Following the introduction of the long-term care insurance scheme and deregulation of the market for at-home care services, Japan experienced a substantial increase in expenditure on care for the elderly. Using household-level survey data, we empirically examine whether the increase in care expenditure is associated with supplier density springing from the rise in the number of care providers following deregulation. We provide weak evidence that supplier density in the at-home care market is positively correlated with probability to use care or expenditure on care. Moreover, we find no link between the share of for-profit providers and the demand for at-home care services.
