The productivity of the most attractive terms of applications in various fields, particularly management. In this regard, human resources productivity plays a key role in any organization.  This study aimed to investigate the relationship between work ethics and productivity of human resources management, time management .Time do research hypotheses using questionnaire distributed among m...

Wages and Productivity Growth in a Dynamic Monopoly* This Paper studies the intertemporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm’s rate of productivity growth approaches the rate of wage growth and eventually the firm reaches a steady state where its unit labour cost remain...

This paper provides a comparison of two learning curve models that are used to quantify the productivity increase experienced as a result of process improvements and new technology adoption. Evaluating productivity increase is essential for estimating the cycle time and effort required to complete a software project. At SSERL, we have been using software process modeling and simulation to predi...

We introduce the fatigue disutility model. Set in continuous-time, the model captures in a precise way the notion that fatigue accumulates with effort, decays with rest, and produces an increase in marginal instant disutility. The model is meant to be prescriptive, although it rationalizes several anomalies observed in time preference. Under very general conditions the most efficient temporal p...

We study a firm in which the marginal productivity of agents’ effort increases with the effort of others. We show that the presence of an agent who overestimates his marginal productivity may make all agents better off, including the biased agent himself. This Pareto improvement is obtained even when compensation contracts are set endogenously to maximize firm value. We show that the presence o...

This paper can be interpreted in one of two ways. Some readers can take it as a small, quirky contribution aimed to clarify the literature on optimal income taxation. Others can take it as a broader effort to challenge that entire literature. In particular, our results can be seen as raising a fundamental question about the framework for optimal taxation which remains a centerpiece of modern pu...

The study sets out to assess the link between land leasing behavior and productivity differentials between male and female headed households. A non-cooperative game model with double-moral hazard allowed us to show that landlord’s tenure insecurity leads to sub-optimal level of effort on tenant’s part. The landlord’s enforcement ability is also shown to increase the optimal level of effort. The...

A major challenge for small-scale fisheries management is high spatial variability in the demography and life history characteristics of target species. Implementation of local management actions that can reduce overfishing and maximize yields requires quantifying ecological heterogeneity at small spatial scales and is therefore limited by available resources and data. Collaborative fisheries r...
