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...

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...

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 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 paper describes the organization of the market for trading Government of Canada (GoC) bonds. We outline the role of investment dealers in intermediating trading, distributing GoC securities and providing liquidity across the yield curve. We describe the key features of GoC bond trading and...

In the German pharmacy market, strictly regulated prescription (Rx) drug prices coexist with free pricing for over-the-counter (OTC) drugs. This paper investigates the extent of market power in the non-prescription segment (OTC drugs and non-pharmaceuticals) and explores the role of Rx drugs in...

Using Wine Spectator's Top 100 lists for 1988-2025, this note applies Bai-Perron structural break tests to regional and country shares and identifies three distinct periods: 1988-1997, 1998-2015, and 2016-2025. Real prices decline across phases, with the sharpest drop in the most recent period,...

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 article examines U.S. Treasury securities market functioning from the global financial crisis (GFC) through the Covid-19 pandemic given the ensuing market developments and associated policy responses. We describe the factors that have affected intermediaries, including regulatory changes,...

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...

We develop a macroeconomic agent-based model to study the role of demand and supply factors in determining inflation dynamics. Local interactions of heterogeneous firms and households in the labor and goods markets characterize the model. Asymmetric information implies that firm selection is...

State governments provide grants to students to subsidize college attendance. In response, colleges can adjust their tuition, aid policies, and admission standards, affecting equilibrium enrollment and pass-through of aid to students. To quantify demand- and supply-side responses, I develop a...

We study the standard reputation model with a long-run (LR) player facing a sequence of short-run (SR) opponents, with one difference: the SR players are uncertain about the monitoring structure, while the LR player knows it. We construct examples where the standard reputation result breaks...

This article examines the price effects of gasoline stations following a retail merger in 2022. Using detailed station-level price data from 2020 to 2024, the analysis shows that fuel prices increase at both merging stations and their competitors, but with regional differences. These regional...

This study aims to investigate the impact of the market structure and efficiency on firm performance in the meat and milk processing industry in Poland, Czechia, and Slovakia. Using stochastic frontier analysis and a profitability regression model applied to data from 2015 to 2021, the results...

We study the welfare effects of a merger between ad-funded platforms facing elastic consumer demand. We show that advertising fees as well as quality investment levels by the platforms fall post-merger. Interestingly, despite the lower advertising fees, advertisers may be worse off when their...

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....

Non-bank financial institutions, such as principal-trading firms and hedge funds, increasingly compete with bank-owned dealers in fixed-income markets. Some market participants worry that if non-bank financial institutions push out established bank dealers, liquidity will become unreliable...

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...

Heterogeneous interconnections, which link regulated electricity markets to liberalised ones, are becoming increasingly important. Several such interconnections are set to be established in the near future especially between European and North African countries (e.g., Tunisia-Italy,...

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...

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...
