In this paper, we discuss the application of maps of linked markers to identify genes of economic importance to the livestock industries and summarize significant results to date. We describe our approach to identify genes associated with beef carcass merit in the ‘Angleton project. ” We consider the potential benefits and limitations of marker-assisted selection and discuss issues of additivit...

We rst provide an empirical study of the energy-saving technological progress on the ENERDATA database. Energy intensity is shown to decrease over the period 1971-1999 in OECD countries, indicating a signi cant energy-saving technical progress trend. We also show via semi-parametric partially linear estimations that: (i) this trend is positively correlated with the investment rate, and (ii) the...

This paper presents a detailed accounting of the sources of African-American economic progress in the labor market over the twentieth century. We examine the received literature and demonstrate the sensitivity of conclusions stated in it to choices of samples used to measure wages and to specifications of earnings functions. We present a quantitative assessment of the contributions of migration...

This entry examines the economic determinants of child maltreatment. We first discuss potential mechanisms through which economic factors, including income, employment, aggregate economic conditions, and welfare receipt, might have causal effects on the rates of child abuse and neglect. We then outline the main challenges faced by researchers attempting to identify these causal effects, emphasi...

Q uantitative theory uses simple, abstract economic models together with a small amount of economic data to highlight major economic mechanisms. To illustrate the methods of quantitative theory, we review studies of the production function by Paul Douglas, Robert Solow, and Edward Prescott. Consideration of these studies takes an important research area from its earliest days through contempora...

Aggregate monotonicity of cooperative solutions is widely accepted as a desirable property, and examples where certain solution concepts (such as the nucleolus) violate this property are scarce and have no economic interpretation. We provide an example of a simple fourplayer game that points out at a class of economic contexts where aggregate monotonicity is not appealing.
