Sorting It Out: International Trade and Protection With Heterogeneous Workers

The two models of international trade with developed factor markets -- Heckscher-Ohlin and Specific Factors -- both suffer significant defects. For example, their predictions about the patterns of domestic production and international trade are for the most part either indeterminate or uselessly complex. The problem with these models is that the supply of factors to an industry is either perfectly elastic or perfectly inelastic. Using a model in which heterogeneous workers sort across industries we eliminate this problem. The result is a multi-good model with sharp predictions about (1) the domestic pattern of production, (2) North-North and North-South trade, (3) the demand for protection, (4) the determinants of domestic income distribution, and (5) the effect of trade on economic development.

Euroisation in Serbia

Euroisation in Serbia is rooted in a long history of macroeconomic instability. Extreme inflation volatility has undermined trust in the dinar and discouraged dinar savings. At the same time, an abundant supply of foreign capital inflows has provided easy access to foreign currency lending at low interest rates in an environment of perceived exchange rate stability – a perception reinforced by the choice of exchange rate regime. As a result, both the asset and the liability side of banks’ balance sheets, and even those of the non-bank sector, is heavily foreign currency-denominated. This paper documents the forces that promote euroisation in Serbia. The paper argues that, in the wake of the global crisis, a window of opportunity has emerged that could foster a process of de-euroisation. The lack of foreign funding and recent exchange rate volatility has tilted borrower incentives towards local currency borrowing. If disinflationary macroeconomic policies gain credibility, with the possible support of regulatory options, euroisation could drop sharply.

Slowing Growth: More than a rough Patch

Across the world, a structural growth slowdown is underway: at current trends, the global potential growth rate—the maximum rate at which an economy can grow without igniting inflation—is expected to fall to a three-decade low over the remainder of the 2020s. The slowdown could be even more pronounced if financial crises erupt in major economies and spread to other countries, as these types of episodes often lead to lasting damage to potential growth. A persistent and broad-based decline in long-term growth prospects imperils the ability of emerging market and developing economies (EMDEs) to combat poverty, tackle climate change, and meet other key development objectives. These challenges call for an ambitious policy response at the national and global levels

Election-induced fiscal policy cycles in emerging market and developing economies

The widening of fiscal deficits during democratic elections is well established. We examine a broader set of fiscal outcomes around elections for a large set of emerging and developing economies (EMDEs), probe for differences between democracies and non-democracies, and estimate the degree to which fiscal deteriorations are unwound after elections. We show three patterns. First, primary deficits rise statistically significantly during elections, by 0.6 percentage points of GDP. Primary spending, especially on the government wage bill, also rises statistically significantly, and indirect tax revenues fall. Second, these deteriorations occur in democracies and non-democracies alike. Third, the deterioration in primary deficits is not unwound after elections and the deterioration in primary spending is partially unwound after the election, mainly through cuts in capital spending. These patterns imply that deficits in EMDEs ratchet up over the course of several election cycles. Over time, this can threaten the sustainability of public finances. Finally, we find that better institutional quality (such as strong fiscal rules) and the presence of an IMF program partly mitigate the impact of elections on fiscal positions

From Low to High Inflation: Implications for Emerging Market and Developing Economies

Recent energy and food price surges, in the wake of Russia’s invasion of Ukraine, have exacerbated inflation pressures that are unusually high by the standards of the past two decades. High and rising inflation has prompted many emerging market and developing economy (EMDE) central banks and some advanced-economy central banks to increase interest rates. Inflation is expected to ease back towards targets over the medium-term as recent shocks unwind, but the 1970s experience is a reminder of the material risks to this outlook. As inflation remains elevated, the risk is growing that, to bring inflation back to target, advanced economies need to undertake a much more forceful monetary policy response than currently anticipated. If this risk materializes, it would imply additional increases in borrowing costs for EMDEs, which are already struggling to cope with elevated inflation at home before the recovery from the pandemic is complete. EMDEs need to focus on calibrating their policies with macroeconomic stability in mind, communicating their plans clearly, and preserving and building their credibility

