One of the cornerstones of the National Program for Control and Eradication of Bovine Brucellosis and Tuberculosis in Brazil is the voluntary accreditation of free herds. We developed a stochastic cost–benefit analysis model for two types of dairy herds (high yield Holstein‐Zebu crossbred females and lower productivity smaller scale herds) to identify the technical and economic constraints of this process. The initial prevalence of infected animals and the impact of the disease in the structure and performance of the herd were derived from secondary data. Information on the costs and benefits of herd sanitation were compiled into a cost–benefit model at the herd level. The last step consisted of a scenario simulation to evaluate the impact of alternative policies to the certification process. For each scenario, we calculate the probability over time of a Benefit–Cost Ratio greater than 1 and of an Internal Rate of Return above 1% (the discount rate used in the model). Results show that larger and more intensive dairy farms, and also herds affected by brucellosis compared with tuberculosis‐positive herds, are more likely to achieve financial gains from the certification investment. The compensation for culled animals is important in the initial phase of herd sanitation and the premium payment on milk would help farmers to achieve a return on the investment over time. The model can be adapted to different and dynamic production, epidemiological and economic settings.  相似文献

Cause‐related marketing (CRM) refers to the phenomenon where brands partner with causes, such as nonprofit organizations. Consumers may see some CRM partnerships as less compatible than others, however the level of perceived compatibility differs from one consumer to another. We know a great deal about how perceptions of compatibility affect attitude and behavior toward CRM partnerships, but we know less about how to predict a consumer's perception of compatibility. Therefore, our purpose was to investigate the boundaries in which balance theory could be used to make predictions about consumers’ responses to CRM partnerships. This is the first study to consider the construct of attitude strength (vs. attitude alone) when considering balance theory. We found that a consumer's attitude toward a brand, along with their attitude toward a cause, predicts their perceptions of CRM compatibility. We also found that CRM triadic balance could be predicted when attitude strength was included in the models, and that balance theory allowed us to observe preliminary evidence of attitude and attitude strength spillover effects in CRM triads. Practitioners can use these insights to determine which organizations to partner with, as well as determine how advertising these partnerships may affect acceptance of these partnerships.  相似文献

Marisol has forged a successful legacy in Brazil in the market for clothes with a sophisticated, stylish look. Success in Brazil enabled the firm to garner overseas customers. The establishment of subsidiaries in Argentina, Italy and Mexico, as well as sales operations in several countries – including Chile, Colombia, Spain, and the USA, among others – represented important steps in Marisol's internationalization. Marisol's executives have to decide on several issues: how to consolidate their position in the USA market and in other countries? What modes of operation – own stores, franchisees, multi-brand stores, private label supply – to use in which countries? Which brands to launch abroad and whether to adapt them to local tastes, while exploiting the image of Brazilianness?  相似文献

This study examines sport coaches’ perceptions about their experiences abroad. Coaches are part of a diverse new set of mobilities occurring in the sport labour market. However, few authors explored the individual cases of coaches’ migration. Here, we examine coaches’ recruitment process, motivations to migrate and their experiences abroad. Participants were five migrant coaches chosen through purposive sampling to achieve a pool of deep and rich data regarding the research topic. Data was collected using semi-structured interview questionnaires. For the exploration and analysis of the qualitative data, we used MAXQDA 11 software package. The results showed that all coaches migrated through an informal mechanism of recruitment which relied on their networks. Their discourse suggested they fit three types of migration referred in the literature: ambitionist, cosmopolitan and pioneer. Their experiences abroad were mainly related to their professional career and adaptation. All coaches reported that their experience was positive and they recommend that other coaches migrate as well. These results are important for the understanding of sport migration not least because coaches are at the core of the migration process of various stakeholders.  相似文献

International Business (IB) theories encompass economic approaches, where firms use objective criteria to select foreign markets, and behavioral approaches, where firms use psychic distance. This study proposes new objective criteria to measure psychic distance and adopts multiple linear regressions with a foreign-trade econometric model adapted to address psychic distance and market size and their relationships with Brazilian exports over 10 years. Psychic distance showed a close relationship to exports from smaller firms, while the market size of the destination country was always significant. This brought original empirical evidence to the validity of IB theories as well as to the exports behavior of firms from emerging economies.  相似文献

This paper uses the stochastic approach to convergence to investigate whether real per capita GDP in Portugal has been converging to the EU15 average. The estimation accounts for conditional convergence, transitional dynamics and up to two structural breaks. It is found that per capita GDP in Portugal has indeed converged to the EU15 average, but the pace of convergence has not been uniform along time. In particular, a slow down in the convergence process is identified in 1974. This result depends, however, as to whether the choice of this break-date is viewed as uncorrelated with the data. No evidence of acceleration in the speed of convergence is found after EC accession, in 1986.An earlier version of this paper was presented at the Fifty-Ninth International Atlantic Economic Conference, London, England, March 9–13, 2005. Helpful suggestions from the conference participants and Luis Catela Nunes are acknowledged. The author expresses his gratitude for the financial support of the Portuguese Foundation for Science and Technology (FCT), under research grant POCI/EGE/55423/2004 (partially funded by FEDER).  相似文献

In this research the authors examine whether counterfactual thinking, the process of imagining alternatives to reality, can have a detrimental impact on consumers' feelings. Five studies examine the dysfunctional role of counterfactual thinking in the presence of Minimum Purchase Requirement conditional message framing (“X% off all purchases if you spend at least $Y”), and its affective consequences. Results show that the presence or absence of the minimum amount restriction (Studies 1A and 1B), success or failure to meet the restriction (Studies 2A and 2B), and perceived closeness (i.e., outcome proximity) to success or failure in meeting the restriction (Study 3), drastically influence consumer affect to the extent that participants receiving an inferior deal exhibited higher satisfaction than those receiving a superior deal. It is suggested that such promotion‐induced counterfactual thinking polarizes consumer satisfaction, which may impede consumers from arriving at optimal conclusions. © 2010 Wiley Periodicals, Inc.  相似文献

This paper extends previous analysis of the choice between internal and external R&D to consider the effect of this decision on productivity. Existing empirical research confirms that there is a positive relationship between technological assets and firm performance. However, few works have attempted to identify whether the technological sourcing decision taken by the firm affects productivity. The main finding of this paper is that the technological strategy developed by the firm does affect productivity. This issue is particularly novel as it incorporates the technological sourcing decision taken by the firm. The results we obtain indicate that the technological sourcing decision affects the relationship between technological capital and productivity. Thus, our findings suggest that the decision between internal and external R&D matters.  相似文献

The principal–agent theory asserts that public firms' performance is driven by efficient capital and labor markets but is silent about non‐listed private companies, which are less permeable to market forces (both capital and labor) than are public companies. We propose and test a 2 × 2 framework distinguishing owner‐controlled vs. agent‐led firms from firms with a flat vs. multilayer organization. Our findings provide highly contrasted results and raise important issues for further study of private firms. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献
