The purpose of this study is to investigate the existence of economies of scale and other economic parameters influencing the rate of return of the domestic solid waste collection process. To this end, the case of the Attica region in Greece, which includes equal amounts of urban and rural areas, is considered. The investigating approach is performed via the transcendental logarithmic cost func...

This paper uses the adaptive Lasso estimator to determine variables important for economic growth. The adaptive Lasso estimator is a computationally very efficient procedure that simultaneously performs model selection and parameter estimation. The computational cost of this method is negligibly small compared with standard approaches in the growth regressions literature. We apply this method f...

In this paper, we present an alternative strategy for estimation of DSGE models when data is available at di¤erent time intervals. Our method is based on a data augmentation technique within Bayesian estimation of structural models and allows us to jointly use data at di¤erent frequencies. The bene…ts achieved via this methodology will be twofold, resolution of time aggregation bias and identi…...

One of the most important aspects of software project management is the estimation of cost and time required for running information system. Therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. Software cost estimation refers to the process of development requirement prediction of software system. Various kinds of effort estimation patter...

In empirical tests guided by recent theory (e.g., Hughes, Liu and Liu 2007; and Lambert, Leuz and Verrecchia 2012), we examine the joint effects of information asymmetry and information precision on the cost of capital and how these effects vary based on the amount and quality of available information and the level of market competition. Consistent with theory, we find that average information ...

BACKGROUND Typically, little consideration is given to the allocation of indirect costs (overheads and capital) to hospital services, compared to the allocation of direct costs. Weighted service allocation is believed to provide the most accurate indirect cost estimation, but the method is time consuming. OBJECTIVE To determine whether hourly rate, inpatient day, and marginal mark-up allocati...

The Health Care Financing Administration (HCFA) has proposed incorporating hospital capital payments into the Medicare prospective payment system. HCFA's proposal includes an adjustment to capital payments for geographic differences in capital costs, derived from the prospective payment system area hospital wage index. Alternatively, the geographic adjustment could be based on an area construct...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...
