What is the optimal size of expert committees? To address this question, I present a model of a committee of experts with career concerns. Each expert may observe an argument about the state of the world and is unsure about the arguments soundness. Experts may remain silent or compete for the...

We propose a signaling model in which the central bank and firms receive information on cost-push shocks independently from each other. If the firms’ signals are rather unlikely to be informative, central banks should remain silent about their own private signals. If, however, firms are...

We introduce the notion of verifiable information into a model of sequential debate among experts who are motivated by career concerns. We show that self-censorship may hamper the efficiency of information aggregation, as experts withhold evidence contradicting the conventional wisdom. In this...

In this paper we examine a model where firms decide on the intensity of information acquisition about shocks. We analyze how the monetary policy framework impacts on the aggregate amount of information collected by firms. We show that it is socially beneficial to delegate monetary policy to a...

In this paper we present a two-period model where a left-wing and a right-wing political party are solely interested in the politics they pursue. We assume that voters are fully rational but show reciprocal behavior. By contrast, political parties are not motivated by reciprocity. We show that...

The new Keynesian literature typically makes the assumption that firms always have to satisfy demand, which is at odds with profit‐maximizing behavior under Calvo pricing when long‐run inflation is positive. Our model, which relaxes this assumption, predicts that inflation causes a...
