Marvell ([double dagger]) Keywords: K42; C5 Abstract: Abstract Although control variables are the reason for multiple regression, surprising little attention is given to the process of locating and selecting the controls. If important controls are omitted, estimates can be biased and inconsistent whereas using too many controls can reduce efficiency and mask effects. We advocate a much broader search for controls than is customary, at least in the crime literature, and then the use of the general-to-specific methodology to select the relevant controls. We illustrate this procedure using a fixed effects panel data design evaluating the effect of legalized abortion on crime.

15. Forecasting marginal costs of a multiple-output production technology

Abstract

A comparison of two different forecasting components, the Oil Marketing Module (OMM) and the Oil Trade Model (OTM), found that OMM forecasts oil supply prices with the same effectiveness as OTM in a far shorter time. Data obtained via OTM was used to estimate OMM's performance. Both programs were run on a 386/25 PC: OTM occupied 1.4M and solved in 10 minutes; OMM occupied 74K and solved in 3-4 seconds. Results of the tests are given.

Abstract

This article explores the influence of age structure on the number of inmates in state prisons and the number of court commitments to prisons. Several studies had incorrectly predicted that the aging of the baby boom cohort would cause prison populations to decline in the 1990s, and this research endeavors to determine the reason for this failure. Using a multiple time series design with state data over approximately twenty years, the analysis regresses prison variables on the proportion of population in high-imprisonment-rate age groups (eighteen to twenty-four, twenty-five to thirty-four, and thirty-five to forty-four). A major finding is that age structure is, in fact, related to court commitments and prison populations. This is also true for both males and females when studied separately. The failure of predictions that prison commitments and population would decline is caused by other factors that have stronger impacts than age-structure trends. These trends will place downward pressures on future prison populations, but the trends cannot be used to forecast prison populations. [C] 1997 Elsevier Science Ltd
