Public Debt Dynamics and Intra-Year Exchange Rate Fluctuations
Description: The public sector, in carrying out its operations, often incurs foreign currency denominated liabilities and, as such, is exposed to exchange rate fluctuations that could affect the value of public debt to GDP ratios over time. This paper shows that converting foreign currency denominated flows and stocks into local currency using the average and the end-of-period exchange rates, respectively, as envisaged in public finance manuals, gives rise to an identifiable stock-flow adjustment term—due to intra-year exchange rate fluctuations—that affects public debt accumulation. Importantly, the inclusion of this often-ignored stock-flow adjustment term is critical to accurately project public debt levels and any related indicator that could in turn inform about the risk of debt distress. Using a novel dataset covering 82 countries during 2008–19, the paper shows that this stock flow adjustment term is sizable in countries experiencing large exchange rate depreciations, namely above the 99th percentile of the full sample, reaching 1.2 percent of GDP. Interestingly, the measurement of policy-related concepts such as interest rate-growth differentials and debt stabilizing primary balances are also affected by intra-year exchange rate fluctuations, and in non-negligible ways.

Corporate Vulnerabilities in Vietnam and Implications of COVID-19
Description: The paper uses firm-level data to assess the financial health of the Vietnamese non-financial corporate sector on the eve of pandemic. Our analysis finds that smaller domestic firms were particularly vulnerable even by regional comparison. A sensitivity analysis suggests that the COVID-19 shock will have a substantial impact on firms’ profitability, liquidity and even solvency, particularly in the hardest hit sectors that are dominated by SMEs and account for a sizeable employment share, but large firms are not immune to the crisis. Risks of default can propagate more broadly through upstream and downstream linkages to industries not directly impacted, with stresses potentially translating into an increase in corporate bankruptcies and bank fragility. Policy measures taken in the immediate aftermath of the crisis have helped alleviate liquidity pressures, but the nature of policy support may have to pivot to support the recovery.

What Do We Talk About When We Talk About Output Gaps?
Description: Estimates of output gaps continue to play a key role in assessments of the stance of business cycles. This paper uses three approaches to examine the historical record of output gap measurements and their use in surveillance within the IMF. Firstly, the historical record of global output gap estimates shows a firm negative skew, in line with previous regional studies, as well as frequent historical revisions to output gap estimates. Secondly, when looking at the co-movement of output gap estimates and realized measures of slack, a positive, but limited, association is found between the two. Thirdly, text analysis techniques are deployed to assess how estimates of output gaps are used in Fund surveillance. The results reveal no strong bearing of output gap estimates on the coverage of the concept or direction of policy advice. The results suggest the need for continued caution in relying on output gaps for real-time policymaking and policy assessment.

Local Currency Bond Markets Law Reform: A Methodology for Emerging Markets and Developing Economies
Description: Recent financial crises including the ongoing one caused by the COVID-19 pandemic have consistently drawn attention to the need to strengthen the quality of public debt management in emerging markets and developing countries. Deeper and more efficient domestic government debt markets—being, a key segment of the LCBM for many emerging markets and developing economies—play a key role in reducing financial vulnerability to shocks and enable governments to finance critical economic and fiscal policy measures in response to them. Policymakers and international organizations have long recognized that developing and strengthening LCBMs is a key policy prescription to sound public debt management. Robust legal and regulatory frameworks are recognized as being critical building blocks for the structure, development and functioning of LCBMs. This Working Paper seeks to outline a strategically anchored methodology that can be applied to design, build and implement the legal and tax foundations for the development of LCBMs that would adequately address common challenges and impediments.

Technological and Economic Decoupling in the Cyber Era
Description: The COVID-19 pandemic has accelerated the shift toward digital services. Meanwhile, the race for technological and economic leadership has heated up, with risks of decoupling that could set back trade and growth and hinder the recovery from the worst global recession since the Great Depression. This paper studies the conditions under which a country may seek to erect barriers—banning imports or exports of cyber technologies—and in effect promote decoupling or deglobalization. A well-known result is that banning imports may be optimal in monopolistic sectors, such as the digital sector. The novel result of this paper is that banning exports can also be optimal, and in some cases superior, as it prevents technological diffusion to a challenger that may eventually become the global supplier, capturing monopoly rents and posing cybersecurity risks. However, export or import bans would come at a deleterious cost to the global economy. The paper concludes that fostering international cooperation, including in the cyber domain, could be key to avoiding technological and economic decoupling and securing better livelihoods.

