We find that demand shocks play an important role for business-cycle fluctuations in unemployment and job vacancies. The reason is that those shocks give a strong incentive to demand-constrained firms to adjust production and thereby labor input. Furthermore we argue that whether real wage rigidity à la Hall [2005. Employment fluctuations with equilibrium wage stickiness. American Economic Revi...

This paper studies a two-sector New Keynesian model that captures the hump-shaped response of non-durable and durable spending to a monetary shock when non-durable prices are sticky and durable goods are flexibly priced. Based on the estimated parameters, we show that habit formation and investment adjustment costs are not sufficient to generate the gradual response of non-durable and durable s...

They do not necessarily equilibrate...

This is a very interesting paper about the role of money in monetary-policy analysis (Nelson (2003)). Ed Nelson is the ideal author of such a paper. He is a master of modern monetary economics, including New Keynesian analysis, being a student of Ben McCallum’s and a coauthor with Ben of some of the pioneering contributions to the New Keynesian literature. Ed is also a master of more traditiona...
