We use administrative records on the incomes of more than 40 million children and their parents to describe three features of intergenerational mobility in the United States. First, we characterize the joint distribution of parent and child income at the national level. The conditional expectation of child income given parent income is linear in percentile(More)
The neurotrophin receptor TrkA plays critical roles in the nervous system by recruiting signaling molecules that activate pathways required for the growth and survival of neurons. Here, we report APPL1 as a TrkA-associated protein. APPL1 and TrkA co-immunoprecipitated in sympathetic neurons. We have identified two routes through which this association can(More)

There is a growing public perception that intergenerational income mobility—a child's chance of moving up in the income distribution relative to her parents—is declining in the United States. We present new evidence on trends in intergenerational mobility using administrative earnings records for children born between 1971 and 1993. For the 1971–1986 birth(More)
In this paper a experiment is presented in which two simulated robots evolved a form of communication to allow one of the robots to complete the task of finding a light placed in the world. The robots are constrained so that one has inputs about the world, seeing robot, and the other, blind robot, has no sensors besides an input from the seeing robot. The(More)
Project managers love him, recent software engineering graduatesbow to him, and he inspires code warriors deep in the developmenttrenches to wonder if a technology time warp may have passed themby. How can it be that no one else has ever proposed softwaredevelopment with the simplicity, innovation, and automation beingtrumpeted by Architect Tom? His ideas(More)
