This paper presents a tractable dynamic general equilibrium model of income and firm-size distributions. The size and value of firms result from idiosyncratic, firm-level productivity shocks. CEOs can invest in their own firms¡¯ risky stocks or in risk-free assets, implying that the CEO's...

This paper presents a dynamic general equilibrium model with heterogeneous firms and entrepreneur's portfolio choice. We analytically show that this model generates the Pareto distribution of top income earners and Zipf's law of firms at the steady state. The differential equation for the...

We construct a neoclassical growth model with heterogeneous households that accounts for the Pareto distributions of income and wealth in the upper tail. In an otherwise standard Bewley model, we feature households' business productivity risks and borrowing constraints, which we find generate...

We construct a tractable neoclassical growth model that generates Pareto's law of income distribution and Zipf's law of the firm size distribution from idiosyncratic, firm-level productivity shocks. Executives and entrepreneurs invest in risk-free assets as well as their own firms' risky stocks,...
