The Changing Intra-Household Resource Allocation in Russia

During the transition toward a market economy, Russian workers have had to face important structural changes in the labour market as well as dramatic changes in their real earnings. In the process, the wage gap between men and women has varied wildly over that period. In recent years, young women have embraced professional careers, are more mobile on the labour market, and tend to delay the birth of their first child. All these trends are likely to influence intra-household relations and consequently the family decision process. To investigate this matter, we estimate a household collective labour supply model. We generalize the specification so as to allow the sharing rule to change in a discrete manner between the pre and post 1998 financial crisis periods. The parameters of the sharing-rule indicate that the households have shifted to a new equilibrium in the post-1998 period. Indeed, husbands have become more egotistic and wives more altruistic: an increase in their relative wage translates into a smaller/larger transfer to their spouse.Collective model, sharing rule, Russian economic crisis

How Do Spouses Share their Full Income ? Identification of the Sharing Rule Using Self-Reported Income

The paper applies the collective model to the analysis of intra-household inequality using self-reported income scales. Starting from a collective model including household production, our key assumption is that the income level that household members report corresponds to their true income sharing. Using Russian data (Rounds V to VIII of the Russian Longitudinal Monitoring Survey), we apply the results for couples who report the same level of income to identify the sharing rule for the whole sample. This method allows us to obtain not only the derivatives, but also the sharing rule itself. From simulations for an average couple with one child living in the Urals, we find that a full income share of 45% is allocated to the wife.Collective model, within-household income comparisons, subjective data, Russia, sharing rule.

Une analyse du partage intrafamilial du revenu à partir de données subjectives

Cette étude analyse l'inégalité intrafamiliale à l'aide de données subjectives. Nous utilisons une question relative au revenu individuel de chaque membre du ménage en faisant l'hypothèse que les réponses à cette question donnent une information pertinente sur le partage effectif du revenu au sein du ménage. A partir d'un modèle collectif incluant la production domestique, et en utilisant des données russes, le Russian Longitudinal Monitoring Survey, nous montrons que, conformément aux résultats du modèle, le rapport des taux de salaires entre les deux conjoints est un facteur déterminant dans l'explication des divergences dans les réponses quant au niveau de revenu entre les deux membres du couple. Nous trouvons également un effet significatif de la différence d'âge entre les conjoints.Répartition intrafamiliale, données subjectives, RLMS

How Do Spouses Share their Full Income in Russia?: Identification of the Sharing Rule Using Self-reported Income

The paper applies the collective model to the analysis of intra-household inequality using self-reported income scales and provides a test for its assumptions. We assume a correspondence between the income level that household members report and their true income sharing. Using Russian data, we first show that this assumption is supported by the data, and then use couples who report the same level of income to identify the full sharing rule for the whole sample. From simulations for an average couple living in the Urals, we find that a full income share of 45% is allocated to the wife.Collective model ; Within-household income comparisons ; Subjective data ; Russia ; Sharing rule

Polyelectrolyte multilayer formation: electrostatics and short-range interactions

We investigate the phenomenon of multilayer formation via layer-by-layer deposition of alternating charge polyelectrolytes. Using mean-field theory, we find that a strong short-range attraction between the two types of polymer chains is essential for the formation of multilayers. The dependence of the required short-range attraction on the polymer charge fraction and salt concentration is calculated. For weak short-range attraction between any two adjacent layers, the adsorbed amount (per added layer) decays as the distance from the surface increases, until the chains stop adsorbing altogether. For strong short-range attraction, the adsorbed amount per layer increases after an initial decrease, and finally it stabilizes in the form of a polyelectrolyte multilayer that can be repeated many times.Comment: 8 pages, 7 figure

Real-world efficacy of direct acting antiviral therapies in patients with HIV/HCV

The advent of direct-acting antiviral (DAA) therapies has dramatically transformed HCV treatment, with most recent trials demonstrating high efficacy rates (>90%) across all genotypes and special populations, including patients with HIV/HCV coinfection. The efficacy rates of HCV treatment are nearly identical between patients with HCV monofection and patients with HIV/HCV coinfection; however, there are limited studies to compare real-world efficacy with efficacy observed in clinical trials. Using a database from HIV clinics across the United States (US), we identified 432 patients with HIV/HCV coinfection who completed DAA therapy from January 1, 2014 to March 31, 2017 and were assessed for efficacy. Efficacy was evaluated as sustained virologic response (SVR) 12 weeks after DAA completion; furthermore, factors associated with achieving SVR12 were identified. In this analysis, we found DAA therapies to be effective, with 94% of the patients achieving SVR12 and 6% experiencing virologic failure. Baseline variables, including older age, HCV viral load <800K IU/ML, FIB-4 score <1.45, absence of depression, diabetes, substance abuse, and use of DAA regimens without ribavirin were significant predictors of achieving SVR12. Patients with fewer comorbidities, better liver health, and lower HCV viral loads at baseline were more likely to achieve treatment success. Our results were consistent with other real-world studies, supporting the use of HCV therapy in HIV/HCV coinfected patients

Grafted ionomer complexes and their effect on protein adsorption on silica and polysulfone surfaces

We have studied the formation and the stability of ionomer complexes from grafted copolymers (GICs) in solution and the influence of GIC coatings on the adsorption of the proteins β-lactoglobulin (β-lac), bovine serum albumin (BSA), and lysozyme (Lsz) on silica and polysulfone. The GICs consist of the grafted copolymer PAA28-co-PAPEO22 {poly(acrylic acid)-co-poly[acrylate methoxy poly(ethylene oxide)]} with negatively charged AA and neutral APEO groups, and the positively charged homopolymers: P2MVPI43 [poly(N-methyl 2-vinyl pyridinium iodide)] and PAH∙HCl160 [poly(allylamine hydrochloride)]. In solution, these aggregates are characterized by means of dynamic and static light scattering. They appear to be assemblies with hydrodynamic radii of 8 nm (GIC-PAPEO22/P2MVPI43) and 22 nm (GIC-PAPEO22/PAH∙HCl160), respectively. The GICs partly disintegrate in solution at salt concentrations above 10 mM NaCl. Adsorption of GICs and proteins has been studied with fixed angle optical reflectometry at salt concentrations ranging from 1 to 50 mM NaCl. Adsorption of GICs results in high density PEO side chains on the surface. Higher densities were obtained for GICs consisting of PAH∙HCl160 (1.6 ÷ 1.9 chains/nm2) than of P2MVPI43 (0.6 ÷ 1.5 chains/nm2). Both GIC coatings strongly suppress adsorption of all proteins on silica (>90%); however, reduction of protein adsorption on polysulfone depends on the composition of the coating and the type of protein. We observed a moderate reduction of β-lac and Lsz adsorption (>60%). Adsorption of BSA on the GIC-PAPEO22/P2MVPI43 coating is moderately reduced, but on the GIC-PAPEO22/PAH∙HCl160 coating it is enhanced
