Several national cases are analysed: Britain, as the Workshop of the World; France, Germany, Switzerland and the US, as core economies; and Italy and Spain as countries on the European periphery. The main question that we address is why some cotton industries vertically integrated their production and commercialisation processes, but others did not. We present a model that combines industrial district size and product differentiation to explain why vertical integration was present in most cases and why there was vertical specialisation in Lancashire and Lowell. <br> Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2072/4994 title: Induced aggregation operators in decision making with the Dempster-Shafer belief structure authors: Merigó Lindahl, José M.; Casanovas i Ramón, Montserrat <br>abstract: We study the induced aggregation operators. The analysis begins with a revision of some basic concepts such as the induced ordered weighted averaging (IOWA) operator and the induced ordered weighted geometric (IOWG) operator. We then analyze the problem of decision making with Dempster-Shafer theory of evidence. We suggest the use of induced aggregation operators in decision making with Dempster-Shafer theory. We focus on the aggregation step and examine some of its main properties, including the distinction between descending and ascending orders and different families of induced operators. Finally, we present an illustrative example in which the results obtained using different types of aggregation operators can be seen. <br> Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2072/4980 title: Technological Change and Immigration authors: Dilmé, Francesc <br>abstract: We develop a simple model where two technologies are available to produce the same good, and we study under what conditions both will be used. We use the model to analyze the consequences of the simultaneous use of two different technologies for the economic variables and economic growth. Finally, we explore how migrations of factors affect the technological change and the performance of the economy. <br> Sun, 29 Oct 2006 22:58:59 GMT http://hdl.handle.net/2072/4977 title: Cost stickiness revisited: Empirical aplication for farms authors: Argilés Bosch, Josep M.; Garcia Blandón, Josep <br>abstract: This article reviews previous research regarding cost stickiness and performs an empirical analysis applied to a sample of farms. It recognizes that modelization of cost stickiness is a particular case of representation of cost variations as a function of output variations. It also discusses methodological issues and analyses cost stickiness for all registered farm costs and opportunity costs of family work. Costs exhibit a considerable level of rigidity. Even for variable costs, a decrease in activity involves a lower decrease in costs than the amounts involved when activity increases. While registered indirect costs slightly decrease when activity decreases, opportunity costs always increase. The study provides empirical evidence that cost stickiness is significantly reduced with better management decision practices. <br> Sun, 29 Oct 2006 22:58:59 GMT
