Unobservable Transactions Price and the Measurement of a Supply and Demand Model for the American Steel Industry

This article develops a simultaneous supply-and-demand model of the American steel industry for the years 1920–1972. The analysis takes into account the differences between published (book) and actual transactions prices. The model also provides for the oligopolistic nature of the steel market and the possibility that price may deviate from marginal cost. The demand results are in conformance with theory and earlier empirical work, but on the supply side some problems exist with the input price parameters. A reason for this situation may be that the steel industry is a large user of some inputs, making the relationship between steel output and these factor prices simultaneous.     

Generalizing Clatworthy group divisible designs

In this paper a neat construction is provided for three new families of group divisible designs that generalize some designs from Clatworthy's table of the only 11 designs with two associate classes that have block size four, three groups, and replication numbers at most 10. In each case (namely, _λ1=4${\lambda }_1=4$ and _λ2=5${\lambda }_2=5$, _λ1=4${\lambda }_1=4$ and _λ2=2${\lambda }_2=2$, and _λ1=8${\lambda }_1=8$ and _λ2=4${\lambda }_2=4$), we have proved that the necessary conditions found are also sufficient for the existence of such GDD's with block size four and three groups, with one possible exception.     

Truth-in-sentencing, law enforcement, and inmate population growth

This paper presents the empirical estimation of an econometric model of the flow of prisoners into a state correctional system. Specifically, an econometric model was built to control for the number of parolees, the probability of admission to the state system, the size of the state population, the unemployment and poverty rates, the number of law enforcement officers within the state, and the state-wide “truth-in-sentencing” law, which requires convicts to serve at least 85% of their sentences. One primary result was that increases in the number of law enforcement officers has generated a decline in the growth rate of the prison population. This suggests that a “deterrent effect” is created when more police are placed on the beat. Furthermore, the results indicate that the truth-in-sentencing law has also slowed the rate of inmate population growth. This finding may reflect the growing trend for courts to hand down nontraditional sentences and to adjust prison sentences to reflect a constant “real time” of incarceration by crime.     

IDENTIFYING THE EFFECTS OF MONETARY POLICY SHOCKS ON EXCHANGE RATES USING HIGH FREQUENCY DATA

This paper proposes a new approach to identifying the effects of monetary policy shocks in an international vector autoregression. Using high‐frequency data on the prices of Fed Funds futures contracts, we measure the impact of the surprise component of the FOMC‐day Federal Reserve policy decision on financial variables, such as the exchange rate and the foreign interest rate. We show how this information can be used to achieve identification without having to make the usual strong assumption of a recursive ordering. (JEL: C32, E52, F30)     

Environmental resettlement and social dis/re-articulation in Inner Mongolia, China

The expanding use of resettlement as a tool for addressing environmental and poverty-related concerns in China calls for further research into its impacts on local populations. Our knowledge of the effects of such resettlement is very limited, particularly in relation to its social impacts. This paper examines the impoverishment risk of social disarticulation as it is experienced by resettlers in an Inner Mongolian environmental resettlement village—Wan Sheng village. We argue that social disarticulation as a risk of resettlement is by no means an inevitable downward spiral towards social oblivion and anomie. Resettlers, in this case at least, have recreated a living, functioning community that provides many aspects of support for its inhabitants. This is in spite of unfavourable construction and increased economic deprivation. It is the adaptive abilities of these resettlers that come to the fore in Wan Sheng, suggesting aspects of rearticulation and cohesion, and not simply disarticulation.

Dispersing the Serials Collection and Measuring Paper: Cooperative Storage Efforts and Legacy Journals Management in a University Library

This article discusses workflows involved with contributing print journal back runs to scanning and storage efforts. The purpose of these efforts was to alleviate space problems in a library by consolidating stacks that were formerly used to house runs of bound journals. This article contributes to the literature on serials withdrawal projects by demonstrating database designs for tracking contributions made to cooperative storage facilities as well as highlighting an innovative solution for tracking the required linear feet for housing bound print collections.     

Heterogeneity and selection in multistate population analysis

If one subgroup of individuals in a population has a higher death rate than the others, then over time the surviving population will include a larger share of those with the lower death rate. As a result, the aggregate average death rate for this increasingly more robust population will decline. This conclusion, however, can be drawn only for nonrecurrent events experienced by populations that do not exchange members with one another--that is, for noninteracting populations. Studies of changes in marital status, labor force activity, residential location, and active life, for example, all should focus on patterns of recurrent events among interacting populations (that is, multistate populations). Selection arising from heterogeneity will occur, but the consequences for average measures become unpredictable a priori. This paper explores such aspects of the selection effects of heterogeneity in multistate populations and illuminates some of their consequences for commonly used rates.     

The effects of maternal working conditions and mastery on child behavior problems: studying the intergenerational transmission of social control.

We assess the impact of maternal sense of mastery and maternal working conditions on maternal perceptions of children's behavior problems as a means to study the transmission of social control across generations. We use a sample of 521 employed mothers and their four-to six-year-old children from the National Longitudinal Survey's Youth Cohort in 1986. Regarding working conditions, we consider mother's hourly wage, work hours, and job content including involvement with things (vs. people), the requisite level of physical activity, and occupational complexity. We also consider maternal and child background and current family characteristics, including marital status, family size, and home environment. Maternal mastery was related to fewer reported behavior problems among children. Lower involvement with people and higher involvement with things, as well as low physical activity, were related significantly to higher levels of perceived problems. In addition, recent changes in maternal marital status, including maternal marriage or remarriage, increased reports of problems; stronger home environments had the opposite effect. We interpret these findings as suggesting how maternal experiences of control in the workplace and personal resources of control can influence the internalization of control in children.     

MINIMUM DISTANCE and INDUCED STATISTICS FOR TESTING INEQUALITIES

Minimum distance statistics for testing inequality restrictions on the mean vector of a multivariate normal population are considered and are shown to be equivalent to certain induced (or intersection) test statistics. Tests based on these statistics are shown to be admissible.
