Towards And Integrated Agricultural Greenhouse Gas Model: Greenhouse Gases From Agriculture Simulation Model (Greenagsim), Jerome R.F. Dumortier, Dermot J. Hayes May 2009

Towards And Integrated Agricultural Greenhouse Gas Model: Greenhouse Gases From Agriculture Simulation Model (Greenagsim), Jerome R.F. Dumortier, Dermot J. Hayes

Economics Presentations, Posters and Proceedings

The present model aims to quantify greenhouse gas (GHG) emissions from changes in agricultural activity on a global scale. It is based on the FAPRI Agricultural Outlook Model, which is used to project changes in agricultural activity in approximately 35 countries and regions covering 13 crops (grains, oilseeds, rice, cotton, sugar) and two major livestock categories (cattle and swine). The FAPRI model is used to project the impact of policy changes on agriculture, and then the GreenAgSiM model is used to calculate the impact of these changes on GHG emissions. The GreenAgSiM model can be used to evaluate the GHG ...


Capacity Withholding In Restructured Wholesale Power Markets: An Agent-Based Test Bed Study, Hongyan Li, Leigh Tesfatsion Jan 2009

Capacity Withholding In Restructured Wholesale Power Markets: An Agent-Based Test Bed Study, Hongyan Li, Leigh Tesfatsion

Economics Presentations, Posters and Proceedings

This study uses a dynamic 5-bus test case implemented via the AMES Wholesale Power Market Test Bed to investigate strategic capacity withholding by generation companies (GenCos) in restructured wholesale power markets under systematically varied demand conditions. The strategic behaviors of the GenCos are simulated by means of a stochastic reinforcement learning algorithm motivated by human-subject laboratory experiments. The learning GenCos attempt to improve their earnings over time by strategic selection of their reported supply offers. This strategic selection can involve both physical capacity withholding (reporting of lower-than-true maximum operating capacity) and economic capacity withholding (reporting of higher-than-true marginal costs). We ...


Scenario Generation For Price Forecasting In Restructured Wholesale Power Markets, Qun Zhou, Leigh Tesfatsion, Chen-Ching Liu Jan 2009

Scenario Generation For Price Forecasting In Restructured Wholesale Power Markets, Qun Zhou, Leigh Tesfatsion, Chen-Ching Liu

Economics Presentations, Posters and Proceedings

Abstract: In current restructured wholesale power markets, the short length of time series for prices makes it difficult to use empirical price data to test existing price forecasting tools and to develop new price forecasting tools. This study therefore proposes a two-stage approach for generating simulated price scenarios based on the available price data. The first stage consists of an Autoregressive Moving Average (ARMA) model for determining scenarios of cleared demands and scheduled generator outages (D&O), and a moment-matching method for reducing the number of D&O scenarios to a practical scale. In the second stage, polynomials are fitted ...


The Rise Of Obesity In Transition: Theory And Empirical Evidence From Russia, Sonya K. Huffman, Marian Rizov Jan 2009

The Rise Of Obesity In Transition: Theory And Empirical Evidence From Russia, Sonya K. Huffman, Marian Rizov

Economics Presentations, Posters and Proceedings

Since the early 1990s series of political and economic reforms have been implemented in transition economies. As a result, the population experienced dramatic changes in lifestyle and a significant decline in life expectancy. The adverse effects of transition were most severe in the Former Soviet Union. Several studies examine the reasons for the mortality crisis in Russia and other former Soviet republics (Brainerd and Cutler, 2005; Shkolnikov et al., 2004). Greater alcohol consumption and increased stress from the transition to a market economy had dramatically affected the lifestyle and diet of the population, and led to higher mortality in Russia ...


Locational Marginal Pricing Basics For Restructured Wholesale Power Markets, Haifeng Liu, Leigh Tesfatsion, A.A. Chowdhury Jan 2009

Locational Marginal Pricing Basics For Restructured Wholesale Power Markets, Haifeng Liu, Leigh Tesfatsion, A.A. Chowdhury

Economics Presentations, Posters and Proceedings

Abstract: Although Locational Marginal Pricing (LMP) plays an important role in many restructured wholesale power markets, the detailed derivation of LMPs as actually used in industry practice is not readily available. This lack of transparency greatly hinders the efforts of researchers to evaluate the performance of these markets. In this paper, different AC and DC optimal power flow (OPF) models are presented to help understand the derivation of LMPs. As a byproduct of this analysis, the paper provides a rigorous explanation of the basic LMP and LMP-decomposition formulas (neglecting real power losses) presented without derivation in the business practice manuals ...
