The physiocrats' concept of labour: A difficulty in Marx's interpretation

Abstract

This article explains the difference between the concept of labour developed by the Physiocrats and Marx. We show that Marx's interpretation based on Turgot is questionable. Whereas Marx bases his ideas on a Lockian definition of labour which puts labour at the origin of value, Quesnay and his disciples develop a mechanistic definition of labour established on Neo-Cartesian foundations. This particular concept of labour then combines with a bio-physical definition of production. The theory of the net product is therefore re-interpreted.     

Limits to agri-environmental schemes uptake to mitigate human–wildlife conflict: lessons learned from Flamingos in the Camargue,southern France

Agri-environment schemes (AES) favouring the maintenance of hedges were implemented in the Camargue (southern France) as it has previously been proven to reduce the risk of damage caused by Greater Flamingo incursions into rice fields. Given the persistent incursions, we estimated the economic cost of damage from 2007 to 2009, the uptake rate of hedge-related AES and explored the limits of these schemes as a mitigation effort. Semi-structured and key informant interviews, site mapping and field visits were made to verify claims and estimate damage. Number of plants/m² and fertile stems/plant were estimated on 1,498 and 312 grids, respectively, spread over 26 rice fields. Damaged areas of rice fields forayed by flamingos presented from 1.35 to 3.06 t/ha lower yield than undamaged areas. We estimated 228€/ha average loss in forayed fields for a total of 400,000€ in yield loss in 2008. Administrative constraints limited AES and free seedlings distribution, preventing the problem from being addressed at an appropriate scale. The trivial financial support for hedge management relative to more lucrative AES with lower constraints resulted in low uptake rate. We propose that modifications of AES take into account landscape factors over administrative boundaries and that the financial support for AES be scaled up relative to other subsidies in order to address the efforts necessary to achieve landscape changes to reduce human–wildlife conflict.     

Sport as a cultural system: sports policies and (new) ethnicities in Lyon and Birmingham

‘Sport promotes integration’: this idea seems to be commonly accepted both in France and in the UK, even though the authorities in each country see the issue of ‘ethnic minorities’ very differently. This article draws on research based on interviews with the main actors of ‘socio–sports’ policies in the cities of Lyon and Birmingham and on analysis of consultation procedures and official documents, to show that sport provides a set of symbolic markers that helps the authorities, professionals and ‘ethnic minorities’ to get their bearings in an uncertain multicultural situation. Although ‘ethnic minorities’ try to control the direction of sports policies in pursuit of their own objectives, their strategies tend to be ‘routinized’ around markers legitimized by the authorities in response to the success of certain sporting practices. Sports policies, therefore, promote ‘security’ of identity for these ‘minorities’ by ‘mapping’ their environment using the values and principles of sport. ‘Le sport favorise l’int´gration’: cette idée semble communément admise en France et en Grande–Bretagne alors même que leurs autorités respectives envisagent de manière très différente la question des ‘minorités ethniques’. À partir d’une recherche fondée sur des entretiens avec les principaux acteurs des politiques ‘socio–sportives‘ des villes de Lyon et de Birmingham, et sur l’analyse des procédures de concertation et des documents officiels, l’analyse montre que le sport trace des repères symboliques qui permettent aux pouvoirs publics, aux professionnels et aux ‘minorités ethniques’ de s’orienter dans une réalité multiculturelle incertaine. Mais si ces dernières tentent de contrôler l’orientation des politiques sportives de manière à poursuivre leurs propres objectifs, leurs stratégies tendent également à se ‘routiniser’ autour des repères que les pouvoirs publics ont légitimé pour répondre au succès des pratiques sportives. Les politiques sportives favorisent dès lors la ‘sécurisation’ identitaire de ces ‘minorités’ en ‘cartographiant’ leur environnement à l’aide des valeurs et des principes du sport.     

French unemployment: a transatlantic perspective

The paper compares the French and US labour markets. It shows that differences in unemployment rates are especially acute for young and old workers, but appear to be negligible for middle-aged workers. All French workers, however, experience job flows that are quite distinct from their American counterparts as they are exposed to long spells of infrequent unemployment, which is the opposite to the US case. Critical differences across ages and skills regarding the patterns of exit from and entry into employment are also displayed. The paper dispels the view that these differences originate from the behaviour of the unemployed (or the set of institutions that guide their decisions), and that this is new to the French labour market.     

