Previous studies have stressed that in ation dynamics exhibit a substantial disper- sion across sectors. Using US producer price data, we present evidence that sectoral in ation persistence is negatively correlated with market concentration, which is diffi- cult to reconcile with the prediction...

Monetary policy is most effective when public beliefs about future policies are actively managed. This is the appeal of policy rules and commitment strategies, typically absent under discretion. But when a policymaker has some private information - as is the case in reality - belief management...

We study optimal nominal demand policy in an economy with monopolistic competition and flexible prices when firms have imperfect common knowledge about the shocks hitting the economy. Parametrizing firms' information imperfections by a (Shannon) capacity parameter that constrains the amount of...

The aim of this study is to assess the extent to which the degree of heterogeneity of inflation expectations is driven by the flow of information related to current and future price developments. To that end, we follow three routes: i) We propose different measures of information flow that have...

This paper develops an algorithm that enables to solve macroeconomic models with Rotemberg pricing and imperfect common knowledge. Under the concept of imperfect common knowledge, Rotemberg pricing requires the solution algorithm to take prices explicitly into account. The state space includes...

This paper decomposes price into its 2 major constituents, namely markup (Mkp) and marginal cost (MC) with which a Markov-switching VAR with fixed transition probabilities is estimated. Since the proposed pair of variables has not been extensively analysed, a theoretical model that derives...

This paper develops an algorithm that enables to solve macroeconomic models with Rotemberg pricing and imperfect common knowledge. Under the concept of imperfect common knowledge, Rotemberg pricing requires the solution algorithm to take prices explicitly into account. The state space includes...

Using theoretical and empirical analyses, this paper shows that the expectation dynamics induced by information asymmetry between the Central Bank (CB) and the public can cause the price puzzle. The signalling and learning dynamics between the CB and a representative private-sector agent under...

A model of dynamic risk-sharing is constructed where agents meet pairwise and at random, and there is private information about endowments. Risk sharing is accomplished through dynamic contracts involving credit transactions and through monetary exchanges. A Friedman rule is optimal, and...

This paper examines the impact of public information in an economy where agents also have diverse private information. Since disclosures by central banks are an important source of public information, we are able to assess how the words of central bankers shape expectations, in addition to their...
