A comparison of national saving rates in the UK, US and Italy

We develop the approach of Gokhale, Kotlikoff and Sabelhaus [1996. Understanding the postwar decline in US saving: A cohort analysis. Brookings Papers on Economic Activity 0, 315-390], based on the life-cycle model of savings, to decompose the differences in the national saving rates between the UK, US and Italy. Our work suggests that the US saving rate is lower principally because Americans on average retire later. In contrast, the Italian saving rate is higher predominantly because Italians are credit constrained, particularly when young. We also found that demography and the different tax and benefit systems are able to explain little of the cross-sectional differences in saving rates. The study accounts for the possible importance of inter-generational private transfers in determining saving rates.     

The Interactions between Fiscal Policy and Monetary Policy

This paper studies the interactions of fiscal policy and monetarypolicy when they stabilize a single economy against shocks ina dynamic setting. If both policy-makers are benevolent, then,in our model, the best outcome is achieved when monetary policydoes nearly all of the stabilization. If the monetary authoritiesare benevolent, but the fiscal authority discounts the future,or aims for an excessive level of output, then a Nash equilibriumwill result in large welfare losses: after an inflation shockthere will be excessively tight monetary policy, excessive fiscalexpansion, and a rapid accumulation of public debt. However,if, in these circumstances, there is a regime of fiscal leadership,then the outcome will be very nearly as good as when both policy-makersare benevolent.
