We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies...

We show how to relate the welfare of a country's infinitely-lived representative consumer to observable aggregate data. To a first order, welfare is summarized by total factor productivity and by the capital stock per capita. These variables suffice to calculate welfare changes within a country,...

Why do countries delay stabilizations of large and increasing budget deficits and inflation? And what explains the timing of reforms? We use the war of attrition model as a guidance for our empirical study on a vast sample of countries. We find that stabilizations are more likely to occur when...

Why do countries delay stabilizations of large and increasing budget deficits and inflation? And what explains the timing of reforms? We use the war-of-attrition model to guide our empirical study on a vast sample of countries. We find that stabilizations are more likely to occur when times of...

Can increased uncertainty about the future cause a contraction in output and its components? This paper examines the role of uncertainty shocks in a one-sector, representative-agent dynamic stochastic general-equilibrium model. When prices are flexible, uncertainty shocks are not capable of...

Nominal wage stickiness is an important component of recent medium-scale structural macroeconomic models, but to date there has been little microeconomic evidence supporting the as- sumption of sluggish nominal wage adjustment. We present evidence on the frequency of nominal wage adjustment...
