Building Resilience to Natural Disasters: An Application to Small Developing States
Description: We present a dynamic small open economy model to explore the macroeconomic impact of natural disasters. In addition to permanent damages to public and private capital, the disaster causes temporary losses of productivity, inefficiencies during the reconstruction process, and damages to the sovereign's creditworthiness. We use the model to study the debt sustainability concerns that arise from the need to rebuild public infrastructure over the medium term and analyze the feasibility of ex ante policies, such as building adaptation infrastructure and fiscal buffers, and contrast these policies with the post-disaster support provided by donors. Investing in resilient infrastructure may prove useful, in particular if it is viewed as complementary to standard infrastructure, because it raises the marginal product of private capital, crowding in private investment, while helping withstand the impact of the natural disaster. In an application to Vanuatu, we find that donors should provide an additional 50% of pre-cyclone GDP in grants to be spent over the following 15 years to ensure public debt remains sustainable following Cyclone Pam. Helping the government build resilience on the other hand, reduces the risk of debt distress and at lower cost for donors.

Global Liquidity Transmission to Emerging Market Economies, and Their Policy Responses
Description: This paper distills and identifies global liquidity (GL) momenta from the macro-financial data of advanced economies through a factor model with sign restrictions as policy-driven, market-driven, and risk averseness factors. Using a panel factor-augmented VAR, we investigate responses of emerging market economies (EMEs) to GL shocks. A policy-driven liquidity increase boosts growth in EMEs, elevating stock prices and currency values, while a risk averseness rise has an opposite effect. A market-driven GL expansion boosts stock markets and lowers funding costs, promoting competitiveness and current account. Inflation targeting EMEs fare better than EMEs under alternative regimes with respect to macrofinancial volatility.

State-Owned Enterprises in Emerging Europe: The Good, the Bad, and the Ugly
Description: State-owned enterprises (SOEs) play an important role in Emerging Europe’s economies, notably in the energy and transport sectors. Based on a new firm-level dataset, this paper reviews the SOE landscape, assesses SOE performance across countries and vis-à-vis private firms, and evaluates recent SOE governance reform experience in 11 Emerging European countries, as well as Sweden as a benchmark. Profitability and efficiency of resource allocation of SOEs lag those of private firms in most sectors, with substantial cross-country variation. Poor SOE performance raises three main risks: large and risky contingent liabilities could stretch public finances; sizeable state ownership of banks coupled with poor governance could threaten financial stability; and negative productivity spillovers could affect the economy at large. SOE governance frameworks are partly weak and should be strengthened along three lines: fleshing out a consistent ownership policy; giving teeth to financial oversight; and making SOE boards more professional.

The Macroeconomic (and Distributional) Effects of Public Investment in Developing Economies
Description: This paper provides new empirical evidence of the macroeconomic effects of public investment in developing economies. Using public investment forecast errors to identify unanticipated changes in public investment, the paper finds that increased public investment raises output in the short and medium term, with an average short-term fiscal multiplier of about 0.2. We find some evidence that the effects are larger: (i) during periods of slack; (ii) in economies operating with fixed exchange rate regimes; (iii) in more closed economies; (iv) in countries with lower public debt; and (v) in countries with higher investment efficiency. Finally, we show that increases in public investment tend to lower income inequality.

Understanding Correspondent Banking Trends: A Monitoring Framework
Description: The withdrawal of correspondent banking relationships (CBRs) remains a concern for the international community because, in affected jurisdictions, the decline could have potential adverse consequences on international trade, growth, financial inclusion, and the stability and integrity of the financial system. Building on existing initiatives and IMF technical assistance, this paper discusses a framework that can be readily used by central banks and supervisory authorities to effectively monitor the developments of CBRs in their jurisdiction. The working paper explains the monitoring framework and includes the necessary reporting templates and an analytical tool for the collection of data and analysis of CBRs.

Market Reforms at the Zero Lower Bound
Description: This paper studies the impact of product and labor market reforms when the economy faces major slack and a binding constraint on monetary policy easing. such as the zero lower bound. To this end, we build a two-country model with endogenous producer entry, labor market frictions, and nominal rigidities. We find that while the effect of market reforms depends on the cyclical conditions under which they are implemented, the zero lower bound itself does not appear to matter. In fact, when carried out in a recession, the impact of reforms is typically stronger when the zero lower bound is binding. The reason is that reforms are inflationary in our structural model (or they have no noticeable deflationary effects). Thus, contrary to the implications of reduced-form modeling of product and labor market reforms as exogenous reductions in price and wage markups, our analysis shows that there is no simple across-the-board relationship between market reforms and the behavior of real marginal costs. This significantly alters the consequences of the zero (or any effective) lower bound on policy rates.

Lessons from the Old Masters on Assessing Equity and Efficiency: A Primer for Fiscal Policymakers
Description: How can a society’s well-being be measured to include not only average incomes but also their distribution? How can the effects of policies be assessed by considering both equity and efficiency? This primer outlines the seminal contributions of influential economists of the past, including Arthur Okun, who developed a simple method to elicit people’s preferences regarding redistribution, and Anthony Atkinson, who showed how equity and efficiency can be measured simultaneously and summarized in a single, intuitive index expressed in monetary units (such as dollars). These methods are applied to recent data to gauge how countries fare when both mean incomes and their distribution are considered together, and to a hypothetical tax-and-transfer scheme assessed through a general equilibrium model for household-level data.

Loss of Correspondent Banking Relationships in the Caribbean: Trends, Impact, and Policy Options
Description: Banks across the Caribbean have lost important Correspondent Banking Relationships (CBRs). The macroeconomic impact has so far been limited, in part because banks either have multiple relationships or have been successful in replacing lost CBRs. However, the cost of services has increased substantially, some services have been cut back, and some sectors have experienced reduced access. Policy options to address multiple drivers, including lower profitability and risk aversion by global banks, require tailored actions by several stakeholders.

The Adjustment to Commodity Price Shocks in Chile, Colombia, and Peru
Description: This paper presents a comparative analysis of the macroeconomic adjustment in Chile, Colombia, and Peru to commodity terms-of-trade shocks. The study is done in two steps: (i) an analysis of the impulse responses of key macroeconomic variables to terms-of-trade shocks and (ii) an event study of the adjustment to the recent decline in commodity prices. The experiences of these countries highlight the importance of flexible exchange rates to help with the adjustment to lower commodity prices, and staying vigilant in addressing depreciation pressures on inflation through tightening monetary policies. On the fiscal front, evidence shows that greater fiscal space, like in Chile and Peru, gives more room for accommodating terms-of-trade shocks.

FX Intervention in the New Keynesian Model
Description: We develop an open economy New Keynesian Model with foreign exchange intervention in the presence of a financial accelerator mechanism. We obtain closed-form solutions for the optimal interest rate policy and FX intervention under discretionary policy, in the face of shocks to risk appetite in international capital markets. The solution shows that FX intervention can help reduce the volatility of the economy and mitigate the welfare losses associated with such shocks. We also show that, when the financial accelerator is strong, the risk of multiple equilibria (self-fulfilling currency and inflation movements) is high. We determine the conditions under which indeterminacy can occur and highlight how the use of FX intervention reinforces the central bank’s credibility and limits the risk of multiple equilibria.
