Water conveyance, return flows and technology choice

Street Storm Water Conveyance Capacity

The street hydraulic capacity to convey storm water is dictated by the street gutter geometry and hydraulic characteristics. With the consideration of traffic safety, the street hydraulic conveyance capacity is also subject to a reduction defined by the water velocity and flow depth in the street gutter. In this study, the street hydraulic equation is re-arranged to demonstrate that the water v...

Quarterly Accruals or Cash Flows? Return Analysis

This study explores the incremental roles of accruals and net operating cash flows in generating abnormal returns using quarterly and rolling four-quarter data for the entire population of firms, as well as specific industries. Our results show that quarterly net operating cash flow (OCF) is a stronger signal about subsequent quarter’s returns than accruals, and that this result is also true fo...

The Economics of Water-Conserving Technology Adoption in Tunisia: An Empirical Estimation of Farmer Technology Choice*

Introduction Economic theory tells us that increases in the relative prices of natural resources should cause farmers to switch to techniques that use fewer farming resources. The adoption of resource-conserving technology is one possible response that can lead toward a more environmentally sustainable outcome. Do farmers respond to changes in natural resource prices and quality by adopting ava...
