Testing a physical education-delivered autonomy supportive intervention to promote leisure-time physical activity in lower secondary school students:…

2020

© 2020 The Author(s). Background: Inadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students' engagement in leisure-time physical activity. The present study therefore examined the efficacy of an intervention aimed at increasing PE teachers' autonomy support on students' leisure-time physical activity (the PETALS trial). The intervention was guided by the trans-contextual model (TCM) explaining the processes by which PE teachers' provisio…

''Dual'' gravity: Using spatial econometrics to control for multilateral resistance.

2007

We propose a quantity-based `dual' version of the gravity equation that yields an estimating equation with both cross-sectional interdependence and spatially lagged error terms. Such an equation can be concisely estimated using spatial econometric techniques. We illustrate this methodology by applying it to the Canada-U.S. data set used previously, among others, by Anderson and van Wincoop (2003) and Feenstra (2002, 2004). Our key result is to show that controlling directly for spatial interdependence across trade flows, as suggested by theory, significantly reduces border effects because it captures `multilateral resistance'. Using a spatial autoregressive moving average specification, we …

Growth and convergence in Africa: The impact of spatial effects

2010

The aim of this paper is to study the impact of spatial effects on convergence process in Africa over the period 1975-2000. Taking into account these effects through the methodology of Exploratory Spatial Data Analysis (ESDA) and spatial econometrics, we focus on the geographical dimension of economic convergence of African countries. This allows us to deal with spatial autocorrelation which is a consequence of econometric interdependences due to geographic spillovers. Indeed, countries economic performance hides specific geographical patterns providing information on the importance of location on economic dynamics. Our results prove the existence of convergence process in Africa through a …

Cooperación condicional y tercer sector

2000

The following paper analyzes the problem of social cooperation in the provision of a public good from an evolutionary perspective. To this end we depart from behavioral programs as the basic building block for modeling individuals in the social interaction, which is based on a generalized prisoners dilemma. In it, a population of individuals follow a conditional cooperative program, which some authors refer as to morality, and that we will show that is equivalent to the application of the principle of reciprocity. It will be shown that the degree of cooperation, that is the individual contribution toward the provision of the public good, is positive although sub-optimal. Finally, if we comp…

Exchange Rate Arrangements in Central and Eastern European Countries – Evolutions and Characteristics

2007

The process of choosing the exchange rate regime for the new EU member states has been influenced by other criteria than the traditional ones, which belong to macroeconomic criteria. This paper make a comparative analyze of the exchange rate arrangements in Central and Eastern European after 1990. These arrangements are dynamic on the one hand due to their permanent diversification and on the other hand because the values established this way are rapidly changing. In essence, they differ according to the degree of flexibility adopted when the exchange rate is established: from more rigid forms – currency board or pegging the currency to a foreign currency – to free floating.

Variation sur le thème 'A la recherche de nouvelles fondations pour la finance et la gouvernance d'entreprise'

2001

L'objectif de cet article est de proposer une voie alternative à celle que préconise Zingales pour donner de nouvelles fondations à la finance d'entreprise. En empruntant le même cheminement que Zingales, cet article retient premièrement une définition plus large de la finance, accordant à l'investissement une place au moins équivalente à celle du financement. Deuxièmement, considérant que la vision contractuelle, dans son interprétation traditionnelle fondée sur la protection des actifs spécifiques, conduit à une théorie financière déconnectée de toute considération productive, il propose de lui substituer les théories de la firme associées aux courants cognitifs. Troisièmement, les conséq…

Privatisation, gouvernement d'entreprise et processus décisionnel:une interprétation de la dynamique organisationnelle à travers le cas France Télécom

2001

This article tries to explain the influence of privatization on the decision making process, especially in terms of investments through the corporate governance theory. In this perspective we suggest a conceptual framework based on the analysis of disciplinary mechanisms and their dynamic as a foundation of an explanatory research applied to the France Télécom case.

The workers' value of the remaining employment contract duration

2005

We introduce and apply a method for estimating workers' marginal willingness to pay for job attributes employing data on job search activity. Worker's willingness to pay for the remaining duration of the employment contract is derived. We provide evidence that workers attach substantial value to the remaining contract duration. A temporary worker with a remaining contract of six months is willing to pay about 10% of the monthly wage to increase the contract by one month.This discussion paper has resulted in a publication in Economica, 2008, 75(297), 116-39.

Mobility, wages and gender across Europe

2012

In this paper, the socioeconomic and individual characteristics that favor mobility are analyzed. The stochastic frontier technique is used as an instrument of analysis to measure the differences that arise between the potential wage and the one that should be obtained for an individual with particular socioeconomic characteristics given his/her investment in human capital. A data panel of young workers who have been working at least for seven consecutive years is used for this analysis. The data set comes from the European Community Household Panel for the period 1995-2001. The results show that Spanish and Italian women have the higher changing probability; this high probability has a neg…
