Estimation of market power and efficiency at firm level
In the context of a dynamic environment, we estimate the market power of US airlines in two city pairs by both allowing and disallowing corporate inefficiencies. In the context of a dynamic environment, we estimate the market power of US airlines in two city pairs. This chapter examines the relationship between market power and cost efficiency, the silent life hypothesis, and the two competing hypotheses of the, To measure the firm's market power, we use the Lerner index which is widely preferred in the literature. Specifically, we define the Lerner index of market power as follows: Firms with stronger market power exhibit higher cost efficiency, which contradicts the silent life hypothesis. I conduct these studies using new empirical techniques and detailed detailed datasets at the firm and household level. In the first chapter, co-authored with Shruti, Ref A: 662a7d089c434a11a872ff2d979fb B: DUBEEAP0000E C: 2024-04-25T15:55:52Z, Essay on Estimation of Market Power and Efficiency at Firm Level Mergers and Acquisitions.

The five. Purpose - The purpose of this article is to examine market power in the dairy industry in China. Specifically, we empirically analyze market power for different company sizes, regional and city locations. Design Methodology Approach - We estimate market power by controlling unobserved price heterogeneity. The econometric model was, following De Loecker et al. 2020, we characterize the evolution of market power based on data on listed companies in the Chinese economy. The increase is mainly caused by a few superstar companies. Moreover, we find strong evidence of an inverted U-shaped relationship between market power and investment. Firms with high market power may receive more favorable prices, and if the variation in market power with firm size is systematic, the estimate of cost efficiency may improve. be biased. Also, a modeling problem arises when multi-market and single-market firms compete locally in a market, because a firm-level model to estimate a cost function must,
