Mattias research relates to capital markets. In recent years, he has conducted accounting-based tests of market efficiency (e.g. Hamberg and Novak, 2010), studies of accounting information relevance for shareholders (e.g. Beisland & Hamberg, 2013), and studies of how firm’s respond to new accounting standards (Hamberg, Paananen & Novak, 2012). Mattias also work with research in corporate finance. He has conducted studies on international corporate acquisitions (Hamberg, Overland & Lantz, 2013), issues of new equity (Hamberg & Jeppson, 2011) and initial public offerings (Hamberg, 2004). Recently, Mattias has paid a particular interest to the association between financial reporting and corporate goverance. This includes, for example, the role that audit committees play in the monitoring of management (Hamberg, Charri & Johanson, 2013), the IFRS adoption's effects on foreign investments (Hamberg, Mavruk & Sjogren, 2013), and the extent to which founders create shareholder value (Hamberg, Fagerland & Nielsen, 2013; Frank & Hamberg, 2015; 2016). Essentially all of his research is empirical, quantitative and based on Swedish data.
Mattias contributes to the international research community in several ways. For example, he is a regular referee for international journals such as the European Accounting Review, the Journal of International Business Studies, the International Business Review and Managerial Finance. His research has been presented at more than thirty international conferences. Furthermore, Mattias has acted as opponent of a doctoral thesis (Copenhagen Business School) and he holds a permanent position at the Norwegian School of Economics in Bergen (Norway) where he regularly teaches company valuation, research methodology and a doctoral course in empirical financial accounting.
Mattias has taught and administered university courses at the bachelor, master, executive MBA and doctoral levels. Although he is most comfortable teaching financial statement analysis and valuation, his teaching covers most topics in financial accounting and corporate finance, including financial reporting, company valuation, risk management, corporate governance and international financial management. Over the years, he has been particularly interested in empirical research designs within the area of capital market based accounting research. For this reason, he has taught an advanced Master level course at the Norwegian School of Economics (2002-2013).Over the years, Mattias has supervised more than one hundred bachelor and master theses. He has supervised several doctoral students who completed their degrees.
