Motivating Employee Owners in ESOP Firms: Human Resource Policies and Company Performance

What enables some employee ownership firms to overcome the free rider problem andmotivate employees to improve performance? This study analyzes the role of humanresource policies in the performance of employee ownership companies, using employeesurvey data from 14 companies and a national sample of employee-owners. Between-firmcomparisons of 11 ESOP firms show that an index of human resource policies, nominallycontrolled by management, is positively related to employee reports of co-workerperformance and other good workplace outcomes (including perceptions of fairness, goodsupervision, and worker input and influence). Within-firm comparisons in three ESOP firms,and exploratory results from a national survey, show that employee-owners who participatein employee involvement committees are more likely to exert peer pressure on shirking coworkers.We conclude that an understanding of how and when employee ownership workssuccessfully requires a three-pronged analysis of: 1) the incentives that ownership gives; 2)the participative mechanisms available to workers to act on those incentives; and 3) thecorporate culture which battles against tendencies to free ride.human resources, industrial relations, employee ownership

Creating a Bigger Pie? The Effects of Employee Ownership, Profit Sharing, and Stock Options on Workplace Performance

This paper uses data from NBER surveys of over 40,000 employees in hundreds of facilities in 14 firms and from employees on the 2002 and 2006 General Social Surveys to explore how shared compensation affects turnover, absenteeism, loyalty, worker effort, and other outcomes affecting workplace performance. The empirical analysis shows that shared capitalism has beneficial effects on all outcomes save for absenteeism and that it has its strongest effects on turnover, loyalty, and worker effort when it is combined with: a) high-performance work policies (employee involvement, training, and job security), b) low levels of supervision, and c) fixed wages that are at or above market level. Most workers report that cash incentives, stock options, ESOP stock, and ESPP participation motivate them to work harder. The interaction of the effects of shared capitalism with other corporate policies suggests that the various shared capitalist and other policies may operate through a latent variable, "corporate culture".

Pollinator-flower interactions in gardens during the covid 19 pandemic lockdown of 2020

During the main COVID-19 global pandemic lockdown period of 2020 an impromptu set of pollination ecologists came together via social media and personal contacts to carry out standardised surveys of the flower visits and plants in gardens. The surveys involved 67 rural, suburban and urban gardens, of various sizes, ranging from 61.18° North in Norway to 37.96° South in Australia, resulting in a data set of 25,174 rows, with each row being a unique interaction record for that date/site/plant species, and comprising almost 47,000 visits to flowers, as well as records of flowers that were not visited by pollinators, for over 1,000 species and varieties belonging to more than 460 genera and 96 plant families. The more than 650 species of flower visitors belong to 12 orders of invertebrates and four of vertebrates. In this first publication from the project, we present a brief description of the data and make it freely available for any researchers to use in the future, the only restriction being that they cite this paper in the first instance. The data generated from these global surveys will provide scientific evidence to help us understand the role that private gardens (in urban, rural and suburban areas) can play in conserving insect pollinators and identify management actions to enhance their potential

Quantitative 18F-AV1451 Brain Tau PET Imaging in Cognitively Normal Older Adults, Mild Cognitive Impairment, and Alzheimer's Disease Patients

Recent developments of tau Positron Emission Tomography (PET) allows assessment of regional neurofibrillary tangles (NFTs) deposition in human brain. Among the tau PET molecular probes, 18F-AV1451 is characterized by high selectivity for pathologic tau aggregates over amyloid plaques, limited non-specific binding in white and gray matter, and confined off-target binding. The objectives of the study are (1) to quantitatively characterize regional brain tau deposition measured by 18F-AV1451 PET in cognitively normal older adults (CN), mild cognitive impairment (MCI), and AD participants; (2) to evaluate the correlations between cerebrospinal fluid (CSF) biomarkers or Mini-Mental State Examination (MMSE) and 18F-AV1451 PET standardized uptake value ratio (SUVR); and (3) to evaluate the partial volume effects on 18F-AV1451 brain uptake.Methods: The study included total 115 participants (CN = 49, MCI = 58, and AD = 8) from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Preprocessed 18F-AV1451 PET images, structural MRIs, and demographic and clinical assessments were downloaded from the ADNI database. A reblurred Van Cittertiteration method was used for voxelwise partial volume correction (PVC) on PET images. Structural MRIs were used for PET spatial normalization and region of interest (ROI) definition in standard space. The parametric images of 18F-AV1451 SUVR relative to cerebellum were calculated. The ROI SUVR measurements from PVC and non-PVC SUVR images were compared. The correlation between ROI 18F-AV1451 SUVR and the measurements of MMSE, CSF total tau (t-tau), and phosphorylated tau (p-tau) were also assessed.Results:18F-AV1451 prominently specific binding was found in the amygdala, entorhinal cortex, parahippocampus, fusiform, posterior cingulate, temporal, parietal, and frontal brain regions. Most regional SUVRs showed significantly higher uptake of 18F-AV1451 in AD than MCI and CN participants. SUVRs of small regions like amygdala, entorhinal cortex and parahippocampus were statistically improved by PVC in all groups (p < 0.01). Although there was an increasing tendency of 18F-AV-1451 SUVRs in MCI group compared with CN group, no significant difference of 18F-AV1451 deposition was found between CN and MCI brains with or without PVC (p > 0.05). Declined MMSE score was observed with increasing 18F-AV1451 binding in amygdala, entorhinal cortex, parahippocampus, and fusiform. CSF p-tau was positively correlated with 18F-AV1451 deposition. PVC improved the results of 18F-AV-1451 tau deposition and correlation studies in small brain regions.Conclusion: The typical deposition of 18F-AV1451 tau PET imaging in AD brain was found in amygdala, entorhinal cortex, fusiform and parahippocampus, and these regions were strongly associated with cognitive impairment and CSF biomarkers. Although more deposition was observed in MCI group, the 18F-AV-1451 PET imaging could not differentiate the MCI patients from CN population. More tau deposition related to decreased MMSE score and increased level of CSF p-tau, especially in ROIs of amygdala, entorhinal cortex and parahippocampus. PVC did improve the results of tau deposition and correlation studies in small brain regions and suggest to be routinely used in 18F-AV1451 tau PET quantification

2011) Consumption Inequality and Intrahousehold Allocations The

Abstract The consumption literature uses adult equivalence scales to measure individual level inequality. This practice imposes the assumption that there is no within household inequality. In this paper, we show that ignoring consumption inequality within households produces misleading estimates of inequality along two dimensions. To illustrate this point we use a collective model of household behavior to estimate consumption inequality in the UK from 1968 to 2001. First, the use of adult equivalence scales underestimates the initial level of cross sectional consumption inequality by 50 percent, as large differences in the earnings of husbands and wives translate into large differences in consumption allocations within households. Second, we estimate the rise in between household inequality has been accompanied by an offsetting reduction in within household inequality. Our findings also indicate that increases in marital sorting on wages and hours worked can simultaneously explain two thirds of the decline in within household inequality and between a quarter and one-half of the rise in between household inequality for one and two adult households.
