Given the political and public interest in rising industry concentration in developed economies, researchers have been working on uncovering underlying mechanisms and implications. Various causes of concentration have been proposed, although rarely tested in a comprehensive model. We study five...

This paper introduces a New Keynesian multi-sector industry model that integrates firm heterogeneity, entry, and exit dynamics, while considering energy production from both fossil fuels and renewables. We investigate the effects of a sustained increase in fossil fuel prices on sectoral size,...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing as its productivity increases....

This paper studies the market and welfare effects of income heterogeneity in monopolistically competitive product markets in the context of nonhomothetic preferences. In a closed economy, where richer individuals' expenditures are less sensitive to price change compared to poorer ones', a...

We assess the role of cognitive convenience in the popularity and rigidity of 0-ending prices in convenience settings. Studies show that 0-ending prices are common at convenience stores because of the transaction convenience that 0-ending prices offer. Using a large store-level retail CPI data,...

The Covid-19 pandemic had different impacts across the globe, according to both country structure and conjunctural responses from local governments. This article aims to characterize the main traits of capitalism in Brazil, with a focus on its evolution over the last 20 years and the way these...

Structural change is an important driver of productivity growth at the aggregate level. While previous productivity decompositions account for the contributions of market entry and exit, they overlook continuing firms that switch from one industry to another. We develop an improved productivity...

Inflation is painful, for firms, customers, employees, and society. But careful study of periods of hyperinflation point to ways that firms can adapt. In particular, companies need to think about how to change prices regularly and cheaply - because constant price changes can ultimately be very,...

We study the price rigidity of regular and sale prices, and how it is affected by pricing formats (i.e., pricing strategies). We use data from three large Canadian stores with different pricing formats (Every-Day-Low-Price, Hi-Lo, and Hybrid) that are located within a 1 km radius of each other....
