Political stock markets (PSM) are sometimes seen as substitutes for opinion polls. On the bases of a behavioural model, specific preconditions were drawn out under which manipulation in PSM can weaken this argument. Evidence for manipulation is reported from the data of two separate PSM during the Berlin 1999 state elections.

Scholars disagree whether negative advertising demobilizes or stimulates the electorate. We use an experiment with over 10,200 eligible voters to evaluate the two leading hypotheses of negative political advertising. We extend the analysis to examine whether advertising differentially impacts the turnout of voter subpopulations depending on the advertisement's message. In the short term, we find no evidence that exposure to negative advertisements decreases turnout and little that suggests it increases turnout. Any effect appears to depend upon the message of the advertisement and the characteristics of the viewer. In the long term, we find little evidence that the information contained in the treatment groups' advertisements is sufficient to systematically alter turnout.

An important class of investment decisions is characterized by unrecoverable sunk costs, resolution of uncertainty through time, and the ability to invest in the future as an alternative to investing today. The options model provides guidance in such settings, including an investment decision rule called the "bad news principle": the downside investment state influences the investment decision whereas the upside investment state is ignored. This study takes a new approach to examining predictions of the options model by using the tools of experimental economics. Our evidence, which is drawn from student and professional trader subject pools, is broadly consonant with the options model.

Political campaigns currently make extensive use of direct mail, particularly in state and local races, yet its effects on voter behavior are not well understood. This essay presents the results of large-scale randomized field experiments conducted in Connecticut and New Jersey during state and municipal elections of 1999. Tens of thousands of registered voters were sent from zero to nine pieces of direct mail. The target populations included party registrants with a strong history of voter participation, independents, and a random subset of registered voters. Our results indicate partisan campaign mail does little to stimulate voter turnout and may even dampen it when the mail is negative in tone.

We experimentally investigate simultaneous decision-making in two contrasting environments: one that encourages competition (lottery contest) and one that encourages cooperation (public good game). We find that simultaneous participation in the public good game affects behavior in the contest, decreasing sub-optimal overbidding. Contributions to the public good are not affected by participation in the contest. The direction of behavioral spillover is explained by differences in strategic uncertainty and path-dependence across games. Our design allows us to compare preferences for cooperation and competition. We find that in early periods, there is a negative correlation between decisions in competitive and in cooperative environments.

We present a field experiment to assess the effect of own and peer wage variations on actual work effort of employees with hourly wages. Work effort neither reacts to an increase of the own wage, nor to a positive or negative peer comparison. This result seems at odds with numerous laboratory experiments that show a clear own wage sensitivity on effort. In an additional real-effort laboratory experiment we show that explicit cost and surplus information that enables to exactly calculate employer's surplus from the work contract is a crucial pre-requisite for a positive wage-effort relation. This demonstrates that employee's reciprocity requires a clear assessment of the surplus at stake.

Acts of dishonesty permeate life. Understanding their origins, and what mechanisms help to attenuate such acts is an underexplored area of research. This study takes an economics approach to explore the propensity of individuals to act dishonestly across different contexts. We conduct an experiment that includes both parents and their young children as subjects, exploring the roles of moral cost and scrutiny on dishonest behavior. We find that the highest level of dishonesty occurs in settings where the parent acts alone and the dishonest act benefits the child. In this spirit, there is also an interesting, quite different, effect of children on parents' behavior: parents act more honestly under the scrutiny of daughters than under the scrutiny of sons. This finding sheds new light on the origins of the widely documented gender differences in cheating behavior observed among adults, where a typical result is that females are more honest than males.

Empirical tests of the relationship between international competitiveness and the severity of environmental regulations are hampered by the lack of pollution abatement cost data for non-U.S. countries. The theory of the firm suggests that environmental stringency can be measured by the difference between a polluting input's shadow price and its market price. We make a first attempt at quantifying such a measure for two industries located in nine European OECD countries. Overall, we provide (i) a new approach to measure cross-country regulatory differences in that we use a theoretically attractive measure of industry-specific private compliance cost, and (ii) empirical estimates that are an attractive tool for researchers and policymakers who are interested in examining how economic activity is influenced by compliance costs.

An information campaign that provided Kenyan teenagers in randomly selected schools with the information that HIV prevalence was much higher among adult men and their partners than among teenage boys led to a 65% decrease in the incidence of pregnancies by adult partners among teenage girls in the treatment group relative to the comparison. This suggests a large reduction in the incidence of unprotected cross-generational sex. The information campaign did not increase pregnancies among teenage couples. These results suggest that the behavioral choices of teenagers are responsive to information on the relative risks of different varieties of a risky activity. Policies that focus only on the elimination of a risky activity and do not address risk reduction strategies may be ignoring a margin on which they can have substantial impact.

