Fiscal rules and discretion under persistent shocks

This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time-inconsistent preferences with a present-bias towards public spending. The government chooses a fiscal rule to trade off its desire to commit to not overspend against its desire to have flexibility to react to privately observed shocks to the value of spending. We analyze the optimal fiscal rule when the shocks are persistent. Unlike under i.i.d: shocks, we show that the ex-ante optimal rule is not sequentially optimal, as it provides dynamic incentives. The ex-ante optimal rule exhibits history dependence, with high shocks leading to an erosion of future fiscal discipline compared to low shocks, which lead to the reinstatement of discipline. The implied policy distortions oscillate over time given a sequence of high shocks, and can force the government to accumulate maximal debt and become immiserated in the long run

Fiscal shocks and real exchange rate dynamics: Some evidence for Latin America

This paper analyses the effects of fiscal shocks using a two-country macroeconomic model for output, labour input, government spending and relative prices which provides the orthogonality restrictions for obtaining the structural shocks. Dynamic simulation techniques are then applied, in particular to shed light on the possible effects of fiscal imbalances on the real exchange rate in the case of six Latin American countries. Using quarterly data over the period 1980-2006, we find that in a majority of cases fiscal shocks are the main driving force of real exchange rate fluctuations

Macroeconomic Shocks and the Business Cycle: Evidence from a Structural Factor Model

We use a dynamic factor model to provide a semi-structural representation for 101 quarterly US macroeconomic series. We find that (i) the US economy is well described by a number of structural shocks between two and six. Focusing on the four-shock specification, we identify, using sign re- strictions, two non-policy shocks, demand and supply, and two policy shocks, monetary and fiscal. We obtain the following results. (ii) Both supply and demand shocks are important sources of fluc- tuations; supply prevails for GDP, while demand prevails for employment and inflation. (ii) Policy matters, Both monetary and fiscal policy shocks have sizeable effects on output and prices, with little evidence of crowding out; both monetary and fiscal authorities implement important system- atic countercyclical policies reacting to demand shocks. (iii) Negative demand shocks have a large long-run positive effect on productivity, consistently with the Schumpeterian "cleansing" view of recessions.structural factor model, sign restrictions, monetary policy, fiscal policy, demand, supply

Fiscal policy shocks in the euro area and the US: an empirical assessment

We analyse the impact of fiscal policy shocks in the euro area as a whole, using a newly available quarterly dataset of fiscal variables for the period 1981-2007. To allow for comparability with previous results on euro area countries and the US, we use a standard structural VAR framework, and study the impact of aggregated and disaggregated government spending and net taxes shocks. In addition, to frame euro area results, we apply the same methodology for the same sample period to US data. We also explore the sensitivity of the provided results to the inclusion of variables aiming at measuring “financial stress” (increases in risk) and “fiscal stress” (sustainability concerns). Analysing US and euro area data with a common methodology provides some interesting insights on the interpretation of fiscal policy shocks.

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 deficits and output and construct two estimates for structural price differentials dynamics which optimally weight the information contained in the data for all units. Fiscal shocks explain between 14 and 23 percent of the variability of price differentials both in the US and in the EU. On average, expansionary fiscal disturbances produce positive price differential responses while distortionary balance budget shocks produce negative price differential responses. In a number of units, price differential responses to expansionary fiscal shocks are negative. Spillovers and labor supply effects partially explain this pattern while geographical, political, and economic indicators do not.Price differentials, Fiscal policy, Monetary unions, Bayesian methods

What Has Financed Government Debt?

Dynamic rational expectations models imply that the real value of debt in the hands of the public must be equal to the expected present-value of surpluses. We impose this equilibrium condition on an identified VAR and characterize the way in which the present-value support of debt varies across various types of fiscal policy shocks and between fiscal and non-fiscal shocks. The role of expected primary surpluses in supporting innovations to debt depends on the nature of the shock. For some fiscal policy shocks, debt is supported almost entirely by changes in the present-value of surpluses, however, in the case of other fiscal policy shocks, surpluses fail to adjust and instead leave a large role for expected changes in discount rates. Horizons over which debt innovations are financed are long – on the order of fifty years – while present-values calculated up to any finite horizon up to then fluctuate wildly, particularly following government spending and transfer shocks.

Monetary and Fiscal Policy Efficiency and Coordination in an Open-Economy General Equilibrium Model with Three Production Sectors.

The paper analyzes monetary and fiscal policy efficiency and coordination in a stochastic new open economy macroeconomics (NOEM) model with three production sectors. Some or all of these sectors can be affected by unanticipated productivity shocks which can trigger monetary and fiscal policy reactions. The uncertainty over the shocks can be symmetric or asymmetric across the two countries. The paper first aims to assess the capacity of fiscal and monetary policy to reduce or eliminate the negative effects of unanticipated productivity shocks. Second, it evaluates the possible gains from international monetary cooperation as well as the impact of active fiscal policy on monetary policy efficiency. The results show that monetary and fiscal policies are efficient tools of stabilization and under several conditions they can replicate the flexible-price equilibrium. However, their efficiency is not necessarily increased when both monetary and fiscal policies react to shocks at the national level. The existence of bilateral gains from monetary cooperation depends on the degree of asymmetry concerning the uncertainty over the shocks. In case of high asymmetry, monetary cooperation can be counter-productive either for the home or for the foreign country.Stabilization, international policy cooperation, monetary policy, fiscal policy.

What are the Effects of Fiscal Policy Shocks?

We propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions. Unlike most of the previous literature this approach does not require that the contemporaneous reaction of some variables to fiscal policy shocks be set to zero or need additional information, such as the timing of wars, in order to identify fiscal policy shocks. The paper's method is a purely vector autoregressive approach which can be universally applied. The approach also has the advantages that it is able to model the effects of announcements of future changes in fiscal policy and that it is able to distinguish between the changes in fiscal variables caused by fiscal policy shocks and those caused by business cycle and monetary policy shocks. We apply the method to US quarterly data from 1955-2000 and obtain interesting results. Our key finding is that the best fiscal policy to stimulate the economy is a deficit-financed tax cut and that the long term costs of fiscal expansion through government spending are probably greater than the short term gains.Fiscal Policy, Vector Autoregression, Bayesian Econometrics, Agnostic identification

Debt and the Effects of Fiscal Policy

A shift in taxes or in government spending (a "fiscal shock") at some point in time puts a constraint on the path of taxes and spending in the future, since the government intertemporal budget constraint will eventually have to be met. This simple fact is surprisingly overlooked in analyses of the effects of fiscal policy based on Vector AutoRegressive models. We study the effects of fiscal shocks keeping track of the debt dynamics that arises following a fiscal shock, and allowing for the possibility that taxes, spending and interest rates might respond to the level of the debt, as it evolves over time. We show that omitting a debt feedback can result in incorrect estimates of the dynamic effects of fiscal shocks. In particular, the absence of an effect of fiscal shocks on long-term interest rates -- a frequent finding in studies that omit a debt feedback -- can be explained by their mis-specification. Using data for the U.S. economy and two alternative identification assumptions we reconsider the effects of fiscal policy shocks correcting for these shortcomings.
