A novel incentive-based demand response model for Cournot competition in electricity markets
This paper presents an analysis of competition between generators when
incentive-based demand response is employed in an electricity market. Thermal
and hydropower generation are considered in the model. A smooth inverse demand
function is designed using a sigmoid and two linear functions for modeling the
consumer preferences under incentive-based demand response program. Generators
compete to sell energy bilaterally to consumers and system operator provides
transmission and arbitrage services. The profit of each agent is posed as an
optimization problem, then the competition result is found by solving
simultaneously Karush-Kuhn-Tucker conditions for all generators. A Nash-Cournot
equilibrium is found when the system operates normally and at peak demand times
when DR is required. Under this model, results show that DR diminishes the
energy consumption at peak periods, shifts the power requirement to off-peak
times and improves the net consumer surplus due to incentives received for
participating in DR program. However, the generators decrease their profit due
to the reduction of traded energy and market prices

The Future of Retail Operations
Retailing consists of all the activities associated with the selling of goods to the final consumer. In this article, we review the research on retail operations published in Manufacturing & Service Operations Research (M&SOM) since 1999. We then discuss the current retail landscape and the new research directions it offers, in which M&SOM can play a prominent role
EXPLORING SUPPLY DYNAMICS IN COMPETITIVE MARKETS
Understanding the ebb and flow of competitive markets is essential for students pursuing a variety of undergraduate degrees. The objective of this study is to introduce users to interactions that occur in the supply side of competitive markets using a dynamic simulation model with curriculum materials.Marketing,
A new comparative approach to macroeconomic modeling and policy analysis
In the aftermath of the global financial crisis, the state of macroeconomic modeling and the use of macroeconomic models in policy analysis has come under heavy criticism. Macroeconomists in academia and policy institutions have been blamed for relying too much on a particular class of macroeconomic models. This paper proposes a comparative approach to macroeconomic policy analysis that is open to competing modeling paradigms. Macroeconomic model comparison projects have helped produce some very influential insights such as the Taylor rule. However, they have been infrequent and costly, because they require the input of many teams of researchers and multiple meetings to obtain a limited set of comparative findings. This paper provides a new approach that enables individual researchers to conduct model comparisons easily, frequently, at low cost and on a large scale. Using this approach a model archive is built that includes many well-known empirically estimated models that may be used for quantitative analysis of monetary and fiscal stabilization policies. A computational platform is created that allows straightforward comparisons of models’ implications. Its application is illustrated by comparing different monetary and fiscal policies across selected models. Researchers can easily include new models in the data base and compare the effects of novel extensions to established benchmarks thereby fostering a comparative instead of insular approach to model development
Dairy Deregulation and Low-Input Dairy Production: A Bioeconomic Evaluation
Deregulation of the Australian dairy industry could affect the utilization of resources by milk producers and the profitability of dairy production. In this study we examine the feed mix that dairy producers use, both pastures and supplements, under partial and total deregulation. We are particularly interested in the interaction of pasture utilization and farm profitability. The results of this research demonstrate that profitable low-input dairying is constrained by the most limiting resource, feed supplied by pasture, and that the interactions between economic and biological processes are critical to farm profitability
