Sovereign ESG Bond Issuance: A Guidance Note for Sovereign Debt Managers
Description: This paper aims to provide guidance to issuers of sovereign ESG bonds, with a focus on Emerging Market and Developing Economies (EMDEs). An overview of the ESG financing options available to sovereign issuers is followed by an analysis of the operational requirements and costs that the issuance of sovereign ESG bonds entails. While green bonds are the instruments used to describe the issuance process, the paper also covers alternative instruments, including social and sustainability-linked bonds to provide issuers and other stakeholders with a comprehensive view of the ESG bond marketplace.

Do Capital Controls Limit Inflow Surges?
Description: With rising financial integration, the magnitude and swings in capital flows have increased in the past two decades, intensifying the policy debate on how best to deal with these flows. This paper assesses the use and effectiveness of capital controls in limiting inflow surges. Using a novel dataset on capital control changes across 40 advanced and emerging market and developing economies over 1995-2018, we find that the tightening of capital controls reduces the probability of future surges both at the aggregate and the asset flow levels. The results are robust to various definitions of surges and are stronger when controls are matched to the asset class they target. Finally, we also find significant multilateral spillovers from capital control actions, pointing towards the need for international cooperation in the use of these policies.

Inflation Dynamics in the Western Balkans
Description: After trailing Euro Area inflation closely in the recent past, inflation in the Western Balkans has accelerated faster since early 2022 on the back of the shocks to global commodity prices, strong recovery from the pandemic, and lingering supply bottlenecks. This paper employs two complementary empirical approaches of an augmented Phillips curve and structural VAR, adapting them to the data availability and country specificities of the Western Balkans, to analyze the inflation dynamics in the region. It finds that international food prices affect not only headline but also core inflation as well as inflation expectations. Further, inflation in the Western Balkans is not just determined by foreign shocks, and domestic factors, aggregate demand shocks in particular, have a significant impact on inflation. These findings imply a possible role for policies to temporarily limit an immediate and complete pass-through of international to domestic food prices while also stressing the importance of an appropriate domestic macroeconomic policy mix to keep inflation expectations anchored and safeguard credibility in the face of high inflation persistence.

Capital Account Liberalization and Wage Inequality: Evidence from Firm Level Data
Description: Firms play an important role in shaping income inequality at the aggregated country level, given that wages represent a significant proportion of household income. We investigate the distributional consequences of capital account liberalization, relying on firm level data to explore the implications for betweenfirms earning inequality in ASEAN5 countries over the period 1995-2019. We find that between-firms wage dispersion alone, accounts for a nontrivial proportion of the variation in the market Gini. Our empirical findings show that capital account liberalization increases between-firms wage inequality, as wages grow faster at initially high-paying firms and slow-down at firms at the lower portion of the wage distribution. These results are robust to a battery of robustness checks. Further, the directions and categories of capital account liberalization matter as results are pronounced for inflow liberalization and equity capital flows. We also show that capital account liberalization induces an increase in Profit-to-Wage ratios. Furthermore, the impact depends on country characteristics (wage setting institutions, the level of financial development and the size of the informal sector) as well as industry characteristics (export orientation and external finance dependence).

2022 Update of the External Balance Assessment Methodology
Description: The assessment of external positions and exchange rates of member countries is a key mandate of the IMF. The External Balance Assessment (EBA) methodology has provided the framework for conducting external sector assessments by Fund staff since its introduction in 2012. This paper provides the latest version of the EBA methodology, updated in 2022 with additional refinements to the current account and real exchange rate regression models, as well as updated estimates for other components of the EBA methodology. The paper also includes an assessment of how estimated current account gaps based on EBA are associated with future external adjustment.

Unbearable Costs: When Is Inflation Impeding Job Creation? Evidence from Sub-Saharan Africa
Description: Covid-19 and war-induced commodity price fluctuations, and broadening price pressures have led to a surge in inflation in many sub-Saharan Africa (SSA) countries. To adjust to increasing costs, firms have resorted to several measures including shuttering offices, reducing businesses, laying off, and freezing hiring, thus putting at risk job creation and raising concerns of youth unemployment. This paper explores the effects of inflation on private employment growth in SSA using a large firm -level dataset from the World Bank’s Enterprise Surveys. We find a non-linear relationship between inflation and job creation in SSA, with job creation being negatively correlated with inflation rate when the latter is above 14 percent. This finding holds regardless of the sector of activities of firms and the exchange rate regime. In addition, the paper finds some differential effects based on the type of products. An increase in fuel prices tends to be more detrimental to job creation than food prices. The study also provides evidence that the state of implementation of structural reforms matters. The results show that inflation reduces job opportunities mostly in countries with bad or no structural reforms.

Identifying Optimal Indicators and Lag Terms for Nowcasting Models
Description: Many central banks and government agencies use nowcasting techniques to obtain policy relevant information about the business cycle. Existing nowcasting methods, however, have two critical shortcomings for this purpose. First, in contrast to machine-learning models, they do not provide much if any guidance on selecting the best explantory variables (both high- and low-frequency indicators) from the (typically) larger set of variables available to the nowcaster. Second, in addition to the selection of explanatory variables, the order of the autoregression and moving average terms to use in the baseline nowcasting regression is often set arbitrarily. This paper proposes a simple procedure that simultaneously selects the optimal indicators and ARIMA(p,q) terms for the baseline nowcasting regression. The proposed AS-ARIMAX (Adjusted Stepwise Autoregressive Moving Average methods with exogenous variables) approach significantly reduces out-of-sample root mean square error for nowcasts of real GDP of six countries, including India, Argentina, Australia, South Africa, the United Kingdom, and the United States.

Differential Effects of Macroprudential Policy
Description: We explore the differential effects of lender-based macroprudential policies on new mortgage borrowing for households of different income using a comprehensive dataset that links macroprudential policy actions with household survey data for European Union countries. The main results suggest that higher-income households on average experience a larger reduction in mortgage loan size than lower-income households when regulation targeting total lenders’ assets tightens. In contrast, lower-income households on average experience a larger reduction in mortgage loan size than higher-income households when regulation targeting lenders’ capital requirements tightens. We also provide evidence of the different channels through which the differential effects operate.

Global Supply Chain Disruptions: Challenges for Inflation and Monetary Policy in Sub-Saharan Africa
Description: The Covid-19 pandemic has led to a large disruption of global supply chains. This paper studies the implications of supply chain disruptions for inflation and monetary policy in sub-Saharan Africa. Increases in supply chain pressures have had a sizeable impact on headline, food, and tradable inflation for a panel of 29 sub-Saharan African countries from 2000 to 2022. Our findings suggest that central banks can stabilize inflation and output more efficiently by monitoring global supply chains and adjusting the monetary policy stance before the disruptions have fully passed through into all inflation components. The gains from monitoring supply chain disruptions are particularly large for open economies which tend to experience outsized second-round effects on the prices of non-tradable goods and services.

Guaranteeing Trade in a Severe Crisis: Cash Collateral over Bank Guarantees
Description: Banks guarantee international trade through letters of credit. This paper analyzes what happens to trade when the critical role of banks as trade guarantors is compromised. Using the case of the Greek capital controls in 2015, the events around which led to a massive loss of confidence in the domestic banking system, we show that firms whose operations were more dependent on domestic banks suffered a steep decline in imports and, subsequently, exports. This operated through letters of credit, which during the capital controls period had to be backed by firms’ own cash collateral rather than the bank guarantee. As a result, cash-poor firms imported relatively less. Public intervention to guarantee transactions is shown to help mitigate some of the decline in imports.
