Information and Inequality in the Time of a Pandemic
Description: We introduce two types of agent heterogeneity in a calibrated epidemiological search model. First, some agents cannot afford staying home to minimize their virus exposure, while others can. Our results show that these poor agents bear most of the epidemic’s health costs. Moreover, we show that having more agents who do not change their behavior during the pandemic could lead to a deeper recession. Second, agents are heterogeneous in developing symptoms. We show that diseases with higher share of asymptomatic cases, even if less lethal, lead to worse health and economic outcomes. Public policies such as testing, quarantining, and lockdowns are particularly beneficial in economies with a larger share of poor agents. However, lockdowns lose effectiveness when part of the agents take precautions to minimize virus exposure independent of government actions.

Exchange Rates and Domestic Credit—Can Macroprudential Policy Reduce the Link?
Description: This paper examines empirically the role of macroprudential policy in addressing the effects of external shocks on financial stability. In a sample of 62 economies over the period of 2000: Q1–2016: Q4, our dynamic panel regressions show that an appreciation of the local exchange rate is associated with a subsequent increase in the domestic credit gap, while a prior tightening of macroprudential policies dampens this effect. These results are strong for small open economies, and robust when we explicitly account for potential simultaneity and reverse causality biases. We also examine a feedback effect where strong domestic credit pulls in additional cross-border funding, potentially further increasing systemic risk, and find that targeted capital controls can play a complementary role in alleviating this effect.

What Drives Bank Lending Spreads and Collateral Requirements in the Kyrgyz Republic
Description: Limited access to finance and its high cost have contributed to relatively low levels of private investment and subpar growth in the Kyrgyz Republic. Interest rate spreads have moderated in recent years, but remain high from both a regional and global perspective. At the same time, collateral requirements applied by banks are onerous and also constrain the quantity of credit supplied. This paper identifies a range of factors that could lower spreads in the Kyrgyz Republic: more competition, higher capital, lower credit risk, larger loan size, lower deposit rates and external funding costs, as well as a stronger legal framework. Lower operating costs appear critical to reduce relatively higher spreads for small and medium-sized banks. At the same time, a stronger legal framework and greater transparency on borrowers’ creditworthiness would help reduce the high collateral requirements. Reforms in all these areas would support greater financial inclusion in the aftermath of the pandemic, and could thus be a key source of sustainable and inclusive growth in the Kyrgyz Republic.

Impact of Remittances on Natural Rate of Dollarization—Trends in Caucasus and Central Asia
Description: This paper discusses migration and remittances trends, and calculates the natural (or benchmark) level of dollarization in Caucasus, Central Asia and others in the region. This natural level of dollarization is conceptually linked to the currency allocation in a portfolio of deposits to maximize welfare, in line with Ize and Levy Yeyati (2003). The fall in remittances due to the economic slowdown since the spread of COVID-19 affects the macroeconomic fundamentals that determine demand for foreign currency deposits. We calculate the natural dollarization level by integrating structural macroeconomic characteristics. We show that despite the reduction in deposit dollarization, there is still a gap with respect to the natural level of dollarization, especially in a scenario of (persistent) lower remittance inflows.

Will the AI Revolution Cause a Great Divergence?
Description: This paper considers the implications for developing countries of a new wave of technological change that substitutes pervasively for labor. It makes simple and plausible assumptions: the AI revolution can be modeled as an increase in productivity of a distinct type of capital that substitutes closely with labor; and the only fundamental difference between the advanced and developing country is the level of TFP. This set-up is minimalist, but the resulting conclusions are powerful: improvements in the productivity of “robots” drive divergence, as advanced countries differentially benefit from their initially higher robot intensity, driven by their endogenously higher wages and stock of complementary traditional capital. In addition, capital—if internationally mobile—is pulled “uphill”, resulting in a transitional GDP decline in the developing country. In an extended model where robots substitute only for unskilled labor, the terms of trade, and hence GDP, may decline permanently for the country relatively well-endowed in unskilled labor.

