Auctioning goods is a widespread practice, particularly in the agricultural sector. The outcome of auctions can be affected by various factors. One of these factors can be anchoring effects, which describe the influence of present available information on numerical values in human decisions. However, the influence of anchoring effects in auctions carried out offline – that is, live events that are not taking place on the internet – is largely unknown. For this reason, we analyze anchoring effects of exogenously provided values using an experimental common value auction with entrepreneurs. In total, 48 groups each made of five farmers participate in a series of four auctions for envelopes containing a €10 banknote with a 50% probability of occurrence. Our results indicate that anchoring based on exogenously presented values can either result in negative adjustment in open bid auctions, or no adjustment in closed-seal bid auctions. Furthermore, the results show that previous bids affect following bids, which may also be an anchoring effect.  相似文献

Adverse childhood experiences might have long-lasting effects on decisions under uncertainty in adult life. Merging the European Survey on Health, Ageing and Retirement with data on conflict events during the Second World War, and relying on region-by-cohort variation in war exposure, we show that warfare exposure during childhood is associated with lower financial risk taking in later life. Individuals who experienced war episodes as children hold less – and are less likely to hold – stocks, but are more likely to hold life insurance, compared to non-exposed individuals. Effects are robust to the inclusion of potential mediating factors, and are tested for nonlinearity and heterogeneity. Moreover, we provide evidence of hedonic adaptation to war, as high and low intensity of war exposure have comparable long-term effects. We also document that war exposure in childhood increases sensitivity to financial uncertainty since exposed-to-war individuals are less likely to hold stocks after periods of high volatility. Finally, we shed light on the most likely mechanism in the relationship between war exposure and financial risk taking – i.e., enhanced sensitivity to uncertainty – and we show that preferences, and not beliefs, channel this relationship.  相似文献

Conclusion My basic point is simple: OSHA, in its zeal to ensure safer workplaces, should remember that its primary task as a regulatory agency is to correct market failures and should tailor its regulatory solutions to respond to market failures efficiently. The most efficient solution to a market failure will generally be the least restrictive regulatory alternative, for such an alternative maximizes the ability of individual actors to engage in wealthcreating private ordering. With respect to inadequate ergonomic protections in the workplace, the culprit market failure is not a negative externality but is — if there truly is a market failure — systematic informational inadequacies on the part of employees (about ergonomic risks) and employers (about available precautions). The most narrowly tailored regulatory solution, and therefore the one most likely to preserve the wealth-creation benefits of private ordering, would focus on providing the systematically under-produced information to the relevant actors.  相似文献

Public protest events are now both social media and news media events. They are deeply entangled, with news media actors – such as journalists or news organisations – directly participating in the protest by tweeting about the event using the protest hashtag; and social media actors sharing news items published online by professional news agencies. Protesters have always deployed tactics to engage the media and use news media agencies’ resources to amplify their reach, with the dual aim of mobilising new supporters and adding their voice to public, mediatised debate. When protest moves between a physical space and a virtual space, the interactions between protesters and media stop being asynchronous or post hoc and turn instantaneous. In this new media-protest ecosystem, traditional media are still relevant sources of information and legitimacy, yet this dynamic is increasingly underpinned by a hybrid interdependency between traditional news and social media sources. In this paper we focus on an anti-austerity government movement that arose in Australia in early 2014 and was mobilised as a series of social media driven, connective action protest events. We show that there is a complex symbiotic interdependency between the movement and the traditional media for recognition and amplification of initial protest events, but that over time as media interest wanes, the movements’ network becomes disconnected and momentum is lost. This suggests that the active role traditional media play in protest events is being underestimated in the current research agenda on connective action.  相似文献

We consider two rival hypotheses on the emergence of organization in open production communities. According to the first (“reputation hypothesis”), patterns of agreement and disagreement among participants in open production communities are explained by differences in individual reputation for quality of contribution. The reputation hypothesis predicts that participants will tend to agree with more reputable others and disagree with less reputable others thus contributing to establish a stable open production community. According to the second hypothesis (“balance hypothesis”), patterns of agreement and disagreement are explained by membership in sub-communities of “friends” and “enemies.” The balance hypothesis predicts that participants in open production communities will agree mainly with friends and disagree mainly with enemies, regardless of considerations about reputation for the quality of their contributions. In this paper, we examine which one of these hypotheses is more consistent with patterns of positive and negative interaction events observed during the production of the complete set of 1,206 English-language Wikipedia articles officially considered controversial. We specify and estimate new models for signed and weighted relational event networks predicting the probability that a user deletes the contributions of another user – thus expressing personal disagreement – and/or protects the contributions of another user against deletion from third parties – thus expressing personal agreement. In an analysis of positive and negative interaction among Wikipedia contributors consisting of more than 60 million observations, we find strong support for the balance hypothesis and for the predictions of the reputation hypothesis that are more consistent with alter-centric interpretations of social status as conferred by alters through observable acts of deference.  相似文献

