  • Mostly haunted

    Open Access•Tom S Clark, Tom Clark et al.•ARTICLE•Tourism Recreation Research•2026•References: 51

    There is now a well-established literature on ghost tourism. However, much of this work examines aspects associated with the demand side of the industry, or the motivations and experiences of consumers. There are currently no studies that have sought to explore the supply of ghost tourism and the spatial, social, and economic relationships that exist between these places. Using Lower Tier Local Authorities (LTLAs) in England and Wales as the unit…

  • Minority will? A model of influential dissenting opinions

    Open Access•Sam England, Tom S Clark•ARTICLE•Journal of Theoretical Politics•2026•References: 42

    We study the incentives for writing dissenting opinions that try to shape the law. We model the interaction between a minority and majority in a collegial court setting. Dissenting judges calculate how much effort to put into a dissenting opinion with an expectation that their work can probabilistically affect how the law is applied in the future. That calculus can influence how a majority opinion author writes an opinion and the dynamics of coll…

  • Forced choice? Is bullying pushing non-binary students into cyber schools

    Dennis Beck, Robert Maranto et al.•ARTICLE•Educational Review•2024

    Little research addresses the schooling experiences of non-binary students; no prior work explores their experiences in cyber schools. Using unique data from a US multi-state cyber charter school, we compare the factors parents of non-binary students and parents of other students stated as reasons for leaving their prior schools to attend a cyber charter school in fall 2019 (before the COVID-19 pandemic). Despite a small sample size, we found sta…

  • Police Shooting Statistics and Public Support for Police Reforms

    Open Access•Kaylyn Jackson Schiff, Tom S Clark et al.•ARTICLE•Journal of Experimental Political…•2023•Cited by: 2•References: 18

    Does providing information about police shootings influence policing reform preferences? We conducted an online survey experiment in 2021 among approximately 2,600 residents of 10 large US cities. It incorporated original data we collected on police shootings of civilians. After respondents estimated the number of police shootings in their cities in 2020, we randomized subjects into three treatment groups and a control group. Treatments included …

  • Are Police Racially Biased in the Decision to Shoot

    Tom S Clark, Elisha Cohen et al.•ARTICLE•The Journal of Politics•2023•Cited by: 3•References: 63

    We present a theoretical model predicting that racially biased policing produces (1) more use of potentially lethal force by firearms against Black civilians than against White civilians and (2) lower fatality rates for Black civilians than White civilians. We empirically evaluate this second prediction with original officer-involved shooting data from 2010 to 2017 for eight local police jurisdictions, finding that Black fatality rates are signif…

  • Choosing cyber during Covid

    Open Access•Robert Maranto, Dennis Beck et al.•ARTICLE•Phi Delta Kappan•2021

    Substantial research has already examined how the COVID-19 pandemic has affected in-person schooling, but no prior work has explored its effects on cyber schools. Here, Robert Maranto, Dennis Beck, Tom Clark, Bich Tran, and Feng Liu compare the students entering a large national cyber charter school network in spring 2020, during the pandemic, with students entering in 2019 and 2018, before the pandemic. They find that the COVID cohort resembled …

  • Republican-Majority Appellate Panels Increase Execution Rates for Capital Defendants

    Deborah Beim, Tom S Clark et al.•ARTICLE•The Journal of Politics•2021•Cited by: 2•References: 11

    We use the quasi-random assignment of cases to three-judge panels on the US Courts of Appeals to assess the consistency of adjudication of death penalty appeals. We find clear evidence that panels apply different standards depending on whether a majority of the panel was appointed by Democratic or Republican presidents. Unlike previous work on panel effects in the US Courts of Appeals, we show that these effects persist to the end of the process …

  • Hard Times

    Tom S Clark, Tom Clark et al.•BOOK•Hard Times•2020

    An analysis of the enduring social costs of the post-2008 economic crisis 2008 was a watershed year for global finance. The banking system was eventually pulled back from the brink, but the world was saddled with the worst slump since the 1930s Depression, and millions were left unemployed. While numerous books have addressed the financial crisis, very little has been written about its social consequences. Journalist Tom Clark draws on the resear…

