We model a team in which the marginal productivity of a player increases with the effort of other players on the team. Because the effort of each player is not observable to any other player, the performance of the team is negatively affected by a free-rider problem and by a lack of effort coordination across players. In this context, a player who mistakenly overestimates her own marginal produ...

Co-management agreements, whereby community rules for the management of local floodplain lake fisheries are legalised and enforced by the government, have become common in the lower Amazon. Agreements are intended to limit exploitation, in particular by commercial boats, to raise stock abundance and fisheries productivity for the benefit of local subsistence-oriented fishers and for conservatio...

Early software effort estimation is a hallmark of successful software project management. Building a reliable effort estimation model usually requires historical data. Unfortunately, since the information available at early stages of software development is scarce, it is recommended to use software size metrics as key cost factor of effort estimation. Use Case Points (UCP) is a prominent size m...

Aim To test six hypotheses that could explain or mediate the positive correlation between human population density (HPD) and bird species richness while controlling for biased sampling effort. These hypotheses were labelled as follows: productivity (net primary productivity, NPP); inherent heterogeneity (diversity of vegetation types); anthropogenic heterogeneity (diversity of land uses); conse...

We model a team in which the marginal productivity of a player increases with the effort of other players on the team. Because the effort of each player is not observable to any other player, the performance of the team is negatively affected by a free-rider problem and by a lack of effort coordination across players. In this context, an overconfident player who overestimates her own marginal p...

Several finance and economics problems involve a team of agents in which the marginal productivity of any one agent increases with the effort of others on the team. Because the effort of each agent is not observable to any other agent, the performance of the team is negatively affected by a free-rider problem and by a lack of effort coordination across agents. In this context, we show that an a...

To estimate the corrective software maintenance effort, it is critical to know the factors that are most influential to the productivity of corrective maintenance activities. In this study, we analyzed activities and productivities of correcting 810 defects in one Norwegian software company and 688 defects in another Norwegian IT consulting company. We compared the profiles of defects that are ...

This research wants to examine how the management of creation works art made from organic waste (wood and marine biota) in Jaring Halus Village, North Sumatra. The method used this study was with an experimental model by utilizing as a for creating art. conducted Langkat, stages begin identifying internal external potentials. potential is location such wood biota like. Furthermore, community's ...
