Exploiting a rich data set on the Dutch market for home help services, we find that larger providers obtain a higher price than do small providers. However, compared to other studies on market power in care markets this price difference is considered small to moderate. Our identification strategy relies on the exogenous variation in market shares in January'07, the very first month after home help was decentralized to municipalities. Zooming in on our main outcome, we obtain that the small but significant effect of market size on price is merely driven by the pricing behavior of for-profit providers.
利用荷兰家庭帮助服务市场的丰富数据集，我们发现较大的供应商比较小的供应商获得更高的价格。然而，与其他关于护理市场市场力量的研究相比，这种价格差异被认为是小到中等的。我们的识别策略依赖于2007年1月（家庭帮助服务下放到各市后的第一个月）市场份额的外生变化。深入研究我们的主要结果，我们发现市场规模对价格的微小但显著的影响仅仅是由营利性供应商的定价行为驱动的。
