opposite is the case with markups. If they increase in reaction to higher prices, they contribute to further price increases …

factor prices has a positive effect on markups. We show theoretically that firms with higher shares of inputs with volatile … prices set higher markups. We use the Bartik shift-share approach to empirically test whether firms which use more oil … relative to other inputs set higher markups when oil prices are more volatile. Our estimates imply that a one standard …

Inflation affects the purchasing power of households. This paper documents large, idiosyncratic inflation differences … between households in their everyday shopping. Low-income households have experienced higher inflation in the last ten years … inflation differences within countries. Between countries, multinational retail chains not only differentiate products by …

We analyse the incidence of endogenous entry and firm TFP-heterogeneity on the response of aggregate inflation to … distribution of firms in Spain. We then compare the inflation response to technology, interest rate and entry cost shocks, among … others. We find that structures in which large (more productive) firms predominate tend to deliver more muted inflation …

consequences for the analysis of inflation dynamics, modifying in particular the inflation-marginal cost relationship. As a general …

In this paper we study the theoretical plausibility of the conjecture that inflation arises because imperfectly … inflation transmission. We compared these measures in several models of ICM and in perfectly competitive markets (PCM in the … sequel). In each case we find a necessary and sufficient condition for an ICM to transmit more inflation - according to the …

inflation compared to industries with low-competition in the past few years. Further investigation shows that this …-competition have higher annual producer price inflation on average than those that are characterized with high-competition especially …
