In an infinite-horizon stochastic model, a coup not only disciplines a dictator's policy towards a group of “kingmakers”, but also enables a kingmaker to become a dictator. Greater competition for the dictator's position, a lower impact of the dictator's policy on the kingmakers, or lower risks of staging a coup raises the benefit of a coup relative to its opportunity cost and so raises the probability of a coup. Since periodic shocks affect the efficacy of the dictator's policy, a bad enough shock makes it too costly for even talented dictators to avert a coup. More talented dictators are able to survive more negative shocks, so the worst shock in a dictator's reign is informative about the probability of a coup. Conditional on the worst shock, the probability of a coup is independent of a dictator's duration in office. The unconditional probability declines with duration.  相似文献

Using Remote Sensing for Agricultural Statistics   总被引:7,自引:0,他引:7  
Remote sensing can be a valuable tool for agricultural statistics when area frames or multiple frames are used. At the design level, remote sensing typically helps in the definition of sampling units and the stratification, but can also be exploited to optimise the sample allocation and size of sampling units. At the estimator level, classified satellite images are generally used as auxiliary variables in a regression estimator or for estimators based on confusion matrixes. The most often used satellite images are LANDSAT-TM and SPOT-XS. In general, classified or photo-interpreted images should not be directly used to estimate crop areas because the proportion of pixels classified into the specific crop is often strongly biased. Vegetation indexes computed from satellite images can give in some cases a good indication of the potential crop yield.  相似文献

Synthetic indicators are intended to provide an overview of the situation of individuals in a community in relation to a concept to be studied such as quality of life. This study aims to propose a territorial measure and classification of education and child health for countries of the Horn of Africa based on the criteria set out in the United Nations Declaration of the Millennium Development Goals. We construct a synthetic indicator from a multidimensional approach taking into account a large number of variables defined in the Millennium Declaration. For this purpose, we use the Pena distance method for the year 2010, which is the latest year for which data is available. We believe that the situation of the countries in the Horn of Africa differ with respect to the Millennium Development Goal indicators for education and child health. The most striking differences relate to basic quality of life variables.  相似文献

This article presents the decisions that are presented in the transition from theoretical to methodological, as a means to establish coherence and validity in an investigation that addresses strategic design’s contribution to organizational transformations. A coherent methodological proposal is presented between the ontological posture (intersubjectivity), epistemological posture (pragmatism), and research method (mixed) required to address the object of research in strategic design, and to consistently select the various techniques and procedures required. This proposal is pertinent to respond to the research question of what the role fo strategic design might be, as related to organizational transformation, to the extent that it provides competencies (human capital), processes (structural capital), and a relationship model (relational capital).

Despite the growth in the number of consumer boycotts, the marketing literature has paid little attention to the factors that could explain such behavior or the effect of boycotts on entrepreneurial initiatives. Several studies have examined the motivations of customer boycott behavior. Nevertheless, its relation to other attitudinal variables and with firm-related characteristics has not been analyzed or has been dealt with only partially even though the implications are crucial for incumbents and start-ups to adapt their strategies. This paper examines the factors that could explain the consumer’s decision to boycott a brand because of its location in a specific country. The relevance of addressing this gap is based on the boycotts’ impact on local firms and start-ups performance. This study addresses this issue by proposing a model that considers consumer-related variables and the perceived importance of brands. The hypotheses proposed in this research are verified via variance-based partial least squares structural equation modeling. The authors tested their framework during an actual boycott to Catalonian products and firms promoted on social media in Spain. The discussion of the results and their implications contribute to improving entrepreneurs, managers and academics’ comprehension of the determinants of customers’ intentions to participate in a boycott. This can also provide entrepreneurs and managers with a guide to orientate the design and implementation of strategies that enable the reduction of customer abandonment due to political boycotts. The main value of this research is that it provides a comprehensive model that includes different sorts of variables that could be involved in consumer boycott behavior. This model can support flexible entrepreneurial and managerial practices to help entrepreneurs to adapt rapidly to changes in the market due to boycotts.

This paper studies the relationship among Italian, Spanish and United Kingdom prices over the period 1874–1998, for most of which the currencies of these three countries maintained a floating exchange rate regime. By using cointegration techniques with broken linear trends, we find a single vector for the period 1874–1935 and two vectors and, consequently, a single common trend for the period 1940–1998. Therefore, this paper provides new evidence of no long-run monetary independence under floating regimes. Furthermore, the price differential dynamics captured by deterministic trends in the period 1940–1998, as well as agreeing with the evidence of long-run transmission of interest rates in the floating post-Bretton Woods era, fit in perfectly with the new de facto taxonomies on exchange rates.  相似文献

The aims of the present work centre on determining whether co-created value constitutes a competitive advantage for firms, and whether it is capable of influencing consumer behaviour. Applying the service-dominant logic perspective, the work examines the firm's capabilities in the context of its business-to-customer (B2C) interactions, focusing on information and communications technology (ICT) as a particular driver of value co-creation. Taking this B2C perspective, ICT is measured, from the firm's point of view, and customer perceptions are analysed, using the variables ‘value co-creation’, ‘perceived value’ and ‘loyalty’. The sample consists of 100 service firms and 572 of their customers. The findings indicate that ICT capabilities have a direct effect on value co-creation, as does value co-creation on perceived value and loyalty.  相似文献

Many firms attempt to develop market‐oriented attitudes and behaviors because of their presumably positive consequences for performance. A market orientation can provide the cultural basis for successful differentiation strategies focused on customer satisfaction. However, inconclusive evidence regarding the relationship between market orientation and performance demands an analysis of possible moderators. This paper therefore analyzes the moderating role of environmental characteristics in the market orientation–performance relationship. Heterogeneous methodologies and measures could explain some diversity in empirical results. Moreover, both the market orientation–performance relationship and the moderating effects of environment dynamism, turbulence, hostility, and complexity may depend on more general characteristics of the environment. A complete diagnostic of the moderating effect of the environment must analyze phenomena in different socioeconomic and political–regulatory contexts. Therefore, the authors (1) analyze the moderating role of environmental dynamism and competitive intensity; (2) consider a broad range of performance measures, distinguished as effectiveness, efficiency, and adaptability measures and as financial and operational measures; and (3) focus on a priority 1 region of the European Union, characterized by small and medium‐sized enterprises that face a global competitive scenario from a disadvantaged local environment. The empirical results support the positive relationship between market orientation and performance and indicate the relationship is inhibited by competitive intensity, which contrasts with existing arguments and empirical results.  相似文献

The main aim of this study is to contribute to the debate on the effects of a common currency. In particular, the impact of a common currency on growth via trade and tourism is explored for a panel dataset which includes 179 countries as destination and 30 OECD countries as origin over the period 1995–2006. This research contributes to previous work in three ways: (i) tourism is included as an additional channel for a common currency to promote growth; (ii) the heterogeneity of countries is addressed by dividing the sample into three groups of countries by income; and (iii) up‐to‐date data including the case of the euro are considered. The results obtained suggest that a common currency strengthens economic growth by promoting not only international trade but also tourism.  相似文献
