The objective of this paper is to introduce models to determine an effective, feasible, and cost-efficient strategy for Saudi Arabia’s water supply system to meet its projected demand in 2025. This paper uses cost minimizing and production maximizing approaches to build the models. The water management system is divided into three processes–desalination, distribution, and wastewater treatment. ...

Abstract Achieving economic growth, as one of the essential purposes in each country, needs appropriate tracing of government as one of the important and effective sections in that economy. Nowadays, unlike the 80s, economists concentrate on objectives such as explanation of the relationship between size of the government and economic growth and delineation of optimum size of the government w...

The attack levels of plant pest organisms (PPO) highly influence the productivity paddy rice farming. With increasing human awareness dangers using pesticides, especially for environment and health, PPO control prioritizes preventive by applying principles integrative management (IPM), which application healthy crop cultivation, routine observation, utilization natural enemies farmers as IPM ex...

In this study, we used the probit model to find out determinants of access formal credit and then applied Cobb–Douglas production function examine impact on sugarcane productivity. To elicit choice consequence productivity, divided farmers into two groups: borrowers nonborrowers. A total sample comprised 120 growers from Badin District—rich in production—Sindh, Pakistan. For analysis purposes, ...

The published article proposes a mathematical model of the dynamics product output by manufacturing enterprise, whose labor resources are being replaced digital technologies and robotics. development is based on application dynamic two-factor production function enterprise. structure this includes variable from zero to one dimensionless logistic digitalization two Cobb-Douglas functions. first ...

The set of Cobb-Douglas production functions is usually fitted by first linearizing the models through logarithmic transformation and then applying method of least squares. However, this procedure is valid only when the underlying assumption of multiplicative error-terms is justified. Unfortunately, this assumption is rarely satisfied in practice and accordingly, the results obtained are of dou...

We investigate whether better population health may impact economic performance through improvements in technical efficiency in agricultural production. Using district-level data from India, we employ a random-coefficients approach to estimate a Cobb-Douglas production function, computing overall and input-specific technical efficiencies for each district. We then model health (district infant ...
