Dining and Wining During the Pandemic? A Quasi-Experiment on Tax Cuts and Consumer Spending in Lithuania
Description: Could temporary tax cuts stimulate consumer spending? Sector-specific measures to the COVID-19 pandemic provides a quasi-experimental variation in consumption patterns to infer a causal effect of tax policy changes. Using a novel dataset of daily debit and credit card transactions, this paper investigates the effectiveness of Lithuania’s decision to cut the standard value-added tax (VAT) rate from 21 percent to 9 percent on restaurants and catering services during the pandemic in a difference-in-differences regression framework. I obtain robust evidence that the VAT reduction has had no statistically significant impact on consumer spending on restaurants and catering services, while other policy interventions such as mobility restrictions and vaccination have more pronounced effects. These results have important policy implications in terms of the expected stimulative effect of sector-specific VAT reductions and the effective design of fiscal policy interventions to counter the impact of pandemics during which mobility is highly constrained.

The Role of Structural Fiscal Policy on Female Labor Force Participation in OECD Countries
Description: This paper examines the role of structural fiscal policies to promote female labor force participation and reduce gender gaps in labor markets in 26 OECD countries from 2000 to 2019. As both female labor force participation and many explanatory/control variables clearly exhibit non-stationarity (potentially leading to spurious regression results), we employ a panel vector error-correction model, in contrast with most previous empirical studies on this matter. Our analyses confirm statistically significant positive impacts of government spending on (1) early childcare and education, (2) active labor market programs, and (3) unemployment benefits, all of which would help encourage women to enter the labor force, while (4) an increase in relative tax rate on second earner could have negative impact on female labor force participation.

Global Economic Impacts of Physical Climate Risks
Description: This paper evaluates the global economic consequences of physical climate risks under two Shared Socioeconomic Pathways (SSP 1-2.6 and SSP 2-4.5) using firm-level evidence. Firstly, we estimate the historical sectoral productivity changes from chronic climate risks (gradual changes in temperature and precipitation) and extreme climate conditions (representative of heatwaves, coldwaves, droughts, and floods). Secondly, we produce forward-looking sectoral productivity changes for a global multisectoral sample of firms. For floods, these estimates account for the persistent productivity changes from the damage to firms’ physical capital. Thirdly, we assess the macroeconomic impact of these shocks within the global, multisectoral, intertemporal general equilibrium model: G-Cubed. The results indicate that, in the absence of additional adaptation relative to that already achieved by 2020, all the economies would experience substantial losses under the two climate scenarios and the losses would increase with global warming. The results can be useful for policymakers and practitioners interested in conducting climate risk analysis.

Good Supervision: Lessons from the Field
Description: Keeping banks safe and sound hinges on good supervision. The bank failures of March 2023 precipitated questions about the effectiveness of supervision. This paper reflects on lessons learned from this banking turmoil and reviews global progress in delivering effective supervision over the past ten years. It finds progress in areas like risk monitoring, stress testing, and business model analysis. Yet, progress has also been hampered by deficiencies in supervisory approaches, techniques, tools, and (use of) corrective and sanctioning powers, as well as by unclear mandates, inadequate powers, and lack of independence and resources. Overcoming these deficiencies requires supervisors to improve their own performance and other policy makers to contribute to ensuring vigilant, independent and accountable supervision.

Environmental Policies and Innovation in Renewable Energy
Description: This paper investigates the effect of Climate Change Policies (CCPs) on green innovation, for a sample of 40 advanced and emerging market economies and 5 economic sectors, during the period 2000-2021. Our results suggest that CCPs increase green patents, with the effect increasing gradually over time. The effect is larger for non-market-based policies—such as R&D subsidies—and technology-support instruments, in countries with greater competitiveness and during periods of stronger economic activity—that is, higher GDP growth, lower uncertainty and financial stress. The results based on a difference-in-differences approach suggest that the positive effect of stricter CCPs on green innovation is stronger in sectors with limited financial constraints.

