Multi-Dimensional motivic pattern extraction founded on adaptive redundancy filtering
2005
Abstract We present a computational model for discovering repeated patterns in symbolic representations of monodic music. Patterns are discovered through an incremental adaptive identification along a multi-dimensional parametric space. The difficulties of pattern discovery mainly come from combinatorial redundancies, that our model is able to control efficiently. A specificity relation is defined between pattern descriptions, unifying suffix and inclusion relations and enabling a filtering of redundant descriptions. Combinatorial proliferation caused by successive repetitions of patterns is managed using cyclic patterns. The modelling of these redundancy control mechanisms enables an autom…
Intra-Party Heterogeneity in Policy Preferences and Its Effect on Issue Salience: Evidence from the Comparative Candidates Survey
2016
Quantitative research on the positions of political parties and party competition regularly invokes the assumption that parties are unitary actors with homogenous policy preferences. Drawing on Comparative Candidates Survey (CCS) data from 28 elections in 21 developed democracies, we show that candidates often hold quite heterogeneous issue positions and that the extent of this heterogeneity varies significantly across parties and, most interestingly, even within parties across different issue dimensions. In an effort to explore the implications of such intra-party heterogeneity for party strategy and competition, we argue that intra-party heterogeneity and issue salience go together, becau…
WITHIN-TEAM COMPETITION IN THE MINIMUM EFFORT COORDINATION GAME
2006
. We report the results of an experiment on a continuous version of the minimum effort coordination game. The introduction of within-team competition significantly increases effort levels relative to a baseline with no competition and increases coordination relative to a secure treatment where the pay-off-dominant equilibrium strategy weakly dominates all other actions. Nonetheless, within-team competition does not prevent subjects from polarizing both in the efficient and the inefficient equilibria.
The Relevance of Bargaining for the Licensing of a Cost-reducing Innovation*
2001
In the context of a Cournot duopoly, this paper studies the licensing of a cost-reducing innovation by means of three possible allocation mechanisms: auction, fixed fee, and direct negotiation. Once the use of an arbitrary reserve price (which is not credible) has been excluded, it is no longer true that auction always yields higher profit to the patentee than a fixed fee. However, the authors propose a direct negotiation mechanism which restores the patentee’s profit to the level of an auction with an arbitrary reserve price (which is unimplementable). Direct negotiation is superior to both an auction with a nonarbitrary reserve price and a fixed fee. From the social point of view, however…
NASH EQUILIBRIA IN A MODEL OF MULTIPRODUCT PRICE COMPETITION: AN ASSIGNMENT PROBLEM
2003
We study the market interaction of a finite number of single-product firms and a representative buyer, where the buyer consumes bundles of these goods. The buyers' value function determines their willingness to pay for subsets of goods. We show that subgame perfect Nash-equilibrium outcomes are solutions of the linear relaxation of an integer programming assignment problem and that they always exits. The (subgame perfect) Nash-equilibrium price set is characterized by the Pareto frontier of the associated dual problem's projection on the firms' price vectors. We identify the Nash-equilibrium prices for monotonic buyers' value functions and, more importantly, we show that some central soluti…
Retail pricing decisions and product category competitive structure
2010
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 output depends on the configuration of a supporting measurement model. The measurement model is a demand function that relates sales and prices within the category; optimal prices are those whose effects on demand and retail margins maximize the category's profitability. This investigation focuses particularly on the role of competitive structure, such that the authors consider two types of price competition asymmetries for demand forecasting: those depending on the bran…
The Role of Consulting Services in Promoting Competitive Culture
2019
Maintaining a normal competitive environment on the market is the core objective of the competition authorities. Policies and regulations applied in pursuit of this purpose have the role of identifying and eliminating situations of constraint on free competition. The developing market of Moldova is characterized by a low level of the competitive culture. Therefore, the business community have few knowledge and understanding of competition policies and regulations, relatively new in this market. In other cases, the lack of cooperation with competition authorities leads to erroneous information and ineffective decisions. In this context, the consultancy in the field of competition presents o…
Terrestrial carbon and intraspecific size-variation shape lake ecosystems
2007
Conceptual models of lake ecosystem structure and function have generally assumed that energy in pelagic systems is derived from in situ photosynthesis and that its use by higher trophic levels depends on the average properties of individuals in consumer populations.These views are challenged by evidence that allochthonous subsidies of organic carbon greatly influence energy mobilization and transfer and the trophic structure of pelagic food webs, and that size variation within consumer species has major ramifications for lake communitydynamics and structure. These discoveries represent conceptual shifts that have yet to be integrated into current views on lake ecosystems. Here, we assess k…
Attractiveness and Effectiveness of Competing Tourist Areas: A Study on Italian Provinces
2005
Tourism has become a wide-spread phenomenon in our age and a focal point of economic policy of many regions competing for the favours of tourists. Consequently, competitiveness of tourist destinations has received increasing interest in economic research with a view to the identification of the user attractiveness of a tourist area. The present paper is inspired by the conceptual competitiveness model developed by Crouch and Ritchie and presents an attempt to assess the relative attractiveness of tourist destinations on the basis of aggregate tourist strength of competing destinations. The main novelty of the present work is formed by the micro-based foundation of tourism attractiveness of …
Is tourism firm competitiveness driven by different internal or external specific factors?: New empirical evidence from Spain
2015
Abstract The quest to understand the multilevel antecedents of competitiveness has led to a separation of approaches. On one side of the question are the environment theories that analyze the structural characteristics of the general and competitive environment. On the other side are the Resource Based View and its extensions that highlight firm-specific resources and capabilities as the main basis of firms' competitiveness. However, in recent years the nature of competition and shifting economic conditions have given rise to new theoretical approaches that complement the assumptions underlying both environmental and firm theories. Specifically, this study contributes by examining the regio…
