Giffen reported that, in the late nineteenth century, English wheat consumption rose when its price increased – the first recorded “Giffen good”. Using Giffen’s data, I explain how he reached his conclusion. I then show that his analysis was faulty: price elasticity of demand appears...

Using a newly-constructed data set on Israeli Initial Public Offering (IPO) firms in the 1990s, we study costs and benefits of universal banking. We find that a firm whose equity was underwritten by a bank-affiliated underwriter, when the same bank was also a large creditor of the firm in the...

We develop a model of internal governance where the self-serving actions of top management are limited by the potential reaction of subordinates. We find that internal governance can mitigate agency problems and ensure firms have substantial value, even without any external governance. Internal...

We study a continuous time model of a levered firm with fixed assets generating a cash flow that fluctuates with business conditions. Since external finance is costly, the firm holds a liquid (cash) reserve to help survive periods of poor business conditions. Holding liquid assets inside the...

We examine how shareholder investment horizons influence firms’ payout decisions. We find that US firms held by short-term institutional investors have a higher propensity to buybacks shares instead of using dividends. Firm managers seem to respond to the preferred payout policy of investors...

Low domestic saving rates in South Africa may perpetuate a low-growth trap. The decline in government saving, a major reason for the overall decline in saving, is now being reversed. However, personal saving rates have fallen since 1993, and corporate rates since 1995, and both may decline...

Stock-based compensation is the standard solution to agency problems between shareholders and managers. In a dynamic rational expectations equilibrium model with asymmetric information we show that although stock-based compensation causes managers to work harder, it also induces them to hide any...

Recent work has suggested that strategic underperformance of debt-service obligations by equity holders can resolve the gap between observed yield spreads and those generated by Merton-style models. We show that this is not quite correct. The value of the option to underperform on debt-service...

We analyse dynamic financial contracting under moral hazard. The ability to rely on future rewards relaxes the tension between incentive and participation constraints, relative to the static case. Managers are incited by the promise of future payments after several successes and the threat of...

We develop a dynamic model of investment, cash holdings, financing, and risk management policies in which firms face financing frictions and are subject to permanent and temporary cash flow shocks. In this model, target cash holdings depend on the long-term prospects of the firm, implying that...
