This paper explores time variation in the dynamic effects of technology shocks on U.S. output, prices, interest rates as well as real and nominal wages. The results indicate considerable time variation in U.S. wage dynamics that can be linked to the monetary policy regime. Before and after the 'Great Inflation', nominal wages moved in the same direction as the (required) adjustment of real wages, and in the opposite direction of the price response. During the 'Great Inflation', technology shocks in contrast triggered wage-price spirals, moving nominal wages and prices in the same direction at longer horizons, thus counteracting the required adjustment of real wages, amplifying the ultimate repercussions on prices and hence increasing inflation volatility. Using a standard DSGE model, we show that these stylized facts, in particular the estimated magnitudes, can only be explained by assuming a high degree of wage indexation in conjunction with a weak reaction of monetary policy to inflation during the 'Great Inflation', and low indexation together with aggressive inflation stabilization of monetary policy before and after this period. This means that the monetary policy regime is not only captured by the parameters of the monetary policy rule, but importantly also by the degree of wage indexation and resultant second round effects in the labor market. Accordingly, the degree of wage indexation is not structural in the sense of Lucas (1976).

The paper shows that monetary policy shocks exert a substantial effect on the size and composition of capital flows and the trade balance for the United States, with a 100 basis point easing raising net capital inflows and lowering the trade balance by 1% of GDP, and explaining about 20-25% of their time variation. Monetary policy easing causes positive returns to both equities and bonds. Yet such a monetary policy easing shock also induces a shift in portfolio composition out of equities and into bonds, implying a negative conditional correlation between flows in equities and bonds. Moreover, such shocks induce a negative conditional correlation between equity flows and equity returns, but a positive conditional correlation between bond flows and bond returns. The findings thus provide evidence for the presence of a portfolio rebalancing motive behind investment decisions in equities, but the dominance of what is akin to a return chasing motive for bonds, conditional on monetary policy shocks. The results also shed light on the puzzle of the strongly time-varying equity-bond return correlations found in the literature.

In this paper, we examine the macroeconomic effects of alternative fiscal consolidation policies in the New Area-Wide Model (NAWM), a two-country open-economy model of the euro area developed at the European Central Bank (cf. Coenen et al., 2007). We model fiscal consolidation as a permanent reduction in the targeted government debt-to-output ratio and analyse both expenditure and revenue-based policies that are implemented by means of simple fiscal feedback rules. We find that fiscal consolidation has positive long-run effects on key macroeconomic aggregates such as output and consumption, notably when the resulting improvement in the budgetary position is used to lower distortionary taxes. At the same time, fiscal consolidation gives rise to noticeable short-run adjustment costs in contrast to what the literature on expansionary fiscal consolidations suggests. Moreover, depending on the fiscal instrument used, fiscal consolidation may have pronounced distributional effects.

There may be a connection between suicidal tendencies, electrodermal activity (EDA), disorders of impulse control, and neurobiochemistry (in the sense of a "psychobiology of suicidal tendencies"). The EDA values obtained during a psychobiological habituation experiment involving 11 female patients with personality disorders (PA; ICD-10) and histories of suicide attempts were compared with those of age-paralleled nonsuicidal depressive patients and depressive patients with histories of suicide attempts. They were also compared with EDA values in female schizophrenics with and without histories of suicide attempts. The PA group showed significant differences in all EDA values compared with nonsuicidal depressives, but no significant differences compared with other groups.
