A bibliometric review of takaful literature
2020
Abstract Takaful (Islamic Insurance) achieved only recently a significant volume of academic research, despite its importance in addressing the insurance needs of Islamic societies and economies. We provide a thorough analysis of existing contributions on Takaful through a meta-literature methodology encompassing both a bibliometric (quantitative) and content (qualitative) analysis. By reviewing 69 articles, we aim at providing a rigorous background for the Islamic finance industry, its societies and economies, academic research and policymakers. We identify and review three leading research streams on Takaful: its overview, growth paths and models; governance mechanisms; products/services …
A bibliometric review of sukuk literature
2023
Abstract Sukuk (Islamic bonds) are one of the Islamic finance sectors that have experienced the fastest growth during the last decade. Using a quali-quantitative approach known as meta-literature review, the aim of this paper is to survey the sukuk literature over the period 1950–2018. In total we review and analyze 80 papers through bibliometric citation analysis (using HistCite and VOSviewer software) coupled with content analysis. We show the influential aspects of the literature, such as countries, institutions, journals, authors, articles and topics. We also present the co-authorship network and identify three research streams: (1) sukuk overview and growth, (2) sukuk and finance theor…
Ethnocentrism Effects on Consumers’ Behavior during COVID-19 Pandemic
2021
The COVID-19 pandemic has upset everyone’s normal daily activities, generating psychiatric disorders and changing consumers’ preferences. Among others, the agri-food sector has experienced strong changes and, during the lockdown period, Italian consumers modified their purchasing habits in response to the fear and uncertainty generated by the spread of the virus. In order to find out the main consequences of the shock suffered during the period and to understand which factors have affected purchasing choices, an online survey was conducted on 286 Italian consumers. The results show that ethnocentrism has been the factor that most has influenced consumers’ behavior during the lockdown period…
Path Dependence and Paradox in Harmonizing Out-of-court Procedures across Europe. The Evidence from Italy
2018
This paper focuses on the impact that the ‘new approach to business failure’ has had on Italian out-of-court procedures. It will demonstrate that in 2005 Italian law started to embrace the rescue culture of out-of-court procedures by means of a series of reforms; initially, this movement facilitated the incorporation of the ‘new approach to business failure’, but – and this is the paradox – the more law makers and courts remove the old paradigms and introduce new ones, which in principle could make the procedures smoother, cheaper and more efficient, the more the law in the book and the law in action appear to be overloaded with additional prerequisites which make the procedures cumbersome…
The 12th “Iter Mediterraneum” in Tunisia, 24 March – 4 April 2014
2015
The organization and logistics of the 12th OPTIMA Iter in Tunisia from 24 March to 4 April 2014 by OPTIMA and ATUTAX is here reported. The material used and the workflow are illustrated as reference for the organization of future similar collaborative botanical excursions.
Survey data and Bayesian analysis: a cost-efficient way to estimate customer equity
2014
We present a Bayesian framework for estimating the customer lifetime value (CLV) and the customer equity (CE) based on the purchasing behavior deducible from the market surveys on customer purchasing behavior. The proposed framework systematically addresses the challenges faced when the future value of customers is estimated based on survey data. The scarcity of the survey data and the sampling variance are countered by utilizing the prior information and quantifying the uncertainty of the CE and CLV estimates by posterior distributions. Furthermore, information on the purchase behavior of the customers of competitors available in the survey data is integrated to the framework. The introduc…
The continuous sample of working lives: Improving its representativeness
2017
This paper studies the representativeness of the Continuous Sample of Working Lives (CSWL), a set of anonymized microdata containing information on individuals from Spanish Social Security records. We examine several CSWL waves (2005–2013) and show that it is not representative for the population with a pension income. We then develop a methodology to draw a large dataset from the CSWL that is much more representative of the retired population in terms of pension type, gender and age. This procedure also makes it possible for users to choose between goodness of fit and subsample size. In order to illustrate the practical significance of our methodology, the paper also contains an applicatio…
Interactions, spillovers de connaissance et croissance des villes européennes. Faut-il préférer la géographie, le climat institutionnel ou les réseau…
2013
Knowledge spillovers within urban economies are also sources of spillovers between cities. We examine how knowledge spillovers influenced the economic growth of 82 European metropolises over the 1990-2005 period. We model knowledge spillovers between cities on the basis of five specific interaction patterns based on geography, networks of multinational firms in advanced services, institutional climate and two combinations of these factors. Spatial models are estimated to detail the effects of growth factors in terms of spillovers and externalities. We show that spillovers are local rather than global and that interactions among cities accelerate the convergence process based on gross value …
A Note on added information in the RAS Procedure: reexamination of some evidence
2006
International audience; An example in Miernyk (1977) presented a rather counterintuitive result, namely that introducing accurate exogenous information into an RAS matrix estimating procedure could lead to an estimate that was worse than one generated by RAS using no exogenous information at all. This became an oft-cited black mark against RAS. Miller and Blair (1985) included a different (and small) illustration of the same possibility. It was recently pointed out by one of us that the Miller/Blair numerical results are wrong. For that reason, we decided to reexamine all the empirical evidence we could find on the subject. While figures in both Miernyk and Miller/Blair appear to be wrong, …
Note about the concept of ‘Net Multipliers'
2002
International audience; Net multipliers, as introduced by Oosterhaven and Stelder (2002) accept outputs as entries instead of final demand. They are found by multiplying ordinary multipliers by the final demand ratio over the sector's output. This pragmatic solution suffers from ratio instability over time. The alternative net multipliers proposed here are based on the interpretation of the Leontief inverse matrix for the effects generated at each round. The new solution is not sensitive to the size of impacts. Now net multiplier is equal to the corresponding ordinary multiplier minus one, and the ordering of multipliers is unchanged.
