Desafios da política monetária em Marrocos: Explorar a possibilidade de conciliar a estabilidade dos preços e o crescimento económico
Get PDFIn this research paper, we used the VECM framework to assess Moroccan central bank’s ability to target inflation. We also explored the possibility of reconciling between inflation control and growth stimulation through an impulse response analysis. Our empirical results showed that interest rate adjustments as monetary policy measure could be a relevant choice in a context of moderate and short-lived inflation since it provides a wide margin for reconciling price stability and economic growth. In times of high and persistent inflation, the central bank should prioritize inflation control through a permanent decrease in its money supply.Neste artigo de investigação, utilizámos o quadro VECM para avaliar a capacidade do banco central marroquino de atingir a inflação. Também explorámos a possibilidade de conciliação entre o controlo da inflação e a estimulação do crescimento através de uma análise de resposta ao impulso. Os nossos resultados empíricos mostraram que os ajustamentos das taxas de juro como medida de política monetária podem ser uma escolha relevante num contexto de inflação moderada e de curta duração, uma vez que proporcionam uma ampla margem para conciliar a estabilidade de preços e o crescimento económico. Em tempos de inflação elevada e persistente, o banco central deve dar prioridade ao controlo da inflação através de uma diminuição permanente da sua oferta monetária
Os determinantes do desempenho escolar em países seleccionados do Médio Oriente e do Norte de África: qual o papel das características do sistema educativo?
Get PDFBased on data from the 2011 TIMSS international survey related to the 2nd year of secondary school of eleven MENA countries, this work aims to identify the characteristics of the educational system that influence the students' academic performance in mathematics in these countries, while highlighting the case of Morocco.The estimation of an empty three-level model, to explain the probability of achieving a score of 400 points or more in mathematics, showed that a significant and non-negligible part (8.04%) of the total variance is due to the differences between the characteristics of the countries.The results of this study showed that, particularly in Morocco, students' academic performance could be improved by providing autonomy to schools to choose the syllabus, by making preschool a obligatory educational cycle and by increasing the volume of time reserved for teaching mathematics.Basé sur les données de l’enquête internationale TIMSS 2011 relatives à la 2ème année de l’enseignement secondaire collégial concernant onze pays de la zone du MENA, ce travail a pour objectif l’identification des caractéristiques du système éducatif qui influent sur la performance scolaire en mathématique des élèves des pays de cet échantillon, tout en mettant en lumière le cas du Maroc.
L’estimation d’un modèle vide à trois niveaux, pour l’explication de la probabilité que les élèves réalisent un score supérieur ou égal à 400 points en mathématiques, a permis de constater qu’une part significative et non négligeable (8,04%) de la variance totale est due aux différences entre les caractéristiques des pays.
Les résultats de cette étude ont montré, que particulièrement au Maroc, le rendement scolaire des élèves pourrait être amélioré en accordant une autonomie aux établissements dans le choix des programmes scolaires, en faisant du préscolaire un cycle d’enseignement obligatoire et en augmentant le volume horaire réservé à l’enseignement des mathématiques.Com base nos dados do inquérito internacional TIMSS 2011 sobre o 2.º ano do ensino secundário para onze países do MENA (Médio Oriente e do Norte de África), este estudo tem como objetivo identificar as características do sistema educativo que influenciam o desempenho matemático dos alunos nos países da amostra, destacando o caso de Marrocos. A estimação de um modelo de vácuo de três níveis para explicar a probabilidade de os alunos alcançarem uma pontuação de 400 pontos ou mais em matemática revelou que uma proporção significativa e não negligenciável (8,04%) da variância total se deve a diferenças entre as características dos países.Os resultados deste estudo mostraram que, nomeadamente em Marrocos, o desempenho académico dos alunos poderia ser melhorado concedendo autonomia às escolas na escolha dos programas, tornando o ensino pré-escolar obrigatório e aumentando o tempo consagrado ao ensino da matemática
Um estudo sobre a eficácia do desenvolvimento financeiro no crescimento económico de Marrocos
Get PDFEconomic growth’s theories suggest that a developed financial sector can promote the economy growth. However, the ability of financial sector to boost the economic growth depends on its ability to finance the economy.This paper investigates the relationship between Morocco's economic growth and financial development (FD). We base our study on the crucial role of banking sector in economic growth in developing countries through their financial intermediation. In order, to verify this relationship the vector error correction model (VECM) is used on secondary data: real GDP per capita (GDP) and a set of explanatory variables representing the financial development sector, specifically the ratio of private sector credit (CPS) and control variables including the share of government consumption (PC), the real interest rate (IR), trade openness (TO), and the inflation rate (INF). Our secondary data comes from the Central Bank of Morocco database and covers 56 quarters from 2007Q1 to 2020Q4. The findings support the long- and short-term benefits of financial sector development for economic growth in Morocco. As teorias do crescimento económico sugerem que um sector financeiro desenvolvido pode promover o crescimento da economia. No entanto, a capacidade do sector financeiro para impulsionar o crescimento económico depende da sua capacidade de financiar a economia.Este documento investiga a relação entre o crescimento económico de Marrocos e o desenvolvimento financeiro (DF). Baseamos o nosso estudo no papel crucial do sector bancário no crescimento económico dos países em desenvolvimento através da sua intermediação financeira. Para verificar esta relação, é utilizado o modelo vetorial de correção de erros (VECM) com base em dados secundários: PIB real per capita (PIB) e um conjunto de variáveis explicativas que representam o sector do desenvolvimento financeiro, especificamente o rácio do crédito ao sector privado (CPS) e variáveis de controlo, incluindo a percentagem do consumo público (PC), a taxa de juro real (IR), a abertura comercial (TO) e a taxa de inflação (INF). Os nossos dados secundários provêm da base de dados do Banco Central de Marrocos e abrangem 56 trimestres de 2007T1 a 2020T4. Os resultados confirmam os benefícios a longo e a curto prazo do desenvolvimento do sector financeiro para o crescimento económico em Marrocos. Palavras-chave: crescimento económico, desenvolvimento financeiro, crédito privado à economia, modelo vetorial de correção de erros (VECM), Marrocos
