Dr. Croitoru joined McGill's Faculty of Management in the Fall of 2000, where he teaches Financial Economics at the doctoral level and Investments and Portfolio Management at the undergraduate level.
Dr. Croitoru's research has been concerned primarily with the equilibrium pricing of financial assets in the presence of imperfections (such as taxation, transaction costs for the international shipment of goods, or portfolio constraints such as restrictions on short sales). In his doctoral dissertation, he has examined how apparent inconsistencies in asset prices can arise within the framework of a rational equilibrium model. A useful economic role for the type of arbitrage activity that exploits these pricing discrepancies (and is often blamed for increasing market volatility) was demonstrated. Another chapter incorporated complex features of the tax system into the analysis of individual investment decisions and equilibrium security prices.
Dr. Croitoru's other research interests include international finance, the role of incomplete information and heterogeneous beliefs, and strategic behavior in financial markets. He has presented his research at the American Finance Association and the Western Finance Association meetings, as well as other conferences and universities in Europe and North America.
Dr. Croitoru's research has been published in the Journal of Financial Economics, the Journal of Mathematical Economics and the Review of Financial Studies.
