We analyze a sample of consumer-electronics products sold by the US NewEgg online-retailer to study the impact of Price Matching Guarantees (PMGs) policies on prices. By applying aDifference-in-Differences approach,we find that prices of the policy-adopting retailer increase by 4.7% during the...

This paper explores and quantifies the importance of parent brand state dependence to forward looking pricing outcomes in the area of umbrella branding and multi-product firms. We show through numerical simulations that loyalty (inertia) to the parent brand can decrease prices and reduce...

Looking at a large number of markets, I find that (i) prices and variety are higher when there are two competing supermarkets than in those with a single store and (ii) the two effects are positively correlated. This pattern persists after controlling for differences across markets in a variety...

Artificial Intelligence (AI) automates human decisions. Algorithmic pricing, a form of AI, sets prices by a computer. It is now common currency in ride-hailing, travel, drugs, gasoline, online goods---And great price variability characterizes all those settings. However, little is known about...

Price comparison websites, where consumers can compare prices at a search cost that is close to zero, have become increasingly common around the world. Using daily information on prices, click-throughs, and the number of retailers for a sample of consumer electronics and durable goods over a...

How should firms optimally choose prices and promotional strategies and how should they position their products when consumers are "relative thinkers"? We provide answers in a model that extends the seminal contributions of Varian (1980) and Narasimhan (1988) and derive both managerial...

This paper presents an empirical study of the impact of Wal-Mart supercenter conversion (i.e., expansion of traditional discount-format stores by adding new departments) on consumer shopping behaviors. By using a difference-in-difference estimator and a joint model of store visits and...

This paper studies the consequence of an imprecise recall of the price by the consumers in the Bertrand price competition model for a homogeneous good. It is shown that firms can exploit this weakness and charge prices above the competitive price. This markup increases for rougher recall of the...

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

Improving public transport infrastructure changes local market conditions. In this paper, I examine the impact of the construction and operation of "Metrobus", Mexico City's Bus Rapid Transit (BRT) system on consumer prices in chain stores, street vendors, and small family-owned (mom and pop)...
