We employ a Cournot model with interdependent demands to explore the interaction between demand and cost complementarities in mitigating upward pricing pressure, post-merger. The analysis reveals that even substantial increases in the HHI post-merger need not raise competitive concerns when output is redistributed from single-market to multi-market providers. Furthermore, the numerical simulations indicate that there is a wide range of demand and cost complementarity parameters over which even monopolization of the market would not be expected to result in higher prices. These findings may constructively inform merger policy and provide useful context for application of the DOJ/FTC horizontal merger guidelines in an increasingly digitized (network) economy.

Method Approach

Ketak handicraft is one of any other superior handicraft in Lombok Tengah Regency, as one of any other revenue generator for Lombok Tengah regency and to increase the prosperity of people in this industry, it is needed to find out the ways and strategies to improve the performance of this business. This research was categorized as a descriptive research which used case method approach, it was aimed to find out the position of ketak handicraft among handicraft industry in Lombok Tengah based on recent performance and to identify alternative strategies which can be chosen in order to improve the performance of this industry. In order to find out the position of ketak handicraft business, it was used BCG Agam analysis and based on this position the strategy for improving this business was selected based on this analysis, the position of third business was in the stars position, where alternative strategies that can be chosen were: (a) development of the existing product (market expansion for the existing product); (b) diversification; (c) horizontal merger. Suggestion recommended was to apply one of these strategies based on analysis that had been conducted.

AbstractWe revisit the linear Cournot model with uncertain demand that is studied in Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) and provide sufficient conditions for equilibrium uniqueness that complement the existing results. We show that if the distribution of the demand intercept has the decreasing mean residual demand (DMRD) or the increasing generalized failure rate (IGFR) property, then uniqueness of equilibrium is guaranteed. The DMRD condition implies log-concavity of the expected profits per unit of output without additional assumptions on the existence or the shape of the density of the demand intercept and, hence, answers in the affirmative the conjecture of Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) that such conditions may not be necessary.

Given a continuous Cournot map F(x,y)=(f2(y),f1(x)) defined from I2=[0,1]×[0,1] into itself, we give a full description of its ω-limit sets with non-empty interior. Additionally, we present some partial results for the empty interior case. The distribution of the ω-limits with non-empty interior gives information about the dynamics and the possible outputs of each firm in a Cournot model. We present some economic models to illustrate, with examples, the type of ω-limits that appear.

AbstractOn the occasion of the 10th anniversary of the 2010 U.S. Horizontal Merger Guidelines, this article provides an overview of the state of economic analysis of unilateral effects in mergers with differentiated products. Drawing on our experience with merger enforcement in Europe, we discuss both static and dynamic competition, with a special emphasis on the calibration of competitive effects. We also discuss the role of market shares and structural presumptions in differentiated product markets.
