Resumen
Kimball (1990a,b) established that income risk increases the marginal propensity to consume if and only if absolute prudence decreases. We characterize decreasing and increasing multivariate prudence and show that a multidimensional risk increases the marginal propensity to consume if and only if absolute prudence decreases with wealth, in the sense that its derivative is negative-definite.
