European Housing Markets at a Turning Point – Risks, Household and Bank Vulnerabilities, and Policy Options
Description: European housing markets are at a turning point as the cost-of-living crisis has eroded real incomes and the surge in interest rates has made borrowers more vulnerable to financial distress. This paper aims to (i) shed light on the risks in European housing markets, (ii) quantify household vulnerabilties, (iii) assess banking sector implications and (iv) examine policies’ effectiveness using simulations based on microdata from the Household Finance and Consumption Survey (HFCS) and EU statistics on income and living conditions (EU-SILC). Under the baseline IMF macroeconomic forecast, the share of households that could struggle to meet basic expenses could rise by 10 pps reaching a third of all households by end 2023. Under an adverse scenario, 45 percent of households could be financially stretched, representing over 40 percent of mortgage debt and 45 percent of consumer debt. The impact on the banking sector seems contained under the baseline forecast, though there are pockets of vulnerability. A 20 percent house price correction could deplete CET1 capital by 100-300 basis points. Fiscal measures, such as subsidies to the bottom income tercile, could save 7 percent of households from financial distress at an estimated cost of 0.8 percent of GDP.

Calibrating Macroprudential Policies in Europe Amid Rising Housing Market Vulnerability
Description: Housing market developments are in the spotlight in Europe. Over-stretched valuations amid tightening financial conditions and a cost-of-living crisis have increased risks of a sustained downturn and exposed challenging trade-offs for macroprudential policy between ensuring financial system resilience and smoothing the macro-financial cycle. Against this backdrop, this paper provides detailed considerations regarding how to (re)set macroprudential policy tools in response to housing-related systemic risk in Europe, providing design solutions to avoid unintended consequences during a tightening phase, and navigating the trade-offs between managing the build-up of vulnerabilities and the macro-financial cycle in a downturn. It also proposes a novel framework to measure the effectiveness of tools and avoid overlaps by quantifying the risks addressed by different macroprudential instruments. Finally, it introduces a taxonomy allowing to assess a country’s macroprudential stance and whether adjustments to current policy settings are warranted—such as the relaxation of capital-based tools and possibly some borrower-based measures in the event of a more severe downturn.

Policy Responses to High Energy and Food Prices
Description: The surge in energy and food prices, which was amplified by Russia’s invasion of Ukraine, has prompted a flurry of policy responses by countries during 2022. The aim of these policy responses was to mitigate social and economic impact of higher prices. In this paper we document announcements of policy measures based on the Database of Energy and Food Price Actions (DEFPA), which was developed based on two rounds of survey responses of IMF country teams conducted in March/April and June/July of 2022. The paper also provides discussion on policy trade-offs when considering appropriate policy responses both for countries with strong and weak social safety nets. Key policy message is that providing targeted support to households in the form of cash transfers is the most cost-effective way of alleviating the burden on vulnerable households and have to be preferred over broad-based mechanisms that prevent international prices to pass through to domestic consumers.

Fragmentation in Global Trade: Accounting for Commodities
Description: We construct a new database which covers production and trade in 136 primary commodities and 24 manufacturing and service sectors for 145 countries. Using this new more granular data, we estimate spillover effects from plausible trade fragmentation scenarios in a new multi-country, multi-sector, general-equilibrium model that accounts for unique demand and supply characteristics of commodities. The results show fragmentation-induced output losses can be sizable, especially for Low-Income-Countries, although the magnitudes vary according to the particular scenarios and modelling assumptions. Our work demonstrates that not accounting for granular commodity production and trade linkages leads to underestimation of the output losses associated with trade fragmentation.

A Deep Dive into Tax Buoyancy: Comparing Estimation Techniques in a Large Heterogeneous Panel
Description: This paper provides new empirical evidence on tax buoyancy (tax revenues responsiveness to changes in economic activity) over the period 1990-2020 using a large panel of 185 countries. This study compares short-term and long-term buoyancy coefficients for total tax revenues and different individual taxes by reviewing and contrasting a range of estimators. Our results broadly confirm the main body of the literature on long-term buoyancy hovering around one. We find evidence of lower estimates for short-term buoyancy relative to previous literature, suggesting a limited automatic stabilization power of taxes. As a robustness exercise, in addition to changes in tax rates, we introduce novel control variables for tax exemptions and bases to disentangle discretionary from automatic tax revenue changes. The marginal changes in the results when controlling for policy actions suggest that, on average, the economic cycle does not necessarily influence tax reforms.

