How Conditioning on Posttreatment Variables Can Ruin Your Experiment and What to Do about It

In principle, experiments offer a straightforward method for social scientists to accurately estimate causal effects. However, scholars often unwittingly distort treatment effect estimates by conditioning on variables that could be affected by their experimental manipulation. Typical examples include controlling for posttreatment variables in statistical models, eliminating observations based on posttreatment criteria, or subsetting the data based on posttreatment variables. Though these modeling choices are intended to address common problems encountered when conducting experiments, they can bias estimates of causal effects. Moreover, problems associated with conditioning on posttreatment variables remain largely unrecognized in the field, which we show frequently publishes experimental studies using these practices in our discipline's most prestigious journals. We demonstrate the severity of experimental posttreatment bias analytically and document the magnitude of the potential distortions it induces using visualizations and reanalyses of real‐world data. We conclude by providing applied researchers with recommendations for best practice.     

The Craft of Policy Design: Can It Be More Than Art?

The craft for predicting and evaluating the impacts of policy alternatives has received much of the attention of students of public policy analysis. Relatively little attention has been given to understanding and improving the craft for designing alternative policies. Beyond catalogs of generic policy instruments, two sources provide useful insights into policy design. First, the study of institutional choice as policy design draws attention to the selection of procedures and incentive systems to achieve substantive policy outcomes. Second, the study of the manipulation of the dimensions of policy choice (heresethetics), which provides insight into strategy in political arenas, may help with the broader problem of packaging and presenting policies so that they remain viable during implementation.     

Local Economic Development: What is Proposed, What is Done, and What Difference Does it Make?

This paper assesses the comparative policy insights gained from the articles in the symposium in terms of three dimensions: policies proposed, actions taken, and impacts scored. Local economic development interventions are classified in terms of a five-way categorization in terms of geographic breadth of action and reliance on complementary private action as a prerequisite to lasting impact. The nine symposium cases are then examined for their evidence on development efforts' accountability to the public and lessons about efficient use of public funds. The paper concludes that the cases demonstrate that most development efforts have wasted public funds, offering at best the limited success resulting from efforts to beggar neighboring local economics with which competition for development continues.     

Government as Catalyst: Can It Work Again with Wireless Internet Access?

As the Internet becomes an indispensable component of the global economy, Internet access is an increasingly important prerequisite to exploiting social, economic and educational opportunities. Municipal wireless networks (MWNs), which are wireless Internet access networks created with active local leadership and involvement, are seen as a potential solution. In this case study we describe the development of the Philadelphia MWN including goals, stakeholder expectations, policy, applications, technology, management models, funding, and implementation. The case provides insights on how communities can act as catalysts and use information technology to promote social and economic change. We found that MWNs involve competing private and public sector stakeholders, and it is important to clearly identify the main application of the MWN. We also found that focusing on the digital divide affords both opportunities and risks, and there are powerful external forces that impact MWNs and the underlying technology.     

Serbia After the Criminal Past: What Went Wrong and What Should be Done

This article explores the relationship between the recent criminalpast and the contemporary socio-political condition in Serbia.Basic assumptions employed are that the recent past is definedby collective crimes, this past has retained relevance afterthe regime change of October 2000 and that Serbia has thus farchosen the wrong methods for dealing with its criminal legacies.Due to the persistence of damaging political, cultural and moralattitudes about the past, the overthrow of Slobodan Milosevichas failed to bring about the necessary political and moralbreak. Thus, it is legitimate to explore alternative ways ofcoming to terms with the legacies of past crimes, including,as this article proposes, the establishment of a truth commissionin Serbia.     

The Federation — What Makes It Work and What Should We Be Thinking About for the Future

The Australian Federation is unique. Like all federations there is a division of powers between the various levels of government. However, unlike almost all other federations, the Australian Federation requires the cooperation of the states and the Commonwealth in order to achieve their institutional functions. This federal system can properly be described as 'cooperative federalism'. An understanding of the role of the states within this federal system suggests an urgent need for major constitutional reform at the state level.     

What Gets Measured,Gets Done: Understanding and Addressing Middle‐Class Challenges

Middle‐class families face a range of challenges, including uneven income growth, imposing child care costs, and affordability gaps for higher education. The ideal policies by which policy makers and public administrators can aid the middle class are far from obvious. Policy solutions are likely to mirror our government and population, meaning that they will be decentralized and varied. Achieving a “growing and thriving middle class” requires understanding the composition of the middle class across the country. Benchmarking and measuring the middle‐class condition at the state and substate levels is critical to crafting and adopting effective policy solutions. This Viewpoint essay highlights the Colorado context to demonstrate the measurement of the middle class and tracking of its lived experiences.     

Recognition and Social Justice: What Critical Theory Can Learn From Paid Domestic Laborers in the United States

Working in private homes, often isolated from the community and denied the legal rights and protections that most other workers enjoy, paid domestic laborers make up some of the most socially marginalized, vulnerable, and exploited workers in the United States today. This article explores the theoretical possibilities for an account of justice, based on the concept of recognition, to critique their work experiences, legal exclusion, and social status. To do so, it draws on the contrasting accounts of recognition advanced by Axel Honneth and Nancy Fraser, which focus on the psychological and the socio-structural dimensions of recognition respectively. While both theories generate compelling critiques of the conditions of domestic laborers, it is shown that neither one alone can capture the full range of injustices experienced, and that each can in fact complement the other. The article thus sketches an account of justice based on both the psychological and socio-structural dimensions of recognition.     

A Priori Voting Power: What Is It All About?

We explain the meaning of a priori voting power and outline how it is measured. We distinguish two intuitive notions as to what voting power means, leading to two approaches to measuring it. One conception, I-power, focuses on a voter's potential influence over the outcome of decisions by a voting body. The second conception, P-power, focuses on voters' payoff, their expected share of a fixed winning 'prize'. We discuss and rebut some philosophical and pragmatic objections, according to which a priori (as distinct from actual) voting power is worthless or inapplicable.     

“Therefore,Get Wisdom”: What Should the President Know,and How Can He Know It?

The literature on the U.S. presidency offers analysis of how the presidential advice and information support function has been performed. Some studies go further to suggest certain principles for designing the advice- and information-giving process involved in presidential decision making, along with organizational features to implement such principles. A well-established principle, based on comparative case studies, is that presidents should institutionalize distrust. Implementation of this principle usually involves channeling competing options, along with supporting information, to the Oval Office before a president becomes committed to a course of action or policy choice. In designing how the presidential support function is to operate, the advantages and disadvantages of the institutionalized distrust principle should be carefully examined, taking into account circumstantial conditions. This article examines this practical issue from the perspective of a historically oriented presidency scholar, writing during the transition to the Barack Obama administration.
