Construction de logements sociaux et stratégies électorales locales,
2013
Our article examines if local incumbents’ choices regarding social housing construction are influenced by strategic electoral considerations, which might foil the French state’s efforts in favour of greater social mixity. By constructing a probabilistic voting model which integrates a partially mobile population, we show that such strategic considerations let the political choices of neighbouring municipalities become interdependent, and that the intensity of the resulting strategic inter-actions varies in function of the local population’s mobility. These propositions are confirmed by our empirical analysis concerning social housing construction in the Greater Lyon region. A local incumben…
Factor Structure and Longitudinal Factorial Validity of the Core Self-Evaluation Scale
2018
Abstract. The personality high-order concept of core self-evaluations (CSE), which refers to a basic evaluation of one’s worth, capability, and effectiveness, has attracted a lot of research interest. Yet little is known about the construct validity of the core self-evaluation scale (CSES) while information on its longitudinal factorial validity is wholly lacking. This study investigated the factor structure of the CSES using both confirmatory and exploratory factor analysis implemented in Mplus program. In addition, the factor loading invariance over time was investigated using exploratory structural equation modeling. Longitudinal data with three follow-ups over 2 years, gathered among u…
About some difficulties with the functional forms of Lorenz curves
2022
We study to what extent some functional form assumption on the Lorenz curve are amenable to calculating headcount poverty, or poverty threshold, the key concept to determine a poverty index. The difficulties in calculating it have been underestimated. We must choose some functional forms for the Lorenz concentration curve. We examine three families of one-parameter functional forms to estimate Lorenz curves: power (elementary and Pareto), exponential (elementary and Gupta) and fractional (Rohde). Computing these numerical functions may be difficult and impose some restrictions on their domain of definition, may impose to use some numerical approximation methods. The elementary power and exp…
The Love of Money, Satisfaction, and the Protestant Work Ethic: Money Profiles Among Univesity Professors in the U.S.A. and Spain
2004
This study tests the hypothesis that university professors (lecturers) (in the U.S. and Spain) with different money profiles (based on Factors Success, Budget, Motivator, Equity, and Evil of the Love of Money Scale) will differ in work-related attitudes and satisfaction. Results suggested that Achieving Money Worshipers (with high scores on Factors Success, Motivator, Equity, and Budget) had high income, Work Ethic, and high satisfaction with pay level, pay administration, and internal equity comparison but low satisfaction with external equity comparison. Careless Money Admirers (high Success but low Budget) had low intrinsic job satisfaction and low satisfaction with pay level and life. A…
Robust H∞ synchronization of a hyper-chaotic system with disturbance input
2013
Abstract This paper concerns the robust control problems on the synchronization of a hyper-chaotic system with disturbance input. Using an appropriate Lyapunov function, we design the multi-dimensional and the single-dimensional robust H ∞ synchronization controllers in terms of linear matrix inequalities for the application in practical engineering. Corresponding theoretical derivations are given subsequently. Finally, some numerical simulations are provided to demonstrate the effectiveness of the proposed techniques.
A generalized Degn–Harrison reaction–diffusion system: Asymptotic stability and non-existence results
2021
Abstract In this paper we study the Degn–Harrison system with a generalized reaction term. Once proved the global existence and boundedness of a unique solution, we address the asymptotic behavior of the system. The conditions for the global asymptotic stability of the steady state solution are derived using the appropriate techniques based on the eigen-analysis, the Poincare–Bendixson theorem and the direct Lyapunov method. Numerical simulations are also shown to corroborate the asymptotic stability predictions. Moreover, we determine the constraints on the size of the reactor and the diffusion coefficient such that the system does not admit non-constant positive steady state solutions.
Switching to floating exchange rates, devaluations, and stock returns in MENA countries
2012
Abstract We test for the impact of the announcements of floating and/or devaluating the exchange rate on stock returns in three MENA countries after the financial crises they experienced. We, first, use an event-study methodology to test for event-induced abnormal volatility of stock returns in Egypt, Morocco and Turkey. We, then, use three different methodologies to test for abnormal returns: a traditional approach and two approaches that control for event-induced volatility. We find clear evidence of abnormal volatility and abnormal returns due to the floating of the Egyptian and Turkish exchange rates in 2003 and 2001, respectively. In contrast, our results do not show that the devaluati…
The Politics of Explanatory Nationalism and the Evolution of the United Nations Agenda on Multinational Enterprises
2020
The contemporary world continues to suffer from a number of social problems that are global in scope but impact the Global South disproportionately. While broad and coordinated policy responses to overcome these problems exist, such policies are not shaped solely by the political will to address the problems. On the contrary, their content largely depends on how societies in general and the social problems in particular are routinely explained and conceptualized. We refer to these as explanatory tendencies or paradigms of explanation. As complex problems always have multiple root causes with long causal chains, explanations of these causes necessarily involve some assumptions about relevant…
The effect of peer socioeconomic status on student achievement: a meta-analysis
2010
Previous studies on the effects on students’ test scores of their peers’ socioeconomic status (SES) have reported varying results. In order to understand why researchers have alternately found small effects, large effects, or no effects at all, a meta-regression analysis including an extensive database of 30 studies on the topic was conducted. Results show that the size of the compositional effect that researchers find is strongly related to how they measure SES and to their choice of model. Measuring SES dichotomously (e.g. free lunch eligibility) or including several average SES variables in one model leads to smaller effect estimates than using a thoroughly constructed composite that inc…
The shadow economy in Portugal: An analysis with the MIMIC approach
2007
The paper estimates the Portuguese Shadow Economy (SE) from 1977 to 2004 and tests the statistical relationships between the SE and other economic variables. In order to carry out the econometric analysis, a multiple indicators multiple causes (MIMIC) model with means and intercepts is applied. The main causes of the Portuguese SE are analyzed and economic policies to reduce it are suggested. An appraisal on the reliability of estimates and an alternative benchmark strategy for the MIMIC approach are proposed.
