I view polarization as the unifying theme between my study of political behavior and political institutions. The ideological extremity of the major political parties at the mass level determines the politicians we observe at the elite level. In turn, these politicians create more or less ideologically extreme laws, bounded by the desires of their constituents and the goals of their parties. These lawmaking strategies and resulting policy subsequently affect how likely individuals are to approve of elite institutions and the lawmakers who embody them. I pair this substantive interest with a broad one in political methodology.

Below are texts of virtually all of my publications (except books). You will also find data and replication material for any publication for which I am the first author. If you're interested in data and replication material for other publications, please contact my co-authors!

We introduce dynamac for R, a suite of commands designed to assist users in modeling and and visualizing the effects of ARDL models (through dynardl) and implement the bounds test for cointegration (through pssbounds). Please feel free to email me directly with bugs. Please see the Computing page for more information.

We pair data collected from Canadian newspapers with Markov-switching dynamic regression (MSDR) models to evaluate whether courts can help set the national policy agenda. (Presented at the The New World of Comparative Political Communication Conference in 2016.)

We present new measures of electoral polarization. We then evaluate the effect of presidents on polarization, both generally and within the individual parties, using Box-Tiao multiple impact assessments. We find presidents are central to polarization. (Presented at APSA in 2015.)

Wood, B. Dan and Soren Jordan. 2017. Party Polarization in America: The War Over Two Social Contracts. Cambridge: Cambridge University Press. DOI: 10.1017/9781108164450.

We generate novel empirical data on the nature of ideology in the public, paired with detailed historical accounts of party conflict (largely the work of B. Dan Wood), to illustrate the historical nature of polarization and its fundamental ties to economic policy. (Portions presented at MPSA in 2012 and APSA in 2011 and 2015.)

We pair the Partisan Polarization and Issue Complexity theory of representation with the evolving polarization of issues to predict changes in issue representation over time.

Jordan, Soren and Grant Ferguson. 2016. ``Extremism in Survey Measures of Ideology.'' Research & Politics 3 (3): DOI: 10.1177/2053168016669743.

We use the 1989 ANES Pilot Study to evaluate the effects caused by anchoring the common ideology question with the word ``very'' versus ``extremely.'' We find that more individuals indicate a strong ideology when asked if they are ``very'' versus ``extremely'' ideological, but these same respondents do not have strong ideological policy preferences. This work has implications for measuring polarization using general ideology. (Presented at SPSA in 2012.)

We present an axiomatic theory to account for when different models of dyadic representation (delegate, trustee, responsible party, and so on) arise—along with abundant verification tests of the theory. (Portions presented at MPSA in 2013, APSA in 2011, and SPSA in 2011.)

This project uses basic tools of cluster analysis along with qualitative coding of the polarizing words in the party platforms to accomplish two goals: understanding the timeline of elite polarization and the dimensions on which the parties have polarized. (Presented at MPSA in 2013.)
