Paper by Nada Hashmi, G. Shankaranarayanan and Thomas W. Malone: “What is the optimal size for online groups that use electronic communication and collaboration tools? Previous research typically suggested optimal group sizes of about 5 to 7 members, but this research predominantly examined in-person groups. Here we investigate online groups whose members communicate with each other using two electronic collaboration tools: text chat and shared editing. Unlike previous research that studied groups performing a single task, here we measure group performance using a test of collective intelligence (CI) that includes a combination of tasks specifically chosen to predict performance on a wide range of other tasks [72]. Our findings suggest that there is a curvilinear relationship between group size and performance and that the optimal group size in online groups is between 25 and 35. This, in turn, suggests that online groups may now allow more people to be productively involved in group decision-making than was possible with in-person groups in the past…(More)”.
All Eyes on Them: A Field Experiment on Citizen Oversight and Electoral Integrity
Paper by Natalia Garbiras-Díaz and Mateo Montenegro: “Can information and communication technologies help citizens monitor their elections? We analyze a large-scale field experiment designed to answer this question in Colombia. We leveraged Facebook advertisements sent to over 4 million potential voters to encourage citizen reporting of electoral irregularities. We also cross-randomized whether candidates were informed about the campaign in a subset of municipalities. Total reports, and evidence-backed ones, experienced a large increase. Across a wide array of measures, electoral irregularities decreased. Finally, the reporting campaign reduced the vote share of candidates dependent on irregularities. This light-touch intervention is more cost-effective than monitoring efforts traditionally used by policymakers…(More)”.
A Landscape of Open Science Policies Research
Paper by Alejandra Manco: “This literature review aims to examine the approach given to open science policy in the different studies. The main findings are that the approach given to open science has different aspects: policy framing and its geopolitical aspects are described as an asymmetries replication and epistemic governance tool. The main geopolitical aspects of open science policies described in the literature are the relations between international, regional, and national policies. There are also different components of open science covered in the literature: open data seems much discussed in the works in the English language, while open access is the main component discussed in the Portuguese and Spanish speaking papers. Finally, the relationship between open science policies and the science policy is framed by highlighting the innovation and transparency that open science can bring into it…(More)”
When do “Nudges” Increase Welfare?
Paper by Hunt Allcott, Daniel Cohen, William Morrison & Dmitry Taubinsky: “Policymakers are increasingly interested in non-standard policy instruments (NPIs), or “nudges,” such as simplified information disclosure and warning labels. We characterize the welfare effects of NPIs using public finance sufficient statistic approaches, allowing for endogenous prices, market power, and optimal or suboptimal taxes. While many empirical evaluations have focused on whether NPIs increase ostensibly beneficial behaviors on average, we show that this can be a poor guide to welfare. Welfare also depends on whether the NPI reduces the variance of distortions from heterogenous biases and externalities, and the average effect becomes irrelevant with zero pass-through or optimal taxes. We apply our framework to randomized experiments evaluating automotive fuel economy labels and sugary drink health labels. In both experiments, the labels increase ostensibly beneficial behaviors but also may decrease welfare in our model, because they increase the variance of distortions…(More)”.
Design-led policy and governance in practice: a global perspective
Paper by Marzia Mortati, Louise Mullagh & Scott Schmidt: “Presently, the relationship between policy and design is very much open for debate as to how these two concepts differ, relate, and interact with one another. There exists very little agreement on their relational trajectory with one course, policy design, originating in the policy studies tradition while the other, design for policy, being founded in design studies. The Special Issue has paid particular attention to the upcoming area of research where design disciplines and policy studies are exploring new ways toward convergence. With a focus on design, the authors herein present an array of design methods and approaches through case studies and conceptual papers, using co-design, participatory design and critical service design to work with policymakers in tackling challenging issues and policies. We see designers and policymakers working with communities to boost engagement around the world, with examples from the UK, Latvia, New Zealand, Denmark, Turkey, the UK, Brazil and South Africa. Finally, we offer a few reflections to build further this research area pointing out topics for further research with the hope that these will be relevant for researchers approaching the field or deepening their investigation and for bridging the academic/practice divide between design studies and policy design…(More)”.
Active Urbanism and choice architecture: Encouraging the use of challenging city routes for health and fitness
Paper by Anna Boldina, Paul H. P. Hanel & Koen Steemers: “Inactivity is one of the major health risks in technologically developed countries. This paper explores the potential of a series of urban landscape interventions to engage people in physical activity. Online surveys were conducted with 595 participants living in the UK by inviting them to choose between conventional pavement or challenging routes (steppingstones, balancing beams, and high steps) using photorealistic images. Across four experiments, we discovered that 80% of walkers claim they would pick a challenging route in at least one of the scenarios, depending on perceived level of difficulty and design characteristics. Where a challenging option was shorter than a conventional route, this increased the likelihood of being chosen by 10%, and the presence of handrails by 12%. This suggests that people can get nudged into physical activities through minor changes to the urban landscape. We discuss implications for policy makers and urban designers…(More)”.
