We compute the impulse response of output to an aggregate monetary shock in a general equilibrium when firms set prices subject to a costly observation of the state and a menu cost. We study how the aggregate effects of a monetary shock depend on the relative size of these costs. We find that...

We model the pricing decisions of a multi-product firm that faces a fixed 'menu' cost: once the cost is paid, the firm can adjust the price of all its products. We characterize analytically the steady state firm’s decision in terms of the structural parameters: the variability of the flexible...

To capture location shifts in the context of model selection, we propose selecting significant step indicators from a saturating set added to the union of all of the candidate variables. The null retention frequency and approximate non-centrality of a selection test are derived using a...
