Nominal rigidities and the dynamic effects of a shock to monetary policy

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these features, the most important are staggered wage contracts of average duration three quarters, and variable capital utilization.Monetary policy

Factor demand linkages, technology shocks, and the business cycle

This paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks. We show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural VARs. When sectoral interactions are explicitly accounted for, a contemporaneous technology shock to all manufacturing sectors implies a positive response in both output and hours at the aggregate level. Otherwise there is a negative correlation, as in much of the existing literature. Furthermore, we find that technology shocks are important drivers of the business cycle

A model of a small open economy integrated in a monetary union

This paper develops a model of a small open economy integrated in a monetary union, which is a nontrivial technical extension of the existing small open economy model. The model is used to study the monetary transmission mechanism in Portugal.info:eu-repo/semantics/publishedVersio

Modeling Money

We develop and implement a limited information diagnostic strategy for assessing the plausibility of monetary business cycle models. Our strategy focuses on a model's ability to reproduce empirical estimates of an actual economy's response to monetary policy shocks. A key input to this diagnostic is a univariate time series representation of the response of money to a shock in monetary policy. We find that a monetary policy shock has only a small contemporaneous effect on the monetary base and M1. Its primary effect is to signal future movements in the money supply. We implement our diagnostic strategy on a limited participation model of money which stresses the importance of credit market frictions in the monetary transmission mechanism.

Sticky Price and Limited Participation Models of Money: A Comparison

This paper provides new evidence that models of the monetary transmission mechanism should be consistent with at least the following facts. In response to a contractionary monetary policy shock, the aggregate price level responds very little, aggregate output falls, interest rates initially rise, real wages decline, though by a modest amount, and profits fall. The paper argues that neither sticky price nor limited participation models can convincingly account for these facts. The key failing of the sticky price model is that it implies profits rise after a contractionary monetary policy shock. This finding is robust to a variety of perturbations of the benchmark sticky price model that we consider. In contrast, the limited participation model can account for all of the facts mentioned above. But it can do so only if one is willing to assume a high labor supply elasticity (2) and a high average markup (40%). The shortcomings of both models reflect the absence of other frictions, such as wage contracts, which dampen movements in the marginal cost of production after a monetary policy shock.
