I explore the competitive effects of on-net/off-net differentiation in a market with two asymmetric networks by combining the literature on on-net/off-net differentiation with research on costly consumer search in an agent-based simulation model. All consumers in the market are subscribed to one...

Despite the existence of two vast literatures, very little is known about the potential differences or interactions between search and switching costs. This paper demonstrates the benefits of examining the two frictions in unison. First, the paper shows how subtle distinctions between the two...

One of the most significant and robust characteristics of decision making is persistence. An example of this is brand loyalty -- the repeat purchase of new products of the same brand. This paper attempts to show that previous explanations of this phenomenon (switching costs, habit and unobserved...

How do voters allocate costly attention to alternative political issues? And how does selective ignorance of voters interact with policy design by politicians? We address these questions by developing a model of electoral competition with rationally inattentive voters. Rational inattention...

We study a consumer non-sequential search oligopoly model with search cost heterogeneity. We first prove that an equilibrium in mixed strategies always exists. We then examine the nonparametric identification and estimation of the costs of search. We find that the sequence of points on the...

There is widespread evidence that geographical borders reduce trade. This paper presents a theoretical model capable of providing a succinct comparison of three broad forms of trade barriers involving i) trade costs, ii) localized tastes, and iii) information frictions. Despite being...

In many markets, firms offering low-quality goods are more prominent than firms offering high-quality goods. Then, consumers are perfectly informed about the good of the prominent low-quality firm but incur search costs to bring the high-quality good of a competitor to mind. We analyze under...

Especially in many online markets, consumers can readily observe prices, but may need to further inspect products to assess their suitability. We study the effects of product differentiation and search costs on competition and market outcomes in a tractable model of price-directed consumer...

This paper identifies patterns of cross-sectional and temporal price dispersion-in the Spanish online grocery retail market-and evaluates the extent to which search costs and chain heterogeneity explain such dispersion. We build a data set comprising 836,074 prices for the most popular grocery...

We study how electronic markets that facilitate broader inter-firm transactions affect the vertical scope of emerging IT-enabled extended enterprises. We do so by modeling firms in a three-tier value chain who are each connected to a common electronic market that facilitates direct business...
