This paper studies a dynamic two-sided market in which consumers face switching costs between competing products. I first show that, in a symmetric equilibrium, switching costs lower the first-period price if network externalities are strong. By contrast, switching costs soften price competition in...

This paper considers firms' incentives to invest in local and exible resources when demand is uncertain and correlated. Before demand is realized, two firms decide to invest in their local capacity. Provider(s) of exible resource observe these decisions and invest in their capacity. After demand is...

This paper develops a theory of sequential investments in cybersecurity in which the software vendor can invest ex ante and ex post. The regulator can use safety standards and liability rules as means of increasing security. A standard is a minimum level of safety, and a liability rule states the...

The New Empirical Industrial Organization (NEIO) literature allows to analyze competition, market power and welfare implications of public policies. This literature is based on the estimation of consumer substitution patterns, that is on the estimation of demand models. Standard discrete choice...

We study how net neutrality regulations affect a high-bandwidth content provider (CP)'s investment incentives to enhance its quality of services (QoS) in content delivery to end users. We find that the effects crucially depend on whether the CP's entry decision is constrained by the Internet...

We introduce a proximal alternating linearized minimization (PALM) algorithm for solving a broad class of nonconvex and nonsmooth minimization problems. Building on the powerful Kurdyka–Łojasiewicz property, we derive a self-contained convergence analysis framework and establish that each bounded...
