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.     

The effect of pro-environmental attitudes and eco-labelling information on green purchasing decisions in Australia

The main purpose of this study is to measure the effects of pro-environmental attitudes, knowledge, and eco-labeling information on green purchasing decisions. Data were collected from 400 undergraduate students studying at an Australian University. The findings suggest that pro-environmental attitude and eco-labeling information significantly affect green purchasing decisions. Eco-labeling, however, plays a more significant role in influencing green purchasing decisions. Finally, implications and suggestions for future research are discussed.

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.
