We design two institutions that collect individual contributions to provide multiple public good units, inspired by a problem to deliver ecosystem services as a step-level public good (delivered in discrete increments). We set up a public good experiment wherein either all individuals for one group and are responsible for providing the two units (aggregated-group approach), or two groups provide one unit separately, but both group benefits if any unit is provided (disaggregated-group approach). Our interest is to test which of these two institutions performs “better” through the collective decision process. Our results show that, in general, the aggregated-group has a higher rate of success delivering at least one unit of the public good, while the...

What do people bring into the game : experiments in the field about cooperation in the commons

Cardenas, Juan-Camilo; Ostrom, Elinor.

The study of collective action requires an understanding of the individual incentives and of the institutional constraints that guide people in making choices about cooperating or defecting on the group facing the dilemma. The use of local ecosystems by groups of individuals is just one example where individual extraction increases well-being, but aggregate extraction decreases it. The use of economic experiments has enhanced the already diverse knowledge from theoretical and field sources of when and how groups can solve the problem through self-governing mechanisms. These studies have identified several factors that promote and limit collective action, associated with the nature of the production system that allows groups to benefit from a joint-access...

Closing down the Farm: An Experimental Analysis of Disinvestment Timing

Maart, Syster Christin; Musshoff, Oliver; Odening, Martin; Schade, Christian.

Agrarian structures are often characterized by some kind of economic inertia. It is particularly puzzling why unprofitable farms persist over time instead of being sold. In this paper we analyze the exit decision of farmers using the real options approach. The validity of the real options theory is assessed by means of laboratory experiments. Our results show that real options models are able to predict actual disinvestment decisions better than traditional investment theory. Nevertheless, the observed disinvestment reluctance was even more pronounced as predicted by theory. This finding suggests the inclusion of bounded rationality into normative disinvestment models.

Potential poverty traps among the rural poor suggest a need to reduce poor farmers' vulnerability by stabilizing crop yields and limiting yield losses. Advances in agricultural biotechnology enable breeders to address this need more directly than ever before with crops that reduce production risk by tolerating climate fluctuation or resisting biotic stresses. Will poor farmers who could benefit most from less vulnerability choose to purchase such risk-reducing seeds? I use data from a household survey and experiment involving farmers in India to infer their valuation of changes in the mean, variance, and skewness of yield distributions. I conclude that these farmers value increases in expected yield in the yield distribution but seem indifferent about...

Experimental Economics methods are used to determine Hispanic consumers’ sensory acceptance of pasture-fed beef and evaluate visual and taste influences on their overall preferences and willingness-to-pay (WTP). Two hundred and thirty-one Hispanic consumers in four experimental sites in Virginia participated in a laboratory experimental procedure where they visually examined and tasted pasture-fed and conventionally produced grain-fed beef, and then participated in a non-hypothetical Multiple Price Lists (MPL) experiment to determine their WTP. Hispanic consumers perceived significant differences between pasture-fed and grain-fed beef’s appearance and taste. Visual and taste acceptances are closely correlated to and significantly influence overall...

We evaluate the effectiveness of non optimal and temporally inconsistent incentive policies for regulating the exploitation of a renewable common-pool resource. The corresponding game is an N-person discrete-time deterministic dynamic game of T periods fixed duration. Three policy instruments with parameters that remain constant for the whole horizon are evaluated: a pigouvian tax (flat tax), an ambient tax (ambient flat tax) and an instrument combining the two previous ones (mixed flat instrument). We test in the lab the predictions of the model solved for 3 distinct behavioural assumptions: (a) sub-game perfection, (b) myopic behaviour, and (c) joint payoff maximization. We find that subjects behave myopically in the unregulated situation, which agrees...

In this research, we integrated an experimental auction with sensory science techniques—namely, trained sensory panels used to analyze the sensory attributes of wines—to examine the effects of objective and sensory information in the market for California-produced Cabernet Sauvignons. The experiment permitted observation of consumer valuation for sensory attributes of wine, appellations, expert ratings, and wineries. Participants submitted bids each time they received new information about the wines. The balanced experimental design permits evaluation of the effects of consumer characteristics on attribute valuation. We had 236 people participate in the research, which consisted of nine rounds of bidding and one round of hedonic liking scores. Rounds...

Tradable emissions permits have been implemented to control pollution levels in various markets around the world and represent a major component of legislative efforts to control greenhouse gas (GHG) emissions in the United States. Because permits are supplied for a fixed level of pollution, allowing the market for permits to determine the price, there is a desire for price control mechanisms which would protect firms otherwise susceptible to price spikes caused by fluctuations in the demand for pollution abatement. We test permit markets in an experimental laboratory setting to determine the effectiveness of several price control mechanisms. Evidence suggests that both permit supply adjustments and traditional price ceilings (hard ceilings) effectively...

Using Experimental Economics to Measure the Role of Parental Generosity and Food Control in Childhood Obesity

Ehmke, Mariah D.; Morgan, Kari; Schroeter, Christiane; Larson-Meyer, Enette; Ballenger, Nicole.

This research uses experimental economics to measure the effect of parental generosity and child response on childhood overweight and obesity. The 'Carrot-Stick' experiment, an adaptation of the standard dictator game in which the respondent (the child) can punish or reward the dictator (the parent) based on the dictator's generosity, served as basis of our examination. Two treatments are conducted, in which the child spends his or her earnings on non-food and food items. Our empirical analysis shows significant relationships between parental weight and their level of generosity regarding food items. We conclude that child response behavior, obesigenic factors in the household, and the child's tendency toward being overweight and obese are significantly...

Disinvestment, in the sense of project termination and liquidation of assets including the cession of a venture, is an important realm of entrepreneurial decision-making. This study presents the results of an experimental investigation modeling the choice to disinvest as a dynamic problem of optimal stopping in which the patterns of decisions are analyzed with entrepreneurs and non-entrepreneurs. Our experimental results reject the standard net present value approach as an account of observed behavior. Instead, most individuals seem to understand the value of waiting. Their choices are weakly related to the disinvestment triggers derived from a formal optimal stopping benchmark consistent with real options reasoning. We also observe a pronounced...

Economies of scale and scope are often not exploited in Western agriculture. A general reason is probably that various types of transaction costs limit coordination among farmers. A more specific explanation is that coordination on land markets or machinery cooperation is difficult to achieve when farmers are heterogeneous as some kind of price differentiation is necessary for a Pareto-superior solution. This paper investigates experimentally such a coordination game with heterogeneous agents using an example inspired by agricultural land markets. The experimental findings suggest that a Pareto-optimal solution may not be found when agents are heterogeneous. The findings provide evidence for market failures and cooperation deficits as reasons for...

We investigate the strategic decision behavior of female entrepreneurs in a realistic market entry experiment where individuals started with gains or losses experienced prior to the game. We compare the entry behavior of female entrepreneurs to the entry behavior of male entrepreneurs and to the entry behavior of female and male students. We find that female entrepreneurs show entry patterns very similar to that of male entrepreneurs and very different from female students: female entrepreneurs on average over enter markets and do not react to their opponents’ prior experiences much. The same accounts for male entrepreneurs. Furthermore, we find that entrepreneurs in general exhibit significantly higher mean entry probabilities than students, whereby...
