Nationalism,cognitive ability,and interpersonal relations

Interpersonal relations are shaped by the judgements associated with the social categories that individuals perceive in their social contacts. I develop a model of how those judgments form based on a theory of symbolic values. The model depicts the interaction between two values, one associated with an inherited ethnic trait (“nationality”) and one with an endogenous achievement trait (“income”). Individuals with lower cognitive ability are predicted to invest more value on nationalism and to have hostile relations with immigrants. Multiple equilibria are possible, and better schooling may eliminate equilibria with xenophobia. Econometric findings based on data from three large surveys corroborate the predictions derived from the theoretical model.     

“创而不业”为哪般？象征性创业形成机理研究——基于扎根理论的分析

创业活动日益活跃的同时，“创而不业”现象也随之增多，此类创业与传统意义上的创业在行为表现、创业动机等方面有本质的区别，但未引起学术界足够重视。基于此，运用扎根理论选取13个案例，探讨象征性创业类型、形成路径与机理。研究发现：①象征性创业与实质性创业行为表现差异源于创业动机不同，后者追求创业的实质意义，即通过机会识别与开发实现价值创造，而前者则是在象征意义驱动下的行为选择；②根据外部诱因与动机不同，象征性创业具体细分为传染型、策略型和表演型3类，可分别采用社会比较理论、信息不对称理论和印象管理理论加以解释；③3类象征性创业形成机理存在显著差异。其中，传染型创业是由同群创业唤醒负面情绪而引发的模仿行为，其主要目的是修复心理落差，策略型创业是利用信息优势进行政策“套利”的一种手段，表演型创业则是为缓解社会规范压力而开展的印象管理行为。研究结论为深化创业动机研究和理解创业行为差异提供了参考依据。     

Symbolic values, occupational choice, and economic development

Channeling human resources into occupations with high social productivity has historically been a key to economic prosperity. Occupational choices are not only driven by the material rewards associated with the various occupations, but also driven by the esteem that they confer. We propose a model of endogenous growth in which occupations carry a symbolic value that makes them more or less attractive; the evolution of symbolic values is endogenously determined by purposive transmission of value systems within families. The model sheds light on the interaction between cultural and economic development and identifies circumstances under which value systems matter for long-run growth. It shows the possibility of culturally determined poverty traps and offers a framework for thinking about the transition from traditional to modern values.     

Public Goods,Social Norms,and Naïve Beliefs

An individual's contribution to a public good may be seen by others as a signal of attributes such as generosity or wealth. An individual may, therefore, choose their contribution so as to send an appropriate signal to others. In this paper, we question how the inferences made by others will influence the amount contributed to the public good. Evidence suggests that individuals are naïve and biased toward taking things at “face value.” We contrast, therefore, contributions made to a public good if others are expected to make rational inferences versus contributions if others are expected to make naïve inferences.     

The challenge of understanding decisions in experimental studies of common pool resource governance

Common pool resource experiments in the laboratory and the field have provided insights that have contrasted to those derived from conventional non-cooperative game theory. Contrary to predictions from non-cooperative game theory, participants are sometimes willing to restrain voluntarily from over extracting resources and use costly punishment to sanction other participants. Something as simple as face-to-face communication has been shown to increase average earnings significantly. In the next generation of experiments, both in the laboratory and in the field, we need to extract more information that provides insight concerning why people make the decisions they make. More information is needed concerning attributes of individuals as well as the social and social-ecological context in which they interact that may give rise to such deviations from theoretical predictions. In the process of extracting more information from participants and the contexts in which they interact, we face several methodological and ethical challenges which we address in this paper.     

What are the consequences of ignoring attributes in choice experiments? Implications for ecosystem service valuation

This paper investigates the sensitivity of choice experiment values 3AL for ecosystem services to ‘attribute non-attendance’. We consider three cases of attendance, namely that people may always, sometimes, or never pay attention to a given attribute in making their choices. This allows a series of models to be estimated which addresses the following questions: To what extent do respondents ignore attributes in choice experiments? What is the impact of alternative strategies for dealing with attribute non-attendance? Can respondents reliably self-report non-attendance? Do respondents partially attend to attributes, and what are the implications of this? Our results show that allowing for the instance of ‘sometimes attending’ to attributes in making choices offers advantages over methods employed thus far in the literature.     

Status‐Seeking in Criminal Subcultures and the Double Dividend of Zero‐Tolerance

This paper offers a new argument for why a more aggressive enforcement of minor offenses (zero‐tolerance) may yield a double dividend in that it reduces both minor offenses and more severe crime. We develop a model of criminal subcultures in which people gain social status among their peers for being “tough” by committing criminal acts. As zero‐tolerance keeps relatively “gutless” people from committing a minor offense, the signaling value of that action increases, which makes it attractive for some people who would otherwise commit more severe crime. If social status is sufficiently important in criminal subcultures, zero‐tolerance reduces crime across the board.     

