Monetary Policy, Bank Bailouts and the Sovereign-Bank Risk Nexus in the Euro Area

The paper analyses the empirical relationship between bank risk and sovereign credit risk in the euro area. Using structural VAR with daily financial markets data for 2003-13, the analysis confirms two-way causality between shocks to sovereign risk and bank risk, with the former being overall more important in explaining bank risk, than vice versa. The paper focuses specifically on the impact of non-standard monetary policy measures by the European Central Bank and on the effects of bank bailout policies by national governments. Testing specific hypotheses formulated in the literature, we find that bank bailout policies have reduced solvency risk in the banking sector, but partly at the expense of raising the credit risk of sovereigns. By contrast, monetary policy was in most, but not all cases effective in lowering credit risk among both sovereigns and banks. Finally, we find spillover effects in particular from sovereigns in the euro area periphery to the core countries.

Personal income tax progressivity and output volatility: Evidence from OECD countries

This paper investigates empirically the effect of personal income tax progressivity on output volatility using macro data from a sample of OECD countries over the period 19822009. Our measure of progressivity is based on the difference between the marginal and the average personal income tax rate for the average production worker. We find supportive empirical evidence for the hypothesis that higher personal income tax progressivity leads to lower output volatility. This effect comes in addition to the stabilizing impact of government size and it is equally important in economic terms. All other factors constant, countries with more progressive personal income tax systems seem to benefit from stronger automatic stabilizers.

Unconventional Monetary Policy, Fiscal Side Effects and Euro Area (Im)balances

We study the macroeconomic effects of unconventional monetary policy in the euro area using structural vector autoregressions, identified with an external instrument. The instrument is the common unexpected variation in euro area sovereign spreads for different maturities on policy announcement days. We first show that expansionary monetary surprises are effective at lowering public and private interest rates and increasing economic activity, consumer prices, and inflation expectations. We also find, however, that the shocks lead to a rise in primary public expenditures, a divergence of consumer prices within the union, and a widening of internal trade balances.
