Discounting future costs and benefits is a crucial yet contentious practice in the appraisal of long-term public projects with environmental consequences. The standard approach typically neglects that ecosystem services are not easily substitutable with manufactured goods and often exhibit...

This paper models and estimates total factor productivity (TFP) growth parametrically. The model is a generalization of the traditional production model where technology is represented by a time trend. TFP growth is decomposed into unobservable technical change, scale economies and observable...

Can the standard search-and-matching labor market model replicate the business cycle fluctuations of the job finding rate and the unemployment rate? In the odel, these fluctuations are driven by movements in productivity. This paper inestigates the sources of productivity fluctuations that are...
