Taming Financial Dollarization: Determinants and Effective Policies – The Case of Uruguay
Description: With some of the most significant levels of financial dollarization in the Western Hemisphere, Uruguay is characterized by extensive dollarization in both deposits and loans. While traditional factors like high inflation and substantial devaluations have been associated with such outcome, the enduring nature of dollarization in Uruguay also underscores the importance of structural elements. In formulating a holistic strategy to reduce dollarization, not only should there be an enhancement of the monetary policy framework aimed at maintaining low, stable inflation, but it should also consider the calibration of prudential policies such as currency-differentiated reserve requirements and foreign-currency credit repos.

Monetary Policy Design with Recurrent Climate Shocks
Description: As climate change intensifies, the frequency and severity of climate-induced disasters are expected to escalate. We develop a New Keynesian Dynamic Stochastic General Equilibrium model to analyze the impact of these events on monetary policy. Our model conceptualizes these disasters as left-tail productivity shocks with a quantified likelihood, leading to a skewed distribution of outcomes. This creates a significant trade-off for central banks, balancing increased inflation risks against reduced output. Our results suggest modifying the Taylor rule to give equal weight to responses to both inflation and output growth, indicating a gradual approach to climateexacerbated economic fluctuations.

Mitigating Climate Change at the Firm Level: Mind the Laggards
Description: Using self-reported data on emissions for a global sample of 4,000 large, listed firms, we document large heterogeneity in environmental performance within the same industry and country. Laggards—firms with high emissions relative to the scale of their operations—are larger, operate older physical capital stocks, are less knowledge intensive and productive, and adopt worse management practices. To rationalize these findings, we build a novel general equilibrium heterogeneous-firm model in which firms choose capital vintages and R&D expenditure and hence emissions. The model matches the full empirical distribution of firm-level heterogeneity among other moments. Our counter-factual analysis shows that this heterogeneity matters for assessing the macroeconomic costs of mitigation policies, the channels through which policies act, and their distributional effects. We also quantify the gains from technology transfers to EMDEs.

Predicting the Law: Artificial Intelligence Findings from the IMF’s Central Bank Legislation Database
Description: Using the 2010, 2015, and 2020/2021 datasets of the IMF’s Central Bank Legislation Database (CBLD), we explore artificial intelligence (AI) and machine learning (ML) approaches to analyzing patterns in central bank legislation. Our findings highlight that: (i) a simple Naïve Bayes algorithm can link CBLD search categories with a significant and increasing level of accuracy to specific articles and phrases in articles in laws (i.e., predict search classification); (ii) specific patterns or themes emerge across central bank legislation (most notably, on central bank governance, central bank policy and operations, and central bank stakeholders and transparency); and (iii) other AI/ML approaches yield interesting results, meriting further research.

Estimating Fiscal Multipliers Under Alternative Exchange Rate Regimes: The Case of Bolivia
Description: Empirical (employing the Blanchard-Perotti framework) and modeling (using a country-specific DSGE model) approaches are used to estimate fiscal multipliers by policy instrument for Bolivia, to evaluate possible adjustments in a fiscal consolidation strategy. Multipliers are also estimated using alternative assumptions about the accompanying exchange rate regime and capital mobility, highlighting the importance of the policy mix in determining the impact of fiscal adjustments. The study exploits the DSGE modeling structure to assess this interaction of fiscal and monetary policy in a lower middle-income country under different exchange rate regimes. It finds that expenditure multipliers fall into the range of 1/3 to 2/3, with public investment multipliers slightly higher than government consumption multipliers over longer horizons, and multipliers generally higher under a peg than inflation targeting. Tax multipliers are shown to be about half of expenditure multipliers.

Is FinTech Eating the Bank's Lunch?
Description: This paper examines how the growing presence of FinTech firms affects the performance of traditional financial institutions. The findings point to a negative impact on profitability, primarily due to a reduction in interest income and a rise in operational costs. Although established financial institutions have tried to diversify their revenue streams, these efforts have proven inadequate to offset the losses associated with increased competition from FinTech firms. Our study also reveals that various FinTech business models, such as Peer-to-Peer (P2P) lending and Balance Sheet lending, have varying effects on financial institutions. Cooperative banks experience more significant profit deterioration under both models, whereas (larger) commercial banks appear to benefit from partnerships with P2P platforms, as evidenced by an increase in non-interest income. Furthermore, the findings suggest that FinTech presence has a disproportionately larger adverse effect on banks in countries with more competitive, profitable, and developed financial systems. Interestingly, however, traditional financial institutions in countries with stronger regulatory frameworks appear to benefit from the expanding influence of FinTech firms.

