Domestic innovations and technology imports play important roles in boosting relative demand for skilled labor force. These factors are in turn influenced by domestic R&D investments and international trade. Using a translog cost function, this paper studies the effect of technology imports and other factors including output level and physical capital stock on the shares of skilled labor force ...

practitioners needing estimates of a firm's equity cost of capital have long relied on the Capital Asset Pricing Model (CAPM). Recent evidence casts renewed doubt on the validity of the CAPM and beta. However, there is not much evidence to gauge the importance of the rejections of the CAPM in a practical decision-making context. This paper presents evidence on the sources of error in estimating...

Sensitivity analysis of capital investments can be effectively carried out by employing a metamodel approach and experimental designs. Although polynomial regression metamodels are popular and straightforward, they do not consider spatial relationships among the data. Dual kriging is an estimation technique that allows the incorporation of spatial correlation into the interpolation or estimatio...

Theory tells us that output, the capital stock and the user cost of capital are cointegrated. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. This has been used to justify the estimation of investment equations embodying a long-run relation between investment and output, rather than between the capital stoc...

the main goal of this paper is to estimate the level and distribution of human capital (hc) in tehran province, iran. in doing this we have first reviewed theoretical and empirical literature of human capital. and then we used do gum method for estimation of level and distribution of households’ human capital in tehran. the do gum method is based on three old methods of estimation. we used late...

This paper examines the implementation of the Integrated Activity-Based Costing and Economic Value Added System in the service sector. This system is intended for use by those service companies for which the traditional costing system is not adequate. Motivations for tracing overhead cost as well as capital cost, using the integrated system, are discussed. Resulting improvements in the reliabil...

Using a firm-level panel data set I assess whether dynamic models of investment provide an empirically fruitful framework for analyzing tax effects on changes in capital stock. In particular I estimate a one-step error correction model (ECM) complementing the usual estimation of a distributed lag model. A correction term accounts for non-random sample attrition, which has not been considered in...

In doing this we have first reviewed theoretical and empirical literature of human capital. And then we used Do gum Method for estimation of level and distribution of households’ human capital in Tehran. The Do gum Method is based on three old methods of estimation. We used late...

one of the most important and valuable goal of software development life cycle is software cost estimation or sce. during the recent years, sce has attracted the attention of researchers due to huge amount of software project requests. there have been proposed so many models using heuristic and meta-heuristic algorithms to do machine learning process for sce. cocomo81 is one of the most popular...
