Is High Debt Constraining Monetary Policy? Evidence from Inflation Expectations
Description: This paper examines whether high government debt levels pose a challenge to containing inflation. It does so by assessing the impact of government debt surprises on inflation expectations in advanced- and emerging market economies. It finds that debt surprises raise long-term inflation expectations in emerging market economies in a persistent way, but not in advanced economies. The effects are stronger when initial debt levels are already high, when inflation levels are initially high, and when debt dollarization is significant. By contrast, debt surprises have only modest effects in economies with inflation targeting regimes. Increased debt levels may complicate the fight against inflation in emerging market economies with high and dollarized debt levels, and weaker monetary policy frameworks.

Do Sovereign Wealth Funds Reduce Fiscal Policy Pro-cyclicality? New Evidence Using a Non-Parametric Approach
Description: The heightened volatility of commodity prices in recent years, reflecting the effects of the pandemic and the war in Ukraine, begs the longstanding question of the optimal fiscal policy response to commodity price shocks. Fiscal performance in most commodity-exporting countries is typically shaped by shifts in commodity prices and economic activity, often resulting in procyclical fiscal policy. One way to minimize the procyclicality of fiscal policy is to set up a stabilization Sovereign Wealth Fund (SWF). While such funds can help smooth government consumption in good and bad times, the empirical evidence of their value so far has been inconclusive. However, using an unbalanced panel dataset for 182 countries during 1980-2019, with two econometric methods that address the selection-bias problem, we provide robust evidence that stabilization SWFs do indeed help smooth government consumption by reducing fiscal policy volatility associated with commodity price fluctuations.

Foreign Currency Balance Sheets in Türkiye: Exposure and Interconnectedness
Description: As a heavily “dollarized” economy, large foreign currency mismatches exist between institutional sectors within Türkiye, as well as with non-residents. Combining several separate data sources, this working paper builds a picture of the aggregate FX exposure of the total economy. It explores the interlinkages between sectors and how they have evolved in recent years. Since the start of the pandemic, the overall net FX position of the economy deteriorated, and there has also been a considerable shift in FX risk from the private to the public sector. Especially for the central bank, this shift constrains policy space.

Euro Area Inflation after the Pandemic and Energy Shock: Import Prices, Profits and Wages
Description: We document the importance of import prices and domestic profits as a counterpart to the recent increase in euro area inflation. Through a novel consumption deflator decomposition, we show that import prices account for 40 percent of the average change in the consumption deflator over 2022Q1 – 2023Q1, while domestic profits account for 45 percent. The increase in nominal profits was largest in sectors benefiting from increasing international commodity prices and those exposed to recent supply-demand mismatches. While the results show that firms have passed on more than the nominal cost shock, and have fared relatively better than workers, the limited available data does not point to a widespread increase in markups. Looking ahead, assuming nominal wage growth of around 4.5 percent over 2023-24 – slightly below the level seen in Q1 2023 – and broadly unchanged productivity, a normalization of the profit share to the average level over 2015-19 will be necessary to achieve a convergence of inflation to target over the next two years. Monetary policy will thus need to remain restrictive to anchor expectations and maintain subdued demand such that workers and firms settle on relative price setting that is consistent with disinflation.

Sub-Saharan Africa’s Risk Perception Premium: In the Search of Missing Factors
Description: Policymakers from the sub-Saharan Africa (SSA) region often flag a mispricing of their sovereign debt presumably originating from a perception risk by international investors that lead to "unjustifiably" high borrowing costs. Against this background, this paper explores the extent to which a potential SSA premium exists in the financial markets following a broader two-fold approach. Firstly, using a sample of 1592 international primary sovereign fixed coupon bonds issued between 2003-2021 from Bond Radar by 89 countries, we find that SSA countries pay significantly higher coupon at issuance compared to their peers from other regions. Secondly, we assess whether there is any bias against SSA countries in the secondary market that would result in higher refinancing cost. Based on an unbalanced panel of quarterly data covering 107 countries over 1990 – 2022, we find that SSA countries pay higher refinancing costs in the secondary market. The paper further explores whether there are other factors overlooked by the literature that matter for the risk pricing by international investors. In that respect, we explore the sensitivity of spreads to some structural dimensions where SSA countries face acute challenges―the transparency of budget process, the importance of the informal sector, the level of financial development, and the quality of public institutions. The results show that the excess premium estimated for SSA countries vanishes when these structural factors are accounted for in the regressions.

