AbstractThere has been substantial consolidation among health insurers and hospitals, recently, raising questions about the effects of this consolidation on the exercise of market power. We analyze the relationship between insurer and hospital market concentration and the prices of hospital services. We use a national US dataset containing transaction prices for health care services for over 11 million privately insured Americans. Using three years of panel data, we estimate how insurer and hospital market concentration are related to hospital prices, while controlling for unobserved market effects. We find that increases in insurance market concentration are significantly associated with decreases in hospital prices, whereas increases in hospital concentration are non-significantly associated with increases in prices. A hypothetical merger between two of five equally sized insurers is estimated to decrease hospital prices by 6.7%.

Social exclusion remains the most visible expressions of slum settlements. This study investigates the expression of social exclusion and survival strategies among slum dwellers in Ibadan, Nigeria. A merger of Burgess’ concentric zone model and conflict theory formed the theoretical orientation for this study. Data were gathered through triangulation of quantitative and qualitative methods. In all, semi-structured questionnaire was administered to 400 respondents and 10 in-depth interviews were conducted among residents in Bere slum. Among others, lack of access to formal employment (98.0%), modern health care facilities (91.0%), consultation of government officials to know needs (92.2%), adequate shelter (100%), were the most mentioned challenges. Major survival strategies adopted were hawking, child labour, prostitution, stealing and gambling. Also, due to a lack of modern health care services in the area, self-medication (61.0%), traditional method of treatment (27.5%), and faith healing (11.5%) were most mentioned strategies adopted to cope with health challenges in the area. This paper therefore concludes that social inclusion of slum inhabitants in all government welfare services and decision making process should be advocated, as a means of reducing the rates of poverty and crime in Ibadan.

This study analyses the effect of spatial concentration of general hospitals, the appearance of independent treatment centers (in Dutch: Zelfstandige Behandelcentra: ZBCs) and the concentration of health insurers on production volume and costs since the introduction of market-oriented health care reforms in the Netherlands. We use regression analyses of 1,345,144 patient-level hospital data for fifteen major diagnosis treatment combinations (in Dutch: Diagnose Behandeling Combinaties: DBCs), representing 70% of the managed competition segment (the so-called B-segment). We find that spatial concentration of hospitals and concentration of insurers do not affect health care production volume. More competitive hospital markets are associated with higher cost of most DBCs studied. Surprisingly, hospitals operating under insurers with high monopsonic power incur higher average DBC-cost than hospitals operating under insurers with more dispersed power. The number of independent treatment centers in the hospital’s vicinity is positively related to health care volume and average cost.