Non-attendance and dual processing of common-metric attributes in choice analysis: a latent class specification

There is a growing literature that promotes the presence of process heterogeneity in the way that individuals evaluate packages of attributes in real or hypothetical markets and make choices. A centerpiece of current research is the identification of rules that individuals invoke when processing information in stated choice (SC) experiments. These rules may be heuristics used in everyday choice making as well as manifestations of ways of coping with the amount of information shown in choice experiment scenarios. In this paper, using the latent class framework, we define classes based on rules that recognise the non-attendance of one or more attributes, as well as on the addition and the parameter transfer of common-metric attributes. These processing strategies are postulated to be used in real markets as a form of cognitive rationalization. We use a SC data set, where car driving individuals choose between tolled and non-tolled routes, to translate this new evidence into a willingness to pay (WTP) for travel time savings, and contrast it with the results from a model specification in which all attributes are assumed to be attended to and are not added up with parameter preservation. We find that the WTP is significantly higher, on average, than the estimate obtained from the commonly used full relevance and attribute preservation specification.     

Using Choice Experiments to Value the Environment

This paper we outline the “choice experiment” approach to environmental valuation. This approach has its roots in Lancaster's characteristics theory of value, in random utility theory and in experimental design. We show how marginal values for the attributes of environmental assets, such as forests and rivers, can be estimated from pair-wise choices, as well as the value of the environmental asset as a whole. These choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function, and to minimise required sample size. Choice experiments have important advantages over other environmental valuation methods, such as contingent valuation and travel cost-type models, although many design issues remain unresolved. Applications to environmental issues have so far been relatively limited. We illustrate the use of choice experiments with reference to a recent UK study on public preferences for alternative forest landscapes. This study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay.     

The Effects of Changing Cost Vectors on Choices and Scale Heterogeneity

Choice Experiments (CE) are widely used to estimate the values of changes in non-market goods and services. A cost attribute is typically included in a CE questionnaire to enable the estimation of monetary values for changes in the non-market attributes presented. Notwithstanding the central importance of the cost attribute, relatively little research has been undertaken on the impacts of varying cost attribute levels on value estimates, or on individual heterogeneity. In this paper, I present results from mixed logit and generalised mixed logit models that account for unobserved idiosyncratic preference and scale heterogeneity. Respondents are found to anchor their choices on the relative cost levels presented in the survey with results suggesting that people are more sensitive to relative rather than absolute cost vectors. However, the higher cost levels do not lead to significantly higher value estimates, partly because of observed preference heterogeneity towards the environmental attributes. An important observation is that scale heterogeneity is important: accounting for scale— as well as preference—heterogeneity in the generalised mixed logit model leads to significantly improved model fit. The results indicate significant unobserved error variance across respondents, unrelated to whether a high or low cost vector is used.

Digital identity: How users value the attributes of online identifiers

This paper examines online identifiers from an economic perspective. It uses conjoint analysis survey techniques to develop empirical data on how users value the attributes of online identifiers. It is concerned in particular with three issues: (1) the degree to which identified subjects value increasing the scope of an identifier, i.e., the ability to use a single identifier to access services offered by several organizations; (2) the degree to which users’ choice may be constrained by switching costs; and (3) the value individuals place on privacy and data security relative to other attributes such as cost or scope. The survey population was located in South Korea. The results indicate that e-mail addresses dominate the world of online identifiers for ordinary consumers; that consumers highly value increased scope (e.g., single sign-on capabilities) and the security of their private data; and that switching costs are high.     

Public Preferences and Private Choices: Effect of Altruism and Free Riding on Demand for Environmentally Certified Pork

Sales of private goods with affiliated public good attributes have markedly risen in recent years. This fact is difficult to explain within the paradigm of purely self-interested behavior. This paper investigates factors influencing consumer demand for pork products with certifications related to the environment, animal welfare, and antibiotics. Using psychometric scaling techniques, we measure individuals’ degree of altruism and propensity toward free riding. Results of a random parameter logit model applied to choice data obtained from a nationwide survey in the United States indicates that more altruistic individuals are willing to pay more for pork products with public good attributes than less altruistic individuals and free riders. These results indicate that private purchases of goods with public-good attributes are not simply a result of individuals’ perceptions of the ability to mitigate private risks such as food safety, but that individuals are making private choices to affect public outcomes. Results have implications for policy makers weighing the relative costs and benefits of food labeling policies versus bans related to certain livestock production practices.     

