    (the Asymmetric Impact Of Economic Growth On Unemployment In Algeria- Testing The Okun's Law (empirical Study For The Period 1980-2018
    (جامعة الوادي - University of Eloued, 2020-09-15) Manna, Lamdjed; Rimi, Riadh; Touitou, Mohammed
    The objective of this paper is to test the asymmetric effect between the change in unemployment rates (as a dependent variable) and the real economic growth (as an independent variable) according to the okun's law of the Algerian economy in 1980-2018 basing nonlinear Autoregressive Distributed Lag (NARDL). empirical results confirmed the absence of the equilibrium relationship - the long-term relationship - which interprets the absence of okun's law The asymmetry test also shows symmetry in the long-term relationship, but empirical results shows that there is asymmetry in the short-term relationship. تهدف هذه الورقة البحثية إلى اختبار الأثر اللامتماثل بين التغير في معدلات البطالة والنمو الاقتصادي حسب قانون أوكون (okun) للاقتصاد الجزائري ضمن الفترة 1980-2018 بالاعتماد على منهجية الانحدار الذاتي ذو الابطاءات الموزعة زمنيا اللاخطي(NARDL)، بحيث أكدت النتائج التجريبية غياب العلاقة التوازنية – العلاقة طويلة الأجل- مما يترجم غياب قانون أوكون في المدى الطويل، كما أن اختبار عدم التماثل يوضح وجود تماثل(symmetric) في العلاقة طويلة الأجل لكن العلاقة قصيرة الأجل تظهر النتائج التجريبية عدم وجود تماثل (Asymmetric).

    An empirical evaluation of the pricing system of automobile insurance in Algeria
    (جامعة الوادي University of Eloued, 2015-12-31) Rimi, Riadh; Latreche, Abdelouhab; Rimi, Okba
    Le principal problème de l’assurance automobile en Algérie est le faible niveau des primes, déterminées par le ministère des Finances. Nous avons proposé, dans cette étude, de formaliser un modèle de tarification basé sur les caractéristiques des assurés (tarification a priori) et sur le nombre d’accidents passés des individus (tarification a posteriori) à l'aide d'un système Bonus-Malus. La méthodologie utilisée pour calibrer un système Bonus-Malus à la française, est celle proposée par (PITREBOIS, et al., 2003c). La comparaison entre le système de tarification appliqué par le ministère des Finances et le système théorique obtenu dans notre étude nous a permis de conclure que le système de tarification appliqué par le ministère des Finances n'est pas optimal. Abstract: The main problem of auto insurance in Algeria is the low level of the premiums, determined by the Ministry of Finance. We have proposed in this study, to formalize a pricing model based on the characteristics of the insured (pricing a priori) and the number of accidents went individuals (post pricing) using a system Bonus-Malus. The methodology used to calibrate a Bonus-Malus system in French, is that proposed by (PITREBOIS, et al., 2003c). The comparison between the tarification system applied by the Ministry of Finance and the theoretical system obtained in this study allowed us to conclude that the tarification system applied by the Ministry of Finance is not optimal
