Regret and rejoicing are two emotions that are defined by comparing the result of an action retained by an agent with respect to the result that he could have obtained from an alternative action. We show that the choice of the alternative action impacts the allocation of risky assets. When it is defined in relation to the ex post maximum expected result, the agent only receives regret. This may lead, for low values of the marginal cost of risk, to retain more risky assets than an agent who maximized a standard expected utility function. On the contrary, the agent could express a preference for certainty and defines his emotions in relation to what a total investment in risk-free assets would bring to him. In this case, we show that investment in risky assets is weaker than the one realized by an agent who maximized a standard expected utility function.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"5 1","pages":"613-639"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80649323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First-best liberal social contracts redistribute individual wealth and determine the level of provision of public commodities to achieve a Pareto-efficient allocation of resources that is unanimously preferred to the allocation of a hypothetical initial situation of perfect communication. We show that the social welfare functionals that aggregate individual social preferences by means of the generalized bargaining solution of Nash support the liberal social contract if they verify non-paternalistic benevolence, that is, if the associate social welfare functions are strictly increasing in the private welfare of all individuals. The existence of a liberal social contract follows as a corollary of this property of supportability. We characterize the liberal social contract as a case of application of Habermas?s norms of communicative action to the allocation of scarce resources by public finance and the market.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"166 1","pages":"267-296"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76180806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

L’analyse est faite a partir d’une approche DEA en deux etapes. Dans la premiere etape, l’efficience des IMF est estimee de facon non parametrique, en executant un modele VRS (de rendements d’echelle variables) a orientation input. Au total six modeles d’efficience sont estimes dont trois concernent l’efficience financiere et trois autres, l’efficience sociale. Les scores d’efficience obtenus dans cette premiere etape sont regresses, dans la seconde etape, sur un ensemble de variables environnementales en suivant la procedure bootstrap truncated de Simar et Wilson [2007], plus robuste que les approches classiques basees sur la regression tobit ou les moindres carrees ordinaires. Les resultats de la premiere etape mettent en evidence une faible efficience des IMF de la zone UEMOA. L’inefficience est a la fois technique et d’echelle, mais s’explique davantage par une mauvaise combinaison technique des ressources. Elle est plus palpable sur le plan social que financier. Les resultats de l’estimation post-dea montrent que la rentabilite economique est un determinant essentiel de l’efficience financiere et sociale. Les IMF les plus rentables economiquement sont les plus efficientes tant au plan social que financier. Les IMF les plus grandes et les plus anciennes sont egalement les moins efficientes au plan social. De meme les IMF a profil non commercial sont les plus efficientes du point de vue social. Toutefois, les resultats montrent que les variables environnementales ont souvent un impact qui varie selon le type de modele specifie.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"76 1","pages":"667-689"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74146362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If rationality can be characterized by conditions on preferences and choices and, in addition, people are, to a reasonable degree of approximation rational, then economists can invoke the theory of rationality to explain choices. If people are also, as in positive economics, largely self-interested and reasonably well-informed, then their preferences will also indicate their level of well-being. Modeling both choice and welfare in terms of rational preferences thus unites positive and normative economics. In explaining market outcomes in terms of individual choices, explaining choices by preferences, and taking preferences to indicate well-being, economists who are concerned with welfare defend a normative theory that piggybacks on their positive theory. This traditional mainstream normative theory is problematic, but because of its unity and its connection to positive economics, it is also very powerful.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"11 1","pages":"191-208"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81465201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a model of household recycling that, while including pecuniary and non pecuniary motives for decisions, such as social or moral norms, reveals heterogeneous values of saving time from recycling (VSTR). The predictions of our model are tested using data from a discrete choice experiment on waste management conducted in 2008 in Corsica and estimating a latent-class rank-ordered logit model. We find VSTR clearly heterogeneous across individuals, ranging from 8 % to 76 % of one’s income. francaisBien qu’il soit clairement etabli que le cout d’opportunite du temps consacre au recyclage constitue un determinant essentiel des decisions des menages en matiere de tri des dechets, tres peu de travaux empiriques ont tente d’en fournir une estimation.

This paper empirically assesses the effect of reforms sequences in the telecommunications sector on the sector performance, by using a sample of?17?Middle East North African (MENA) countries for the period?1995-2010. Countries are free to choose how to proceed notably whether to establish an Independent Regulatory Authority (IRA) before or after privatizing the SOEs, as well as they can create an IRA before introducing competition rather than after. We assume that the choices of reforms sequences are affected by institutional, political and economic variables. We use IV-2SLS estimation to analyze the outcome of reforms sequences in terms of telecom performance (access, prices, productivity and quality). We find that an IRA established before privatizing the incumbent operator improves the sector access but with an increase in fixed prices. However, the effect of an IRA before introducing competition differs between the fixed and the mobile sector. Regulation still works as an imperfect substitute for competition in the fixed market, which is no more the case for the mobile market.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"25 1","pages":"713-743"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89482731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to consider and to distinguish between these two types of research, we merge the seminal models of Romer [1990] and Aghion and Howitt [1992]?: knowledge accumulation stems from a series of inventions (horizontal / fundamental knowledge accumulation) and from a succession of innovations (vertical / applied knowledge accumulation) building upon each of these inventions. Then, we study a decentralized economy in which the creative destruction mechanism does not deter investments in fundamental research through an IP law design that induces profit-division between an inventor and his following innovators. We show that providing optimal incentives to fundamental research requires, not only a design of IP law that ensures a sufficient positive transfer from innovators to inventors, but also public policies in form of subsidies supporting both fundamental research and applied R?&?D activities.","PeriodicalId":44798,"journal":{"name":"REVUE D ECONOMIE POLITIQUE","volume":"142 1","pages":"807-848"},"PeriodicalIF":0.3,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86241060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
