Price Effects of Horizontal Mergers - A Retrospective on Retrospectives

Abstract The comprehensive review of ex-post merger studies presented assesses the price effects of horizontal transactions to determine whether there are common post-merger price effects, both overall and in specific markets with the aim to derive implications for policy makers and competition authorities in terms of effective merger enforcement and competition policy. The review combines and further analyzes the results of 52 retrospective studies on 82 mergers or horizontal transactions. Overall, it will be shown that the sector in which the respective transaction takes place alone is not a strong indicator of the direction of price-related merger effects. In contrast, the ‘size’ or ‘importance’ of a transaction, as well as market concentration seem to be correlated with post-transaction price increases, especially in already highly concentrated markets. The review and presentation are intended to demonstrate the overall importance of ex post evaluations of antitrust decisions for ex ante competition policy and enforcement.

Bio: After studying media economics, Annika Stöhr completed her PhD on “Economic Evaluation and Reform Implications of German Competition Policy” with a focus on merger control and in particular on non-economic effects and so-called public interests that (should) potentially influence competition regulation. Her research generally operates at the intersection of competition economics, competition law and competition policy, under the premise that innovation and dynamism are both facilitators and goals of functioning competition (regulation). Her current work deals with the regulation of large digital ecosystems, e.g. through Section 19a GWB and the DMA and DSA, as well as with the regulation of algorithmic recommender systems in particular.

Her research benefits from more than two years of professional experience at the German Federal Ministry of Economic Affairs and Climate Action. Since April 2023 she is working as a postdoctoral researcher at the Chair of Economic Theory at Ilmenau University of Technology.

Strategic Behavior and AI Training Data

Abstract: Human-created works represent critical data inputs to artificial intelligence (AI). Strategic behavior can play a major role for AI training datasets, be it in limiting access to existing works or in deciding which types of new works to create or whether to create new works at all. We examine creators’ behavioral change when their works become training data for AI. Specifically, we focus on contributors on Unsplash, a popular stock image platform with about 6 million high-quality photos and illustrations. In the summer of 2020, Unsplash launched an AI research program by releasing a dataset of 25,000 images for commercial use. We study contributors’ reactions, comparing contributors whose works were included in this dataset to contributors whose works were not included. Our results suggest that treated contributors left the platform at a higherthan-usual rate and substantially slowed down the rate of new uploads. Professional and more successful photographers react stronger than amateurs and less successful photographers. We also show that affected users changed the variety and novelty of contributions to the platform, with long-run implications for the stock of works potentially available for AI training. Taken together, our findings highlight the trade-off between interests of rightsholders and promoting innovation at the technological frontier. We discuss implications for copyright and AI policy.

What happens when green technology meets reality: On the environmental impacts of the digital sharing economy

Abstract:  The digital sharing economy is commonly seen as a promising circular consumption model that could potentially deliver environmental benefits through more efficient use of existing product stocks. Yet whether sharing is indeed more environmentally benign than prevalent consumption models remains unclear. First, sharing might not displace the product it is expected to. For example, Uber might displace walking rather than private cars. Second, sharing might necessitate additional products and services to support the sharing operation. Finally, economic incentives to participate in the sharing economy may raise demand for durable products. Our research suggests that the environmental impact of the sharing economy is more nuanced than previously thought.

Tamar Meshulam is a Ph.D. student at Ben-Gurion University, focusing on researching the environmental impacts of technology, particularly within the sharing economy, utilizing data science and industrial economy methodologies. With a background in both Environmental Management (M.Sc.) and Computer Science (B.Sc.) from Tel Aviv University, Tamar brings a multidisciplinary approach to her research. Prior to her academic pursuits, Tamar accumulated over 15 years of experience in the IT industry.

Industrial Data Sharing: The Unintended Consequences of the EU's Data Act

Abstract: The Data Act is a new law forthcoming in the European Union that regulates access to the data produced by IoT devices, especially in an industrial context such as smart manufacturing or smart farming. It aims at facilitating the emergence of new, innovative data-driven services that ultimately yield more efficient market outcomes and higher consumer surplus.
We offer a first analytical study of the economic consequences of the Data Act.  Our analysis suggests that due to the broad application scope of the Data Act, in many situations, the Data Act may likely reduce, and not increase market efficiency. In particular, the Data Act runs potentially contrary to its policy objective when new data-driven services are substitutes to the IoT device manufacturer’s own service, and the IoT manufacturer only has limited market power; or when the new service is a complement to the IoT device manufacturer’s own service, irrespective of market power. Our analysis suggests that the Data Act should adopt a more targeted approach, depending on the type of data-driven service seeking access to data, and the market power of the IoT manufacturer that is required to provide data access.

