In this paper we study how a reduction of consumer switching costs may affect market competition in the wireless telecommunication industry. The reduction of switching costs can be achieved through the implementation of a regulatory policy called Wireless Number Portability (WNP) that allows consumers to retain the same phone numbers when they switch service providers. By r educing consumers' s...

This paper uses a novel empirical setting to explore the association between a firm’s operational risk, managerial monitoring costs, and the level of CEO equity incentives. We investigate a sample of supplier firms that rely on a few large customers for the bulk of their revenues. We predict that supplier firms with higher customer concentration face both higher exogenous idiosyncratic risk and...

Reasons of low effectiveness of radon remedial measures have been studied on several unsuccessfully remediated houses. Based on the thorough analysis, factors responsible for failures are clarified. The possibilities of how to improve the effectiveness of installed measures are also discussed. Experience in this field is documented by several examples of additionally mitigated houses. After app...

This paper presents experimental evidence suggesting that persistant price dispersion that violates the law of one price may be a disequilibrium phenomena. Increasing market concentration increases the pecuniary incentive to give a best response and satisfy the law of one price, that is, a few large rms have a larger pecuniary incentive to solve the allocation coordination problem than many sma...

This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...

This paper examines the long-term behaviour of a discrete-time Footloose Capital model, where capitalists, who are themselves immobile between regions, move their physical capital between regions in response to economic incentives. The spatial location of industry can exhibit cycles of any periodicity or behave chaotically. Long-term behaviour is highly sensitive to transport costs and to the r...

cost of quality analysis is emerged as an effective tool for the industrial managers for pinpointing the deficiencies in the system as well as for identifying the improvement areas by highlighting the cost reduction opportunities. however , this analysis will be fully effective only if it is further extended to identify the cost incurred in ensuring quality in all areas of the supply chain incl...

this paper explores the leverage determinants across firms’ sizesbased on the two main theories behind the capital structure, the trade-offand the pecking order theories. a panel data is sued to find therelationship between capital structure and the variables that proxy forbenefits and costs of debt during 1990 to 2006. our findings show thatboth principles help to explain the capital structure...
