Does Shariah compliance make interest rate sensitivity of Islamic equities lower? An industry level analysis under different market states
2018
This paper examines the sensitivity of the Dow Jones Islamic market index and its corresponding industry equity indices to changes in the level, slope and curvature of the U.S. term structure of in...
On the severity of economic downturns: Lessons from cross-country evidence
2012
Abstract We measure the severity of recessions as a function of their amplitude and duration. Within a quantile regression framework, we assess what causes economic downturns to be more or less severe. We find that the most severe downturns have striking similarities regarding cumulated domestic credit and large current account deficits.
Urban segregation and unemployment: A case study of the urban area of Marseille – Aix-en-Provence (France)
2018
International audience; In this paper, we study the effects of the spatial organization of the urban area of Marseille – Aix-en-Provence on unemployment there. More specifically, differences in the characteristics of the residential population induce urban stratification with the result that urban structure may affect the probability of employment. In order to evaluate the effects of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. Our results support the hypothesis that living in or near a deprived neighborhood decreases the probability of employment.
Do commodity assets hedge uncertainties? What we learn from the recent turbulence period?
2022
AbstractThis study analyses the impact of different uncertainties on commodity markets to assess commodity markets' hedging or safe-haven properties. Using time-varying dynamic conditional correlation and wavelet-based Quantile-on-Quantile regression models, our findings show that, both before and during the COVID-19 crisis, soybeans and clean energy stocks offer strong safe-haven opportunities against cryptocurrency price uncertainty and geopolitical risks (GPR). Soybean markets weakly hedge cryptocurrency policy uncertainty, US economic policy uncertainty, and crude oil volatility. In addition, GSCI commodity and crude oil also offer a weak safe-haven property against cryptocurrency uncer…
Improved Planning In-Service Inspections of Fatigued Aircraft Structures Under Parametric Uncertainty of Underlying Lifetime Models
2014
Certain fatigued structures must be inspected in order to detect fatigue damages that would otherwise not be apparent. A technique for obtaining optimal inspection strategies is proposed for situations where it is difficult to quantify the costs associated with inspections and undetected failure. For fatigued structures for which fatigue damages are only detected at the time of inspection, it is important to be able to determine the optimal times of inspection. Fewer inspections will lead to lower fatigue reliability of the structure upon demand, and frequent inspection will lead to higher cost. When there is a fatigue reliability requirement, the problem is usually to develop an inspection…
The Effect of Systemic Banking Crises on Entrepreneurship
2014
Economic crises have mixed effects on entrepreneurship. Through demand shocks, credit constraints, and unemployment, systemic banking crises affect the rate of start-up business creation, although the extent of their impact varies. Consequently, previous studies on the effect of crises on Entrepreneurship are inconclusive. The surge of global demand coupled with low credit availability reduces the prospects for new businesses. On the other hand, job losses caused by an economic crisis might lead many entrepreneurs to undertake new projects. These inconsistent conclusions highlight the need for more studies that explore the effect of systemic banking crises on entrepreneurship. This article …
Investigating the role of environmental taxes and regulations for renewable energy consumption: evidence from developed economies
2021
The current study aims to explore the role of environmental taxes and regulations for the renewable energy consumption, focusing on reporting policy suggestions to overcome climate change issues and achieve environmental sustainability. The main objective of this paper is to examine the relation between renewable energy, environmental taxes, environmental technologies, and environmental regulations in 29 OECD countries during 1996–2018. More precisely, we inspect the impact of the environmental regulations and environmental technologies on the renewable energy consumption. The authors employ CIPS and CADF unit root tests, panel Westerlund co-integration test, FMOLS, and Quantile regression …
Estimation de la relation de salaires de Mincer : choix de specification et enjeux économétriques
2012
In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrum…
Nonparametric estimation of quantile versions of the Lorenz curve

Quantile estimation via distribution fitting
2019
This paper focuses on nonparametric estimation of quantiles, based on estimators of the distribution function. We review some known and recommended quantile estimators and propose a new one, which has all the desired properties of quantile estimators. The consistency and asymptotic normality of the estimators is proved. The estimators considered are compared in a small simulation study.
