Values of games with probabilistic graphs
1999
Abstract In this paper we consider games with probabilistic graphs. The model we develop is an extension of the model of games with communication restrictions by Myerson (1977) . In the Myerson model each pair of players is joined by a link in the graph if and only if these two players can communicate directly. The current paper considers a more general setting in which each pair of players has some probability of direct communication. The value is defined and characterized in this context. It is a natural extension of the Myerson value and it turns out to be the Shapley value of a modified game.
REPEATED GAMES WITH PROBABILISTIC HORIZON
2005
Repeated games with probabilistic horizon are defined as those games where players have a common probability structure over the length of the game's repetition, T. In particular, for each t, they assign a probability pt to the event that "the game ends in period t". In this framework we analyze Generalized Prisoners' Dilemma games in both finite stage and differentiable stage games. Our construction shows that it is possible to reach cooperative equilibria under some conditions on the distribution of the discrete random variable T even if the expected length of the game is finite. More precisely, we completely characterize the existence of sub-game perfect cooperative equilibria in finite s…
Urban poverty: Measurement theory and evidence from American cities
2021
AbstractWe characterize axiomatically a new index of urban poverty that i) captures aspects of the incidence and distribution of poverty across neighborhoods of a city, ii) is related to the Gini index and iii) is consistent with empirical evidence that living in a high poverty neighborhood is detrimental for many dimensions of residents’ well-being. Widely adopted measures of urban poverty, such as the concentrated poverty index, may violate some of the desirable properties we outline. Furthermore, we show that changes of urban poverty within the same city are additively decomposable into the contribution of demographic, convergence, re-ranking and spatial effects. We collect new evidence …
It’s a matter of confidence. Institutions, government stability and economic outcomes
2021
In this paper we analyse the effect of constitutional structures over policy outcomes. In particular, we exploit the heterogeneity in parliamentary systems deriving from the presence and the use of the confidence vote to investigate whether stable and unstable parliamentary systems behave differently in terms of the policies they implement. This finer partition of parliamentary systems allows us to identify effects that are more robust than the ones previously discussed in the literature. We show that the difference between presidential and parliamentary systems documented in previous works is driven by a difference between presidential and stable parliamentary systems. We suggest that poss…
The assessment of parenting in the child welfare practice
1999
Abstract This study analyzed how parenting and factors considered as important determinants of parental care are assessed in the child welfare practice during the placement process, using ethnographic content analysis of case records. The assessment of parenting and the factors affecting it was unsystematic and unplanned with no consistency between cases. The documentary mentions concerning the quality of parent-child relationships were surprisingly rare. The descriptions concentrated more on parents' problems than problems in parenting and the qualities of the parent-child relationship. This study indicated that apart from the need for systematized assessment methods in Finnish child welfa…
Between leader-worship and member’s democracy: The consumer co-operatives in the fascist Italy
2018
En este artículo se analiza el impacto del régimen fascista italiano en el movimiento cooperativista de consumo, tema de interés ya que supone un choque entre una cultura política antidemocrática y una cultura económica democrática. Se intenta demostrar que el régimen fascista penalizó al movimiento cooperativista de consumo de varias formas. Sin embargo, un reducido número de organizaciones constituyeron una excepción a este fenómeno y, paradójicamente, tuvieron un considerable éxito en su funcionamiento desde el punto de vista empresarial. Algunos problemas —tamaño reducido, excesiva inversión social, una visión más política que empresarial— fueron resueltos de manera frecuente por los nu…
Consumo y medio ambiente en el País Valenciano (1980-2000)
2006
At the end of the 1970s, after more than a decade of intense economic development, some marks of the mass consumption model were engraved in the Valencian society: a commercialisation system increasingly dominated by large corporations which trade in worldwide markets and use massive advertising; an animal-protein based diet, with products imported from far-away countries, with a strong presence of highly processed and packaged food and beverage; mobility based on cars; preference for owned housing, sub-urbanisation tendency, and growing energy use; «use-and-dump» culture defined by short life of products and high production of waste. This consumption model is highly homogenous and indicate…
Standard of living, consumption norms, and perceived necessities
2014
Purpose– The purpose of this paper is to focus on the material conditions of peoples’ daily lives by investigating changes in the self-perceived necessities of ten technology- and leisure-related consumer goods and services between 1999 and 2009. The authors also look at the socio-demographic predictors of the perceptions and the development of the ownership of the goods under investigation.Design/methodology/approach– The data are derived from surveys “Finland – Consumption and way of life” 1999 (N=2,417), 2004 (N=3,574), and 2009 (N=1,202). The statistical analysis methods include ANOVA and descriptive statistics. Also official statistics are used.Findings– Many technological goods, in pa…
The impact of mimicry on sales – Evidence from field and lab experiments
2011
A buyer's observation that one or more people are consuming a product can lead that buyer to consume the product as well. The evidence supporting unconscious and unintentional (automatic) mimicry of consumption suggests that it is a pervasive and robust phenomenon. However, up until now most findings on the antecedents of mimicry have been obtained from lab studies. Using a field study, the current research shows that passengers in a train mimic the consumption behavior of other passengers. Two subsequent lab studies suggest that mimicry of consumption is all the more powerful the more people there are consuming and the more intense and consistent their consumption behavior is. However, the…
A Hierarchical Model for Analysing Consumption Patterns in Italy Before and During the Great Recession
2016
The paper aims to explore how the Great Recession of the twenty-first century has impacted on the consumption behaviour of Italian households. Following a hierarchical approach, the study investigates differences in consumption behaviour at both household and regional levels. Using micro data on Italian Household Expenditure for the years 2002, 2006, 2010 and 2012, multilevel and two-step regression models have been estimated. The analysis has been performed for four different consumption categories: food, housing, work-related and leisure. The analysis reveals that the economic crisis led to increasing income elasticity for each category of consumption, especially for food, the most essent…
