The interest rate is a key determinant of firm investment. We integrate a widely used term structure model of interest rates, CIR (Cox, Ingersoll, and Ross (1985)), with the q theory of investment (Hayashi (1982) and Abel and Eberly (1994)). We show that stochastic interest rates have...

We develop an analytically tractable consumption-savings model for a liquidity-constrained agent who faces both permanent and transitory income shocks. We find that risk aversion and intertemporal substitution have very different effects on both consumption and the steady-state savings target....

We study the impact of stochastic interest rates and capital illiquidity on investment and firm value by incorporating a widely used arbitrage-free term structure model of interest rates into a standard q theoretic framework. Our generalized q model informs us to use corporate credit-risk...

"An entrepreneur faces substantial non-diversifiable business risk and liquidity constraints, both of which we refer to as frictions. We show that these frictions have significant economic effects on business start-up, capital accumulation/asset sales, portfolio allocation, consumption/saving,...

An entrepreneur faces non-diversifiable business risk and liquidity constraints. We provide a unified framework that embeds these frictions to study interdependent business start-up/entry, capital accumulation/asset sales, portfolio allocation, consumption/saving, and business exit decisions....
