Documenting Decline in U.S. Economic Mobility
(American Association for the Advancement of Science (AAAS), 2017-04-24)Economists and other social scientists have long studied intergenerational income mobility, but consistent data linking adult incomes of children and their parents at similar ages over many generations have been unavailable, ... -
Does a two-element muscle model offer advantages when estimating ankle plantar flexor forces during human cycling?
(Elsevier BV, 2018-02)Traditional Hill-type muscle models, parameterized using high-quality experimental data, are often “too weak” to reproduce the joint torques generated by healthy adults during rapid, high force tasks. This study investigated ... -
Does Cognitive Behavioral Therapy for Youth Anxiety Outperform Usual Care in Community Clinics? An Initial Effectiveness Test
(Elsevier BV, 2010)Objective: Most tests of cognitive behavioral therapy (CBT) for youth anxiety disorders have shown beneficial effects, but these have been efficacy trials with recruited youths treated by researcher-employed therapists. ... -
Does Competition Destroy Ethical Behavior?
(American Economic Association, 2004)Explanations of unethical behavior often neglect the role of competition, as opposed to greed, in assuring its spread. Using the examples of child labor, corruption, "excessive" executive pay, corporate earnings manipulation, ... -
