The effect of market power on allocative efficiency is one of the most important topics in industrial organization and has undergone rigorous investigation since the 1970s. However, empirical studies based on firm-level data are relatively rare, especially with regard to China's tobacco and food industries. Accordingly, this research measures market power and allocative efficiency loss (AEL) of the main tobacco and food industries in China with micro data at firm level. Subsequently, it conducts a comparative analysis on them.

This research applies the New Empirical Industrial Organization (NEIO) model, consisting of five pricing and demand simultaneous equations to measure market power, and the AEL model to measure AEL induced by market power. To match with the micro data at firm level, the study implements a change in the traditional NEIO model by abandoning the aggregating process.

Empirical results show that China's tobacco industry, among five sectors selected, has the largest market power and thus the highest degree of AEL, whereas other sectors have apparently smaller market power and lower levels of AEL. Comparative analysis demonstrates a coarse positive correlation between market power and AEL in the selected industries. In general, the results accord well with the existing empirical findings and the reality.

This study has some deficiencies. First, owing to the limitation of high-quality data, the sectors analyzed in this research are insufficient to sum up all the characteristics and rules of China's whole food industry. Second, this research only analyzes seller market power and leaves out buyer market power, which could be a direction for future research.

The relevant administrations should strictly limit the monopoly behaviors of enterprises and establish a favorable and competitive market environment, especially for the tobacco industry. This suggestion is precisely an important content of China's Supply-side Reform.

The research improves the NEIO model in that it can be estimated with micro data at firm level. To the best knowledge of the authors, very few empirical and comparative analyses exist on market power and AEL for China's tobacco and food manufacturers using micro data.

This paper aims to clear whether the monopoly structure of the internet industry has produced market power and discussed the welfare change of the internet industry monopoly.

By using new empirical industrial organization methods and taking the e-commerce market as an example, the authors measured market power and economies of scale of the internet platform companies.

Internet platform enterprises have formed scale economy, but it has not had market power, and the industry still maintains high levels of competition; also, the emergence of large enterprises may increase the welfare of consumers.

The conclusion of this paper clarified actual competition status of internet industry and provided a new foothold for regulation and ideas for the traditional industry to crack the Marshall Conflict.

Using the sample between 2005 and 2011, the purpose of this paper is to investigate the effect of a new fund entry on incumbents using the overlap measure in portfolio holdings.

Empirical methodology is used in this study.

The authors find that incumbents that have a higher overlap with the entrants underperform subsequently. Based on the characteristic-based approach of Daniel et al. (1997), the authors find that the characteristic selectivity component is negatively correlated with the overlap measure, and thereby the decline in performance is driven by the stock-picking ability. The authors also discuss the unobserved actions of incumbents using the approach proposed by Kacperczyk et al. (2008) and find that incumbent unobserved actions do not benefit mutual fund investors in China. Finally the authors find that investors respond to the supply-side competition between entrants and incumbents quickly. These findings help us understand the mutual fund completion in China.

The findings in this study can help scholars, industry experts and regulatory authorities to understand the effect of competition in Chinese mutual fund industry.

The purpose of this paper is to investigate market power in the Chinese pork supply chain. The authors aim to explain why a steady rise in prices is observed in the sector, apart from existing evidence on incomplete/asymmetric cost pass-through and concerns of growing concentration and consolidation in the sector.

This study uses a new empirical industrial organization model for both oligopoly and oligopsony power to measure the degree of market power exerted on consumers and hog farmers simultaneously.

By examining annual panel data across provinces in China, the authors find that both oligopoly and oligopsony powers exist in the pork supply chain. In particular, the authors determine that a higher degree of market power is found to influence prices paid to hog farmers than prices paid by pork consumers. Estimates of key elasticities in the Chinese pork supply chain are also updated based on the structural model estimation and the latest data.

Due to the lack of data at a more granular level of geography, the authors are only able to estimate market power by three major economic regions.

The findings provide useful information for future policy analyses of Chinese food markets. First, the pork-packing industry should be of great concern in terms of market power and its influence on consumers’ and farmers’ welfare. It is essential to take into consideration market power in the pork supply chain before making any public policy regarding the pork market. Furthermore, following economic theory and experience from developed countries, large meat packers will eventually vertically control hog farmers given their stronger oligopsony power over the upstream. Vertical integration may be the next important issue in terms of food market competition. Finally, the results may also draw the government’s attention to investigating market competition in all major food markets.

The empirical evidence draws attention to the issue of food market competition in one of the largest and most important meat-packing markets in China. The authors hope to encourage further discussions on pork and hog market regulations and related public policies.

The main objective of this paper is to propose a model that allows the detection of the competitive pattern of the Spanish loans market between 1992 and 1996.

In order to achieve this objective, the paper estimates, following the New Empirical Industrial Organization paradigm, a conjectural variation model for the strategic marketing dimension of price. The model proposed allows the measurement of strategic group‐level rivalry while simultaneously considering demand, costs, and profit specifications for each bank.

The findings evidence a high degree of competition between the firms within the same strategic group. Further, the demand for loans of a firm has a positive (negative) relationship with the rivals' price (own price), with the own branch network (rivals' branch network), and with the economic activity in the regions where firm operates.

The major limitation of this research could become from the necessity to operate with detailed information that the authors try to overcome using proxies of several non‐available variables.

