Price Differentials in Monetary Unions: The Role of Fiscal Shocks*

We study the effect of regional expenditure and revenue shocks on price differentials for 47 US states and 9 EU countries. We identify shocks using sign restrictions on the dynamics of expenditures, revenues, deficits and output and construct two estimates for structural price differentials dynamics, one for the average and one for each unit, which optimally weight information contained in the data for all units. On average, expansionary fiscal disturbances produce positive, while distortionary balance budget shocks produce negative price differential responses. The negative price differentials responses in some units is partially explained by spillovers and labour supply effects.

The Structural Dynamics of Output Growth and Inflation: Some International Evidence

We examine the dynamics of output growth and inflation in the US, Euro area and UK using a structural time varying coefficient VAR. There are important similarities in structural inflation dynamics across countries; output growth dynamics differ. Swings in the magnitude of inflation and output growth volatilities and persistences are accounted for by a combination of three structural shocks. Changes over time in the structure of the economy are limited and permanent variations largely absent. Changes in the volatilities of structural shocks matter.

Fiscal Policy, Pricing Frictions and Monetary Accommodation

We investigate the theoretical conditions for effectiveness of government consumption expenditure expansions using US, Euro area and UK data. Fiscal expansions taking place when monetary policy is accommodative lead to large output multipliers in normal times. The 2009-2010 packages need not produce significant output multipliers, may have moderate debt effects, and only generate temporary inflation. Expenditure expansions accompanied by deficit/debt consolidations schemes may lead to short run output gains but their success depends on how monetary policy and expectations behave. Trade openness and the cyclicality of the labor wedge explain cross-country differences in the magnitude of the multipliers.

New-keynesian or RBC transmission? The effects of fiscal shocks in labour markets

We study the mechanics of transmission of fiscal shocks to labor markets. We characterize a set of robust implications following government consumption, investment and employment shocks in a RBC and a New-Keynesian model and use part of them to identify shocks in the data. In line with the New-Keynesian story, shocks to government consumption and investment increase real wages and employment contemporaneously both in US aggregate and in US state data. The dynamics in response to employment shocks are mixed, but in many cases are inconsistent with the predictions of the RBC model.

Fiscal expansions, unemployment and labor force participation: theory and evidence

Structural VARs indicate that for many OECD countries labor force participation, employment, and the unemployment rate significantly increase following increases in government expenditures under a variety of specifications and identification schemes. Fiscal expansions also tend to increase real wages. Existing models have difficulties in generating such responses. We show that the empirical regularities can be reproduced with two additions into a standard New Keynesian model with matching frictions: (a) a labor force participation choice and (b) workers’ heterogeneity.

Fiscal consolidation with tax evasion and corruption

Cross-country evidence highlights the importance of tax evasion and corruption in determining the size of fiscal multipliers. We introduce these two features in a New Keynesian model and revisit the effects of fiscal consolidations. VAR evidence for Italy suggests that spending cuts reduce tax evasion, while tax hikes increase it. In the model, spending cuts induce a reallocation of production towards the formal sector, thus reducing tax evasion. Tax hikes increase the incentives to produce in the less productive shadow sector, implying higher output and unemployment losses. Corruption further amplifies these losses by requiring larger hikes in taxes to reduce debt. We use the model to assess the recent fiscal consolidation plans in Greece, Italy, Portugal and Spain. Our results corroborate the evidence of increasing levels of tax evasion during these consolidations and point to significant output and welfare losses, which could be reduced substantially by combating tax evasion and corruption.(This abstract was borrowed from another version of this item.)

Chronicle of a War Foretold: The Macroeconomic Effects of Anticipated Defense Spending Shocks

We identify US defense news shocks as shocks that best explain future movements in defense spending over a five-year horizon and are orthogonal to current defense spending. Our identified shocks are strongly correlated with the Ramey (2011) news shocks, but explain a larger share of macroeconomic fluctuations and have significant demand effects. Fiscal news induces significant and persistent increases in output, consumption, investment, hours and the interest rate. Standard DSGE models fail to produce such a pattern. We propose a sticky price model with distortionary taxation, variable capital utilization, capital adjustment costs and rule-of-thumb consumers that replicates the empirical findings.

A Monetary Model of Factor Utilisation

The propagation mechanism of monetary shocks in an otherwise standard sticky-price model is examined, modified to incorporate factor hoarding in the form of variable capital utilisation rates and labour effort. In contrast to previous studies, it is found that real effects of monetary shocks can be generated at relatively low degrees of nominal rigidity. Factor hoarding enriches the propagation mechanism by flattening the marginal cost responses to monetary shocks. The assumption of labour hoarding is crucial for generating persistence, while the assumption of variable capital utilisation allows the generation of realistic investment volatility, without having to introduce capital adjustment costs.

The transition from national currencies to the euro

Abstract We initiated a survey to examine whether the transition from national currencies to the Euro involved significant increases in transaction times. Based on our sample of 42 observations, we found that the pure transaction time for making change did actually increase, while queuing time increased only in small shops. This increase in transaction time represented a more significant welfare loss than most estimated studies of shoe-leather cost have previously found.

Gains from Coordination in a Multi-Sector Open Economy: Does it Pay to be Different?

Do countries gain by coordinating their monetary policies if they have different economic structures? We address this issue in the context of a new open-economy macro model with a traded and a non-traded sector and more importantly, with a across-country asymmetry in the size of the traded sector. We study optimal monetary policy under independent and cooperating central banks, based on analytical expressions for welfare objectives derived from quadratic approximations to individual preferences. In the presence of asymmetric structures, a new source of gains from coordination emerges due to a terms-of-trade externality. This externality affects unfavorably the country that is more exposed to trade and its effects tend to be overlooked when national central banks act independently. The welfare gains from coordination are sizable and increase with the degree of asymmetry across countries and the degree of openness, and decrease with the within-country correlation of sectoral shocks.
