Author's abstract. In nonlinear state-space models, sequential learning about the hidden state can proceed by particle filtering when the density of the observation conditional on the state is available analytically (e.g. Gordon et al. 1993). This condition need not hold in complex environments,...

This paper investigates the efficiency of household investment decisions in a unique dataset containing the disaggregated wealth and income of the entire population of Sweeden.

This paper investigates the determinants of value and growth investing in a large administrative panel of Swedish residents over the 1999-2007 period. The authors document strong relationships between a household's portfolio tilt and the household's financial and demographic characteristics....

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. The authors' approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria...

We introduce a tractable class of non-affine price processes with multifrequency stochastic volatility and jumps. The specifi cations require few fixed parameters and deliver fast option pricing. One key ingredient is a tight link between jumps and volatility regimes, as asset pricing theory...
