Some Alternative Monetary Facts
Description: In this paper, we discuss the modern history of monetarism and its alternatives, as well as the changing empirical relationship of various measures of money and inflation. After demonstrating that previous naïve correlations between money and inflation as established in the 20th century literature have largely disappeared, we explain why this cannot be taken as support for an increased reliance on permanent monetary finance. Rather, we argue that rapid technological innovation in payments systems—both public and private—including in global pledged collateral markets, portends a declining demand for central bank liabilities.

Investor Information and Bank Instability During the Euro Crisis
Description: Outside of financial crises, investors have little incentive to produce private information on banks’ short-term liabilities held as information-insensitive safe assets. The same does not hold true during crises. We measure daily information production using data from credit default swap spreads during the global financial crisis and the subsequent European debt crisis. We study abnormal information production around major events and interventions during these crises and find that, on average, capital injections reduced abnormal information production while early European stress tests increased it. We also link information production to outcomes: high levels of information production predict bank balance sheet contraction and higher government expenditures to support financial institutions. In an addendum, we show information production on nonfinancials dramatically increased relative to financials at the height of the COVID-19 crisis, reflecting the nonfinancial nature of the initial shock.

Politically Robust Financial Regulation
Description: The deferred recognition of COVID-induced losses at banks in many countries has reignited the debate on regulatory forbearance. This paper presents a model where the public's own political pressure drives regulatory policy astray, because the public is poorly informed. Using probabilistic game stages, the model parameterizes how time consistent policy is. The interaction between political motivations and time consistency is novel and complex: increased policy credibility can entice the politically-motivated regulator to act in the public's best interest, or instead repel it from doing so. Considering several regulatory instruments, the paper probes the nexus of political pressure, perverse bank incentives and time inconsistent policy.

Quarterly Projection Model for the National Bank of Rwanda
Description: National Bank of Rwanda (BNR) modernized monetary policy and transited to the price-based policy framework in January 2019. The Forecasting and Policy Analysis System (FPAS) is the cornerstone for the new forward-looking framework, which mobilizes and organizes resources and sets processes for regular forecasting rounds. The core of this system is a structural macroeconomic model for macroeconomic analysis and projections to support the BNR staff’s policy recommendations to the monetary policy committee. This paper documents the quarterly projection model (QPM) at the core of the FPAS at the BNR. The model is an extension of the canonical structure in Berg et al (2006) to reflect specifics of the interest-rate-based policy framework with a managed exchange rate, the effect of agricultural sector and harvests on prices, and the role of fiscal policies and aid flows.

Small and Vulnerable: Small Firm Productivity in the Great Productivity Slowdown
Description: We provide broad-based evidence of a firm size premium of total factor productivity (TFP) growth in Europe after the Global Financial Crisis. The TFP growth of smaller firms was more adversely affected and diverged from their larger counterparts after the crisis. The impact was progressively larger for medium, small, and micro firms relative to large firms. It was also disproportionally larger for firms with limited credit market access. Moreover, smaller firms were less likely to have access to safer banks: those that were better capitalized banks and with a presence in the credit default swap market. Horseraces suggest that firm size may be a more important and robust vulnerability indicator than balance sheet characteristics. Our results imply that the tightening of credit market conditions during the crisis, coupled with limited credit market access especially among micro, small, and medium firms, may have contributed to the large and persistent drop in aggregate TFP.

Predicting Macroeconomic and Macrofinancial Stress in Low-Income Countries
Description: In recent years, Fund staff has prepared cross-country analyses of macroeconomic vulnerabilities in low-income countries, focusing on the risk of sharp declines in economic growth and of debt distress. We discuss routes to broadening this focus by adding several macroeconomic and macrofinancial vulnerability concepts. The associated early warning systems draw on advances in predictive modeling.

Leverage Shocks: Firm-Level Evidence on Debt Overhang and Investment
Description: The global economy is in the midst of an unprecedented slump caused by the coronavirus pandemic. This systemic risk like no other at a time of record-breaking debt levels, especially among nonfinancial firms across the world, could exacerbate corporate vulnerabilities, deepen macro-financial instability, and cause long-lasting damage to economic potential. Using data on more than 2.8 million nonfinancial firms from 52 countries during the period 1997–2018, we develop a two-pronged approach to investigate the relationship between corporate leverage and fixed investment spending. The empirical analysis, robust to a battery of sensitivity checks, confirm corporate leverage is highly vulnerable to disruptions in profitability and cash flow at the firm level and economic growth at the aggregate level. These findings imply that corporate debt overhang could become a strenuous burden on nonfinancial firms, especially if the COVID-19 pandemic lingers and global downturn becomes protracted.

Feeling the Heat: Climate Shocks and Credit Ratings
Description: Climate change is an existential threat to the world economy like no other, with complex, evolving and nonlinear dynamics that remain a source of great uncertainty. There is a bourgeoning literature on the economic impact of climate change, but research on how climate change affects sovereign risks is limited. Building on our previous research focusing on the impact of climate change on sovereign risks, this paper empirically investigates how climate change may affect sovereign credit ratings. By means of binary-choice models, we find that climate change vulnerability has adverse effects on sovereign credit ratings, after controlling for conventional macroeconomic determinants of credit worthiness. On the other hand, with regards to climate change resilience, we find that countries with greater climate change resilience benefit from higher (better) credit ratings. These findings, robust to a battery of sensitivity checks, also show that impact of climate change is disproportionately greater in developing countries due largely to weaker capacity to adapt to and mitigate the consequences of climate change.

Hang in There: Stock Market Reactions to Withdrawals of COVID-19 Stimulus Measures
Description: The COVID-19 pandemic prompted unprecedented economic stimulus worldwide. We empirically examine the impact of a withdrawal of fiscal stimulus policies on the stock markets. After constructing a database of withdrawal events, we use event study analysis and cross-country regressions to assess the difference between the pre- and post-event stock price returns. We find that markets react negatively to premature withdrawals—defined as withdrawals at a time when the daily COVID cases are high relative to their historical average—likely reflecting concerns about the withdrawal impact on the prospects for economic recovery. The design of a successful exit strategy from COVID-19 policy responses should account for these concerns.

Supply Spillovers During the Pandemic: Evidence from High-Frequency Shipping Data
Description: World trade contracted dramatically during the global economic crisis induced by the COVID-19 pandemic. Disruptions in international supply chains were widely reported as governments imposed containment measures (lockdowns) to halt the spread of the disease. At the same time, demand declined as households and firms scaled back spending. This paper attempts to disentangle the supply and demand channels in trade by quantifying the causal effect of supply spillovers from lockdowns. We utilize a novel dataset of daily bilateral seaborne trade, and design a shift-share identification strategy that leverages geography-induced cargo delivery lags to track the transmission of supply disruptions across space. We find strong but short-lived supply spillovers of lockdowns through international trade. Moreover, the evidence is suggestive of the downstream propagation of countries’ lockdowns through global supply chains.
