This paper studies consumption/saving problem under Knightian uncer- tainty in a two period setting. The multiple-priors utility model is adopted. The e®ects of income uncertainty and capital uncertainty on optimal savings are analyzed by deriving closed form solutions.

What is the long-run effect of dividend taxation on aggregate capital accumulation? To address this question, we build a dynamic general equilibrium model in which there is a continuum of firms subject to idiosyncratic productivity shocks. This firm heterogeneity generates a cross-sectional...

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial finance to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...

This paper presents an analytically tractable continuous-time general equilibrium model with investment irreversibility and fixed adjustment costs. In the model, there is a continuum of firms that are subject to idiosyncratic shocks to capital. Although the presence of investment frictions...

We study an investor's optimal consumption and portfolio choice problem when he confronts with two possibly misspecified submodels of stock returns: one with IID returns and the other with predictability. We adopt a generalized recursive ambiguity model to accommodate the investor's aversion to...
