Survey respondents strongly disagree about return risks and, increasingly, macroeconomic uncertainty. This may have contributed to higher asset prices through increased use of collateralisation, which allows risk-neutral investors to realise perceived gains from trade. Investors with lower risk...

The fall in US macroeconomic volatility from the mid-1980s coincided with a strong rise in asset prices. Recently, this rise, and the crash that followed, have been attributed to overconfidence in a benign macroeconomic environment of low volatility. This paper introduces learning about the...

This paper shows how financial innovation in combination with the fall of macroeconomic risk can explain the strong growth of the primary and secondary credit markets in the U.S. economy. We document empirically the fall in macroeconomic risk, the expansion of the prime and secondary credit...

This paper documents how poorer and less educated US households hold a smaller fraction of foreign assets in their financial portfolio. This average home bias of the poor is partly due to a lower probability of participating in foreign asset markets, often attributed to fixed costs of market...

When default leads to exclusion from financial markets, the implied loss of consumption smoothing opportunities is more costly when income volatility is high. A rise in income risk thus makes default less attractive, allowing creditors to relax borrowing limits. I show how, in an open economy,...

In this paper, we study consumption risk sharing when individual income shocks are persistent and not publicly observable, and individuals can default on contracts at the price of financial autarky. We find that, in contrast to a model where the only friction is limited enforcement, our model...

When the risk of default constrains financial contracts, public insurance policies can significantly affect private risk-sharing. This is because by changing income expectations and volatility, redistribution changes the attractiveness of default and thus endogenous borrowing constraints....

This paper shows how two standard models of consumption risk-sharing - self-insurance through borrowing and saving and limited commitment to insurance contracts - replicate similarly well the standard, second-moment measures of insurance observed in US micro-data. A non-parametric analysis,...
