Social capital and self‐rated health in Argentina
利用阿根廷全国调查数据，以非正式社交互动衡量社会资本，并用公共交通可达性作为工具变量，发现社会资本水平更高的人自评健康更好。
The potential link between social capital and health suggests important pathways by which health may be improved. We examine this relationship using a unique data set from Argentina. This national survey allows us to determine whether the relationships between social capital and health that have been found in the US and Europe also apply to countries in South America (Argentina is the second-largest country in South America with a population of approximately 40 million). We estimate a causal effect of individual-level social capital on health using a measure of informal social interactions as our measure of social capital. Using information about access to public transportation as instrumental variables, we find that both men and women with higher levels of social capital report better health.
