The Effectiveness of Reinstatement as a Public Policy Remedy: The Kohler Case

This article is concerned with two aspects of the NLRB reinstatement remedy as applied in the famous Kohler case: (1) how effective the remedy was, particularly in terms of the number of employees who returned to Kohler under its protection, and (2) what factors, in order of significance, affected a worker\u27s decision to return. The authors find the remedy was effective, since about 40 percent of those workers who received reinstatement offers accepted them. Regression and discriminant analyses of the variables affecting the decision to return confirm the thinking of labor market economists that the most disadvantaged worker (lower paid, older, less educated, less skilled, married, with children and with a nonworking wife) was most likely to return to a Kohler job. Recommendations are offered for improving the efficacy of the reinstatement remedy, with emphasis on adding a penalty cost to its back-pay feature

The Outcome of Impasse Procedures in New York Schools Under the Taylor Law

The effectiveness of New York’s Taylor Law, and of the Public Employment Relations Board established under it, may be measured in a number of ways. One is to see whether it does, in fact, eliminate strikes of public employees. Another is to compare the results of mediation and fact-finding under the Board’s auspices with settlements arrived at without intervention of PERB. The authors, who are engaged in a broad study of the latter kind, present some of their findings as they relate to the public school system during 1969 and 1970

The Influence of Collective Bargaining on Teachers’ Salaries in New York State

This study tests a model of teacher salary determination with data describing several aspects of all school districts in New York state, outside of New York City. The authors find that collective bargaining is not significant in explaining variations in 1968 teacher salaries among all school districts, but bargaining did have a significant effect among small districts and on the rate of salary change from 1967 to 1968. On the whole, however, the authors conclude that the results of this and other studies show that bargaining has had a surprisingly minor effect on teacher salaries

Household Income and Vehicle Fuel Economy in California

This white paper presents the findings from an analysis of the fiscal implications for vehicle owners of changing from the current statewide fuel tax to a “road user charge” (RUC) based on vehicle-miles traveled (VMT). Since 1923, California’s motor vehicle fuel tax has provided revenue used to plan, construct, and maintain the state’s publicly funded transportation systems. Over time, improvements in vehicle fuel efficiency and the effects of inflation have reduced both the revenue from the fuel tax and its purchasing power. Thus, there is growing interest among policy makers for replacing the state’s per-gallon fuel tax with an RUC based on VMT. This study analyzes the 2010-2011California Household Travel Survey (CHTS) to identify the potential effects this policy change would be likely to have on households across the state. The analysis found that while daily household fuel consumption and VMT both appear to increase with household income, urban and rural households show roughly the same amount of fuel consumption and VMT. No statistically significant difference in cost was found between the two programs in any income group. This suggests that an RUC designed to collect the same amount of revenues statewide as the current fuel tax would not place a significant financial burden on California households

Economic Development and the Timing and Components of Population Growth

This paper examines the relationship between population growth and economic growth in developing countries from 1965 to 1985. Our results indicate that developing countries were able to shift their labor force from low-productivity agriculture to the higher-productivity industry and service sectors, and to increase productivity within those sectors, despite the rapid growth of their populations. We also find that at given rates of population growth, income growth is related to the time path of population growth and that population growth due to high birth and death rates is associated with slower income growth than population growth due to relatively low birth and death rates. Hence, the timing and components of population growth are important elements in the process of economic development.

Metabolic network percolation quantifies biosynthetic capabilities across the human oral microbiome

The biosynthetic capabilities of microbes underlie their growth and interactions, playing a prominent role in microbial community structure. For large, diverse microbial communities, prediction of these capabilities is limited by uncertainty about metabolic functions and environmental conditions. To address this challenge, we propose a probabilistic method, inspired by percolation theory, to computationally quantify how robustly a genome-derived metabolic network produces a given set of metabolites under an ensemble of variable environments. We used this method to compile an atlas of predicted biosynthetic capabilities for 97 metabolites across 456 human oral microbes. This atlas captures taxonomically-related trends in biomass composition, and makes it possible to estimate inter-microbial metabolic distances that correlate with microbial co-occurrences. We also found a distinct cluster of fastidious/uncultivated taxa, including several Saccharibacteria (TM7) species, characterized by their abundant metabolic deficiencies. By embracing uncertainty, our approach can be broadly applied to understanding metabolic interactions in complex microbial ecosystems.T32GM008764 - NIGMS NIH HHS; T32 GM008764 - NIGMS NIH HHS; R01 DE024468 - NIDCR NIH HHS; R01 GM121950 - NIGMS NIH HHS; DE-SC0012627 - Biological and Environmental Research; RGP0020/2016 - Human Frontier Science Program; NSFOCE-BSF 1635070 - National Science Foundation; HR0011-15-C-0091 - Defense Advanced Research Projects Agency; R37DE016937 - NIDCR NIH HHS; R37 DE016937 - NIDCR NIH HHS; R01GM121950 - NIGMS NIH HHS; R01DE024468 - NIDCR NIH HHS; 1457695 - National Science FoundationPublished versio
