A General Robust Approach to the Analysis of Income Distribution, Inequality and Poverty

Income distribution embeds a large field of research subjects in economics. It is important to study how incomes are distributed among the members of a population in order for example to determine tax policies for redistribution to decrease inequality, or to implement social policies to reduce poverty. The available data come mostly from surveys (and not censuses as it is often…

Robust Logistic Regression for Binomial Responses

In this paper robustness properties of the maximum likelihood estimator (MLE) and several robust estimators for the logistic regression model when the responses are binary are analysed analytically by means of the Influence Function (IF) and empirically by means of simulations. It is found that the MLE and the classical Rao's score test can be misleading in the presence of model…

Robust Income Estimation with Missing Data

With income distributions it is common to encounter the problem of missing data. When a parametric model is fitted to the data, the problem can be overcome by specifying the marginal distribution of the observed data. With classical methods of estimation such as the maximum likelihood (ML) an estimator of the parameters can be obtained in a straightforward manner. Unfortunately, it…

Distributional Analysis: a Robust Approach

Distributional dominance criteria are commonly applied to draw welfare inferences about comparisons, but conclusions drawn from empirical implementations of dominance criteria may be influenced by data contamination. We show the conditions under which this may occur and propose empirical methods to work round the proble using both non-parametric and parametric approaches.

Cleavages, opportunities, and citizenship: Political claim-making by the extreme right in France and Switzerland

This very exploratory paper looks at the impact of dominant conceptions of citizenship on the mobilization by the extreme right. Previous work has focused on the role of structural cleavages and institutional opportunities such as party alignments and competition. While we acknowledge the importance of such factors, here we focus on citizenship rights as the relevant political…

Resistance to europeanization: National barriers to supranational changes in migration policy

We argue that the national state remains the main frame of reference in the field of immigration and ethnic relations. The cultural-historical imprint of the pattern of state formation has produced distinct regimes for the incorporation of migrants which largely explain variations in government policies, public debates, and collective mobilizations concerning this policy area. we…

Under The Spotlight: The Impact of Media Attention on Protest Policing

Explanations of protest policing have neglected the "spotlight of the media." Based on data on repression and its media coverage in four Swiss cities from 1965 to 1994, our findings suggest that the mass media do have an impact on levels and forms of repression, along with political opportunity dimensions and levels of disruption. We identify two mechanisms. First, we show…

Statistical Inference for Welfare under Complete and Incomplete Information

We show how a collection of results in the literature on the empirical estimation of welfare indicators from sample data can be unified. We also demonstrate how some of these ideas can be extended to empirically important cases where the data have been trimmed or censored.

Models of citizenship, political opportunities, and the claim-making of immigrants and ethnic minorities: A comparison of France and Switzerland

In this paper we discuss the institutional setting, both cultural and political, for the claim-making of immigrants and ethnic minorities and derive a number of hypotheses regarding variations in the extent, forms, and content of claim-making. The general underlying idea is that the political-institutional setting shapes the modalities of claim-making, while the cultural-…

Corporatism versus social democracy: Divergent fortunes of the Austrian and Swedish labour movements

In Austria, the social democrats suffered major electoral losses in the 1980s and the first half of the 1990s, and these losses translated primarily into gains for right-wing populism. In Sweden, by contrast, the social democrats have pretty much held their own in recent elections (except for 1991) and protest voting has assumed leftist as well as rightist forms. Commonly regarded as…

Was It Worth the Effort? The Outcomes and Consequences of Social Movements

Research on social movements has usually addressed issues of movement emergence and mobilization, yet has paid less attention to their outcomes and consequences. Although there exists a considerable amount of work on this aspect, little systematic research has been done so far. Most existing work focuses on political and policy outcomes of movements, whereas few studies address their…

The Other Side of the Coin: Explaining Crossnational Similarities Between Social Movements

This exploratory essay provides a general framework for the study of crossnational similarities among social movements by looking at three broad social processes: globalization, structural affinity, and diffusion. Each of these concepts is at the core of three apparently rival explanations of movement similarities. The globalization model explains similarities among social movements…

Statistical Inference for Lorenz Curves with Censored Data

Lorenz curves and associated tools for ranking income distributions are commonly estimated on the assumption that full, unbiased samples are available. However it is common to ¯nd income and wealth distributions that are routinely censored or trimmed. We derive the sampling distribution for a key family of statistics in the case where data have been modified in this fashion.
