In this chapter, we argue that good experimental design and analysis accounts for the notion of construal, a person's subjective interpretation of a stimulus, a situation, or an experimental intervention. Researchers have long been aware of motivations, such as self-presentation, profit seeking,...

Between 1970 and the early 2000s, there was a revolution in support for the use of field experiments to evaluate social programs. Focusing on the welfare reform studies that helped to speed that transformation in the United States, this chapter describes the major challenges to implementing...

In this chapter, we present econometric and statistical methods for analyzing randomized experiments. For basic experiments, we stress randomization-based inference as opposed to sampling-based inference. In randomization-based inference, uncertainty in estimates arises naturally from the random...

A number of critical innovations spurred the rapid expansion in the use of field experiments by academics. Some of these were econometric but many were intensely practical. Researchers learned how to work with a wide range of implementing organizations from small, local nongovernmental...

This essay reviews the ways in which field experiments have been used to study political participation. We begin by charting the intellectual history of field experimentation in political science. We explain why the advent of field experimentation in recent years represents an important advance...

This is a review of the literature of field experimental studies of markets. The main results covered by the review are as follows: (1) Generally speaking, markets organize the efficient exchange of commodities; (2) There are some behavioral anomalies that impede efficient exchange; (3) Many...

A modern, decision-theoretic framework can help clarify important practical questions of experimental design. Building on our recent work, this chapter begins by summarizing our framework for understanding the goals of experimenters and applying this to rerandomization. We then use this...
