In this thesis, the relationship between some aspects of industrial market structure and industry price-cost margins or profit-revenue ratios is investigated. This done mainly by building mathematical models based upon tenet profit maximisation. Empirical tests hypotheses developed are carried out using regression analysis on recent UK data. After an introductory chapter, arguments successively taking structural features into account. Thus initially, problems involved in relating...

This paper considers the importance of countervailing power, manifested as effects increased retail concentration on consumer prices and welfare within a market setting where imperfectly competitive retailers negotiate intermediate with monopoly supplier. Only when retailer services are regarded very close substitutes do final fall following reduction in number retailers. Even these circumstances, social benefits power may not be realised supplier seek to protect its profits by using refusal...

INDUSTRIAL economists have been studying the relationship between profitability and concentration using cross-industry samples for many years now. However, as sometimes happens, once it appeared that some consensus had achieved: With few exceptions, market industry are positively correlated (Peltzman, [I977, p. 229]), people began to question interpretation of those results. In particular, Demsetz (e.g. [I973], [I974]) others suggested that, rather than concentration/ power leading higher...

Across the European Union, concentration in food retailing at national level has been increasing for some time, but increasingly multinational retailers have extending their international reach. In process, aggregate risen sharply over last few years. addition, presence of buyer groups, representing different retail interests, adds to characterisation procurement markets as highly concentrated. Also level, cross‐border alliances amongst large emerged. We consider implications these features...

Significance Sensory inputs are known to control aging. The underlying circuitry through which these cues integrated into regulatory physiological outputs, however, remains largely unknown. Here, we use the taste sensory system of fruit fly Drosophila melanogaster detail one such circuit. Specifically, find that water-sensing signals alter nutrient homeostasis and regulate a glucagon-like signaling pathway govern production internal water production. This metabolic alteration likely serves...
