‘Hybrid’ open source software virtual communities of practice – a conceptual framework

‘Hybrid’ open source software communities are conducive to knowledge integration and innovation, and can be seen through a community of practice lens. In this paper, we develop an integrated process theory of structural attributes and social mechanisms of hybrid virtual communities. We offer a dynamic view of knowledge integration and innovation in such communities. We also emphasise the multi-faceted nature of virtual communities and identify factors that regulate participation and sustain such communities. This has implications for theorising about knowledge integration and innovation in hybrid virtual settings. Finally, virtual ethnography and multi-level research are suggested for future research.     

Household internal and external electricity contract switching in EU countries

Using a representative sample of more than 13,000 households from eight countries in the European Union (EU), this article empirically studies the factors related to household electricity contract switching by distinguishing between internal switchers (households that switched contracts but stayed with the same supplier) from external switchers (households that switched to a new supplier). The econometric analysis includes individual preferences, household structural factors and socio-demographic characteristics, as well as electricity market characteristics. The study explicitly explores the role of risk and time preferences on switching behaviours, with risk and time preferences elicited through incentivized experiments as well as self-assessment scales. The main results suggest that internal and external switching are not related to the same factors, that risk and time preferences affect switching behaviours, and that renters are less likely to switch than homeowners; further, electricity market characteristics are found to affect household electricity contract switching.     

Jewish emancipation and schism: Economic development and religious change

This paper studies the impact of Jewish Emancipation and economic development on Jewish religious culture in 19th century Europe. In Germany, a liberal Reform movement developed in response to emancipation, while Ultra-Orthodox Judaism emerged in eastern Europe. We develop a historical narrative and model of religious organization that accounts for the polarized responses by Jewish communities. Our explanation is based on a tradeoff between time and money contributions. A religious organization chooses between a relatively affluent community that expends little effort on religious participation and a poorer community that devotes a large amount of time and effort to religious activity. Political and economic development shape this tradeoff in unexpected ways, leading to complex forms of behavior such as religious schisms and cycles. When preferences are transmitted intergenerationally, organizations tend to be more conservative. Our historical narrative points to further extensions of extant models of religion, as well as providing broader insights into cultural integration and religious change.     

A cardinal approach to straightforward probabilistic mechanisms

In every probabilistic mechanism, society selects an alternative, through a random device, out of a subset of indifferent alternatives. Consequently, in this context individuals face uncertainty and value the different lotteries on alternatives by their expected utility, so that they make use of a Von Neumann-Morgenstern cardinal utility function. Surprisingly, the social choice approach to probabilistic mechanisms assumes the use of ballots which preclude the complete expression of behaviour towards risk: individuals can only announce their ordinal preferences, or an approximation of their cardinal preferences, since in any case only a finite number of representations of preferences is available. This paper attempts to study voting systems in which individuals can express the cardinality of their preferences by assigning weights to the alternatives. It is shown that by voting with ballots which reflect weighting a new class of straightforward probabilistic mechanisms is defined, and that this class strictly contains the class of probabilistic straightforward mechanism designed by Gibbard.     

Seasonal fluctuations and equilibrium models of exchange rate

Most of the evidence on dynamic equilibrium exchange rate models is based on seasonally adjusted consumption data. Equilibrium models have not worked well in explaining the actual exchange rate. However, the use of seasonally adjusted data might be responsible for the spurious rejection of the model. This article presents a new equilibrium model for the exchange rates that incorporates seasonal preferences. The fit of the model to the data is evaluated for five industrialized countries using seasonally unadjusted data. Our findings indicate that a model with seasonal preferences can generate monthly time series of the exchange rate without seasonality even when the variables that theoretically determine the exchange rate show clear seasonal behaviours. Further, the model can generate theoretical exchange rates with the same order of integration than actual exchange rates, and in some cases, with the same stochastic trend.     

