania’s rule of law institutions, including frequent policy reversals and corruption in the bureaucracy and judiciary, increase the risk of investments and transaction costs of business. While it is difficult to separate perceptions from reality in this area, both perceptions of weak rule of law and actual rule of law failings appear to play critical roles in constraining more diversified investment in Albania. We find that while existing firms in Albania successfully navigate the rule of law weaknesses, and in some cases benefit from the system, potential new investors are acutely sensitive to rule of law issues.

Frankel, J.A., 2017. The Currency-Plus-Commodity Basket: A Proposal for Exchange Rates in Oil-Exporting Countries to Accommodate Trade Shocks Automatically.Abstract

The paper proposes an exchange rate regime for oil-exporting countries. The goal is to achieve the best of both flexible and fixed exchange rates. The arrangement is designed to deliver monetary policy that counteracts rather than exacerbates the effects of swings in the oil market, while yet offering the day-to-day transparency and predictability of a currency peg. The proposal is to peg the national currency to a basket, but a basket that includes not only the currencies of major trading partners (in particular, the dollar and the euro), but also the export commodity (oil). The plan is called Currency-plus-Commodity Basket (CCB). The paper begins by fleshing out the need for an innovative arrangement that allows accommodation to trade shocks. The analysis provides evidence from six Gulf countries that periods when their currencies were “undervalued”, in the sense that the actual foreign exchange value lay below what it would have been under the CCB proposal, were periods of overheating as reflected in high inflation and of external imbalance as reflected in high balance of payments surpluses. Conversely, periods when the currencies were “overvalued,” in the sense that their foreign exchange value lay above what it would have been under CCB, featured unusually low inflation and low balance of payments. These results are suggestive of the implication that the economy would have been more stable under CCB. The last section of the paper offers a practical blueprint for detailed implementation of the proposal.

Coscia, M., Cheston, T. & Hausmann, R., 2017. Institutions vs. Social Interactions in Driving Economic Convergence: Evidence from Colombia.Abstract

Are regions poor because they have bad institutions or are they poor because they are disconnected from the social channels through which technology diffuses? This paper tests institutional and technological theories of economic convergence by looking at income convergence across Colombian municipalities. We use formal employment and wage data to estimate growth of income per capita at the municipal level. In Colombia, municipalities are organized into 32 departamentos or states. We use cellphone metadata to cluster municipalities into 32 communication clusters, defined as a set of municipalities that are densely connected through phone calls. We show that these two forms of grouping municipalities are very different. We study the effect on municipal income growth of the characteristics of both the state and the communication cluster to which the municipality belongs. We find that belonging to a richer communication cluster accelerates convergence, while belonging to a richer state does not. This result is robust to controlling for state fixed effects when studying the impact of communication clusters and vice versa. The results point to the importance of social interactions rather than formal institutions in the growth process.

Hausmann, R. & Nedelkoska, L., 2017. Welcome Home in a Crisis: Effects of Return Migration on the Non-migrants' Wages and Employment.Abstract

The recent economic depression in Greece hit the population of Albanian migrants in Greece particularly hard, spurring a wave of return migration which increased the Albanian labor force by 5 percent in less than four years, between 2011 and 2014. We study how this return migration affected the employment chances and earnings of Albanians who never migrated. We find positive effects on the wages of low-skilled non-migrants and overall positive effects on employment. The gains partially offset the sharp drop in remittances in the observed period. An important part of the employment gains are concentrated in the agricultural sector, where most return migrants engage in self-employment and entrepreneurship. Businesses run by return migrants seem to pull Albanians from non-participation, unemployment and subsistence agriculture into commercial agriculture.

Neffke, F., 2017. Coworker complementarity.Abstract

How important is working with people who complement one's skills? Using administrative data that record which of 491 educational tracks each worker in Sweden absolved, I quantify the educational fit among coworkers along two dimensions: coworker match and coworker substitutability. Complementary coworkers raise wages with a comparable factor as does a college degree, whereas working with close substitutes is associated with wage penalties. Moreover, this coworker fit does not only account for large portions of the urban and large-plant wage premiums, but the returns to own schooling and the urban wage premium are almost completely contingent on finding complementary coworkers.

Guven, D. & Miagkyi, M., 2016. Albania's Credit Market.Abstract

Credit market activity in Albania has been sluggish in recent years in spite of low and declining interest rates. The economy lost its growth momentum after 2009. Investment and lending activity slowed down substantially despite low interest rates, relative macroeconomic resilience, and available capacity in the private sector to take on more debt. This study analyzes the supply (lenders’) and demand (borrowers’) sides of the market.

The reason behind the credit market failure is a supply-demand mismatch. Poor financial intermediation is the main problem on the supply side. Despite excess liquidity in the financial sector, banks are excessively risk-averse, bank practices and products are unsophisticated, and non-bank financial market is underdeveloped. Excessive risk aversion translates into tight credit standards, credit rationing and credit crunch for some economic sectors, in particular those dominated by SMEs. On the demand side, firms overall have a low appetite to expand, limited capacity to create bankable and financially viable projects, and are also constrained by infrastructural gaps and economic uncertainty. The mismatch results from the fragmentation of the credit market, with reliable borrowers from traditional sectors having easy access to finance, and other segments being almost fully deprived of credit.

Government and donor-led policies to mitigate the problem have had little success. Albania enjoys access to a number of domestic and external funding schemes primarily focused on alleviating funding constraints for credit-deprived sectors, but these programs have been ineffective. Further study is needed to understand the reasons behind the limited success of these programs.

A National Development Bank (NDB) could address some of the observed credit market challenges. While an NDB’s ability to directly resolve demand-side constraints would be limited, an NDB could effectively tackle supply-side constraints in the credit market as well as provide surveillance and collect information from the private sector, leverage technical assistance, and develop tailored financial products. Establishing an NDB should be considered carefully, taking into account functional, governance, funding, staffing and other risk factors.

Hausmann, R., 2016. Constraints to Sustained and Inclusive Growth in Sri Lanka.Abstract
In late 2015, CID was requested to conduct an initial analysis of constraints to sustained and inclusive economic growth in Sri Lanka. The findings of this analysis were presented at the Sri Lanka Economic Forum in Colombo in January 2016. This presentation outlined the initial findings and offered a series of questions that were then discussed at length with policymakers and academics during the two-day forum. The initial analysis found that recent growth and the sustainability of growth moving forward are constrained by weakness in Sri Lanka’s balance of payments, where a trade imbalance combined with low levels of foreign direct investment effectively puts a speed limit on economic growth. While monetary and exchange rate policy could be used to soften this constraint, solving the underlying problem requires structural transformation, which has proven difficult in Sri Lanka. At the same time, the analysis identified the government’s inability to raise revenues as a major risk that threatens to be more binding moving forward. Finally, the analysis identified the primary dimensions of inequality in the country as between regions and between cities and rural areas.

2016. Sri Lanka’s Edible Oils Exports.Abstract
By request of the Government of Sri Lanka, CID reviewed edible oils exports in September 2016 based on the latest available international trade data. The analysis identified the products and markets key to Sri Lanka’s edible oils sector and compared with competitor countries. Although edible oils are non-complex products that make up a small share of the country’s total exports (0.5% in 2014), they help to diversify Sri Lankan exports and may serve as stepping stones toward further diversification into other more complex exports in the future. Coconut oil, which made up 86% of Sri Lanka’s edible oils exports in 2014, is particularly promising, with exports growing by more than a factor of 10 in just five years and much room to grow based on global demand.
