This chapter proposes three different definitions for the market power in the antitrust case, such as dynamic monopoly power, static monopoly power and market power.

The chapter presents simple economic models to analyse which definition of the three market powers is consistent with predatory pricing or tying.

The prerequisite market power is simply market power in the predatory pricing case or static monopoly power in the tying case.

Dynamic monopoly power defined as the market power from an antitrust perspective by the Antitrust Modernization Commission should not be the prerequisite market power in the case of the abuse of dominance or the violation of Section 2 of the Sherman Act.

A possession of substantial market power or monopoly power is typically understood as a prerequisite in abuse of dominance in Korea and EU or violation of Section 2 of the Sherman Act in the United States. However, the antitrust law does not clearly indicate the meaning of market power or monopoly power. This chapter proposes three different definitions for the market power in the antitrust case and analyses which definition of the three market powers is consistent with predatory pricing or tying.

To address the various irregularities that occurred during the development of China’s electricity market, particularly the issue of collusive pricing between upstream and downstream firms.

This study constructs a tripartite evolutionary game model involving government regulators, grid operators and power producers to address electricity market pricing chaos. By analyzing the stable strategies within each subject’s evolutionary game, adjustments to the relevant parameters are made to achieve a stable state of strategy selection.

The findings of this study indicate the following: (1) Enhancing the government’s rewards and punishments, increasing speculation and rent-seeking costs for grid operators and modifying tariff sales revenue can promote the integrity of grid operators. (2) Establishing reasonable incentives and penalties can effectively mitigate rent-seeking behaviors resulting from collusive pricing in the power industry. (3) Strengthening the accountability of higher authorities to government regulators and adjusting incentives for grid operators to comply and generators to refrain from rent-seeking behavior can increase the likelihood of rigorous inspections by government regulators.

This study elucidates the impact of factors such as the cost of speculation and sales revenue of grid operators, the cost of rent-seeking by power producers and the strength of rewards and punishments by government departments on the power sector. Adjusting these factors can significantly influence the stability of the three-party evolutionary game, providing valuable insights into the regulatory mechanisms of the power industry.

Over the past three decades, financial deregulation and various reforms have significantly transformed the competitive environment for banks in Indonesia. These changes have introduced new challenges for banks to retain their market power and ensure their survival. In light of this, the article aims to assess the current levels of market power held by Indonesian banks and explore the factors that influence it.

The paper measured the degree of market power and identified its impacting factors for 22 listed commercial banks using the Adjusted Lerner Index (ALI) and appropriate regression technique over a period of 2011–2023.

The empirical findings reveal that banks in Indonesia enjoy high market power, and factors such as capitalization, diversification, operational inefficiency, asset quality and GDP growth rate significantly impact banks’ market power. Additionally, the findings contradict the structure-conduct-performance paradigm, which advocates that a concentrated banking system impairs competition.

The study suggests that regulatory authorities should closely monitor the market power levels and promote strategies to enhance competition within the banking sector. Additionally, banks should prioritize implementing measures to reduce operational costs and improve the quality of assets.

This research represents one of the early attempts to gauge the market power of publicly listed conventional commercial banks in Indonesia by employing the Adjusted Lerner Index. Additionally, it introduces “technology adoption” as a novel variable to the analysis alongside other established variables.

Complaints about lower agricultural farm-gate price and higher consumer price have emerged in China in recent years. The large gap between dairy farm-gate price and consumer price gives rise to worries that China's dairy industry is characterized by strong degree of oligopoly. The purpose of this paper is to take the dairy processing industry as an epitome of China's food industry, and use a new approach to investigate whether it is oligopolistic and/or oligopsonistic.

Based on a new proposed Primal-Dual Solow Residual model, the authors first test the hypothesis that there are significant oligopoly and oligopsony powers in China's dairy sector, and the latter is stronger. The authors then turn to measure these two kinds of market power using regressions of the model.

The estimation results show that firms in the sector have both strong oligopoly and oligopsony power, but the latter is stronger than the former. Meanwhile, with the continuous reinforcement of competition in China's dairy sector, market power in both the upstream and downstream has decreased slightly.

This paper is the first to simultaneously test oligopoly and oligopsony power in China's dairy sector. The empirical results explicitly imply that more attention should be paid to the raw milk purchase market.

The purpose of this paper is to investigate the role of market power and returns to scale in the determination of farm-value share.

This paper utilizes the equilibrium displacement model to investigate the role of market power and returns to scale in the determination of farm-value share. Contrary to the current literature, the paper incorporates oligopoly power, oligopsony power and non-constant return to scale into one generalized model, which systematically enables us investigate the impacts of market power on the determination and changes of farm-value share.

The results imply that market power as well as non-constant returns to scale is central to the understanding of farm-value share. These, in turn, indicate that ignoring the impacts of market power and degree of return to scale may overestimate or underestimate the impacts of exogenous shocks on changes in farm-value share.

