We develop a framework for optimal taxation when agents can earn their income both in traditional activities, where private and social products coincide, and in rent-seeking activities, where private returns exceed social returns either because they involve the capture of pre-existing rents or...

A fall in house prices due to a change in fundamental value redistributes wealth from those long housing (for whom the fundamental value of the house they own exceeds the present discounted value of their planned future consumption of housing services) to those short housing. In a representative...

We study a model in which financial sophistication improves portfolio returns and therefore the incentive to substitute consumption intertemporally. The model delivers a Euler equation in which consumption growth is positively correlated with financial sophistication. We test the model's...

We merge administrative information from a large German discount brokerage firm with regional data to examine if financial advisors improve portfolio performance. Our data track accounts of 32,751 randomly selected individual customers over 66 months and allow direct comparison of performance...

We study the relation between cognitive ability and the decision to invest in stocks using the recent Survey of Health, Ageing and Retirement in Europe (SHARE). The survey has detailed data on wealth and portfolio composition of individuals aged 50+ in 11 European countries and three indicators...

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...

An independent currency and a flexible exchange rate generally helps a country in adjusting to macroeconomic shocks. But recently in many countries, interest rates have been pushed down close to the lower bound, limiting the ability of policy-makers to accommodate shocks, even in countries with...

Using a variance decomposition of shocks to GDP, we quantify the role of international factor income, international transfers, and saving in achieving risk sharing during the recent European crisis. We focus on the sub-periods 1990--2007, 2008--2009, and 2010 and consider separately the European...

Periods of high indebtedness have historically been associated with a rising incidence of default or restructuring of public and private debts. Sometimes the debt restructuring is more subtle and takes the form of 'financial repression'. Consistent negative real interest rates are equivalent to...

This paper aims to provide a rigorous analysis of Milton Friedman’s famous parable of the ‘helicopter’ drop of money. A helicopter drop of money is a permanent/irreversible increase in the nominal stock of fiat base money with a zero nominal interest rate, which respects the intertemporal...
