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.

FINEX - A New Workhorse Model for Macroeconomic Forecasting and Policy Analysis
Description: This paper presents a semi-structural macroeconomic model aimed at facilitating policy analysis and forecasting, primarily in countries with imperfect capital mobility and hybrid monetary policy regimes. Compared to earlier gap-trend projection models, the Forecasting Model of Internal and External Balance (FINEX) contains three main innovations: it accentuates external and internal balances; explicitly incorporates fiscal policy; and partly endogenizes the main trends. FINEX thus covers a broad set of policy instruments, including foreign exchange interventions (FXI), capital flow management measures (CFM), as well as common fiscal policy instruments. The model incorporates insights from the recent DSGE literature, while maintaining a more accessible gap-trend structure that lends itself to practical policy applications. While the paper refrains from drawing broad policy lessons, it emphasizes the model's ability to interpret recent data in terms of structural shocks and policy responses, thereby aiding policymakers in constructing coherent economic narratives and considering alternative scenarios.

Trade Diversion Effects from Global Tensions—Higher Than We Think
Description: The paper builds a unique industry-level dataset by combining Mexico’s nationally sourced inputoutput data (INEGI) with cross-country sources (WIOD, UN Comtrade). Using this dataset to exploit higher supply linkages across a larger number of industries than what is available in cross-country sources, the paper estimates the trade diversion effect on Mexico’s exports to the U.S. from two episodes, with a focus on the first: the U.S.-China trade tension in 2018 and the U.S. sanctions on Russia in 2014. Difference-in-differences, local projections and few other empirical methodologies are used. For the first episode, the paper finds higher trade diversion effects than estimates in literature. Output tariff plays an important role, and there is some evidence of a positive impact through downstream tariffs. The effects are stronger when nationally sourced input-output data is used compared to those derived from cross-country sources. Importantly, the magnitude of trade diversion across industries does not depend on Mexico’s industry-level trade exposure to the U.S., but rather on the U.S. tariff changes on Chinese goods, the decrease in imports from China, product substitutability with Chinese products, and (weakly) on Mexico’s GVC integration. Similarly, for the second episode, the paper finds positive trade diversion effects. Overall, the findings suggest that trade diversion effect might be higher than previously thought and the proper accounting of dataset and supply linkages makes a difference.

The Pass-through of Wages to Consumer Prices in the COVID-19 Pandemic: Evidence from Sectoral Data in the U.S.
Description: We study the pass-through of labor costs to prices using a novel data-set that links industry-level wages to sectoral consumer prices through input-output tables. Pass-through increased during the COVID-19 pandemic recovery, temporarily in goods and persistently in services. Our analysis suggests that the elevated pass-through contributed at least 0.8 percentage points to goods inflation in 2021 and 0.7 percentage points and 0.5 percentage points to services inflation in 2021 and 2022, respectively. We find that the increase in pass-through reflects elevated demand in goods sectors and firms' difficulty in absorbing high wage growth in services sectors. The analysis suggests it will take a reduction in wage growth to bring PCE inflation back to target. Fiscal and monetary policies that help to re-balance the labor markets can facilitate this process.

The Economic Consequences of Social Unrest: Evidence from Initial Public Offerings
Description: Prior research attributes negative stock market performance following episodes of social unrest to elevated uncertainty. However, social unrest does not solely increase uncertainty, but separately acts to decrease investor sentiment. To determine which effect dominates, we study initial public offering (IPO) underpricing, which responds differently to changes to uncertainty and investor sentiment. Consistent with the notion that social unrest dampens investor sentiment, we find robust evidence that IPO first-day returns are lower during times of greater social unrest. Limits to arbitrage intensify the negative relation between social unrest and underpricing. Notably, strong institutional frameworks mitigate the impact of social unrest on underpricing, suggesting that quality institutions weaken the link between investor sentiment and returns.

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.

A New Fiscal Framework for Resource-Rich Countries
Description: This paper revisits the debate on the design of fiscal rules in resource-rich countries. Its main objective is to assess alternative systems of rules against their policy objectives, while taking into account country characteristics. One of the contributions of the paper is to propose fiscal frameworks that are centered around the principle of insurance against shocks and less reliant on estimating precisely resource wealth, which tends to be highly volatile.

A Comprehensive Macroeconomic Uncertainty Measure for the Euro Area and its Implications to COVID-19
Description: This paper develops a new data-driven metric to capture MacroEconomic Uncertainty (MEU) in the euro area. The measure is constructed as the conditional volatility of the unforecastable components of a large set of time series, accounting for the monetary union as well as cross-country heterogeneity. MEU exhibits the largest spike at the time of the COVID-19 outbreak and is noticeably different from other more financial-oriented and policy-driven uncertainty measures. It also reveals a significant increase in inflation uncertainty in 2021-2022. Our BVAR-based analysis shows that an unexpected increase in the MEU has a negative and persistent impact on euro area's industrial production, accounting for 80 percent of its reduction during the first wave of COVID-19, therefore supporting the interpretation of COVID-19 shock as a macroeconomic uncertainty shock. Public debt increases in response to this uncertainty shock. Finally, an increase in MEU negatively affects Emerging Europe countries, contributing the most to the decline in their economic activity during this COVID-19 period.