Thus, to the best of the authors’ knowledge, no literature has examined the co-existence of oligopsony power, oligopoly power as well as non-constant return to scale in farm-value share determination. This paper therefore tries to fill this gap.

The purpose of this paper is to introduce a prospective market monitoring system (MMS) for surveillance of Indian power market using a set of new market monitoring indices.

It is necessary for the system regulators and policy makers to identify the potential market power and find ways to mitigate them to improve the market efficiency. The simple way to curb market power is the capping of bidding price to several times the average price of electricity. However, this approach is not ideal as it could mask the real market trading situation. The best way for the regulator is to identify which particular generators are exercising market power and deal with them individually.

Identification of major activities under MMS and effectiveness of new market indices have been established through quantitative analysis.

The MMS will provide in‐time warning signals and identify the suppliers taking maximum unfair advantage which needs intense scrutiny by monitoring unit.

Very few works have discussed detail market monitoring issues for the markets those are in their early stages of development like Indian electricity market. Indian Energy Exchange as a first power exchange in India became operative from June 2008, therefore, it is very important to develop an effective MMS.

The purpose of this paper is to examine the relationship between manufacturer profit rate and large retailer market share for five matched retailer‐manufacturer groupings.

Basic structure‐performance modeling is used to relate manufacturer return on assets to large retail market share and a group of control variables. Internal Revenue Service (IRS) Corporate Statistics of Income size class data provide a sample that covers the full range of firm sizes from the smallest to largest firms in the USA.

Large retail share negatively impacts small manufacturer rate of return for shopping goods, while in convenience good markets large retail share has no impact on manufacturer return.

Shopping goods retailers have opportunities to gain market power from expertise in merchandising, sales assistance, and product expertise. Strong private brands may offer leverage for convenience good retailers in negotiations with national brand manufacturers.

The paper examines the impact of retail channel power on small, medium, and large size manufacturing firms in five retailer/manufacturer categories over a period of extensive change in retail concentration.

Based on the widely held view that influence is exercised power, and in light of the suitability of power theory to studies of marketing's relative influence within the firm, this paper seeks to explore marketing's level of influence from a power perspective. The paper proposes and empirically tests a model in which the marketing function's four key types of power (bureaucratic power, critical contingencies power, network power, and psychological power) act as antecedents to marketing's influence within the firm. The model also aims to consider the contingency effect of market turbulence.

The study employs data drawn from a sample of senior managers in medium and large manufacturing firms. The model is tested using hierarchical ordinary least squares regression analysis.

The findings provide support for a link between all types of power and marketing's influence, with the exception of psychological power. Market turbulence is also found to strengthen the positive link between marketing's critical contingencies power and marketing's level of influence.

The study identifies and discusses power mechanisms that may be employed by marketing subunits to maintain or strengthen their influence within the firm.

Empirical evidence has shown that strong marketing functions are still needed, yet are slowly disappearing. This study approaches the question of how marketing departments can protect or regain their influence by adopting a power perspective. The findings suggest that marketing departments can tap into different types of power to further their influence. The study discusses the key theoretical and managerial implications and proposes some directions for future research.

The emerging consumer-dominant logic of marketing captures consumers’ active and primary role in a range of mainstream marketing processes such as branding, product development and sales. However, consumers’ active role in driving pro-social behaviour change has not yet received close attention. The purpose of this paper is to introduce and explore consumer dominance in social marketing. The authors propose a definition of consumer-dominant social marketing (CDSM) and explicate five key elements which underpin the phenomenon.

This conceptual study offers an analysis informed by exemplars with significant representations of consumer-dominant pro-social behaviours and projects. The methodological approach is characterised as “envisioning conceptualisation”, which is explained in terms of MacInnis’ (2011) framework for conceptual approaches in marketing.

As a phenomenon, CDSM operationalises the following elements: power, agency, resources, value and responsibility. The authors demonstrate how these elements are interconnected and define their meaning, significance and implications in the context of social marketing and pro-social behaviour change. The authors also identify this new form of social marketing as existing on a continuum depending on the level of involvement or dominance of the consumer and of social marketers; at one end of this continuum, exclusive CDSM is entirely consumer-driven and does not engage with businesses or organisations, while on the other end, inclusive CDSM encompasses partnership with external stakeholders to achieve pro-social behaviour change.

The existence of inclusive and exclusive CDSM points towards an intricate power balance between consumers, mainstream social marketers and businesses. While this study identifies and explains this substantial distinction, it is an important task for future research to systematise the relationship and explore the optimal balance between consumer activism and involvement of formalised organisations such as charities and businesses in pro-social behaviour change projects.

The study provides social marketing professionals with an understanding of the benefits of harnessing consumer empowerment to enhance the impact of social marketing interventions.

The study makes a theoretical contribution by introducing, defining and explicating consumer dominance as a substantive area of social marketing.
