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,...

What is the effect of non-tradeable idiosyncratic risk on asset-market risk premiums? Constantinides and Duffie (1996) and Mankiw (1986) have shown that risk premiums will increase if the idiosyncratic shocks become more volatile during economic contractions. We add two important ingredients to...

Financing government spending through lump sum taxes does not distort capital when markets are complete but tends to increase precautionary savings under market incompleteness. Using flat consumption taxes instead leaves precautionary savings unaffected, provided certain conditions on utility...

The large wealth and consumption inequality in the U.S. is usually attributed to two market frictions: debt constraints and incomplete markets. Recent literature has argued that debt constraints are the critical friction while market incompleteness plays only a secondary role. We evaluate the...

Entrepreneurs often face undiversifiable idiosyncratic risks from their business investments. We extend the standard real options approach to an incomplete markets environment and analyze the joint decisions of business investments, consumption/savings, and portfolio selection. For a lump-sum...

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,...
