This article explores the effects of political structure on rulers' monopolistic gains and investment decisions in the context of the medieval milling industry in northern France, 1150–1250. Using Salop's spatial model, this article aims to show that political fragmentation increased investment in watermill construction because it reduced the capacity of rulers to limit competition from neighbouring mills. The calculations demonstrate that competition significantly reduced rulers' income from watermills and that the construction of more than 50 per cent of these mills cannot be economically ‘justified’ unless rulers' profit maximization over joint production is considered, and revenues from additional labour allocated to wheat production is included. 相似文献

The environmental impact of laundering is dependent on the laundry methods used by households. This study investigates the relation between laundry methods (frequency, load size and wash temperature) and the composition of wash loads. Three definitions for the composition of wash loads are used: the respondent's classification and two objective definitions. These are constructed in two different ways from three specific characteristics of the textiles: colour, textile fibre and the type of article. The data are from a survey with a 2-week diary about laundry practices of 1026 Dutch households in 1990. The results show that all three definitions of the composition of wash loads can explain one factor of the laundry method, wash temperature; frequency and load size, however, are not influenced by the composition of the wash load. 相似文献

Summary Tax effects on labour market and allocation are analysed with a sectoral model which is based on the microeconomic theory of the behaviour of economic agents. The model contains a highly disaggregated household sector, an enterprise sector, equilibrium unemployment on the labour market and a detailed modelling of institutional aspects of the tax and social security system. The model is calibrated for 1985. Simulation results show that temporary increases of world trade and higher value-added tax rates do not affect the equilibrium unemployment rate in the long run. A higher replacement rate of unemployment benefits increases unemployment and a tax reform containing lower marginal and average tax rates reduces unemployment.The authors thank F.J.H. Don, C.J.J.

Samples of brown 50% polyester/50% cotton momie cloth with a fluorocarbon finish were commercially laundered using a carbonate-built detergent in soft (0 ppm) water. The appearance of the laundered samples was assessed by subjective pilling ratings and instrumental colour determinations; the performance properties examined were tear and tensile strength, abrasion resistance and ability to release oil. The results showed that pilling was at its maximum after 20 launderings. The depth of colour decreased with increased number of cycles and, in most cases, was not accompanied by change of hue Tear and tensile strength were not affected by the laundering process. The fluorocarbon finish on the unlaundered control increased the weight loss due to Accelerator abrasion, thus that due to repeated launderings was significantly less. The finish protected the fibres from flex abrasion, increasing the number of cycles required to rupture the fabric and only the sample laundered 60 times had significantly greater resistance. The ability to release oil decreased with increased number of launderings. Oil remaining in the fabric was located in the interstices between yarns. 相似文献
