During the 1980s wage differentials between younger and older

facts is…

We examine why some individuals survive as entrepreneurs and others do not. In
addition. we analyze the growth of entrepreneurial enterprises, conditional on surviving. Our
focus is on the role of access to capital--to what extent do liquidity constraints increase…

Problems encountered in the description of ion-induced compositional changes in non-monatomic solids, on the basis of the binary collision approach (BCA), are reported. The ingredients of a collisional model responsible for eventual ambiguity of computer simulation results are pointed out.…

In this study we examine the experience of a single large hospital with an
informal pre-litigation “complaint” process that resolves some cases outside of the legal
system. The empirical results are generally consistent with an information structure where
patients are…

Throughout the late 1970s and the early 1980s, over 50% of all first-time first-year college
students started in a junior college. Despite such a large role in higher education, we know
relatively little about how well they serve their role…

By applying Gaussian optics we propose a new matrix formula model for intraocular lens (IOL) calculation that yields not only IOL optical power for a particular eye but also an evaluation of the bending factor of different IOL optical designs.…
