We investigate the impact of exogenous local conditions which favor high market concentration on supply, price and quality in local markets for care homes for older people in England. We extend the existing literature in: (i) considering supply capacity as a market outcome alongside price and quality; (ii) taking account of the chain structure of care home supply and differences between the nursing home and residential care home sectors; (iii) using an econometric approach based on reduced form relationships that treats market concentration as a jointly determined outcome of a complex market. We find that areas susceptible to a high degree of market concentration tend to have greatly restricted supply of care home places and (to a lesser extent) a higher average public cost, than areas susceptible to low degree of market concentration. There is no significant evidence that conditions favoring high market concentration affect average care home quality.

英国养老院市场的市场集中度、供应、质量和地方当局支付的价格

我们调查了外生当地条件的影响，这些条件有利于英格兰老年人护理院当地市场的供应、价格和质量的高度集中。我们将现有文献扩展到：(i) 考虑供应能力作为市场结果以及价格和质量；(ii) 考虑到护理院供应链结构以及护理院和安老院部门之间的差异；(iii) 使用基于简化形式关系的计量经济学方法，将市场集中度视为复杂市场的共同确定结果。我们发现，与市场集中度低的地区相比，市场集中度高的地区往往会极大地限制养老院名额的供应，并且（在较小程度上）平均公共成本更高。
