This paper is devoted to fiscal shock identification based on the assumption of nonGaussianity of the errors, which can be easily tested. We use additional co-kurtosis conditions in GMM estimation of the AB-model to estimate the dynamic effects of fiscal shocks and find fiscal multipliers in the...

The inefficiencies related to endogenous product creation and variety under monopolistic competition are two-fold: one static—the misalignment between consumers and producers regarding the value of a new variety; and one dynamic—time variation in markups. Quantitatively, the welfare costs of...
