We review different empirical approaches that researchers have taken to estimate how consumption responds to income changes. We critically evaluate the empirical evidence on the sensitivity of consumption to predicted income changes, distinguishing between the traditional excess sensitivity...

We estimate the effect of estate taxation on bequests exploiting a sequence of Italian reforms that culminated with the reduction of estate taxes in 1999 and their abolishment in 2001. To perform our exercise, we use the 1993-2006 Survey of Household Income and Wealth, which has data on real...

We estimate the portfolio effect of changes in social security wealth exploiting a decade of Italian pension reforms as a source of exogenous variation. The Italian Survey of Household Income and Wealth records detailed portfolio data and elicits expectations of retirement outcomes, thus...

Rational investors perceive correctly the value of financial information. Investment in information is therefore rewarded with a higher Sharpe ratio. Overconfident investors overstate the quality of their own information, and thus attain a lower Sharpe ratio. We contrast the implications of the...

The cost of enforcing contracts is a key determinant of market performance. We document this point with reference to the credit market in a model of opportunistic debtors and inefficient courts. According to the model, improvements in judicial efficiency should reduce credit rationing and...

We test for the presence of precautionary saving using a self-reported measure of earnings uncertainty drawn from the 1989 Italian Survey of Household Income and Wealth. The effect of uncertainty on saving and wealth accumulations is consistent with the theory of precautionary saving and with...

Existing estimates of the age-wealth profile use panel or cross-sectional data. Panels with wealth data are rare, and plagued by measurement errors and sample attrition. Cross-sectional data require strong identifying assumptions. This paper represents the first attempt to use repeated...

Theory suggests that people facing higher uninsurable background risk buy more insurance against other risks that are insurable. This proposition is supported by Italian cross-sectional data. It is shown that the probability of purchasing casualty insurance increases with earnings uncertainty....

Economic theory suggests that uninsurable income risk, health risk and the expectation of future borrowing constraints can reduce the share of risky assets in a household's portfolio. In fact, if its utility function exhibits decreasing absolute risk aversion and decreasing prudence, a household...

The extent to which consumers are aware of available financial assets depends on the incentives of asset suppliers to spread information about the instruments they issue. We propose a theoretical framework in which the amount of information disseminated and the probability of individuals...
