What ties together the traditional commercial banking activities of deposittaking and lending? We argue that since banks often lend via commitments, their lending and deposit-taking may be two manifestations of one primitive function: the provision of liquidity on demand. There will be synergies between the two activities to the extent that both require banks to hold large balances of liquid as...

We investigate how the inability to continuously trade an asset affects portfolio choice. We extend the standard Merton model to include an illiquid asset that can only be traded at infrequent, stochastic intervals. Because consumption is financed through liquid wealth only, the presence of illiquidity leads to increased and state-dependent risk aversion. Illiquidity leads to under-investment i...

——————————————————————————————————— We develop a model where agents can allocate their wealth between a liquid asset, which can be used to purchase consumption goods, and an illiquid asset, which represents a better store of value. Should a consumption opportunity arise, agents may visit a frictional “over-the-counter” secondary asset market where they can exchange illiquid for liquid assets. W...

Are securities markets more liquid when the economy is more liquid? If so, why? One possibility is that market depth depends on credit constrained intermediaries. This paper offers another explanation, which does not involve frictions or market segmentation. Measuring market illiquidity by the slope of the representative agent’s demand curve for a risky asset, I show that this slope is steeper ...

The value chain for energy and other commodities entails physical conversions through refineries, power plants, storage facilities, and transportation and other capital-intensive infrastructure. When the operation of such commodity conversion assets occurs alongside liquid markets for the input and output commodities, the operating flexibility of conversion assets can be managed as real options...
