No claim, no pain. Measuring the non-take-up of social assistance using register data

The main objectives of social assistance benefits, including poverty alleviation and labor-market or social reintegration, can be seriously compromised if support is difficult to access. While recent studies point to high non-take-up rates, existing evidence does not make full use of the information recorded by benefit agencies. Most studies have to rely on interview-based data, with misreporting and measurement errors affecting the variables needed to establish both benefit receipt and benefit entitlement. In this paper, we exploit a unique combination of Finnish administrative data and eligibility simulations based on the tax-benefit calculator of the Finnish authorities, carefully investigating the measurement issues that remain. We find rates of non-take-up that are both substantial and robust: 40 to 50% of those eligible do not claim. Using repeated cross-section estimations for years 1996?C2003, we identify a set of stable determinants of claiming behavior and suggest that changes in behavior could drive the observed downward trend in take-up rates during the post-recession period. We discuss the poverty implications of our results.     

TAX POLICY AND INCOME INEQUALITY IN THE UNITED STATES, 1979–2007

This paper assesses the effects of U.S. tax policy reforms on inequality over around three decades, from 1979 to 2007. It applies a new method for decomposing changes in government redistribution into (1) a direct policy effect resulting from policy changes and (2) the effects of changing market incomes. Over the period as a whole, the tax policy changes increased income inequality by pushing up the income share of high‐income earners (the top 20%). (JEL H23, H31, H53, P16)     

Interface management research in supplier–customer relationships: findings from a citation analysis of international literature

Currently, the terms interface and interface management in the context of interorganisational relationships between suppliers and customers are under intensive discussion. Central issues are the emphasis placed upon the coordination of activities at business interfaces, and the conviction that the concept can make business operations more efficient and thus more effective. That interface management in supplier–customer relationships is discussed in various academic disciplines and characterized by various thematic approaches makes this field complex. Thus the first goal of this article is to investigate the state of interface research, identifying select topics that promise further significant research in the field of interface management in supplier–customer relationships. In addition, based upon a comprehensive citation analysis of 176 journal articles or 4,654 references, the publication development, the important players and the most important academic journals in interface management research in supplier–customer relationships will be briefly presented. Finally, five clusters in interface management research that provide a framework for additional research activities are, based on a co-citation analysis, defined and briefly analysed.     

Mechanics of replacing benefit systems with a basic income: comparative results from a microsimulation approach

Recent debates of basic income (BI) proposals shine a useful spotlight on the challenges that traditional forms of income support are increasingly facing, and highlight gaps in social provisions that largely depend on income or employment status. A universal “no questions asked” public transfer would be simple and have the advantage that no-one would be left without support. But an unconditional payment to everyone at meaningful but fiscally realistic levels would likely require tax rises as well as reductions in existing benefits. We develop a comprehensive BI scenario that facilitates an assessment of the resulting fiscal and distributional effects in a comparative context, undertake a microsimulation study to quantify them, and propose a simple decomposition to identify the mechanisms that drive effects in different country contexts. Results illustrate the challenges, but also the strengths, of existing social protection systems. A BI would fix benefit coverage gaps that exist in many countries, but would require very substantial tax rises if it were to be set at a meaningful level. As support would not be targeted on those most in need, it would not be a cost-effective way of directly reducing income poverty.     

Estimating general variable acceptance sampling plans by bootstrap methods

We consider variable acceptance sampling plans that control the lot or process fraction defective, where a specification limit defines acceptable quality. The problem is to find a sampling plan that fulfils some conditions, usually on the operation characteristic. Its calculation heavily depends on distributional properties that, in practice, might be doubtful. If prior data are already available, we propose to estimate the sampling plan by means of bootstrap methods. The bias and standard error of the estimated plan can be assessed easily by Monte Carlo approximation to the respective bootstrap moments. This resampling approach does not require strong assumptions and, furthermore, is a flexible method that can be extended to any statistic that might be informative for the fraction defective in a lot.
