Although overall linkages are steadily increasing in growth processes, em-pirical data supply strong evidence of large intercountry and intertemporal fluctuations of the domestic-to-overall linkages ratio. This paper tries to explain this phenomenon by modelling a producers' behaviour which appears more realistic than that usually assumed in interindustry or computable general equilibrium models. The main novelty of the results is that the same causes that generate interindustry multipliers can also ‘trap’ domestic linkages into reinforcing (‘virtuous’) or weakening (‘vicious’) circles, depending on whether the price competitiveness of domestic activities is above or below a threshold related to the non-price competitiveness of those activities. These results can help to explain the fluctuations of domestic linkages with respect to overall linkages by spatial and temporal shifts of the threshold between the vicious and the virtuous ‘areas’. Moreover, they emphasize the importance of supply policies-mainly R&D policies—because of their ‘pushing down’ effect on this threshold. 相似文献

Introducing locally negatively interdependent preferences into a simple AK growth model easily explains the often observed insignificant or positive correlation between distortionary redistribution and growth rates. Positive capital income taxes and lump sum transfers are harmful for growth, but people rationally vote for them in order to reduce “rat race” overaccumulation. A “neutrality proposition” holds if the pivotal voter is the mean voter, as in a representative agent case, but it fails if the pivotal voter is poorer than the average citizen. 相似文献

In Belgium as in many other countries, agricultural land is under pressure for development of other land uses. This paper presents a method for setting priorities for preservation of land for agriculture. The method is based on a participatory approach through which a value tree is formulated. This results in a list of criteria to define farmland value, which is explicitly linked to the objectives for farmland preservation. The value tree allows the list of criteria to be determined in a structured and consistent way. The participatory process contributes to the development of a shared vision on farmland preservation. The approach also incorporates context specificity, as shown by its application for farmland preservation in Flanders. 相似文献

Farmland for tomorrow in densely populated areas 总被引:1,自引:0,他引:1

The paper describes the results of a research that aimed to come up with a well structured method to estimate future farmland requirements in densely populated areas. By using in depth interviews, scenario analysis and strategic orientation rounds, a method is developed to support policy optimization and to explore alternative future developments. The method is applied to the case of agriculture in the Flemish part of Belgium to show the feasibility of the model and to provide input for the discussion among policy makers in Flanders. The research results can be used by policy makers to build a new Spatial Plan Flanders for the period 2007–2013. 相似文献

Farmers in sub‐Saharan Africa are constrained by large transaction costs associated with marketing of their livestock. However, transaction costs are often not taken into account in the analysis of factors hampering the development of livestock marketing in this region. This article empirically measures the influence of transaction costs on the offtake from cattle grazed on natural rangelands in Uganda. The study is based on the monitoring of 696 cattle transactions in three districts of Uganda from August 2004 to August 2005. The estimated models suggest that proportional transaction costs represented by the state of roads, distance to markets, and time taken to reach the market are important variables constraining market participation. In order to raise offtake from the national herd, it is essential to explicitly address these costs. One potential solution is collective action in marketing of livestock in which proportional and fixed transaction costs are reduced and shared among the group members. 相似文献

Since the beginning of the consumer crisis, which in Italy can be traced back to the second half of 2008, there has been a significant development of store brands? market share which has reached close to 25% in some leader groups (for example Coop, Conad, Esselunga). The acceleration of the rate of penetration of store brands differs by category and store format. The main reason for this result is the different consumer purchase behavior. In this framework, this work aims at analyzing the elements that have determined the store brands success in the main store format (hypermarket, supermarket, convenience store), through analysis of single retail mix levers management. The factors that have mostly influenced the growth in store brands, in each store format, are investigated throughout a complete informative retail database. The aim of this study is to verify whether the management of the individual retail mix levers produces the same results in different store formats. Additional enhancement to the understanding of store brands management and further support to modern distribution management policies are also provided. A relevant finding is that the performance of store formats depends on the use of specific retail mix levers. 相似文献

In this paper we study a particular case of “multiple” externalities associated to the production of a good/activity, whose
external effects can change from positive to negative depending on the level of output (intersecting externalities). To analyze their impact on the public policy we propose a very simple two-agent partial equilibrium model in the technological
context of externalities. In a static framework, the centralized solution always implies an optimal policy, which may consist
of taxation or subsidization depending on the individual optimum and on the technology parameters. In a dynamic model with
local knowledge of the efficiency function and instantaneous output adjustments, such an optimal policy can be structurally
stable or unstable. In the latter case, under small changes of the parameters the policy may switch from low taxation/subsidization
to high taxation/subsidization or vice versa, or even jump discontinuously from taxation to subsidization or vice versa. Furthermore, the decentralized solution based upon “tradable rights” can be economically equivalent to the centralized solution
in the form of taxation policy but the two solutions may be not politically equivalent.

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
