I model a scenario in which investors do not know the payoff distributions of relatively newer firms and use the payoff distribution of similar well-established firms as starting points. The starting distributions are then adjusted for size, volatility, and other differences. Anchoring bias (Tversky and Kahneman (1974)) implies that such adjustments typically fall short. I show that adjusting c...

We examine the relation between US stock market returns and the US business cycle for the period 1960 2003. We identify two channels in the transmission mechanism. One is through the mean of stock returns via the equity risk premium, and the other is through the volatility of returns. We find that the relation is asymmetric with downturns in the business cycle having a greater negative impact o...

This paper extends the known results on the equivalence between market completeness and the uniqueness of martingale measures for finite asset economies, to the infinite asset case. Our arguments employ results from the theory of linear operators between locally convex topological vector spaces. This theory of linear operators provides an operational approach to the issue of completeness and un...

Using the language of convex analysis we describe key results in several important areas of finance: portfolio theory, financial derivative trading and pricing and consumption based asset pricing theory. We hope to emphasize the importance of convex analysis in financial mathematics and also bring attention to researchers in convex analysis interesting issues in financial applications.

Conditional tests of the International CAPM in previous studies (e.g., Harvey, 1991) help identify predictability but not causality. In this paper, we take an event-study approach to examine if the world market risk premium is particularly higher on prescheduled USmacroeconomic announcement days. Empirically, we apply the Savor andWilson (2014) methodology to daily US stocks as well as foreign ...

In contrast to the existing literature on repeated games that assumes a Þxed discount factor, I study an environment in which it is more realistic to assume a ßuctuating discount factor. In a repeated oligopoly, as the interest rate changes, so too does the degree to which Þrms discount the future. I characterize the optimal tacit collusion equilibrium when the discount factor changes over time...
