We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

This article assesses economic growth in the context of consumer saturation. We show that consumer based economies tend to suffer from demand saturation after an initial and prolonged period of growth. However, structural demand saturation irrevocably triggers a Minsky-type super cycle that is...

We develop a search-matching model, where firms search for customers (e.g. in form of advertising). Firms use long-term contracts and bargain over prices, resulting in a price mark up above marginal cost, which is procyclical and depends on firms' relative bargaining power. Product market...

This note studies the inflation-uncertainty relationship in a New Keynesian framework. Inflation in these models can be expressed as the discounted sum of current and expected future real marginal costs. The main point of this note is to highlight that real marginal costs in general equilibrium...

This paper develops a search-matching model, where producers provide effort to find customers (e.g. in form of advertising and marketing expenditures). Firms form long-term contractual relationships and bargain over prices. The price bargain results in mark up pricing above marginal cost. The...

This paper compares Taylor-style staggered price setting to partial adjustment of prices (or Calvo staggering) in a small optimizing IS/LM model. In contrast to the overwhelming perception in the literature, the models are not similar for most parameterizations. In particular, the dynamic...

This paper emphasizes the notion that model features that contribute to endogenous price rigidity under staggered price setting lower the elasticity of marginal cost with respect to output, and these same model features tend to generate equilibrium indeterminacy, or "sunspot fluctuations," under...

This paper investigates the dynamics of output, employment and prices in an economy with costs of adjusting labor and prices. In an economy with non-convex adjustments costs, firms do not adjust labor and prices continuously to accommodate every shift in demand. Rather, firms adjust employment...

We study the macroeconomic effects of the COVID-19 epidemic in a quantitative dynamic general equilibrium setup with nominal rigidities. We evaluate various containment policies and show that they allow to dramatically reduce the welfare cost of the disease. Then we investigate the role that...

The COVID-19 pandemic has led to an unprecedented shift of consumption from services to goods. We study this demand reallocation in a multi-sector model featuring sticky prices, input-output linkages, and labor reallocation costs. Reallocation costs hamper the increase in the supply of goods,...