Information campaigns to increase tax compliance could be framed in different ways. They can either highlight the potential gains when tax compliance is high, or the potential losses when compliance is low. According to regulatory focus theory, such framing should be most effective when it is congruent with the promotion or prevention focus of its recipients. Two studies confirmed the hypothesized interaction effects between recipients’ regulatory focus and framing of information campaigns, with tax compliance being highest under conditions of regulatory fit. To address taxpayers effectively, information campaigns by tax authorities should consider the positive and negative framing of information, and the moderating effect of recipients’ regulatory focus.  相似文献

We assess who among migrants is likely to choose unauthorized migration. While the literature has addressed reasons for unauthorized migration, we are the first to model individual choice of actual unauthorized migration. By using data from Albanian return migrants, we can ascertain that we capture actual migration – behaviour – rather than intentions to migrate, and respondents have no incentives to hide unauthorized migration as there are no consequences at this stage. At the individual level, unauthorized migration in a context of circular migration is linked to being young and male – interpreted as risk‐taking individuals – and being free of social responsibilities like having a partner or children. Social responsibilities appear to moderate the impact of risk‐taking on choosing unauthorized migration.  相似文献

Evidence regarding the effects of health status on migration are mixed, with some concluding that there is a positive relation while others conclude a negative relation. This study examines the analytical bases for conflicting findings and proposes a model of the health-migration relation which allows for age selectivity, nonlinearities, interactions, and dynamic effects. Often in migration research we focus on migrant-nonmigrant differentials, which helps us to understand the cross-sectional differences between the 2 groups of persons, but it does little to elucidate the complex process by which nonmigrants become migrants. The sequence of migration and health events, from the US National Health Interview Survey from 1979-1980, show that for the population under age 45, there is little temporal connection between migration and health status changes. 2/3 of the younger population with at least 1 health or migration event migrated only, with health status changes neither preceding nor following the migration. Since the migration and health events for these persons are not associated in time, there is little basis for positing strong relations of either direction for the nonelderly. The age groups for which migration and health events are connected in time are those over age 45, and the temporal proximity becomes even more marked for the elderly. Among the elderly, the migrant-only group constituted only 10% of those with at least 1 event. As expected, for the elderly the dominant relation is health deterioration after migration, the pattern displayed by 65% of the elderly with events in the last 5 years. The elderly are also more likely to be in the Destabilized Migrant category, experiencing health status declines both before and after migration. This is also consistent with the theory that the elderly in poor health at the time of migration will be more likely to be stressed by their migration and experience further deteriorations in health. The conditional probabilities indicate that health status declines are unlikely to precipitate immediate migrations, except for those with pre-existing serious conditions or more severe activity limitations.  相似文献

Investigations into the option framing effect involve the use of a subtractive versus an additive option-framing method to gauge their impact on consumer behaviors. This research examines how option framing could affect choice decisions as a function of a consumer’s goal orientation. Study 1 offers convergent support for the proposition that regulatory focus moderates the option framing effect and the mediating role of action/inaction on the relationship between regulatory focus and the option framing effect. In particular, a reverse finding shows that promotion-focused consumers provided with a +OF options list tend to choose more options than those who are given a −OF option list. To explain the reverse effect, Study 2 examines and demonstrates regulatory fit as a possible moderator. The results of Study 2 also confirm our inference and echo the same results of Study 1. Finally, based on the regulatory fit theory, Study 3 examines if cognitive constraints associate with a consumer’s regulatory orientation may also account for the interaction between regulatory focus and option framing. The results of Study 3 also support the proposition.  相似文献

