We build a factor-augmented interacted panel vector-autoregressive model of the Euro Area (EA) and estimate it with Bayesian methods to compute government spending multipliers. The multipliers are contingent on the overall monetary policy stance, captured by a shadow monetary policy rate. In the short run (one year), whether the fiscal shock occurs when the economy is at the effective lower bound (ELB) or in normal times does not seem to matter for the size of the multiplier. However, as the time horizon increases, multipliers diverge across the two regimes. In the medium run (three years), the average multiplier is about 1 in normal times and between 1.6 and 2.8 at the ELB, depending on the specification. The difference between the two multipliers is distributed largely away from zero. More generally, the multiplier is inversely correlated with the level of the shadow monetary policy rate. In addition, we verify that EA data lend support to the view that the multiplier is larger in periods of economic slack, and we show that the shadow rate and the state of the business cycle are autonomously correlated with its size. The econometric approach deals with several technical problems highlighted in the empirical macroeconomic literature, including the issues of fiscal foresight and limited information.

This paper provides estimates of output multipliers for spending in clean energy and biodiversity conservation, as well as for spending on non-ecofriendly energy and land use activities. Using a new international dataset, we find that every dollar spent on key carbon-neutral or carbon-sink activities can generate more than a dollar’s worth of economic activity. Although not all green and non-ecofriendly expenditures in the dataset are strictly comparable due to data limitations, estimated multipliers associated with spending on renewable and fossil fuel energy investment are comparable, and the former (1.1-1.5) are larger than the latter (0.5-0.6) with over 90 percent probability. These findings survive several robustness checks and lend support to bottom-up analyses arguing that stabilizing climate and reversing biodiversity loss are not at odds with continuing economic advances.

Sovereign risk premia in several euro area countries have risen markedly since 2008, driving up credit spreads in the private sector as well. We propose a New Keynesian model of a two-region monetary union that accounts for this “sovereign risk channel.” The model is calibrated to the euro area as of mid-2012. We show that a combination of sovereign risk in one region and strongly procyclical fiscal policy at the aggregate level exacerbates the risk of belief-driven deflationary downturns. The model provides an argument in favor of coordinated, asymmetric fiscal stances as a way to prevent selffulfilling debt crises.

This paper employs two established macroeconomic models to show that fiscal policy in the euro area can help monetary policy in reducing inflation. Specifically, a fiscal consolidation of 1 percent of GDP for two years and 0.5 percent in the third year across the euro area would ease the policy interest rate by 30-50 basis points relative to the baseline scenario, while lowering inflation. It would also put the public debt-to-GDP ratio on a downward path, with the output costs reversing after the second year. Additionally, a stronger fiscal contribution to the policy mix could mitigate financial fragmentation risks. In the current context of elevated inflation in all euro area economies, the findings suggest two key takeaways: first, synchronized fiscal and monetary policies offer gains even when monetary policy is unconstrained and, second, sharing the burden of lowering inflation through fiscal consolidation among euro area members is beneficial for union-wide inflation reduction, improving debt sustainability and inducing a lower policy rate path.

We estimate government spending multipliers in demand- and supply-driven recessions for the Euro Area. Multipliers in a moderately demand-driven recession are 2-3 times larger than in a moderately supply-driven recession, with the difference between multipliers being non-zero with very high probability. More generally, multipliers are inversely correlated with the deviation of inflation from its trend, implying that the more demand-driven a recession, the higher the multiplier. Median multipliers range from -0.5 in supply-driven recessions to about 2 in demand-driven recessions. The econometric approach leverages a factor-augmented interacted vector-autoregression model purified of expectations (FAIPVAR-X). The model captures the time-varying state of the business-cycle including strongly and moderately demand- and supply-driven recessions, by taking the whole distribution of inflation deviations from trend into account.

This paper reviews empirical and theoretical work on the links between banks and their governments (the bank-sovereign nexus). How significant is this nexus? What do we know about it? To what extent is it a source of concern? What is the role of policy intervention? The paper concludes with a review of recent policy proposals.
