Taxing Telecommunications in Developing Countries
Description: Developing countries apply numerous sector-specific taxes to telecommunications, whose buoyant revenues and formal enterprises provide a convenient “tax handle”. This paper explores whether there is an economic rationale for sector-specific taxes on telecommunications and, if so, what form they should take to balance the competing goals of promoting connectivity and mobilizing revenues. A survey of the literature finds that limited telecoms competition likely creates rents that could efficiently be taxed. We propose a “pecking order” of sector-specific taxes that could be levied in addition to standard income and value-added taxes, based on capturing rents and minimizing distortions. Taxes that target possible economic rents or profits are preferable, but their administrative challenges may necessitate reliance on service excises at the cost of higher consumer prices and lower connectivity. Taxes on capital inputs and consumer access, which distort production and restrict network access, should be avoided; so should tax incentives, which are not needed to attract foreign capital to tap a local market.

Global Trade and the Dollar
Description: We document that the U.S. dollar exchange rate drives global trade prices and volumes. Using a newly constructed data set of bilateral price and volume indices for more than 2,500 country pairs, we establish the following facts: 1) The dollar exchange rate quantitatively dominates the bilateral exchange rate in price pass-through and trade elasticity regressions. U.S. monetary policy induced dollar fluctuations have high pass-through into bilateral import prices. 2) Bilateral non-commodities terms of trade are essentially uncorrelated with bilateral exchange rates. 3) The strength of the U.S. dollar is a key predictor of rest-of-world aggregate trade volume and consumer/producer price inflation. A 1 percent U.S. dollar appreciation against all other currencies in the world predicts a 0.6–0.8 percent decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle. 4) Using a novel Bayesian semiparametric hierarchical panel data model, we estimate that the importing country’s share of imports invoiced in dollars explains 15 percent of the variance of dollar pass-through/elasticity across country pairs. Our findings strongly support the dominant currency paradigm as opposed to the traditional Mundell-Fleming pricing paradigms.

Potential Growth in Colombia
Description: This paper uses a multivariate filter and a production function to project potential growth in Colombia, modeling in detail the impact of low oil prices on investment. The framework also captures the impact of current and planned policies on potential growth, including the peace agreement with the FARC, the tax reform, and 4G infrastructure projects. The analysis suggests the growth acceleration of the 2000s is unlikely to repeat itself in a world of lower oil prices. Potential growth is likely to moderate to a range of 2.8 to 4.1 percent. The 4G infrastructure projects and the tax reform will increase investment, partly offsetting the sharp decline in oil investment. Improvements in productivity are essential to lift potential growth, as the large increases in the labor force observed in the last 15 years are unlikely to continue.

Unconventional Policies and Exchange Rate Dynamics
Description: We study exchange rate dynamics under cooperative and self-oriented policies in a two-country DSGE model with unconventional monetary and exchange rate policies. The cooperative solution features a large exchange rate adjustment that cushions the impact of negative shocks and a moderate use of unconventional policy instruments. Self-oriented policies (Nash equilibrium), however, entail limited exchange rate movements and an aggressive use of unconventional policies in both countries. Our results highlight the role of international policy cooperation in allowing the exchange rate to play the traditional role of shock absorber.

Inequality in Financial Inclusion and Income Inequality
Description: We investigate the link between gender inequality in financial inclusion and income inequality, with three contributions to the recent literature. First, using a micro-dataset covering 146,000 individuals in over 140 countries, we construct novel, synthetic indices of the intensity of financial inclusion at the individual and country level. Second, we derive the distribution of individual financial access “scores” across countries to document a “Kuznets”-curve in financial inclusion. Third, cross-country regressions confirm that our measure of inequality in financial access is significantly related to income inequality, above and beyond other factors previously highlighted in the literature.

