EVIDENCE ON THE ACCURACY OF EXPENDITURES REPORTED IN RECREATIONAL SURVEYS

This article discusses the results of four experiments to test the accuracy of recreational expenditures reported in survey relative to expenditures reported in dairies. We found few situations in which the reported expenditures in the surveys and diaries differ significantly. In general, we conclude that individuals are able to accurately report recreational expenditures in ex post mail surveys. Given the wide usage of survey expenditure data by economists, we find this results encouraging.Resource /Energy Economics and Policy,

Everyday memory deficits associated with anabolic-androgenic steroid use in regular gymnasium users

Background: This study compared a group of 47 regular gym users who take androgenic-anabolic steroids (the AAS group) as part of their recreational sport, with a group of 48 regular gym users who do not use AAS (the Non-AAS group) on self-reports of Retrospective memory (RM), executive function (EF) and prospective memory (PM), which are all critical to everyday remembering. Methods: All participants were tested using an on-line Survey Monkey method. The Prospective and Retrospective Memory Questionnaire (PRMQ) assessed everyday RM and PM deficits and the Executive Function Questionnaire (EFQ) assessed self-reported problems in EF. A drug-use questionnaire and a mood questionnaire were also administered Results: After observing no between-group differences on alcohol or mood, omitting anyone who drank excessively or had drank recently, smoked or reported using any illegal drug, three one-way ANCOVAs (controlling for age) revealed that the ASS group reported significantly more RM deficits, EF deficits, and PM deficits, when compared with the NonASS group. Conclusion: It was concluded that AAS use in a recreational sports context is associated with RM, EF and PM deficits, indicating that AAS use may damage everyday remembering

A Comparison of Approaches to Mitigate Hypothetical Bias

We compare two approaches to mitigating hypothetical bias. The study design includes three treatments: an actual payment treatment, a contingent valuation (CV) treatment with a follow-up certainty question, and a CV treatment with a cheap talk script. Our results suggest that both the follow-up certainty treatment and the cheap talk treatment produce willingness-to-pay (WTP) estimates consistent with the actual payment treatment. However, the follow-up certainty treatment provides response distributions at all offer amounts that are statistically similar to the actual payment treatment, while the cheap talk treatment provides similar responses only at some offer amounts. Furthermore, the cheap talk treatment is effective only for inexperienced individuals. We conclude that the follow-up certainty approach is more consistent than the cheap talk approach for eliminating hypothetical bias.contingent valuation, hypothetical bias, follow-up certainty, cheap talk, nonmarket valuation, Environmental Economics and Policy, Public Economics, Research Methods/ Statistical Methods,

Accounting for Respondent Uncertainty to Improve Willingness-to-Pay Estimates

In this paper we develop an econometric model of willingness to pay that integrates data on respondent uncertainty regarding their own willingness to pay. The integration is utility consistent and does not involve calibrating the contingent responses to actual payment data, and so the approach can "stand alone". In an application to a valuation study related to whooping crane restoration, we find that this model generates a statistically lower expected WTP than the standard CV model. Moreover, the WTP function estimated with this model is not statistically different from that estimated using actual payment data, suggesting that when properly analyzed using data on respondent uncertainty, contingent valuation decisions can simulate actual payment decisions. This method allows for more reliable estimates of WTP that incorporates respondent uncertainty without the need for collecting comparable actual payment data.

Communist Involvement in the French Resistance

This presentation focuses on the memoir Outwitting the Gestapo by Lucie Aubrac in 1984 and translated in English in 1993. Aubrac was a communist-aligned individual in the French Resistance who fought against the German occupation. Outwitting the Gestapo written as her diary that is the account of her resistant activities from February 1943 til about February 1944. The important part of this account is her rescue of her husband and other resistance fighters from the Gestapo. Her husband was held captive by Klaus Barbie. Barbie was the head of the Gestapo in Lyons and is known infamously as the “Butcher of Lyons”. Aubrac successfully broke everyone out of prison, all the while being several months pregnant with their second child. This is connected to my project by showing firsthand how Communists were resisting and worked well with other groups

Lead Toxicity and Flint, Michigan

In light of the recent events in Flint, Michigan this poster will review lead poisoning and its long term effects. We will be covering the multitude of sources of lead poisoning, the mechanisms by which lead does its damage, detection methods, treatment options, and limitations therein. The issues in Flint have highlighted the flaws in current acceptable detection procedures as well as brought to light the dangers of lead. Public concerns about clean drinking water have brought these issues to the forefront
