Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample
2017
While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model …
Validation of the Weight Bias Internalization Scale for Mainland Chinese Children and Adolescents
2021
Weight stigma internalization among adolescents across weight categories leads to adverse psychological consequences. This study aims to adapt and validate a Chinese version of the Weight Bias Internalization Scale for Mainland Chinese children and adolescents(C-WBIS). A total of 464 individuals aged 9 to 15 years participated in the present study. Based on item response theory (IRT) and classical test theory (CTT), we selected the items for the C-WBIS and evaluated its reliability and validity. The item response theory yields support for the one-dimensional factor mode. All item parameters fit the IRT model (albeit within an adequate range), eight items were adopted. No evidence of signifi…
Automated Valuation Methods in Atypical Real Estate Markets Using the Mono-parametric Approach
2017
The appraisal objectivity depends on the possibility to quickly and easily access to reliable real estate data in order to apply appropriate appraisal approaches. In order to ensure the objectivity of the real estate appraisals, in recent years Automated Valuation Methods (AVM) have been developed, integrating computerized real estate databases and programming languages. The Automated Valuation Methods proposed at international level usually recur to regression models, aimed to return appraisal equations based on reliable real estate databases. This approach is not applicable in some markets where lack of data does not allow the implementation of regression models. This paper proposes to im…
Modeling Conditional Skewness in Stock Returns
2007
Abstract In this paper, we propose a new GARCH-in-Mean (GARCH-M) model allowing for conditional skewness. The model is based on the so-called z distribution capable of modeling skewness and kurtosis of the size typically encountered in stock return series. The need to allow for skewness can also be readily tested. The model is consistent with the volatility feedback effect in that conditional skewness is dependent on conditional variance. Compared to previously presented GARCH models allowing for conditional skewness, the model is analytically tractable, parsimonious and facilitates straightforward interpretation.Our empirical results indicate the presence of conditional skewness in the mon…
Do Large European Banks Differ in their Derivative Disclosure Practices? A Cross-country Empirical Study.
2019
Risk disclosure has strategic importance for the efficiency of financial markets and overall financial stability. It plays a pivotal role in strengthening market discipline and building trust to improve relationships with stakeholders in banking. Risk reporting has taken a growing importance in banking over the last years. The topic of this paper is derivative reporting in banking. The authors employ content analysis to conduct an empirical study on a sample of large European banks. The authors propose a hybrid scoring model for the assessment of derivative disclosure in banking institutions. The methodology employed in this research is able to capture a considerable amount of information b…
Financial Structure of the Family Business: Evidence From a Group of Small Spanish Firms
2007
This article presents empirical evidence on the determinants of the financial behavior of small family businesses and their differences from nonfamily small businesses. Taking into account two consolidated financial approaches, (1) the trade-off theory and (2) the pecking order theory, several hypotheses on the financial behavior of both groups of firms have been tested. By estimating these models through panel data methodology, using a sample of Spanish family businesses together with another control group of nonfamily businesses, we have obtained results confirming that a business's family nature does lead it to employ financial policy different from the rest of businesses. Furthermore, …
Early warning of systemic risk in global banking: eigen-pair R number for financial contagion and market price-based methods
2021
AbstractWe analyse systemic risk in the core global banking system using a new network-based spectral eigen-pair method, which treats network failure as a dynamical system stability problem. This is compared with market price-based Systemic Risk Indexes (SRIs), viz. Marginal Expected Shortfall (MES), Delta Conditional Value-at-Risk (Delta-CoVaR), and Conditional Capital Shortfall Measure of Systemic Risk (SRISK) in a cross-border setting. Unlike paradoxical market price based risk measures, which underestimate risk during periods of asset price booms, the eigen-pair method based on bilateral balance sheet data gives early-warning of instability in terms of the tipping point that is analogou…
A Note on Laws of Motion for Aggregate Distributions
2020
I derive the law of motion for the aggregate distribution directly from the laws of motion for the individuals’ states. By relying on concepts from measure theory, the derivation is concise and intuitive. I address random shocks both at the micro level and at the macro level. Micro-level shocks completely cancel at the aggregate level provided that a law of large numbers applies. Therefore, the law of motion for the aggregate distribution is a deterministic process in the absence of macro-level uncertainty. If there are macro-level risks, the law of motion for the aggregate distribution exhibits a stochastic component additionally. I illustrate the formalism in a model of wealth accumulatio…
The Impact of Board Internationalization on Earnings Management
2016
Prior literature shows that choices regarding board composition are associated with earnings management. We add to this literature by examining the effects of the presence of a foreign board member on earnings management. Using a sample of 3,249 firm-year observations representing 586 non-financial listed Nordic firms during 2001-2008, we find that the presence of a non-Nordic, foreign director is associated with significantly higher levels of earnings management. Moreover, we provide preliminary evidence that differences in accounting knowledge drive this effect. Our results suggest that it may not necessarily be beneficial to appoint a foreign director to the board.
Informal, formal institutions and credit: complements or substitutes?
2019
AbstractThis paper analyses the relationship between informal institutions measured by social trust and the provision of private credit. Research on the trust–finance relationship abounds, although most of it is confined to the micro-level, with far fewer contributions from a wide, cross-country perspective. Considering a sample of 119 economies in the period 1993–2015, results suggest that social trust is an important determinant of private credit, and that its effects are transmitted indirectly via some particular aspects of the quality of economic-judicial institutions. In addition, and contrary to previous findings in related areas, substitutive effects for informal and formal instituti…
