Opaque Distribution Channels for Competing Service Providers: Posted Price vs. Name-Your-Own-Price Mechanisms
2014
Opaque selling has been widely adopted by service providers in the travel industry to sell off leftover capacity under stochastic demand. We consider a two-stage model to study the impact of different selling mechanisms, posted price (PP) versus name-your-own-price (NYOP), of an opaque reseller on competing service providers who face forward-looking customers. We find that in this environment, providers prefer that the opaque reseller uses a posted price instead of a bidding model. This is because the ability to set retail prices is critical for extracting surplus from customers who wait to purchase from the reseller. Such surplus extraction enables providers to set high prices for advance…
Sytuacja mieszkaniowa gospodarstw domowych na wsi w Polsce w 2016 r. w świetle badań budżetów gospodarstw domowych = Housing status of rural areas’ h…
2017
Artykuł dotyczy problematyki nierówności poziomu zaspokojenia potrzeby mieszkaniowej na wsi w Polsce, jako podstawowej determinanty poziomu życia. Celem zaprezentowanych w nim badań jest identyfikacja zróżnicowania sytuacji mieszkaniowej oraz subiektywnych ocen gospodarstw domowych na wsi i porównanie ich z wybranymi obiektywnymi charakterystykami sytuacji materialnej tych podmiotów. Za reprezentatywne wskaźniki sytuacji mieszkaniowej gospodarstwa domowego przyjęto liczbę osób przypadających na 1 izbę w mieszkaniu, średnią liczbę m2 przypadających na 1 osobę w mieszkaniu czy fakt zamieszkiwania w samodzielnym mieszkaniu. Badano również wybrane charakterystyki jakości mieszkań. Przeprowadzon…
Poverty Reduction: The Paradox of the Endogenous Poverty Line
2007
When evaluating poverty, the relative poverty line may be considered as a percentage of the median income or it may be a percentage of the average income. It is proved that, with a poverty line relative to the median income, reducing poverty may become less costly in proportion to the total income as poverty increases (measured by the Sen, the Sen-Shorrocks-Thon or the Foster-Greer-Thorbecke poverty indexes) by passing from a Lorenz concentration curve to another curve associated with more poverty. This is obviously a paradox, although a largely overlooked one. However, it is shown that the paradox vanishes if the poverty line is relative to the average income. The demonstration is both exp…
The paradox of endogenous poverty line in the poverty indices
2007
february 23-25, 2007; When measuring poverty, the poverty line is considered to be relatively determined as a percentage of the median income or as a percentage of the average income so as to allow international comparisons. The poverty line relative to the median income may be described as endogenous in contrast with the poverty line relative to the average income which may be described as exogenous because it is independent of the normalized distribution of incomes. As the existing literature is focused on the properties of the indices but not on the respective interest of the endogenous and exogenous poverty lines, this paper compares the two definitions of the relative poverty. The Rela…
A Power Law Behavior in the Incentivized Italian Photovoltaic Market
2018
The Italian photovoltaic (PV) marketis analyzed by using the data contained in the database that describes all PV Plants installed in Italy under the incentive program called “2nd Conto Energia”. It is shown that the cumulative probability distribution of the size of the installed PV plants has a broken power tail. An approach to partially quantify the effect of the economic, juridical and technical rules is introduced in order to show how the regulatory body influences the power tail of the cumulative probability curve.
Unfair play? Video games as exploitative monetized services: An examination of game patents from a consumer protection perspective
2019
Video games as a consumer product have changed significantly with the advent of in-game purchasing systems (e.g., microtransactions, ‘loot boxes’). This review examines consumer protections related to in-game purchasing by anticipating some of the potential design strategies that might contribute to higher risk consumer behavior. Attention was directed towards the analysis of patents for potential in-game purchasing systems, with 13 identified on Google Patents. The design features were analysed in relation to the consumer rights and guarantees described in the terms of use agreements of the patent assignees. The analysis revealed that some in-game purchasing systems could be characterized …
Is Democracy Exportable?
2017
Among many aspects to the question of whether democracy is exportable, this contribution focuses on the role of the people, understood not as a unitary actor but as a heterogeneous set: the citizens. The people matter, in a different way, both in the countries to which democracy might be exported and in the democratic countries in which the question is about promoting democracy elsewhere. The mechanisms or characteristics involved in the discussion include yardstick competition, differences among citizens in the intensity of their preferences, differences among autocracies regarding intrusion into private life, citizens’ assessments of future regime change, and responsiveness of elected inc…
Interactively Learning the Preferences of a Decision Maker in Multi-objective Optimization Utilizing Belief-rules
2020
Many real life problems can be modelled as multiobjective optimization problems. Such problems often consist of multiple conflicting objectives to be optimized simultaneously. Multiple optimal solutions exist to these problems, and a single solution cannot be said to be the best without preferences given by a domain expert. Preferences can be used to find satisfying solutions: optimal solutions, which best match the expert’s preferences. To model the preferences of the expert, and aid him/her in finding satisfying solutions, a novel method is proposed. The method utilizes machine learning combined with belief-rule based systems to adaptively train a belief rule based system to learn a domai…
Influencias y prescriptores del consumo teatral. Un estudio sobre el efecto de las críticas teatrales y otras instancias de prescripción en los hábit…
2016
Este artículo analiza la influencia que ejercen diversas instancias de prescripción en los hábitos de asistencia al teatro. El estudio se basa en una encuesta realizada específicamente para esta investigación en la que fueron entrevistadas 210 personas que asistían a una representación teatral en tres salas distintas de la ciudad de Valencia. El estudio ha revelado la importancia del boca a boca en la decisión de asistir al teatro y su mayor influencia entre el público menos asiduo a las representaciones teatrales. Los resultados obtenidos también han puesto de manifiesto la existencia de una estrecha relación entre el efecto prescriptor de las críticas teatrales y las pautas de asistencia …
