In this paper we show that generative models are competitive with and sometimes superior to discriminative models, when both kinds of models are allowed to learn structures that are optimal for discrimination. In particular, we compare Bayesian Networks and Conditional loglinear models on two NLP tasks. We observe that when the structure of the generative model encodes very strong independence ...

a r t i c l e i n f o Keywords: Retail pricing decision model Demand forecasting Market share models Category management Competitive structure Store-level scanner data This study addresses the use of demand forecasting techniques by retailers to support their decision making. Specifically, the authors propose a pricing decision support model for retailers to estimate optimal prices, whose outpu...

In most professional sports, playing field structure is kept neutral so that scoring imbalances may be attributed to differences in team skill. It thus remains unknown what impact environmental heterogeneities can have on scoring dynamics or competitive advantages. Applying a novel generative model of scoring dynamics to roughly 10 million team competitions drawn from an online game, we quantif...

in this paper, monopolistic behavior of opec, as the largest and most stable international organization between jan. 1973 to sep. 2008, is studied. for this purpose, fundamentals of game theory is used as a basis to come-up with a criterion to make a distinction between two market structures based on mutual dependency of institutions. then using such criterion, a regressive model based on expla...

There are three cases that we wish to study. Each involves the equilibrium adjustment in a competitive market to changes in exogenous constraints. Number one is the effect of a change in an input price; two is the effect of an input restriction; and three is the effect of an output quota. An example of the first case is the minimum wage. When the government increases the minimum wage, we want t...

This paper analyzes the internal characteristics of organizational structure which have an influence on the development of hybrid competitive strategies and their link to firm performance. The study examines a sample of large Spanish firms belonging to different sectors by means of the Partial Least Squares (PLS) technique, using formative dimensions for competitive strategy and organizational ...

We study a general equilibrium model with production where financial markets are incomplete. At a competitive equilibrium firms take their production and financial decisions so as to maximize their value. We show that shareholders unanimously support value maximization. Furthermore, competitive equilibria are constrained Pareto efficient. Finally the Modigliani-Miller theorem typically does not...

This paper makes two contributions to the carbon-sequestration literature. The first is the development of a theoretical framework within which sequestration and permit trading may be analyzed jointly in the context of a competitive fringe model. The second is a numerical analysis of the model. We find that when the cost-structure changes lead to progressively less separation in costs between t...
