Determinants of Financial vs. Non Financial Stock Returns: Evidence from Istanbul Stock Exchange

We estimate a four-factor model for a sample of financial and nonfinancial firms traded on the Istanbul Stock Exchange (ISE). The factors relate to market return, interest, inflation and exchange rates. By investigating the effects of these factors simultaneously for different exchange rate regimes, we show that market return, interest, inflation, and exchange rates play a separate role in financial and nonfinancial firms´ stock returns. We also show that all factors are priced during the period of free float. These results are important for determining financial institutions' cost of capital and for identifying the risks that should be hedged

Proper and Standard Risk Aversion in Two-Moment Decision Models

This paper shows that such compatibility does hold for the concept of standard risk aversion but not for the concepts of proper risk aversion and proper prudence.
