Risk Aversion, Wealth and Background Risk

We use household survey data to construct a direct measure of absolute risk aversion based on the maximum price a consumer is willing to pay to buy a risky security. We relate this measure to consumers' endowment and attributes and to measures of background risk and liquidity constraints. We find that risk aversion is a decreasing function of endowment - thus rejecting CARA preferences - but the elasticity to consumption is far below the unitary value predicted by the CRRA utility. We also find that households' attributes are of little help in predicting their degree of risk aversion, which is characterized by massive unexplained heterogeneity. However, the consumers' environment affects risk aversion. Individuals who are more likely to face income uncertainty or to become liquidity constrained exhibit a higher degree of absolute risk aversion, consistent with recent theories of attitudes towards risk in the presence of uninsurable risks.heterogeneous preferences, risk tolerance, background risk, liquidity constraints

THE ROLE OF RISK AVERSION IN PREDICTING INDIVIDUAL BEHAVIOR

We use household survey data to construct a direct measure of absolute risk aversion based on the maximum price a consumer is willing to pay to buy a risky asset. We relate this measure to a set of consumersÂ’ decisions that in theory should vary with attitude towards risk. We find that elicited risk aversion has considerable predictive power for a number of key household decisions such as choice of occupation, portfolio selection, moving decisions and exposure to chronic diseases in ways consistent with theory. We also use this indicator to address the importance of self-selection when relating indicators of risk to individual saving decisions.risk aversion, heterogeneous preferences, choice under risk, entrepreneurship, self selection.

Do capital gains affect consumption? Estimates of wealth effects from Italian householdsÂ’ behavior

We use detailed data on housing prices in Italy available for a large number of years and with a fine geographical breakdown to compute capital gains and losses on the most widespread asset among consumers, housing, and inquire whether changes in housing values affect consumption. We find that consumer expenditures do react to capital gains, with a marginal propensity to consume out of real value changes of housing wealth of about 0.02. Reactions are different across types of consumers: while homeowners increase consumption when house prices increase, with a marginal propensity of about 0.035, the rentersÂ’ response to the higher house cost tends to be that of increased savings. For the owners of listed stocks the response to capital gains is difficult to estimate with statistical precision, even if, for the limited sample of owners of these assets, its negative sign may be indicative of prevailing substitution over income effects.wealth effects, consumption, housing, stock ownership

Bank Risk and Monetary Policy

We find evidence of a bank lending channel for the euro area operating via bank risk. Financial innovation and the new ways to transfer credit risk have tended to diminish the informational content of standard bank balance-sheet indicators. We show that bank risk conditions, as perceived by financial market investors, need to be considered, together with the other indicators (i.e. size, liquidity and capitalization), traditionally used in the bank lending channel literature to assess a bank’s ability and willingness to supply new loans. Using a large sample of European banks, we find that banks characterized by lower expected default frequency are able to offer a larger amount of credit and to better insulate their loan supply from monetary policy changes