  • The Supreme Court

    Open Access•Tom S Clark•BOOK•Supreme Court•2019

    This book presents a quantitative history of constitutional law in the United States and brings together humanistic and social-scientific approaches to studying law. Using theoretical models of adjudication, Tom S. Clark presents a statistical model of law and uses the model to document the historical development of constitutional law. Using sophisticated statistical methods and historical analysis of court decisions, the author documents how soc…

  • Do Officer-Involved Shootings Reduce Citizen Contact with Government

    Elisha Cohen, A Gunderson et al.•ARTICLE•The Journal of Politics•2019•Cited by: 36•References: 40

    Police use of force bears on central matters of political science, including equality of citizen treatment by government. In light of recent high-profile officer-involved shootings (OIS) that resulted in civilian deaths, we assess whether, conditional on a shooting, a civilian's race predicts fatality during police-civilian interactions. We combine Los Angeles data on OIS with a novel research design to estimate the causal effects of fatal shooti…

  • Using Twitter to Study Public Discourse in the Wake of Judicial Decisions

    Open Access•Tom S Clark, Jeffrey K Staton et al.•ARTICLE•Journal of Law and Courts•2018•Cited by: 5•References: 33

    At the intersection of behavioral and institutional studies of policy making lie a series of questions about how elite choices affect mass public opinion. Scholars have considered how judicial decisions—especially US Supreme Court decisions—affect individuals’ support for specific policy positions. These studies yield a series of competing findings. Whereas past research uses opinion surveys to assess how individuals’ opinions are shaped, we beli…

  • Why Do Courts Delay

    Open Access•Deborah Beim, Tom S Clark et al.•ARTICLE•Journal of Law and Courts•2017•Cited by: 3•References: 26

    Answering one question often begets another. We present a decision-theoretic model that describes how this affects the sequencing of decisions over time. Because answering an easy question may raise a more difficult one, a rational judge may delay resolution even if he has perfect information about the correct decision. Furthermore, because otherwise unrelated questions may raise similar follow-ups, he may optimally clump decisions together. Our …

  • Precedent and Doctrine in a Complicated World

    Open Access•Steven Callander, Tom S Clark•ARTICLE•American Political Science Review•2017•Cited by: 12•References: 30

    Courts resolve individual disputes and create principles of law to justify their decisions and guide the resolution of future cases. Those tasks present informational challenges that affect the whole judicial process. Judges must simultaneously learn about (1) the particular facts and legal implications of any dispute; (2) discover the doctrine that appropriately resolves the dispute; and (3) attempt to articulate those rules in the context of a …

  • Estimating Vote-Specific Preferences from Roll-Call Data Using Conditional Autoregressive Priors

    Benjamin E Lauderdale, Tom S Clark•ARTICLE•The Journal of Politics•2016•Cited by: 3•References: 19

    Ideal point estimation in political science usually aims to reduce a matrix of votes to a small number of preference dimensions. We argue that taking a nonparametric perspective can yield measures that are more useful for some subsequent analyses. We propose a conditional autoregressive preference measurement model, which we use to generate case-specific preference estimates for US Supreme Court justices from 1946 to 2005. We show that the varyin…

  • Scope and precedent

    Open Access•Tom S Clark•ARTICLE•Journal of Theoretical Politics•2016•Cited by: 11•References: 31

    I develop a formal model of Supreme Court opinion-writing in an environment of uncertainty. In particular, the model captures how the Supreme Court will optimally design the specificity of its legal rules. The model focuses on the tradeoff between more precise rules which are controlling in a smaller subset of cases against less precise rules, which have wider applicability but yield less certain outcomes. When the basic model is considered in a …

