Capital Income Risk and the Dynamics of the Wealth Distribution IZA Discussion Paper No. 11840, Institute for the Study of Labor (IZA), September 2018.

In this paper, we develop and numerically solve a model of idiosyncratic labour income and idiosyncratic interest rates to predict the evolution of a wealth distribution over time. Stochastic labour income follows a deterministic growth trend and it fluctuates between a wage and unemployment benefits. Stochastic interest rates are drawn initially (ex-ante heterogeneity), fluctuate between two values (ex-post heterogeneity) and can differ in their arrival rates (financial types). A low interest rate implies a stationary long-run wealth distribution, a high interest rate implies non-stationary wealth distributions. Our baseline model matches the evolution of the wealth distribution of the NLSY 79 cohort from 1986 to 2008 very well. When we start in 1986 and target 2008, we obtain a fit of 96.1%: The fit for non-targeted years is 77.0% on average. When targeting the evolution of wealth, the fit is 88.9%. With a more flexible interest rate distribution, the fit can even be increased to 96.7%. Comparing calibrated mean returns with data shows that the flexible interest rate distribution has empirically not convincing "superstar states". In the baseline model, mean returns are empirically convincing. Surprisingly, the standard deviation of model returns is an order of magnitude lower than the empirical standard deviation. |

Capital Income Risk and the Dynamics of the Wealth Distribution Economic Modelling 122 (May 2023): 106243. Also: https://www.sciencedirect.com/science/article/pii/S026499932300055X Cohort(s): NLSY79 Publisher: Elsevier Keyword(s): Income Risk; Wealth Understanding rising wealth inequality requires a comprehension of the evolution of wealth distributions. We quantify a model of idiosyncratic labor income and interest rates to match the evolution of the wealth distribution of the NLSY 79 cohort in the US from 1986 to 2008. We allow for economic growth, stochastic labor income and stochastic interest rates. Individuals differ in their financial ability, i.e. in their average financial returns. Aggregating over individuals balances a stationary long-run wealth distribution (for low interest rates) with exploding wealth distributions (for high interest rates). The baseline calibration fits the wealth distribution in 2008 up to 96.1% with an empirically plausible distribution of labor income and the standard deviation of model interest rates being lower than the empirical standard deviation. As our average fit over the entire sample period is also very good, models of this type can be employed to understand how quickly wealth distributions could become more equal if certain policy measures were introduced. |
