The chapter considers the ethical problems engendered by random assignment and privacy concerns in randomised controlled experiments and cluster randomised trials. The particular focus is on procedural, legislative and technical approaches to reducing or avoiding the problems. Examples are given from a variety of disciplines including health and education, though the main emphasis is on research in crime and delinquency.

In the past decade, microfinance institutions (MFIs) have experienced a boom in innovations of lending products, partly fueled by donors who see microfinance as the next promise to alleviate poverty. Examples of these new products are the combination of credit with health or life insurance, business and health education, savings products, and the adoption of (or conversion to) individual loan liability. The add-on features generally aim at reducing the vulnerability of clients while contributing to asset creation, hence improving repayment rates and the sustainability of the service. The product innovations typically result from organizations striving to extend outreach, increase impact, and promote sustainability. As in other industries, MFIs typically decide whether to adopt new strategies based on other MFIs’ success with the innovations. Many new microlending products and approaches continue to be developed. However, MFIs must generally rely on qualitative and descriptive case studies and anecdotal evidence on the effectiveness of these innovations to decide whether to implement the new strategies. The usual case study approach does not provide tangible evidence that can enable other organizations to know what changes can be expected if they were to adopt similar product changes.

The use of behavioral insights and experimental methods has recently gained momentum among health policy-makers. There is a tendency, however, to reduce behavioral insights applications in health to “nudges,” and to reduce experiments in health to “randomized controlled trials” (RCTs). We argue that there is much more to behavioral insights and experimental methods in health economics than just nudges and RCTs. First, there is a broad and rich array of complementary experimental methods spanning the lab to the field, and all of them could prove useful in health economics. Second, there are a host of challenges in health economics, policy, and management where the application of behavioral insights and experimental methods is timely and highly promising. We illustrate this point by describing applications of experimental methods and behavioral insights to one specific topic of fundamental relevance for health research and policy: the experimental elicitation and econometric estimation of risk and time preferences. We start by reviewing the main methods of measuring risk and time preferences in health. We then focus on the “behavioral econometrics” approach to jointly elicit and estimate risk and time preferences, and we illustrate its state-of-the-art applications to health.

The main purpose of this study is to increase the understanding of consumer behaviour with respect to (r)e‐tail borrowing, performed under different (more or less generous) delivery and return policies.

The study was designed as a randomised controlled experiment with a random sample strategy. Among the 192,482 Swedish customers who had made an order at nelly.com during the previous 12 months and were to receive the quarterly nelly.com newsletter in November 2010 by e‐mail, 4,000 were randomly selected and randomised into four groups of 1,000 in each group.

The experiment revealed certain purchase and return patterns that support the conclusion that (r)e‐tail borrowing behaviour exists in fashion e‐commerce. Evidence was also found that lenient delivery and returns policies seem to reinforce (r)e‐tail borrowing behaviour, albeit not always in expected ways.

Differences in delivery and return policies seem to impact consumer purchase and return behaviour differently depending on the type of item. Therefore a more differentiated view of how to apply them is suggested. Offering the same delivery and return policies to all types of customers and products is generally not optimal with respect to profitability.

The paper illustrates the need to consider both delivery and returns policies together with customer and product categories simultaneously when applying them in an e‐commerce context.

The purpose of this paper is to argue that the time is ripe to establish a powerful tradition in Experimental International Business (IB). Probably due to what the Arjen van Witteloostuijn refers to as the external validity myth, experimental laboratory designs are underutilized in IB, which implies that the internal validity miracle of randomized experimentation goes largely unnoticed in this domain of the broader management discipline.

In the following pages, the author explains why the author believes this implies a missed opportunity, providing arguments and examples along the way.

Although an Experimental Management tradition has never really gained momentum, to the author, the lab experimental design has a very bright future in IB (and management at large). To facilitate the development of an Experimental IB tradition, initiating web-based tools would be highly instrumental. This will not only boost further progress in IB research, but will also increase the effectiveness and playfulness of IB teaching.

Given the high potential of an Experimental IB, the Cross-Cultural and Strategic Management journal will offer a platform for such exciting and intriguing laboratory work, cumulatively contributing to the establishment of an Experimental IB tradition.

The purpose of this paper is to describe how the Philadelphia Police Department instituted a large‐scale randomized controlled trial of foot patrol as a policing strategy and experienced 23 percent fewer violent crimes during the treatment period. The authors examine whether activities patrol officers were conducting might have produced the crime reduction. The activities of foot and car patrol officers research takes a closer look at what types are examined separately and differences between car patrol activities pre‐intervention and during the intervention are explored. Activities of foot versus car patrol officers during the study period are compared across treatment and control areas.