The paper is a joint work with Jan Krämer.

Tackling Online Misinformation with Generative AI: A comparison of ChatGPT and Microsoft CoPilot

Abstract: The talk will cover a recent study on the ability of two large language model (LLM)-based chatbots, ChatGPT and Bing Chat, rebranded to Microsoft Copilot, to detect veracity of political information. The study uses AI auditing methodology to investigate how chatbots evaluate true, false, and borderline statements on five topics: COVID-19, Russian aggression against Ukraine, the Holocaust, climate change, and LGBTQ+ related debates. It compares how the chatbots perform in high- and low-resource languages by using prompts in English, Russian, and Ukrainian. Furthermore, it explores the ability of chatbots to evaluate statements according to political communication concepts of disinformation, misinformation, and conspiracy theory, using definition-oriented prompts. The discussion will focus on the potential of LLM-based chatbots in tackling different forms of false information in online environments, pointing at the substantial variation in terms of how such potential is realized due to specific factors, such as language of the prompt or the topic. It will also provide an outlook into the future studies using similar methodology on a larger set of misinformation items in more languages.

Position Statement of the Max Planck Institute for Innovation and Competition on the Implementation of the Digital Markets Act

Abstract: The Max Planck Institute for Innovation and Competition published a position statement on the implementation of the Digital Markets Act (DMA), laying down harmonised rules for core platform services provided or offered by gatekeepers. The Institute raises awareness about the possible overly broad blocking effects of the DMA on national rules, which may have the unintended consequences of privileging gatekeepers by jeopardizing future national legislative initiatives. This ultimately obstructs the achievement of contestability and fairness in digital markets. A complementary application of competition rules and effective enforcement of the DMA is, against this backdrop, crucial. Yet there is uncertainty over administrative enforcement mechanisms, and it is unclear what role private enforcement plays in the current legal design of the DMA. The position statement identifies and examines challenges in the implementation of the DMA, along with recommendations for overcoming them.

Data sharing or algorithm sharing?

Abstract: Data combination and analytics can generate valuable insights for firms and society as a whole. Multiple firms can do so by means of new technologies that bring the algorithm to the data (“algorithm sharing”) or, more conventionally, by sharing the data (“data sharing”). Algorithm-sharing technologies are gaining traction because of their advantages in terms of privacy, security, and environmental impact. We present a model that allows us to study the economic incentives generated by these technologies for both firms and a platform facilitating data combination. We find that, first, the platform chooses data sharing unless algorithm sharing’s analytics are sufficiently superior to those associated to data sharing. Second, we identify the properties of the analytics benefit function that ensure that algorithm sharing results in a higher total data contribution. Third, we highlight scenarios in which, in presence of data externalities, there can be a mismatch between the choice of the platform and the preference of a social planner.

Synergy of Minds: Balancing Generative AI, Symbolic AI, and Human Intelligence in the Future of Education

Abstract: While the arrival of Generative AI has certainly changed the world it does not, and will not, provide for all the intelligence needs of the world. This talk will discuss the intrinsic limitations of Generative AI in comparison to Symbolic AI (computation) and human intelligence and how future technologies must leverage all three to be most effective.

The talk will then discuss how our current educational system is teaching the wrong content and skills to prepare students for the AI age. With particular focus on computational thinking, a roadmap for a future curriculum will be introduced.

How can AI and its creators serve democracy?

Abstract: Plurality and homogeneity, being and ought, yesterday’s data and the imagination of the (as yet) non-existent, structural conservatism and the inertia of technology v. the drive of humans for political reform, centralisation of power v. division of powers with checks and balances: These are just a few themes on which the culture of global platform technology and AI on the one hand and and human visions of freedom and a democratic future on the other hand clash. But why are these clashes important ? Is it possible that Tech platforms, AI and the ideology of technological solutions as a collateral damage strengthen populist and authoritarian rule ? And that democracy is in a pincer movement between Tech platforms, AI and authoritarianism ? 

