Ordered response models

Summary We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models. They are based on an underlying latent model with single index function and constant thresholds. We argue that these approaches are overly restrictive and preclude a flexible estimation of the effect of regressors on the discrete outcome probabilities. For example, the signs of the marginal probability effects can only change once when moving from the smallest category to the largest one. We then discuss several alternative models that overcome these limitations. An application illustrates the benefit of these alternatives. We are grateful to an anonymous referee for valuable comments.     

The Labor Market Consequences of Gender Differences in Job Search

This paper uses data from an Internet-based CV database to investigate if women are more restrictive than men in their choice of search area, and if this is of importance in the early stages of the hiring process. We show that women are less likely to search in the metropolitan areas or far away from where they currently live. Moreover, our results indicate that these differences are important: Female searchers get fewer firm contacts, and we show that this is to a large extent explained by their more restrictive search area. When we include controls for the searchers?? search area, the negative gender effect disappears. However, the results differ somewhat across subgroups: For highly skilled women the search area is important, but there remains an unexplained negative gender effect. Our results suggest that gender differences in job search may be important to consider in studies of gender differences in labor market outcomes.     

Pathways to Collective Protest: Calculation, Identification, or Emotion? A Critical Analysis of the Role of Group-Based Anger in Social Movement Participation

The dual-pathway model of collective action proposes two motivational pathways to collective protest, one is based on cost–benefit calculations and another is based on collective identification . The present research examined the role of feelings of group-based anger as an additional path. Study 1, a field study in the context of students' protest in Germany ( N = 201), provided evidence for a unique effect of anger. Study 2, a laboratory experiment ( N = 182), examined the desire to release aggressive tension as a psychological process underlying this effect. As hypothesized, analyses confirmed that anger affected participants' willingness to protest only to the extent that this behavior provided the opportunity of cathartic reduction in aggressive tensions. Moreover, an experimental manipulation providing an alternative means to release tension reduced the relationship between anger and willingness to protest to nonsignificance. The implications of these findings for reconceptualizing the role of anger in collective protest are discussed.     

SOCIAL DEATH AS SELF-FULFILLING PROPHECY:

In his classic Passing On , David Sudnow described how the presumed social value of patients affects whether the staff will attempt to revive them. Since this study was published, the health care field has undergone dramatic changes and commentators have questioned whether the social rationing described by Sudnow is still relevant. Specifically, critics point to the increased rationalization of medical practice via protocols, a widely accepted resuscitation theory, and legal initiatives to promote resuscitative efforts and protect patient autonomy. Based on observations of 112 resuscitative efforts and interviews with forty-two health care workers, I demonstrate that the recent changes in the health care system did not weaken but instead fostered social inequality in death and dying.     

Hearts Too Good to Die: Claude S. Beck's Contributions to Life-Saving

This paper explores the role of Western Reserve University cardiac surgeon Claude S. Beck in convincing the world of the merits of electric defibrillation to treat the life-threatening heart arrhythmia ventricular fibrillation. Before Beck, the method of electric defibrillation had been experimentally explored at least four times but it never caught on as a medical or first-aid life-saving technique. Beck succeeded because he synchronized three activities: he refined the technique and provided clinical applications, he built a communication infrastructure, and he formulated a vision of who should use the technique under what kind of circumstances.     

Panel data unit roots tests: The role of serial correlation and the time dimension

We investigate the influence of residual serial correlation and of the time dimension on statistical inference for a unit root in dynamic longitudinal data, known as panel data in econometrics. To this end, we introduce two test statistics based on method of moments estimators. The first is based on the generalized method of moments estimators, while the second is based on the instrumental variables estimator. Analytical results for the Instrumental Variables (IV) based test in a simplified setting show that (i) large time dimension panel unit root tests will suffer from serious size distortions in finite samples, even for samples that would normally be considered large in practice, and (ii) negative serial correlation in the error terms of the panel reduces the power of the unit root tests, possibly up to a point where the test becomes biased. However, near the unit root the test is shown to have power against a wide range of alternatives. These findings are confirmed in a more general set-up through a series of Monte Carlo experiments.     

Partisan ideology,veto players and their combined effect on productive and protective welfare policy: how the left still matters after all?

Quantitative analysis of the question whether ‘parties still matter’ has largely focused on the dynamics of aggregated expenditure-based dependent variables or protective welfare policies such as unemployment, sickness and family benefits. This article develops a series of pooled time-series cross-section regression specifications predicting changes in disaggregated protective welfare policies alongside productive welfare policies, namely family services, active labour market programmes and public education, across 17 Western democracies (1971–2010). In so doing, it employs the latest Comparative Manifesto Project [Volkens, A., P. Lehmann, N. Merz, S. Regel, and A. Werner. 2014. The Manifesto Data Collection. Manifesto Project (MRG/CMP/MARPOR). Version 2014b. Berlin: Wissenschaftszentrum Berlin für Sozialforschung (WZB). Accessed January 2015. https://manifestoproject.wzb.eu/information/information] and Veto Player [Jahn, D., T. Behm, N. Düpont, and C. Oberst. 2012. Parties, Institutions & Preferences: Veto Player (Annual), Version 2012–02. Accessed January 2015. http://comparativepolitics.uni-greifswald.de/data.html] data to explore the effect of the ideological position of prime ministers’ parties, veto players and their combined effect on these welfare policy areas. The article confirms that Left and Right governments ceased to make any substantive difference for protective welfare policies from the early 1980s onwards. Yet, it also finds that positive Left partisan effects have largely persisted for productive welfare policies. In the era of global competition, Left party ideology has continued to be an important factor in realising a social investment perspective in practice; in terms of the expansion of family services, its effects have been contingent on the veto power Left prime ministers faced.     

An Experimental Investigation of the Disparity Between WTA and WTP for Lotteries

In this paper we experimentally investigate the disparity between willingness-to-accept (WTA) and willingness-to-pay (WTP) for risky lotteries. The direction of the income effect is reversed by endowing subjects with the highest price of a lottery when asking the WTP question. Our results show that the income effect is too small to be the only source of the disparity. Since the disparity concentrates on a subsample of subjects, parametric and nonparametric tests of the WTA-WTP ratio may lead to contradictory results. The disparity is significantly reduced when background risk is introduced. That is, putting subjects always into a risky position could improve the contingent valuation method, which is often concerned with the assessment of risky situations such as health risks, automobile safety, etc.      

Phases of Earthquake Experience: A Case Study of the June 2000 South Iceland Earthquakes

A case study of the impact factors of stress and relief in the wake of the south Iceland earthquakes in 2000 is presented. By applying axial coding analysis, the isolated concurrent and interplaying sociostructural impact factors were added sequentially to a time axis based on interviews with sufferers, as well as observations and a survey analysis. The data were obtained through a field survey using standardized questionnaires as well as numerous personal in-depth interviews, photographs, and field notes. An exposition of the different phases of the earthquake experience is presented, reflecting the victims' conscious and/or unconscious efforts to bring life back to "normal," though constantly burdened by a perceived lack of understanding of their experiences by "outsiders." The process was characterized by six main stress factors and three noteworthy mitigating factors. The findings are important for vulnerability and risk assessment as well as for planning pre-, pro-, and postearthquake reactions in the affected areas.