Modeling the Reserve Demand to Facilitate Central Bank Operations
Description: Implementing monetary policy largely consists in controlling short-term interest rates which supposes having a good understanding of banks’ demand for liquidity also called “reserves” at the central bank. This work aims to offer a modeling methodology for estimating the demand for reserves that itself is influenced by various macro and market structure variables. The model can help central banks to identify ”stable points” on the demand for reserves, which correspond to the levels of reserves for which the short-term interest rate volatility is minimal. Both parametric and non-parametric approaches are provided, with a particular focus on capturing the modeling uncertainty and, therefore, facilitating scenario analysis. A method is proposed to test the forecasting performances of different approaches and exogenous regressors combination, finding that simpler parametric expressions provide on balance better performances. Adding variables to both parametric and non-parametric provides better explanations and predictions. The proposed methodology is evaluated using data from the Euro system and the US Federal Reserve System.

Unconventional Fiscal Policy in Times of High Inflation
Description: The surge in energy prices in 2022 has been a defining factor behind the increase in euro area inflation. We assess the impact of “unconventional fiscal policy,” defined as the set of fiscal measures, possibly expansionary, motivated by a desire to mute the effects of the increase in energy prices and to lower inflation. Overall, we find that these unconventional measures reduced euro area inflation by 1 to 2 percentage points in 2022 and may avoid an undershoot later on. When nonlinearities in the Phillips curve are taken into account, the net effect is to reduce inflation by about 0.5 percentage points in 2021-24, and keep it nearer to its target. About one-third to one-half of the reduction in 2022 reflects the direct effects of the measures on headline inflation, with much of the remainder reflecting the lower pass-through to core inflation. The fiscal measures were deficit-financed but had limited effects on raising inflation by stimulating demand and instead modestly helped to stabilize longer-term inflation expectations. Looking ahead, the prospective decline in inflation in the euro area is partly due to fortunate circumstances, with energy prices falling from their 2022 peaks and their pass-through effects fading, and with less economic overheating than in economies such as the United States. Implementing similar measures in the face of a more persistent increase in energy prices, or in a more overheated economy, would have caused a more persistent rise in core inflation.

An Extended Quarterly Projection Model for the Central Bank of Jordan
Description: The Central Bank of Jordan (CBJ) has developed a Forecasting and Policy Analysis System (FPAS) to serve as a reliable analytical framework for macroeconomic analysis, forecasting and decision-making under a pegged exchange rate regime. At the heart of the FPAS is the CBJ’s extended Jordan Analysis Model (JAM2.0). The model captures the monetary transmission mechanism and provides a consistent monetary policy framework that uses the exchange rate as an effective nominal anchor. This paper outlines the structure and properties of JAM2.0 and emphasizes the enhanced interplay and tradeoffs among monetary, fiscal, and foreign exchange management policies. Simulation and forecasting exercises demonstrate JAM2.0’s ability to match key stylized facts of the Jordanian economy, produce accurate forecasts of important macroeconomic variables, and explain the critical relationships among policies.

Macroprudential Policies and Capital Controls Over Financial Cycles
Description: In this paper we assess the effectiveness of macroprudential policies and capital controls in supporting financial stability. We construct a large and granular dataset on prudential and capital flow management measures covering 53 countries during 1996-2016. Conditional on a credit boom, we study the impact of these policy measures on the probability of the credit boom ending in a bust. Our analysis suggests that macroprudential tools are effective from this perspective. If credit booms are accompanied by capital flow surges, in addition to macroprudential tools, capital controls on money market instruments including cross-border interbank lending tend to contribute to reducing the likelihood of a credit bust.

Unveiling the Hidden Impact of Urban Land Rents on Total Factor Productivity
Description: This paper addresses the puzzling decline of Total Factor Productivity (TFP) levels in rapidly growing economies, such as Singapore, despite advancements in technology and high GDP per capita growth. The paper proposes that TFP growth is not negative; instead, standard growth decompositions have underestimated TFP growth by overestimating the contribution of capital, failing to account for the substantial part of capital income directed to urban land rents. This leads to an overestimation of changes in capital stock's contribution to growth and thereby an underestimation of TFP growth. A revised decomposition suggests that TFP growth in economies with high land rents and rapid capital stock growth, such as Singapore, has been considerably underestimated: TFP levels have not declined but increased rapidly.
