BACKGROUND Program effectiveness is influenced by the degree and quality of implementation, thus requiring careful examination of delivery processes and how the program is or is not being implemented as intended. Implementation fidelity is defined by adherence to intervention design, exposure or dose, quality of delivery, and participant responsiveness. As part of the process evaluation (PE) of...

We use a Barro–Becker model of endogenous fertility, in which parents are subject to idiosyncratic shocks that are private information (either to labor productivity or taste for leisure), to study the efficient degree of consumption inequality in the long run. The planner uses the trade-off between family size and future consumption and leisure, to provide incentives for workers to reveal their...

This study was undertaken to assess the socio-economic impact of producing export oriented agricultural crops on the livelihoods of the farmers, in eastern Ethiopia. A random sample of 305 farmers was studied. Comparisons were made between producers and non-producers using the Ztest and regression analysis. It was found that producers of export oriented crops are better off than the non-produce...

OBJECTIVE The objective of this study was to examine the predictive relationships between employee health risk factors (HRFs) and workers' compensation (WC) claim occurrence and costs. METHODS Logistic regression and generalised linear models were used to estimate the predictive association between HRFs and claim occurrence and cost among a cohort of 16 926 employees from 314 large, medium an...

What is the impact on human capital investment when a worker’s ability and investments are observed by the labour market only when the worker invests in self-promoting activities? When ...rms pay spot market wages, high ability workers overinvest in selfpromotion. There is no employment contract that attains full e¢ciency. Constrained e¢ciency is attained when employment bonds are feasible. The...

This paper assesses whether there is a systematic di¤erence between the accident rates of ...xed-term and permanent contract workers that is not just the result of a compositional e¤ect. A pure contractual e¤ect leading to a higher accident rate might exist because the short duration of the temporary contract reduces the incentives to invest in speci...c human capital or because e¤ort is higher...

Nike and other brand companies have long been the target of widespread criticism for outsourcing their manufacturing production to contract factories with dismal working conditions. Despite the overwhelming amount of public interest, there exists no theory for studying this topic. The current paper fills this gap. In the model, the most productive firms in the North make high profits and outsou...

We model personnel policies in public agencies, examining how wages and promotion standards can partially offset a fundamental contracting problem: the inability of public sector workers to contract on performance, and the inability of political masters to contract on forbearance from meddling. Despite the dual contracting problem, properly constructed personnel policies can encourage intrinsic...

Economic Integration and Labor Market Institutions: Worker Mobility, Earnings Risk, and Contract Structure This paper investigates the effects of labor market integration, in the form of worker mobility, in a model with long-term labor contracts that lead to wage rigidities and unemployment. Reflecting the interdependence of regional labor markets, we develop a general-equilibrium framework whe...
