Identification in a regression discontinuity (RD) design hinges on the discontinuity in the probability of treatment when a covariate (assignment variable) exceeds a known threshold. If the assignment variable is measured with error, however, the discontinuity in the relationship between the probability of treatment and the observed mismeasured assignment variable may disappear. Therefore, the presence of measurement error in the assignment variable poses a challenge to treatment effect identification. This chapter provides sufficient conditions to identify the RD treatment effect using the mismeasured assignment variable, the treatment status and the outcome variable. We prove identification separately for discrete and continuous assignment variables and study the properties of various estimation procedures. We illustrate the proposed methods in an empirical application, where we estimate Medicaid takeup and its crowdout effect on private health insurance coverage.

Highly educated and skilled contract workers come from a range of occupations, have different worker characteristics, and work under organizational practices that are precarious in varied ways. Our current understanding of the experience of contract work does not fully encompass this diversity. This chapter focuses on early-career contract workers who contract across national borders – an increasingly prevalent but little understood phenomenon – to broaden our understanding of contract work. I draw on an analysis of 38 in-depth, semi-structured interviews with 30 international and early-career contract workers in the United Nations (UN) system in Geneva, Switzerland. Eight participants were included in follow-up interviews. I find that my participants demonstrate flexibility to their employer. They accept uncertain and short-term contracts, because they hope to secure longer-term positions within the prestigious UN system. Demonstrating flexibility impacts them, their relationships, and has financial implications as participants center the demands of their contracts. At times, participants place limits on how much uncertainty they will bear. This chapter thus illuminates the experiences of an understudied group of contract workers – early-career workers in transnational settings – who fall within the broad umbrella of contract workers. It highlights how even elite workers experience challenges as they engage in contract work.

Drawing from available literature and several case studies, this research aims to determine the criteria to be considered in shaping a framework regulating Airbnb. This paper will identify the regulatory frameworks of Airbnb from an international perspective and investigate the public perception on the criteria to be considered in shaping the framework regulating Airbnb. The criteria needed to be considered to regulate Airbnb are suggested accordingly.
A quantitative approach based on central tendency statistics was adopted in this research. Questionnaires were administered to the public to investigate the public's opinion on the criteria to be considered to regulate Airbnb. Finally, the criteria to be considered to regulate Airbnb will be determined. By using the mean analysis, this paper will tease out the ranking of the criteria that should be prioritized in shaping the Airbnb regulatory framework.
The results indicated that the criteria of “permits and safety” and “housing rules enforcement” outweigh the other “taxes” and “rule enforcement” criteria and shall be prioritized by the local authorities during the formation of Airbnb regulations in Malaysia.
This paper provides valuable pointers for policymakers before the expansion of Airbnb and before it becomes more difficult to regulate.
The Library Association of Ireland issued last month the first number of An Leabharlann, their new official journal. The title, for those of us who do not speak the language of Erin, means The Library. It is an extremely interesting venture which will be followed by librarians on the mainland with sympathetic curiosity. In particular our readers would be interested in the first of a series of articles by Father Stephen J. Brown, S.J., on Book Selection. The worthy Father lectures on this subject at University College, Dublin, in the Library School. It is mainly concerned with what should not be selected, and deals in vigorous fashion with the menace of much of current published stuff. No doubt Father Brown will follow with something more constructive. Mr. T. E. Gay, Chairman of the Association, discusses the need for a survey of Irish libraries and their resources. We agree that it is necessary. The Net Books Agreement, the Council, Notes from the Provinces, and an article in Erse—which we honestly believe that most of our Irish friends can read—and an excellent broadcast talk on the Library and the Student by Miss Christina Keogh, the accomplished Librarian of the Irish Central Library, make up a quite attractive first number. A list of broadcast talks given by members of the Association is included.

We study research designs where a binary treatment changes discontinuously at the border between administrative units such as states, counties, or municipalities, creating a treated and a control area. This type of geographically discontinuous treatment assignment can be analyzed in a standard regression discontinuity (RD) framework if the exact geographic location of each unit in the dataset is known. Such data, however, is often unavailable due to privacy considerations or measurement limitations. In the absence of geo-referenced individual-level data, two scenarios can arise depending on what kind of geographic information is available. If researchers have information about each observation’s location within aggregate but small geographic units, a modified RD framework can be applied, where the running variable is treated as discrete instead of continuous. If researchers lack this type of information and instead only have access to the location of units within coarse aggregate geographic units that are too large to be considered in an RD framework, the available coarse geographic information can be used to create a band or buffer around the border, only including in the analysis observations that fall within this band. We characterize each scenario, and also discuss several methodological challenges that are common to all research designs based on geographically discontinuous treatment assignments. We illustrate these issues with an original geographic application that studies the effect of introducing copayments for the use of the Children’s Health Insurance Program in the United States, focusing on the border between Illinois and Wisconsin.
