Federated Learning (FL) is an innovative technique that allows multiple firms to collaborate in training machine learning models while preserving data privacy. This is especially important in industries where data is sensitive or subject to regulations like the General Data Protection Regulation...

This paper provides a simple unified discrete-choice framework for analyzing differentiated duopolies. This framework nests models of horizontal and vertical differentiation, including standard textbook models (Hotelling and Shaked-Sutton). Contrary to these models, it also applies to economic...

Consumers increasingly value the environmental and social responsibility of the production processes used by firms, yet these processes often remain unobservable, even after consumption. In this paper, we develop a simple model to examine firms’ technology choices and subsequent price...

We present a simple model where, before competing in prices, firms announce which prices they intend to choose. Deviating from these announcements involves a cost. We show that sharing pricing intentions results in prices being set above their competitive levels. All equilibria result in prices...

This paper studies a class of two-player all-pay contests with externalities that encompass a general version of duopoly price competition. This all-pay contest formulation puts little restriction on production technologies, demand, and demand rationing. There are two types of possible...

Sales tax is generally not included in the advertised price quoted to consumers in the United States. In contrast, value added taxes (VAT) are embedded into the price in most other countries. This article investigates how the two different pricing structures and consumers' decision-making...

We develop models of markets with procrastinating consumers where competition operates - or is supposed to operate - both through the initial selection of providers and through the possibility of switching providers. As in other work, consumers fail to switch to better options after signing up...

This paper studies how selling constraints, which refer to the inability of firms to attend to all the buyers who want to inspect their products, affect the equilibrium price and social welfare. We show that the price that maximizes social welfare is greater than the marginal cost. This is...

One disputed topic in Organization and Management economics is how leadership and collusive agreements are set and maintained in industries where firms are characterised by similar technological opportunities and structures. This topic is particularly important to analyse online and digital...

In markets where sellers' marginal costs of production have a common component, they have informational advantage over buyers regarding those costs. This information asymmetry between sellers and buyers is especially relevant in markets where buyers have to uncover prices through costly search....

We develop a tractable model of competitive price cycles where prices are chosen alternatingly and consumers have heterogenous information. The model yields sharp empirical predictions about price patterns, impact of captive consumers and pass-through. Using rich station-level price data from...

Competition authorities impose substantial penalties on firms engaging in illegal pricefixing. We examine how basing cartel fines on either revenue, profit, or price overcharge influences cartel and market prices, as well as cartel incidence and stability. In an infinitely repeated Bertrand...

We investigate the impact of an environmental award in a Bertrand duopoly with green consumers considering a three-stage game. First, the regulator designs the environmental contest. Second, firms choose their green investments, and the winner of the contest is awarded. Third, firms compete in...

This paper considers a delegation game between one multi-input firm and one single-input firm engaging in Cournot competition in the downstream market. Both firms purchase a standard input from a core input supplier, and the multi-input firm also needs a supplementary input provided by an...

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...

Over the last decades, dynamic pricing has become increasingly popular. To solve pricing problems, however, is particularly challenging if the customers' and competitors' behavior are both strategic and unknown. Reinforcement Learning (RL) methods are promising for solving such dynamic problems...

This study constructs a model of exclusive-offer competition between two existing up-stream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the upstream firm is...

The objective of this work is to evaluate the effects of adopting technological innovation, non-technological innovation, and their complementarity on price competitiveness. This work employs a recursive bivariate probit model applied to microdata from 1897 firms in three Sub-Saharan countries:...