Labor Market Informality and the Business Cycle
Description: Labor market informality is a pervasive feature of most developing economies. Motivated by the empirical regularity that the labor informality rate falls with GDP per capita, both at business cycle frequency and in a cross-section of countries, and that the Okun's coefficient falls with the level of labor informality, we build a small open-economy dynamic stochastic general equilibrium model with two sectors, formal and informal, which can replicate these key stylized facts. The model is calibrated to Colombia. The results show that labor market and tax reforms play an important role in changing the informality rate but also caution against over-optimism - with low GDP per capita, informality will always be relatively high as there is insufficient demand for formal goods. Quantitatively we find that higher productivity in the formal sector is key in explaining the difference between Colombia and countries with significantly lower informality. We use the model to study how labor informality and labor market frictions mediate the cyclical response of the economy to shocks, including commodity price shocks which are particularly relevant in Latin America. Informality is shown to play an important role as a shock absorber with the informal-formal margin limiting movements in the employed-unemployed margin.

Banking Across Borders: Are Chinese Banks Different?
Description: We explore the global footprint of Chinese banks and compare it with that of other bank nationalities. Chinese banks have become the largest cross-border creditors for almost half of all emerging market and developing economies (EMDEs). Their global reach resembles that of banks from advanced economies (AEs). We take a nationality approach as international banks, and Chinese banks in particular, grant a substantial share of their cross-border loans from affiliates located abroad. But differences remain. Using a gravity model with a novel measure of distance capturing the role of foreign affiliates across all bank nationalities, we find that larger distances deter cross-border bank lending to EMDEs more than to AEs. For Chinese banks, however, distance deters lending to EMDEs less than for peer EMDE banks. We show that for all banks combined, bilateral economic interactions like trade, FDI and portfolio investment, positively correlate with lending. Chinese banks’ lending to EMDEs also strongly correlates with trade, but not with FDI and, unlike other banks, it correlates negatively with portfolio investment.

China’s Rebalancing: Opportunities and Challenges for LAC Exporters
Description: Asia and Latin America and the Caribbean (LAC), two regions with large growth potential, have become increasingly connected over the last 20 years. China has emerged not only as a top trading partner, but also as an important competitor of LAC exports. China’s retreat from certain markets, due to the ongoing rebalancing process, could open new opportunities for LAC exporters but also entail some challenges. Our results show that China’s rebalancing will have an overall positive effect on LAC’s GDP and exports in the long run, but this effect is small and uneven across countries, leading to winners and losers. We also provide evidence that other countries, such as India, are currently trying to fill the gap left by China and could undermine LAC’s competitive advantage in some export markets. In this context, reduction of trade barriers and further integration within the region and/or with the rest of the world would lead to unequivocally positive outcomes for all LAC countries. The COVID-19 shock might exacerbate the effects identified in our analysis.

Stress Testing U.S. Leveraged Corporates in a COVID-19 World
Description: This paper analyzes a group of 755 firms, with aggregate indebtedness of US$6.2 trillion, to assess the solvency risks and liquidity needs facing the U.S. corporate sector based on projections of net income, availability and cost of funding, and debt servicing flows under different stress test scenarios. The paper finds that leveraged corporates account for most of the potential losses arising from the macroeconomic stresses associated with the COVID-19 crisis, with a concentration of these losses in the oil and gas, auto, and capital and durable goods manufacturing sectors. However, potential losses from corporate debt write-downs appear to be a fraction of banks’ capital buffers and, given the size of the leveraged segment and the relatively long duration of that sector’s debt, the near-term liquidity needs of these corporates appear modest. Corporate stresses could, however, amplify the current economic downturn—as firms cut investment spending and reduce employment—potentially giving rise to significant indirect losses for the financial system.

Pre- and Post-GFC Policy Multipliers
Description: This paper estimates the change in policy multipliers in the U.S. relative to their pre-2008 financial crisis levels using an augmented Blanchard-Perotti model to allow for the dynamic effects of shocks to the central bank balance sheet, real interest rates and debt levels on economic activity. Given the elevated debt level and significantly larger central bank balance sheet in the U.S. after 2008, the paper estimates the likely impact of new stimulus packages. We find that expenditure multipliers have fallen post-2008 crisis because of higher government debt, implying that the effectiveness of fiscal policy has declined. The analysis also investigates the impact of quantitative easing. The results suggest that it is beneficial, but requires sizable balance sheet interventions to lead to noticeable effects on real GDP. The results are used to assess the impact of the policy packages to address COVID-19. Because of rising debt stocks, dealing with a crisis is becoming more and more costly despite the current low interest rate environment.
