The effects of group composition in a strategic environment: Evidence from a field experiment

Recent theoretical and empirical studies have explored the effect of group membership and identity on individual decision-making. This line of research highlights that economic models focusing on the individual as the sole entity in the decision-making environment potentially miss critical features. This study takes this literature in a new direction by overlaying a field experiment onto a setting where groups have arisen naturally. Our experimental laboratory is large open air markets, where we are able to examine the effects of group membership on seller׳s collusive behavior as measured by prices and surplus allocations. This permits us to explore strategic implications of group composition. Empirical results illustrate the importance of group composition on pricing decisions, and show that deviations from Nash equilibrium are crucially related to group membership.     

Rationality of weather predictions and insurance purchases: testing the gambler’s and hot hand fallacies

Deviations from the rational behaviour assumed in many economic models have been found in a variety of settings. Two such deviations, the gambler’s and hot hand fallacies have been found in lab settings, as well as in consequential real-world decisions. Previous economic experiments have shown that the behaviour of professionals can differ from that of the general population. In this paper, we use data from two experiments conducted with a particular group of professionals who make yearly high-stakes decisions in the face of uncertain weather and market conditions: agricultural producers. In the experiments, participants were asked to make predictions about the coming year’s weather and market conditions and make decisions in a familiar decision context. Results indicate evidence of the gambler’s fallacy, such that participants were less likely to predict a good outcome if the previous outcome(s) were good. We also observe that participants were more likely to gamble if a previous gamble was successful, but find no impact on two successful gambles. These combined results indicate that even professionals with many years of experience can exhibit behaviours that deviate from those assumed by classical models.     

Experiments,policy, and theory in development economics: a response to Glenn Harrison’s ‘field experiments and methodological intolerance’

In ‘Field Experiments and Methodological Intolerance,’ Glenn Harrison develops a criticism of randomized field experiments and denounces ‘intolerance’ for lab experiments and a ‘disconnect from theory.’ We argue that (i) lab experiments and RCTs are based on different methodological approaches and therefore fulfill different scientific objectives; (ii) key features of the RCT methodology make it highly relevant for policy-making, which accounts for a large part of its uptake; (iii) RCTs foster a convergence of interests between policy-makers and researchers around the study of economic mechanisms, which makes it possible to challenge and improve economic theory based on real-world facts; and (iv) hybrid forms of experimentation are being increasingly used and open promising avenues. In sum, economic research based on RCTs is more and more connected to theory and other forms of experiment, while also helping policy-makers tackle daunting problems of poverty and exclusion.     

Using Field Experiments to Change the Template of How We Teach Economics

In this article, the author explains why field experiments can improve what we teach and how we teach economics. Economists no longer operate as passive observers of economic phenomena. Instead, they participate actively in the research process by collecting data from field experiments to investigate the economics of everyday life. This change can be shown to students by presenting them with evidence from field experiments. Field experiments related to factor markets, behavioral economics, and discrimination are presented to explain how this approach works across different economic content. The three questions that are highlighted are the following: (1) Why do women get paid less than men in labor markets? (2) How can we use behavioral economics to motivate teachers? (3) What seven words can end third-degree price discrimination?     

Estimation of Biological and Economic Parameters of a Bioeconomic Fisheries Model Using Dynamical Data Assimilation

A new approach of model parameter estimation is used with simulated measurements to recover both biological and economic input parameters of a natural resource model. The data assimilation technique is the variational adjoint method (VAM) for parameter estimation. It efficiently combines time series of artificial data with a simple bioeconomic fisheries model to optimally estimate the model parameters. Using identical twin experiments, it is shown that the parameters of the model can be retrieved. The procedure provides an efficient way of calculating poorly known model parameters by fitting model results to simulated data. In separate experiments with exact and noisy data, we have demonstrated that the VAM can be an efficient method of analyzing bioeconomic data.     

Measuring the relative productivity of multitasking to sole-tasking in household production: experimental evidence

The standard household production model does not incorporate multitasking, although time-diary data reveal that individuals regularly multitask. We incorporate multitasking into a household production model in which time spent in childcare can be sole-tasked or multitasked with another household production activity and we present the results of an experiment designed to measure the productivity parameters of this model. Because utility and productivity are intertwined and difficult to disentangle in any household production model, we vary the utility pay-offs our experimental participants receive in order to determine how our estimated productivity parameters are affected by a change in the utility parameters. Our estimates of the relative multitasking productivities indicate that, while a minute of sole-tasked time produces more of a single commodity than a minute of multitasked time, total household output increases when two outputs are produced simultaneously, hence confirming the economic motivation for multitasking.     

