Home Production Market Production and the Changing Allocation of Consumption Expenditures on Service
This article studies the determinants of the quantity of services purchased by consumers in the US over the period 1949–85. Price and income elasticities useful for assessing the likely future demand for services are derived. The theoretical model and empirical estimates differ from traditional approaches by considering, as parameters in the demand function, changes in male and female labour force participation rates and hours worked. One interesting implication of this model is that it permits estimating the shifr of home production of services into market production and therefore an empirical assessment of the degree to which national income growth has been overestimated in the post- war years. 相似文献

It has been assumed that the associative process plays a central and important role in advertising creativity. Yet, although this assumption has long been recognized, we know very little, other than intuitively, about the creative process itself. This paper represents a preliminary inquiry into this gap of advertising theory, formulating an associative model for the individual copywriter's creative process. More specifically, this study examines the relationship of associative ability, attitude, and creative ability, as conceptualized in the presented model. The findings suggest a direct and significant relationship among these three variables. 相似文献

Abstract: We consider the impact of the May 1999 move to screen trading of the LIFFE FTSE 100 index futures contract. This resulted in a narrowing of the effective spread. Spread determinants are broadly similar in the two regimes. The narrowing of the spread appears due to increased competition among traders and a decline in tick-level volatility rather than to the way these or other variables affect the spread. Market depth appears largely unaffected. Under screen trading, realized spreads widen as more limit orders are taken up rather than in relation to order size per se . 相似文献

The authors identify three elements which will influence California's future. First, demographic shifts in the state's population have altered California's ethnic and cultural foundations. Second, the state educational system does not seem prepared to train larger numbers for information work, especially members of its growing ethnic population. Third, almost half the state's workforce is now employed in information-oriented work, whether in the industrial, service, or agricultural sectors. The authors demonstrate that the interaction of these elements has profound implications for California's development. 相似文献

This study examines economic relations between West Germany and the developing countries in the fields of trade, capital flows and migration of labour. Activity in most fields has expanded enormously since the mid-1960s; in addition the traffic has become markedly less one-way. For the purposes of analysis the developing countries are differentiated according to their economic capacity; prospects for co-operation with West Germany appear to differ markedly according to their stage of development. So German development policy, for its part, needs to employ a variety of different strategies. The more highly developed the partner country, the more the field can be left to private initiative, supported by a liberal foreign trade regime. 相似文献
