Broughton, John | Size of the bursa of fabricius in relation to gonad size and age in laysan and black-footed albatrosses | Age determination can be difficult for birds that undergo little or no plumage change during life. This is the case for Laysan and Black-footed Albatrosses (Diomedea immutabilis and D. nigripes). The juvenile plumage for both these North Pacific albatrosses is completely grown by about five to six m... | Birds; Species; Development | 1994 |

Hawkes, Kristen | On life history evolution (a comment on Chisholm) | Chisholm (CA 34:I-24) is right that the theory, models, and data of evolutionary biology apply to questions asked by social scientists. Work in life-history theory (Stearns 1992, Roff 1992, Charnov 1993) has especially provocative implications for the understanding of human development (see review i... | | 1994-01-01 |

Maloney, Thomas N. | Wage compression and wage inequality between black and white males in the United States, 1940-1960 | The gap between the mean wages of black men and white men in the United States narrowed substantially between 1940 and 1950. There was, however, almost no change in this wage gap between 1950 and 1960. Some of this discontinuity in the path of black progress can be explained by general changes in th... | Salaries; Race; Compensation | 1994-06 |

Rogers, Alan R. | Evolution of time preference by natural selection | This paper entertains the hypothesis that human time preferences are in evolutionary equilibrium (i.e. that no mutation changing time preferences could be favored by natural selection). This hypothesis implies that the marginal rate of substitution (MRS) holding Darwinian fitness constant must equal... | Capitalism; Econometric models; Equilibrium | 1994-06 |
