the informational content of prices when Policy Makers react to financial markets
Journal of Economic Theory, 2019Co-Authors: Christoph SiemrothAbstract:Abstract When can Policy Makers use Policy-relevant information from financial market prices and how does Policy affect price informativeness? I analyze a novel setting with noise where a Policy Maker tries to infer information about a state variable from prices to improve Policy decisions, and Policy in turn affects asset values. I derive a necessary and sufficient condition for the possibility of information revelation in equilibrium, which might not be possible if the Policy reaction to prices punishes traders for revealing their information. If the Policy Maker is uninformed, then Policy objectives do not change price informativeness, but they do if the Policy Maker has independent information about the state. I also analyze Policy Maker transparency, and find that Policy Makers with objectives having a large impact on asset values should publish their information before trading to make prices more informative. In other cases, intransparency can be optimal.

the informational content of prices when Policy Makers react to financial markets
Social Science Research Network, 2015Co-Authors: Christoph SiemrothAbstract:I analyze settings where a Policy Maker needs information that financial market traders have in order to implement her optimal Policy, and market prices may reveal this information. Policy decisions, in turn, affect asset values, possibly punishing the informed for trading on information. Applications include central bank Policy reactions to asset prices or regulator reactions to bond prices. In the first part without noise, I derive a necessary and sufficient condition for the possibility of fully revealing equilibria, which identifies all situations where learning from prices for Policy purposes works, and where it does not. Full revelation may be impossible because the pricing problem is a self-defeating prophecy, impairing incentives to trade on information. I demonstrate how the condition can be used for asset design that supports information revelation by markets. In the second part, I develop a noisy model of trader-Policy Maker interaction. Noise can solve the problem of self-defeating prophecies in specific situations, but in general it may still occur. Using a novel solution approach, I derive a necessary and sufficient condition for the existence of revealing equilibria in a general class of noisy equilibria that allows for nonlinear price and Policy functions.

obesity prevention programs and policies practitioner and Policy Maker perceptions of feasibility and effectiveness
Obesity, 2013Co-Authors: Verity Cleland, Briohny Mcneilly, David Crawford, Kylie BallAbstract:Objectives The aims of this study were to map obesity prevention activity being implemented by government, non-government, and community-based organizations; to determine practitioner and Policy-Maker perceptions of the feasibility and effectiveness of a range of evidence-based obesity prevention strategies; and to determine practitioner and Policy-Maker perceptions of preferred settings for obesity prevention strategies. Design and Methods This study involved a cross-sectional survey of 304 public health practitioners and Policy-Makers from government, non-government, and community organizations across Victoria, Australia. Participants reported their organizations' current obesity prevention programs and policies, their own perceptions of the feasibility and effectiveness of strategies to prevent obesity and their preferred settings for obesity prevention. Results Thirty-nine percent had an obesity prevention Policy, and 92% were implementing obesity prevention programs. The most common programs focused on education, skill-building, and increasing access to healthy eating/physical activity opportunities. School curriculum-based initiatives, social support for physical activity, and family-based programs were considered the most effective strategies, whereas curriculum-based initiatives, active after-school programs, and providing access to and information about physical activity facilities were deemed the most feasible strategies. Schools were generally perceived as the most preferred setting for obesity prevention. Conclusion Many organizations had obesity prevention programs, but far fewer had obesity prevention policies. Current strategies and those considered feasible and effective are often mismatched with the empirical literature. Systems to ensure better alignment between researchers, practitioners, and Policy-Makers, and identifying effective methods of translating empirical evidence into practice and Policy are required.

198 Policy Maker s perceptions of the role of research in injury prevention legislation
Injury Prevention, 2016Co-Authors: Alison Macpherson, Linda Rothman, Pamela Fuselli, Kathy Belton, Lise Olsen, Ian PikeAbstract:Background Injury prevention Policy is crucial for the safety of Canada’s children; however, legislation is not adopted uniformly across the country. Researchers and Policy Makers must work together to develop effective legislation that is evidence-based but little is known regarding Policy Makers views regarding the importance of research in facilitating the legislative process. Methods Purposive snowball sampling identified individuals involved in injury prevention practice and Policy throughout Canada. In an online survey, respondents identified injury topics relevant to them and rated the importance of enablers to injury legislation using a 5 point Likert scale. Results There were 57 respondents with representation from all 10 provinces. The most common topics were, bicycle helmets (77%), cell phone-distracted driving (63%), booster seats (49%), ski helmets (42%), and graduated driver’s licensing (37%). The most frequently identified enabler was that research/surveillance was readily available (59%). Other commonly reported research enablers were: research of sufficient quality/quantity that was easy to understand and in a useful format and affiliation of researchers with reputable organisations. Less important was researchers having similar priorities as Policy Makers and understanding the Policy process. The importance of different research enablers varied by injury topic. Conclusions Although Policy Makers identified the importance that injury prevention research was readily available, it appeared to be less important that researchers had similar priorities or understood the Policy process, with variability by topic. This presents a challenge for researchers to conduct timely research and emphasises the need for ongoing relationships with Policy Makers with discussions early in the research process. This would facilitate the development of common injury prevention priorities to ensure research is used effectively in the legislative process.
