The implementation mechanisms of voluntary food safety systems   总被引:1,自引:0,他引:1  
The recent food scares have been the motivation for voluntary programmes on food safety being promoted by public authorities and voluntarily implemented by food operators. In this article, we take into account the nature of the contamination risk to investigate the complementarities between private and public mechanisms for those voluntary systems to be implemented by a firm. We show two main results. First, when the firm directly markets its products to consumers a strong mandatory threat is a sufficient condition to implement voluntary systems whatever the risk of contamination. In contrast, when the mandatory threat is weak voluntary systems should be more implemented in industries where the risk of food contamination is low (pesticide residue) than in industries where the risk of contamination is high (pathogenic contamination). Second, when the risk of food contamination is low and the firm is embedded in a supply chain where the retailer can impose its own safety system, a well-designed penalty contract will induce a voluntary implementation whatever the mandatory threat.  相似文献

In recent decades, policies in many countries have been shaped by the implementation of economic liberalization, characterized by state withdrawal from marketing operations and control of trade. In this era of liberalization, policies regulating commodity marketing and trade were expected to disappear, but, in fact, this has hardly occurred. A comparative study is carried out of three farm sectors in Costa Rica, based on a dynamic analysis of behaviour in the context of the institutional change brought about by liberalization. The capacity of farmers' organizations to adapt and contribute to institutional change through their control over economic activity and their participation in policymaking processes is highlighted. In so doing, it is shown that, even in a liberalized era, policies regulating marketing and trade still exist and affect the functioning of agricultural markets. These policies differ according to the farm sector and can be linked directly to the influence of farmers' organizations within these sectors. It is shown that organizations play a key role in the regulation of farm sectors, and that their success depends on the institutional and organizational “thickness” to which they have contributed in each sector. Differences in historical trajectories can explain differences in the capacity of organizations to influence policymaking and to gain market share.  相似文献

Understanding the capacity of agricultural systems to feed the world population under climate change requires projecting future food demand. This article reviews demand modeling approaches from 10 global economic models participating in the Agricultural Model Intercomparison and Improvement Project (AgMIP). We compare food demand projections in 2050 for various regions and agricultural products under harmonized scenarios of socioeconomic development, climate change, and bioenergy expansion. In the reference scenario (SSP2), food demand increases by 59–98% between 2005 and 2050, slightly higher than the most recent FAO projection of 54% from 2005/2007. The range of results is large, in particular for animal calories (between 61% and 144%), caused by differences in demand systems specifications, and in income and price elasticities. The results are more sensitive to socioeconomic assumptions than to climate change or bioenergy scenarios. When considering a world with higher population and lower economic growth (SSP3), consumption per capita drops on average by 9% for crops and 18% for livestock. The maximum effect of climate change on calorie availability is ?6% at the global level, and the effect of biofuel production on calorie availability is even smaller.  相似文献

Recent studies call for reconsideration of the predictions of resource dependence theory, in light of contemporary industrial and economic environments. This study accordingly investigates the influence of dependence on the strategic choice to innovate by focusing on a rarely studied topic, namely, the sources of dependence. In studying small and medium‐sized video game enterprises, this paper provides empirical validation of dependence phenomena. These companies have limited resources, which inevitably creates dependence, exacerbated in innovative contexts because of the prevalence of negative effects, such as opportunism, abuse of power, limited innovation, or inequitable distributions of economic value. To deal with these negative effects, some enterprises use cooperation or integration strategies to try to minimize their dependence. The strategic choice then might be conditioned. The results of a comparative and qualitative study of five video game developers show that a lack of resources and skills is the primary source of dependence. In addition, a hierarchy of sources of dependence seems to guide the strategic choices of developers to innovate.  相似文献

The controversy over the theoretical validity of the ‘Coase theorem’ is closely linked to the controversy over the correct statement of it, since the principal need is to determine what valid generalizations can be made on the basis of Coase’s 1960 Coase, R. H. 1960. “The Problem of Social Cost.” Journal of Law and Economics 3:144.[Crossref], [Web of Science ®] [Google Scholar] examples. The present article does not aim to review the content of the controversy as such, but rather to question the reasons behind it: why so much noise about a proposition that is patently unrealistic (because of its assumption of zero transaction costs)? I argue that the prominence of the controversy, namely of the question of the validity (and statement) of the ‘Coase theorem’, can be analytically explained by the roles this ‘theorem’ plays in microeconomics: it is critical (of the standard theory of market failures), heuristic (drawing out the consequences of the efficiency assumption), and normative (conveying an optimistic view of the efficiency of exchange). I stress that these roles depend on the nature of the exchange defined in the formulation of the ‘theorem’. And I conclude that they rest upon the cooperative bargaining version, and therefore on an optimistic belief in the ability of people to find efficient agreements.  相似文献