The Macro-Fiscal Aftermath of Weather-Related Disasters: Do Loss Dimensions Matter?
Description: Weather-related natural disasters and climate change pose interrelated macro-fiscal challenges. Using panel-VARX studies for a sample of 19 countries in Developing Asia during 1970 to 2015, this paper contributes new empirical evidence on the dynamic adjustment path of growth and key fiscal variables after severe weather-related disasters. It does not only show that output loss can be permanent, but even twice as large for cases of severe casualties or material damages than people affected. Meanwhile, key fiscal aggregates remain surprisingly stable. Event and case studies suggest that this can reflect both a deliberate policy choice or binding constraints. The latter can make governments respond through mitigating fiscal policy efforts such as ad hoc fiscal rebalancing and reprioritization. The findings help better customize disaster preparedness and mitigation efforts to countries’ risk exposure along a particular loss dimension.

Trade and Income in the Long Run: Are There Really Gains, and Are They Widely Shared?
Description: In the cross section of countries, there is a strong positive correlation between trade and income, and a negative relationship between trade and inequality. Does this reflect a causal relationship? We adopt the Frankel and Romer (1999) identification strategy, and exploit countries' exogenous geographic characteristics to estimate the causal effect of trade on income and inequality. Our cross-country estimates for trade's impact on real income are consistently positive and significant over time. At the same time, we do not find any statistical evidence that more trade increases aggregate measures of income inequality. Heeding previous concerns in the literature (e.g. Rodriguez and Rodrik, 2001; Rodrik, Subramanian and Trebbi, 2004), we carefully analyze the validity of our geography-based instrument, and confirm that the IV estimates for the impact of trade are not driven by other direct or indirect effects of geography through non-trade channels.

Problem Loans in the Caribbean: Determinants, Impact and Strategies for Resolution
Description: The high level of nonperforming loans (NPLs) in the Caribbean has been, in large part, a legacy of the global financial crisis, but their persistence owes much to the weak economic recovery in the region, as well as to structural obstacles to their resolution. A comprehensive strategy is needed to address these impediments to sever the adverse feedback loops between weak economic activity and weak asset quality. This paper finds that NPLs are a drag on Caribbean growth and macro-financial links are strong: a deterioration in asset quality hinders bank lending and dampens economic activity, undermining, in turn, efforts to resolve problem loans. A multifaceted approach is needed, involving a combination of macro- economic policies to support growth and employment; strong supervisory frameworks to ensure macro-financial stability and create incentives for resolution; efforts to address informational gaps and deficiencies in insolvency and debt-enforcement frameworks; and development of markets for distressed loans. The institutional capacity constraints require coordination of reforms within the region and support from international organizations through capacity-building.

The Granular Origins of Macroeconomic Fluctuations in Europe
Description: This paper investigates the microeconomic origins of aggregate economic fluctuations in Europe. It examines the relevance of idiosyncratic shocks at the top 100 large firms (the granular shocks) in explaining aggregate macroeconomic fluctuations. The paper also assesses the strength of spillovers from large firms onto SMEs. Using firm-level data covering over 14 million firms and eight european countries (Austria, Belgium, Finland, France, Germany, Italy, Portugal and Spain), we find that: (i) 40 percent of the variance in GDP in the sample can be explained by idiosyncratic shocks at large firms; (ii) positive granular shocks at large firms spill over to domestic SMEs’ output, especially if SMEs’ balance sheets are healthy and if SMEs belong to the services and manufacturing sectors.

A Generalized Framework for the Assessment of Household Financial Vulnerability
Description: Household financial fragility has received considerable attention following the global financial crisis, but substantial gaps remain in the analytical underpinnings of household financial vulnerability assessment, as well as in data availability. This paper aims at integrating the contributions in the literature in a coherent fashion. The study proposes also analytical and estimation extensions aimed at improving the quality of estimates and allowing the assessment of household financial vulnerability in presence of data limitations. The result of this effort is a comprehensive framework, that has wide applicability to both advanced and developing economies. For illustrative purposes the paper includes a detailed application to one developing country (Namibia).
