Informality and the Challenge of Pension Adequacy: Outlook and Reform Options for Peru
Description: Past reforms have put the Peruvian pension system on a largely fiscally sustainable path, but the system faces important challenges in providing adequate pension levels for a large share of the population. Using administrative microdata at the affiliate level, we project replacement rates in the defined benefit (DB) and defined contribution (DC) pillars over the next 30 years and simulate the impact of various reform scenarios on the average level and distribution of pensions. In the DB pillar, the regressive minimum contribution period should be re-thought, while in the DC pillar a broadening of the contribution base and/or an increase in contribution rates would help increase replacement rates relative to the baseline forecast of 25-33 percent. A higher net real rate of return than assumed in the baseline would also have a significant positive impact. In the medium-term, labor market reform to tackle informality, and a broad pension reform to restructure the system and avoid competition between the DB and DC pillars should be a priority. Given low pension coverage, having a strong non-contributory pillar will remain important for the foreseeable future.

Income Inequality and Government Transfers in Mexico
Description: We analyze microdata from Mexico's survey on household income and expenditures (ENIGH) to study the evolution of income inequality in Mexico over 2004-16, identify its sources, and investigate how it was affected by government social policy. We find evidence of only a small decline in inequality over this period. The observed decline may be attributed to government transfers, notably targeted cash transfers (Prospera) and non-contributory pensions. In 2016, those two programs accounted for more than two thirds of the reduction in the Gini coefficient due to government transfers. Other transfer programs such as farmland subsidies (Proagro), government scholarships, and non-monetary transfers for medical expenditures have not been as effective.

Inflation Co-Movement in Emerging and Developing Asia: The Monsoon Effect
Description: Co-movement (synchronicity) in inflation rates among a set of 13 emerging and developing countries in Asia is shown to be strongest for the food component, partly due to common rainfall shocks—a result which the paper terms the ‘monsoon effect.’ Economies with higher trade integration and co-movement in nominal effective exchange rates also experience greater food-inflation co-movement. By contrast, cross-country co-movement in core inflation is weak and the aforementioned determinants have little explanatory power, suggesting a prominent role for idiosyncratic domestic factors in driving core inflation. In the context of the growing literature on the globalization of inflation, these results suggest that common weather patterns are partly responsible for any role played by a so-called ‘global factor’ among inflation rates in emerging and developing economies, in Asia at least.

Drivers of Cross-Border Banking in Sub-Saharan Africa
Description: Using data collected from pan-African banks’ (PABs), balance sheets and other sources (Orbis, Fitch), this study identifies some key patterns of cross-border investment in bank subsidiaries by key banking groups in sub-Saharan Africa (SSA) and discusses some of the determinants of this investment. Using a gravity model relating the annual value of a banking group’s investment in the net equity of its subsidiaries to a set of explanatory variables, the analysis finds that cross-border banking is in part driven by a search for yield, diversification, and expansion for strategic reasons.

Climate Disaster Risks – Empirics and a Multi-Phase Dynamic Model
Description: Recent research in financial economics has shown that rare large disasters have the potential to disrupt financial sectors via the destruction of capital stocks and jumps in risk premia. These disruptions often entail negative feedback e?ects on the macroecon-omy. Research on disaster risks has also actively been pursued in the macroeconomic models of climate change. Our paper uses insights from the former work to study disaster risks in the macroeconomics of climate change and to spell out policy needs. Empirically the link between carbon dioxide emission and the frequency of climate re-lated disaster is investigated using cross-sectional and panel data. The modeling part then uses a multi-phase dynamic macro model to explore this causal nexus and the e?ects of rare large disasters resulting in capital losses and rising risk premia. Our proposed multi-phase dynamic model, incorporating climate-related disaster shocks and their aftermath as one phase, is suitable for studying mitigation and adaptation policies.

Explaining High Unemployment in ECCU Countries
Description: In recent years, unemployment rates in some ECCU countries have been among the highest globally. This paper evaluates several factors that could explain them, finding that high unit labor costs, in a context of strong unionization, are significantly associated with high structural unemployment, while the global crisis added a cyclical component. Our analysis also suggests that high-paid jobs in the public and tourism sectors, which have been growing considerably in recent decades, could have increased the reservation wage and lowered labor force participation. We find no indication that high structural unemployment is related to the phase out of EU preferences on bananas/sugar exports or to a skills mismatch. As expected, unemployment has been substantially, but only temporarily fueled by large natural disasters.

Trade Wars and Trade Deals: Estimated Effects using a Multi-Sector Model
Description: This paper studies the potential long-term effects of three illustrative scenarios using a multi-sector computable general equilibrium (CGE) trade model calibrated to 165 countries. The first scenario estimates effects from potential U.S. auto tariffs. The second analyzes a ‘transactional deal’ between the U.S. and China to close their bilateral deficit. The third, in the absence of such a deal, considers a potential escalation in bilateral tariffs between the two countries. Some common features emerge across all three scenarios: the overall effects on GDP tend to be relatively small albeit negative in most cases, including for the U.S. However, sectoral disruptions and positive and negative spillovers to highly exposed ‘by-stander’ economies can be large. There is also heterogeneity at the subnational level in the U.S. -- richer states tend to benefit from certain scenarios. We discuss how estimated impacts depend on the extent to which the U.S. is able to re-shore production in protected sectors. These results can usefully complement estimates obtained through macroeconomic models that are better suited to capture dynamic effects, such as those stemming from trade policy uncertainty. More generally, our results both underscore the value of adhering to the existing levels of liberalization, and highlight the risks associated with a fragmentation or even a complete breakdown of the trading system.

Technological Changes, Offshoring, and the Labor Share
Description: Existing studies on the downward trend in the labor share of income mostly focus on changes within individual countries. I document, however, that half of the global decline in the labor share of income can be traced to the relocation of activities between countries. I develop a two-country model to show that when the relative price of investment goods falls, production activities with a small elasticity of substitution between capital and labor tend to get offshored from high- to low-wage countries. The model provides an explanation as to why such relocation may drive the labor share down in both developed and developing economies, as well as globally.

The Rewards of Fiscal Consolidation: Sovereign Spreads and Confidence Effects
Description: This paper investigates the effects of fiscal consolidation announcements on sovereign spreads in a panel of 21 emerging market economies during 2000-18. We construct a novel dataset using a global news database to identify the precise announcement date of fiscal consolidation actions. Our results show that sovereign spreads decline significantly following news that austerity measures have been approved by the legislature (congress or parliament), in periods of high sovereign spreads or in countries under an IMF program. In addition, consolidation announcements are less contractionary when sovereign spreads decline, with the reduction in output being half of the counterfactual case in which spreads do not respond to announcements. These results constitute direct evidence that confidence effects, in the form of lower sovereign spreads, are an important transmission channel of fiscal shocks. We also find that the role of confidence effects increases with the level of spreads such that countries with high spread levels stand to benefit the most from putting in place credible austerity packages.

Public Wealth in the United States
Description: We analyze the US public sector balance sheet and project it forward under the assumption that current policies remain in place. We first document the history of the balance sheet and its components since World War II, with a detailed account of its evolution during and after the global financial crisis. While, based on assets and liabilities alone, public sector net worth is negative, additional challenges arise from commitments to future spending implied by current legislation and demographic trends. To quantify the risks to the balance sheet, we then apply the macroeconomic scenarios from the Federal Reserve’s bank stress test to the public sector balance sheet.
