Since the second half of the past century, increasingly flexible organizational forms have been appearing among firms. However, while hierarchies are easily described, too few mathematical tools are available for flexible organizations. In this article, two measures are proposed in order to assess the state and trend of flexible organizations. The first of these measures is based on information waste, which occurs whenever information is classified into categories. The second measure is based on duplication of operations. The underlying idea is that firms have an endogenous drive towards organizational configurations where waste of information and duplication of operations are minimized. However, environmental uncertainty may require some flexibility, which is ensured by cognitive processes that discard some information as well as by parallel undertaking of similar actions. 相似文献

We estimate the household’s marginal willingness to pay for housing attributes in the rent-controlled sector, so where rents are not freely market determined. The application of hedonic price approaches to obtain estimates of the household’s value of housing characteristics is then invalid. We apply an alternative estimation approach based on residential mobility. In our application, we focus on the households’ willingness to pay for number of rooms as well as the willingness to pay to avoid a long commuting distance. Our estimates appear plausible. For example, for households in the rent-controlled sector are willing to pay about 7% of their household income for an additional room. The implied marginal costs of commuting are about €0.17–€0.23 per (one-way) kilometre. 相似文献

Evidence Theory is a branch of the mathematics of uncertain reasoning that entails profound epistemological differences with respect to Probability Theory. In fact, its paradigmatic situation is the judge who must evaluate testimonies, rather than the gambler who must evaluates odds. Unlike a gambler, who faces a definite set of possibilities, a judge maybe forced to change her evaluation because of novel possibilities suggested by unexpected testimonies. In this sense, Evidence Theory provides a formalization of some among Shackles intuitions. While the details of the connections between Shackle's theory and Evidence Theory have been explored elsewhere, this article is devoted to a detailed explanation of the working of Evidence Theory. An example is discussed in detail and several domains of application are briefly sketched. 相似文献

An empirical analysis is presented of union growth in The Netherlands over the past decades. The analysis shows that the effect of changes in the industrial structure is very small. It appears that union growth is influenced by wage growth and by unemployment. If real wages increase more than labour productivity or if unemployment declines union membership increases. 相似文献

In the Generalized Bin Packing Problem (GBPP), given two sets of compulsory and non-compulsory items characterized by volume and profit and a set of bins with given volume and cost, we want to select the subset of profitable non-compulsory items to be loaded together with the compulsory ones into the appropriate bins in order to minimize the total net cost. Lower and upper bounds to the GBPP are given. The results of extensive computational experiments show that the proposed procedures are efficient and the bounds are tight. 相似文献

Consumers prefer bonus packs, as opposed to price discounts, for healthy foods, but they want a price discount rather than a bonus pack for indulgent foods (Mishra & Mishra, 2011). This study conceptually replicates and extends this finding to show that consumers are more responsive to changes in price than to changes in package size for indulgent food options, whereas they are more responsive to changes in package size than to changes in price for healthy food options. 相似文献

We examine the welfare effects of partisanship in a model of checks and balances. An executive makes a policy proposal and an overseer then decides whether or not to veto the executive's proposal. Both the executive and the overseer have private information as to the correct policy to pursue, and both are motivated by the desire to appear competent. A partisan overseer is one who, in addition to seeking to promote her own reputation, cares how her decision will impact the executive's reputation. Our main result is that partisanship can improve the efficacy of an oversight regime, as the distortions caused by a partisan overseer's desire to affect the executive's reputation can offset the distortions caused by her desire to enhance her own. Our results provide a new rationale for divided government, as partisan considerations are often necessary to prevent the overseer from rubber stamping all executive proposals. 相似文献

Car ownership is generally considered an important variable in car travel behaviour research, but its specific role is often not well understood. Certain empirical studies consider car ownership as the dependent variable explained by the built environment, whereas other studies deem it to be one of the independent variables explaining car travel behaviour. This paper takes note of the dual influence car ownership has in explaining car travel behaviour by assuming that car ownership mediates the relationship between the built environment and car use. The relationship is estimated using a structural equation model since it accounts for mediating variables. This approach confirms the intermediary nature of car ownership. 相似文献