While China is a dictatorship and the US Democracy in a deep crisis, these two powers are held out as models of technological leadership. But do we want to live in a world in which either global corporations or authoritarian political leaders rule, and freedom of individuals as well as democracy have no primacy over technology, business models and absolutist ideologies ?

In his talk, Paul Nemitz discusses how engineers and programmers can re- engage with democracy and stay clear in their work of both the neoliberal wet dream of a world in which technology and technological competition alone determine the rules of how we live, how power, opportunity and wealth is distributed in society and a world view which degrades technology to a tool of totalitarian government’s absolute rule over people. 

What the world needs today are “Engineers for democracy”, thus people who design platforms and AI which strengthen and support Democracy rather than undermining and destroying it. At the beginning of any such project stands an Intention and an Understanding why democracy is worth developing for.

Proposing a Computer Science Approach to Antitrust

Abstract: Computer scientists use the Byzantine Generals Problem as an analogy for the coordination problem among computers in a distributed network by considering that some computers might be unreliable. The Byzantine Generals Problem is a ‘trust’ problem. In my paper “Using Computer Science to Detect Cheat Tolerant Cartels” I use this problem and its algorithmic solutions to analyze how potentially computers can build strong cartels that can tolerate cheating, thus unreliable computers. These solutions work in abstract, thus potentially in both a computer and non-computer situations. Using the case of cheat tolerant cartels, I propose a computer science approach to complement the present law-and-economics antitrust analysis.

Raising Our Sights (A Long Rant From an Accidental Engineer)

Abstract: Engineers typically seek progress through technical innovation. This approach has brought us many wonders, from the transistor to the Internet to virtualization and the cloud. However, some forms of progress are less about technical innovations and more about changing the structure and behavior of the overall technology ecosystem (e.g., the companies involved and how they interact with each other and with customers). This talk will discuss how we can “raise our sights” to address these larger issues — in areas such as the Internet, the cloud, and personal privacy — and what that will require from our own ecosystem of innovation.

Scott Shenker spent his academic youth studying theoretical physics but soon gave up chaos theory for computer science. Continuing to display a remarkably short attention span, his research over the years has wandered from performance modeling and networking to game theory and economics. Unable to focus on any single topic, his current research projects include various topics in networking, system design, and privacy mechanisms. However, despite all these distractions and many decades of therapy, he has never overcome his obsession with Internet architecture. Unable to hold a steady job, he currently splits his time between the International Computer Science Institute (ICSI) and the UC Berkeley Computer Science Division. He is indebted to his many collaborators for inspiring him intellectually while patiently enduring his terrible sense of humor and his tyrannical approach to collaborative writing.

Refractions and Reconfigurations of Pasts, Presents and Futures – Articulating the Relations between Data Integration and Algorithmic Predictions in Data Analysis Platforms

Abstract: This talk offers a conceptualization and analytical framework for the study of data analysis platforms. Starting from a theoretical focus on how data, algorithms and technological systems work as ‘digital prisms’ that refract and reconfigure social phenomena, my work articulates how data integration and data-driven prediction can be seen as forms of knowledge production that allow for new dynamics of seeing, knowing and governing. On this backdrop, the talk highlights five analytical dimensions of data analysis platforms (domains, datasets, models, humans and temporality) and offers a conceptualization of three different types and uses of data analysis platforms (merging, prognosis and projection). Taken together, the components of this analytical framework may guide conceptual and empirical investigations in this area of research. My goal is to contribute to emergent work seeking to articulate the shapes and workings of data analysis platforms as a sub-type of digital platforms. The theorization and empirical study of data analysis platforms is an important endeavor that may help us understand phenomena such as the digitalization and datafication of work and knowledge production, the reliance of the public sector on commercial platforms from the private sector, and broader questions about how data, algorithms and digital systems are used in attempts to grasp and shape futures.

The Bright Side of the GDPR: Welfare-Improving Privacy Management

Abstract: We study the GDPR’s opt-in requirement in a model with a firm that provides a digital service and consumers who are heterogeneous in their valuations of the firm’s service as well as the privacy costs incurred when sharing personal data with the firm. We show that the GDPR boosts demand for the service by allowing consumers with high privacy costs to buy the service without sharing data. The increased demand leads to a higher price but a smaller quantity of shared data. If the firm’s revenue is largely usage-based rather than data-based, then both the firm’s profit and consumer surplus increase after the GDPR, implying that the GDPR can be welfare-improving. But if the firm’s revenue is largely from data monetization, then the GDPR can reduce the firm’s profit and consumer surplus.

