The paper examines how the long-run inflation-unemployment tradeoff depends on the degree to which wage-price decisions are backward- versus forward-looking. When economic agents, facing time-contingent, staggered nominal contracts, have a positive rate of time preference, the current wage and...

This paper sheds light on how changes in the organization of work lead to wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the span of competence are...

This paper argues that an important group of labor market policies are complementary in the sense that the effect of each policy is greater when implemented in conjunction with the other policies than in isolation. This may explain why the diverse, piecemeal labor market reforms in many European...

This paper analyzes socially optimal responses of environmental targets (i.e. targets on pollutant flows) to different types of technological progress. with reference to a simple macro-economic model including production, pollution generation, and pollution treatment, a socially optimal temporal...