Official data on police officer activity are used to compare activities conducted by foot patrol officers with those by car patrol officers in 60 treatment (foot beat) and 60 control areas consisting of violent crime hot spots. Activities of car patrol officers are described pre‐intervention and during the intervention. Foot patrol officers’ activities are described within treatment and control areas during the treatment phase of the experiment. Car patrol officers’ activities are reported separately. The statistical significance of changes in car patrol activity pre and during intervention is evaluated using a series of mixed model ANOVAs.

There were noticeable differences in the activities conducted by foot and car patrol. Foot patrol officers spent most of their time initiating pedestrian stops and addressing disorder incidents, while car patrol officers handled the vast majority of reported crime incidents. Car patrol activity declined in both treatment and control areas during the intervention but there was no statistically significant difference between the treatment and the control areas.

The major limitation of this study is the restricted set of data describing officer activity that is captured by official records. Future studies should include a more robust ethnographic component to better understand the broad spectrum of police activity in order to more effectively gauge the ways in which foot patrol and car‐based officers’ activities interact to address community safety. This understanding can help extend the literature on “co‐production” by highlighting the safety partnerships that may develop organically across individual units within a police organization.

The study provides evidence that individual policing strategies undertaken by agencies impact one another. When implementing and evaluating new programs, it would be beneficial for police managers and researchers to consider the impact on activities of the dominant patrol style, as necessary, to understand how a specific intervention might have achieved its goal or why it might have failed to show an effect.

The research contributes to the understanding of the separate and joint effects of foot and car patrol on crime. In addition, it provides police managers with a clearer picture of the ways in which foot patrol police and car‐based officers work to co‐produce community safety in violent inner‐city areas.

Misinterpretation of a negative test results in health screening may initiate less preventive effort and more future lifestyle-related disease. We predict that misinterpretation occurs more frequently among individuals with a low level of education compared with individuals with a high level of education.

The empirical analyses are based on unique data from a randomized controlled screening experiment in Norway, NORCCAP (NORwegian Colorectal Cancer Prevention). The dataset consists of approximately 50,000 individuals, of whom 21,000 were invited to participate in a once only screening with sigmoidoscopy. For all individuals, we also have information on outpatient consultations and inpatient stays and education. The result of health behaviour is mainly measured by lifestyle-related diseases, such as COPD, hypertension and diabetes type 2, identified by ICD-10 codes.

The results according to intention-to-treat indicate that screening does not increase the occurrence of lifestyle related diseases among individuals with a high level of education, while there is an increase for individuals with low levels of education. These results are supported by the further analyses among individuals with a negative screening test.

This paper details an experimental study (n=197) that explores how different types of managerial change justifications affect employees’ reactions. The purpose of this paper is to explore the impact of managerial justification of a controversial decision in referential terms, ideological terms or a combination of the two.

A randomized controlled experiment was used applying case-based video clips to ensure vividness and realism in the experimental manipulation.

The results show that referential justification caused a drop in the perceived trustworthiness of management, such that it reduced employees’ perceptions of the manager’s integrity. The effect was most pronounced in participants having elevated levels of dispositional resistance to change. The drop in perceived integrity was indirectly associated with reduced intention to support the change together with adverse affective and cognitive reactions to change.

A robust test of different change justifications in a randomized, controlled setting, which also highlights the psychological mechanisms through which referential change justifications reduce follower trust. This result should help managers more readily understand the components of successful communication in organizational change.

Body-worn cameras (BWCs) are quickly becoming standardized police equipment. Axon Enterprise, a United States company based in Scottsdale, Arizona, is currently the worldwide purveyor of BWCs having near-complete control over the police body camera market. In 2012, the company launched their Axon Flex body camera alongside claims about the efficacy of these devices. While the research is expanding, scholarship has yet to explore the role that stakeholders like Axon may play in the implementation of body cameras across police services. This empirical chapter examines claims made by Axon in media in relation to the efficacy of their body cameras over a six-year period (2012–2018). Three themes relative to our analysis of Axon claims emerged: officer and community safety; cost and officer efficiency; and accountability and transparency. A basic finding that cut across all three themes is that most of Axon's claims appear to be shaped by beliefs and assumptions. We also found that Axon's claims were mostly predicated on the market (i.e., financial considerations), rather than say scientifically or legally grounded. Some suggestions for future research are noted.
