Testing for Asymmetric Information in Insurance Markets: A Multivariate Ordered Regression Approach
2016
The positive correlation (PC) test is the standard procedure used in the empirical literature to detect the existence of asymmetric information in insurance markets. This article describes a new tool to implement an extension of the PC test based on a new family of regression models, the multivariate ordered logit, designed to study how the joint distribution of two or more ordered response variables depends on exogenous covariates. We present an application of our proposed extension of the PC test to the Medigap health insurance market in the United States. Results reveal that the risk–coverage association is not homogeneous across coverage and risk categories, and depends on individual so…
Does Environmental Uncertainty Affect Entrepreneurs’ Orientation and Performance? Empirical Evidence from Indonesian SMEs
2012
Small and medium enterprises (SMEs) have a critical role in economic growth in Indonesia and become the backbone for job creation, poverty alleviation, and safeguard during the crisis. However, they are highly exposed to uncertain environments. The present study aimed to investigate the influence of SMEs’ entrepreneurial orientation on business performance when uncertain environments exist. A total of 152 Indonesian SMEs were studied in order to assess this relationship. Moderated regression analysis is performed as the main statistical procedures to analyse the moderating role of environmental uncertainty on the influence of entrepreneurial orientation on business performance. Surprisingly…

DETECTING VOLCANIC ERUPTIONS IN TEMPERATURE RECONSTRUCTIONS BY DESIGNED BREAK-INDICATOR SATURATION
2016
We present a methodology for detecting breaks at any point in time-series regression models using an indicator saturation approach, applied here to modelling climate change. Building on recent developments in econometric model selection for more variables than observations, we saturate a regression model with a full set of designed break functions. By selecting over these break functions using an extended general-to-specific algorithm, we obtain unbiased estimates of the break date and magnitude. Monte Carlo simulations confirm the approximate properties of the approach. We assess the methodology by detecting volcanic eruptions in a time series of Northern Hemisphere mean temperature spanni…
Deconstrucción del “buen profesor”. Análisis de las características formales y no formales de la docencia universitaria
2016
Antecedentes: la evaluación de la calidad del profesorado universitario, desde el punto de vista del alumnado, se ha centrado principalmente en los aspectos más formales del ejercicio docente, desatendiendo así otros factores de tipo personal. Objetivo: identificar y analizar las cargas de cada uno de los distintos factores que conforman la idea de la buena docencia según el alumnado. Es decir, detectar la ecuación que da lugar al esquema mental de “buen profesor” o “buena profesora”. Método: encuesta transversal, elaborada a partir de los resultados de revisiones e investigaciones propias que permitieron conocer la identidad de los distintos factores implicados en la evaluación de la doce…
Prenatal exposure to mixtures of xenoestrogens and repetitive element DNA methylation changes in human placenta
2014
BACKGROUND: Prenatal exposure to endocrine disrupting compounds (EDCs) has previously shown to alter epigenetic marks. OBJECTIVES: In this work we explore whether prenatal exposure to mixtures of xenoestrogens has the potential to alter the placenta epigenome, by studying DNA methylation in retrotransposons as a surrogate of global DNA methylation. METHODS: The biomarker total effective xenoestrogen burden (TEXB) was measured in 192 placentas from participants in the longitudinal INMA Project. DNA methylation was quantitatively assessed by bisulfite pyrosequencing on 10 different retrotransposons including 3 different long interspersed nuclear elements (LINEs), 4 short interspersed nuclear …
Work-related and personal predictors of COVID-19 transmission: evidence from the UK and USA
2021
ObjectiveTo develop evidence of work-related and personal predictors of COVID-19 transmission.Setting and respondentsData are drawn from a population survey of individuals in the USA and UK conducted in June 2020.Background methodsRegression models are estimated for 1467 individuals in which reported evidence of infection depends on work-related factors as well as a variety of personal controls.ResultsThe following themes emerge from the analysis. First, a range of work-related factors are significant sources of variation in COVID-19 infection as indicated by self-reports of medical diagnosis or symptoms. This includes evidence about workplace types, consultation about safety and union memb…
Inequalities in mortality in small areas of eleven Spanish cities (the multicenter MEDEA project)
2009
The objectives of this study are to identify inequalities in mortality among census tracts of 11 Spanish cities in the period 1996-2003 and to analyse the relationship between these geographical inequalities and socioeconomic deprivation. It is a cross-sectional ecological study where the units of analysis are census tracts. We obtained an index of socioeconomic deprivation and estimated SMR by each census tract using hierarchical Bayesian models which take into account the spatial structure. In the majority of the cities geographical patterns in total mortality were found in both sexes, which were similar to those for the index of socioeconomic deprivation. Among men, four specific causes …
Adolescents' experiences of parental employment and parenting: connections to adolescents' well-being.
2004
This paper examines whether the relationship between parental work and adolescents' well-being would be mediated through parenting behaviour. The primary focus was on the experiences of adolescents. Questionnaire-based data from families (both parents and one children, n = 77) and adolescents (n = 126) were collected in Finland in 2000 and 2001, respectively. The adolescents were on average 14 years old. Results showed that the relationships between parents' negative work experiences and adolescents' depression (all perceived by adolescents) were partially mediated by adolescents' experience of lessened autonomy granting in parenting and increased conflicts between parents and adolescents. …
Automatic research of the capitalization rate for the residential automated valuation: an experimental study in Cosenza (Italy).
2017
When a market oriented approach is not applicable because of the lack of comparable sales data (Ciuna et al. 2014a), International Valuation Standards suggest the use of the Income Approach, which has the task of simulating the market through an economic and financial scheme. The central question of this approach is due to the quantification of the capitalization rate, whereas it is generally extracted in a market segment different from that of the subject. This paper intends to propose an automated valuation model of the capitalization rate based on a real estate database built through a computerized geocoding automatic procedure, starting from the application of statistical models of mult…
