Knowledge that Transforms

Most empirical work in economics has considered only a narrow set of measures as meaningful and useful to characterize individual behavior, a restriction justified by the difficulties in collecting a wider set. However, this approach often forces the use of strong assumptions to estimate the parameters that inform individual behavior and identify causal links. In this paper, we argue that a more flexible and broader approach to measurement could be extremely useful and allow the estimation of richer and more realistic models that rest on weaker identifying assumptions. We argue that the design of measurement tools should interact with, and depend on, the models economists use. Measurement is not a substitute for rigorous theory, it is an important complement to it, and should be developed in parallel to it. We illustrate these arguments with a model of parental behavior estimated on pilot data that combines conventional measures with novel ones.

Society, and the Society of Labor Economists.For more than three decades, Janet has pioneered research on the role of education, family background, social transfer programs, access to health care, and environmental factors in shaping the health and well-being of children and their outcomes as adults.She was a prime mover in making the study of the fetal period and child development an essential concern of labor economics.This pioneering work had a major influence on other fields, including the economics of education, health economics, public economics, and environmental economics.In the early 1990s, Janet started a research agenda on the effectiveness of early childhood
