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...

This paper quantifies the effects of increasing maximum unemployment insurance (UI) duration during recessions on drop in correlation between output and labour productivity U.S. since early 1980s – so-called puzzle. Using a general equilibrium search matching model with stochastic UI duration, heterogeneous match quality, variable intensity on-the-job search, I demonstrate that can explain over...

Enterprise integration technologies are a key contributor to improving time-to-market, cost, and design quality by a factor, which is the goal of the DARPA Rapid Prototyping of Application-Specific Signal Processors (RASSP) program [1]. The Lockheed Martin Advanced Technology Laboratories (ATL) RASSP team developed a productivity improvement model, shown in Figure 1, that indicates the relative...

The NBER business cycle dating process has traditionally mixed together the fundamental component of business cycles, changes in real output, with changes of employment. This paper makes the case that these long and variable lags disqualify for business cycle dating all the components of labor market behavior, including aggregate hours of work and payroll employment. By definition real GDP is e...

How long would it take for forests to recover their original productivity following continuous intensive management if they are left untouched? This issue was explored using the model FORECAST, calibrated and validated for coastal Douglas-fir stands on Vancouver Island (western Canada). Three types of forest management (production of timber, pulp, and biomass) were simulated, being different in...

In the 7th edition of PMBOK Tailoring process is legitimized as an essential ally in project management, since it makes several adjustments throughout project's life cycle to provide best possible environment achieve deliverables and value added organization. a principle further highlights unique nature each need carry out this continuously. Based on case study, beginning management functions s...

abstract comparison of food prices in different periods, indicates fluctuations and continually upward trend. any change in agricultural sector variables, as main food supplier, will affect food price. productivity shocks and production gap are examples of such variables. in this paper ,hodrick prescott and kalman filters are used as generators of productivity shocks and production gap series. ...
