Problem statement: Estimation models in software engineering are used to predict some important attributes of future entities such as development effort, software reliability and programmers productivity. Among these models, those estimating software effort have motivated considerable research in recent years. Approach: In this study we discussed an available work on the effort estimation metho...

Wage dispersion is generated in a sequential search environment through heterogeneity in firm productivity along with an individual wage-effort tradeoff. For a given degree of TFP dispersion, the framework can generate any amount of wage dispersion. Calibrated to generate realistic gains from trade, it is able to generate the kind of wage dispersion observed in data. JEL codes: E24, J64

1 This study reports the analysis of data collected during the execution of a reverse engineering process in a real environment. Essentially, the analysis assessed productivity aspects. The experience showed the need for automatic tools which can be adapted to the context the process is performed in and the possibility of anchoring the effort required for the reverse engineering to the desired ...

Software development involves a number of interrelated factors which affect development effort and productivity. Since many of these relationships are not well understood, accurate estimation of so&are development time and effort is a dificult problem. Most estimation models in use or proposed in the literature are based on regression techniques. This paper examines the potential of two artijci...

How does effort respond to the perceived relationship between effort and rewards? The answer is ambiguous since leisure and rewards can be either substitutes or complements. To answer this question, I conduct a two-part field experiment with a widely used online learning platform. For one group of students, I measure the causal relationship between effort and rewards. Then, for a second group o...

This study separates and compares sorting and incentive effects and analyses their contingencies in a real-effort laboratory experiment. Depending on the treatment, subjects have a choice between a piece rate, a budget-based and a fixed pay, or have no choice but are assigned to a compensation scheme. The results suggest that sorting effects have a greater impact on productivity than incentive ...

In this paper, we construct a simple model based on heterogeneity in workers’ productivity and homogeneity in their working schedules. This simple model can generate unemployment, even if wages adjust instantaneously, firms are perfectly competitive, and firms can perfectly observe workers’ productivity and effort. In our model, it is optimal for low-skilled workers to be unemployed because, on...

Agricultural and other physically demanding sectors are important sources of growth in developing countries but prevalent diseases such as malaria adversely impact the productivity, labor supply, and occupational choice of workers in these sectors by reducing physical capacity. This study identifies the impact of malaria on worker earnings, labor supply, and daily productivity by randomizing th...

This paper evaluates the impact of varying implementation of electronic lab order entry management (eLAB) system strategies on hospitals’ productivity in the short run. Using the American Hospital Association's Annual Surveys for 2005–2008, we developed hospital productivity measures to assess facilities’ relative performances upon implementing eLAB systems. The results indicate that different ...

An exploratory study was conducted (a) to examine whether experieticed software managers could generate accurate estimates of effort required for proposed software projects and (b) to document the strategies they bring to bear in their estimations. Five experienced software project managers served as expert subjects for the study. Each manager was first asked to sort a set of 37 commonly-used e...
