Mardi | 2019-12-03 Salle des thèses 16h – 17h20 Hendrik KRUSE – Thais NUNEZ-ROCHA – Camélia TURCU In this paper, we investigate the claim that rich countries use development aid to ensure access to natural resources. We provide a theoretical model that suggests that even an altruistic donor may be inclined to allocate a higher share of their aid expenditure on infrastructure and other trade promoting measures if they rely on the recipient’s resource exports for their own production. We […]

Mardi | 2019-11-26 Salle des thèses 16h – 17h20 Franck JOVANOVIC Le séminaire a pour objectif de montrer le rôle précurseur du LEO, et en particulier de Georges Gallais-Hamonno, dans l’introduction de l’économie financière en France parmi les économistes français au milieu des années 1970. L’Institut orléanais de finance, ancêtre du LEO, est en effet le premier laboratoire français à une époque où cette discipline est délaissée par les économistes français, laissant le champ libre aux gestionnaires français pendant plus […]

Mardi | 2019-11-05 Salle des thèses 16h-17h20 Financial institutions increasingly rely on predictive machine learning models to detect fraudulent transactions. Two main challenges when building a supervised tool for fraud detection are the imbalance or skewness of the data and the various costs for different types of miscalissification. We discuss techniques to solve the imbalance issue and present a cost-sensitive logistic regression algorithm.

Mercredi | 2019-10-24 Salle B103 – 12h00 Tobignaré YABRE This paper analyses the growth effect of various components of public expenditure in interaction with numerical fiscal rules. We estimate a dynamic panel model for 92 developed and developing countries using a Generalized Method of Moments (GMM) technique. We provide a more systematic empirical evidence than available hitherto defending that the adoption of a fiscal rule generates a shift on the composition of government expenditure that may increase the growth rate. […]

Mardi | 2019-10-22 Salle des thèses 16h – 17h20 We provide a bank-run model in which confidence is proxied by the noise around the estimation by depositors of the distribution of the asset portfolio of their bank in t = 0. The probability that a bank i experiences a run in t = 1 depends on the realized returns of the other banks due to informational and balance sheet linkages between financial institutions. Low confidence is found to foster informational […]

Mercredi | 2019-10-10 Salle B103 – 12h00 Hugo ORIOLA The literature dealing with the political impact on monetary authority is marked by an ongoing discussion. This paper aims to prove that politically induced cycles in the monetary policy called political monetary cycles (PMC) exist in reality. We find evidence that such a phenomenon is observable in both developed and developing countries. Moreover, this result is confirmed regardless the level of independence of the central bank. In addition, we examine if […]

Mardi | 2019-10-08 Salle des thèses 16h – 17h20 Colombe LADREIT DE LACHARRIèRE – Jérémie COHEN-SETTON – Egor GORNOSTAY This paper estimates the effects of fiscal stimulus on economic activity using a novel database on large fiscal expansions for 17 OECD countries for the period 1960–2006. The database is constructed by combining the statistical approach to identifying large shifts in fiscal policy with narrative evidence from contemporaneous policy documents. When correctly identified, large fiscal stimulus packages are found to have […]

Mercredi | 2019-09-26 Salle B103 – 12h00 Robert Christian Serge MEBENGA M’ENAM Nous nous proposons dans ce travail, d’estimer une règle opérationnelle de conduite permettant aux responsables de la BEAC de préserver la stabilité des prix tout en limitant les écarts du PIB par rapport à sa cible. Pour ce faire, nous optimisons une fonction-objectif conforme au mandat de la BEAC. Nous dérivons ensuite le taux d’inflation optimal et effectuons des simulations sur le paramètre d’arbitrage entre la variabilité de […]

Mardi | 2019-09-24 Salle des thèses 16h – 17h20 Isabelle RABAUD – VOLKER NITSCH Terrorist events typically vary along many dimensions, making it difficult to identify their economic effects. This paper analyzes the impact of terrorism on international trade by examining a series of three large-scale terrorist incidents in France over the period from January 2015 to July 2016. Using firm-level data at monthly frequency, we document an immediate and lasting decline in cross-border trade after a mass terrorist attack. […]