External Shocks, Policies, and Tail-Shifts in Real Exchange Rates
Description: We use panel quantile regressions to study extreme (rather than average) movements in the distribution of the real effective exchange rate (REER) of small open economies. We document that global uncertainty (VIX) and global financial conditions (U.S. monetary policy) shocks have a strong impact on the distribution of the REER changes, with larger impacts in the tails of the distribution, and especially in economies with shallower FX markets, lower central bank credibility, and higher credit risk (i.e., weaker macro fundamentals). Foreign exchange intervention (FXI) partially offsets the impact of these shocks, especially in the left tail (large depreciations) and particularly in economies with weaker fundamentals but, more importantly, when FXI is used sporadically. Thus, our results highlight the importance of deepening FX markets, improving central bank credibility, and strengthening macro fundamentals against the potential dynamic trade-offs of overreliance on a policy that would exacerbate the previously mentioned frictions. While our results point to low effectiveness of capital flow management in preventing large REER movements, they seem to enable more impactful foreign exchange intervention in the immediate aftermath of shocks.

The IMF-World Bank Climate Policy Assessment Tool (CPAT): A Model to Help Countries Mitigate Climate Change
Description: To stabilize the climate, global greenhouse gas emissions must be cut by 25 to 50 percent by 2030 compared to 2019. Such an unprecedented rate of decarbonization necessitates climate mitigation policies across countries, notably carbon pricing, fossil fuel subsidy reform, renewable subsidies, feebates, emission rate regulations, and public investments. To design and implement effective, efficient, and equitable policies, governments need tools to assess economic, environmental, fiscal, and social impacts. To support this effort, the IMF and World Bank are making their joint Climate Policy Assessment Tool (CPAT) available to governments. CPAT is a transparent, flexible, and user-friendly model covering over 200 countries. It allows for the rapid quantification of impacts of climate mitigation policies, including on energy demand, prices, emissions, revenues, welfare, GDP, households and industries, local air pollution and health, and many other metrics. This paper describes the CPAT model, its data sources, key assumptions, and caveats.

Central Bank Digital Currency Adoption: A Two-Sided Model
Description: For central bank digital currencies (CBDCs) to accomplish their intended objectives, it is necessary for both consumers to use them and for merchants to accept them. This paper develops a dynamic two-sided payments model with both heterogeneous households and merchants/firms to study: (1) The adoption of CBDC by households and firms, and (2) The impact of CBDC issuance on financial inclusion, informality, and disintermediation. Our model shows that there is a feedback loop where more households will adopt CBDC if more firms accept CBDC and vice versa -- incentivizing both households and firms will result in greater levels of take-up. Households are more likely to adopt CBDC if it is low cost, provides an attractive savings vehicle, reduces the cost of remittances, improves the efficiency of government payments, and (if accepted by merchants) offers a valuable means of payment. Firms are more likely to accept CBDC if fees are low, if there are tax exemptions or subsidies for transactions made in CBDC, and if households who prefer to make payments with CBDC make up a large share of revenue. Upon CBDC issuance, an economy can get stuck at a steady state with low CBDC adoption and small welfare gains if the features of CBDC which do not rely on merchant acceptance (remuneration, efficiency of cross border and government payments) are not sufficiently attractive, or if the households benefiting from these features make up a small share of merchant revenue. Temporary subsidies and using CBDC for government payments can spur initial take-up to transition an economy to a welfare improving steady state with high(er) CBDC usage. Greater adoption of CBDC will result in greater financial inclusion and formalization, but potentially the disintermediation of banks and card payments. Thus, there is a trade-off in designing CBDC for greater adoption. However, the gains are more likely to outweigh the risks in lower income economies with larger unbanked populations and informal sectors.

Firm Leverage and Boom-Bust Cycles
Description: This paper explores the dynamic relationship between firm debt and real outcomes using data from 24 European economies over the period of 2000-2018. Based on macro data, it shows that a rise in credit to firms is associated with an increase in employment growth in the short-term, but employment growth declines in the medium-term. This pattern remains similar, even when the changes in credit to households are accounted for. Next, using data from a large sample of firms, it shows that firm leverage buildups predict similar boom-bust growth cycles in firm employment: Firms with a larger increase in leverage experience a boost in employment growth in the short-term, but employment growth decreases in the medium-term. Relatedly, the volatility of employment growth increases in the aftermath of firm leverage buildups. Finally, this paper provides suggestive evidence on the role of a financial channel in the relationship between firm leverage buildups and employment growth. The results show that a rise in firm leverage is associated with a persistently higher debt service ratio, pointing the drag on finances. Consistently, boom-bust growth cycles in the aftermath of firm leverage buildups are not limited to employment growth, but are also pronounced for investment. Moreover, the medium-term decline in firm employment growth as predicted by leverage buildups becomes even larger if aggregate financial conditions tighten. The findings are in favor of “lean against the wind” approach in policy making.

Trading with Friends in Uncertain Times
Description: In this paper we seek to answer the question of how the patterns of bilateral trade are altered by rising trade policy uncertainty (TPU). Specifically, we investigate whether geopolitical alignments between country pairs determine how bilateral trade flows react during periods of greater uncertainty. Using a structural gravity framework augmented with a text-based TPU index and a geopolitical distance measure based on UN General Assembly voting records, we find a significant negative effect of the latter when TPU is elevated, indicating a shift to trading among “friends” in uncertain times.
