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...

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...

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...

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...

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...

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...

Despite their potentially strong impact on poverty, agricultural innovations are often adopted slowly. Using a unique household dataset on sunflower adoption in Mozambique, we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks....

Individuals and business owners engage in an increasingly complex array of financial decisions that are critical for their success and well-being. Yet a growing literature documents that in both developed and developing countries, a large fraction of the population is unprepared to make these...

The determinants of government responsiveness to its citizens is a key issue in political economy. Here we develop a model based on the solution of political agency problems. Having a more informed an politically active electorate strengthens incentives for governments to be responsive. This...
