Abstract.  This paper contains the first cross‐country comparison of the cyclical behaviour of real wages using microdata. After controlling for changes in labour quality, I find that real wages are strongly procyclical in Canada, the United Kingdom, and the United States. In contrast, the cyclicality of government‐published real aggregate hourly wages varies substantially across these three countries. The disparity suggests that a direct comparison of the cyclical behaviour of real aggregate wages is misleading. Finally, I show that variations in labour quality also bias the cross‐country correlation of several key labour market variables. JEL classification: J3, E3Une comparaison transversale entre pays du caractère cyclique des salaires réels.  Ce mémoire présente la première comparaison entre pays du comportement cyclique des salaires réels à l'aide de micro‐données. Après normalisation pour tenir compte des changements dans la qualité du travail, cette étude montre que les salaires réels sont pro‐cycliques au Canada, au Royaume‐Uni et aux Etats Unis. Au contraire, le caractère cyclique des données sur les salaires horaires agrégés varie substantiellement entre ces trois pays. Cette disparité suggère qu'une comparaison directe du comportement cyclique des salaires réels agrégés peut être trompeuse. Finalement, cette étude montre que les variations dans la qualité du travail biaisent aussi les corrélations entre pays de plusieurs variables du marché du travail.

Abstract.  This paper studies how donations respond to unexpected permanent changes in income and tax rates in a recursive dynamic model. The dynamic approach yields several interesting insights. If marginal tax rates are progressive, a permanent jump in a household's income increases its consumption and donations in the short run, but has no effect in the long run. The permanent income elasticity of current donations is likely to exceed one. If the marginal tax rate is flat, the jump in income raises consumption and donations in both the short and the long run. A permanent marginal tax rate cut raises consumption and donations in the long run if marginal tax rates are progressive, while it reduces donations in the short run if it has little direct impact on tax payments. If the marginal tax rate is flat, a tax cut has a positive effect on consumption in both the short and the long run, but has an ambiguous effect on donations.

AbstractWe show that the prevalence of prolonged tennis contests drops sharply when the ambient environment deteriorates through heat or pollution. We develop a multi‐battle dynamic model to investigate how the disutility from a protracted competition shapes agents' willingness to fight on. Our theory predicts that a poor environment amplifies the momentum of a competitor's head start. We show how model primitives including preferences for environmental amenities can be inferred from battle‐to‐battle transition probabilities. We find that heat and pollution affect incentives to compete strategically. In a contest between equally able rivals at the median prize of $15,100, the value of a head start is $130‐370 higher in a degraded environment compared with a climate‐controlled one.
