An ex-post control could be carried out in a sample of hospitals to address this limitation.
Generally speaking, the lab director continues, we can see again a confusion between two very different concepts and related procedures: "ex-ante regulation" vs. "ex-post controls".
Consistent with an alleviation of moral hazard problems, tighter capital expenditure restrictions (performance covenants) are more likely to facilitate ex post creditor control through covenant renegotiations (violations).

In the absence of a randomised control trial, instrumental variables methodology acts as an ex post randomisation and enables us to estimate the 'causal effects' of designation and volume of neonatal care provided at the hospital of birth.
For ex post evaluation, the following estimation methods are discussed: traditional regression methods, matching, control function methods, instrumental variable and local instrumental variable (LIV) methods, and regression-discontinuity.
Most organizational mechanisms fail to control that type of opportunism because of information asymmetries, even ex post.
Thus, there is always an indirect flow of goods and services, rendering health care environments and all of their participants very susceptible to known quality control as well as economic dilemmas (e.g. principal agent, ex post and ex ante moral hazard, adverse selection, information asymmetry).
