This paper studies regulatory policy interventions aimed at protecting sticky consumers who are exposed to exploitation. We model heterogeneous consumer switching costs alongside asymmetric market shares. This setting encompasses many markets in which established firms are challenged by new...

This paper studies regulatory policy interventions aimed at protecting vulnerable consumers who are disengaged and thus exposed to exploitation. We model heterogeneous consumer switching costs alongside asymmetric market shares. This setting encompasses many markets in which established rms are...

We consider a dynamic oligopoly on the beer market and study the differential effects of switching costs on product prices, market shares, and profits. Our demand estimation results show large differences in brand loyalty, and switching costs across customer income segments and beer brands. Our...

The Economist puts it best: “The details around network neutrality, the principle that internet-service providers (ISPs) must treat all sorts of web traffic equally, can be mind-numbingly abstruse. But they fuel passion, nonetheless.” A primer already exists in Greenstein, Peitz and Valletti...

In this paper, we use a unique database on switching between mobile handsets in a sample of about 5,000 subscribers using tariffs without commitment from a single mobile operator on monthly basis between March 2012 and December 2014. We estimate discrete choice model in which we account for...

In this paper, we use a unique dataset on switching between mobile handsets in a sample of about 8,623 subscribers using tariffs without handset subsidies from a single mobile operator on a monthly basis between July 2011 and December 2014. We estimate a discrete choice model in which we account...

In this article I analyze the effects of a recent reform intended to decrease switching costs in the cellular industry. The reform, implemented in Chile in 2012, allowed cell phone users to switch operators without any contract restriction while keeping their wireless number. Its aim was the...

This paper models competition between two firms, which provide broadband Internet access in regional markets with different population densities. The firms, an incumbent and an entrant, differ in two ways. First, consumers bear costs when switching to the entrant. Second, the entrant faces a...

This paper estimates demand for quadruple play mobile tariffs using a database of subscribers to a single mobile operator from a single town in a European country which has full coverage with both ADSL and FTTH broadband technologies. Based on the demand estimation we find that consumer...

We develop a consumer level demand model of telecommunications and broadcasting services considering an exhaustive set of alternatives available to consumers including bundled services. We then estimate switching costs associated with bundling. Previous studies consider restricted choice sets...