We challenge the common idea that solidarity has positive, whereas conflict has negative implications, by investigating intergenerational ambivalence – defined as the co-occurrence of solidarity and conflict – and relationship quality. We use representative data on non-coresident adult children and parents with high levels of contact (weekly or more; N = 2,694 dyads). Results show that over half of high contact parent–child ties can be characterized as ambivalent and of high-quality. The likelihood of negative instead of positive ambivalent ties is greater if adult children have few exit options because they are socially isolated or have a small number of siblings. Ties between fathers and sons, and those between caring daughters and aging parents also have a high probability of belonging to the negative ambivalent type.  相似文献

This study deals with the tensions and contradictions between resource governance, welfare policies, and the constitutionally recognized rights of nature and the indigenous peoples in Bolivia and Ecuador. We have identified a certain reductionism in current debates on these issues and propose a more systematic analytical focus on class and the class-ethnicity duality, as expressed in historical and contemporary indigenous struggles, and also confirmed via our ethnographic material. Drawing on the double bind as expressed in Joseph Heller’s Catch-22 wherein the protagonists face situations in which they do not have any choice to achieve a net gain, this article centres on how national governments have to choose between the protections of rights – in this case ethnic and environmental rights – and welfare provision financed by extractive revenues. From the perspective of ecologically concerned indigenous actors, the Catch-22 is articulated in the choice or compromise between universal welfarism on the one hand, and ethno-environmental concerns on the other hand. The article draws primarily on ecosocialist arguments and on indigenous-culturalist perspectives on Good Life (Sumak Kawsay or Vivir Bien). A central finding is the existence of awareness among involved actors – oppositional movements and government authorities – that the Catch-22 quandary and joint class-ethnic concerns are unavoidable ingredients in their discourses, struggles, and understandings of Good Life.  相似文献

Perception of Western governments’ hostility to Islam is one of the indicating features of Islamic fundamentalism and, in some cases, is serving as a pull to join extremist groups. In this paper, using data from two waves of a cross‐national survey, we investigate what affects European Muslims’ opinions about Western governments. We find that residential segregation is associated with perceived hostility of Western governments to Islam. Further, we find that Muslims living in segregated neighbourhoods and enclaves have a higher probability of believing that Western governments are hostile to Islam. National origins of Muslim immigrants have a significant impact, with people from African countries measuring less perceived hostility than others. We also find that education is associated with perceived hostility of Western governments to Islam in a non‐linear way. People with the highest and lowest levels of education tend to be less likely to believe that Western governments are hostile to Islam, relative to people with mid‐level education. This non‐linear effect is best explained by education’s differential effects on perceptions of key world events. During the time between 2011 – before ISIS’s announcement of its Caliphate in Iraq and Syria – and 2013, subsequent to that announcement, we see a sharp decrease in perception of Western governments’ hostility to Islam, particularly among more educated European Muslims. We make the case that this decrease can be attributed, in some ways, to the emergence of ISIS. We discuss our findings in terms of theoretical and policy implications.  相似文献

Considerable evidence has suggested that problem gambling may be transitory and episodic, with gamblers routinely moving in and out of clinical thresholds. Findings in qualitative and quantitative studies have converged on identifying preliminary evidence for the role of life events as motivators and contributing factors for gambling changes over time. The aim of this study was to conduct an exploratory analysis of the relationship between life events, their respective experience as positive or negative, and gambling trajectories among problem gamblers intending to quit. Life event occurrence and ratings as positive or negative, and changes in gambling severity were analyzed over a 12-month period for 204 adult problem gamblers intending to reduce or quit their gambling. Overall, mixed effects models revealed several relationships between life events and both the magnitude and direction of gambling change over time. In particular, gamblers who experienced a greater number of positive events or specific events such as legal events, the adoption/loss of a child, or negative changes to their social relationships, finances, work environments or social/health activities were more likely to exhibit greater gambling reductions over time. Conversely, gamblers who experienced a greater number of negative events, such as family bereavement, the dissolution of a marriage, or negative changes to their residence exhibited smaller gambling reductions or increases in gambling severity. Possible mechanisms which may explain the findings and the importance of examining the subjective experience of life events are discussed. Recommendations for future studies examining associations between life events and gambling trajectories are provided.  相似文献

