A wide body of empirical evidence finds that approximately 25 percent of fiscal stimulus payments (e.g., tax rebates) are spent on nondurable household consumption in the quarter that they are received. To interpret this fact, we develop a structural economic model where households can hold two assets: a low-return liquid asset (e.g., cash, checking account) and a high-return illiquid asset that carries a transaction cost (e.g., housing, retirement account). The optimal life-cycle pattern of portfolio choice implies that many households in the model are \"wealthy hand-to-mouth\": they hold little or no liquid wealth despite owning sizable quantities of illiquid assets. Therefore, they display large propensities to consume out of additional transitory income, and small propensities to consume out of news about future income. We document the existence of such households in data from the Survey of Consumer Finances. A version of the model parameterized to the 2001 tax rebate episode yields consumption responses to fiscal stimulus payments that are in line with the evidence, and an order of magnitude larger than in the standard \"one-asset\" framework. The model's nonlinearities with respect to the rebate size and the prevailing aggregate economic conditions have implications for policy design.

Only a few empirical studies have analyzed the relationship between fiscal multipliers and the underlying state of the economy. This paper investigates this link on a country-by-country basis for the G7 economies (excluding Italy). Our results show that fiscal multipliers differ across countries, calling for a tailored use of fiscal policy. Moreover, the position in the business cycle affects the impact of fiscal policy on output: on average, government spending, and revenue multipliers tend to be larger in downturns than in expansions. This asymmetry has implications for the choice between an upfront fiscal adjustment versus a more gradual approach.

Abstract The COVID-19 crisis is likely to have dramatic consequences for progress on climate change. Imminent fiscal recovery packages could entrench or partly displace the current fossil-fuel-intensive economic system. Here, we survey 231 central bank officials, finance ministry officials, and other economic experts from G20 countries on the relative performance of 25 major fiscal recovery archetypes across four dimensions: speed of implementation, economic multiplier, climate impact potential, and overall desirability. We identify five policies with high potential on both economic multiplier and climate impact metrics: clean physical infrastructure, building efficiency retrofits, investment in education and training, natural capital investment, and clean R&D. In lower- and middle-income countries (LMICs) rural support spending is of particular value while clean R&D is less important. These recommendations are contextualized through analysis of the short-run impacts of COVID-19 on greenhouse gas curtailment and plausible medium-run shifts in the habits and behaviours of humans and institutions.

We identify fiscal policy shocks in the EU new member states using four different methods. We use panel data techniques to estimate the output response to these shocks. We find that investment and export growth increase after fiscal consolidation and decelerate after fiscal stimulus when the shocks are expenditure-based. In contrast, private consumption does not respond to fiscal policy shocks. Expenditure-based fiscal consolidations reduce wages, supporting the view that fiscal consolidation of such composition enhances the competitiveness and profitability of domestic enterprises. In contrast, we do not find evidence of fiscal shocks affecting households' confidence.

We investigate housing market responses to transaction taxes using administrative data on all property transactions in the U.K. from 2004 to 2012 combined with quasi-experimental variation from tax notches and tax stimulus. We present two main findings. First, transaction taxes are highly distortionary across a range of margins, causing large distortions to the price, volume, and timing of property transactions. Secondly, temporary transaction tax cuts are an enormously effective form of fiscal stimulus. A temporary elimination of a 1% transaction tax increased housing market activity by 20% in the short run (due to both timing and extensive responses) and less than half of the stimulus effect was reversed after the tax was reintroduced (due to re-timing). Because of the complementarities between moving house and consumer spending, these stimulus effects translate into extra spending per dollar of tax cut equal to about 1. We interpret our empirical findings in the context of a housing model with downpayment constraints in which leverage amplifies the effects of transaction taxes.

In 2009 and 2010, China undertook a fiscal stimulus program worth 4 trillion yuan, roughly equivalent to 11 percent of its annual GDP. This program was largely financed by off-balance-sheet companies—known as local financing vehicles—that both borrowed and spent on behalf of local governments. These companies have continued to grow since the stimulus program concluded at the end of 2010; their spending has accounted for roughly 10 percent of GDP each year, with an increasing share used for what are essentially commercial projects. And their spending has likely been responsible for an increase of 5 percentage points in the aggregate investment rate and for part of the decline of 7 to 8 percentage points in the current account surplus since 2008. We argue that local governments have used their new access to financial resources to facilitate favored businesses’ access to capital, which potentially worsens the overall efficiency of capital allocation. The long-run effect of off-balance- sheet spending by local governments may be a permanent decline in the growth rate of aggregate productivity and GDP.

We evaluate the impact of the 2009 Cash for Clunkers program on shortand medium-run auto purchases. Our empirical strategy exploits variation across U.S. cities in ex ante exposure to the program as measured by the number of \"clunkers\" in the city as of summer 2008. We find that the program induced the purchase of an additional 370,000 cars in July and August 2009. However, we find strong evidence of reversal; high clunker counties bought fewer autos in the 10 months after the program expired, which offset most of the initial purchases. We find no evidence of an effect on employment, house prices, or household default rates in cities with higher exposure to the program.

Strengthening fiscal frameworks, in particular fiscal rules, has emerged as a key response to the fiscal legacy of the crisis. This paper takes stock of fiscal rules in use around the world, compiles a dataset - covering national and supranational fiscal rules, in 81 countries from 1985 to end-March 2012 - and presents details about the rules' key design elements, particularly in support of enforcement. This information is summarized in a set of fiscal rules indices. Three key findings emerge: (i) many new fiscal rules have been adopted and existing ones strengthened in response to the crisis; (ii) the number of fiscal rules and the comprehensiveness of the design features in emerging economies has caught up to those in advanced economies; and (iii) the \"next-generation\" fiscal rules are increasingly complex as they combine the objectives of sustainability and with the need for flexibility in response to shocks, thereby creating new challenges for implementation, communication, and monitoring.

This paper studies the effects of fiscal policy response in 118 episodes of systemic banking crisis in advanced and emerging market countries during 1980-2008. It finds that timely countercyclical fiscal measures contribute to shortening the length of crisis episodes by stimulating aggregate demand. Fiscal expansions that rely mostly on measures to support government consumption are more effective in shortening the crisis duration than those based on public investment or income tax cuts. But these results do not hold for countries with limited fiscal space where fiscal expansions are prevented by funding constraints. The composition of countercyclical fiscal responses matters as well for output recovery after the crisis, with public investment yielding the strongest impact on growth. These results suggest a potential trade-off between short-run aggregate demand support and medium-term productivity growth objectives in fiscal stimulus packages adopted in distress times.
