Family networks and healthy behaviour: evidence from Nepal.

Models of household decision-making commonly focus on nuclear family members as primary decision-makers. If extended families shape the objectives and constraints of households, then neglecting the role of this network may lead to an incomplete understanding of health-seeking behaviour. Understanding the decision-making processes behind care-seeking may improve behaviour change interventions, better intervention targeting and support health-related development goals.

Testing consumer theory: evidence from a natural field experiment.

We present evidence from a natural field experiment designed to shed light on whether individual behavior is consistent with a neoclassical model of utility maximization subject to budget constraints. We do this through the lens of a field experiment on charitable giving. We find that the behavior of at least 80% of individuals, on both the extensive and intensive margins, can be rationalized within a standard neoclassical choice model in which individuals have preferences, defined over own consumption and their contribution towards the charitable good, satisfying the axioms of revealed preference.

Clinical and radiological responses after infliximab treatment for perianal fistulizing Crohn's disease.

Objectives: Infliximab is an effective therapy for fistulizing Crohn's disease of the perineum. We sought to determine whether the clinical improvement after infliximab is associated with radiological closure of fistula tracts.

Methods: Clinical responses and radiological imaging studies by transperineal ultrasound were evaluated in 35 patients with Crohn's disease perianal fistulas after treatment with infliximab 5 mg/kg up to 48 wk.
