Network Competition with Income Effects Thomas Tangerås


I generalize the workhorse model of network competition to include income effects in demand. Empirical work has shown income effects to be positive and statistically significant. Income effects deliver theoretical results consistent with regulatory concern about excessive termination rates: Unregulated network operators competing in non-discriminatory retail contracts negotiate termination rates above cost for any positive income effect. This also holds when operators discriminate between on-net and off-net calls if networks are differentiated. Operators profit from increasing termination rates above cost under second-degree price discrimination if a sufficient share of consumers prefer on-net/off-net contracts and their subscription demand is relatively inelastic.

Pages-from-2019-Calmfors-Gassen---Integrating-Immigrants-into-the-Nordic-Labour-Markets.gif

Denmark, Finland, Norway and Sweden face similar problems of integrating large groups of immigrants, especially low-educated ones from outside the EU, into their labour markets. In this volume, edited by Lars Calmfors, IFN, and Nora Sánchez Gassen in cooperation with researchers from across the Nordic Region analyse how labour market integration of immigrants can be promoted.
