The New Keynesian Phillips curve (NKPC) is now the dominant model of inflation dynamics. In recent years, a large body of empirical research has documented price-setting behaviour at the individual level, allowing the assessment of the micro-foundations of pricing models. This paper analyses the...

Previous studies have stressed that inflation dynamics exhibit a substantial dispersion across sectors. Using US producer price data, we present evidence that sectoral inflation persistence is negatively correlated with market concentration, which is difficult to reconcile with the prediction of...

This paper surveys the current state of global empirical research on price setting behaviour at the firm level to evaluate the adequacy of pricing models used in the macro literature. To that end, it analyses the implications of 25 theoretical models (sticky information, menu costs, time...

Operating profit is a good approximation of long term average profit, and it is an indicator much more widely used than marginal profit in market practice. The economic growth can be explained by adding up all the firms' revenues, costs and profits without any more hypotheses. The unemployment...

This paper presents an equation of the dynamic path of prices in a monopolistically competitive market in which firms sell to both old and new customers. Both types are able to search for the lowest price, given search costs, where the expected number of searches is given by the inverse of the...

We estimate the pass-through of a cost-push wage shock to producer prices of firms in Denmark. We deal with the endogeneity of wages by using an identification strategy based on variation in the estimated outside option of workers within an industry. Our results suggest that the pass-through...

Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...
