Executive stock options reward success but do not penalise failure. In contrast, the standard principalagent model implies that pay is normally monotonically increasing in performance. This paper shows that, under loss aversion, the use of carrots but not sticks is a feature of an optimal...

Compensation schemes often reward success but do not penalize failure. Fixed salaries with stock options or bonuses have this feature. Yet the standard principal–agent model implies that pay is normally monotonically increasing in performance. This paper shows that, under loss aversion, there...

This paper presents a model with monopolistic competition, productively heterogeneous firms, and business cycle aggregate shocks. With firm-specific productive heterogeneity, weaker firms quit when faced with a negative aggregate shock. Consequently, trade does not always increase firm-level...

Andy Rose (2000), followed by many others, has used the gravity model of bilateral trade on a large data set to estimate the trade effects of monetary unions among small countries. The finding has been large estimates: Trade among members seems to double or triple, that is, to increase by...

This paper analyzes the theoretical underpinnings of high-frequency repayment, a feature in nearly all microfinance contracts that has been largely overlooked by theorists. The pervasive belief among practitioners that frequent repayment is critical in achieving high repayment rates is puzzling....

Theory suggests that government should as far as possible smooth taxes and its recurrent consumption spending, which means that government debt should act as a shock absorber, and any planned adjustments in debt should be gradual. This suggests that operational targets for governments (e.g. for...
