This paper solves for optimal international portfolio choice in the presence of liquidity constraints and undiversifiable labor income risk. Optimal portfolios are internationally diversified while positive correlation between domestic stock market returns and permanent labor income shocks can...

This paper solves numerically for the optimal consumption and portfolio choice of an infinitely lived investor facing short-sales and borrowing constraints, undiversifiable labor income risk and a predictable time varying equity premium. The investor aggressively times the market while positive...

We study by theoretical analysis and by direct numerical simulation the dynamics of a wide class of asynchronous stochastic systems composed of many autocatalytic degrees of freedom. We describe the generic emergence of truncated power laws in the size distribution of their individual elements....

The recent literature on economic growth and business cycles, such as Helpman and Trajtenberg (1996), Hornstein and Krusell (1996), Jovanovic and Lack (1997), and Andolfatto and MacDonald (1998), shows that the diffusion of new technology is important in accounting for some features of aggregate...

Effective monitoring of a minimum wage, requires that establishments potentially paying low wages are effectively identified. This paper investigates the identification of establishments paying low wages prior to the introduction of the British National Minimum Wage in 1999, through the...
