When contracting is not possible, a preference for fair exchange can generate efficient exchange, fully exhausting the potential gains from trade — or no exchange at all, leaving all gains from trade unexploited. A profit-maximizing firm offers a wage to a fair-minded worker, who then chooses how much effort to exert. The Rotten Firm theorem says: if the worker cares sufficiently about fairness...

We introduce and consider the problem of effectively organizing a population of workers of varying abilities. We assume that arriving tasks for the workforce are homogeneous, and that each is characterized by an unknown and onedimensional difficulty value x ∈ [0, 1]. Each worker i is characterized by their ability wi ∈ [0, 1], and can solve the task if and only if x ≤ wi. If a worker is unable ...

Foreign Ownership, Employment and Wages in Brazil: Evidence from Acquisitions, Divestments and Job Movers How much do developing countries benefit from foreign investment? We contribute to this question by comparing the employment and wage practices of foreign and domestic firms in Brazil, using detailed matched firm-worker panel data. In order to control for unobserved worker differences, we e...

Job Durations with Worker and Firm Specific Effects: MCMC Estimation with Longitudinal Employer-Employee Data We study job durations using a multivariate hazard model allowing for worker-specific and firm-specific unobserved determinants. The latter are captured by unobserved heterogeneity terms or random effects, one at the firm level and another at the worker level. This enables us to decompo...

AIM To examine health worker-client interactions during care planning to understand processes that foster client empowerment and disempowerment. BACKGROUND It is unclear how health worker-client exchanges and information sharing through chronic condition care planning currently operate in primary health care. Moreover, it is unclear how control in these exchanges either enhances collaborative...

Complex social structure in eusocial insects can involve worker morphological and behavioural differentiation. Neuroanatomical variation may underscore worker division of labour, but the regulatory mechanisms of size-based task specialization in polymorphic species are unknown. The Australian weaver ant, Oecophylla smaragdina, exhibits worker polyphenism: larger major workers aggressively defen...

We investigated the extent to which workers reproduce in a dependent-lineage population of the monogynous harvester ant Pogonomyrmex barbatus. Dependent-lineage populations contain two interbreeding, yet genetically distinct mitochondrial lineages, each associated with specific alleles at nuclear loci. Workers develop from matings between lineages, and queens develop from matings within lineage...

he many burdens of government include those attributable to taxation, monetary policy, regulations, and restrictions on civil liberties. This paper is specific to the economic burden of taxation, without in any way minimizing the other types of burdens. The economic burden of taxation is a function of three conditions: the level of the average tax rate, the relation of the marginal tax rate to ...

Significant increases in herd size in the dairy industry have resulted in hired labor providing primary care and management of the cows guided by protocols. Worker training programs have been instituted to provide workers with an understanding of the hows and whys of the protocols they are asked to follow. The ultimate goal of training is to have competent workers carrying out best management p...

The 1972 Survey of Disabled and Nondisabled Adults found that more than 1 million severely disabled persons aged 20-64 were receiving payments under Federal-State public assistance programs. To determine the reasons why most of these individuals did not qualify for disabled-worker benefits under the social security program, their characteristics were compared with those of the approximately 1.5...