Rural versus urban preferences for renewable energy developments

Development of renewable energy resources, such as wind farms and hydro-electric schemes, are being promoted as a new method of expanding and diversifying employment in rural areas. However, such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities, such as those based on nature tourism. The authors use a Choice Experiment to quantify peoples' preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of Scotland, focussing in particular on any differences between the preferences of urban and rural dwellers, and on heterogeneity within these groups. Rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration.     

A Feminist Review of Behavioral Economic Research on Gender Differences

This study provides a critical review of the behavioral economics literature on gender differences using key feminist concepts, including roles, stereotypes, identities, beliefs, context factors, and the interaction of men’s and women’s behaviors in mixed-gender settings. It assesses both statistical significance and economic significance of the reported behavioral differences. The analysis focuses on agentic behavioral attitudes (risk appetite and overconfidence; often stereotyped as masculine) and communal behavioral attitudes (altruism and trust; commonly stereotyped as feminine). The study shows that the empirical results of size effects are mixed and that in addition to gender differences, large intra-gender differences (differences among men and differences among women) exist. The paper finds that few studies report statistically significant as well as sizeable differences – often, but not always, with gender differences in the expected direction. Many studies have not sufficiently taken account of various social, cultural, and ideological drivers behind gender differences in behavior.     

Teaching Economics to Trade Unionists

This audience for economic education has special pedagogical and subject matter needs from instructors. The rewards to both, however, outweigh the efforts required.     

Teaching Competition in Professional Sports Leagues

Popular wisdom in affluent countries holds that low wages in poor countries are a magnet for foreign investment, creating public anxiety about the potential threat to domestic employment and wages of capital flight. Historical evidence is provided to show that cheap foreign labor had little effect on foreign investment and the long-term economic performance of today's developed countries.     

The endowment effect and the reference state: Evidence and manipulations

Recent reports suggest that the “endowment effect” may be due to conditions under which it is observed and explained by incentives long recognized in standard theory. Evidence from new experiments, reported here, provides empirical support for the role of the economic environment on people's perceived reference state and consequently on their valuations, as suggested by Köszegi and Rabin [Köszegi, B., Rabin, M., 2006. A model of reference-dependent preferences. Quarterly Journal of Economics 121, 1133–1165], and indicates that the disappearance of the valuation disparity is more likely due instead to conditions that weaken the perception of reference states. Further, these conditions appear to be poor approximations of those that prevail in most cases for which valuations are normally made.     

Facebook-to-Facebook: online communication and economic cooperation

Direct face-to-face communication has traditionally been found to be more effective for fostering economic cooperation than any form of indirect, mediated communication. We inquire whether this is still the case since most young adults routinely use texting and online social media to communicate with each other. We find that young adults in our laboratory public goods experiment are just as adept at finding and sustaining cooperative agreements when communicating within a Facebook group and through online chat as they are in person.     

Learning by Trial and Error: A Case for Moot Courts

This article describes the development of a computer tutorial for use in a history of economic ideas class. An early version of the tutorial contained ten topics, ranging from early Mercantilist thought to Jevons's marginal utility analysis. These concepts were presented in three ways: verbally, graphically, and in summary form. Student critiques were used to extend the content and revise the mode of presentation.     

Teaching Economic Principles Interactively: A Cannibal's Dinner Party

The author describes techniques that he uses to interactively teach economics principles. He describes an experiment on market entry and gives examples of applications of classroom clickers. Clicker applications include (a) collecting data about student preferences that can be used to construct demand curves and supply curves, (b) checking students’ knowledge of central concepts, and (c) playing interactive games that illustrate economic concepts.     

Using choice question formats to determine compensable values: The case of a landfill-siting process

Siting noxious facilities, such as community landfills, is a challenging problem for local planners who recognize the importance of economic efficiency and equity, political acceptance, and meeting federal regulatory standards. Meeting these criteria requires technical and socio-economic analyses in conjunction with public input. Planners may also recognize that political acceptance requires compensation for the host community, either in the form of monetary or in-kind transfers. Following Breffle and Rowe [Breffle, W.S., Rowe. R.D., 2002. Comparing choice question formats for evaluating natural resource tradeoffs. Land Econ. 78 (2), 298–314], we use a “resource-to-resource” paired-comparison survey method to estimate compensatory values associated with an in-county landfill for both the host and non-host communities. Our results indicate that while a host-community household's minimum willingness to accept payment for hosting a landfill may exceed a non-host-community household's maximum willingness to pay, a large difference in population sizes between the two communities enables the landfill to pass a Kaldor potential compensation test.     

