Sustainable Finance in Emerging Markets: Evolution, Challenges, and Policy Priorities
Description: Sustainable finance has become a key focus area for global investors and policy makers. Last year proved to be a breakout year for emerging markets (EMs), with sustainable debt issuance in 2021 surging to almost $200 billion. This working paper, the first comprehensive study in the literature, analyzes the evoluiton of EM sustainable finance markets, including differences with advanced economies. The analysis shows how sustainable finance in EMs is growing fast not just in aggregate but importantly across many dimensions. The paper also identifies key development areas for EMs and policies to strengthen the resilience of sustainable finance markets.

Determinants of Inflation in Iran and Policies to Curb It
Description: High and volatile inflation has been an endemic economic and social issue in Iran that has contributed to rising poverty and social tensions. For policymakers to effectively address the inflation problem, it is critical to understand its causes. This paper seeks to contribute to this endeavor by applying a vector error-correction model to study the short- and long-term determinants of inflation in Iran over the past two decades and identify policy options to curb it. Using quarterly data spanning 2004-2021, it finds that money growth drives inflation only in the long term, while currency depreciation, fiscal deficits, and sanctions (proxied by oil exports) drive inflation both in the short- and the long term. In the absence of a removal of US trade and financial sanctions that could significantly boost the rial, budget deficits will have to be adjusted to contain inflation, albeit gradually to avoid hindering the recovery. Over the medium term, strengthening the inflation targeting framework could help improve monetary transmission and contain inflation durably.

Closing Peru's Ethnic Gaps Amidst Sustained Economic Growth
Description: We analyze the recent evolution of ethnic economic inequality in Peru, a major source of social discontent in the country. Household survey data indicates that recent decades of high output growth also witnessed a substantial narrowing of socioeconomic gaps among ethnicities. Most notably, the Mestizo ethnic group surpassed the White group in income per capita, and Native American also experienced a relative improvement. Mincerian regression analysis suggests that the main contributors to these developments were rural-to-urban migration and increased education. Based on our statistical findings, we propose enhancing education and other public services, increasing government revenues, lowering informality, and promoting competition as the main public policies that could accelerate the ongoing narrowing of ethnic gaps.

Waiting for Godot? The Case for Climate Change Adaptation and Mitigation in Small Island States
Description: Global warming is the most significant threat to ecosystems and people’s health and living standards, especially in small island states in the Caribbean and elsewhere. This paper contributes to the debate by analyzing different options to scale up climate change mitigation and adaptation. In particular, the empirical analysis indicates that increasing energy efficiency and reducing the use of fossil fuel in electricity generation could lead to a significant reduction in carbon emissions, while investing in physical and financial resilience would yield long-run benefits. From a risk-reward perspective, the advantages of reducing the risks associated with climate change and the health benefits from higher environmental quality clearly outweigh the potential cost of climate change mitigation and adaptation in the short run. The additional revenue generated by environmental taxes could be used to compensate the most vulnerable households, building a multilayered safety net, and strengthening structural resilience.

Dirty Dance: Tourism and Environment
Description: Tourism was one of the fastest-growing sectors before the COVID-19 pandemic, accounting for about 10 percent of global GDP. But it has also created a number of challenges including environmental degradation, especially in small island countries where the carbon footprint of tourism constitute substantial share of carbon dioxide (CO2) emissions. This study empirically investigates the impact of tourism on CO2 emissions in a relatively homogenous panel of 15 Caribbean countries over the period 1960–2019. The results show that international tourist arrivals have a statistically and economically significant effect on CO2 emissions, after controlling for other economic, institutional and social factors. Therefore, managing tourism sustainably requires a comprehensive set of policies and reforms aimed at reducing its impact on environmental quality and curbing excessive dependency on fossil fuel-based energy consumption.

Private Savings and COVID-19 in Sub-Saharan Africa
Description: The paper reexamines the main private savings determinants in Sub-Saharan Africa (SSA), followed by an analysis of the COVID-19 pandemic impact on private savings in SSA and other country groupings. Using an unbalanced panel data from 1983−2021 for 31 SSA economies, the paper finds that real per capita economic growth remains a key historical determinant of private savings in the region. In contrast with other regions, private saving rates have not increased during COVID-19 in SSA. Instead, COVID-19 deaths in our estimations are significantly associated with a decline in private savings in SSA. Robustness checks and a descriptive analysis of household surveys during the pandemic corroborate those results.

