Liquidity and Inefficient Investment
نویسندگان
چکیده
We study consumer liquidity in a general equilibrium model where the friction is the nonpledgeability of future income. Liquidity helps to overcome the absence of a double coincidence of wants. Consumers over-hoard liquidity and the resulting competitive equilibrium is constrained inefficient. Fiscal policy following a large negative shock can increase ex ante welfare. If the government cannot commit, the ex post optimal fiscal policy will be too small from an ex ante perspective. The model throws light on the holding of foreign reserves in international markets.

Housing Bubbles and Policy Analysis∗
This paper provides a theory of credit-driven housing bubbles in an infinite-horizon production economy. Entrepreneurs face idiosyncratic investment tax distortions and credit constraints. Housing is an illiquid asset and also serves as collateral for borrowing. A housing bubble can form because houses command a liquidity premium. The housing bubble can provide liquidity and relax credit constr...
متن کاملComposition of International Capital Flows: A Survey
Composition of International Capital Flows: A Survey In this survey, we focus on key mechanisms through which liquidity and financial shocks affect major types of capital flows. We focus on a few models that examine the role of asymmetric information, liquidity preferences, limited enforcement, and incomplete markets on the composition of capital flows. We show that the information asymmetry be...
متن کاملManaging Markets for Toxic
We present a model in which banks trade toxic assets to raise funds for investment. The toxic assets generate an adverse selection problem and, as a consequence, the interbank asset market provides insufficient liquidity to finance investment. Investment is inefficiently low because acquiring funding requires banks to sell high-quality assets for less than their " fair " value. We analyze wheth...
متن کاملLeverage and Liquidity Dry-ups: A Framework and Policy Implications
We model financial market liquidity as provided by financially constrained arbitrageurs. Market liquidity increases with the level of arbitrage capital, i.e., internal and external capital arbitrageurs can access frictionlessly. We show that liquidity dry-ups follow periods of low returns of arbitrageurs’ risky investment opportunities, and that liquidity is correlated across markets. A welfare...
متن کاملLiquidity Preference and Information
This note explores the link between anticipated information and a preference for liquidity in investment choices. Given a subjective ordering of investment portfolios by their liquidity, we identify a sufficient condition under which the prospect of finer resolution of uncertainty creates a preference for more liquid positions. We then show how this condition might arise naturally in some stand...
