A Decision Theoretic Model of Public Opinion: Guns, Butter, and European Common Defense

Why do individuals support the public policies they do? We argue that individuals can have quite sophisticated policy preferences and that not correctly modeling those preferences can lead to critically misspecified empirical models. To substantiate this position we derive and test a decision‐theoretic model that relies upon three critical assumptions: (1) policies affect the provision of multiple goods about which individuals care; (2) individuals have diminishing returns to scale in those goods; and (3) preferences over at least some subset of those goods are correlated. Using this model, we demonstrate that arbitrarily small secondary policy effects can confound predictions over primary policy effects. Thus, not considering even arbitrarily small policy effects can cause one to conclude that evidence is consistent with one's theory when in fact it is inconsistent or vice versa. Testing this theory on support for forming a European common defense, we find evidence consistent with our model.     

Should South Korea go Nuclear?

A nuclear debate has arisen in South Korea following North Korea's nuclear tests and weapons program. Despite the US extended nuclear deterrence for its security, a sizable section of the people in South Korea have started debating if their country can revisit the nuclear option as a deterrent to North Korea's continued threats. Several law makers have started articulating such a view. Several opinion polls held recently also endorse such a view. However, the US is unlikely to allow South Korea to take the nuclear path as it would have serious consequences not only for the region but also the world. China would also not rejoice with the prospect of having another nuclear power in its neighborhood. If South Korea goes nuclear, Japan and Taiwan will find it difficult to resist having their own nuclear weapons. To stem such a trend, it becomes all the more necessary for the international community to address the issue of denuclearizing North Korea. The suspended Six-Party-Talks ought to restart soon and China has a great role in reigning in Pyongyang. Fortunately, the government in South Korea has not supported the view of the country going nuclear. But if the security situation deteriorates further, it might become irresistible for the government to have a rethink, with an inevitable domino effect in Japan and Taiwan soon.

This article makes an in-depth study of the prevailing trend in South Korea, the views of some influential law makers pleading for the country to go nuclear, various public opinions polls, possible US stance and implications that such a change in policy would have on the region's security situation and the author's assessment based on the critical examination of the above-mentioned factors. Many sources have been cited to analyze this issue before arriving at an objective assessment of the point raised in this essay.     

The Displaying of Yard Signs as a Form of Political Participation

Despite the ubiquity of yard signs, little is known about how and why individuals display them. Using two original studies of the 2008 presidential race, along with American National Election Study data, we address three points pertaining to this understudied form of political participation. First, what are the correlates of the individuals and households that display signs? Second, what motivates such displays, and to what extent do those motives reflect expressive and communicative desires? Finally, how do individuals obtain signs, and do individuals—rather than parties or candidates—play a role in spreading signs throughout neighborhoods? Our findings suggest that the dissemination of yard signs is not merely a top–down process driven by campaign professionals, but a genuine participatory act that is fueled by individual initiative and social networking.