  • Judicial Independence

    Open Access•Tom S Clark•OTHER•Emerging Trends in the Social and…•2015

    For analytic clarity, judicial independence is best thought of as a concept that captures a variety of features of a judicial system. One common, and useful, approach is to associate judicial independence with the ability of judges to, in practice, make decisions the outcomes of which are not dictated by extrajudicial pressures. In this spirit, research on judicial independence has examined a number of topics, two of which are (i) the origins and…

  • Measuring the Political Salience of Supreme Court Cases

    Open Access•Tom S Clark, Jeffrey R Lax et al.•ARTICLE•Journal of Law and Courts•2015•Cited by: 15•References: 23

    While Supreme Court cases are generally salient or important, some are many degrees more important than others. A wide range of theoretical and empirical work throughout the study of judicial politics implicates this varying salience. Some work considers salience a variable to be explained, perhaps with judicial behavior the explanatory factor. The currently dominant measure of salience is the existence of newspaper coverage of a decision, but de…

  • An Informational Model of Constitutional Jurisdiction

    Tom S Clark, Jeffrey K Staton•ARTICLE•The Journal of Politics•2015•References: 18

    In shaping constitutional courts' jurisdictions, societies must contend with the informational challenges associated with rule making and the distributive politics of granting courts jurisdiction over administrative lawmaking. Curiously, judges are often granted jurisdiction that seems to create a tension between their ability to acquire information about appropriate rules and to clearly articulate them. In particular, many courts handle the oner…

  • Should I Use Fixed or Random Effects

    Open Access•Tom S Clark, Drew A Linzer•ARTICLE•Political Science Research and…•2015•Cited by: 189•References: 14

    Empirical analyses in social science frequently confront quantitative data that are clustered or grouped. To account for group-level variation and improve model fit, researchers will commonly specify either a fixed- or random-effects model. But current advice on which approach should be preferred, and under what conditions, remains vague and sometimes contradictory. This study performs a series of Monte Carlo simulations to evaluate the total err…

  • Source Cues and Public Support for the Supreme Court

    Open Access•Tom S Clark, Jonathan P Kastellec•ARTICLE•American Politics Research•2015•Cited by: 33•References: 46

    It is well known that the public often relies on cues or heuristics when forming opinions. At the same time, leading theories of opinion formation about the Supreme Court see such support as relatively fixed. Using a series of survey experiments, we find source cues significantly influence the public’s support for the Court, including the extent to which individuals believe the Court should be independent from the elected branches. Specifically, …

  • Scaling Politically Meaningful Dimensions Using Texts and Votes

    Open Access•Benjamin E Lauderdale, Tom S Clark•ARTICLE•American Journal of Political…•2014•Cited by: 41•References: 28

    Item response theory models for roll‐call voting data provide political scientists with parsimonious descriptions of political actors' relative preferences. However, models using only voting data tend to obscure variation in preferences across different issues due to identification and labeling problems that arise in multidimensional scaling models. We propose a new approach to using sources of metadata about votes to estimate the degree to which…

  • Judicial Selection and Death Penalty Decisions

    Open Access•Brandice Canes-Wrone, Tom S Clark et al.•ARTICLE•American Political Science Review•2014•Cited by: 62•References: 41

    Most U.S. state supreme court justices face elections or reappointment by elected officials, and research suggests that judicial campaigns have come to resemble those for other offices. We develop predictions on how selection systems should affect judicial decisions and test these predictions on an extensive dataset of death penalty decisions by state courts of last resort. Specifically, the data include over 12,000 decisions on over 2000 capital…

    A major focus of judicial politics research has been the extent to which ideological divergence between the Court and Congress can explain variation in Supreme Court decision making.

