The employment effect in retail trade of California's 1988 minimum wage increase

In this paper, the authors study the outcome of an unusually clean natural experiment--California's large minimum wage increase of 1988. Two different approaches to evaluating the experiment result in the same conclusion: the textbook analysis of minimum wages holds true. In particular, the authors find that employment growth in California's low-wage retail trade industry was slowed by the minimum wage increase.

Predicted field-induced hexatic structure in an ionomer membrane

Coarse-grained molecular-dynamics simulations were used to study the morphological changes induced in a Nafion$^{\tiny \textregistered}$-like ionomer by the imposition of a strong electric field. We observe the formation of novel structures aligned along the direction of the applied field. The polar head groups of the ionomer side chains aggregate into clusters, which then form rod-like formations which assemble into a hexatic array aligned with the direction of the field. Occasionally these lines of sulfonates and protons form a helical structure. Upon removal of the electric field, the hexatic array of rod-like structures persists, and has a lower calculated free energy than the original isotropic morphology.Comment: 4 pages, 7 figure

LOGSIM programmer's manual

A programmer's manual is reported for a Logic Simulator (LOGSIM) computer program that is a large capacity event simulator with the capability to accurately simulate the effects of certain unknown states, rise and fall times, and floating nodes in large scale metal oxide semiconductor logic circuits. A detailed description of the software with flow charts is included within the report

An Analysis of Consolidation for the Farm Supply Sector

Changing farm numbers and a changing farm supply industry have prompted many regional cooperatives to consider consolidation of local branches as a means of remaining profitable. A behavioral model has been developed that would permit management of regional cooperatives to consider consolidation of product lines or complete branch closures. This model was used in an empirical analysis of a regional cooperative with an overinvestment in capital assets in its local branches. The results indicated that product line consolidation of major products would result in a greater savings than store closure.Agribusiness,

Neighborhood school characteristics: what signals quality to homebuyers?

Popular wisdom and economic research suggest that the quality of the neighborhood school should be an important determinant of housing values. Many researchers have found that housing values are higher where school spending or student test scores are higher. However, few economists consider these characteristics good indicators of school quality. Meanwhile, no one has examined whether the economists' notion of school quality-the school's marginal effect on students-is a school characteristic that matters to homebuyers. ; Using a model of new home purchases and historical data on homes in the Dallas Independent School District (DISD), Kathy Hayes and Lori Taylor demonstrate that property values do reflect the characteristics of the neighborhood school. They present evidence that property values reflect student test scores but not school expenditures. Interestingly, they also find that the relationship between test scores and property values arises from an underlying relationship between property values and the marginal effects of schools. Thus, their analysis suggests that homebuyers and economists share the same definition of school quality.Education ; Property tax