Moderating Monopolies

Abstract: Industrial organization predetermines content moderation online. At the core of today’s dysfunctions in the digital public sphere is a market power problem. Meta, Google, Apple, and a few other digital platforms control the infrastructure of the digital public sphere. A tiny group of corporations governs online speech, causing systemic problems to public discourse and individual harm to stakeholders. Current approaches to content moderation build on a deeply flawed market structure, addressing symptoms of systemic failures at best and cementing ailments at worst.

Data Marketplaces and the Data Governance Act: A Business Model Perspective

Abstract: The Data Governance Act sets up a harmonised framework for the development of trustworthy data intermediation services in the EU to enable a neutral and competitive environment for data sharing. These new regulations create some friction with the trends observed in the market, and with the business models data intermediaries are adopting.

This talk maps out some of these technical frictions and regulatory challenges arising in the data economy and marketplaces. First, it sets out the regulatory framework around the EU’s digital strategy, with a particular focus on the Digital Governance Act and the burdens imposed on data intermediaries as set out from their definition in Article 2(11), while also touching upon the Digital Services Act and the Digital Markets Act. Second, it discusses real examples of friction points arising from the legal separation of data intermediaries, from potential limitations to data pricing stemming from the regulation, and from emerging trends such as federated learning or model-based data intermediaries.

13 Propositions on an Internet for a “Burning World”

Abstract: In this paper, we outline thirteen propositions on the state of the Internet and digital infrastructures. The core of our theses is that the centralizing Internet of today will not be sustainable and resilient, neither in terms of its energy needs nor in the face of a “burning world”, i.e., the rapidly changing world, facing an unprecedented human-made climate disaster and countless other shifts we currently find ourselves living in. Furthermore, we highlight that ongoing policy decisions do not necessarily benefit the resilience of the Internet in the future to come. Our propositions are based on our own research contributions published in the past, public discourse, and most certainly rooted in system administration lore and our own experience as system administrators. They are intentionally bold, to form a foundation for discussion, and we make no personal claim to originality and completeness. Finally, we note that, they do not aim at providing simple solutions, but hint at interrelations and challenges we must resolve to survive the future to come.

Tobias works on understanding how we operate networked systems, and how the way we operate them impacts security. For that, he combines classical network measurement with methods from the field of human factors. He got his PhD in 2017, and joined the MPI after being a (permanent position) assistant professor at TU Delft from 2017 to 2022.

Should the control of economic power (still) be the main focus of competition policy?

Abstract: This talk explores the historical and current dimensions of the argument that competition policy should focus on a single (albeit broad) goal; namely the control of (economic) power in the private sphere.

The talk is broadly divided into three chapters:

The historical part considers concentration and the legitimacy of private power as the original predicament of liberalism and one of the great paradoxes of modernity and how these assumptions shaped early antitrust and competition law doctrines.

Moving on to doctrines from the 1970’s, it acknowledges the achievements but also critiques the rise of ‘modern’ antitrust and competition policy and its focus on a narrow set of effects and consumer welfare.

Finally, it considers  the renewed scepticism about economic power and analyses the novel traits, risks and manifestations of power in the digtial world. It asks whether a single and broad policy aim can still serve competition policy better than a multitude or plethora of goals and what the function of competition law ought to be in the context of new regulatory frameworks.

Sharing economy, platforms and cities: empirical studies on Airbnb

Abstract: Airbnb is a prime example of the success and robust growth of peer-to-peer platforms. While Airbnb has been initially described as a sharing economy platform, providing services based on under-utilized assets, over time the role of professional hosts has increased. The impressive growth and rising professionalisation of Airbnb raise crucial questions about its overall impact on local residents in urban environments. In this presentation, I will provide a brief overview of my research on Airbnb in major European cities. I will present results on:

  • To what extent Airbnb is part of the sharing economy
  • The relationship between location variables and price
  • The spatial patterns of Airbnb
  • The spatial differences between listings managed by occasional and professional hosts 
  • The effectiveness of regulations

The presentation will highlight Airbnb in various major cities, including Berlin, Barcelona and London. The studies are based on geographic data science and spatial econometrics methods.

