At the Nexus of Observational and Experimental Research: Theory,Specification, and Analysis of Experiments with Heterogeneous Treatment Effects

Experimentalists are increasingly examining heterogeneous treatment effects, in which observed individual-level characteristics are hypothesized to moderate an experimental treatment effect. Such work places researchers at the nexus of experimental and observational approaches. In this paper, we discuss the theoretical and statistical issues that can arise in testing such hypotheses. We note that inclusion of an observed (as opposed to randomly-assigned) moderator introduces the possibility of confounds that are commonplace in observational data analysis but too-easily ignored in experimental data analysis. We simulate several different data generating processes that include heterogeneous treatment effects, and we discuss the implications of various statistical models. We aim to provide researchers who examine heterogeneous treatment effects with background and advice that enable them to identify where common issues may arise and to develop research designs and implement statistical tests that will mitigate them.     

Job Choice and Performance: Revisiting Core Assumptions about Public Service Motivation

Although there has been considerable enthusiasm for public service motivation (PSM) research in recent years, two of PSM's fundamental assumptions have been relatively untested: its impacts on job choice and on job performance. Using panel data from two different studies, we offer stronger observational tests of these core assumptions. The findings provide mixed evidence. When testing PSM's effect on employment choice, we find that PSM measured during a law student's first year predicts the sector in which they are employed after graduation three years later. In a separate study investigating PSM's effect on job performance, we find that government employee PSM does not predict employee absenteeism or supervisor assessments of their in-role and extra-role performance. Our findings support recent calls for a more nuanced theory and analyses of PSM to help better understand its implications for recruiting, retaining, and motivating the workforce used to provide public goods and services.     

Advancing LGBT Rights in Turkey: Tolerance or Protection?

Tolerance is treated as a virtue and a key principle in liberal theories of the state and human rights. Critics of liberalism have already addressed limitations of tolerance, and the United Nations (UN) introduced broader and more inclusive human rights and non-discrimination norms. Yet, tolerance is still invoked in human rights advocacy, and the UN promotes teaching tolerance as a means to protect human rights. However, there is an asymmetrical relationship between the “tolerant” and the “tolerated,” which must be questioned for its human rights implications. The paper contends that tolerance does not ensure non-discrimination, freedom from persecution, or ending violence. Instead, it can be complicit in violence against lesbian, gay, bisexual, and transgender (LGBT) persons. As an illustrative case, it examines Turkey—a country that has pursued the liberal policy of tolerance by not criminalizing homosexuality—during a reform period that involved further liberalization of law but not the protection of LGBT rights.     

NGOs invite attention: From the United Nations Commission on Human Rights to the Human Rights Council

This article first reviews and compares Human Rights Council and University Period Review (HRC/UPR) research published during and shortly after the institution-building period (2006–2009) to more recent work (2010–2014) to identify patterns of scholarly interest in NGO roles and behavior at the HRC/UPR. It divides research into that which either “ignores” NGOs or offers “indirect” attention, “direct” attention, or “foregrounds” NGO activity, concluding that NGOs are surprisingly underexamined, given remarkable new participatory opportunities in the HRC/UPR and the centrality of NGO information provision to the success of the new body. Empirical analysis of NGO statements from the CHR to the HRC indicates sharply increasing NGO participation, particularly among domestic, regional, and Southern NGOs. The increased volume and changing characteristics of participating NGOs may have important effects on the HRC/UPR and should also encourage further analysis.     

UN Peace Operations and Conflicting Legitimacies

ABSTRACT

Analyses of United Nations (UN) peacekeeping increasingly consider legitimacy a key factor for success, conceiving of it as a resource that operations should seek and use in the pursuit of their goals. However, these analyses rarely break down legitimacy by source. Because the UN is an organization with multiple identities and duties however, different legitimacy sources – in particular output and procedural legitimacy – and the UN’s corresponding legitimation practices come into conflict in the context of peacekeeping. Drawing on a range of examples and the specific case of the United Nations Organization Mission in the Democratic Republic of the Congo (MONUC), this article argues that looking at different legitimacy sources and linking them to the institutional identity of the UN is thus critical, and it shows how the UN’s contradictory legitimation practices can reduce overall legitimacy perceptions.     

Generalized Social Trust and International Dispute Settlement

What determines the success of a peaceful settlement attempt of a border dispute? In order to fully understand why decision makers choose to put an end to an ongoing conflict, it is necessary to consider the social trust levels of the general populations in both states. International conflict settlement requires public support at the domestic level. If a state’s general population perceives the potential dangers of a settlement as too severe, the conclusion of a peace agreement will be difficult. We argue that high levels of social trust allow citizens (1) to favor more conciliatory foreign policies and (2) to be more optimistic about the future behavior of other states. In democratic settings, these public attitudes serve as powerful constraints for decision makers. As a result, high aggregate levels of social trust should be directly related to concession-granting behavior by democracies as well as effective dispute settlement among jointly democratic dyads. We test these expectations with a new aggregate-level measure of social trust and find mixed support for our hypotheses: While trust does not influence the behavior of challenger states, it does have strong effects on democratic target states and jointly democratic dyads.     

Public Perceptions of Income Inequality in Hong Kong: trends,causes and implications

This article examines the patterns and changes in public perceptions of domestic income inequality in Hong Kong in the past two decades and explains individual variations in these perceptions. It found that the perceived seriousness of income disparities had been persistently high, while the perceived unjustness of income disparities showed a fluctuating trend. Our findings lent partial support to the structural position thesis that the privileged groups are less likely than the underprivileged groups to consider existing income disparities to be serious and unjust. Nonetheless, the popular understanding of poverty is still biased towards ‘individual’ explanations, and this perhaps explains why the government is less willing to tackle the economic and political foundations of poverty in Hong Kong.
