Abstract

Mandatory network unbundling is one of the most important topics in regulatory economics today. The concept has crucial importance in the deregulation of many previously regulated industries including electricity, telecommunications, gas and railroads. Upon initial examination, determining the correct input prices would seem important for sending the correct price signals to the entrants for their efficient make-or-buy decisions. However, Sappington uses a standard Hotelling location model to show that input prices are irrelevant for an entrant’s make or buy decision. In this study, it is shown that this result is closely related to the degree of product differentiation when firms are engaged in price competition. Specifically, it is shown that input prices are irrelevant when firms produce homogeneous products, but are relevant for make-or-buy decisions when the entrant and incumbent produce differentiated products. These results suggest that, in general, it is important for regulators to set correct prices in order to not distort the entrants’ efficient make-or-buy decisions.

Abstract

The current study takes a contingency theory approach to the relationship between market leadership and a variety of marketing strategy concepts making up a firm’s strategic profile, including a firm’s Miles and Snow strategy type, market growth, service growth, service focus, market coverage, the Porter strategy group, and market orientation.  The results of the study support this approach, showing that at least six of the seven strategic contingency combinations exhibit a significant relationship to market share.  Utilizing a sample drawn from the financial services industry, it is found that firms possessing a recommended “fit”, as when market leader firms exhibit a more aggressive marketing strategy profile, tend to have higher levels of market share.  The results of the study also reveal that a firm’s market share performance is related to the total number of strategic “fits” between the firm’s market leadership position and the various components of the firm’s strategic profile.

The increasing human needs recently and the dependence of the most of these needs on the energy make this sector more and more significant everyday. Should it known that how the other sectors are depended on the sub-sectors of the energy, it would be so easy to produce policy. Input-output analysis as a unit of economic activity researches the sectors and especially the exchanges of intermediate input between the sectors. So input-output analysis is a major instrument in terms of enabling to research the production and usage of the outputs of the productive sectors in economic scale, in sectoral level and quantatively. In the analysis made by using the input-output tables of Turkey Statistics Office for 2002 it was observed that energy sector has been a key sector recently. Also the relation of energy sector with the others was searched and the most input-output marketing sector of the energy sector was analyzed.

In this study, whether the number of ships departing and arriving in Turkish ports has effect on industrial production index and total trade (the sum of import and export) was investigated by regression analysis between 2004-2010 years. According to the results obtained, the increase of the number of ship transportation in Turkey creates a positive and statistically significant effect on industrial production index and total trade.

Technology Acceptance Model (TAM) is a model by Davis (1989) which was developed after improving his ideas previously-used in his doctoral dissertation that states the acceptance of the new technology of end-users can be formed by the aid of (1) Perceived usefulness and (2) Perceived ease of use. Technology Acceptance Model guided the ideas which defending that success of the information systems – technologically – can be achieved not only by technical and administrative features of the users but also by their personal characteristics, expectations and perceptions; user’s perception on various issues can affect this success as well.

This study examines the user factor in order to determine the success of Enterprise Resource Planning (ERP) systems, within the framework of TAM. 236 firms which use ERP softwares participated in the survey study. Results prove that perceived ease of use and perceived usefulness have a positive and statistically significant effect on ERP implementation success as well as on perceived organizational performance. These results reveal that all hypotheses have been supported and the study is coherent the findings of similar studies within the literature.
