This paper examines the relationship between labour market concentration and wage inequality using global survey data for the period 2006-2022. The results show that higher labour market concentration is associated with higher wage inequality, especially in the top half of the wage distribution....

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...

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...

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...

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...

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....

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...

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...

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...

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...

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 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...
