This paper analyses whether sovereign default episodes can be seen as contingencies of optimal international lending contracts. The model considers a small open economy with capital accumulation and without commitment to repay debt. Taking first order approximations of Bellman equations, I...

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...

The processes of building the United States of America (USA) during the nineteenth century and the European Union (EU) since mid-twentieth century are among the major claims for the possibility of a vast, ‘imperial’-size political unit based on democratic principles. The crucial period for...

We present a dynamic comparative advantage model in which moderate reductions in trade costs can generate sizable increases in trade volumes over time. A fall in trade costs has two effects on the volume of trade. First, for given factor endowments, it raises the degree of specialization of...

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 aims at providing a conceptual distinction between banking and insurance with regard to systemic regulation. It discusses key differences and similarities as to how both sectors interact with the financial system. Insurers interact as financial intermediaries and through financial...

This article estimates the effect of visa restrictions on bilateral trade flows and foreign direct investment (FDI) stocks. By raising the costs of travel and deterring some visitors, visa restrictions hamper personal contact across borders, which is detrimental to trade and FDI. Employing a...

This paper provides a survey of results on the quantiles of a Brownian motion with drift as well as a general Lévy process. The motivation is to calculate the price of related financial options. At the end of the paper some new results on variability orderings between various quantities...
