We investigate judgment aggregation by assuming that some formulas of the agenda are singled out as premisses, and the Independence condition (formula-wise aggregation) holds for them, though perhaps not for others. Whether premiss-based aggregation thus de…ned is non-degenerate depends on how premisses are logically connected, both among themselves and with other formulas. We identify necessar...

Judgment aggregation theory investigates which procedures a group could or should use to form collective judgments (‘yes’ or ‘no’) on a given set of propositions or issues, based on the judgments of the group members. How, for instance, should the citizens of a state reach collective judgments on the three propositions that multiculturalism is desirable, that immigration should be promoted, and...

We investigate judgment aggregation by assuming that some formulas of the agenda are singled out as premisses, and the Independence condition (formula-wise aggregation) holds for them, though perhaps not for others. Whether premiss-based aggregation thus defined is non-degenerate depends on how premisses are logically connected, both among themselves and with other formulas. We identify necessa...

The aggregation of individual judgments over interrelated propositions is a newly arising …eld of social choice theory. I introduce several independence conditions on judgment aggregation rules, each of which protects against a speci…c type of manipulation by agenda setters or voters. I derive impossibility theorems whereby these independence conditions are incompatible with certain minimal req...

We propose a system for flexibly judging the misusage of honorifics in Japanese sentence. The system can point out misused words and phrases, and can also indicate how they are misused. The system uses judgment rules whose degrees of validity in modern Japanese society are quantified by psychological experiments. The system can judge sentences flexibly based on the learner's linguistic level by...

Several recent articles have defined and studied judgment aggregation rules based on some minimization principle. Although some of them are defined by analogy with some voting rules, the exact connection between these rules and voting rules is not always obvious. We explore these connections and show how several well-known voting rules such as the top cycle, Copeland, maximin, Slater or ranked ...

This paper examines the predictive power of weather for electricity prices in dayahead markets in real time. We find that next-day weather forecasts improve the forecast accuracy of Scandinavian day-ahead electricity prices substantially in terms of point forecasts, suggesting that weather forecasts can price the weather premium. This improvement strengthens the confidence in the forecasting mo...

I propose a new axiom on the aggregation of individual yes/no judgments on propositions into collective judgments: each collective judgment depends only on people’s judgments on relevant propositions. This contrasts with classical independence: each collective judgment depends only on people’s judgments on the current proposition. I generalize the premise-based and sequential-priority rules to ...

We compared auditory change detection to visual change detection using closely matched stimuli and tasks in the two modalities. On each trial, participants were presented with a test stimulus consisting of ten elements: pure tones with various frequencies for audition, or dots with various spatial positions for vision. The test stimulus was preceded or followed by a probe stimulus consisting of...
