This study investigates the impact of market structure on the performance of banks in Pakistan. It explicitly tests two competing hypotheses: the Structure-Conduct-Performance paradigm and the Efficient Structure Hypothesis, providing insights into whether profitability stems from market...

This study examines the extent to which market size disparity across franchises - measured as the coefficient of variation of MSA populations - moderates the effectiveness of competitive balance interventions (CBIs) in Major League Baseball (MLB), the National Football League (NFL), the National...

This paper extends the CES model of monopolistic competition to the case where varieties are both horizontally and vertically differentiated. A distinctive feature of our model is the presence of a network externality, which operates through the number of varieties available at each quality...

This paper examines the "right" geographic definition of relevant markets by analyzing how excise tax pass-through varies with local competition in the retail gasoline market of a large metropolitan city. Using a natural experiment from three unanticipated and exogenous fuel tax hikes and...

We study competition between a welfare-maximizing public platform and a profit-maximizing private platform in a two-sided payment market. We characterize the public platform's optimal pricing and show that it balances the benefits of increased competition against the welfare costs of network...

Palau’s financial system faces structural challenges that inhibit effective financial intermediation, mobilization of domestic savings, and payment system efficiency. The authorities have been striving to address these challenges through digital initiatives. While these initiatives are...

This paper examines whether the SEC's mandate for central clearing of U.S. Treasury repo transactions could enable all-to-all trading and support the development of a standardized term repo market. By mitigating counterparty risk through central clearing, cash lenders may become more willing to...

This paper extends the CES model of monopolistic competition to the case where varieties are both horizontally and vertically differentiated. A distinctive feature of our model is the presence of a network externality, which operates through the number of varieties available at each quality...

The present paper utilizes AnaCredit loan-level data to examine the impact of regional loan market structure on lending rates. The analysis focuses on newly issued loans to small non-financial corporations in the euro area during the monetary policy tightening phase of 2022 and 2023. The...

We study how inflation varies across regions with different income levels and the role of retailer market structure. Using NielsenIQ Retail Scanner and Business Dynamics Statistics data, we document new stylized facts of spatial heterogeneity in food inflation and retailer market structure. From...

In many industries, platforms compete with incumbents that are open to all consumers, whereas platforms require user affiliation. Consequently, platforms face two layers of competition: for the market, to attract users, and in the market, to compete with incumbents. We develop a dynamic model...

We develop a data-driven procedure to identify which correlations in high-dimensional dynamic systems should be time-varying, constant, or zero. The method integrates a vine-based multivariate partial correlation model with sequential penalized estimation. Applied to 50 US equities and...

Online platforms have evolved into powerful programmable architectures that enable heterogeneous groups of autonomous but interdependent users to interact. Based on a stratified sample of 1,380 companies from a newly developed enterprise survey in Austria, the analysis aims to reduce the lack of...

This paper shows that in an economy where distortions prevent firms from using their profit-maximizing amounts of capital and labor, removing these distortions can generate both an efficiency gain and a higher aggregate labor share. We use firm-level data on Chinese manufacturing, mining, and...

This paper examines the welfare implications of priority service in a frictional search environment with heterogeneous outside options. Priority search facilitates expedited matching with public options in the market by charging a service premium. Our main analysis demonstrates that a...

The rapid advancement of artificial intelligence (AI) relies on a complex supply chain comprising five key layers: hardware, cloud infrastructure, training data, foundation models and AI applications. This paper examines the market structure of each layer and highlights the economic forces...

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...

El hambre y la desnutrición siguen siendo desafíos de desarrollo críticos en América Central. Desde 2020, han aumentado las tasas de inseguridad alimentaria moderada y grave en toda la región, mientras que los indicadores clave relativos a la nutrición en la primera infancia siguen siendo...

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....
