There is much confusion in the economics literature on wage determination and the employment–inflation trade-off. Few model builders pay as much careful attention to the definition and meaning of long-run concepts as did Albert Ando. Expanding on years of painstaking work by Ando, the...

Policy evaluation based on the estimation of dynamic stochastic general equilibrium models rests on the assumption that a representative agent can be identified, whose behavioural parameters are policy-independent. Building on earlier work by Geweke [1985], this paper shows that in the presence...

Should euro-area economies be modelled in an aggregate (area-wide) fashion or in a disaggregate (multi-country) one? This article tackles that question from both statistical and economic viewpoint. From a statistical viewpoint, aggregation bias criteria are found to signal that the degree of...
