The IMF-World Bank Climate Policy Assessment Tool (CPAT): A Model to Help Countries Mitigate Climate Change
Description: To stabilize the climate, global greenhouse gas emissions must be cut by 25 to 50 percent by 2030 compared to 2019. Such an unprecedented rate of decarbonization necessitates climate mitigation policies across countries, notably carbon pricing, fossil fuel subsidy reform, renewable subsidies, feebates, emission rate regulations, and public investments. To design and implement effective, efficient, and equitable policies, governments need tools to assess economic, environmental, fiscal, and social impacts. To support this effort, the IMF and World Bank are making their joint Climate Policy Assessment Tool (CPAT) available to governments. CPAT is a transparent, flexible, and user-friendly model covering over 200 countries. It allows for the rapid quantification of impacts of climate mitigation policies, including on energy demand, prices, emissions, revenues, welfare, GDP, households and industries, local air pollution and health, and many other metrics. This paper describes the CPAT model, its data sources, key assumptions, and caveats.

Central Bank Digital Currency Adoption: A Two-Sided Model
Description: For central bank digital currencies (CBDCs) to accomplish their intended objectives, it is necessary for both consumers to use them and for merchants to accept them. This paper develops a dynamic two-sided payments model with both heterogeneous households and merchants/firms to study: (1) The adoption of CBDC by households and firms, and (2) The impact of CBDC issuance on financial inclusion, informality, and disintermediation. Our model shows that there is a feedback loop where more households will adopt CBDC if more firms accept CBDC and vice versa -- incentivizing both households and firms will result in greater levels of take-up. Households are more likely to adopt CBDC if it is low cost, provides an attractive savings vehicle, reduces the cost of remittances, improves the efficiency of government payments, and (if accepted by merchants) offers a valuable means of payment. Firms are more likely to accept CBDC if fees are low, if there are tax exemptions or subsidies for transactions made in CBDC, and if households who prefer to make payments with CBDC make up a large share of revenue. Upon CBDC issuance, an economy can get stuck at a steady state with low CBDC adoption and small welfare gains if the features of CBDC which do not rely on merchant acceptance (remuneration, efficiency of cross border and government payments) are not sufficiently attractive, or if the households benefiting from these features make up a small share of merchant revenue. Temporary subsidies and using CBDC for government payments can spur initial take-up to transition an economy to a welfare improving steady state with high(er) CBDC usage. Greater adoption of CBDC will result in greater financial inclusion and formalization, but potentially the disintermediation of banks and card payments. Thus, there is a trade-off in designing CBDC for greater adoption. However, the gains are more likely to outweigh the risks in lower income economies with larger unbanked populations and informal sectors.

Firm Leverage and Boom-Bust Cycles
Description: This paper explores the dynamic relationship between firm debt and real outcomes using data from 24 European economies over the period of 2000-2018. Based on macro data, it shows that a rise in credit to firms is associated with an increase in employment growth in the short-term, but employment growth declines in the medium-term. This pattern remains similar, even when the changes in credit to households are accounted for. Next, using data from a large sample of firms, it shows that firm leverage buildups predict similar boom-bust growth cycles in firm employment: Firms with a larger increase in leverage experience a boost in employment growth in the short-term, but employment growth decreases in the medium-term. Relatedly, the volatility of employment growth increases in the aftermath of firm leverage buildups. Finally, this paper provides suggestive evidence on the role of a financial channel in the relationship between firm leverage buildups and employment growth. The results show that a rise in firm leverage is associated with a persistently higher debt service ratio, pointing the drag on finances. Consistently, boom-bust growth cycles in the aftermath of firm leverage buildups are not limited to employment growth, but are also pronounced for investment. Moreover, the medium-term decline in firm employment growth as predicted by leverage buildups becomes even larger if aggregate financial conditions tighten. The findings are in favor of “lean against the wind” approach in policy making.

The Rise of the Walking Dead: Zombie Firms Around the World
Description: We build a new dataset of listed and private nonfinancial zombie firms for a large set of Advanced Economies and Emerging Markets over the last two decades. We find that the share of these unproductive and unviable firms has been rising worldwide, especially since the GFC and the Covid-19 pandemic. We show that, perhaps surprisingly, the incidence of zombification is lower among private firms. Lower average survival rates of private firms may explain this phenomenon. We find important negative macrofinancial spillovers from zombie firms: nonzombies’ financial performance is persistently reduced in industries populated with a greater number of zombies. To mitigate these effects, we document that countries with stronger banks, and tighter macroprudential policies tend to have fewer zombies and stronger nonzombies. Strengthening the banking sector may, however, not be sufficient if insolvency frameworks are not well-prepared to deal with the restructuring or insolvency of firms.

