1. Renewable Energy - Federal Funding Ari Ziemer Aleksandra Galaszewicz Ariel Zynger Ignacio Marziani Guidone

2. Survey Questions Should the Federal government increase funding for research on renewable energy by $500 billion? Yes or No Should the Federal government shift funding from other areas to increase funding for research on renewable energy by $500 billion? Yes or No Should the Federal government raise tax revenue by $500 billion taxes to increase funding for research on renewable energy? Yes or No Should the Federal government increase the deficit by $500 billion to increase funding for research on renewable energy? Yes or No

3. DV & Key Hypotheses Dependent variable: Positive, or “Yes”, responses Hypotheses: The ‘shift funding’ and ‘increase funding’ framing effects should yield a higher % of ‘Yes’ responses Responses will not vary significantly by gender Democrats will favor ‘Yes’ responses in larger proportion than Republicans A higher level of education should correlate with a higher % of ‘Yes’ responses

4. Main Data and Key Insights Framing effect # of respondents ‘Yes’ response Increase funding 100 59% Increase deficit 100 56% Shift funding 94 64% Raise taxes 116 41% Insights/Observations ‘Increase funding’ framing effect integrates the other three. Falls in between ‘increase deficit’ and ‘shift funding’ ‘Raise taxes’ is the framing effect that results in the least % of adept individuals. In fact, there is a significant difference between this effect and the other three. ‘Shift funding’, on the contrary, results in the framing effect with the highest % of ‘Yes’ respondents Sample size is large enough to reduce random error considerably, as we will observe through some examples
