Incentive and Selection Effects of Medigap Insurance on Inpatient Care
2012
The Medicare program, which provides insurance coverage to the elderly in the United States, does not protect them fully against high out-of-pocket costs. For this reason private supplementary insurance, named Medigap, has been available to cover Medicare gaps. This paper studies how Medigap affects the utilization of inpatient care, separating the incentive and selection effects of supplementary insurance. For this purpose, we use two alternative estimation methods: a standard recursive bivariate probit and a discrete multivariate finite mixture model. We find that estimated incentive effects are modest and quite similar across models. On the other hand, there seems to be very significant …
Mecanismos de atenuación entre el decir y lo dicho: procesos de enunciación a través de la partícula discursiva digamos
2018
Este trabajo presenta los resultados obtenidos en el análisis de la partícula discursiva digamos en corpus coloquiales (Val.Es.Co. 2002 y 2.0.), aplicando el sistema de unidades, niveles y posiciones Val.Es.Co. (Briz y grupo Val.Es.Co. 2003, 2014) y la ficha Es. Por. Atenuación (Albelda et alii 2014). El resultado integra dos perspectivas de análisis para determinar si factores como la unidad ocupada o posición discursiva condicionan su polifuncionalidad. This study presents the results obtained from the analysis of the Spanish discourse particle digamos in colloquial corpus. The Val.Es.Co. proposal (Briz et alii 2003, 2014) and the Es.Var.Atenuación analysis sheet (Albelda et alii 2014) ar…
Risk Preference Heterogeneity and Multiple Demand for Insurance
2010
We examined the relationship between unobserved risk preferences and four insurance purchase decisions: health Medigap insurance, long-term insurance, life insurance and annuity. Standard economic theory assumes that individuals take decision over a set of risky domains according to their own risk preferences which are stable across decision contexts. This assumption of context-invariant risk preference has caused debate in the literature concerning its validity. Using data from the Health and Retirement Study, we exploit latent class analysis to identify conditional on predicted and realized risk how heterogeneity in risk preferences affects multiple insurance demand. Our results provide e…
SPOSTAMENTI DELLA SPONDA DI UN LAGO ARTIFICIALE CAUSATI DA CARSISMO DA DISSOLUZIONE DEI GESSI
2013
Il serbatoio Disueri sul F. Gela è stato creato con una diga di muratura a secco, completata nel 1948, sostituita nel 1997 con una diga di terra. Entrambe le dighe sono fondate su rocce della serie Gessoso-Solfifera che nella zona di sbarramento è interessata da pieghe e faglie che dànno luogo a un assetto strutturale estremamente complesso. Sulla sponda sinistra affiora un banco di gessi selenitici interessato da numerose cavità, parecchie delle quali di grandi dimensioni. L’evoluzione delle cavità è rapida a causa dell’alta velocità di dissoluzione dei gessi in condizioni di acqua fluente, e ha dato origine a una grande conca di subsidenza e a spostamenti che lasciano prefigurare la forma…
Testing for Asymmetric Information in Insurance Markets: A Multivariate Ordered Regression Approach
2018
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…

Interaction between Medicago truncatula and the pathogenic oomycete Aphanomyces euteiches: effects of nitrogen nutrition and plant genotype
2015
Plants are under the constant threat of microbial pathogens. To defend themselves, plants have developed immune responses (including for example synthesis of antimicrobial secondary metabolites, production of PR proteins or reinforcement of cell wall) that can lead to resistance. However, these plant defense responses are costly and lead plants to continuously face a dilemma regarding the partitioning of their available resources. In order to better understand relationships between plant nutrition and defense, we analyzed the impact of nitrogen (N) nutrition on the capacity of different M. truncatula genotypes to resist against A. euteiches, the causal agent of legume root rot disease. N st…
MONITORAGGIO DI OPERE STRATEGICHE MEDIANTE TECNICHE SATELLITARI: IL CASO STUDIO DELLA DIGA “CASTELLO SUL FIUME MAGAZZOLO”
2017
Il Global Navigation Satellite System (GNSS) e il telerilevamento sono stati utilizzati per determinare la relazione tra le deformazioni di una diga di terra e le variazioni di superficie e livello di invaso, durante il periodo di un anno. L’utilizzo di un ricevitore posto sul coronamento della diga e di una stazione permanente attivi durante l’arco della giornata ha permesso la determinazione della serie temporale degli spostamenti dell’opera nel periodo analizzato, riferiti ad un sistema di riferimento locale della diga. La componente ortogonale al coronamento è stata successivamente posta in relazione con le forze di natura idraulica che agiscono sull’opera. Per la determinazione dei liv…
Reactions of Terphenyl-Substituted Digallene AriPr4GaGaAriPr4 (AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) with Transition Metal Carbonyls and Theoretical In…
2016
The neutral digallene AriPr4GaGaAriPr4 (AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) was shown to react at ca. 25 °C in pentane solution with group 6 transition metal carbonyl complexes M(CO)6 (M = Cr, Mo, W) under UV irradiation to afford compounds of the general formula trans-[M(GaAriPr4)2(CO)4] in modest yields. The bis(gallanediyl) complexes were characterized spectroscopically and by X-ray crystallography, which demonstrated that they were isostructural. In each complex, the gallium atom is two-coordinate with essentially linear geometry, which is relatively rare for gallanediyl-substituted transition metal species. The experimental data show that the gallanediyl ligand :GaAriPr4 behaves as a g…