Potential Growth Prospects: Risks, Rewards, and Policies

Potential output growth around the world slowed over the past two decades. This slowdown is expected to continue in the remainder of the 2020s: global potential growth is projected to average 2.2 percent per year in 2022-30, 0.4 percentage point below its 2011-21 average. Emerging market and developing economies (EMDEs) will face an even steeper slowdown, of about 1.0 percentage point to 4.0 percent per year on average during 2022-30. The slowdown will be widespread, affecting most EMDEs and countries accounting for 70 percent of global GDP. Global potential growth over the remainder of this decade could be even slower than projected in the baseline scenario—by another 0.2-0.9 percentage point a year—if investment growth, improvements in health and education outcomes, or developments in labor markets disappoint, or if adverse events materialize. A menu of policy options is available to help reverse the trend of weakening economic growth, including policies to enhance physical and human capital accumulation; to encourage labor force participation by women and older adults; to improve the efficiency of public spending; and to mitigate and adapt to climate change, including infrastructure investment to facilitate the green transition

Understanding Informality

This paper introduces a comprehensive database of informal economic activity. The database focuses on measures that have strong cross-country and over time coverage: it includes both model-based and survey-based measures of informality and covers more than 160 economies for the period 1990-2018. The paper illustrates two applications of the database. First, it distills stylized facts of informal activity, including its declining trend and pervasiveness in emerging market and developing economies (EMDEs). Second, it documents the cyclical features of the informal economy. Overall, informal economy recessions (recoveries) do not differ significantly from those of formal economy. Like formal-economy business cycles, informal-economy business cycles tend to be shallower in advanced economies than in EMDEs. Informal employment in both advanced economies and EMDEs appears to be largely acyclical

What Explains Global Inflation

This paper examines the drivers of fluctuations in global inflation, defined as a common factor across monthly headline consumer price index (CPI) inflation in G7 countries, over the past half-century. We estimate a Factor-Augmented Vector Autoregression model where a wide range of shocks, including global demand, supply, oil price, and interest rate shocks, are identified through narrative sign restrictions motivated by the predictions of a simple dynamic general equilibrium model. We report three main results. First, oil price shocks followed by global demand shocks explained the lion’s share of variation in global inflation. Second, the contribution of global demand and oil price shocks increased over time, from 56 percent during 1970-1985 to 65 percent during 2001-2022, whereas the importance of global supply shocks declined. Since the pandemic, global demand and oil price shocks have accounted for most of the variation in global inflation. Finally, oil price shocks played a much smaller role in global core CPI inflation variation, for which global supply shocks were the main source of variation. These results are robust to various sensitivity exercises, including alternative definitions of global variables, different samples of countries, and additional narrative restrictions

Growing Apart or Moving Together? Synchronization of Informal and Formal Economy Cycles

We study the degree of synchronization between formal- and informal-economy business cycles. Using a comprehensive database of informal activity that covers a wide range of informality measures from almost 160 countries over the 1990-2018 period, we report two major results. First, fluctuations in informal-sector output are strongly positively correlated with those in formal-sector output. In contrast, fluctuations in informal employment are largely uncorrelated with those in formal-sector output. Second, movements in the formal economy tend to spillover to the informal economy. Using a novel set of instrumental variables, we show that fluctuations in formal-sector output “cause” movements in informal-sector output

Potential Growth: A Global Database

Potential growth—the rate of expansion an economy can sustain at full capacity and employment—is a critical driver of development progress. It is also a major input in the formulation of fiscal and monetary policies over the business cycle. This paper introduces the most comprehensive database to date, covering the nine most commonly used measures of potential growth for up to 173 countries over 1981-2021. Based on this database, the paper presents three findings. First, all measures of global potential growth show a steady and widespread decline over the past decade, with all the fundamental drivers of growth losing momentum over time. In 2011-21, potential growth was below its 2000-10 average in nearly all advanced economies and roughly 60 percent of emerging market and developing economies. Second, adverse events, such as the global financial crisis and the COVID-19 pandemic, contributed to the decline. At the country-level also, national recessions lowered potential growth even five years after their onset. Third, the persistent impact of recessions on potential growth operated through weaker growth of investment, employment, and productivity