Peering Through the Fog of Uncertainty: Out-of-Sample Forecasts of Post-Pandemic Tourism
Description: This paper uses an augmented gravity model framework to investigate the historical impact of infectious diseases on international tourism and develops an out-of-sample prediction model. Using bilateral tourism flows among 38,184 pairs of countries during the period 1995–2017, I compare the forecasting performance of alternative specifications and estimation methods. These computations confirm the statistical and economic significance of infectious-disease episodes in forecasting international tourism flows. Including infectious diseases in the model improves forecast accuracy by an average of 4.5 percent and as much as 7 percent relative to the standard gravity model. The magnitude of these effects, however, is likely to be much greater in the case of COVID-19, which is a highly contagious virus that has spread fast throughout populations across the world.

Central Bank Digital Currency and Financial Inclusion
Description: In this paper, we develop a model incorporating the impact of financial inclusion to study the implications of introducing a retail central bank digital currency (CBDC). CBDCs in developing countries (unlike in advanced countries) have the potential to bank large unbanked populations and boost financial inclusion which can increase overall lending and reduce bank disintermediation risks. Our model captures two key channels. First, CBDC issuance can increase bank deposits from the previously unbanked by incentivizing the opening of bank accounts for access to CBDC wallets (offsetting potential flows from deposits to CBDCs among those already banked). Second, data from CBDC usage allows for the building of credit to reduce credit-risk information asymmetry in lending. We find that CBDC can increase overall lending if (1) bank deposit liquidity risk is low, (2) the size and relative wealth of the previously unbanked population is large, and (3) CBDC is valuable to households as a means of payment or for credit-building. CBDC can still be optimal for household welfare even when overall lending decreases as households benefit from the value of using CBDC for payments, CBDC provides an alternative "safe" savings vehicle, and CBDC generates greater surplus in lending by reducing credit-risk information asymmetry. Most countries are considering a "two-tier" CBDC model, where central banks issue CBDC to commercial banks which in turn distribute them to consumers. If non-bank payment system providers can distribute CBDC, fewer funds will flow into deposit accounts from the unbanked because a bank account is no longer needed to access CBDC. If CBDC data is shareable with banks, those without bank accounts can still build credit and access lower interest rate loans. This design is optimal for welfare if the gains from greater access to CBDC outweigh the contraction in lending.

Macroeconomic Shocks and Conflict
Description: This paper contributes to the research on the macroeconomic origins of conflict. Based on a sample of 133 low- and middle-income countries over a 30-year period, it analyses to what extent changes in a country’s commodity terms-of-trade (ToT) can explain an increase in the incidence and intensity of conflicts through their effect on aggregate income. While the evidence from previous studies on the link between macroeconomic conditions and conflict is rather inconclusive, we find a significant relationship. Our baseline model finds that a negative commodity ToT shock leads to an increase in the number of conflict events and fatalities. Moreover, the effect plays out over several years albeit with decreasing strength after the second year; and its magnitude is twice as large for Low-Income Countries and Fragile and Conflict-affected States when compared with the sample average. In addition, our results show that macroeconomic shocks are creating more violence in countries with higher inequality and in cases where fiscal policy faces relatively stronger constraints on financing a response to the initial shock to incomes. Our results are robust to a number of plausible variations in model specification. The paper’s results, in conjunction with previous studies that emphasize the economic cost of conflicts, suggest the presence of a fragility trap—a vicious cycle of worsening economic conditions and deteriorating conflicts. Effective policies and well-tailored external financial support could be expected to help countries address this challenge.

Public Debt and Household Inflation Expectations
Description: We use randomized controlled trials in the US, UK, and Brazil to examine the causal effect of public debt on household inflation expectations. We find that people underestimate public debt levels and increase inflation expectations when informed about the correct levels. The extent of the revisions is proportional to the size of the information surprise. Confidence in the central bank considerably reduces the sensitivity of inflation expectations to public debt. We also show that people associate high public debt with stagflationary effects and that the sensitivity of inflation expectations to public debt is considerably higher for women and low-income individuals.

Measurement and Use of Cash by Half the World’s Population
Description: The use of cash for payments is not well measured. We view the value of cash withdrawn from ATMs, or as a share of all payments, as a more accurate and timely measure of cash use compared to the standard measure of currency in circulation, or as a ratio to GDP. These two measures are compared for 14 advanced and emerging market economies. When aggregated, the trend in cash use for payments is currently falling for half the world’s population. Such a measure can help inform policy decisions regarding CBDC and regulatory decisions concerning access to and use of cash.
