Including the entry decision in a Bertrand model with imperfectly informed consumers, we introduce a trade-off at the level of social welfare. On the one hand, market transparency is beneficial when the number of firms is exogenously given. On the other, a higher degree of market transparency...

We analyse optimal environmental policies in a market that is vertically differentiated in terms of the energy efficiency of products. Considering energy taxes, subsidies to firms for investment in more eco-friendly products, and product standards, we are particularly interested in how...

In a variety of purchasing situations, consumers may focus primarily on headline prices, ignoring the full costs associated with acquiring and maintaining a product or service contract. Even when this is the case, it is widely believed that intense competition would adequately protect consumers...

Since the push towards central clearing in derivatives markets after the global financial crisis, an open question has been how the development has affected competition. This paper models imperfect competition between dealers in derivatives markets. Two risk-neutral dealers offer derivatives to...

Compatibility of network products is an important issue in markets for communication technology as well as hard- and software products. Empirical findings suggest that firms competing in these markets typically choose intermediate degrees of product compatibility. We present a strategic...

When experts have superior information on their customers' needs and appropriate treatment/repair/advice is a credence good, there are obvious incentives for opportunistic behavior. What compounds this is that experts regularly make treatment recommendations and price offers only after consumers...

We examine how requiring platforms to give rivals resources, such as data, affects innovation. Using simulations in which an initial firm obtains a head start on rivals and uses that head start to build a valuable resource that subsequently gives it a competitive advantage over rivals when...

We study the impact of platform choice (iOS vs Android) for firms that build apps for smart phones. We merge app data from Sensor Tower® with financial performance data from Crunchbase®. We find that apps that begin on Android have greater average downloads per month. However, apps with the...

Platform interoperability is considered a powerful tool to promote competition in digital markets when network effects are at play. We study the effect of interoperability on competition between two ad-financed platforms, allowing for endogenous multi-homing of consumers. When the platforms are...
