We address the issue of hedging in in nite horizon markets under cone constraints on the number of shares of assets. We show that the minimum cost of hedging a liability stream is equal to its largest present value with respect to admissible stochastic discount factors, thus can be determined without nding an optimal hedging strategy. We develop an algorithm by which an optimal portfolio in one...

The Euler (or gradient) allocation technique defines a financial institution’s marginal cost of a risk exposure via calculation of the gradient of a risk measure evaluated at the institution’s current portfolio position. The technique, however, relies on an arbitrary selection of a risk measure. We reverse the sequence of this approach by calculating the marginal costs of risk exposures for a p...

The magnitude and frequency of recent financial crises underscore the importance of understanding financial instability for the purpose of crisis prevention and crisis management. This paper brings together and adds structure to the theoretical literature on financial instability and the implications they carry for policy-makers. In addition to clarifying the theoretical underpinnings for study...

I present evidence of inefficient information processing in equity markets by documenting that negative information withheld by securities analysts is incorporated in stock prices with a significant delay. I estimate the extent of the withheld negative information based on the proportion of analysts who stop revising their annual earnings forecasts. This measure predicts negative earnings surpr...

I test theories of the recent financial crisis by studying how banks’ pre-crisis investments connect to their CEOs’ beliefs. Using different proxies for beliefs, I find banks with larger housing investments and worse crisis performance had CEOs who were more optimistic ex ante. Banks with the most optimistic CEOs experienced 20 percentage points higher real estate loan growth, and 15 percentage...

This paper provides a new hedge fund replication method, which extends Kat and Palaro (2005) and Papageorgiou, Remillard and Hocquard (2008) to multiple trading assets with both long and short positions. The method generates a target payoff distribution by the cheapest dynamic portfolio. It is regarded as an extension of Dybvig (1988) to continuous-time framework and dynamic portfolio optimizat...

This research aims to analyze and to compare the ability of different mathematical models, such as artificial neural networks (ANN) and ARCH and GARCH models, to forecast the daily exchange rates Euro/U.S. dollar (USD), identifying which, among all the models applied, produces more accurate forecasts. By empirically comparing the different mathematical models developed in this research, the tra...

Credit card default losses increased dramatically in the 80s and 90s, from 3% to over 5% of outstanding debt. We explore whether technological progress in debt collection is behind this change by developing a new theory featuring costly state verification with signals. We motivate our approach by the predominance of informal bankruptcy in the credit card market, which necessitates the costly in...
