De la banque de données AGRITEL, 336 fermes conventionnelles et 16 fermes biologiques, spécialisées en production laitière, sont sélectionnées. Sept groupes (dont un est biologique) sont alors formés correspondant à des concepts de production différents. Les groupes defermes conventionnelles correspondent à des niveaux d'intrants particulièment élevés (haut niveau d'intrants) ou faibles (bas niveau d'intrants), ainsi qu'à des niveaux de production élevés @roduction intensive) oufaibles (production extensive), pour le troupeau ou pour l'ensemble de l'entreprise.
Les fermes biologiques parviennent à des résultats technico-économiques et financiers au moins aussi bons que les fermes avec des rendements élevés (intensifs). En revanche, même si les concepts de production sont proches, les différences de rendement et de rentabilité sont assez nettes (souvent signcatives) entre le groupe biologique et les groupes extensifs ou à bas niveau d'intrants. Les entreprises biologiques sont plus équilibrtés et la prédominance de la production laitière est moindre. Les coûts de main-d'œuvre sont toutefois plus élevés que la plupart des groupes d'entreprises conventionnelles.
Cette étuaè nous laisse croire qu'il est possible d'amtéliorer la rentabilité des fermes extensives et à bas niveau d'intrants, dont les concepts de production se rapprochent de ceux de l'agriculture biologique. 相似文献

In this paper, I conduct a correspondence testing experiment to examine sexual orientation discrimination against lesbians in Germany. I sent applications from four fictional female characters in response to job advertisements in Munich and Berlin: a heterosexual single, a married heterosexual, a single lesbian, and a lesbian who is in a “same‐sex registered partnership.” While single lesbians and lesbians in a registered partnership are equally discriminated in comparison to the heterosexual women in the city of Munich, I found no discrimination based on sexual orientation in Berlin. Furthermore, for a subset of the data we can compare the effects of a randomized versus a paired testing approach, which suggests that under certain conditions, due to increased conspicuity, the paired testing approach may lead to biased results. 相似文献

We study the reasons for differences in welfare benefit receipt between immigrants and natives in 16 EU countries using Oaxaca‐Blinder decompositions of a Heckman model. Differences in welfare benefit receipt diminish or disappear altogether after controlling for differences in characteristics of the two groups. The largest part of this is explained by differences in benefit take‐up rather than benefit levels conditional on benefit receipt. The characteristics contributing most to native–immigrant welfare wedges in contributory benefits are differences in age. For non‐contributory benefits, differences in household size and composition are most important. Overall results thus suggest a limited capability of selective immigration policies to reduce welfare benefit receipt among immigrants. 相似文献

A time-varying natural rate of interest is estimated for the euro area using a multivariate unobserved components model. The problem of aggregating interest rate data for the pre-EMU period is directly addressed, and a simple method is proposed in order to adjust the risk premia in the interest rate data prior to 1999. We show that, for the pre-EMU period, using risk-unadjusted policy rates leads to periods of high risk premia being erroneously taken as monetary policy replies to the output gap; in contrast, using risk-adjusted policy rates yields an estimate of the reaction of monetary policy to the output gap corresponding approximately to an increase of 40 basis points for a 1%positive deviation of output from potential output. A positive deviation of inflation from its trend of 1%is estimated to have triggered an approximately 1.2%increase in short-term interest rates. 相似文献

In the food sector, retailers often present themselves as guardians of consumer interests, with superior efficiency and effectiveness in the governance of food, in relation to public actors. Concerns about retail governance institutions, such as private standards or Corporate Social Responsibility (CSR), mainly emphasise a lack of input legitimacy, that is legitimacy relying on democratic procedures. Less often concerns are raised regarding output legitimacy, that is legitimacy based on the effectiveness of retail governance institutions. Based on concepts of discursive power, this paper explores how retail corporations establish their claim to legitimacy in food governance via concepts of output legitimacy. The paper pursues its aim by performing a critical discourse analysis of retailers' discursive strategies identified here as imperialist, recursive, symbiotic and ironic. 相似文献

We investigated the mediating role of financial inclusion in the relationship between financial literacy and financial well-being in Ghana. Using PLS-SEM, we found that financial inclusion indeed mediates financial literacy and financial well-being in Ghana. We also documented a positive and significant relationship between Ghanaians' financial literacy and financial well-being. Again, financial literacy has a direct positive effect on financial inclusion. Hence, to enhance the impact of financial literacy on financial well-being in Ghana, policymakers should grant financial institutions enough freedom to offer a variety of financial services; financial institutions that have lost credibility in Ghana (such as insurance companies) should be put in check to build the trust of Ghanaians in them; and the cost of using a mobile phone and internet services to access financial services in Ghana should be reduced. The management of financial institutions can utilize the freedom offered to them by policymakers to offer various financial services to the public, build trust in customers, and offer lower-cost services to help improve the financial well-being of Ghanaians. 相似文献

In this paper we develop a conceptual framework, based on the concepts of rationality and motivation, which uses theories and empirical research from psychology/behavioural finance, sociology and critical accounting to systematise, advance and challenge research on impression management. The paper focuses on research that departs from economic concepts of impression management as opportunistic managerial discretionary disclosure behaviour resulting in reporting bias or ‘cheap talk’. Using alternative rationality assumptions, such as bounded rationality, irrationality, substantive rationality and the notion of rationality as a social construct, we conceptualise impression management in alternative ways as (1) self-serving bias, (2) symbolic management and (3) accounting rhetoric. This contributes to an enhanced understanding of impression management in a corporate reporting context. 相似文献

The experience of Canada in the first half of this century indicates that the importance of institutional mortgage lending for the growth of homeownership can be overstated. Home ownership rates in Canada and the United States were similar, but many fewer Canadians than Americans relied on lending institutions. Fewer incurred debt of any sort. A case study of Hamilton, Ontario, based on land titles records indicates that this was especially true during the interwar years. No Canadians lived in large metropolitan areas, where mortgage debt was most prevalent, while many built in stages as their finances allowed. Moreover, even in the early 1950s, half of all residential mortgage debt in Canada was held by private individuals, with brokers playing an important role. Despite the importance of the personal sector, above all in the markets for older homes and junior mortgages, the Canadian government made no effort to improve the way in which it operated. 相似文献
