Economic theory states that “free market” competition naturally achieves lower prices—thereby increasing efficiency and benefiting society. This is the first paper in the literature to use means testing to statistically analyze electricity prices, from 1970-2011, for states that...

The electric power industry is moving away from a regulated utility model, toward a deregulated marketbased model—thereby intending to improve system efficiency by reducing generation costs and customer prices, while at the same time improving capital expenditures and service reliability....

The goal of this paper is to test if the promised U.S. electrical system high reliability standards are being maintained, once states deregulate their electric utilities. This research is the first in the literature to combine states that offer retail choice, by deregulating their electric...

The electric power industry is moving away from a regulated utility model, toward a deregulated market-based model - thereby intending to improve system efficiency by reducing generation costs and customer prices, while at the same time improving capital expenditures and service reliability....

This new stock market trading rule uses three steps to remove random unsystemic risk from stock price data to smooth volatility. Proving empirically that a technical analysis relative maxima and minima trading rule for an S&P 500 Index portfolio substantially beats a naïve buy-and-hold policy,...

Two heuristics based on branch and bound (B&B) are developed to solve closed-loop material requirements planning (MRP) lot-sizing problems that have general product structures and variable costs. A “look ahead method'’(LAM) heuristic allows for variable production/purchasing costs and uses a...