    One-dimensional spatial models have come to inform much theorizing and research on the U.S. Supreme Court. However, we argue that judicial preferences vary considerably across areas of the law, and that limitations in our ability to measure those preferences have constrained the set of questions scholars pursue. We introduce a new approach, which makes use of information about substantive similarity among cases, to estimate judicial preferences t…

  • Rule Creation in a Political Hierarchy

    Open Access•Clifford J Carrubba, Tom S Clark•ARTICLE•American Political Science Review•2012•Cited by: 24•References: 24

    Principal-agent relations are replete in politics; politicians are agents of electorates, bureaucrats are agents of executives, lower courts are agents of upper courts, and much more. Commonly, principals are modeled as the rule-making body and agents as the rule-implementing body. However, principals often delegate the authority to make the rules themselves to their agents. The relationship between the lower federal courts and the Supreme Court …

  • The Genealogy of Law

    Open Access•Tom S Clark, Benjamin E Lauderdale•ARTICLE•Political Analysis•2012•Cited by: 21•References: 30

    Many theories of judicial politics have at their core the concepts of legal significance, doctrinal development and evolution, and the dynamics of precedent. Despite rigorous theoretical conceptualization, these concepts remain empirically elusive. We propose the use of a genealogical model (or “family tree”) to describe the Court's construction of precedent over time. We describe statistical assumptions that allow us to estimate this kind of str…

    We develop a model of opinion writing in the judicial hierarchy. The model adopts a case-space approach to judicial decision making with informational asymmetries across levels of the hierarchy. In the model, a lower court writes an opinion with two features: a legal rule and a level of quality. An upper court must then decide whether to review the decision. The model yields new insights about the strategic incentives created by the judicial hier…

  • Measuring Ideological Polarization on the United States Supreme Court

    The study of ideological polarization is an important topic in research ranging from behavioral-level to institutional studies of politics.

    We examine how the Supreme Court learns from lower court decisions to evaluate new legal issues. We present a theory of optimal stopping in which the Court learns from successive rulings on new issues by lower courts but incurs a cost when lower courts come into conflict with one another. The Court faces a strategic trade-off between allowing conflict to continue while it learns about a new legal issue and intervening to end a costly conflict bet…

In the model, a lower court writes an opinion with two features: a legal rule and a level of quality. An upper court must then decide whether to review the decision. The model yields new insights about the strategic incentives created by the judicial hier…

  • The Genealogy of Law

    Open Access•Tom S Clark, Benjamin E Lauderdale•ARTICLE•Political Analysis•2012•Cited by: 21•References: 30

    Many theories of judicial politics have at their core the concepts of legal significance, doctrinal development and evolution, and the dynamics of precedent. Despite rigorous theoretical conceptualization, these concepts remain empirically elusive. We propose the use of a genealogical model (or “family tree”) to describe the Court's construction of precedent over time. We describe statistical assumptions that allow us to estimate this kind of str…

  • The Supreme Court's Many Median Justices

    Open Access•Benjamin E Lauderdale, Tom S Clark•ARTICLE•American Political Science Review•2012•Cited by: 36•References: 28

    One-dimensional spatial models have come to inform much theorizing and research on the U.S. Supreme Court. However, we argue that judicial preferences vary considerably across areas of the law, and that limitations in our ability to measure those preferences have constrained the set of questions scholars pursue. We introduce a new approach, which makes use of information about substantive similarity among cases, to estimate judicial preferences t…

  • Rule Creation in a Political Hierarchy

    Open Access•Clifford J Carrubba, Tom S Clark•ARTICLE•American Political Science Review•2012•Cited by: 24•References: 24

    Principal-agent relations are replete in politics; politicians are agents of electorates, bureaucrats are agents of executives, lower courts are agents of upper courts, and much more. Commonly, principals are modeled as the rule-making body and agents as the rule-implementing body. However, principals often delegate the authority to make the rules themselves to their agents. The relationship between the lower federal courts and the Supreme Court …

  • The Supreme Court and Percolation in the Lower Courts

    Tom S Clark, Jonathan P Kastellec•ARTICLE•The Journal of Politics•2013•Cited by: 13•References: 22

