With a novel experimental design we investigate whether risk perception, return expectations, and investment propensity are influenced by the scale of the vertical axis in charts. We explore this for two presentation formats, namely return charts and price charts, where we depict low- and...

Guttman (1947) developed a scaling method in which the items measuring an attribute can be ordered according to the … strength of the attribute. The Guttman scaling model assumes that every member of the population belongs to a scale type and … contingency tables, pi-star can be applied to latent class models, including scaling models for dichotomous data. This study …

This paper evaluates the causal impacts of an early childhood home visiting program for which treatment is randomly assigned. We estimate multivariate latent skill profiles for individual children and compare treatments and controls. We identify average treatment effects of skills on performance...

This paper uses random assignment to estimate the causal impacts on child skills of a widely emulated early childhood home visiting program. We show the feasibility of replicating it at scale. We estimate vectors of latent skills for individual children and compare treatments and controls. The...
