Financial innovation in recent decades has expanded portfolio choice. We investigate how greater choice affects investors' savings and asset returns. We establish a choice channel by which greater portfolio choice increases investors' savings --- by enabling them to earn the aggregate risk...

We study how investors respond to inflation combining a customized survey experiment with trading data at a time of historically high inflation. Investors' beliefs about the stock return-inflation relation are very heterogeneous in the cross section and on average too optimistic. Moreover, many...

By the time the Colombian government closed DMG and DRFE, two Ponzi schemes that were operating in Colombia until 2008, over half a million customers had deposited funds corresponding to 1.2% of Colombia's annual GDP. We show that the individuals who invested in DMG and DRFE obtained close to...

Home owners are about twice as likely as renters to participate in the stock market, both in the USA and Sweden. This paper sets up a life-cycle portfolio choice model which generates this pattern of limited stock market participation. Calibrated to Swedish data, the model generates the stock...

The stock market participation rate among homeowners is twice as high as among renters. This paper builds a life-cycle portfolio choice model with endogenous housing tenure choice. A stylized form of preference heterogeneity generates a substantial difference in participation rates. A majority...

Deriving an optimal asset allocation hinges crucially on the quality of inputs used in the optimization. If the vector of expected returns and the covariance matrix are known with certainty, mean-variance optimization produces optimal portfolios. If, however, these parameters are estimated with...
