Past projections of wind-powered electricity by several organizations including Energy Information Administration have been too conservative in the past. We generate alternative projections for China, the U.S., India, Canada, Japan and South Korea and compare them against the projections made by...

By far, the most popular type of corruption measurements used is Corruption Perception Index published annually since 1995 by Transparency International. We examine whether country differences of the Corruption Perception Index existing in 2003 has narrowed by 2015 and if so, how fast. We deploy...

Many countries in the world have been experiencing widely varying rates of change in their carbon intensity of economic output. Dynamic trend of carbon intensity in this research is measured by the progress ratio from experience curve involving 127 countries during the period of 1980 to 2011....

Over the past three decades, urban congestion has become more costly in terms of time, money and fuel. Congestion has generated, for the 101 large U.S urban centers, 4.8 billion hours of travel delay in 2011, up from 1.1 billion hours in 1982. We examine the scaling relationship between the...

Kinked experience curve model is presented as a major alternative to classical experience curve model. Whenever a sudden shift in the historical pattern of data occurs, the use of kinked model may yield a more accurate and reliable future projection. The purpose of this paper is to present an...

The Energy Information Administration (EIA) of the U.S. Department of Energy has projected net electricity generation through 2040 for ten selected countries and the world. These ten countries including China and the U.S. are projected to produce 70% of the world electricity generation. Some of...

Through analyzing the scaling relationship between the population size and the death count of four major disease categories in the United States from 1999 to 2010, we discover that there is a super-linear relationship in terms of the total counties, regardless of the four disease categories. We...

Countries’ energy intensity levels are known to converge at both the world and the regional levels. We test convergence in energy intensity for the world using a more recent and larger data set: a 152-country sample during the period of 1980-2010. Furthermore, we use income, population and...

Both the Federal government and individual state governments in America establish long-term road fatality targets to plan and evaluate the effectiveness of their respective safety programs. The purpose of this paper is to develop customized fatality projection model and to project future...
