Pricing ladders are widely used in the airline industry to define the discrete set of prices that can be charged for seats on a flight. We consider the factors that affect the setting of these ladders for oneway economy tickets. The minimum and maximum fares are assumed to be fixed and we focus on maximising the revenue generated on a flight by changing the spacing of the intermediate fares. Th...

The predominant explanation for arbitrage crashes is a lack of investor capital to exploit mispricing. This paper shows that slow moving capital is only partially responsible for the 2005 and 2008 arbitrage crashes in the convertible bond market. Even when convertible bonds where underpriced, investors were still buying strictly dominated straight bonds from the same issuers. This finding sugge...

This paper seeks to detect hot and cold IPO cycles in the Tunisian share market using a Markov regime switching model. Using a set of IPO activity measures (number of IPOs, level of underpricing, market conditions and duration), we establish a model which estimates these activity measures in hot and cold periods respectively. We depict the turning points from 1998 to 2012 for each activity meas...

In modified Libor masek method mainly in preprocessing phase in segmentation we are using Nelder-Mead search method also called as simplex method for calculation of center coordinates, radius and threshold...

Effective business development strategies often begin with market segmentation, which involves the grouping of customers and non-customers with similar characteristics. Segmentation is useful to the extent that customers within a segment have similar purchasing behavior and/or profitability that differs from customers in other segments. Many companies segment their markets and customers using a...

This paper provides an innovative segmentation approach stemming from the combination of cluster analyses and fuzzy learning techniques. Our research provides a real case solution in the Spanish energy market to respond to the increasing number of requests from industry managers to be able to interpret ambiguous market information as realistically as possible. The learning stage is based on the...

The simultaneous treatment of two interrelated and well-known tasks from strategic marketing planning, namely the determination of competitive market structure (CMS) and market segmentation, is addressed via application of the ”Self-Organizing (Feature) Map” (SOM) methodology, as originally proposed by Kohonen (1982). In the present paper, some major aspects of the methodological basis of the S...

This paper models interaction between groups of agents by means of a graph where each node represents a group of agents and an arc represents bilateral interaction. It departs from the standard Katz-Shapiro framework by assuming that network benefits are restricted only amongst groups of linked agents. It shows that even if rival firms engage in Bertrand competition, this form of network extern...

One of the major industries to meet the expansion goals in human, social, and economic aspects is herbal medicine. Marketing department, producers, and entrepreneurs play an important role in applying potentials in this industry, but, as herbal medicine scholars argue, herbal medicine market share in Iran is less than 4 percent.
