    Formal analysis plans limit false discoveries by registering and multiplicity adjusting statistical tests. As each registered test reduces power on other tests, researchers prune hypotheses based on prior knowledge, often by combining related indicators into evenly-weighted indices. We propose two improvements to maximize learning within these types of analysis plans. First, we develop data-driven optimized indices that can yield more powerful tests than evenly-weighted indices. Second, we discuss organizing the logical structure of an analysis plan into a gated tree that directs type I error towards these high-powered tests. In simulations we show that researchers may prefer these "optimus gates" across a wide range of data-generating processes. We then assess our strategy using the community-driven development (CDD) application from Casey et al. (2012) and the Oregon Health Insurance Experiment from Finkelstein et al. (2012). We find substantial power gains in both applications, meaningfully changing the conclusions of Casey et al. (2012)

  4. Reinforcing RCTs with Multiple Priors while Learning about External Validity
    Erschienen: 2022
    Verlag:  National Bureau of Economic Research, Cambridge, Mass

    This paper presents a framework for how to incorporate prior sources of information into the design of a sequential experiment. These sources can include previous experiments, expert opinions, or the experimenter's own introspection. We formalize... mehr

    This paper presents a framework for how to incorporate prior sources of information into the design of a sequential experiment. These sources can include previous experiments, expert opinions, or the experimenter's own introspection. We formalize this problem using a multi-prior Bayesian approach that maps each source to a Bayesian model. These models are aggregated according to their associated posterior probabilities. We evaluate a broad of policy rules according to three criteria: whether the experimenter learns the parameters of the payoff distributions, the probability that the experimenter chooses the wrong treatment when deciding to stop the experiment, and the average rewards. We show that our framework exhibits several nice finite sample properties, including robustness to any source that is not externally valid

  5. Looming Large or Seeming Small? Attitudes Towards Losses in a Representative Sample
    Erschienen: July 2022
    Verlag:  National Bureau of Economic Research, Cambridge, Mass

    We measure individual-level loss aversion using three incentivized, representative surveys of the U.S. population (combined N=3,000). We find that around 50% of the U.S. population is loss tolerant, with many participants accepting... mehr

    We measure individual-level loss aversion using three incentivized, representative surveys of the U.S. population (combined N=3,000). We find that around 50% of the U.S. population is loss tolerant, with many participants accepting negative-expected-value gambles. This is counter to earlier findings--which mostly come from lab/student samples--and expert predictions that 70-90% of participants are loss averse. Consistent with the difference between our study and the prior literature, loss aversion is more prevalent in people with high cognitive ability. Loss-tolerant individuals are more likely to report recent gambling and to have experienced financial shocks. These results support the general hypothesis that individuals value gains and losses differently, although the tendency in a large proportion of the population to emphasize gains over losses is an overlooked behavioral phenomenon

    This study investigates how to use regression adjustment to reduce variance in experimental data. We show that the estimators recommended in the literature satisfy an orthogonality property with respect to the parameters of the adjustment. This observation greatly simplifies the derivation of the asymptotic variance of these estimators and allows us to solve for the efficient regression adjustment in a large class of adjustments. Our efficiency results generalize a number of previous results known in the literature. We then discuss how this efficient regression adjustment can be feasibly implemented. We show the practical relevance of our theory in two ways. First, we use our efficiency results to improve common practices currently employed in field experiments. Second, we show how our theory allows researchers to robustly incorporate machine learning techniques into their experimental estimators to minimize variance
