Sustainable Financing of Innovative Therapies: A Review of Approaches

The process of innovation is inherently complex, and it occurs within an even more complex institutional environment characterized by incomplete information, market power, and externalities. There are therefore different competing approaches to supporting and financing innovation in medical technologies, which bring their own advantages and disadvantages. This article reviews value- and cost-based pricing, as well direct government funding, and cross-cutting institutional structures. It argues that performance-based risk-sharing agreements are likely to have little effect on the sustainability of financing; that there is a role for cost-based pricing models in some situations; and that the push towards longer exclusivity periods is likely contrary to the interests of industry

Capital social en áreas rurales: adaptación al español y validación factorial de una escala

El capital social se considera un determinante estructural de desarrollo y bienestar social. Su componente cognitivo evalúa el grado de confianza de la población en sus sistemas de organización social, así como las interacciones comunitarias que estructuran respuestas sociales a los problemas sociales. Existen pocas escalas disponibles para la medición de este constructo. Este trabajo presenta los resultados de la adaptación al español y validación psicométrica de una escala para la medición de capital social en contextos rurales. Se adaptó al español la escala de capital social cognitivo de Wang. Se aplicaron 1200 cuestionarios a adultos en 12 veredas de Tierralta (Colombia) seleccionados con muestreo aleatorio simple estratificado. Se realizó análisis factorial de la escala a partir de una matriz de correlación policórica. El análisis factorial exploratorio sugiere la existencia de dos factores principales distribuidos así: 7 ítems para el factor 1 (confianza) (valor propio 3.23.) y 2 ítems para el factor 2 (desconfianza) (valor propio 1.40). Como fue observado por Wang, Q9 y Q10 parecen preguntas ambiguas que no aportan suficiente a ninguno de los factores. Se presenta la primera validación factorial al español de la escala de capital social de Wang en el contexto social de la Colombia rural

Social capital and health: Does egalitarianism matter? A literature review

The aim of the paper is to critically review the notion of social capital and review empirical literature on the association between social capital and health across countries. The methodology used for the review includes a systematic search on electronic databases for peer-reviewed published literature. We categorize studies according to level of analysis (single and multilevel) and examine whether studies reveal a significant health impact of individual and area level social capital. We compare the study conclusions according to the country's degrees of economic egalitarianism. Regardless of study design, our findings indicate that a positive association (fixed effect) exists between social capital and better health irrespective of countries degree of egalitarianism. However, we find that the between-area variance (random effect) in health tends to be lower in more egalitarian countries than in less egalitarian countries. Our tentative conclusion is that an association between social capital and health at the individual level is robust with respect to the degree of egalitarianism within a country. Area level or contextual social capital may be less salient in egalitarian countries in explaining health differences across places

Who Believes in Me? The Effect of Student-Teacher Demographic Match on Teacher Expectations

Teachers are an important source of information for traditionally disadvantaged students. However, little is known about how teachers form expectations and whether they are systematically biased. We investigate whether student-teacher demographic mismatch affects high school teachers’ expectations for students’ educational attainment. Using a student fixed effects strategy that exploits expectations data from two teachers per student, we find that non-black teachers of black students have significantly lower expectations than do black teachers. These effects are larger for black male students and math teachers. Our findings add to a growing literature on the role of limited information in perpetuating educational attainment gaps