Mobile Money, Perception about Cash, and Financial Inclusion: Learning from Uganda’s Micro-Level Data
Description: Will mobile money render cash less dominant over time in Africa? Can it promote financial inclusion? We shed light on these questions by exploring individual-level and nationally representative survey data for Uganda, a country in a region that pioneered mobile money in the world. We use the Propensity Score Matching method to robustly compare mobile money users and non-users across a range of indicators that capture individuals’ perceptions about cash, and the extent to which they remit, save, and borrow money. We present the first evidence that mobile money users, compared to non-users, are more likely to perceive cash as risky and less likely to prefer carrying large amounts of cash. We also confirm that mobile money users are more likely to receive and send remittances, save, and borrow. They also save and borrow larger amounts.

Currencies of External Balance Sheets
Description: This paper assembles a comprehensive dataset of the currency composition of countries’ external balance sheets for 50 economies over the period 1990–2020. We document the following findings: (i) the US dollar and the euro still dominate global external balance sheets; (ii) there were striking changes in the currency composition across countries since the 1990s, with many emerging markets having moved from short to long positions in foreign currency, thus moving away from the so-called “original sin”; (iii) financial and tradeweighted exchange rates are weakly correlated, suggesting the commonly used trade indices do not adequately reflect the wealth effects of currency movements, and (iv) the large wealth transfers across countries during COVID-19 and the global financial crises increased global imbalances in the former, and reduced them in the latter.

Central Bank Digital Currency and Bank Disintermediation in a Portfolio Choice Model
Description: Would the introduction of a Central Bank Digital Currency (CBDC) lead to lower deposits (disintermediation) and lending in the banking sector? This paper develops a model where households heterogeneous in wealth allocate between an illiquid asset and assets that can be used for payments: bank deposits, cash, and CBDC. CBDC is more efficient as a means of payment and has lower access cost than deposits. Deposits are offered by an imperfectly competitive banking sector which raises deposit interest rates after CBDC introduction to prevent substitution away from deposits to CBDC. We find that there are two opposing margins of impact on the level of aggregate deposits: (1) the intensive margin gain in deposits by richer households increasing their holdings of deposits because of higher interest rates, and (2) the extensive margin loss of deposits among poorer households who switch from deposits to the CBDC. The extensive margin loss in deposits is more likely to dominate (yielding a fall in aggregate deposits) when the mass of poorer households is large and when it is relatively costly to access bank accounts. This tends to be the case in developing and emerging market economies. However, even when the extensive margin loss of deposits dominates and there is disintermediation, the impact on lending is quantitatively small if banks have access to other forms of funding, such as wholesale or central bank financing.

Quantifying the Revenue Yields from Tax Administration Reforms
Description: Despite the criticality of tax administration (TA) reforms in enhancing domestic revenue mobilization, few studies have attempted to quantify the revenue impact of such reforms. This paper fills this gap by estimating the revenue yields associated with various tax administration capabilities, based on the International Survey on Tax Administration (ISORA), the Tax Administration Diagnostic Assessment Tool (TADAT), and TA reform episodes datasets (identified by Akitoby et al., 2020). It uses a Hausman-Taylor cross-country panel regression and an event study for specific TA reform episodes. Our results (using the ISORA data) show that an increase in the overall strength of TA from the 40th percentile to the 60th percentile is associated with an increase in tax revenue by 1.8 pp. of GDP (with a 95 percent confidence range of 0.5‒2.6 pp. of GDP). Similarly, the event-study assessment shows that sustained TA reforms led to an increase in tax revenues between 2 to 3 pp. of GDP, in line with the experience in three country cases (Jamaica, Rwanda, and Senegal). Also, the revenue yields are increasing over time to more than 3 pp. of GDP after the 6th year following a comprehensive reform. The analysis also highlights the significant impact of specific measures including: i) strengthening compliance risks management, ii) enhancing public accountability, iii) establishing Large Taxpayer Offices (LTO), iv) strengthening accountability and transparency, and v) enhancing timely filing of tax declarations.
