ACADEMIC EMPLOYMENT

**Professor**:

Recent research projects include the development of software based analysis techniques designed to assess the elements of an inverse Jacobian matrix based upon a nonparametric specification of the Jacobian matrix. The computer programs apply mathematical results derived separately on the stability and invertibility of matrices as related to characteristics of their signed directed graphs. Applications of the results have been found in computer model quality control and the evaluation of econometric models.

NON-ACADEMIC EMPLOYMENT

**OPTIMA Consulting Services, 1983 - present.** Provides advice and
software development on the use of mathematical and statistical techniques in
the development of information products to support management decision making
and analysis. A particular emphasis is the integration of information
requirements and specific management needs through the use of interactive
software tailored to user specifications. Applications include mathematical
processing and graphical displays of components from the solution sets of large
forecasting models, the integration and analysis of interregional data
describing alternative technologies for commercial building heating and
cooling, models of options pricing, and the risk/return performance of
financial futures contracts.

**Decision Analysis Corporation, 1985 - 1998.** Provides advice and
technical services in the development and use of mathematical and statistical
models of energy production, distribution, and consumption. Specific projects
include: the estimation of a reduced form version of the Oil Market Module, a
model of petroleum product refining and distribution, based upon "pseudo
data" generated by the Oil Trade Model, a large programming based model of
international petroleum product production and distribution; an assessment of
the scope of and problems with measures of the environmental and other external
impacts of energy production and consumption; participated in the design of
(the National Energy Modeling System's) components for residential and
commercial energy consumption; and conducted an assessment of Federal
Government intervention in energy markets and its consequences.

** ANSTEC, 1991 - 1994.** Developed the analytical and software
basis for finding the signs of comparative statics multipliers based upon the
signs of the elements of a mathematical model's Jacobean matrix. Developed an
application of the software for the Oil Market Simulation (OMS), a model of
international oil pricing and the Oil and Gas Supply Model.

**Senior Manager**:

**Director, Office of Analysis Oversight and Access**:

**Director, Office of Coal, Nuclear and Electric Power Analysis**: GS -
16/3, 1975 - 1979. Responsible for all data analysis and modeling in the
assigned energy types. Designed and directed the use of systems that forecast
energy supply availability up to twenty years into the future under a variety
of geological, economic, and regulatory assumptions. Applications included the
study of the economic consequences of: a curtailment of nuclear based supply
development, the imposition of more stringent environmental standards on energy
use, and the general issue of energy price regulation.

**Chief, Short-Term Energy Forecasting Division**: GS - 15/5, 1974 -
1975. Designed automated systems and directed the preparation of forecasts of
short-term energy supply and demand. A particular emphasis was that of
determining the consequences of supply disruptions due to such as import
embargoes, coal miners' strikes, and surges in energy demand such as that
related to severely cold weather.

**Program Manager**: The Resource Management Corporation, 1968 - 1974.
Designed and directed contract research projects to evaluate a variety of
government based programs and systems. Techniques utilized included
multivariate parametric and non-parametric statistics, optimization theory,
directed graphs, Markov Processes, queuing theory, and general cost/benefit
analysis. Specific projects included: Evaluation of manpower training programs;
development of rigorous models for long range planning; analysis of
transportation systems' cost/benefits; mathematical simulation of the Navy
Supply System; evaluation of alternative land combat system designs; and
analysis of determinants of reserve component accession rates.

Development of computer simulations of electricity generation and dispatch at a state level of geographic detail to enable an analysis of the consequences of the deregulation of markets for electricity , Decision Analysis Corporation Of Virginia.

Development of a computer simulation, BINSIM, of commercial building heating
and cooling based upon alternative technologies and standards for
building-shell thermal characteristics. Data were assembled for over one
hundred heating/cooling technologies and building thermal shell characteristics
for thirty-two climate typologies (BINS). Economic and behavioral assumptions
were utilized in forecasting technology selection for new commercial buildings
in the time frame 1996-2000. Based on these projections the efficiency of
alternative regulatory formulae was assessed and presented in: *Analysis of
ASHRAE Standard 90.1-1989R Building Envelope Requirements* (written with
Jason Glazer), Gas Research Institute, October 1997.

Development of graf98, a PC-based graphic interface utilized by the Energy
Information Administration (EIA), U.S. Department of Energy in conjunction with
the National Energy Modeling System (NEMS). NEMS generates large, 2.4MB, solution
sets describing projections of domestic and international production and
consumption of energy products through the year 2020. Solutions are prepared
under alternative assumptions concerning economic performance, the
characteristics of international markets for oil, technological change, and
government regulatory policies. Currently, NEMS is being used to assess the
economic and other impacts of reducing carbon emissions from the combustion of
fossil-based energy as agreed in

Software and Users Guide for ECONSIM, computer-based simulations of economic
activity developed in support of Economics 3544. This program is installed in

Developed Sim_Inverse and Qual_Check, compiled as a Windows applications using Microsoft’s Visual Studio 6. These applications conduct a Monte Carlo simulation of the distribution of reduced form sign patterns based upon assumed structural sign patterns to determine the information content of a structural hypothesis and the feasibility of estimated reduced forms to correspond to proposed structural arrays, 2007-2011. The software supported the findings in the two publications noted below:

“Structural Models,
Information and Inherited Restrictions,” with Andrew Buck, *Economic Modelling*, 28, 2011, pp. 2820-2831..

“Structural Sign Patterns
and Reduced Form Restrictions, “ with Andrew Buck, *Economic Modelling*, 29, 2012, pp. 462-470.

Developed Big_Sim, compiled as a Windows application using Microsoft’s
Visual Studio 6. This application complements the two applications cited above.
These two applications are limited to an analysis of reduced form sign patterns
limited to less than 30 bits of information, i.e., thirty signs. Big_Sim can
assess very much larger arrays. It can also isolate particular entries in the
reduced form for analysis. This feature enables a further analysis of the
underlying system of inequalities to be parsed to identify the inconsistences
associated with a falsified reduced form. The software was developed and tested
in the summer of 2013. This software is intended for use in the development of
the paper: *Qualitative Comparative
Statics*, now being written with coauthor Andrew Buck.
