This paper investigates the determinants of financial risk-taking in a panel containing the asset holdings of Swedish twins. We measure the impact of a broad set of demographic, financial, and portfolio characteristics, and use yearly twin pair fixed effects to control for genes and shared...

This paper constructs an index of financial sophistication that, in comprehensive data on Swedish households, best explains a set of three investment mistakes: underdiversification, risky share inertia, and the tendency to sell winning stocks and hold losing stocks (the disposition effect). The...

This paper investigates the efficiency of household investment decisions in a unique dataset containing the disaggregated wealth and income of the entire population of Sweden. The analysis focuses on two main sources of inefficiency in the financial portfolio: underdiversification of risky...

We model the opacity of over-the-counter (OTC) markets in a setup where agents share risks, but have incentives to default and their financial positions are not mutually observable. We show that this setup results in excess "leverage" in that parties take on short OTC positions that lead to...

This paper investigates the dynamics of individual portfolios in a unique dataset containing the disaggregated wealth of all households in Sweden. Between 1999 and 2002, we observe little aggregate rebalancing in the financial portfolio of participants. These patterns conceal strong...

We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country's access to external borrowing. In turn, access to borrowing...

We analyze the determinants and the long-run consequences of government interventions in the eurozone banking sector during the 2008/09 financial crisis. Using a novel and comprehensive dataset, we document that fiscally constrained governments "kicked the can down the road" by providing banks...

We show that cheap credit to impaired firms has a disinflationary effect. By helping distressed firms to stay afloat, "zombie credit" can create excess production capacity, and in turn, put downward pressure on markups and prices. We test this mechanism exploiting granular inflation and...

We show that Eurozone bank risks during 2007-2012 can be understood as a "carry trade" behavior. Bank equity returns load positively on peripheral (Greece, Ireland, Portugal, Spain and Italy, or GIPSI) bond returns and negatively on German government bond returns, a position that generated...

Macroprudential stress tests have been employed by regulators in the United States and Europe to assess and address the solvency condition of financial firms in adverse macroeconomic scenarios. We provide a test of these stress tests by comparing their risk assessments and outcomes to those from...
