We construct a parsimonious model of a financial market where the marginal investor is an endogenous noise trader. Such a trader anticipates that future shocks may force him to exit his position. In compensation he requires a higher return. We show that the original seller of the asset pays the...

This paper studies the stability of nonlinear autoregressive models with conditionally heteroskedastic errors. We consider a nonlinear autoregression of order p (AR(p)) with the conditional variance specified as a nonlinear first order generalized autoregressive conditional heteroskedasticity...

This study presents new homogenous series of top income shares in Sweden over the period 1903 to 2004. We find that, starting from higher levels of inequality than in other Western countries, the income share of the Swedish top decile drops sharply over the first eighty years of the century. The...

We study the effect of political polarization on public spending using the dispersion of self-reported political preferences as our measure of polarization. Political polarization is strongly associated with smaller government in democratic countries, but there is no relationship between...

In (Viossat, 2006, The replicator dynamics does not lead to correlated equilibria, forthcoming in Games and Economic Behavior), it was shown that the replicator dynamics may eliminate all pure strategies used in correlated equilibrium, so that only strategies that do not take part in any...

This paper decomposes the rise in cross-sectional earnings inequality in Sweden between 1990 and 2002 into changes in market prices of observable characteristics, changes in the composition of the labor force across demographic groups and industries, and changes in unobservables, and compares...

This paper contains a survey of univariate models of conditional heteroskedasticity. The classical ARCH model is mentioned, and various extensions of the standard GARCH model are highlighted. This includes the Exponential GARCH model. Stochastic volatility models remain outside this review.

This paper poses three fundamental questions about lifetime employment in Japan: How big is it? How unique is it? And, how is it changing? I examine different concepts and methods for estimating lifetime employment and conclude that it covers roughly 20 percent of the Japanese labor force. Job...

It is shown in this study that in the case of vertically differentiated products, Bertrand competition at the retail level does not prevent an incumbent upstream firm from using exclusivity contracts to deter the entry of a more efficient rival, contrary to what happens in the homogenous product...

Would you go to the dentist more often if it were free? Observational data is here used to analyze the impact of full-coverage insurance on dental care utilization using different identification strategies. The challenge of assessing the bite of moral hazard without an experimental study design...
