Supply Function Equilibria in Networks with Transport Constraints Pär Holmberg and Andrew Philpott

Transport constraints limit competition and arbitrageurs.possibilities of exploiting price differences between commodities in neighbouring markets. We analyze a transport-constrained network with local demand shocks, where spatially distributed oligopoly producers compete with supply functions, as in wholesale electricity markets. Uniqueness and existence results are proven, and we are able to explicitly solve for symmetric supply-function equilibria in some special cases.

Sick of Inequality?

An Introduction to the Relationship between Inequality and Health

Sick of Inequality.jpg

In this book Andreas Bergh, Therese Nilsson, IFN and Lund University, and Daniel Waldenström, IFN and Paris School of Economics, France, review the latest research on the relationship between inequality and health. What does inequality mean for our health? Does increasing income inequality affect outcomes such as obesity, life expectancy and subjective well-being?


Seminars organized by IFN


To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