Trading with Friends in Uncertain Times
Description: In this paper we seek to answer the question of how the patterns of bilateral trade are altered by rising trade policy uncertainty (TPU). Specifically, we investigate whether geopolitical alignments between country pairs determine how bilateral trade flows react during periods of greater uncertainty. Using a structural gravity framework augmented with a text-based TPU index and a geopolitical distance measure based on UN General Assembly voting records, we find a significant negative effect of the latter when TPU is elevated, indicating a shift to trading among “friends” in uncertain times.

Some Lessons from Asian E-Money Schemes for the Adoption of Central Bank Digital Currency
Description: This paper synthesizes four lessons from the experiences of six Asian e-money schemes for central banks as they consider adopting central bank digital currency (CBDC): (i) CBDC should embody four attributes: trust, convenience, efficiency, and security; (ii) CBDC service providers can facilitate CBDC adoption through four channels: leveraging digital technology, targeting use cases, developing business models, and complying with legal and regulatory requirements; (iii) central banks could incentivize CBDC service providers to develop these four channels when considering CBDC adoption; and (iv) central banks may be able to establish data-sharing arrangements that preserve privacy while leaving room for CBDC service providers to explore the economic value of data.

Digitalization and Gender Equality in Political Leadership in Sub-Saharan Africa
Description: We examine the impact of digitalization on people’s perceptions of women as political leaders in 34 Sub-Saharan African countries. We find that being a social media or internet user is linked to a higher likelihood of people supporting gender equality in political leadership. However, the intensive margin of usage does not appear to be significant. Furthermore, women’s perceptions of gender equality in political leadership are more sensitive to internet and social media use than men’s. The paper recommends policies for improving ICT infrastructure and investing in technological education.

Bank Competition and Household Privacy in a Digital Payment Monopoly
Description: Lenders can exploit households' payment data to infer their creditworthiness. When households value privacy, they then face a tradeoff between protecting such privacy and credit conditions. We study how the introduction of an informationally more intrusive digital payment vehicle affects households' cash use, credit access, and welfare. A tech monopolist controls the intrusiveness of the new payment method and manipulates information asymmetries among households and oligopolistic banks to extract data contracts that are more lucrative than lending on its own. The laissez-faire equilibrium entails a digital payment vehicle that is more intrusive than socially optimal, providing a rationale for regulation.

Restructuring Reforms for Green Growth
Description: Policymakers across the world are striving to tackle the century-defining challenge of climate change without undermining potential growth. This paper examines the impact of structural reforms in the energy sector (electricity and gas) on enviromental outcomes and green growth indicators in a panel of 25 advanced economies during the period 1970-2020. We obtain striking results. First, while structural reforms so far failed in reducing greenhouse gas emissions per capita, there is some evidence for greater effectiveness in lowering emissions per unit of GDP. Second, although energy reforms are not associated with higher supply of renewable energy as a share of total energy supply, they appear to stimulate a sustained increase in environmental inventions and patents per capita over the medium term. We also find strong evidence of nonlinear effects, with market-friendly energy reforms leading to better environmental outcomes and green growth in countries with stronger environmental regulations. Looking forward, therefore, structural reforms should be designed not just for market efficiency but also for green growth.

Cars and the Green Transition: Challenges and Opportunities for European Workers
Description: Reducing transport sector emissions is an important pillar of the green transition. However, the transition to electric vehicles (EV) portends major changes in vehicle manufacturing activity, on which many livelihoods in Europe depend. Using the heterogeneity across European countries in the speed of transition to EV production and variation in sectoral and regional exposure to the automotive sector, this paper offers early evidence of the labor market implications of the EV transition. Our results suggest that the transformation of the auto sector is already having an adverse impact on employment in the affected sectors and regions, which can be expected to grow at least in the near term. Many of the affected workers will be able to retire and our analysis suggests that those who will have to transition to new “greener” jobs have a fair chance to do so when compared to other workers in the manufacturing sector. Furthermore, we find evidence that active labor market policies, specifically training, can help to reduce the adjustment costs for the affected workers.
