¡Ú¥¿¥¤¥È¥ë¡ÛEstimating Japanese Parties Policy Position: Computer-Assisted Scaling of Legislative Speeches
¡Ú¾ì½ê¡Û1¹æ´Û401¶µ¼¼
¡Ú³µÍסÛ
This presentation is based on our ongoing research project which aims to estimate policy positions of Japanese political parties based on legislative speeches. We apply a computer-assisted scaling technique to tokenize the text into words and then to estimate party positions based on the data matrix of words and speakers. Estimated policy
positions can be used for a variety of empirical analyses and we present our analyses on the determinants of polarization of the Japanese parliament to illustrate its use. We will also show a comparison with other existing approaches of measuring party positions, namely the human-coded data of party manifestos (e.g. Comparative Manifestos Project) to validate the estimated party
positions obtained from legislative speeches.

*The talk will be given in English.
