We offer new evidence on the link between price points and price rigidity using two datasets. One is a large weekly transaction price dataset, covering 29 product categories over an eight-year period from a large U.S. supermarket chain. The other is from the Internet, and includes daily prices...

We study the link between price points and price rigidity, using two datasets containing over 100 million observations. We find that (i) 9 is the most frequently used price-ending for the penny, dime, dollar and ten-dollar digits, (ii) 9-ending prices are between 24%-73% less likely to change in...

The goal of technology transfer is to improve the livelihoods of rural households and communities. This goal is proposed to be achieved by pilot-testing a sustainable and integrated water and land management strategy in selected districts and provinces that will introduce or expand the use of...

Biomass thermochemical processes result in a common byproduct char. The char is also called biochar particularly when it is used as a soil amendment for soil health improvement. Effective utilization of biochar is critical for improving economic viability and environmental sustainability of...

Biomass gasification has the potential to produce renewable fuels, chemicals and power at large utility scale facilities. In these plants catalysts would likely be used to reform and clean the generated biomass syngas. Traditional catalysts are made from transition metals, while catalysts made...

Using the Nationwide Personal Transportation Study surveys of 1977 and 1983-84, this article demonstrates that there is no discernible relationship between city size class and trip lengths, times, and speeds, and that commuting speeds did not decline between 1977 and 1983. The most convincing...

This paper uses commuting times and distance data from the Nationwide Personal Transportation Studies of 1977 to 1983-4 to re-evaluate the spatial mismatch hypothesis. Neither minorities nor low-income workers have longer commutes. In fact, their commuting patterns are very similar to those of...

Climate change is likely to affect the agricultural production adversely and becomes more serious concern for developing countries because they do not have enough resources to mitigate the adverse effect of climate change. Statistics show that the amount of undernourished people is still...

Syngas, the main gasification product, is a well-known intermediate for making fuels, chemicals and power. The objective of this study was to develop and validate reaction kinetics-based gasification model using extents of major reactions in a CSTR (continuous stirred-tank reactor) to predict...
