John Christian Langli 


Professor and Head of Department

My research interests are empirical research in accounting, auditing and tax. For the most part, I use Norwegian register data. I have published papers in e.g. The Accounting Review; Accounting, Organization and Society; Accounting and Business Research, The European Accounting Review; Auditing: A Journal of Practice and Theory; Journal of Business, Finance, and Accounting; Management Science, The International Journal of Accounting; Accounting Horizons; Beta; Magma; and Praktisk økonomi og finans.

I am serving as Chairman of the Board of Norsk Regnskapsstiftelse (Norwegian Accounting Standard Setting Board). My current teaching is primarily introductory courses in financial accounting for bachelor students. Previously I’ve teached intermediate and advanced financial accounting, financial statement analyses, valuation, and research methodology. I have supervised more than 70 master theses.

Lærebøker / Textbooks

I have written two textbooks. Fra bilag til bruk. Innføring i finansregnskap og regnskapsanalyse is an introductory textbook. It covers why we have financial statements and how it is regulated, bookkeeping, measurement rules according in the Norwegian Generally Accepted Accounting Principles (which we call God regnskapsskikk (GRS) in Norwegian), and financial statement analyses.  Årsregnskapet is intermediate to advanced. Its has a focus on GRS, but also discusses important differences between GRS and IFRS.