The measurement and decomposition of nonuse values: A critical review

We critically review the literature that claims that existence values, or nonuse values in general, are a large and measurable component of total value for certain environmental resources. Our concern is not with the question “do nonuse values exist?” For some individuals they surely do. Rather, our concern is with two interrelated questions: are there operationally meaningful theorems which might lead to the specific measurement of nonuse values, and do we in fact have a body of credible evidence which shows that nonuse values, particularly components of any nonuse value, are “large”? We find nothing in the way of operationally meaningful hypotheses which would permit the estimation of values attributable to specific motives of individuals. We find no credible basis for claims related to either the measurement of existence and other motive-related values or claims for the “large” relative size of such values. In short, we question the conventional wisdom that such values are measurable and that they are significant as a component of total value.     

Corruption and culture: An experimental analysis

Why do some people choose corruption over honesty and others not? Do the social norms and values prevailing in the societies in which they grew up affect their decisions? In 2005, we conducted a bribery experiment and found that, among undergraduates, we could predict who would act corruptly with reference to the level of corruption in their home country. Among graduate students we could not. In 2007, we replicated our result and also found that time spent in the UK was associated with a decline in the propensity to bribe, although this does not explain our inability to predict graduate behaviour. We conclude that, while corruption may, in part, be a cultural phenomenon, individuals should not be prejudged with reference to their country of origin.     

Respect and relational contracts

Assuming that people care not only about what others do but also on what others think, we study respect in a labor market context where the length of the employment relationship is endogenous. In our three-stage gift-exchange experiment, the employer can express respect by giving the employee costly symbolic rewards after observing his level of effort. We study whether symbolic rewards are used by the employers mainly to praise employees or as a coordination device to build relational contracts by manipulating the balance between labor demand and supply in the market. We find that a high proportion of long-term relationships have been initiated by the assignment of symbolic rewards. However, the assignment of symbolic rewards decreases when it becomes clear that the relationship is durable, suggesting that employers mainly use symbolic rewards as a coordination device to initiate relational contracts. Compared to the balanced market condition, assigning symbolic rewards in initial relationships is less likely when there is excess demand in the market and more likely when there is excess supply, i.e., when the relationship is more valuable. Receiving symbolic rewards increases the employees’ likelihood of accepting to continue the relationship with the same employer. It also motivates them to increase their effort further but only when the market is balanced. Overall, the ability to assign symbolic rewards does not give rise to higher profits because it is associated with lower rents offered to the employees on average, leading to lower effort levels.     

Valuation of ecosystem services from rural landscapes using agricultural land prices

Agricultural lands, primarily managed for crops and livestock production, provide various ecosystem services (ES) to people. In theory, the economic value of the service flows that can be captured privately is capitalized into land prices. This study proposes an integrative framework to characterize the ecosystem services associated with agricultural lands. Using that framework, we demonstrate how hedonic analysis of agricultural land prices can be used to estimate the private values of land-based ES. The model is estimated with data from southwestern Michigan, USA. Results suggest that ES values are associated with lakes, rivers, wetlands, forests and conservation lands in rural landscapes. Ecosystem services that support direct use values, such as recreational and aesthetic services, are likely to be perceived by land owners and capitalized in land prices. Some regulating services that provide indirect use values may be partially capitalized in a land parcel's relationship to natural resources and landscapes. Other ES from the land parcel and its surroundings are unlikely to be capitalized due to lack of private incentives, unawareness, or small perceived value. The private ES values measured in this study highlight opportunities to design cost-effective public policies that factor in the value of private benefits from agricultural lands.     

Teams take the better risks

One reason why decision makers are often teams and not individuals may be that team decisions comply more closely with economic rationality. We compare individual and team decisions, when systematic deviations from the expected utility theory (EUT) and the portfolio selection theory (PST) are to be expected. We find almost no evidence for the greater compliance of team decisions with the principles of EUT. However, there is substantial evidence for the consistency of team decisions with the PST. Compared to individuals, teams accumulate significantly more expected value at a significantly lower total risk (measured in standard deviation, S.D.).     

Instrumental cardinal concerns for social status in two-sided matching with non-transferable utility

In this paper we apply the instrumental approach to social preferences in order to distinguish among various shapes of preferences for social status. In particular, we consider the shape of reduced preferences that emerge in the equilibrium of a two-sided matching model with non-transferable utility. Cole et al., 1992, Cole et al., 1995 show that, under full observability of potential mates׳ attributes, instrumental concerns for social status are ordinal, i.e., only one׳s own rank in the distribution of attributes matters. We show that when we depart from full observability, instrumental concerns for social status become cardinal, i.e., also other features of the distribution of attributes matter. We also show that the actual shape of cardinal concerns depends on how individuals can deal with the informational asymmetry, alternatively leading to upward concerns, i.e., making comparisons with higher rank people; downward concerns, i.e., making comparisons with lower rank people; or bidirectional concerns, i.e, being both upward and downward.
