Item FONDEMENTS THEORIQUES ET MATHEMATIQUES DE LA RIGIDITE DES PRIX ET DES SALAIRES ET SON ROLE DANS L’EXPLICATION DE L’EQUATION D’OA = THEORETICALS AND MATHEMATICALS BASISES OF PRICES AND WAGES RIGIDITY AND ITS ROLE ON EXPLANATION OF SRAS* EQUATION(Université M'Hamed Bougara Boumerdes, 2016) Abouderaz, SofianeDepuis près de quatre-vingt ans le débat était lancé entre Keynésiens et classiques sur le fonctionnement des marchés et le comportement de leurs composantes, tel que les agents économiques, ce débat a enrichi remarquablement la théorie macroéconomique. Parmi les points les plus évoqués dans ce débat scientifique nous trouvons la question des rigidités qui caractérisent le marché des biens et services ainsi que le marché du travail ; les prix et salaires sont-ils rigides ou flexibles ? La réponse à cette question reste partagée entre différent courant de pensée économique. Pour les classiques et la nouvelle macroéconomie classique, la réponse est claire depuis Jean-Baptiste Say ; flexibilité retenue pour les marchés. Maintenant comment les prix et les salaires peuvent être rigides sur le court terme ? Quels sont les fondements microéconomiques et mathématiques de ces rigidités ? Ces questions sont le sujet crucial de la nouvelle macroéconomie Keynésienne. Comprendre les rigidités nous aidera à mieux comprendre la question d’arbitrage inflation-chômage, cette compréhension des rigidités explique la croissance de la courbe d’offre agrégée de court terme et sa fameuse équation, tel était notre sujetItem Gestion des taux de change: leçons a tirer pour les prochaines crises de change - L’experience de L’argentine (1991-2001) = The management of exchange rate : Lessons learned for the next crises of exchange - THE EXPERIENCE OF ARGENTINA (1991-2001)(Université M'Hamed Bougara Boumerdes /Laboratoire de recherche avenir de l’économie algérienne hors hydrocarbure, 2016) Chabani, Madjid; Abouderaz, SofianeThe Aim of this article to address the crisis of exchange experienced by Argentina in the late years of the nineties, because at that time of exchange followed the system, namely version funds regime between 1991 and 2001 it was the experience of Argentina of the most important experiences in the fight against hyper-inflation, as adopted in reducing inflation on the exchange-rate mechanism, through the adoption of the drainage system and the broker of the version type boxes so as to control the monetary version. It culminated in the three years that followed the application of this system a success in terms of inflation rates, decreased from 171.7% in 1991 to 4.2% in 1994, but with the occurrence of the Mexican financial crisis in 1994, suffered Argentina into financial trouble due to release funds system in itself and that made Argentine economy is very sensitive to external shocks, since a reduction in 1994 the Mexican peso, the Brazilian real in 1998, with the improvement in interest rates in the United States and the decline in unemployment in Europe and the United States in the mid-nineties. The global economic situation has created a kind of fear in the financial and monetary markets of a possible devaluation of the Argentine peso or the transition to a floating exchange rate. Wonder in this article all committed errors in setting rate policy in Argentina in 1991, and the extent of their contribution to the payment of the Argentine economy towards exchange crisis was possible avoided. This study help to clarify the weaknesses in the design and conduct of the exchange policy of the Argentine can even monetary policies and the policies of exchange-makers take advantage of them, and thus avoid falling into the same private exchange policy errorsItem The non-existence of an inflation-output trade-off under the rational expectations hypothesis as the cause of the steady state situation. Overtaking attempt(M'HAMED BOUGARA-BOUMERDES UNIVERSITY : Faculty of Economics, Commercial and Management Sciences, 2022) Abouderaz, SofianeThis article tries to prove the existence of an inflation-output (unemployment) trade-off, at least in the long-run, under a context of the rational expectations hypothesis REH, which makes it possible to overcome the Lucasian steady state situation. This existence of trade-off is due to the importance of saving and the accumulation of capital over time, but also to unexpected economic policies by the agents, which is effective to grow the economy. To achieve this objective, we will expose the unrealistic aspect of REH which avoids any inflation-output (unemployment) trade-off in the short-run and the long-run, and consequently it leads the economy to an infinite steady state situation. Our work undertakes a personal philosophical and mathematical approach, but which finds its origins in the pioneering works of economic growth theory, namely those of Harrod, Domar and Solow. we have tried to propose a solution for overcoming the steady state à la Lucas. our work requires further work to strengthen its theoretical and mathematical framework...or criticize it!Item Reflexion sur l’inflation algerienne (2000- 2012) : etude empirique(Université M'Hamed Bougara Boumerdes /Laboratoire de recherche avenir de l’économie algérienne hors hydrocarbure, 2013) Abouderaz, SofianeFor centuries, the money and its harmful impact on the economy, namely inflation, have aroused the intention of economists, and this intention becomes increasingly necessary because of the alarming rate of inflation registered in different economies. Today in Algeria, the inflation rates over the past two years have called for major analyzes dealing with its causes and effects, but its understanding is still ambiguous. We analyzed this inflation as an analysis tool of various monetary theories in order to better understand the real causes of evil and recommended for better solutions
