This means there may be systematic differences between the groups. Quasi-experiments, like all experiments, manipulate treatments to determine causal effects (quasi-experiments are sometimes referred to as nonrandomized … Quasi-experimental designs relax some of the key requirements of true experiments, making them more practical to implement in many cases but also reducing the strength of the causal claims that can be made.

We begin with two observations: (i) standard quasi-experimental methods, first applied in other microeconomic fields, typically assume unit-level treatments that do not spill over across units; (ii) because public goods, such as environmental attributes, exhibit externalities, treatment of one unit