Inference on an extended Roy model,with an application to schooling decisions in France

This paper considers the identification and estimation of an extension of Roy’s model (1951) of sectoral choice, which includes a non-pecuniary component in the selection equation and allows for uncertainty on potential earnings. We focus on the identification of the non-pecuniary component, which is key to disentangling the relative importance of monetary incentives versus preferences in the context of sorting across sectors. By making the most of the structure of the selection equation, we show that this component is point identified from the knowledge of the covariate effects on earnings, as soon as one covariate is continuous. Notably, and in contrast to most results on the identification of Roy models, this implies that identification can be achieved without any exclusion restriction nor large support condition on the covariates. As a by-product, bounds are obtained on the distribution of the ex ante   monetary returns. We propose a three-stage semiparametric estimation procedure for this model, which yields root-n$n$ consistent and asymptotically normal estimators. Finally, we apply our results to the educational context, by providing new evidence from French data that non-pecuniary factors are a key determinant of higher education attendance decisions.     

Surplus measures and luenberger Hicks–Moorsteen productivity indicator

This paper extends to production theory some notions of compensated and equivalent variation analyzed in Luenberger (Econ Theory 7:445–462, 1996) in a consumer context. Along this line the Luenberger–Hicks–Moorsteen productivity indicator introduced in Briec and Kerstens (Econ Theory 23:925–939, 2004) is derived from these concepts for multi-output production technologies. The dual properties of this productivity indicator are analyzed and an aggregate indicator is introduced inspired from the resource function proposed in Luenberger (1996). A connection to a suitable Slutsky matrix is established.     

Liberal Jansenists and interest-bearing loans in eighteenth-century France: a reappraisal

Abstract

This article is an attempt to prove that although the liberal Jansenists – Jansenism being the most powerful Christian protest movement of the seventeenth and eighteenth centuries – were not the first and the only ones to address the prohibition of interest-bearing loans, their writings on the issue shifted and fuelled the debate during the French Enlightenment, especially among the Encyclopédistes and the economists. By refuting the very logic of “extrinsic titles” of the Scholastics and their extension later on by the Jesuits, the liberals Jansenists redefined “interest” as the price to be paid for the use of money.     

Modeling voter choice to predict the final outcome of two-stage elections

Most election forecasting research to date has been conducted in the context of single-round elections. However, more than 40 countries in the world employ a two-stage process, where actual voting data are available between the first and the second rounds to help politicians understand their position in relation to each other and to voter preferences and to help them predict the final outcome of the election. In this study we take advantage of the theoretical foundation on voter behavior from the political science literature and the recent methodological advances in choice modeling to develop a Nested Logit Factor Model of voter choice which we use to predict the final outcome of two stage elections and gain insights about the underlying political landscape. We apply the proposed model to data from the first stage and predict the final outcome of two stage elections based on the inferences made from the first stage results. We demonstrate how our proposed model can help politicians understand their competitive position immediately after the first round of actual voting and test its predictive accuracy in the run-off election across 11 different state governorship elections.     

A multi-stage model of word-of-mouth influence through viral marketing

With the growth and evolution of the Internet, electronic peer-to-peer referrals have become an important phenomenon, and marketers have tried to exploit their potential through viral marketing campaigns. At the same time, spam and e-mail-based viruses have cluttered electronic communications, making viral marketing campaigns problematic and challenging to deploy. The key driver in viral marketing is the effectiveness of unsolicited, electronic referrals to create awareness, trigger interest, and generate sales or product adoption. Yet, despite a large literature concerning interpersonal influence, little is known about how this electronic, or, indeed, any word-of-mouth process influences consumers' actual behaviors, particularly in a cluttered online environment. In this paper, we develop a model to help identify the role word-of-mouth plays during each stage of a viral marketing recipients' decision-making process, including the conditions that moderate such influence. We then present an innovative methodology for collecting data unobtrusively and in real time. We empirically test the model and methodology via a field study, where we observed the reactions of 1100 individuals after they received an unsolicited e-mail from one of their acquaintances, inviting them to take a survey and in turn spread the word about it. We found that characteristics of the social tie influenced recipients' behaviors, but had different effects at different stages: tie strength facilitated awareness, perceptual affinity triggered recipients' interest, and demographic similarity had a negative influence on each stage of the decision-making process. We conclude with a discussion of the theoretical and methodological contributions of our work and of managerial implications of these findings for online marketers interested in strategies for leveraging peer-to-peer referral networks.