Kristóf is an assistant professor at the Department of Technological Change at the Faculty of Economic Sciences at the University of Warsaw. He is also a researcher at DELab UW (Digital Economy Lab), an interdisciplinary research institute at the University of Warsaw. Kristóf obtained his PhD in Economics in February 2022. In his thesis, he examined the accommodation services provided via Airbnb in the context of their economic impact in major European cities. His research interests include the economics of platforms, urban issues related to digitalization, and the use of data science methods. Kristóf has published as first author in leading high-impact academic journals in the field of management and computational social science, including Journal of Cleaner Production, Tourism Management, and Quality & Quantity. Besides being a PI in his PhD project funded by the National Science Centre in Poland, Kristóf was also a team member in Horizon 2020 projects (part of the European Commission’s Next Generation Internet initiative) focusing on the identification of the social impact of digital technologies.

Competition and value capture in platform markets: Implications for complementor strategy

Abstract: We study how competition between platforms relates to the strategic choices of their complementors. In particular, we are interested in how an increase in competition due to the entry of a new player affects the cooperative value co-creation efforts of complementors on the incumbent platform. Drawing on value capture theory, we argue that this has ambiguous implications for their incentives to continue to cooperate. On the one hand, the entry threatens complementors’ value creation and capture on the incumbent – a demand-side effect that increases cooperation to protect their profitability there. On the other hand, the entrant may constitute an attractive alternative, leading to misaligned value capture expectations on the incumbent – an outside-option effect that decreases their cooperation. We test predictions from a simple theoretical model in the context of the PC video game distribution market: Here, the dominant incumbent “Steam” faced competition with the launch of the “Epic Games Store”. We study two types of (non-)cooperative strategic choices of game developers on Steam: Multihoming by joining the rival, as well as their tendency to participate in Steam sales, which reflects their responsiveness to the incumbent’s most salient orchestration efforts. Our empirical analysis provides broad support for our theoretical predictions: Complementors who are primarily subject to a detrimental demand-side effect increased their cooperation with the incumbent, and those primarily subject to an outside-option effect decreased their cooperation.

Johannes Loh is an Assistant Professor in the Department of Strategy and Entrepreneurship at BI Norwegian Business School. Before, he obtained a PhD from the Institute for Strategy, Technology and Organization at LMU Munich. In his research, he studies questions related to the strategic management and governance of digital multi-sided platforms and online communities, and his work has been published in the Strategic Management Journal. Recent examples include projects on the interplay of platform competition and complementor strategy in the context of the PC video game industry, the role of YouTube’s partnership program in incentivizing content supply, and how online social networks facilitate or stifle the exploration of new products by users of a music platform.

How Polarization Can Help Solve the Misinformation Problem

Abstract: When discussing the ills afflicting social media, there is a great deal of concern about the role played by polarization. While polarization may be part of the misinformation problem, here I present evidence that political motivations are also essential for one of the only possibilities for identifying and combatting misinformation at scale — crowdsourced fact-checking. I will discuss data from survey studies conducted on Lucid and observational analyses of data from Twitter’s crowdsourced fact-checking program. Consistent with theoretical predictions, the results demonstrate that (i) misleading counter-partisan content is flagged more than misleading co-partisan content, (ii) non-misleading content is rarely flagged, and (iii) more politically engaged and extreme users, rather than undermining the system, produce more and better flags. Thus, crowdsourced misinformation identification may succeed because of, rather than in spite of, polarization and political motivations.

Back to What Truly Matters for the Future of Work: Insights from Multistakeholder Dialogue

Abstract: In this PLAMADISO talk, Jovana Karanovic will present findings from the recently released Reshaping Work Report “BACK TO WHAT TRULY MATTERS: Platforms, AI, and Youth in the Workplace.” Key drivers of the future of work include deployment and regulation of digital technologies, such as digital labour platforms and AI, advancing youth employment, and workplace well-being. The EU regulators made significant policy steps throughout 2021 and 2022.

Resonating with the topics at the top of the EU agenda, the Reshaping Work Dialogue facilitated constructive discussions among 32 organisations, representing different viewpoints and expertise to further inspire policy-making, as well as provide concrete solutions to the pressing challenges, specifically regarding: (i) the impact of the platform work directive; (ii) AI in the workplace; (iii) youth employment and workplace well-being.

