We observe a positive effect on the speech differences between the government and the opposition, suggesting that broadcasting question hours can exacerbate language use. However, we do not observe that the broadcasts of question hours would affect left-right polarization. (5/8)

Polarization is estimated separately for the treated question hours and for the other sessions. Thus, we can estimate the effects of broadcasting on speech polarization by comparing levels in these different groups before and after the start of broadcasting. (4/8)

We measure speech differences (speech polarization) between different groups using a method developed by Gentzkow, Shapiro & Taddy (2019), that is, how easy it is to identify speaker type by their speech alone. (3/8)

The design is based on the 1989 introduction of TV broadcasting during the first question hour of every month, while other question hours were not televised until 2007. This facilitates difference-in-differences analysis. (2/8)

New research on the dynamics between media and politicians' behavior! In our article (together with @jerniemin and @sallanen), we study the impact of televising parliamentary question hours on politicians' behavior in Finland. Paper: onlinelibrary.wiley.com/doi/10.1111/... (1/8)
