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…
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…
Quality and competition between public and private firms
2017
We study a multistage, quality-then-price game between a public firm and a private firm. The market consists of a set of consumers who have different quality valuations. The public firm aims to maximize social surplus, whereas the private firm maximizes profit. In the first stage, both firms simultaneously choose qualities. In the second stage, both firms simultaneously choose prices. Consumers’ quality valuations are drawn from a general distribution. Each firm's unit production cost is an increasing and convex function of quality. There are multiple equilibria. In some, the public firm chooses a low quality, and the private firm chooses a high quality. In others, the opposite is true. We …
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 …

Intraguild interactions between two egg parasitoids exploring host patches
2010
Intraguild interactions between two egg parasitoids, Trissolcus basalis (Hymenoptera: Scelionidae) and Ooencyrtus telenomicida (Hymenoptera: Encyrtidae), exploring egg masses of the Southern Green Stink Bug (SGSB) Nezara viridula (Heteroptera: Pentatomidae), were investigated in laboratory conditions by single, simultaneous and sequential host attack experiments. Mortality of N. viridula eggs was higher in simultaneous and sequential releases compared to single species releases. In simultaneous host exploitations, T. basalis females displayed an aggressive behavior against O. telenomicida females. The outcome of multiparasitism showed that interspecific larval competition was dominated by O…
Spacing and Organizing: Process Approaches to the Study of Organizational Space
2018
In the past several decades, the research on space in management studies has moved from being an implicit idea to becoming an important generative force in organizational theory. Through this turn, space no longer surfaces as a stable container in which organizing occurs, rather it is a process for enacting organizing. Even with the growth of studies on organizational space, only a modicum of work exists that aims to distill and theorize the notion of space as organizing. This paper sets forth a typology of process studies on organizational space linked to two dimensions and five approaches for conceiving of space as organizing. In offering this typology, it not only provides an overview of…
Análisis de las acciones técnicas de los judokas cadetes participantes en el campeonato de España.
2009
El entrenamiento del judoka dada su amplia estructura técnica, su dimensión táctica, su estructuración por categorías de peso y la incertidumbre creada por el adversario, muestra diversos y complejos aspectos a considerar, que deben ser analizados en situación real de competición. Desde esta perspectiva, la presente investigación tiene como objetivos identificar las características técnicas y tácticas de los judokas cadetes masculinos de nivel nacional, en cada una de las categorías de peso, a través del análisis de las acciones técnicas más utilizadas por los participantes en el campeonato de España de judo cadete. La muestra está formada por 128 judokas cadetes masculinos, de los que se a…