We experimentally investigate the difference in competitiveness of 3-5 year-old boys and girls in the U.S. 123 children from a preschool are randomly matched into girl-girl, boy-boy, and boy-girl pairs of similar age and participate in a gender-neutral, competitive classroom activity using candy as an incentive. Children participate in a piece rate incentive scheme and a tournament incentive scheme in rounds 1 and 2, and select their preferred incentive scheme for round 3. We find that girls and boys choose to compete at equal rates - with 80% of children choosing to compete overall. We also find that girls' output in the task is significantly lower than that of boys under the tournament scheme, but not different in round 3 for the girls and boys who self-select into the tournament. All children display a remarkable rate of confidence - 84% of children believe they won under the tournament scheme. The gender of the match does not play a significant role.

This paper pits neoclassical theory against prospect theory by investigating several clean tests of the competing hypotheses. Consistent with previous work, the field experimental data suggest that prospect theory adequately organizes behavior among inexperienced consumers, whereas consumers with intense market experience behave largely in accordance with neoclassical predictions. The data indicate that the convergence in values occurs entirely because of lower Hicksian equivalent surplus values.

Direct mail fundraisers commonly provide a set of suggested donation amounts to potential donors, in addition to the option of writing in an amount. Yet little systematic evidence exists about the causal effects of suggested donation amounts on giving behavior. To this end, we conducted a field experiment on a direct mail solicitation to nearly 15,000 members of three public broadcasting stations. We varied (1) the vector of suggested amounts, and (2) whether the suggested amounts were fixed or varied as a proportion of the individual's previous donation. We find that increasing the vector of suggested amounts by about 20 percent statistically significantly reduces the overall probability of giving by about 15 percent. The overall impact on revenue is less clear, but appears to be somewhat negative. Higher suggested amounts also lead to write in amounts representing a greater proportion of donations. We attribute our result to the apparent cognitive cost of writing in a preferred amount that differs from a suggested amount. A second field experiment, in which we alter only one of the suggested amounts, gives evidence consistent with that theory and with the idea that donors prefer to give round numbers, as we see donors significantly more likely to give amounts of $90 or higher when suggested $100 versus $95.

Several experimental studies have recently provided strong evidence that the basic independence assumption, which is used in most theoretical and applied economic models to assess the operation of markets, is rarely appropriate. These results, which clearly contradict closely held economic doctrines, have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory. This paper refutes the generality of these experimental findings by going to a well-functioning marketplace and examining more than 350 individual decisions across various incentive compatible elicitation mechanisms. The data suggest that individuals with significant marketlike experience behave largely in accordance with neoclassical predictions: any observed WTA/WTP disparity amongst this group can be explained by neoclassical arguments. In light of these findings, I believe that we have discarded neoclassical explanations of the value disparity too quickly. More narrowly, these empirical results have important implications for stated valuation methods, such as contingent valuation.

In the rural areas of developing countries, teacher absence is a widespread problem. This paper tests whether a simple incentive program based on teacher presence can reduce teacher absence, and whether it has the potential to lead to more teaching activities and better learning. In 60 informal one-teacher schools in rural India, randomly chosen out of 120 (the treatment schools), a financial incentive program was initiated to reduce absenteeism. Teachers were given a camera with a tamper-proof date and time function, along with instructions to have one of the children photograph the teacher and other students at the beginning and end of the school day. The time and date stamps on the photographs were used to track teacher attendance. A teacher's salary was a direct function of his attendance. The remaining 60 schools served as comparison schools. The introduction of the program resulted in an immediate decline in teacher absence. The absence rate (measured using unannounced visits both in treatment and comparison schools) changed from an average of 42 percent in the comparison schools to 22 percent in the treatment schools. When the schools were open, teachers were as likely to be teaching in both types of schools, and the number of students present was roughly the same. The program positively affected child achievement levels: a year after the start of the program, test scores in program schools were 0.17 standard deviations higher than in the comparison schools and children were 40 percent more likely to be admitted into regular schools.

Walrasian tatonnement has been a fundamental assumption in economics ever since Walras' general equilibrium theory was introduced in 1874. Nearly a century after its introduction, Vernon Smith relaxed the Walrasian tatonnement assumption by showing that neoclassical competitive market theory explains the equilibrating forces in "double-auction" markets. I make a next step in this evolution by exploring the predictive power of neoclassical theory in decentralized naturally occurring markets. Using data gathered from two distinct markets- the sports card and collector pin markets-I find a tendency for exchange prices to approach the neoclassical competitive model prediction after a few market periods.

If we are to examine the role of "controls" in different experimental settings, it is appropriate that the word be defined carefully. The Oxford English Dictionary (Second Edition) defines the verb "control" in the following manner: "To exercise restraint or direction upon the free action of; to hold sway over, exercise power or authority over; to dominate, command." So the word means something more active and interventionist than is suggested by it's colloquial clinical usage. Control can include such mundane things as ensuring sterile equipment in a chemistry lab, to restrain the free flow of germs and unwanted particles that might contaminate some test.

We present results from a field experiment testing the gift-exchange hypothesis inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attribuable to past planting productivity. We compare planter productivity - the number of trees planted per day - on the day the gift was handed out with productivity on previous and subsequent days of planting on the same block, and thus under similar planting conditions. We find direct evidence that the gift had a significant and positive effect on daily planter productivity, controlling for planter-fixed effects, weather conditions and other random daily shocks. Moreover, reciprocity is the strongest when the relationship between planters and the firm is long term.