We explore the relationship between development policies, finance and growth as approached by New Structural Economics (NSE) with special reference to Transition Economies (TEs). On a sample of 164 economies for 1963–2009, our analysis confirms NSE propositions that the type of development policies, as captured by the Technology Choice Index (TCI), has a significant effect on long-term growth. However, this differs for TEs as a whole and its subgroups. Further to this, using a sample of 94 countries for 1985–2009, we provide a first empirical test of the relationship between growth, TCI and financial structure distortions and we show that there is a negative relationship between financial distortions and TCI on the one hand and medium-term growth on the other hand. We also find that the negative effect of a higher ratio of TCI on medium-term growth is partly mitigated, although not eliminated, by moderate level of financial sector distortions. This points towards some positive externalities of simultaneous financial and industrial sector distortions, at least in the medium run. However, TEs are shown to differ from the rest of the sample as financial distortions play a more pronounced direct negative effect on medium-term growth in these countries.  相似文献

Recent studies assessing plausible futures for agricultural markets and global food security have had contradictory outcomes. To advance our understanding of the sources of the differences, 10 global economic models that produce long‐term scenarios were asked to compare a reference scenario with alternate socioeconomic, climate change, and bioenergy scenarios using a common set of key drivers. Several key conclusions emerge from this exercise: First, for a comparison of scenario results to be meaningful, a careful analysis of the interpretation of the relevant model variables is essential. For instance, the use of “real world commodity prices” differs widely across models, and comparing the prices without accounting for their different meanings can lead to misleading results. Second, results suggest that, once some key assumptions are harmonized, the variability in general trends across models declines but remains important. For example, given the common assumptions of the reference scenario, models show average annual rates of changes of real global producer prices for agricultural products on average ranging between ?0.4% and +0.7% between the 2005 base year and 2050. This compares to an average decline of real agricultural prices of 4% p.a. between the 1960s and the 2000s. Several other common trends are shown, for example, relating to key global growth areas for agricultural production and consumption. Third, differences in basic model parameters such as income and price elasticities, sometimes hidden in the way market behavior is modeled, result in significant differences in the details. Fourth, the analysis shows that agro‐economic modelers aiming to inform the agricultural and development policy debate require better data and analysis on both economic behavior and biophysical drivers. More interdisciplinary modeling efforts are required to cross‐fertilize analyses at different scales.  相似文献

In the last decade, the concept of co-regulation has been developed and increasingly promoted as an important instrument of regulation. In the context of food safety, we examine co-regulation programs from the point of view of an enforcement agency. We develop a conceptual framework of enforcement of food safety regulation for use in assessing the degree of shift toward co-regulation from traditional approaches and apply it to a case study of the French import market for produce at Perpignan. We find that co-regulation in the enforcement of pesticide residue limits resulted in a change of practices for the regulatory agency from punishment to prevention based on incentives and information programs.  相似文献

Engaging in unethical consumption behaviors is an acute societal problem that can have severe consequences for adolescents, and businesses in particular have been accused of making such consumption particularly appealing and accessible. However, the causes of unethical behaviors are not well understood and research on the causes has been mixed. In this research, we investigate the effects of coping strategies for loneliness on adolescents’ adoption of unethical behaviors, a topic that business ethics research has not explored. In a large-scale study (n = 409) of adolescents (ages 13–17), we show that whether loneliness leads to the adoption of unethical behaviors depends on the strategies adolescents use to cope with their loneliness: active coping strategies are associated with fewer unethical behaviors, whereas passive coping strategies are associated with more unethical behaviors. In addition, we show that active and passive coping strategies can be executed through consumption practices. We show that the relation between active coping and fewer unethical behaviors is mediated by sharing of possessions, whereas the relation between passive coping strategies and more unethical behaviors is mediated by product acquisition. Finally, we also show that these mediated relations differ as a function of age cohort (grade level). The indirect effect of active coping on fewer unethical behaviors via sharing holds only for middle school adolescents, whereas the indirect effect of passive coping on more unethical behaviors via product acquisition holds only for high school adolescents. We shed new light on both the bright and dark sides of materialism and unethical behaviors and provide practical implications for research on loneliness, business ethics, and unethical behaviors.  相似文献

This article examines the effects of war on livelihood choices and welfare outcomes of rural households in Kosovo using the 2000 Kosovo Living Standards Measurement Survey. We analyse the extent of the legacy of war on livelihood activities and welfare. We first identify livelihood portfolio clusters of households pursuing similar combinations of activities. These clusters are comparable to those described in more qualitative studies in the immediate post‐conflict period. We then examine the determinants of livelihood portfolio choice and the consequences of these for welfare outcomes. Our results provide evidence of a relationship between a household’s experience of war and livelihood choice. We also identify significant selection effects on welfare for three out of four livelihood clusters, highlighting the fact that selecting into a specific livelihood portfolio changes welfare relative to expected levels. Our results show that war not only affects livelihood choices but also changes the returns to these activities.  相似文献