The report can be downloaded under this link: https://reshapingwork.net/dialogue/2023-report/

Work and Alienation in the Platform Economy – Amazon and the Power of Organization

Abstract: Once hidden behind the veils of entrepreneurship, it is now clear that platforms are reshaping the world of work, and Amazon has been a forerunner in setting the trend.

This book examines two key and contrasting Amazon platforms that differ in how they organize workers: its e-commerce platform and digital labor platform (Mechanical Turk). With access to the people who are working at the heart of these platforms, it explores how different working conditions alienate workers, and how, despite these conditions, workers organize within their political-economic contexts to express their agency in traditional and alternative ways.

Written for social scientists studying and researching the platform economy, this is a timely and important analysis of work and workers on the (digital) shop floor.

Sarrah Kassem is a Lecturer and Research Associate in Political Economy at the Department for Political Science at the University of Tübingen. She completed her PhD in 2020 on the alienation and agency of workers in the Platform Economy, delving more concretely into Amazon’s platforms. Her current teaching and research foci center around workers, working conditions, different forms of labor organization and the intersectional dimensions of the labor movement.

Algorithms in the Wild: Evidence from an Online Marketplace

(joint work with Vito Stefano Bramante, Emilio Calvano, Giacomo Calzolari)

Abstract: Can off-the-shelf repricing algorithms used in online marketplaces learn collusive strategies that harm consumers? To shed light on the sophistication of commercial repricing technology, we deploy our own repricing software on an online platform. We implement a EXP3 repricing algorithm and compare its performance against the artificial intelligence algorithm of a selected commercial repricer. We start by establishing a performance benchmark for myopic pricing strategies when faced with a mechanical repricing rule that undercuts rivals’ prices. When competing against the mechanical rule, our EXP3 algorithm achieves a better performance than the commercial software. Additionally, our EXP3 algorithms out-competes the commercial repricing software in a direct competition. These results cast doubt on the sophistication of the selected commercial repricing software. Designing algorithms that allow for intertemporal trade-offs is a prerequisite for collusion to arise. In simulations, we show that forward-looking strategies can be learned at low costs. This provides the basis for a more in-depth investigation of forward-looking algorithms, and, hence, collusion in future iterations of this work.

Friction-In-Design Regulation as 21st Century Time, Place and Manner Restriction

(joint work with Susan Benesch [Dangerous Speech Project; Harvard University - Berkman Klein Center for Internet & Society])

Abstract: Digital networked society needs friction-in-design regulation that targets the digital architectures, supposedly smart (data-driven, algorithmic) systems, and interfaces that shape human interactions, behavior, and will (beliefs, preferences, values, intentions). The relentless push to eliminate friction for the sake of efficiency has hidden social costs that affect basic human capabilities and society. A general course-correction is needed.

Friction in the digital networked environment can come in many forms. It can be as simple as a time delay prior to publishing a social media post, a notice that provides salient information coupled with a nudge toward actual deliberation, or a query that tests comprehension about important consequences that flow from an action–for example, when clicking a virtual button manifests consent to share information with strangers. We explore many examples using a simple descriptive framework that helps analysts compare and evaluate them.

One major obstacle in the United States to almost any regulation of how private companies design digital networked technologies and govern social interactions online is the First Amendment and its rigorous protections for free speech. The First Amendment has so often been used to strike down government regulation of various forms of speech that it now has a powerful preemptive effect, which some have called First Amendment Lochnerism. We are most concerned with the foreclosure of regulatory imagination and thus consideration and exploration of new regulatory possibilities, such as friction-in-design regulation.

In this article, we clear the First Amendment brush and reveal an open and mostly underappreciated regulatory territory to explore. We argue that friction-in-design regulation should be understood as Twenty-First century time, place and manner restrictions, akin to laws that prohibit using megaphones in the middle of the night, require permits before marches, and prohibit adult theaters in residential neighborhoods. This does not mean that friction-in-design regulation would escape First Amendment scrutiny altogether, of course. But it would trigger intermediate rather than strict scrutiny, so long as the friction-in-design regulation remained content neutral. In other words, not all friction-in-design regulations would qualify as content neutral time, place, and manner restrictions. We discuss various examples.

At the same time, we advance a novel governance theory that casts time, place and manner restrictions as a useful regulatory model to bring online from the offline context and conventional First Amendment jurisprudence. Properly understood, designed and applied, time, place and manner restrictions constitute a system for balancing individual freedom to communicate with the collective (state) interest in maintaining social order and peace, both offline and online.