Review of the Public Financial Management Reform Strategy for Pacific Island Countries, 2010-2020
Description: This paper reviews the Public Financial Management (PFM) reform stategy for 16 Pacific Island Countries (PICs) during the period 2010-2020. The strategy was endorsed by the finance and economic ministers of the region (FEMM) in 2010. The paper analyzes more than 30 PEFA assessments carried out across the region. The region shares the generally slow pace of PFM reform that is also a feature of most developing countries. Some PICs have improved their PFM performance significantly, while others have done less well. PFM reforms have suffered from the small size and low capacity of many PICs, poorly designed PFM roadmaps, variable political suppport for reform, and vulnerability to natural disasters. The paper recommends that in the next five years, there should be a more granular and targeted approch to PEFAs. PICs should focus on basic PFM reforms and (where capacities allow) more transparent public finances, as well as better management of climate change considerations, public infrastructure, gender inequalities, and state-owned enterprises. Perseverance by countries in implementing reforms and leadership by finance ministries are critical. PFTAC’s advice is highly regarded across the region, and it could consider alternative modalities of CD delivery and stronger coordination with other development partners.

Reducing Risk While Sharing It: A Fiscal Recipe for The EU at the Time of COVID-19
Description: The COVID-19 lockdowns have brought about the need of large fiscal responses in all European countries. However, countries across Europe are differently equipped to respond to the shock due to differences in economic conditions and fiscal space. We build on the model by Berger et al. (2019) to compare gains from alternative mechanisms of EU fiscal integration in the presence of moral hazard. We show that any EU response strategy to the COVID-19 crisis excluding mutual financial support to member countries lacks credibility. Some form of fiscal risk sharing is indeed better than none, especially in presence of increasing sovereign default risk of some EU member countries. The moral hazard created by risk sharing can be hedged by introducing some form of fiscal delegation to Brussels. The desirable level of delegation, however, depends on its costs. When these are low, risk sharing and delegation are substitutes and it is optimal to opt for high delegation and low risk sharing. On the contrary, when delegation costs are high, centralization and risk sharing are complements and both are needed. Proposed arrangements at the EU level in response to the COVID-19 shock seem to reflect these basic insights by rotating around a combination of fiscal risk sharing and delegation in the form of fiscal spending conditionality.

Monetary Policy Under an Exchange Rate Anchor
Description: This paper argues that there is scope for monetary policy under an exchange rate anchor, and discusses the related monetary policy design and implementation. It shows that the exchange rate can be used as the main monetary policy instrument while the policy rate can target the exchange rate. An exchange rate anchor is compatible with an inflation objective, provided fiscal dominance is not an issue, monetary conditions are supportive of the peg, and the level of international reserves is adequate. The paper argues that, while an exchange rate anchor is more prone to policy inconsistencies, there is ample scope for strengthening monetary policy design and implementation under soft pegs. In that context, the principles of dichotomy and interest rate parity are critical.

Offshore Currency Markets: Non-Deliverable Forwards (NDFs) in Asia
Description: Non-deliverable forward (NDF) markets in many Asian emerging market currencies are large, rapidly growing, and often exceed onshore markets in transaction volume. NDFs tend to price significant depreciation during market stress episodes including COVID-19. Spillovers from NDFs to onshore markets are a policymaker concern. Our analysis shows that influences tend to run both ways after controlling for differences in timezones between markets. For the COVID-19 pandemic there is some evidence of NDFs leading onshore markets for a few currencies. Policy approaches to NDFs vary widely across Asia from close integration with onshore markets to severe restrictions on NDF trading.

Global Firms, National Corporate Taxes: An Evolution of Incompatibility
Description: How did the rise of multinational enterprises (MNEs) put pressure on the prevailing international corporate tax framework? MNEs, and firms with market power, are not new phenomena, nor is the corporate income tax, which dates to the early 20th century. This prompts the question, what is distinctly new (about multinational enterprises)—if anything—that has triggered unprecedented recent concerns about vulnerabilities in international tax arrangements and the taxation of MNEs? This paper presents a set of empirical observations and a synthesis of strands of the literature to answer this question. A key message is that MNEs of the 21st century operate differently from prior periods and have evolved to become global firms—with important tax ramifications. The fragility of international tax arrangements was present at the outset of designing international tax rules, but the challenges have drastically intensified with the global integration of business, the increased trade in hard-to-price services and intangibles, and the rapid growth of the digital economy.