The model proposed herein represents a contribution to previous works and also provides more information about banking competition in the sense that it estimates price competition between firms within three strategic groups.

The purpose of this paper is to examine the competitive conditions and market power of Islamic banks in Indonesia for the period of 2006-2013.

Using samples of 27 Islamic banks, the study uses a variety of structural and non-structural measures related to the traditional approach and the new empirical approach of the industrial organization. The methodology is based on a set of measures of the competition and market power. The first measures, concentration ratios and Herfindahl–Hirschman index, are to determine the competitiveness level, while the second measures of Panzar–Rosse H-statistic and Lerner index are to examine the market power of Islamic banks in Indonesia.

The finding of this study has confirmed the situation of Islamic banking industry in Indonesia which is operated in a higher degree of market power which leads to a less competitive market. Islamic banks earn their revenues under monopolistic competition over the tested period. This study has also found a negative but insignificant relationship between concentration and competition which shows that in the past few years, the market power for leading firms in Indonesia Islamic banking industry has reduced.

The paper is a very useful source of information that may provide relevant guidelines in guiding the future development of competition of Islamic Banking industry. In addition, the paper provides relevant guidelines for improving competitiveness of Islamic banks.

This study combines two approaches for bank competition measurement and bank market powers measurement which can provide more robust findings. To the best of the authors’ knowledge, the study on Islamic banking competitiveness level and market power is very limited, especially in the case of Indonesia. Therefore, this study could contribute significantly toward the literature of the related field.

The present study assesses the commercial bank profit efficiency and its relationship to banking sector competition in a rapidly growing emerging economy, India from 2009 to 2019 using stochastic frontier analysis (SFA).

Lerner indices, conventional and efficiency-adjusted, quantify competition. Two SFA models are employed to calculate alternative profit efficiency (inefficiency) scores: the two-step time-decay approach proposed by Battese and Coelli (1992) and the recently developed single-step pairwise difference estimator (PDE) by Belotti and Ilardi (2018). In the first step of the BC92 framework, profit inefficiency is calculated, and in the second step, Tobit and Fractional Regression Model (FRM) are utilized to evaluate profit inefficiency correlates. PDE concurrently solves the frontier and inefficiency equations using the maximum likelihood process.

The results suggest that foreign banks are less profit efficient than domestic equivalents, supporting the “home-field advantage” hypothesis in India. Further, increasing competition drives bank managers to make riskier lending and investment choices, decreasing bank profit efficiency. However, this effect varies depending on bank ownership and size.

Literature on the competition bank efficiency link is conspicuously scant, with a focus on technical and cost efficiency. Less is known regarding the influence of competition on bank profit efficiency. The article is one of the first to examine commercial bank profit efficiency and its relationship to banking sector competition. Additionally, the study work represents one of the first applications of the FRM presented by Papke and Wooldridge (1996) and the PDE provided by Belotti and Ilardi (2018).

This study aims to investigate both market concentration and bank competition of banking across six emerging Asian countries (e.g., Bangladesh, Indonesia, India, Philippines, Malaysia, and Vietnam) over pre and post the 2008 global financial crisis. The conduct parameter approach following the framework suggested by Uchida and Tsutsui (2005) is used to estimate bank competition in these countries. The study employs both seemingly unrelated regression (SUR) and three-stage least squares (3SLS) to estimate simultaneously the system of equations in our model. Generally we find a negative association between market concentration and bank competition across most of the countries in the study suggesting that banks in concentrated markets collude to generate higher profits. Monopolistic competition was the best description of competitive structure of banking across the majority of countries investigated by this study. The study fills the gap in the banking literature by investigating bank competition, concentration, and their relationship across emerging Asian economies over the 2008 global financial crisis. Moreover, several policy implications for banking industry are suggested.

The paper measures the degree of bank competition in Indian banking over the period 1996–2016. Using bank-level annual data, we revisit the case of banking competitiveness during the prefinancial and postfinancial crisis and examine whether the global financial crisis alters the level of bank competition in India. Additionally, this paper addresses the misspecification issues associated with the widely used Panzar–Rosse model in Indian banking context.

We apply Panzar and Rosse (1987) H-statistic and evaluate the degree of bank competition by estimating the extent to which changes in input prices are reflected in revenues earned by banks. Subsequently, we link this measure of competitiveness to a number of structural indicators (HHI and CRn) to examine the structure-conduct-performance hypothesis, which assumes that a concentrated banking system can impair competition. The simple panel regression model was used to handle the empirical estimations.

findings reveal that the Indian banking system operates under competitive conditions and earns revenues as if under the monopolistic competition. We also find evidence that Indian banks are competitive, even under a concentrated market structure. This observation runs, in contrary, to the prediction of the structure–conduct–performance hypothesis. The findings also indicate the differences in the estimated H-statistic value after considering the misspecifications of the P–R model.

From policy perspectives, policymakers should focus more on maintaining an optimal level of bank competition by mitigating entry restrictions, exercising less consolidation and withdrawing overregulation from banking activities. A competitive banking industry ensures both efficiency and stability.

A competitive banking sector by lowering interest rates margin provides easier access to finance to both households and small and medium enterprises (SMEs).

This is the only study that addresses the misspecification of the P–R model while assessing competition in Indian banking and provides a thorough understanding of the role of concentration on bank competition.
