<Abstract>
We describe a new design-based framework for drawing causal inference in
randomized experiments. Causal effects in the framework are defined as
linear functionals evaluated at potential outcome functions. Knowledge and
assumptions about the potential outcome functions are encoded as function
spaces. This makes the framework expressive, allowing experimenters to
formulate and investigate a wide range of causal questions. We describe a
class of estimators for estimands defined using the framework and
investigate their properties. The construction of the estimators is based
on the Riesz representation theorem. We provide necessary and sufficient
conditions for unbiasedness and consistency. Finally, we provide conditions
under which the estimators are asymptotically normal, and describe a
conservative variance estimator to facilitate the construction of
confidence intervals for the estimands.
