We model purchaser–provider contracts when providers can inflate reimbursable activity through manipulation. Providers are audited and fined upon detected fraud. We characterise the optimal price and audit policy both in the presence and absence of commitment to an audit intensity. Under...

Performance indicators are increasingly used to regulate quality in health care and other areas of the public sector. We develop a model of contracting between a purchaser (principal) and a provider (agent) under the following scenarios: a) higher ability increases quality directly and...

We present a model of optimal contracting between a purchaser and a provider of health services. We assume that providers can increase demand by increasing quality but can also inflate activity through a manipulative effort (upcoding or DRG creep). We derive and compare the optimal price and...

The reproductive value (see Fisher 1930) arises as part of the shadow price of the population in a large class of age-structured optimal control models.

Abstract Increasing demand for long-term care poses at least five challenges to the policy-maker: (i) How should care be supplied, within a nursing home or within the family? (ii) What level of care should be provided in the different arrangements? (iii) How do the answers relate to the severity...

We assess the impact of population structure on economic growth. Following recent research, we focus on the generational turnover as a key driver of consumption growth. We characterize the impact of the average birth and death rates on the generational turnover, depending on the age-profile of...

We study the effects of a labor-intensive health care sector within an R&D-driven growth model with overlapping generations. Health care increases longevity and labor participation/productivity. We examine under which conditions expanding health care enhances growth and welfare. Even if the...
