Widespread market imperfections in agricultural value chains raise the possibility that regulatory interventions may enhance efficiency and farmers' welfare. We develop a structural model of agricultural value chains and estimate it using rich data from Costa Rica's coffee sector to evaluate...

This manuscript presents a detailed summary and reassessment of the 1941 final report of the Temporary National Economic Committee (TNEC). We portion the manuscript into four major parts: background, major themes, assessment of the report, and additional analysis and reflection. In the first...

Economic super-powers are racing to control critical minerals in developing economies fueling conflict, environmental damage and poverty. In this paper, we first explore what could well constitute a new “critical minerals curse”. We then highlight the dualism of institutions required for...

This paper studies the relationship between market concentration and aggregate productivity when firmlevel demand emerges from past marketing investments. Granular firms may invest in demand both to complement their productivity and to amplify market power-this second force can create persistent...

In this paper, we study the impact of monopsony power on the gender wage differentials at various parts of the wage distribution from 2019 to 2022. We are measuring hiring labour market concentration by constructing the HHI on the basis of online job advertisement data from Germany.The wages and...

Starting from the superstar firm hypothesis of Autor et al. (2020), the paper conceptually analyses the regional industrial market power-induced effect on profit shares elaborating on the role of space. Our idea is that an industrial market power-induced effect exists, but this is heterogeneous...

Numerous studies have explored the possible causes of global carbon emissions and climate change; however, the impact of export diversification and concentration on these emissions is a less examined topic in literature. This study investigates the effects of export diversification and...

The changes in market structures in post-socialist economies have led to a significant increase in interest in the dynamics of corporate concentration and its broader socio-economic impacts. This study aimed to assess Hungary's food industry over a 30-year period (1993-2022), with a primary...

We consider an overlapping generations version of a model suggested by Fargione, Lehmann and Polasky that allows us to show, by means of simulations, that randomness of the rate of return on capital, combined with inheritance of capital and consumption being a concave function of wealth may lead...

This paper investigates real earnings management (REM) practices in public non-financial companies listed on the Warsaw Stock Exchange (WSE) from 2014 to 2023, focusing on sectoral differences and the influence of market competition. REM, defined as deviations from normal business operations...

In 1962, Spain implemented significant banking law changes to boost competition. This study investigates their impact on provincial banking concentration from 1964 to 1975, utilising novel provincial-level private bank balance sheet data and including savings banks. Results show a substantial...

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...

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...

Given the changing landscape of fuel retailing, this study explores the impact of spatial competition and market concentration on diesel prices in Germany. The question of how population density and gas station density, i.e. the equilibrium pattern of locations of firms, are related is examined....

Policymakers face a dilemma in determining the optimal approach to regulating highly concentrated markets, especially in the context of digital government initiatives in healthcare. The current study investigates whether vendor market concentration facilitates or impedes efficiency in health...

This paper studies concentration and market power in Chile and Colombia and the role that globalization and automation have had in shaping these two phenomena. Using panels of firm surveys, we compute firm-level markups and industry-level concentration measures. Applying a difference in...

With the rise of environmental awareness, stakeholders are increasingly insisting on a sustainable corporate strategy. This study examines the impact of supply chain concentration on green innovation in Chinese manufacturing firms listed on the A-share market from 2011 to 2022. The results show...

Antitrust policy aims to reduce market concentration and increase competition among firms. Contemporary antitrust is sensitive to both domestic and international considerations. Internationally, the market is dominated by the largest firms, raising questions about the competitiveness of domestic...

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....

Financial inclusion is an important enabler of economic development and aligns with several United Nations Sustainable Development Goals. In most sub-Saharan African countries, financial inclusion efforts take place in the presence of concentrated and bank-dominated systems. This study...

This paper derives a closed-form expression linking aggregate markups on im- ported inputs to concentration in a model of firm-to-firm trade with two-sided market power. Our theory extends standard oligopoly insights in two dimensions. First, it reveals that markups increase with exporter...

Concentrations with EU relevance, depending on their features, may fall under multiple legal regimes. EU/national merger control systems, antitrust rules, the Digital Markets Act, and the Foreign Subsidies Regulation impose (more or less) comprehensive jurisdictional, procedural and substantive...

Alongside the recent regulations addressing platforms and digital markets - the Digital Services Act (DSA) and the Digital Markets Act (DMA) - the European Union's (EU) European Media Freedom Act (EMFA) aims to safeguard media freedom and pluralism, two essential pillars of democracy. The EMFA...
