In an otherwise unique-equilibrium model, agents are segmented into a few informational islands according to the signal they receive about others' expectations. Even if agents perfectly observe fundamentals, rational-exuberance equilibria (REX) can arise as they put weight on expectational...

This article provides evidence about the interrelationships between wages and prices at the microeconomic level. We rely on the right-to manage model to specify and estimate a multivariate model explaining the timing and magnitude of wage changes at the firm level. The modeling of price changes...

This paper offers a comprehensive comparison of the structure of banking and financial markets in the euro area. Based on this, several hypotheses about the role of banks in monetary policy transmission are developed. Many of the predictions that have been proposed for the U.S. are deemed...

The aim of this paper is to check the possible existence of a bank lending channel in France. For that purpose, we have estimated a dynamic reduced form model allowing for asymmetries in loan supply across banks, depending on their size, liquidity and capitalization. We have used a panel of 312...

This paper presents a simple model of state-dependent pricing that allows identification of the relative importance of the degree of price rigidity that is inherent to the price setting mechanism (intrinsic) and that which is due to the price's driving variables (extrinsic). Using two data sets...

Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth. This paper uses the theory and methodology developed by Aghion et al. (2017) to quantify in the case of France how much of...

This paper provides the conditions under which small enough private uncertainty on an aggregate endogenous state of the economy can invalidate uniqueness of the equilibrium. The main result is presented in a fully microfounded macroeconomic model where agents learn from arising prices. The...

We show that an increase in banks' holdings of domestic Sovereign debt decreases the ability of domestic Sovereigns to successfully enact bailouts. When Sovereigns finance bailouts with newly issued debt and the price of Sovereign debt is sensitive to unanticipated debt issues, then bailouts...

Growth has fallen in the U.S., while firm concentration and profits have risen. Meanwhile, labor's share of national income is down, mostly due to the rising market share of low labor share firms. We propose a theory for these trends in which the driving force is falling firm-level costs of...