The Fear Economy: A Theory of Output, Interest, and Safe Assets
Description: This paper presents a fear theory of the economy, based on the interplay between fear of rare disasters and the interest rate on safe assets. To do this, I study the macroeconomic consequences of government-administered interest rates in the neoclassical real business cycle model. When the government has the power to fix the safe real interest rate, the gap between the `sticky real safe rate' and the `neutral rate' can generate far-reaching aggregate distortions. When fear exogenously rises, the demand for safe assets rise and the neutral rate falls. If the central bank does not lower the safe rate by the same amount, savings rise leading to a decline in consumption and aggregate demand. The same mechanism works in reverse, when fear falls. Quantitatively, I show that a single fear factor can simultaneously (i) generate cross-correlations in output, labor, consumption, and investment consistent with the postwar US economy; and (ii) generates variation in equity prices, bond prices, and a large risk premium in line with the asset pricing data. Six novel insights emerge from the model: (1) actively regulating the safe interest rate (in both directions) can mitigate the fluctuations generated by fear cycles; (2) recessions will be deeper and longer when central banks accept the zero lower bound and are unwilling to use negative rates; (3) a commitment to use negative rates in recessions—even if never implemented—raises both the short- and long-run real neutral rates, and moderates the business cycle; (4) counter-cyclical fiscal policy can act as disaster insurance and be expansionary by reducing fear; (5) quantitative easing can be narrowly effective only when fear is high at the lower bound; and (6) when fear is high, especially at the lower bound, policies that boost productivity also help fight recessions.

Climate Change and Energy Security: The Dilemma or Opportunity of the Century?
Description: This paper investigates the connection between climate change and energy security in Europe and provides empirical evidence that these issues are the two faces of the same coin. Using a panel of 39 countries in Europe over the period 1980–2019, the empirical analysis presented in this paper indicates that increasing the share of nuclear, renewables, and other non-hydrocarbon energy and improving energy efficiency could lead to a significant reduction in carbon emissions and improve energy security throughout Europe. Accordingly, policies and reforms aimed at shifting away from hydrocarbons and increasing energy efficiency in distribution and consumption are key to mitigating climate change, reducing energy dependence, and minimizing exposure to energy price volatility.

What Matters for Job Finding and Separation in the Long Run? Evidence from Labor Market Dynamics in New Zealand
Description: We use the novel anonymized Household Labour Force Survey (HLFS) microdata to analyze job finding rates and job separation rates in New Zealand. We find that individual characteristics, including age, gender, ethnicity and education have a significant impact on job finding and separation rates, even after controlling for other factors. We use a decomposition approach to analyze how the effects of individual characteristics on job finding and separation rates contribute to heterogeneity in employment outcomes. Overall, we find that higher separation rates of young workers play a disproportionate role in explaining heterogeneity of employment outcomes across age groups, while differences in finding rates are somewhat more important in explaining differences by education level. Both finding and separation rate differences are important in explaining differences across ethnicities. We also find some heterogeneous response of worker groups to business cycle after controlling for other factors. The results underscore the importance of well-targeted labor market support policies.

Mind the Gap: City-Level Inflation Synchronization
Description: The post-pandemic rise in consumer prices across the world has renewed interest in inflation dynamics after decades of global disinflation. This paper provides a spatial investigation of inflation synchronicity at the city level in Lithuania using disaggregated monthly data during the period 2000–2021. The empirical analysis provides strong evidence that (i) the co-movement of city-level inflation rates—estimated using the instantaneous quasi-correlation approach—is significantly weaker than the extent of synchronization suggested by the simple correlation analysis; (ii) there is substantial heterogeneity in the instantaneous quasi-correlation of inflation subcomponents between city pairs; and (iii) there are significant changes in the degree of city-level synchronization over time, reflecting important economic developments in history such as the global financial crisis, the adoption of euro, and the COVID-19 pandemic.
