Unconditional quantile regression analysis of UK inbound tourist expenditures

Sharma, Abhijit, Woodward, R., Grillini, Stefano 09 December 2019 (has links)
Yes / Using International Passenger Survey (2017) data, this paper employs unconditional quantile regression (UQR) to analyse the determinants of tourist expenditure amongst inbound tourists to the United Kingdom. UQR allows us to estimate heterogeneous effects at any quantile of the distribution of the dependent variable. It overcomes the econometric limitations of ordinary least squares and quantile regression based estimates typically used to investigate tourism expenditures. However, our results reveal that the effects of our explanatory variables change across the distribution of tourist expenditure. This has important implications for those tasked with devising policies to enhance the UK’s tourist flows and expenditures.

Uma análise da relação entre violência na escola e proficiência dos alunos

Dalcin, Aline Krüger January 2016 (has links)
O Brasil é um dos países mais violentos do mundo, e essa realidade se reflete no ambiente escolar. O problema da violência na escola induz nos agentes de educação comportamentos que se contrapõem às metas de melhoria da qualidade do ensino. Por isso, a violência na escola é um dos candidatos a determinante da baixa qualidade educacional encontrada no Brasil. Este trabalho investiga se existe relação entre violência na escola e proficiência dos alunos no Brasil nos anos de 2003, 2005, 2007, 2009, 2011 e 2013. Os resultados das regressões lineares e das regressões quantílicas incondicionais indicam que a ocorrência de um tipo de evento violento adicional está associada a uma redução na proficiência. Eles indicam também que há heterogeneidade na resposta dos alunos à violência na escola: a violência na escola parece afetar mais os alunos da quarta série, os alunos que se encontram na mediana da distribuição das notas e os alunos com melhor condição socioeconômica. Além disso, a violência na escola parece afetar mais a proficiência em Matemática em comparação com a proficiência em Língua Portuguesa, e a violência contra o professor tem efeitos tão ou mais deletérios que a violência entre os alunos. / Brazil is one of the most violent countries in the world, and this reality is part of the school environment. The problem of school violence hinders any possible progress in improving the quality of education. Indeed, school violence is a key element in explaining the low educational quality in Brazil. This research investigates the relationship between school violence and student achievement in Brazil in the years of 2003, 2005, 2007, 2009, 2011 and 2013. The results of linear regressions and unconditional quantile regressions analysis show that an occurrence of an additional kind of violent event is associated with a reduction on student achievement. They also show that there is a high degree of heterogeneity in student responses to school violence: the school violence seems to affect more 4th graders, the students that are in the median of the distribution of the grades and the students with the best socioeconomic conditions. Moreover, school violence seems to affect more grades in Math than Portuguese, and the violence against teachers has effects as or more deleterious than the violence between students.

Quatre essais sur les inégalités et l'instabilité macroéconomique / Four essays on inequality and macroeconomic instability

Gueuder, Maxime 22 December 2017 (has links)
Cette thèse porte sur l’étude des inégalités dans un cadre macroéconomique, d’un point de vue théorique ainsi qu’empirique. Dans un premier chapitre, j’écris et simule un modèle basé-agents capable de répliquer les distributions fat-tailed des richesses observées empiriquement dans les économies développées. Dans un second chapitre, je prolonge ce modèle théorique pour étudier l’impact économique des discriminations interpersonnelles et institutionnelles. Lorsque les discriminations institutionnelles cessent, l’état final des inégalités dépend de l’économie au moment de la fin de ces discriminations : plus l’économie est organisée, plus le temps nécessaire à une égalisation des revenus et richesses entre ethnies est long, voire infini. Dans un troisième chapitre empirique, j’étudie l’évolution des inégalités de salaire entre Noirs et Blancs aux États-Unis entre 1960 et 2015, en me concentrant sur la période 2000-2015. Je traite les biais de sélection liés à l’asymétrie raciale envers l’emprisonnement, et montre que l’écart - en conditionnant par l'âge et les diplômes - entre salaires médians des Noirs et des Blancs atteint un maximum en 2012. En utilisant la méthode de régression quantiles non-conditionnelles conjointement avec la décomposition de Blinder-Oaxaca, j’établis que la part non-expliquée de cet écart reste stable durant la Grande Récession. Enfin, dans une post-face, en utilisant les métadonnées de RePEC, j’établis que la part des articles scientifiques consacrés à l’étude des crises augmente significativement après 2008 pour 13 des 30 « top journals » en économie. / This PhD dissertation focuses on wealth and wage inequality, and the macro-economy. In a first chapter, I write and run a small macro agent-based model (M-ABM) in which I study the resultant distribution of wealth among households. I show that this model generates fat- tailed distributions of wealth in the household sector, as empirically observed in advanced economies. In a second chapter, I extend this model to study the macroeconomics of interpersonal and institutional discriminations against racial minorities. When discrimination is at work, racial disparities in income and wealth arise. The effect of the abolition of institutional discrimination is path-dependant: the more the economy is organized when this institutional change occurs, the more time it takes to get back to the counter-factual situation where no institutional discrimination was set up in the first place. In a third chapter, I study the evolution of the difference of median log-annual earnings between Blacks and Whites in the US between 1960 and 2015, focusing on the 2008 crisis. I control for selection arising from racial differentials in institutionalised population, and find that the unconditional racial wage gap attains a maximum in 2012. Controlling for age and education, I obtain the same result. Using unconditional quantile regressions, I show that the unexplained part of the unconditional racial wage gap has not increased during the crisis. Finally, in an afterword, I use metadata from RePEC to show that the share of economics papers published in the 13 of the 30 "top" journals containing "crisis" in their titles and/or abstracts has significantly increased in 2008.
