Data, Product Targeting and Competition
Abstract
We analyze how access to data affects competition and consumer surplus in amodel where more data allows firms to offer products that are better targeted
to consumer preferences and at the same time to price discriminate more
effectively. We find that consumer surplus in a monopoly market is highest for
an intermediate level of data access, while it is increasing in available data
when firms compete. The effect of data on competition is asymmetric:
Competition becomes fiercer if the more poorly informed firm gets better
information, but softens when the better informed firm improves its
information. Firm's preferred choice of information is an outcome where they
are strongly differentiated by information quality. This preference limits the
possibility to create an informational level playing field via data sharing or
data brokers, and explains why total surplus may drop following entry. If an
entrant can use data gathered in one market in another market, entry does not
necessarily improve overall consumer surplus, since it enhances the entrant's
ability to price discriminate in the other market.
Broadband Deployment in Equilibrium: Is Competition the Solution to the Digital Divide?
Abstract
Broadband access has become a near necessity, yet many U.S. households remain without access or significant choice among Internet service providers. This paper examines whether competition between broadband providers increases the availability and quality of broadband, as well as the effects of policies that have been proposed to ameliorate the digital divide. Combining data from a survey of Seattle households’ broadband subscriptions and broadband deployment data from the FCC, I estimate a structural model of Seattle’s broadband market, which allows me to quantify the effect of competition on broadband availability, quality, and price in equilibrium. I find that, of recent policies proposed to address the digital divide, a demand-side subsidy program increasing broadband affordability for low-income households is significantly more cost effective than a supply-side policy that subsidizes increased broadband deployment. Additionally, I find evidence that providers’ incentive to increase quality is weaker under competition, however, the benefits of competition to consumers, in terms of increased product choice and lower prices, are substantial.Market Power and Spatial Price Discrimination in the Liquefied Natural Gas Industry
Abstract
The liquefied natural gas (LNG) industry is characterized by systematic inter-regional price differentials, raising the question of whether sellers price discriminate. This paper measures market power in the LNG spot market and studies how market power influences pricing, trade and welfare. I develop a novel method for inferring market conduct that utilizes information on sellers' pricing and quantity decisions across multiple geographically segmented markets. My test for market conduct is based on the observation that sellers exercising market power engage in third-degree price discrimination, whereas sellers behaving competitively do not. Using data from 2006 to 2017 on spot market trade flows, spot prices, shipping costs and seller capacities, I estimate a structural model of LNG trade and pricing that incorporates spatial differentiation, capacity constraints and trade frictions and flexibly nests different models of seller market power. I find that seller decisions are consistent with a Cournot model and unlikely to be generated by a competitive model. The total deadweight loss from market power is estimated to be USD 12 billion, or about 4.5% of total revenue. I find that market power plays a key role in exacerbating inter-regional price differentials.Price Competition under Information (Dis)Advantage
Abstract
We examine the impact of asymmetric data access within a vertically integrated e-commerce platform. Using a unique daily panel, we find that both the platform owner and third-party sellers base pricing on past sales, but only the owner exploits competitors' sales data. We estimate a price competition model with heterogeneous seller learning. We find that (1) eliminating the owner's access to competitors' data increases social welfare by 0.33%, negatively impacting the owner through reduced first-party sales and (2) providing third-party sellers with equal access to competitors' data as the owner increases social welfare by 1.65%, benefiting the owner through increased referral fees and yielding a Pareto improvement.JEL Classifications