    We examine how the Supreme Court learns from lower court decisions to evaluate new legal issues. We present a theory of optimal stopping in which the Court learns from successive rulings on new issues by lower courts but incurs a cost when lower courts come into conflict with one another. The Court faces a strategic trade-off between allowing conflict to continue while it learns about a new legal issue and intervening to end a costly conflict bet…

  • Scaling Politically Meaningful Dimensions Using Texts and Votes

    Open Access•Benjamin E Lauderdale, Tom S Clark•ARTICLE•American Journal of Political…•2014•Cited by: 41•References: 28

    Item response theory models for roll‐call voting data provide political scientists with parsimonious descriptions of political actors' relative preferences. However, models using only voting data tend to obscure variation in preferences across different issues due to identification and labeling problems that arise in multidimensional scaling models. We propose a new approach to using sources of metadata about votes to estimate the degree to which…

  • Judicial Selection and Death Penalty Decisions

    Open Access•Brandice Canes-Wrone, Tom S Clark et al.•ARTICLE•American Political Science Review•2014•Cited by: 62•References: 41

    Most U.S. state supreme court justices face elections or reappointment by elected officials, and research suggests that judicial campaigns have come to resemble those for other offices. We develop predictions on how selection systems should affect judicial decisions and test these predictions on an extensive dataset of death penalty decisions by state courts of last resort. Specifically, the data include over 12,000 decisions on over 2000 capital…

  • Judicial Independence

    Open Access•Tom S Clark•OTHER•Emerging Trends in the Social and…•2015

    For analytic clarity, judicial independence is best thought of as a concept that captures a variety of features of a judicial system. One common, and useful, approach is to associate judicial independence with the ability of judges to, in practice, make decisions the outcomes of which are not dictated by extrajudicial pressures. In this spirit, research on judicial independence has examined a number of topics, two of which are (i) the origins and…

  • Measuring the Political Salience of Supreme Court Cases

    Open Access•Tom S Clark, Jeffrey R Lax et al.•ARTICLE•Journal of Law and Courts•2015•Cited by: 15•References: 23

    While Supreme Court cases are generally salient or important, some are many degrees more important than others. A wide range of theoretical and empirical work throughout the study of judicial politics implicates this varying salience. Some work considers salience a variable to be explained, perhaps with judicial behavior the explanatory factor. The currently dominant measure of salience is the existence of newspaper coverage of a decision, but de…

  • An Informational Model of Constitutional Jurisdiction

    Tom S Clark, Jeffrey K Staton•ARTICLE•The Journal of Politics•2015•References: 18

    In shaping constitutional courts' jurisdictions, societies must contend with the informational challenges associated with rule making and the distributive politics of granting courts jurisdiction over administrative lawmaking. Curiously, judges are often granted jurisdiction that seems to create a tension between their ability to acquire information about appropriate rules and to clearly articulate them. In particular, many courts handle the oner…

  • Should I Use Fixed or Random Effects

    Open Access•Tom S Clark, Drew A Linzer•ARTICLE•Political Science Research and…•2015•Cited by: 189•References: 14

    Empirical analyses in social science frequently confront quantitative data that are clustered or grouped. To account for group-level variation and improve model fit, researchers will commonly specify either a fixed- or random-effects model. But current advice on which approach should be preferred, and under what conditions, remains vague and sometimes contradictory. This study performs a series of Monte Carlo simulations to evaluate the total err…

  • Source Cues and Public Support for the Supreme Court

    Open Access•Tom S Clark, Jonathan P Kastellec•ARTICLE•American Politics Research•2015•Cited by: 33•References: 46

    It is well known that the public often relies on cues or heuristics when forming opinions. At the same time, leading theories of opinion formation about the Supreme Court see such support as relatively fixed. Using a series of survey experiments, we find source cues significantly influence the public’s support for the Court, including the extent to which individuals believe the Court should be independent from the elected branches. Specifically, …
