The decentralized nature of blockchain markets has given rise to a complex and highly heterogeneous market structure, gaining increasing importance as traditional and decentralized (DeFi) finance become more interconnected. This paper introduces the DeFi intermediation chain and provides...

The trade war between the United States and China since 2008 has opened strategic opportunities to increase the economic market in ASEAN countries. This research aims to answer whether the trade war led to an oligopoly or a systemic market structure as a strategy for increasing demands,...

We study firms' strategic interactions when each firm may own multiple production technologies, each with its own marginal cost and capacity. Increasing industry concentration by reallocating non-efficient capacity to the largest and most efficient firm can decrease market prices as it...

This paper extends the Cournot duopoly model by allowing the government to impose firm-dependent specific taxes or subsidies while keeping the budget balanced. It considers two possible government goals: maximizing the social surplus and maximizing the consumer surplus. It shows that, with...

I study sequential contests where the efforts of earlier players may be disclosed to later players by nature or by design. The model has many applications, including rent seeking, R&D, oligopoly, public goods provision, and tragedy of the commons. I show that information about other players'...

Purpose of the article: A correct understanding of mechanisms governing the market is crucial for proper functioning of the labour market. The market structure phenomenon, so far most frequently described in the imperfect competition theory as a bilateral monopoly, occupies a unique position in...

This paper adds to the literature on transboundary pollution by considering pollution related to both production and consumption activities. In particular, we consider a symmetric strategic two firm-two country game model with bilateral trade and transboundary pollution to analyze the effects of...

Surveys of cartel proceedings reveal that illegal cartels usually (1) attempt to minimize the risk of detection, (2) achieve merely imperfect levels of collusion, (3) compete against some fringe firms, and (4) adjust to market entries and exits. By contrast, existing oligopoly models of...

We develop a two-stage game in which competing airlines first choose the networks of markets to serve in the first stage before competing in price in the second stage. Spillovers in entry decisions across markets are allowed, which accrue on the demand, marginal cost, and fixed cost sides. We...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

We have built and investigated analytically and numerically a differential game model of Cournot oligopoly with consideration of pollution, network structure, and continuous updating. Up to this time, games with network structure and continuous updating were considered separately. We analyzed...

A major section of the existing literature on strategic trade policy, following a partial equilibrium framework, observed that imposition of tariff by the domestic country leads to a rise in their wage level. Analysis on the impact of strategic trade policy intervention (tariff) on wages and...

We study the propensity of independent algorithms to collude in repeated Cournot duopoly games. Specifically, we investigate the predictive power of different oligopoly and bargaining solutions regarding the effect of asymmetry between firms. We find that both consumers and firms can benefit...

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 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...

While an influential body of economic literature shows that allowing for communication between firms increases collusion in oligopolies, so far we have only anecdotal evidence on the precise communication content that helps firms to coordinate their behavior. In this paper, we conduct a...

This paper analyses the impact of transparency regulations on Super 95 and Diesel prices in Austria, France, and Germany to shed new light on the price effects of regulatory policies. To identify the effects of regulation, we use publicly available data from January 2005 to the end of December...

I derive a model-based equation relating pass-through to buyer size and estimate it on the micro transaction level data for Colombia. I find that after an exchange rate shock, sellers connected to larger buyers face more moderate changes in their prices in the seller currency (i.e., lower...
