From Libertarianism To Egalitarianism, Justin Schwartz

Justin Schwartz

A standard natural rights argument for libertarianism is based on the labor theory of property: the idea that I own my self and my labor, and so if I "mix" my own labor with something previously unowned or to which I have a have a right, I come to own the thing with which I have mixed by labor. This initially intuitively attractive idea is at the basis of the theories of property and the role of government of John Locke and Robert Nozick. Locke saw and Nozick agreed that fairness to others requires a proviso: that I leave "enough …

Nonparametric Event Study Tests, Arnold R. Cowan

Arnold R. Cowan

This paper provides the first documentation of the power and specification of the generalized sign test, which is based on the percentage of positive abnormal returns in an estimation period. In simulations using daily stock return data, the generalized sign test is well specified with both exchange listed and Nasdaq stocks. A rank test is more powerful under ideal conditions. However, the rank test is more sensitive to increases in the length of the event window, to increases in return variance and to thin trading. The generalized sign test is a viable alternative to the rank test under these conditions.
