Crop management,labour organization,and marketing: three key issues for improving sustainability in organic vegetable farming

Most market-garden farms that have converted to organic farming (OF) in the last few decades in France are small and diversified. Larger farms usually specialize in a few vegetable species and frequently face technical and economic problems when they convert to organics. Diversifying production may be a means of increasing sustainability due to larger crop rotations and varied marketing outlets, but it has various implications on farm management, especially labour organization and marketing. In the present study, we examined how an acceptable degree of species diversification can act as a lever to develop organic vegetable production by combining sociologist and agronomist points of view. Multidisciplinary surveys of 30 market-garden farms varying in usable surface area and degrees of crop diversification were carried out. Consequences on crop management, labour organization and skills, and marketing implications were described, and farm sustainability was assessed. Specialized farms of the sample had a rather industrial organization of labour and marketing and benefited from economy of scale to produce vegetables. But in the long term, they may suffer from low agronomical sustainability because of narrow crop rotations and intensive crop management. Diversified farms were more sustainable according the criteria studied, but they suffered from the extremely complex management of cropping systems. These results are discussed on both the farm and territorial levels. Collective marketing initiatives and social networks might help reach an acceptable degree of species diversification at the farm level. Potential innovative organizations are identified, which could facilitate the transition to OF.     

Inequality in Europe: What can be done? What should be done?

As economic inequality in Europe has continued to rise, it has become the subject of increasing academic attention. What are the drivers of inequality? How does it affect intergenerational economic and social mobility? At what point does inequality become a drag on economic growth or a threat to social order? What economic policy tools are available to reduce inequality? This Forum addresses these and other aspects of this complex and disturbing trend. Case studies of Ireland, Germany and Spain also highlight the impact of economic inequality on individual member states.     

A Meta-Analysis into Multiscreening and Advertising Effectiveness: Direct Effects,Moderators, and Underlying Mechanisms

Using another media screen while watching television has become a part of people’s daily routines. The topic of multiscreening has thus received increased attention from advertising scholars in recent years. To gain a better theoretical understanding of the circumstances under which multiscreening effects occur and to offer practical guidelines to advertisers, the current study synthesizes the results of past studies on multiscreening and advertising and examines the direct effects of multiscreening on both cognitive and affective advertising outcomes, the possible moderators of those effects, and the underlying mechanisms of multiscreening with regard to advertising outcomes. The results indicate a negative direct effect of multiscreening on cognitive outcomes. The effect is weakened, however, by factors related to research, advertising, and media. In addition, the results show no direct or total effect of multiscreening on affective advertising outcomes, but this again depends on various media-, advertising-, and research-related factors. Finally, the results show that attention, enjoyment, and resistance constitute the underlying mechanisms that explain the effect of multiscreening on memory and persuasion.     

The propensity to hedge using futures contracts: the case of potato futures contracts

This paper studies why UK non-financial firms hedge with potato futures contracts. It is found that the financial characteristics of firms in the sample play an important role in influencing the propensity to hedge. For example, it is found that firms that hedge are on average larger than firms that do not hedge. Firms that hedge also have more volatile earnings. Furthermore, firms that do hedge appear to want to smooth earnings to reduce the costs of financial distress and avoid entering the highest tax threshold.     

International Integration and Growth: A Further Investigation on Developing Countries

The paper examines empirically the linkages between international integration and economic growth in a panel of 47 developing countries and 18 trade blocs over the period 1970–1989. Specifically, it attempts to identify through which channel(s) – notably, specialization according to comparative advantage and increased efficiency, exploitation of increasing returns from larger market, and technology spillovers through investment and trade–trade blocs can affect the economic growth of their member countries. The results suggest that (1) intra-bloc trade does not affect growth significantly; (2) income diversion among member countries contributes positively and significantly to growth; and (3) the size of the trade bloc does matter in the sense that the bigger is not always the better for the welfare of the member countries.     

Sustainable Development and the Consumer: Exploring the Role of Carbon Labelling in Retail Supply Chains

This empirical article contributes to the sustainable development debate by examining consumer responses to carbon labels within a real world context. Given the limitations of methodologies that use self‐reported or intended measures of purchasing behaviour, we use the loyalty card data of the largest supermarket retailer in the UK to measure the impact of carbon labels on sales by different consumer segments. The data show that the trial of carbon labels on supermarket own brand products has had no discernible impact on shifting demand to lower carbon products. In order to explore possible reasons for lack of impact, nine focus groups were held using purposive sampling by retailer consumer segments to allow an exploration of awareness, understanding and use of carbon labels. The findings from the focus groups identified possible reasons for this lack of impact: lack of awareness and understanding of carbon labelling; constraining or facilitating social and cultural influences; and the heterogeneous nature of consumers. As a result, a number of implications for stakeholders are discussed. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.     

A Note on the Identification of Dynamic Economic Models with Generalized Shock Processes

Dynamic stochastic general equilibrium (DSGE) models with generalized shock processes, such as shock processes which follow a vector autoregression (VAR), have been an active area of research in recent years. Unfortunately, the structural parameters governing DSGE models are not identified when the driving process behind the model follows an unrestricted VAR. This finding implies that parameter estimates derived from recent attempts to estimate DSGE models with generalized driving processes should be treated with caution, and that there always exists a tradeoff between identification and the risk of model misspecification. However, these results also make it easier to address the issue of model misspecification by making it computationally easier to check the validity of cross‐equation restrictions.     

Rousseau's notion of envy: A comparison with modern economic theory

Abstract

The concept of envy is present both in Rousseau's economic philosophy and in modern economic theory. This paper compares these different uses of the concept and studies the relevance of the definition of envy adopted on each side, taking into account what is at stake when a notion of envy is introduced. It will be shown that Rousseau's envy cannot be expressed by modern conceptions of envy. Nevertheless, it enlightens the debate between the two competing notions of envy present in modern economic theory, revealing that the existence of envy questions the notion of self-interest.
