Why did newly freed slaves and their descendants wait a half century before migrating in large numbers to the superior economic opportunities in the North? Census lifetime migration data on both movers and stayers are examined intertemporally for both whites and blacks. Regression analysis...

The paper lacks an abstract but provides additional insights into why blacks remained in the South for so long following the Emancipation Proclamation leading to the abolition of slavery in the United States

Various disciplines have produced models to explain and predict migration. A model is presented providing a taxonomy through which interdisciplinary insights can be synthesized. The imperfect information view emphasizes the role of wage differentials as representing arbitragible real utility...

In the 1970's, the percentage of high school graduates completing RN training increased with little change in the rate of return to training. During the 1980's this percentage declined, despite large increases in the rate of return. The national data employed here examine long-run trends (with...

There is no abstract for this paper, but what it establishes is that a first-best policy intervention would set optimal mandatory deposits on automobiles. Moreover, a littering fine for abandonment of automobiles is seen to be second-best, either with or without a mandatory deposit, leading to...

A model of the optimal speed limit is developed which explicitly recognizes the role of average speed, speed variance, and the level of enforcement. An unusual result emerges, namely that a higher speed limit may be optimal when reducing the variance in highway speeds reduces accident externalities

The authors demonstrate that most textbooks are ambiguous at best in their treatment of cross-price and income elasticity of demand. There is also no discussion of what initiates a price increase in discussions of substitutes and complements in the textbooks examined. The authors offer a remedy...
