Where should the emphasis lie in macroeconometric modelling between the purity of the economic theory and empirical performance? The widespread use of DSGE models estimated by Bayesian methods has been accompanied by a downgrading of the role of statistical fit. This column reviews the issue and concludes that the challenge is to incorporate greater flexibility into the theory in such a way as to be compatible with both the theory and the data.

Debate surrounding the Trans-Pacific Partnership (TPP) is raging. Economists on different sides of the debate have used different arguments and tools to support their positions.

The general results of these studies lend support to those who think that TPP will be beneficial.
