Portfolio choices over the life-cycle and the cyclical skewness of labor income shocks

I estimate a life-cycle model of portfolio choices that incorporates the relationship between market returns and the skewness of idiosyncratic income shocks. The cyclicality of skewness can explain (i) low stock market participation among young households, (ii) why the equity share of participants slightly increases until retirement and (iii) why renters have lower equity shares than homeowners. With a relative risk aversion of 6 and yearly participation cost of \$100, the model matches the evolution of wealth, participation and conditional equity shares over the life-cycle. Nonetheless, cyclical skewness increases the equity premium by at most 0.3 percentage point
