We study the determination of market power at the firm and industry levels when heterogeneous firms compete for sales to ex ante homogeneous buyers in a market with both directed and random search and free entry of firms that differ in productivity. Search and the distribution of productivity...

This paper examines the effect of green investments on market power. I measure the market power as markup following the method provided in De Loecker and Warzynski (2012). For green investments, I consider specifically the investments of firms in energy efficient technologies, both as the binary...

This paper documents changes in investors' demand for sovereign debt during a debt crisis. Using a dataset containing individual bids on Portuguese debt auctions, I document that bid functions become more inelastic during the crisis. That is, investors require bigger drops in price to buy...

We study changes in job reallocation in Europe after 2000 using novel microaggregated data that we collected for 19 European countries. In all countries, we document broad-based declines in job reallocation rates that concern most economic sectors and size classes. These declines are mainly...

This study estimates and decomposes recruitment elasticity, a key measure of employer market power, across job-matching stages using data from Japan's largest job-matching intermediary. On average, recruitment elasticity is negative but not statistically significantly different from zero....

Using register data, we document that the average German labor market, defined by hires in combinations of 3-digit occupations, requirement levels, and commuting zones, is highly concentrated (HHI=0.257). By EU antitrust thresholds, 56 percent of these labor markets feature moderate or high...

Purpose The paper examines the impact of market power on wages within the context of a developing country, focusing on Brazil. Design/methodology/approach With access to matched employer-employee data from Brazil, we first characterized the evolution of the local labor market concentration...

This paper examines the relationship between labor market power and employer discrimination, providing new causal evidence on when and where discriminatory outcomes arise. We leverage mass layoffs and firm closures as a source of exogenous job search and combine this with an exact matching...

The Middle East (ME) is often perceived as region with rentier economies and uncompetitive markets. Evidence of market power in the region however is scant. In this paper, we ask the following three questions: Is the ME uniquely uncompetitive? Has the evolution of market power in the region...

The electricity industry is undergoing a transformative evolution driven by three overarching trends: decentralization, digitalization, and decarbonization (3Ds). To ensure access to clean, affordable, and reliable energy for all by 2030 - UN sustainable development goal 7 (SDG7) - countries...

Research about trade liberalization's impact on markups has focused on manufacturing due to data availability considerations. How do these effects vary across sectors? Which industries become more and less competitive as trade barriers are eliminated? We leverage firm-level tax records from the...

The functioning of the banking sector is key for economic growth. In this paper, we first gather banks' balance sheet monthly regulatory information in a consistent manner for seven Latin American countries. Second, we estimate lending markups and deposits markdowns in each country over time....

This paper examines the relationship between wages and market power at the firm level. We derive firm-specific measures of labor market power and present a natural decomposition of wage changes into shifts in labor market power and labor productivity. Our findings indicate that 50-60 percent of...

We test whether firms react to changes in the wages and size of their competitors. We use a unique institutional feature of public procurement auctions in Brazil: the moment in which the auction ends is random. For close auctions, winner and runner-up are as good as randomly assigned. We first...

This paper uses seven standard market power indicators (price-cost margin, and six drawn upon the production approach) to estimate the effect market power on the rate of change of total factor productivity for a sample of formal manufacturing firms of Peru for the period 2002-2019. After...

Firms can increase the demand for their products and consolidate their market power not only by increasing user utility but also by decreasing non-user utility. In this paper, we examine this mechanism by considering the case of smartphones. In particular, Apple has faced criticism for allegedly...

A global monopoly supplier country of green goods which are essential for the provision of global environmental public goods optimally subsidizes the export of such goods in an interior contribution equilibrium. This is not counterbalanced by an incentive to improve the terms-of-trade, since any...

Der vorliegende Beitrag wendet die dynamische Wettbewerbstheorie von Wolfgang Kerber und anderen auf aktuelle Fragen der Wettbewerbspolitik an. Damit zeigt der Beitrag, dass dynamische Wettbewerbstheorien sehr wohl zu konkreten wettbewerbspolitischen Empfehlungen führen und einen wichtigen...

Labor economics often assumes that wages w are equal to the marginal revenue product of labor MRP L. However, recent literature has shown that firms' market power allows them to pay wages substantially below marginal productivity. The markdown (MRP L - w)/w is our preferred measure of firms'...

The diffusion of automation technology raises questions about the future of work, leading to calls for policy interventions. The ongoing debate centers on the decisions made by technology adopters. In this paper, I study supply-side adjustments and their role in shaping policy outcomes. I focus...

Can standard measures of industrial policy such as R&D subsidies or financial support for machine replacement be effective tools to reverse the current pattern of increasing market power and declining business dynamism? To answer this question we explore the effects of various industrial policy...

During the energy crisis in 2022, electricity prices in Germany soared to unprecedented levels. To explore the drivers of the high electricity prices, we develop an electricity dispatch model that simulates hourly equilibrium prices under the assumption of perfect competition. We then extend...

This paper provides a first empirical assessment of selected key indicators of the degree of competition in Austria in terms of industry concentration, firm-level markups and business dynamics. The analysis is based on firm-level data from 2008 to 2020 in collaboration with OECD Multiprod 2.0...
