Nel corso dell'ultimo decennio le abitudini del risparmiatore italiano sono state oggetto di radicali mutamenti imputabili ad una serie di fattori di carattere sia strutturale che congiunturale. Alla crescente alfabetizzazione finanziaria e alle rilevanti prospettive offerte dalle tecnologie...

This paper is concerned with accounting for the saving and capital formation taking place in different sectors of the U.S. economy. In brief, where does saving arise and where is it used? Do some sectors save more than they spend for capital formation and thus are net lenders? Do other sectors...

A central implication of life-cycle models is that agents smooth consumption. We review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime. We find that life-cycle models--particular those which incorporate realistic features of markets and...

Most advanced economies have experienced a striking decline in the volatility of aggregate economic activity since the early 1980s. Volatility reductions are evident for output and employment at the aggregate level and across most industrial sectors and expenditure categories. Inflation and...

This paper explores a monetary-policy model with habit formation for consumers, in which consumers' utility depends in part on current consumption relative to past consumption. The empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with...

This paper studies the interaction between time preference heterogeneity and precautionary saving in generating both persistent current account imbalance and a stationary equilibrium distribution of wealth across countries. We use numerical techniques to present two sets of results. First, when...

German reunification was a large, unexpected shock for East Germans. Exploiting German reunification as a natural experiment, I analyze the validity of the life-cycle consumption model. I derive three stylized features concerning the saving behavior of East versus West Germans after...
