Does acclamation equal agreement? Rethinking collective effervescence through the case of the presidential “tour de France” during the twentieth century

This article discusses the integrative function frequently assigned to festive events by scholars. This function can be summed up in a proposition: experiencing similar emotions during collective gatherings is a powerful element of socialization. The article rejects this oft-developed idea according to which popular fervor could be an efficient tool to measure civic engagement. It raises the following question: what makes enthusiasm “civic”, “patriotic”, “republican” or simply “political”? Based on a study of French presidential tours in France from 1888 to 2007, this article casts a different light on the topic. The enthusiasm of the crowds interacting with the successive French presidents is not civic because an inquiry may find “patriotism” into participants’ minds. It can be called civic simply because the forms and meaning of the festive jubilation, which may be summarized into the formula: “if spectators applaud, it means they support,” necessarily preexist its multiple manifestations.     

Utilitarianism or welfarism: does it make a difference?

We show that it is possible to reconcile the utilitarian and welfarist principles under the requirement of unanimity provided that the set of profiles over which the consensus is attained is rich enough. More precisely, we identify a closedness condition which, if satisfied by a class of n-tuples of utility functions, guarantees that the rankings of social states induced by utilitarian and welfarist unanimities over that class are identical. We illustrate the importance of the result for the measurement of unidimensional as well as multidimensional inequalities from a dominance point of view.     

The Impact of Tax-Benefit Reforms on Labor Supply in a Simulated Nash-bargaining Framework

Several theoretical contributions have suggested to model household behavior as a Nash-bargaining game. Yet very few attempts have been made to operationalize cooperative models of labor supply for policy analysis. In this paper, we implement a Nash-bargaining model with external threat points (divorce) into the microsimulation of tax-benefit policy reforms in France. The observation of divorced individuals is used to predict outside options and (some) of the preferences for individuals living in couples. Benchmark simulations are conducted in a way that guarantees consistency with the Nash bargaining setting, regularity conditions and observed behavior. We examine how the labor supply of couples adjusts to shocks on threat points, either hypothetical or generated by a radical tax-benefit reform.     

Men’s Judgment and Behavior Toward Women Wearing High Heels

Research has consistently shown that the appearance of women’s apparel influences men’s behavior and judgment. However, the effect of women’s shoe heels has received little interest. Female confederates wearing black shoes with 0-, 5-, or 9-cm heels walked on the street. In a first experiment, we examined the number of men in the street who smiled at the female confederate. More smiles were addressed to the confederate with high heels. In a second experiment, the confederates asked men and women to respond to a short survey. It was found that high heels increased males’ but not females’ compliance with the request. In a third experiment, photographs of the same woman’s body profile wearing high heels or not were evaluated by men. Results showed that high heels were associated with greater sexiness, overall physical attractiveness, breast attractiveness, beauty, attractiveness to other men, and willingness to date. All the experiments supported the notion that high heels increase women’s attractiveness to men.     

Nested Kriging predictions for datasets with a large number of observations

This work falls within the context of predicting the value of a real function at some input locations given a limited number of observations of this function. The Kriging interpolation technique (or Gaussian process regression) is often considered to tackle such a problem, but the method suffers from its computational burden when the number of observation points is large. We introduce in this article nested Kriging predictors which are constructed by aggregating sub-models based on subsets of observation points. This approach is proven to have better theoretical properties than other aggregation methods that can be found in the literature. Contrarily to some other methods it can be shown that the proposed aggregation method is consistent. Finally, the practical interest of the proposed method is illustrated on simulated datasets and on an industrial test case with \(10^4\) observations in a 6-dimensional space.     

Fear of Ruin

This paper offers interpretations and applications of the “fear of ruin” coefficient (Aumann and Kurz, 1977, Econometrica). This coefficient is useful for analyzing the behavior of expected utility maximizers when they face binary lotteries with the same worse outcome. Comparative statics results of “more fear of ruin” are derived. The partial ordering induced by the fear of ruin coefficient is shown to be weaker than that induced by the Arrow-Pratt coefficient.

Wheelchair coasting downhill is a reliable work task

OBJECTIVE: To measure test-retest reliability of physiological responses during submaximal wheelchair downhill and horizontal treadmill ergometry. DESIGN: A test-retest design was used on a convenience sample. Four male and three female non-wheelchair users, (22-43 years of age) propelled or coasted in a wheelchair under steady-state conditions. Four minute work bouts were performed at 1, 2, 3, and 4 km/hr. (0.62, 1.24, 1.86 and 2.5 mph, respectively) at 0 degrees, -2 degrees, and -4 degrees. Subjects were studied twice under each of the 12 conditions. Six tests were performed daily, with testing occurring over four days. Dependent variables included oxygen consumption, minute ventilation and heart. Intraclass correlation coefficients were determined for each set of paired tests. RESULTS: Intraclass correlation coefficients were high for absolute VO_{2}(R=0.84-0.99), V_{E} (R=0.86-0.98) and HR (R=0.95-1.0) over the range of 4 speeds and 3 inclinations studied. On average, % differences from test 1 to test 2 were less than 3%. CONCLUSION: At the treadmill speeds and inclinations (positive and negative) studied in this investigation, untrained wheelchair users responded in a physiologically reliable manner.     

Nontariff Barriers and Trade Liberalization

This article shows that governments have no incentive to introduce nontariff barriers (NTBs) when they are free to set tariffs but they do when tariffs are determined cooperatively. Quotas are preferred to antidumping restrictions so that the model is consistent with a progression from using tariffs only to quotas and then to antidumping constraints (when quotas are eliminated). There is a corresponding narrowing of the range of industries affected by trade restrictions. Simulating the model, the degree of tariff liberalization and of replacement of tariffs by NTBs are shown to depend on industry characteristics in line with stylized facts.
