Common pool resources and contextual factors: Evolution of a fishermen's cooperative in Calcutta 总被引:1,自引:0,他引:1
The CPR school has successfully rebutted Hardin's pessimistic Tragedy of the Commons model. However, in recent years, critics have focussed on the inward orientation and lack of contextual analysis characterising the writings of the CPR school.Oakerson [A Model for the analysis of common property problems. Working Paper R86-13. Workshop in Political Theory and Policy Analysis, Indiana University, 1986] and Ostrom [Governing the Commons. Cambridge, Cambridge University Press, 1990] have detailed the list of variables that have to be studied to understand the mechanics of collective action. However, these factors are internal to the community. Recent critics' point out that the actions of individual agents are also influenced by the alternatives embedded outside the system. These variables are collectively labelled contextual factors.In our paper, we have analysed the case of a fishermen's cooperative in the Calcutta Metropolitan District to show how the historic and economic context shapes targets of resource users and affects the feasibility of alternative courses to achieve the target by determining opportunity and transaction costs of actions. This indicates the importance of contextual factors in explaining the formation and evolution of the resource regime. 相似文献

We examine and compare a large number of generalized autoregressive conditional heteroskedastic (GARCH) and stochastic volatility (SV) models using series of Bitcoin and Litecoin price returns to assess the model fit for dynamics of these cryptocurrency price returns series. The various models examined include the standard GARCH(1,1) and SV with an AR(1) log-volatility process, as well as more flexible models with jumps, volatility in mean, leverage effects, t-distributed and moving average innovations. We report that the best model for Bitcoin is SV-t while it is GARCH-t for Litecoin. Overall, the t-class of models performs better than other classes for both cryptocurrencies. For Bitcoin, the SV models consistently outperform the GARCH models and the same holds true for Litecoin in most cases. Finally, the comparison of GARCH models with GARCH-GJR models reveals that the leverage effect is not significant for cryptocurrencies, suggesting that these do not behave like stock prices. 相似文献

This article seeks to gain an understanding of how members’ characteristics relate to lapsing behavior in paid membership
contexts. Literatures such as social identity theory are used to propose hypotheses that are tested using a hazard rate model
on archival data pertaining to 7,798 members of an art museum. The results indicate that the hazard of lapsing is lowered
with increasing duration, participation in special interest groups whose goals are related to those of the focal organization,
gift frequency, and increasing interrenewal times. Conversely, members who have downgraded their membership level in the past,
those who have participated in special interest groups whose goals are unrelated to those of the focal organization, and those
who received their membership as a gift are more likely to lapse.

We add to the literature on the association of financial knowledge and financial attitudes with financial outcomes by focusing on predominantly low-income Hispanic families. We examine (i) saving for emergencies, for college, and in 401(k) plans, and (ii) ownership of a home, land or rental property, and an investment account. We find that financial knowledge is strongly related to our savings measures and to owning an investment account. Financial attitudes play less of a role, but assume some importance when interacted with financial knowledge. Self-reported financial knowledge in addition to factual financial knowledge is associated with favorable financial outcomes. Our results are important for the upward economic mobility of a demographic group that has received less attention in the literature. 相似文献

This paper takes a fresh look at the determinants of the holding of reserves with the aim of highlighting similarities and differences among emerging markets (EMs), advanced economies (AEs), and low‐income countries (LICs). We apply two panel estimation techniques: fixed effects (FE) and common correlated effects pooled mean group (CCEPMG). FE regression results suggest that precautionary savings’ motives, both current account‐ and capital account‐related, are generally the most important determinants of reserves’ holding for all country groups. Nonetheless, there is considerable heterogeneity across country groups and over time. The intertemporal motive, a novelty of this paper, has gained importance everywhere. The CCEPMG results confirm the importance of precautionary motives and suggest that current account motives matter only for EMs and LICs and capital account motives matter for all groups while being more relevant for EMs. The CCEPMG results also point to the importance of taking into account the heterogeneous impact of unobserved common factors that affect coefficient estimates and the dynamic process through which reserves adjust to changes. 相似文献

Consumers are increasingly reading online reviews before making any purchasing decisions. The significance of online reviews has only grown over the years. Though in the past, scholars have emphasized the impact of quantitative factors (e.g., review ratings) on online reviews, only recently have they begun to explore the role of qualitative aspects of online reviews. Content readability and associated sentiments in text provide two important qualitative cues that influence the helpfulness of online reviews. However, the extant literature has overemphasized the linear association between these aspects and the helpfulness of reviews. Using the elaboration likelihood model and the classic ideal point concept, the current work asserts that after an ideal point is attained, lucid and sentimental reviews diminish in utility (i.e., helpfulness of an online review for consumers decreases). This may happen because consumers are wary of fraudulent reviews. This study proposes that if experienced reviewers give such extreme reviews, then consumers might still draw utility from these reviews. In other words, this study explains the moderating role of reviewer experience, which heuristically influences consumers’ trust of online reviews, thus making even too simplistic or extremely sentimental reviews helpful. 相似文献

The objective of this research work is to study the progress of research on technological uncertainties, social uncertainties and emerging markets and outline and identify the key disciplines, journals, articles and authors. For this the author studied the existing literature from the various fields in which technological uncertainties, social uncertainties and emerging markets research work have been published using ISI Web of Knowledge database. The paper finds that there is increasing research work on technological uncertainties, social uncertainties and emerging markets and the bibliographical search resulted in ninety-one documents written by one-hundred-sixty-one authors in eighty-four journals in seventy-two disciplines. The five major disciplines and their underlying journals are business and economics, agriculture, psychology, public administration, and environmental sciences and ecology accounting for majority of publications. In journals the most prolific, measured by number of articles published are Harvard Business Review, Social Science and Medicine, World Development, and Higher Education; and most influential, measured by the global citation received, are Harvard Business Review, Social Science and Medicine and Sociological Review. The top 10% of the journals are responsible for 23% of all publications but 85% of all global citations received. This highlights that despite the high, diverse and increasing number of journals; only few are dominating and shaping the research arena of technological uncertainties, social uncertainties and emerging markets. Further, in the ten most cited articles, no author appears more than once. 相似文献

Effects of age, need for cognition, and affective intensity on advertising effectiveness 总被引:1,自引:0,他引:1
This paper explores how individual characteristics of age, need for cognition (NFC), and affective intensity (AI) interact with each other and with advertising appeal frames (i.e., rational, positive-emotional, negative-emotional) to influence ad attitudes, involvement, and recall. The mixed design study reveals that younger adults recall emotional messages, especially negative ones, better than rational ones, but recall does not differ for older adults across appeal frames. Older adults prefer rational and positive messages to negative-emotional messages but ad attitudes do not differ among younger adults across appeal frames. Finally, age interacts with AI, but not NFC, to influence ad responsiveness. Both age and AI influence ad attitudes such that older adults exhibit the most positive ad attitudes across all appeal frames. 相似文献
