Migration and OECD service exports: an institutional perspective

Mardi | 2018-07-03 Salle des thĂšses 16h – 17h20 Isabelle RABAUD – Thierry BAUDASSE – Thierry MONTALIEU The relation between trade and migration is the subject of many controversies. Are substitutions or complementarities at stake? This paper aims to analyze the links between exports of services and immigration. Our sample concerns immigration from 191 countries towards 20 OECD countries in 2000, 2005 and 2010. We show that a higher share of individual country immigrants in the population tend to increase […]

Confidence Region for long memory based on Inverting Bootstrap Tests: an application to Stock Market Indices

Mardi | 2018-06-26 Salle Sully 5 16h – 17h20 Christian DE PERETTI – Carole SIANI In the context of long memory, the finite-sample distortion of statistic distributions is so large, that bootstrap confidence intervals (percentile and percentile-t) for the long memory parameter do not perform better than the corresponding asymptotic confidence interval. In this paper, we propose confidence intervals based on inverting bootstrap tests for the long memory parameter. Monte Carlo experiments are carried out for assessing the confidence intervals […]

On the consistency of the Z-score to measure the bank risk

Mardi | 2018-06-19 Salle des thĂšses 16h – 17h20 Ion LAPTEACRU This paper raises questions about the consistency of the Z-score, which is the most applied accounting-based measure of bank risk in the banking literature. In spite of its advantage, namely the concept of risk on which it relies, the traditional formula is precisely inconsistent with its own concept. The Z-score is deduced from the probability that bank’s losses exceed its capital, but under the very unrealistic assumption of normally […]

Constrained optimisation applied to Input/Output Table regionalisation with scarce data: application to La RĂ©union (France)

Mardi | 2018-06-12 Salle des thĂšses 16h – 17h20 JĂ©rĂ©my RODRIGUES – AurĂ©lie GAUDIEUX – Jacques VILLENEUVE Local data scarcity may lead Input-Output (I/O) analysts to build aggregated subnational models. Based on the case of the French economy, we claim that local I/O tables should instead be as detailed as the national ones. Any local data – never mind how aggregated – is more thoroughly used to adapt existing detailed national tables, than in an oversimplified model of the local […]

Structural Breaks and Herding Behaviour in Cryptocurrencies

Mardi | 2018-06-05 Salle des thĂšses 16h – 17h20 Dimitrios ASTERIOU – Kyriaki BEGIAZI Blockchain technology created cryptocurrencies. In January 2018, Bitcoin gained attention, as the most known electronic currency with the highest capitalisation. This paper examines the characteristics of the main cryptocurrencies (Bitcoin, Ethereum, Ripple, Litecoin, Stellar, NEM, Dash, Monero, Tether) from August 2015 to February 2018. Cryptocurrency index reported a structural break on January 2018, according to Chow breakpoint test. While Bitcoin was already on a steady decline […]

Geographical economics and income Disparities across Colombian Departamentos: Analysis for the period 1990-2015

Mardi | 2018-05-29 Salle des thĂšses 16h – 17h20 Jesus LOPEZ-RODRIGUEZ – Julian VASQUEZ-ROLDAN This paper focuses on the analysis of the role played by market potential in the spatial income structure observed in Colombia over the period 1990-2015. Based on the geographical economics theory we derive the so called nominal wage equation which establishes a relationship between nominal wages and a distance weighted sum of the volume of economic activities in surrounding locations which is usually known as market […]

Measuring Network Systemic Risk Contributions: A Leave-one-out Approach

Mercredi | 2018-05-24 Salle B103 – 12h00 Sullivan HUE – Sessi TOKPAVI – Yannick LUCOTTE Granger-causality measures of interconnectedness between financial institutions are useful indicators of systemic risk (Billio et al., 2012, Journal of Financial Economics), as they help to evaluate to which extent the distress of one institution disseminates across the whole financial system due to the network. This article provides a critical assessment of Granger-causality networks, showing that they can lead to inconsistent measures of systemic risk contributions […]

Trickle-Down Affirmative Action: A Case Study in Chess

Mardi | 2018-05-22 Salle B103 16h – 17h20 JosĂ© De SOUSA – Muriel NIEDERLE Vertical gender segregation is one of the most stubborn features of labor markets: high-ranking positions are primarily held by men in Business, Politics and Science. Can we implement pro-active steps to erase this segregation? We try to answer this question by investigating the effects of a clear affirmative action for women, where we have a good measure of “ability” even of people who did not directly […]

De l’hyperinflation au  » miracle monĂ©taire » : L’expĂ©rience hongroise de 1945-46

Mardi | 2018-05-15 Salle B103 16h – 17h20 Ludovic DESMEDT Entre août 1945 et juillet 1946, la Hongrie a connu la pire crise inflationniste jamais recensée. Dans les derniers jours de cet épisode, les prix augmentèrent de 150.000% par jour. Dès les travaux de Kaldor ou Nogaro sur cette expérience, plusieurs facteurs ont été mis en avant expliquer le phénomène : dérive des finances publiques, anticipations des acteurs ou introduction d’une monnaie indexée. L’objectif de cet article consiste à revenir […]

Voter Turnout and Intergenerational Redistribution

Mardi | 2018-04-24 Salle des thĂšses 16h – 17h20 Mickael MELKI Electoral reforms affecting the incentives to vote modify the composition of the electorate, potentially overrepresenting specific interests in policy implementation. Due to the age turnout gap, they may bias intergenerational redistribution in favor of the elderly. We exploit a natural experiment provided by the repeal of mandatory voting in Austria to study how a change in the incentive to vote affects intergenerational redistribution through pro-young public education spending. We […]
