In this paper, we use pattern clustering and multivariate analysis of variance methods to analyze the daily load patterns in Ontario, Canada, in order to determine the impact of the time of use (TOU) rate implementation. Our findings show that in the first year after the implementation, there...

In a market with transaction costs, generally, there is no nontrivial portfolio that dominates a contingent claim. Therefore, in such a market, preferences have to be introduced in order to evaluate the prices of options. The main goal of this article is to quantify this dependence on...

We prove limit theorems for the super-replication cost of European options in a Binomial model with friction. The examples covered are markets with proportional transaction costs and the illiquid markets. The dual representation for the super-replication cost in these models are obtained and...

We introduce a notion of volatility uncertainty in discrete time and define the corresponding analogue of Peng’s G-expectation. In the continuous-time limit, the resulting sublinear expectation converges weakly to the G-expectation. This can be seen as a Donsker-type result for the G-Brownian...

In the list of possible scapegoats for the recent financial crises, mathematics, in particular mathematical finance has been ranked, without a doubt, as the first among many and quants, as mathematicians are known in the industry, have been blamed for developing and using esoteric models which...

Surveys have shown that, in general, developing countries tend to regulate the set-up processes for firms more intensively than developed countries. In particular, while many developing countries tend to integrate licensing requirements in the set-up process ('set-up licensing'), the more...
