This paper develops a two-sector model of growth where agriculture is considered explicitly. Key features of the model include: the reliance of agricultural production on a fixed but degrading resource base, the use by the farm sector of industrially produced inputs and differing rates of...

The accuracy of the solution of dynamic general equilibrium models has become a major issue. Recent papers, in which second-order approximations have been substituted for first-order, indicate that this change may yield a significant improvement in accuracy. Second order approximations have been...

We investigate the implications of changes in the structure of the US economy for monetary policy effectiveness. Estimating a VAR over the pre- and post-1980 periods, we provide evidence of a reduced effect of monetary policy shocks in the latter period. We estimate a structural model that...

A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and I concentrate on the numerics and...

Standard asset pricing models have difficulty explaining cross-sectional differences in observed equity risk premia of developed and emerging markets. We argue that national equity returns are subject to sample selectivity and peso biases. The lack of credible commitment to keep capital markets...

Utilizando el modelo dinámico de equilibrio general multisectorial medioambiental de tres regiones EMuSe, encontramos que una tarificación del carbono limitada a Alemania o España solo conduce a un efecto negativo permanente sobre la producción en estas economías. La reducción de emisiones...