Despite the prevalent assumption among scholars of social movements and contentious politics that transformative contentious events are also the focus of public attention and discussion, there has been little attempt to substantiate this. After making a case for why to focus on focusing events and suggesting that these events should be thought of as products of a dialogical contentious meaning‐making process, we develop a coverage attribute‐based method for identifying focusing events. For illustrative purposes, we apply our method to the coverage of contentious events during the “first” intifada by Israeli‐Jewish, Jewish settler, and Palestinian newspapers. Findings from analyses of 11,868 news items reveal that newspapers are likely to strategically quiet contentious events that are strategically amplified by newspapers affiliated with opposing or targeted parties, and vice versa, depending on their interpretation of these events as political opportunities or threats. Analyses of variations across and within contending parties reveal the role of structure and agency in the dialogical seesaw‐like dynamics of contentious meaning‐making.  相似文献

This paper seeks to reveal the many ways in which the Communist Party of Greece (KKE) influenced the Cypriot Left (AKEL) during the 1940s. The analysis centres on the main political events of the decade and details the reaction of AKEL, especially as it was reporting to the KKE. Attention then switches to AKEL's ideology and tactics and how these were developed during and because of the Greek civil war. What this paper brings to the discussion is that the advice and control given by the KKE to AKEL – and at the same time the Cold War, which was a playing field on which a political party had to choose a side – were the main factors that formed the identity and ideological framework practiced for decades by AKEL.  相似文献

A low recidivism rate is a goal for any criminal justice system. Poor post‐release outcomes are not random events, however. Some groups are more likely than others to recidivate. This paper will review the literature on inequality in recidivism rates, concentrating on the effects of race and sex. The probability of recidivating is not a randomly distributed event; men are more likely than women to recidivate, and Blacks more likely than Whites, with Hispanics in between. This paper will also address some of the promises (and challenges) that researchers face when trying to identify the causes of race and sex gaps in recidivism rates. This paper will end with recommendations for how to study inequality in recidivism in the future, with the key being to identify the social mechanisms that underlie these consistently unequal outcomes of our corrections system.  相似文献

In the present study, self-generated responses to a question regarding reasons for gambling from two epidemiological surveys were combined and placed into another earlier motivational model for alcohol use, adapted for gambling. Of the 3601 reasons, 954 could be categorised into the model's categories: (a) coping motives (internal, negative reinforcement); (b) enhancement motives (internal, positive reinforcement); and (c) social motives (external, positive reinforcement). Results indicate that coping gamblers experienced greater gambling severity and psychopathology, enhancement gamblers were most likely to gamble while intoxicated and social gamblers were more likely to choose socially-related gambling. An examination of remaining motives suggests additional categories may be warranted – specifically financial and charitable reasons. These findings offer some support for the model; however, it may need to be expanded to account for other motives. The study highlights the advantages and limitations of using self-generated reasons to study gambling motivation.  相似文献

ABSTRACT

The present study looks at the interaction between daily experiences in the workplace – daily workload and daily coworker support – and examines its influence on negative affect and its subsequent impact on same-day work–family conflict (WFC). It proposes two competing moderation hypotheses (buffering vs. intensifying). According to the COR theory, support received from coworkers represents a resource that should buffer the relationship between daily workload and same-day WFC, because it should prevent individuals from experiencing negative affect triggered by high workload episodes which represents a threatening or stressful situation. In contrast, the threat to self-esteem model posits that receiving social support may engender feelings of indebtedness or helplessness at the time such support is provided, thereby amplifying the impact of workload experience on same-day WFC via an increased negative affect. Data collected from 130 pharmacists over 5 consecutive days were analyzed through multilevel structural equation modeling. The results support the hypothesis of the intensifying conditional indirect effect, and show that when individuals are provided with coworker support while experiencing high workload, negative affect is aggravated and hence, in turn, same-day WFC increases. This challenges the mainstream hypothesis that views social support as an important resource in protecting people from stressful events.  相似文献

More and more migrant parents choose to bring their children with them to their migration destination in China. Here, the data reported by China's Health and Family Planning Commission in 2017 are used to examine the influence of migrant children on migrant mothers’ employment. The results showed that migrant children have a negative effect on mothers’ employment and reduce wages of mothers who are work. In addition, considering migrant children’s age, we find that as it increases the burden of childcare is lighter; the probability of mothers’ participation in the labour market and receiving a high wage is higher. Furthermore, in terms of mothers’ characteristics, older age and better education, having a spouse or parents who migrated, longer migration history and an across-provincial move have positive effects on migrant mothers’ employment.  相似文献
