Unintended Effects From the Expansion of the Non-Contributory Health System in Peru
Description: Over the last two decades, the Peruvian government has made great efforts to improve access to health care by significantly augmenting the coverage of the non-contributory public health care system Seguro Integral de Salud (SIS). This expansion has a positive impact on welfare and public health indicators, as it limits the risk of catastrophic health-related costs for previously uninsured individuals and allows for the appropriate treatment of illnesses. However, it also entails some unintended consequences for informality, tax revenues, and GDP, since a few formal agents are paying for a service that the majority of (informal) agents receive for free. In this paper, we use a general equilibrium model calibrated for Peru to simulate the expansion of SIS to quantify the unintended effects. We find that overall welfare increases, but informality rises by 2.7 percent, while tax revenues and output decrease by roughly 0.1 percent. Given the extent of the expansion in eligibility, the economic relevance of these results seems negligible. However, this occurs because the expansion of coverage was mostly funded by reducing the spending per-insured person. In fact, we find larger costs if public spending is increased to improve the quality of service given universal coverage.

Competition vs. Stability: Oligopolistic Banking System with Run Risk
Description: This paper develops a model where large financial intermediaries subject to systemic runs internalize the effect of their leverage on aggregate risk, returns and asset prices. Near the steady-state, they restrict leverage to avoid the risk of a run which gives rise to an accelerator effect. For large adverse shocks, the system enters a zone with high leverage and possibly runs. The length of time the system remains in this zone depends on the degree of concentration through a franchise value, price-drop and recapitalization channels. The speed of entry of new banks after a collapse has a stabilizing effect.

Gender and Employment in the COVID-19 Recession: Evidence on “She-cessions”
Description: Early evidence on the pandemic’s effects pointed to women’s employment falling disproportionately, leading observers to call a “she-cession.” This paper documents the extent and persistence of this phenomenon in a quarterly sample of 38 advanced and emerging market economies. We show that there is a large degree of heterogeneity across countries, with over half to two-thirds exhibiting larger declines in women’s than men’s employment rates. These gender differences in COVID-19’s effects are typically short-lived, lasting only a quarter or two on average. We also show that she-cessions are strongly related to COVID-19’s impacts on gender shares in employment within sectors.

Emerging Market Securities Access to Global Plumbing
Description: What are the constraints that have stalled EMs efforts to reuse their securities in international financial centers? We discuss the economics of collateral re-use and the present institutional structure in Asian and Latin American countries. Our empirical investigation suggests pledgeability enhances financial stability and reduces dollar funding risk. We also explain the Eurozone collateral pool to incentivize EMs, and why many securities (e.g., BTPs, Italy) are acceptable in London but not EM securities. Looking forward, EMs liaison with International Central Securities Depositories (ICSDs), and global banks’ balance sheet capacity to intermediate cross-border collateral will be crucial for this market to develop.

What's in the R- Stars for Korea?
Description: Korea’s stars tell of an economy saddled with a real neutral rate (r-star) that has declined significantly in recent decades and is currently below zero. This reflects a significant decline in trend growth, and two large financial crises that triggered significant shifts in the saving-investment balance. Larger fiscal deficits and frothy financial conditions since 2012 have helped offset rising demand for safer assets, preventing the neutral rate from falling further. Nonetheless, the fall in the neutral rate, coupled with its effects on asset returns, has complicated the task of monetary policy stabilization. Korea’s neutral rate is likely to remain low over the medium-term and could fall further, reflecting a structural savings-investment imbalance owing to declining productivity and a rotation in demographics increasing the demand for precautionary saving and convenience yield, and widening the capital risk premia. The COVID pandemic risks magnifying these trends.

Korea’s Growth Prospects: Overcoming Demographics and COVID-19
Description: Korea’s economy has leaped to high-income status thanks to several decades of sustained high growth. However, population aging and shifts in global demand provide headwinds for future growth and Korea now faces the effects of COVID-19 on economic activity. This paper asseses the expected drag on potential growth from these factors and discusses policies that could provide offsetting upward momentum by facilitating structural transformation. We find that potential output growth slowed to about 2½ percent before the COVID-19 pandemic and would have fallen to 2 percent by 2030, mainly due to demographic factors. Moreover, there is a possibility of scarring from the COVID-19 shock as adjustment frictions from structural rigidities interact with shifts in demand and supply patterns, lowering investment and labor force participation. At the same time, industry-level analysis suggests ample scope to raise productivity, especially in services where productivity gains have lagged. Addressing these rigidities could offset a large proportion of the expected downward pressure on potential output.

Building Back Better: How Big Are Green Spending Multipliers?
Description: This paper provides estimates of output multipliers for spending in clean energy and biodiversity conservation, as well as for spending on non-ecofriendly energy and land use activities. Using a new international dataset, we find that every dollar spent on key carbon-neutral or carbon-sink activities can generate more than a dollar’s worth of economic activity. Although not all green and non-ecofriendly expenditures in the dataset are strictly comparable due to data limitations, estimated multipliers associated with spending on renewable and fossil fuel energy investment are comparable, and the former (1.1-1.5) are larger than the latter (0.5-0.6) with over 90 percent probability. These findings survive several robustness checks and lend support to bottom-up analyses arguing that stabilizing climate and reversing biodiversity loss are not at odds with continuing economic advances.

The Political Economy of Inclusive Growth: A Review
Description: In this paper, we review the role of the political economy in inclusive growth. We find that political economy forces on the demand and supply side have weakened redistribution over time and contributed to a new wave of populism. We document growing support for a rethink of the social contract to make growth more inclusive and discuss some of its broad elements.

Pricing Protest: The Response of Financial Markets to Social Unrest
Description: Using a new daily index of social unrest, we provide systematic evidence on the negative impact of social unrest on stock market performance. An average social unrest episode in an typical country causes a 1.4 percentage point drop in cumulative abnormal returns over a two-week event window. This drop is more pronounced for events that last longer and for events that happen in emerging markets. Stronger institutions, particularly better governance and more democratic systems, mitigate the adverse impact of social unrest on stock market returns.

Monetary Policy, Inflation, and Distributional Impact: South Africa’s Case
Description: The South African Reserve Bank has continued to fulfill its constitutional mandate to protect the value of the local currency by keeping inflation low and steady. This paper provides evidence that monetary policy tightening aimed at maintaining low and stable inflation could at the same time reduce consumption inequality over a 12–18 month horizon, commonly understood as the transmission lag of monetary policy action to the real economy, and similar to the distance between survey waves used in the analysis. In response to “exogenous” monetary policy tightening, the real consumption of individuals at lower ends of the consumption distribution declines relatively modestly, or even increases. With greater reliance on government transfers, thus smaller reliance on labor income, and relatively larger food consumption, these individuals appear to benefit mainly from lower inflation. By contrast, the real consumption of individuals at higher ends of the consumption distribution is more likely to decline due to lower labor income, weaker asset price performance, and higher debt service cost.
