Abstract We provide a theoretical model of privacy in which data collection requires consumers' consent and consumers are fully aware of the consequences of such consent. Nonetheless, excessive collection of personal information arises in the monopoly market equilibrium which results in excessive loss of privacy compared to the social optimum. The main mechanism for this result is information externalities and users' coordination failure in which some users' decision to share their personal info...

Using detailed trip-level taxi and for-hire-vehicle data and new incident-level complaints data, we study how the entry of Uber and Lyft has affected the quality of taxi services in New York City. In a panel setting with 263 NYC taxi-zones over the time period from 2014 to 2017, we find that increased competition measured by the number of daily Uber/Lyft trips in a given taxi-zone has led to more complaints regarding a variety of service quality dimensions such as unsafe driving, rude behavior a...
While belief disagreement models have played an important role in explaining bubbles, over-trading, and speculation, measuring social welfare in those models has been a challenge. This is because the social planner may not know the objective probabilities or whose subjective beliefs to elect under belief disagreements. We propose a novel welfare criterion that endogenously determines sensible welfare weights based on competitive equilibrium allocation as a benchmark. Applying it to several model...

The Internet and mobile revolutions gave birth to many information-based platforms that have low entry costs with highly imitable business models. Exploiting granular deal-level data, we empirically study the U.S. daily deals promotion market, characterized by frequent multihoming of consumers and merchants leading to intense competition in over 150 regional markets between two major platforms, Groupon and LivingSocial. Consistent with the competitive pressure due to prevalent multihoming on the...

In 2012 Pennsylvania amended its Oil and Gas Act to tighten regulations on development of shale gas resources. Three key pecuniary provisions were annual well fees, increased bonding requirements, and higher penalty limits for violations. We analyze the effects of these mandates on well operator behavior using data on well operations and inspections over the period 2000–2013. After deriving theoretical predictions, we empirically examine each provision’s effect on firm behavior in two aspects: (...

AbstractScholars and practitioners debate whether to expand the scope of the right to be forgotten—the right to have certain links removed from search results—to encompass global search results. The debate centers on the assumption that the expansion will increase the incidence of link removal, which reinforces privacy while hampering free speech. We develop a game-theoretic model to show that the expansion of the right to be forgotten can reduce the incidence of link removal. We also show that ...

In this article we study second-degree price discrimination by a two-sided monopoly platform. We find novel distortions that arise due to the two-sidedness of the market. They make the standard result "no distortion at top and downward distortion at bottom" not holding. They generate a new type of non-responsiveness, different from the one found by Guesnerie and Laffont (1984). We also show that the platform may mitigate or remove non-responsiveness at one side by properly designing price discri...

It is found that the three most frequently employed sources are customers and suppliers, internet, and specialized publications for both SMEs and large firms. And it is reported that there is a positive relationship between firm size and the frequency of assessing certain information sources such as sector legislation, annual reports, and external consulting. Large companies often rely on specialized information sources such as external consulting. This study shows some possible solutions to inf...