Urban and rural attitudes toward municipal water controls: A study of a semi-arid region with limited water supplies

This study addresses the effectiveness of using pricing mechanisms, government-imposed constraints, or a hybrid, as a means of rationing municipal water. We try to test which policies would be most accepted among rural and urban communities in a semi-arid region of Texas that depend on both surface and groundwater sources for their municipal supplies. This study reveals that a hybrid conservation policy that includes mandatory restrictions, fines for overuse, and pricing increases could be more acceptable, and hence more efficient, than a policy that only consists of regulation. Moreover, there is not a significant dichotomy in policy preferences between rural and urban constituents; although those in rural communities would seem to appreciate far less regulatory policy than would urbanites.     

A Popular Geopolitics of the Refugee Crisis in Europe: The Re-actualization of Identity-driven Geopolitical Narratives in Estonia

ABSTRACT

The article examines the question of how the refugee crisis in Europe re-actualizes the existing national geopolitical narratives and affects the border-(re)drawing of European political communities. I particularly refer to the Estonian experience, which I examine through two different case studies. The first one focuses on the refugee issue as seen from the perspective of fostering a less nationalistic and more heterogeneous identity in Estonia, expressed in the language of contemporary art. The second one addresses the perceptions of the refugee debate by Russian speakers in Narva who directly relate this question to their personal experiences with integration into Estonian society since the fall of the Soviet Union. I analyse both issues within the framework of popular geopolitics that tackles cultural representations of territories, spaces, and identity politics from the viewpoint of vernacular, home-grown, and routine meanings, to bring this culturally focused approach to the foreground of research into politically sensitive phenomena.     

Existence of equilibrium and stratification in local and hierarchical Tiebout economies with property taxes and voting

Summary. This paper present the first fully closed general equilibrium model of hierarchical and local public goods economies with the following features: (i) multiple agent types who are endowed with both some amount of private good (income) and a house, who are mobile between houses and jurisdictions, and who vote in local and national elections; (ii) multiple communities that finance a local public good through property taxes which are set in accordance with absolute majority rule; and (iii) a national government that produces a national public good financed through an income tax whose level is determined through majority rule voting. In contrast to previous models, no overly restrictive assumptions on preferences and technologies are required to prove the existence of an equilibrium in the presence of property taxation and voting. Thus, the existence of an equilibrium is proved without any of the major restrictions used in the past, and sufficient conditons for stratification of agents into communities based on their public good preferences and their wealth levels are found. This model lays the groundwork for a positive applied analysis of local public finance and intergovernmental relations. It furthermore builds the foundation for the first parameterized computable general equilibrium model of local public goods and fiscal federalism.

COURSE BIDDING AT BUSINESS SCHOOLS*

Mechanisms that rely on course bidding are widely used at business schools in order to allocate seats at oversubscribed courses. Bids play two key roles under these mechanisms: to infer student preferences and to determine who have bigger claims on course seats. We show that these two roles may easily conflict, and preferences induced from bids may significantly differ from the true preferences. Therefore, these mechanisms, which are promoted as market mechanisms, do not necessarily yield market outcomes. We introduce a Pareto‐dominant market mechanism that can be implemented by asking students for their preferences in addition to their bids over courses.     

How pervasive is the effect of culture on stock market linkages? Evidence across regions and economic cycles

We conduct a comprehensive study on the effect of culture on stock market linkages. With data on 25 national stock markets, a quantile regression model is used to estimate the determinants of market linkages using culture variable/s such as language, religion and Hofstede’s cultural dimensions while controlling for distance, economic and legal variables. Further, we test whether these effects hold across regions and if changes are detected during periods of market crisis. We also test if market liquidity, an indicator of market efficiency, diminishes the impact of culture on market linkages. The main conclusion is that culture preferences shape investor choices, which affects integration between stock markets. The equity markets with similar cultural traits tend to increase market linkages; however, we observe differences across regions. Furthermore, liquidity and economic uncertainty fail to have an impact on the significance of culture variable/s as determinants of market linkages.     

