Author's abstract. This paper investigates the determinants of financial risk-taking and documents new facts on the financial wealth elasticity of the risky share in a panel of swedish twins. <p>We consider a uniquely comprehensive set of demographic and financial characteristics, and use yearly...</p>

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,...

We investigate a neoclassical economy with heterogeneous agents, convex technologies and idiosyncratic production risk. Combined with precautionary savings, investment risk generates rich effects that do not arise in the presence of pure endowment risk. Under a finite horizon, multiple growth...

This paper proposes that the introduction of non-redundant assets can endogenously modify trader participation in financial markets, which can lead to a lower market premium and a higher interest rate. We demonstrate this mechanism in a tractable exchange economy with endogenous participation....

The Multifractal Model of Asset Returns ("MMAR," see Mandelbrot, Fisher, and Calvet, 1997) proposes a class of multifractal processes for the modelling of financial returns. In that paper, multifractal processes are defined by a scaling law for moments of the processes' increments over finite...

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 show in this paper how, in a model of assets exchange in complete competitive markets, heterogeneity of the agent’s sub jective probabilities generates aggregate expenditures for Arrow-Debreu securities that have the gross substitutability property, with the consequences that competitive...