The potential of Facebook advertising data for understanding flows of people from Ukraine to the European Union
Paper by Umberto Minora et al: “This work contributes to the discussion on how innovative data can support a fast crisis response. We use operational data from Facebook to gain useful insights on where people fleeing Ukraine following the Russian invasion are likely to be displaced, focusing on the European Union. In this context, it is extremely important to anticipate where these people are moving so that local and national authorities can better manage challenges related to their reception and integration. By means of the audience estimates provided by Facebook advertising platform, we analyse the flows of people fleeing Ukraine towards the European Union. At the fifth week since the beginning of the war, our results indicate an increase in the number of Ukrainian stocks derived from Ukrainian-speaking Facebook user estimates in all the European Union (EU) countries, with Poland registering the highest percentage share (33%) of the overall increase, followed by Germany (17%), and Czechia (15%). We assess the reliability of prewar Facebook estimates by comparison with official statistics on the Ukrainian diaspora, finding a strong correlation between the two data sources (Pearson’s ?=0.9r=0.9, ?<0.0001p<0.0001). We then compare our results with data on refugees in EU countries bordering Ukraine reported by the UNHCR, and we observe a similarity in their trend. In conclusion, we show how Facebook advertising data could offer timely insights on international mobility during crises, supporting initiatives aimed at providing humanitarian assistance to the displaced people, as well as local and national authorities to better manage their reception and integration…(More)”.
Economic Research on Privacy Regulation: Lessons from the GDPR and Beyond
Paper by Garrett Johnson: “This paper reviews the economic literature on the European Union’s General Data Protection Regulation (GDPR). I highlight key challenges for studying the regulation including the difficulty of finding a suitable control group, variable firm compliance and regulatory enforcement, as well as the regulation’s impact on data observability. The economic literature on the GDPR to date has largely—though not universally—documented harms to firms. These harms include firm performance, innovation, competition, the web, and marketing. On the elusive consumer welfare side, the literature documents some objective privacy improvements as well as helpful survey evidence. The literature also examines the consequences of the GDPR’s design decisions and illuminates how the GDPR works in practice. Finally, I suggest opportunities for future research on the GDPR as well as privacy regulation and privacy-related innovation more broadly…(More)”.
An infrastructure for building policy capability – lessons from practice
Paper by Sally Washington: “The Covid-19 pandemic highlighted the importance of good systems for policy and decision-making. An effective policy system depends on robust policy capability. This article articulates key dimensions of policy capability based on the practical experience of policy practitioners from a range of jurisdictions. It briefly draws on the literature on policy making and organizational capability before situating the key components of policy capability as mutually reinforcing parts of a policy capability infrastructure. These include “supply side” components of leadership, policy quality systems, people capability, and effective internal and external engagement, as well as the “demand side” component of the political administrative interface that shapes and is shaped by policy capability in the public service. This framing of policy capability as an infrastructure broadens the definition of policy capability from a narrow focus on people and skills to a systemic approach that includes the range of systems and processes that enable and support good government decision-making. The article argues that the policy capability infrastructure could serve as a useful and generic analytical framework for describing, assessing, and improving policy capability in teams, organizations, or across an entire public service. Policy leaders are invited to test the framework and share their insights and results, including with colleagues in academia. If it works in practice, it might also work in theory…(More)”.
Varieties of Mobility Measures: Comparing Survey and Mobile Phone Data during the COVID-19 Pandemic
Paper by Fabian Kalleitner, David W Schiestl, Georg Heiler: “Human mobility has become a major variable of interest during the COVID-19 pandemic and central to policy decisions all around the world. To measure individual mobility, research relies on a variety of indicators that commonly stem from two main data sources: survey self-reports and behavioral mobility data from mobile phones. However, little is known about how mobility from survey self-reports relates to popular mobility estimates using data from the Global System for Mobile Communications (GSM) and the Global Positioning System (GPS). Spanning March 2020 until April 2021, this study compares self-reported mobility from a panel survey in Austria to aggregated mobility estimates utilizing (1) GSM data and (2) Google’s GPS-based Community Mobility Reports. Our analyses show that correlations in mobility changes over time are high, both in general and when comparing subgroups by age, gender, and mobility category. However, while these trends are similar, the size of relative mobility changes over time differs substantially between different mobility estimates. Overall, while our findings suggest that these mobility estimates manage to capture similar latent variables, especially when focusing on changes in mobility over time, researchers should be aware of the specific form of mobility different data sources capture….(More)”.
