The Distributional Impact of a Carbon Tax in Asia and the Pacific
Description: While a carbon tax is widely acknowledged as an efficient policy to mitigate climate change, adoption has lagged. Part of the challenge resides in the distributional implications of a carbon tax and a belief that it tends to be regressive. Even when not regressive, poor households could be hurt by a carbon tax, particularly in countries that rely heavily on carbon-intensive energy sources. Using household surveys, we study how a carbon tax may affect households in the Asia Pacific region, the main source of CO2 emissions. We document a wide range of country-specific policies that could be implemented to compensate households, reduce inequality, and build support for adoption.

The International Diffusion of Policies for Climate Change Mitigation
Description: In this paper, we study the international diffusion of carbon pricing policies. In the first part, we empirically examine to what extent the adoption of carbon pricing in a given country can explain the subsequent adoption of the same policy in other countries. In the second part, we quantify the global benefits of policy diffusion in terms of greenhouse gas emission reductions elsewhere. To do so, we combine a large international dataset on carbon pricing with several other datasets. For causal identification, we estimate semi-parametric Cox proportional hazard models. We find robust and statistically significant evidence for policy diffusion.

Tracking Economic and Financial Policies During COVID-19: An Announcement-Level Database
Description: We introduce a new comprehensive announcement-level database tracking the extraordinary fiscal, monetary, prudential, and other policies that countries adopted in response to Covid-19. The database provides detailed information, including sizes where available, for 28 granular policies adopted by 74 countries during 2020. About 5,500 policy measures were announced during this period. Importantly, the database is organized and presented in a format easy for researchers to use in empirical analyses. Announcements were highly correlated across the broad fiscal, monetary, and prudential categories and at more granular levels. Advanced economies (AEs) introduced larger fiscal measures than emerging and developing economies (EMDEs) and relied primarily on large unconventional monetary policies. Bank capital requirements were relaxed widely in both AEs and EMs, while relaxation of provisioning requirements was more common among EMs. Supervisory expectations and reporting requirements were widely relaxed.

Quantitative Easing and Credit Rating Agencies
Description: This paper investigates the behaviour of credit rating agencies using a natural experiment in monetary policy. We exploit the corporate QE of the Eurosystem and its rating-based specific design which generates exogenous variation in the probability for a bond of becoming eligible for outright purchases. We show that after the launch of the policy, rating activity was concentrated precisely on the territory where the incentives of market participants are expected to be more sensitive to the policy design. Our findings contribute to better assessing the consequences of the explicit reliance on CRAs ratings by central banks when designing monetary policy. They also support the Covid-19 monetary stimulus, and in particular the waiver of private credit rating eligibility requirements applied to recently downgraded issuers.

Monetary Policy and Exchange Rate Dynamics in a Behavioral Open Economy Model
Description: We develop an extension of the open economy New Keynesian model in which agents are boundedly rational à la Gabaix (2020). Our setup nests rational expectations (RE) as a special case and it can successfully mitigate many “puzzling” aspects of the relationship between exchange rates and interest rates. Since the model implies an uncovered interest rate parity (UIP) condition featuring behavioral expectations, our results are also consistent with recent empirical evidence showing that several UIP puzzles vanish when actual exchange rate expectations are used (instead of realizations implicitly coupled with the RE assumption). We find that cognitive discounting dampens the effects of current monetary shocks and lowers the efficacy of forward guidance (FG), but its relative importance in mitigating the so-called FG puzzle is decreasing in openness. Finally, we show that accounting for myopia exacerbates the small open economy unit-root problem, makes positive monetary spillovers more likely, and increases the persistence of net foreign assets and the real exchange rate.

Fiscal Decentralization Improves Social Outcomes When Countries Have Good Governance
Description: Does fiscal decentralization improve health and educational outcomes? Does this improvement depend on the quality of governance? How do fiscal decentralization and governance interact? We answer these questions through an instrumental variable Tobit analysis of cross-country panel data. We find negative effects of fiscal decentralization on health outcomes, which however are more than offset by better governance. Education expenditure decentralization to subnational governments enhances educational outcomes. We conclude that countries can only reap the benefits from decentralization when the quality of their governance arrangements exceeds a certain threshold. We also find that sequencing and staging of decentralization matter. Countries should improve government effectiveness and control of corruption first to maximize benefits of fiscal decentralization.

Systematizing Macroframework Forecasting: High-Dimensional Conditional Forecasting with Accounting Identities
Description: Forecasting a macroframework, which consists of many macroeconomic variables and accounting identities, is widely conducted in the policy arena to present an economic narrative and check its consistency. Such forecasting, however, is challenging because forecasters should extend limited information to the entire macroframework in an internally consistent manner. This paper proposes a method to systematically forecast macroframework by integrating (1) conditional forecasting with machine-learning techniques and (2) forecast reconciliation of hierarchical time series. We apply our method to an advanced economy and a tourism-dependent economy using France and Seychelles and show that it can improve the WEO forecast.

Measuring Quarterly Economic Growth from Outer Space
Description: This paper presents a novel framework to estimate the elasticity between nighttime lights and quarterly economic activity. The relationship is identified by accounting for varying degrees of measurement errors in nighttime light data across countries. The estimated elasticity is 1.55 for emerging markets and developing economies, ranging from 1.36 to 1.81 across country groups and robust to different model specifications. The paper uses a light-adjusted measure of quarterly economic activity to show that higher levels of development, statistical capacity, and voice and accountability are associated with more precise national accounts data. The elasticity allows quantification of subnational economic impacts. During the COVID-19 pandemic, regions with higher levels of development and population density experienced larger declines in economic activity.

Fintech, Female Employment, and Gender Inequality
Description: Fintech, which delivers financial services digitally, promises to promote financial inclusion and close the gender gap. Using a novel fintech dataset for 114 economies worldwide, this paper shows that fintech adoption significantly improves female employment and reduces gender inequality, the effect being more pronounced in firms without traditional financial access. Fintech not only increases the number and ratio of female employees in the workforce, but also mitigates financial constraints of female-headed firms. Digital divide and poor institutions weaken such benefits. Endogeneity is accounted for by a fixed effects identification strategy. We conclude by providing policy recommendations and outlining avenues for future research.

The Great Carbon Arbitrage
Description: We measure the gains from phasing out coal as the average social cost of carbon times the quantity of avoided emissions. By comparing the present value of benefits from avoided emissions against the present value of costs of ending coal and replacing it with renewables, our conservative baseline estimate is that the world can realize a net gain of $85 trillion. This global net social benefit can be attained through an international agreement to phase out coal. We also explore how this net benefit is distributed across countries and find that most countries would benefit from a global coal phase-out even without any compensatory cross-country transfers. Finally, we estimate the size of public funds that must be committed under a blended finance arrangement to finance the cost of replacing coal with renewables.
