The Crypto Cycle and US Monetary Policy
Description: We examine fluctuations in crypto markets and their relationships to global equity markets and US monetary policy. We identify a single price component—which we label the “crypto factor”—that explains 80% of variation in crypto prices, and show that its increasing correlation with equity markets coincided with the entry of institutional investors into crypto markets. We also document that, as for equities, US Fed tightening reduces the crypto factor through the risk-taking channel—in contrast to claims that crypto assets provide a hedge against market risk. Finally, we show that a stylized heterogeneous-agent model with time-varying aggregate risk aversion can explain our empirical findings, and highlights possible spillovers from crypto to equity markets if the participation of institutional investors ever became large.

Revisiting Covid Scarring in Emerging Markets
Description: The Covid-19 pandemic is expected to result in large and persistent losses in economic output, known as scarring. These losses were expected to be more severe in Emerging Markets than in Advanced Economies. This paper examines the impact of Covid on output in Emerging Markets so far and its implications for projections of economic scarring. While Covid has had a material impact on activity, the recovery has been stronger than initially expected. We find that these positive data surprises have over time been treated increasingly as transitory rather than a signal for the state of scarring. Second, we show that the composition of output losses has been qualitatively different from past last shocks. History suggests that the main driver of scarring is weak productivity. Covid losses, however, have so far been more skewed to employment with a smaller than usual impact on productivity. We argue that these findings suggest that scarring, while substantial, may be ultimately less severe than initially feared, at least over the medium term. We provide alternative sets of medium-term projections to indicate potential magnitudes.

International Tax Spillovers and Tangible Investment, with Implications for the Global Minimum Tax
Description: This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host’s rate; larger than previous consensus values (attributed to a systematic bias from FDI data); and consistent with ‘implicit’ profit shifting through real investment (rather than ‘paper’ profit shifting). Contrary to much policy discussion, the results also imply that: Host countries’ marginal effective tax rates have at best a weak effect on real investment; those elsewhere have none; and, applied to the prospective global minimum tax, inward tangible investment in most sample countries will increase.

Panel Nowcasting for Countries Whose Quarterly GDPs are Unavailable
Description: Quarterly GDP statistics facilitate timely economic assessment, but the availability of such data are limited for more than 60 developing economies, including about 20 countries in sub-Saharan Africa as well as more than two-thirds of fragile and conflict-affected states. To address this limited data availablity, this paper proposes a panel approach that utilizes a statistical relationship estimated from countries where data are available, to estimate quarterly GDP statistics for countries that do not publish such statistics by leveraging the indicators readily available for many countries. This framework demonstrates potential, especially when applied for similar country groups, and could provide valuable real-time insights into economic conditions supported by empirical evidence.

Predicting Financial Crises: The Role of Asset Prices
Description: We explore the early warning properties of a composite indicator which summarizes signals from a range of asset price growth and asset price volatility indicators to capture mispricing of risk in asset markets. Using a quarterly panel of 108 advanced and emerging economies over 1995-2017, we show that the combination of rapid asset price growth and low asset price volatility is a good predictor of future financial crises. Elevated levels of our indicator significantly increase the probability of entering a crisis within the next three years relative to normal times when the indicator is not elevated. The indicator outperforms credit-based early warning metrics, a result robust to prediction horizons, methodological choices, and income groups. Our results are consistent with the idea that measures based on asset prices can offer critical information about systemic risk levels to policymakers.

Do Corporate Bond Shocks Affect Commercial Bank Lending?
Description: Understanding how corporate bond market disruptions are transmitted to the rest of the financial system is essential to gauge systemic financial risk and design policy responses. In this study, we extend the vector autoregression model of Gilchrist and Zakrajšek (2012) to explicitly account for the role of commercial banks in the transmission of corporate bond credit spread shocks. We find that corporate bond market shocks can reduce commercial bank lending activity by tightening loan supply. Policies designed to contain stress in the corporate bond market can thus mitigate systemic risk by limiting contagion to the commercial banking sector.

Macroeconomic Uncertainty and Capital-Skill Complementarity
Description: I examine the impact of macroeconomic uncertainty on labor market outcomes for skilled and unskilled workers and propose a new channel to improve our understanding of the underlying propagation mechanisms. I find that uncertainty shocks are recessionary with the unskilled experiencing a steeper fall in employment. To rationalize these findings, I build a New Keynesian DSGE model with skill heterogeneity and wage rigidities, which, coupled with precautionary labor supply, significantly amplify contractionary effects of uncertainty on the real economy.

Fiscal Policy and the Government Balance Sheet in China
Description: In this paper, we present the most comprehensive estimates of China’s government balance sheet to date. Based on these estimates, we show how major shifts in fiscal policy over the last two decades have shaped the health of the public sector prior to the Covid-19 pandemic. We find that, at US$12.5 trillion, China has the largest stock of financial assets in the world. However, its net financial worth as a percent of GDP—though still higher than the large majority of countries—has declined over the last decade. This trend can be traced back to the turn of the century when China undertook a major restructuring of its state-owned enterprises but left important shortcomings in the intergovernmental fiscal system unaddressed. Compounding these risks, reform momentum stalled in the aftermath of the global financial crisis leading to high leverage and falling profitability among state-owned enterprises.

Assessing the Impact of Policy Changes on a Nowcast
Description: Nowcasting enables policymakers to obtain forecasts of key macroeconomic indicators using higher frequency data, resulting in more timely information to guide proposed policy changes. A significant shortcoming of nowcasting estimators is their “reduced-form” nature, which means they cannot be used to assess the impact of policy changes, for example, on the baseline nowcast of real GDP. This paper outlines two separate methodologies to address this problem. The first is a partial equilibrium approach that uses an existing baseline nowcasting regression and single-equation forecasting models for the high-frequency data in that regression. The second approach uses a non-parametric structural VAR estimator recently introduced in Ouliaris and Pagan (2022) that imposes minimal identifying restrictions on the data to estimate the impact of structural shocks. Each approach is illustrated using a country-specific example.

Constructing a Positive Shock: Growth Through the Lens of Option Pricing
Description: Low-income economies face negative shocks whose frequency and disproportionate impact overcome growth trajectories, producing a negative drift. COVID-19 was the latest such episode. To escape this negative drift, and build a durable recovery, there is a need for a counter-balancing force: to construct a positive shock. Growth is realized through decisions that fall under two categories, routine and non-linear. While routine decisions modify existing economic behavior along the same path, non-linear decisions describe riskier options that involve transformation. Option pricing theory can be useful to describe the latter, and construct the positive shock required to escape the negative drift.
