Most cities in major agglomerations in Europe started to address the rise of short-term accommodation rentals by introducing regulation designed to protect the local housing stock. The momentum behind the widespread introduction of such regulations can be attributed to qualitative and quantitative factors. This article examines selected fields related to short-term rentals in order to uncover the (structural) triggers or conditions that are necessary and sufficient for municipalities to initiate the regulation of their housing market. The study is based on the systematic examination of the effects of those triggers and their combinations using qualitative comparative analysis (QCA). With this method, we explore the implementation or non-implementation of regulation on a sample of major German cities. The results suggest a universal set of conditions covering three central fields: housing market situation, accommodation market conditions and tourism accommodation demand.

Purpose Short-term rentals are mainly of small flats, which are offered to tourists. Currently, the providers of short-term rentals, in particular Airbnb (ABB), are being criticized in several German cities, on the grounds that shares of residential flats are being removed from the housing market, due to illegitimate misuse as tourist accommodation. Thus, the conventional urban housing markets are contending with a decline in housing supply and increasing rents. This paper aims to support these findings empirically. Design/methodology/approach The paper opted first for a spatial analysis with ArcGIS for ABB in Berlin. Second, different online data requests of periods of up to two months were used to analyze the extent of misuse with regard to the Zweckentfremdungsverbot (misuse prohibition law). Third, analysis of variance was used to analyze rental growth on the ABB markets. The data were collected in different approaches from the website of airbnb.com. Findings The paper provides evidence that 5,555 residential flats are presently being misused by ABB (0.30 per cent of the total housing stock in Berlin) and that many providers of entire flats have more than one offer simultaneously. Moreover, the paper provides the first entire-market overview of ABB in Berlin. It is evident that the ABB market is mainly located centrally and that only a few neighborhoods have large ABB markets. Rental growth is higher in the ABB markets which have a significant share of misused flats, than in the ABB markets which have insignificant shares of misused flats. Originality/value To the authors’ best knowledge, the paper provides the first empirical approach regarding misuse through short-term rentals on a housing market with an innovative design and first-hand data.

Abstract Using Qualitative Comparative Analysis, this article presents a systematic comparison of differences in the institutional success of sociology in 25 European countries during the academic expansion from 1945 until the late 1960s. Combining context-sensitive national histories of sociology, concept formation, and formal analyses of necessary and sufficient conditions, the article searches for historical explanations for both successful and inhibited processes of the institutionalization of sociology. Concretely, it assesses the interplay of political regime types, the continuous presence of sociological prewar traditions, political Catholicism, and the effects of sociological communities in neighboring countries and how their various combinations are related to more or less well-established sociologies. The results can help explain adversary effects under democratic conditions as well as supportive factors under nondemocratic conditions.

Causal Complexity

Fuzzy-set qualitative comparative analysis (fsQCA) has become one of the most prominent methods in the social sciences for capturing causal complexity, especially for scholars with small- and medium- N data sets. This research note explores two key assumptions in fsQCA’s methodology for testing for necessary and sufficient conditions—the cumulation assumption and the triangular data assumption—and argues that, in combination, they produce a form of aggregation bias that has not been recognized in the fsQCA literature. It also offers a straightforward test to help researchers answer the question of whether their findings are plausibly the result of aggregation bias.

This chapter examines the book's theory further by using fuzzy-set qualitative comparative analysis methods, which test for necessary and sufficient causal relationships using the logic of set theory. The data confirm the hypothesis that both the petroleum deficit and the threat to imports must be substantial to trigger anticipatory strategies. Thus, the results reinforce the findings from the previous chapters that coercive vulnerability, as determined by the petroleum deficit and import disruption threat, spurs great powers to adopt anticipatory strategies to reduce the danger of oil coercion. Moreover, the severity of the strategy chosen is consistent with the level of coercive vulnerability faced by the state. The more extreme the deficit and import disruption threat, the more extreme the strategy chosen; the less extreme the deficit and threat, the less extreme the strategy chosen.

The Social

A quarter century ago, in 1987, Charles C. Ragin published The Comparative Method, introducing a new method to the social sciences called Qualitative Comparative Analysis (QCA). QCA is a comparative case-oriented research approach and collection of techniques based on set theory and Boolean algebra, which aims to combine some of the strengths of qualitative and quantitative research methods. Since its launch in 1987, QCA has been applied extensively in the social sciences. This review essay first sketches the origins of the ideas behind QCA. Next, the main features of the method, as presented in The Comparative Method, are introduced. A third part focuses on the early applications. A fourth part presents early criticisms and subsequent innovations. A fifth part then focuses on an era of further expansion in political science and presents some of the main applications in the discipline. In doing so, this paper seeks to provide insights and references into the origin and development of QCA, a non-technical introduction to its main features, the path travelled so far, and the diversification of applications.

Empirical Record

Chapter three provides a medium-N, Qualitative Comparative Analysis (QCA) analysis of the empirical record, assessing the outcomes of all 20 militarised interstate disputes that have taken place in the post-Cold War era. QCA is the most proper method given that the focus of this study is on several conditions and their complex relationship. QCA results show that 9 of the 20 cases of asymmetric militarised disputes resulted in war, confirming the importance of this phenomena. Moreover, the analysis reveals that not a single condition is both necessary and sufficient to explain the minor power's choice to go to war. However, the domestic crisis seems to be of particular importance, as it is a necessary condition for the outcome to occur. While this is somewhat expected, more surprising results indicate that domestic crisis is only sufficient when occurring together with a stable regime and either foreign support or window of opportunity. Likewise, regimes with anomalous beliefs tend to ignore the importance of conditions such as foreign support or window of opportunity. Given the limited number of cases, these results can be further strengthened through case studies, that is, process tracing and counterfactual assessment.

Causal Complexity

Research background: Alongside with the development of configurative comparative analysis aiming at identification of necessary and sufficient conditions, various formal methods used for this purpose have been formulated during the last decades. One of them is qualitative comparative analysis (QCA), one of approaches used for causal explanation of phenomena of cases performed in the field of international economics and global affairs. Purpose of the article: The main purpose of the article is to provide a detailed overview of the QCA method in global context, to define its methodologic foundations and consequently introduce the key concepts of the method. The article also provides a comparison of QCA to typical tools of qualitative and quantitative approaches. On the basis of this part, both pros and cons of QCA are derived. Methods: Basically, the methods of analysis, deduction and comparison are used to fulfil the purpose of the article. The existing and available papers and books coping with the topic of QCA and its position among other research methods are reviewed to provide an overview on the selected method. Findings & Value added: The QCA is a method based on analysing stated relations. It bridges the quantitative and qualitative research and reveals certain patterns based on causal complexity principles, however, it is done regarding heterogeneity and diversity of individual researched cases. It is a method applicable to the middle number of cases, it means too few cases for statistical methods on the other hand too many cases for typical qualitative approaches.

Recent Evaluation

The search for necessary and sufficient causes of some outcome of interest, referred to as configurational comparative research, has long been one of the main preoccupations of evaluation scholars and practitioners. However, only the last three decades have witnessed the evolution of a set of formal methods that are sufficiently elaborate for this purpose. In this article, I provide a hands-on tutorial for qualitative comparative analysis (QCA)—currently the most popular configurational comparative method. In drawing on a recent evaluation of patient follow-through effectiveness in Lynch syndrome tumor-screening programs, I explain the search target of QCA, introduce its core concepts, guide readers through the procedural protocol of this method, and alert them to mistakes frequently made in QCA’s use. An annotated replication file for the QCApro extension package for R accompanies this tutorial.
