Liquidity risk in banking has been attributed to transactions deposits and their potential to spark runs or panics. We show instead that transactions deposits help banks hedge liquidity risk from unused loan commitments. Bank stock-return volatility increases with unused commitments, but the...

This paper argues that banks have a unique ability to hedge against market-wide liquidity shocks. Deposit inflows provide funding for loan demand shocks that follow declines in market liquidity. Consequently, one dimension of bank specialness' is that banks can insure firms against systematic...

Transaction costs in trading involve both risk and return. The return is associated with the cost of immediate execution and the risk is a result of price movements during a more gradual trading. The paper shows that the trade-off between risk and return in optimal execution should reflect the...

This paper discusses the fundamental underpinnings and some implications of transaction cost regulation (TCR), a framework to analyze the interaction between governments and investors fundamentally, but not exclusively, in utility industries. TCR sees regulation as the governance structure of...

This note describes the unraveling of transaction dates in several markets, including the labor markets for new lawyers hired by large law firms and for gastroenterology fellows, and the market for post-season college football bowls. Together these will illustrate that unraveling can occur in...

We apply numerical dynamic programming to multi-asset dynamic portfolio optimization problems with proportional transaction costs. Examples include problems with one safe asset plus two to six risky stocks, and seven to 360 trading periods in a finite horizon problem. These examples show that it...

Contractual theories of vertical integration derive firm boundaries as an efficient response to market transaction costs. These theories predict a relationship between underlying features of transactions and observed integration decisions. There has been some progress in testing these...

I examine Ronald Coase's criticism of standard regulatory and tax policies to address environmental externalities. I elaborate some of Coase's key points and discuss opportunities for Coasean exchange as an alternative mitigation approach. Regulation, tax, and Coasean exchange, such as through...

This paper examines the factors that give rise to intermediaries in exporting and explores the implications for trade volumes. Export intermediaries such as wholesalers serve different markets and export different products than manufacturing exporters. In particular, high market-specific fixed...

We examine how liquidity and asset prices are affected by the following market imperfections: asymmetric information, participation costs, transaction costs, leverage constraints, non-competitive behavior and search. Our model has three periods: agents are identical in the first, become...