Religion,administration & public goods: Experimental evidence from Russia

In this paper, I argue that religion matters for the provision of public goods. I identify three normative foundations of Eastern Orthodox monasticism with strong economic implications: 1. solidarity, 2. obedience, and 3. universal discipline. I propose a public goods game with a three-tier hierarchy, where these norms are modeled as treatments. Obedience and universal discipline facilitate the provision of threshold public goods in equilibrium, whereas solidarity does not. Empirical evidence is drawn from public goods experiments run with regional bureaucrats in Tomsk and Novosibirsk, Russia. The introduction of the same three norms as experimental treatments produces different results. I find that only universal discipline leads to the provision of threshold public goods, whereas solidarity and obedience do not. Unlike in Protestant societies, in Eastern Orthodox societies free-riding occurs at lower than at higher hierarchical levels. Successful economic reforms in Eastern Orthodox countries start with the restructuring of the middle- and lower-ranked public sector. Authoritarian persistence is defined by the commitment of the dictator to overprovide public goods.     

Valuing changes in forest biodiversity

The paper attempts to improve current understanding of the economic value of biodiversity. Instead of the prevailing approach of using only one indicator of biodiversity (typically, species richness) we provide evidence that it is possible to value changes in a number of attributes which describe complex characteristics of biodiversity, based on ecological knowledge. The attributes used include structural, species and functional diversity. The empirical application is a choice experiment study conducted in the Białowieża Forest, Poland: our study is therefore also one of the first to cast light on the value of biodiversity protection in Eastern Europe. Interestingly, respondents valued passive protection regimes resulting in preservation of natural ecological processes. In addition, the respondents seemed to be concerned with the means, and not only the results of protection programmes.     

A Meta-analysis of Hypothetical Bias in Stated Preference Valuation

Individuals are widely believed to overstate their economic valuation of a good by a factor of two or three. This paper reports the results of a meta-analysis of hypothetical bias in 28 stated preference valuation studies that report monetary willingness-to-pay and used the same mechanism for eliciting both hypothetical and actual values. The papers generated 83 observations with a median ratio of hypothetical to actual value of only 1.35, and the distribution has severe positive skewness. We find that a choice-based elicitation mechanism is important in reducing bias. We provide some evidence that the use of student subjects may be a source of bias, but since this variable is highly correlated with group experimental settings, firm conclusions cannot be drawn. There is some weak evidence that bias increases when public goods are being valued, and that some calibration methods may be effective at reducing bias. However, results are quite sensitive to model specification, which will remain a problem until a comprehensive theory of hypothetical bias is developed.JEL classifications: C9, H41, Q26, Q28     

On the Behavioral Foundations of the Law of Supply and Demand: Human Convergence and Robot Randomness

This research builds on the work of D.K. Gode and Shyam Sunder who demonstrated the existence of a strong relationship between market institutions and the ability of markets to seek equilibrium—even when the agents themselves have limited intelligence and behave with substantial randomness. The question posed is whether or not market institutions account for the operation of the law of supply and demand in markets populated by humans with no role required of human rationality. Are institutions responsible for the operations of the law of supply and demand or are behavioral principles also at work? Experiments with humans and simulations with robots both conducted in conditions in which major institutional and structural aids to convergence were removed, produced clear answers. Human markets converge, while robot markets do not. The structural and institutional features certainly facilitate convergence under conditions of substantial irrationality, but they are not necessary for convergence in markets in which agents have the rationality of humans.     

Letter from the Editors

The authors explore academic misconduct in various forms and consider the role of student perceptions. They gather data from students in introductory economics courses regarding 31 types of misconduct. They estimate the relevance of various determinants of misconduct, acknowledging that they may vary across misconduct type and that students' perceptions may influence their behavior. Their estimates reveal that although there are determinants that influence student behavior across misconduct type, some types of misconduct have a unique set of determinants. They find that a student's perception of what constitutes misconduct is an important component of this behavioral decision. These results imply that to reduce a particular type of cheating, one must consider its specific determinants and ensure that students believe that the act is misconduct. In addition, students must believe that the probability of being caught is high.