Cooperation and cultural transmission in a coordination game

The aim of this paper is to analyze if cooperation can be the product of cultural evolution in a two-stage coordination game, consisting of a production stage followed by a negotiation phase. We present an overlapping generations model with cultural transmission of preferences where the distribution of preferences in the population and the strategies are determined endogenously and simultaneously. There are several groups in the society; some of them play cooperatively and others do not. Socialization takes place inside the group, but there is a positive rate of migration among groups which parents anticipate. Our main result shows that all groups converge to the cooperative equilibrium.     

Achievement Bias in the Evolution of Preferences

Currently, economists' models of the evolutionary selection of utility function parameters are generally based on two assumptions. First, it is assumed that utility parameters must serve Darwinian fitness, in the sense that individuals who maximize utility are also maximizing their biological survivability. Second, it is assumed that utility parameters accurately reflect well-being, in the sense that individuals who maximize utility also maximize their happiness. However, there is a large literature in anthropology, biology, and psychology suggesting that these two assumptions may not be warranted. Focusing on utility and happiness, the paper uses models of cultural selection to show that there is no guarantee that our evolved preference must be the preferences that maximize our happiness. Instead, there are plausible mechanisms of cultural selection that will allow immiserating preferences to persist in steady state equilibrium. These mechanisms are generally related to the concept of social achievement: those who achieve more in society will have a greater influence on the utility parameters of the next generation, and this influence is independent of the achievers' well-being. Thus, a preference is more likely to survive if it satisfies some mix of achievement goals and happiness goals, rather than just happiness goals alone.

Customer preferences versus managerial decision-making in open innovation communities: the case of Starbucks

Customers can participate in open innovation communities posting innovation ideas, which in turn can receive comments and votes from the rest of the community, highlighting user preferences. However, the final decision about implementing innovations corresponds to the company. This paper is focused on the customers' activity in open innovation communities. The aim is to identify the main topics of customers' interests in order to compare these topics with managerial decision-making. The results obtained reveal first that both votes and comments can be used to predict user preferences; and second, that customers tend to promote those innovations by reporting more comfort and benefits. In contrast, managerial decisions are more focused on the distinctive features associated with the brand image.     

Goals,rationality criteria and market functioning ∗

The behaviours of economic operators may be directed by goals and rationality criteria other than those postulated by neoclassical theory. Under certain conditions, the existence of deviant goals and rationality criteria, far from being eliminated by the process of ‘natural selection’, has a profound effect on market functioning. It alters the ‘natural selection’ criterion and thereby influences the market trajectory. It can also favour the development of specific mechanisms of co-ordination. Our hypothesis is illustrated by an analysis of the cultural markets.     

Global public goods and unilateral matching mechanisms

While conventional agreements on international public goods require bilateral or multilateral cooperation, we show that unilateral action through matching mechanisms with a self‐commitment device can possibly generate Pareto‐improving outcomes. Even without commitment, unilateral matching may also benefit both players at corner situations. We further characterize the conditions under which this desirable outcome is achieved, particularly highlighting the role of the income distribution and its interplay with the preferences. Moreover, we propose a variant of unilateral matching that can generate Pareto‐improving outcomes regardless of the preferences and the income distribution, indicating that income inequality may not be an obstacle for improving public good provision through unilateral matching.

Strategic Interaction Among Local Governments in Japan: An Application to Cultural Expenditure

In the context of limited local government resources, cultural expenditures are often targeted for reduction. In Japan in particular, with its aging population, cultural expenditures have low priority. This paper examines whether or not local governments strategically influence each other with respect to cultural spending, using data from Japanese local governments. By estimating the reaction functions for local cultural expenditures, we find that there exists free‐rider behaviour between local cultural expenditures that produce beneficial spillover effects. We also find a larger free‐rider incentive the shorter the distance between neighbouring regions, the shorter the travel time between neighbouring regions, and the larger the neighbouring region's population. Furthermore, our results reveal that the provision of cultural services through intergovernmental strategic behaviours is more elastic with respect to the relative change of the distance or the travel time among neighbouring regions than to that of the population size among neighbouring regions.
