Applied econometrics, non-parametric econometrics, production analysis, and consumption analysis.
Among the questions that Per Hjertstrand tries to answer with his research:
- Is it possible to test whether firms maximize profits and minimize costs? If so, how are these hypotheses tested?
- If it can be tested, does data show that firms efficiently maximize profits and minimize costs?
- How to test if individuals/households maximize utility when consuming goods and services?
- Does data show that individuals/households efficiently maximize utility?
- What kind of information and how much information about the preferences of individuals, households and firms can be found in consumption and production data?
Why Entrepreneurs Choose Risky R&D Projects ‒ But Still Not Risky Enough
Erika Färnstrand Damsgaard, Per Hjertstrand, Pehr-Johan Norbäck, Lars Persson and Helder Vasconcelos
Per Hjertstrand's research interest is mainly econometrics, with focus on production and consumer analyses. At present, he is working on a project aiming at developing statistical procedures for testing if fundamental productions and consumer models can explain observed data.
