In an arbitrage-free economy with non-zero bid-ask spreads, the presence of payoffs, whose price is lower than the price of another payoff where the former dominates the latter, can not be discarded in general. However, their presence is a true market anomaly when the former price corresponds to...

This paper discusses the PCS Catastrophe Insurance Option Contracts, providing empirical support on the level of correspondence between real quotes and standard financial theory. The highest possible precision is incorporated since the real quotes are perfectly synchronized and the bid-ask...

Several authors have introduced different ways to measure integration between financial markets. Most of them are derived from the basic assumptions about asset prices, like the Law of One Price or the absence of arbitrage opportunities. Two perfectly integrated markets must give identical...

Bernardo and Ledoit (2000) develop a very appealing framework to compute pricing bounds based on what they call gain-loss ratio. Their method has many advantages and very interesting properties and so far one important drawback: The complexity of the numerical computation of the pricing bounds....

To analyze the economic significance of pricing errors of stock index options, a system of linear inequalities is developed which completely characterizes all risk arbitrage opportunities which arise if a well-behaved pricing kernel does not exist. The Stochastic Arbitrage system can account for...

In an arbitrage-free economy with non-zero bid-ask spreads the existence of payoffs whose price is lower than the price of a dominated payoff cannot be discarded in general. However, when the former price corresponds to trivial portfolios which involve buying or selling one unit of the basis...

In this paper it is shown how the set of all portfolios which are second-order stochastic dominance efficient can be characterized by using a series of mixed-integer linear constrains. Our derivation employs a combination of the first-order conditions of the utility maximization problem together...

We present a generalization of Cochrane and Saá-Requejo's good-deal bounds which allows to include in a flexible way the implications of a given stochastic discount factor model. Furthermore, a useful application to stochastic volatility models of option pricing is provided where closed-form...

The expansion of videoconference lectures has raised concerns about the potential harm they could represent for the attention and engagement of college students. By observing the behavior of a large population of participants in an identical flipped course before and after March 2020, levels of...
