We propose a novel portfolio selection approach that manages to ease some of the problems that characterise standard expected utility maximisation. The optimal portfolio is no longer defined as the extremum of a suitably chosen utility function: the latter, instead, is reinterpreted as the...

This paper investigates the testable restrictions on the time-series behavior of equity premia implied by a representative agent model whose state- and time-non separable preferences are subject to taste shocks. The model nests state- and time-separable preferences with and without taste shocks...

We propose a Bayesian methodology that enables banks to improve their credit scoring models by imposing prior information. As prior information, we use coefficients from credit scoring models estimated on other data sets. Through simulations, we explore the default prediction power of three...

The purpose of this paper is to investigate the validity of some behavioral conjectures as alternative explanations of bank risk-taking behavior. We especially focus on the different valuation of gains and losses relative to a reference point, and the changing attitude toward risk conditional on...

This paper investigates the joint hypothesis of market efficiency and unbiasedness of futures prices for the copper futures contract traded on the London Metal Exchange. This contract is of particular importance given the usage and properties of the underlying commodity and its highest share of...

This paper introduces a new method for evaluating a trading system based on its past performance. The method is a hypothesis test that asks whether the system is making random trades. The test controls for price behavior during the test period and the trade characteristics of the system being...

This paper seeks whether the intraday patterns observed in most stock markets hold for an individual stock from the Istanbul Stock Exchange where the trading ceases for two hours during lunchtime. It investigates the most treated topics in market finance like liquidity, returns and volatility...

Using one of the key property of copulas that they remain invariant under an arbitrary monotonous change of variable, we investigate the null hypothesis that the dependence between financial assets can be modeled by the Gaussian copula. We find that most pairs of currencies and pairs of major...

Several studies have recommended reliance on subordinated debt as a tool for monitoring banks by investors and for enhancing depositors’ protection. However, subordinated debenture increases the level of leverage and thus the probability of costly failure. We propose a novel financial...

We test whether liquidity is priced in the euro-denominated corporate bond market. We use the Arbitrage Pricing Theory to control for other sources of risk. Yields are used to measure the bonds' expected returns and liquidity is approximated by four indirect measures: issued amount, age, number...
