Fiscal adjustment in Latin America and the Caribbean : short-run pain, long-run gain?

After a growth slowdown that lasted six years, the Latin America and the Caribbean (LAC) region has finally turned the corner and resumed growth at a modest rate of 1.1 percent in 2017 and 1.8 percent expected in 2018. This reflects a more favorable external environment, particularly a recovery in commodity prices. In spite of the benign external environment, most LAC countries still face a fragile fiscal situation. While gradual fiscal adjustments have started in several countries, most countries are still running fiscal deficits and debt levels are high. Further fiscal consolidation is needed to preserve the substantial gains achieved by the region in recent times, in terms of lower inflation, less poverty and inequality, and inclusive growth. This Semiannual Report analyzes the complex decisions regarding fiscal adjustment policies

From Known Unknowns to Black Swans

After a growth recovery, with an expansion of 1.1 percent in 2017, the region has encountered some bumps in the road. The Latin America and the Caribbean (LAC) region is expected to grow at a modest rate of 0.6 percent in 2018 and 1.6 percent in 2019. This slowdown in the region’s recovery is mainly explained by the crisis that started in Argentina in April, the growth slowdown in Brazil, and the continuing economic, social, and humanitarian collapse in Venezuela. Furthermore, net capital inflows to the region have fallen dramatically since early 2018, bringing once again to the fore the risks faced by LAC. In addition, natural disasters such as earthquakes and hurricanes have brought devastation to the region with disturbing frequency. The core of the report analyzes the foundations of risk, develops a theoretical framework to price risk instruments, and reviews how LAC has managed risk in practice. The overall message of the report is that there are different types of risk: (i) those that follow standard probabilistic distributions that can be easily insured by the market; and (ii) those that exhibit fat-tails (i.e., non-negligible probabilities of extreme events) that are much harder to ensure by the market (like earthquakes). Finally, there are “black swans” that, by definition, are unpredictable events that cannot be insured and force countries to rely exclusively on ex-post aid and/or broad preventive measures. In other words, the fatter are the tails of a distribution, the less market insurance is available, and the more countries will have to rely on ex-post aid. Yet progress in managing risk continues to be made (the Catastrophe Bond for earthquakes in the Pacific Alliance, recently sponsored by the World Bank, being an outstanding example). This would have been unthinkable some time ago. New knowledge and insurance schemes, all supported by institutions such as the World Bank, will undoubtedly make LAC a safer region to live and prosper.

Non-Linear Distortion-Based Effects of Tax Changes on Output: A Worldwide Narrative Approach

We estimate the effect of worldwide tax changes on output following the narrative approach developed for the United States by Romer and Romer (2010). We use a novel dataset on value-added taxes for 51 countries (21 industrial and 30 developing) for the period 1970-2014 to identify 96 tax changes. We then use contemporaneous economic records to classify such changes as endogenous or exogenous to current (or prospective) economic conditions. In line with existing theoretical distortion-based arguments and based on the exogenous tax changes we and that the effect of tax changes on output is highly non-linear. The tax multiplier is essentially zero under relatively low/moderate initial tax rate levels and much larger (in absolute terms) as the initial tax rate and the size of the change in the tax rate increases.
