We empirically implement a dynamic structural model of labor supply and welfare program participation for agents with potentially time-inconsistent preferences. Using panel data on the choices of single women with children from the NLSY 1979, we provide estimates of the degree of time-inconsistency, and of its influence on the welfare take-up decision.

The standard gravity model predicts that trade flows increase in proportion to importer and exporter total income, regardless of how income is divided into income per capita and population. Bilateral trade data, however, show that trade grows strongly with income per capita and is largely unresponsive to population. I develop a general equilibrium,(More)
An individual is defined as working in a calendar year if annual hours are at least 780. Wages, converted to1983 dollars using the GDP deflator, are for those age 16 to 64. Imputed wages are dropped, top-coded wages are set at twice the top-coded level and wages below 2 dollars are dropped. The self-employed are not included. 3 Only accepted wages, wages(More)
BACKGROUND The development and homeostasis of multicellular organisms depends on sheets of epithelial cells. Bazooka (Baz; PAR-3) localizes to the apical circumference of epithelial cells and is a key hub in the protein interaction network regulating epithelial structure. We sought to identify additional proteins that function with Baz to regulate(More)
Nanoparticle-based platforms have drawn considerable attention for their potential effect on oncology and other biomedical fields. However, their in vivo application is challenged by insufficient accumulation and retention within tumors due to limited specificity to the target, and an inability to traverse biological barriers. Here, we present a nanoprobe(More)
This study sought to increase current understanding of the neuropsychological basis of poor reading ability by using fMRI to examine brain activation during a visual sentence comprehension task among good and poor readers in the third (n = 32) and fifth (n = 35) grades. Reading ability, age, and the combination of both factors made unique contributions to(More)
—A maximum-likelihood (ML) coarse symbol synchronization algorithm for OFDM systems in multipath channels is derived. Several simplifying assumptions reduce the rather impractical ML algorithm to more practical forms of minimum mean-squared-error and maximum correlation algorithms. All of the derived algorithms exploit the cyclic prefix and thus do not(More)
This paper develops and estimates a dynamic general equilibrium overlapping generations model of career decisions. The model is fit to data on life cycle employment, schooling and occupation decisions, and on life cycle labor earnings, within and between cohorts observed in the US between 1968 and 1993. Based on the estimates of the model, the impact of(More)
