Per Krusell is Professor of Economics at the Institute of International Economics at Stockholm University. His research is in the broad field of macroeconomics.

In recent years, Per Krusell has been running a major research project in the climate field. The idea is to build models that link advanced climate research with modern macroeconomic analysis. In a long-term initiative, an interdisciplinary network of economists and natural scientists has been built up at Stockholm University.

- Our aim is to understand the problems posed by climate change and how it affects countries' economies in different ways. Today, there is a lot of interest in these issues and we have contributed to basic research in this area. Among other things, we have developed a formula for how carbon dioxide should be taxed.

Studies of inequalities

Another strand of Per Krusell's research is the study of factors behind inequalities between households in terms of income and wealth. Understanding inequalities is important, among other things, to know what effect economic instruments can have.

One of the latest projects in this area concerns the financial behavior of the wealthiest. How do they make decisions about capital accumulation and savings?

- "The very richest are an extremely small group, but they own the companies and decide how investments are made in Sweden. Understanding how they reason and what drives them is important for the whole of society," says Per Krusell.

He is delighted to have been awarded the Söderberg Research Professorship.

- It is an award that is rare to receive and it feels like a recognition of the research I have conducted historically. It will also mean a lot for the funding of my work in the future. 

Per Krusell was awarded the Söderberg Prize in Economics in 2007. He is a member of the Kungl. Vetenskapsakademien since 2003 and is a member of the Committee for the Prize in Economic Sciences in Memory of Alfred Nobel. From 2004 to 2009 he was Professor of Economics at Princeton University. Prior to that, he held positions at the University of Rochester, the University of Pennsylvania and Northwestern University. Since 2014 he has also been Centennial Professor at the London School of Economics and Political Science.
