The main objective of this article is to present a comparative study of capital assets pricing models (CAPM) with extrapolating capital assets pricing models (X-CAPM) of companies admitted in Tehran Exchange Market which is accomplished for the first time by investigators of this research in Iran. Accordingly, the statistical population under study of this research includes all companies admitt...

The extensive adoption of uniform pricing for branded variants is a puzzling phenomenon considering that firms may improve profitability through price discrimination. In the paper, we incorporate consumers' concerns of price fairness into a model of price competition and show that uniform price for branded variants may emerge in equilibrium. Interestingly, we find that uniform pricing induced b...

When we studied discrete-time models we used martingale pricing to derive the Black-Scholes formula for European options. It was clear, however, that we could also have used a replicating strategy argument to derive the formula. In this part of the course, we will use the replicating strategy argument in continuous time to derive the Black-Scholes partial differential equation. We will use this...

This paper investigates the relationships between firm, industry and market-related variables, strategy, strategy implementation and performance for Philippines exporters. The model follows Cavusgil and Zou (1994) with the addition of strategy implementation as a mediating variable between strategy and performance. We conclude that strategy implementation influences performance, both directly, ...

Previous studies of road congestion pricing problem assume that transportation networks are managed by a central administrative authority with an objective of improving the performance of the whole network. In practice, a transportation network may be comprised of multiple independent local regions with relative independent objectives. In this paper, we investigate the cooperative and competiti...

We introduce a new distributionally robust optimization model to address two-period, multiitem joint pricing and production problem, which can be implemented in data-driven setting using historical demand side information pertinent the prediction of demands. Starting from an additive model, we partitioned-moment-based ambiguity set characterize its residuals, also determines how second-period w...

This paper studies optimal pricing and demand management policies for a firm that faces two streams of order types: one is composed of recurring regular jobs with pre-determined prices (exogenous prices) and the other involves big deals that require pricing proposals (endogenous prices). The probability to secure the big deals diminishes with the quoted price. The authors develop and compare op...

We consider the pricing problem faced by a monopolist who sells a product to a population of consumers over a discrete number of periods. Customers are heterogeneous in both the willingness-to-pay for the product and the arrival time during the selling season. We assume that the seller knows only the support of the customers’ valuations and do not make any other distributional assumptions about...
