Three years after launching his brick-and-mortar store, X Fire Paintball and Airsoft, Steve Herbert Sr. and his sons began selling products on Amazon.com's third-party Marketplace and online sales expanded rapidly. Over time, X Fire noticed that products of which it had once been the only seller were now being sold by Amazon straight from X Fire's suppliers, effectively cutting X Fire out. Amazon was also ignoring the minimum advertised price (MAP) set by manufacturers. How should X Fire defend itself? Now Amazon representatives were approaching X Fire to encourage them to sell on Amazon's smaller but growing Canadian Marketplace. How should X Fire respond to this opportunity?

In late 2016, the founders of Flatiron School, a startup offering 12-week coding bootcamps, are formulating their growth strategy. Their new online-only program has matched the excellent job placement results for their in-person bootcamps. Should Flatiron shift investment to aggressively expand online, or grow online and in-person bootcamps in tandem? Should they pursue opportunities to sell online programs to universities and corporations, in addition to their direct-to-consumer offer?

The Nanyang Technological University's Energy Research Institute (ERI@N), which focuses on the applied research, development and commercialization of innovative energy solutions, has developed an energy controller that would act as the heart of a microgrid. A microgrid is a local source of electrical power that feeds a relatively small network of electricity users, and even when attached to a centralized regional or national grid, is able to function independently. The ERI@N team in Singapore deploys 210 research staff and 150 PhD students from 26 countries to tackle emerging challenges in the energy industry. Two ERI@N flagship programmes - EcoCampus and the Renewable Energy Integration Demonstrator Singapore (REIDS) - develop and implement working solutions for energy efficiency and renewable energy integration. By 2017, ERI@N had amassed great depth of knowledge on the delivery of distributed energy resources (DER). The immediate challenges for ERI@N are: What is the best path to introduce its microgrid controller to a rapidly evolving market for distributed energy solutions, and how would it sustain its early lead in affordable DER technology?

This article introduces the special issue on the increasing role of cities as a driver for (open) innovation and entrepreneurship. It frames the innovation space being cultivated by proactive cities. Drawing on the diverse papers selected in this special issue, this introduction explores a series of tensions that are emerging as innovators and entrepreneurs seek to engage with local governments and citizens in an effort to improve the quality of life and promote local economic growth.

The prevailing geographic model for high-technology industrial organization has been the "nerdistan," a sprawling, car-oriented suburb organized around office parks. This seems to contradict a basic insight of urban theory, which associates dense urban centers with higher levels of innovation, entrepreneurship, and creativity. This article examines the geography of recent venture capital finance startups across U.S. metros and within a subset of them by neighborhood. It concludes that the model is changing. The suburban model might have been an historical aberration, and innovation, creativity, and entrepreneurship are realigning in the same urban centers that traditionally fostered them.

The article presents a framework for exploring the drivers, structure, and dynamics of open data initiatives in the city context. Drawing on a case study of the city of Barcelona complemented with other cases, it develops a stepwise framework that can serve as a practical guide for both urban and private leaders to implement open data strategies. Following this model can enable managers to minimize risk and effectively harness the power of open data.

Pressures on infrastructure-due to growing urban populations, the ubiquity of new technologies, and collaborative business models-are fostering a new form of entrepreneurship focused on addressing quality of life in cities. Urban entrepreneurs are challenging the logic of formal market structures, forcing us to reframe our thinking around the interactions between place, individuals, institutions, and the resulting innovative outcomes. Urban entrepreneurs-operating at the neighborhood, city, and global levels-are developing alternative forms of private-public-people partnerships and unique business strategies.

Initiatives to redesign cities so that they are smarter and more sustainable are increasing worldwide. A smart city can be understood as a community in which citizens, business firms, knowledge institutions, and municipal agencies collaborate with one another to achieve systems integration and efficiency, citizen engagement, and a continually improving quality of life. This article presents an organizational framework for such collaboration and employs it to analyze Smart Aarhus, the smart-city initiative of Aarhus, Denmark. Based on the experiences of Smart Aarhus to date, it offers a set of lessons that can benefit the designers, leaders, and policymakers of other smart-city initiatives.

Governing a city is arguably one of the most complex management tasks facing organizational leaders. Based on an analysis of Vienna, London, and Chicago, this article demonstrates that city leaders treat cities as ecosystems, structured and governed either as "extended enterprises" where inputs from specialized organizations are coordinated and integrated into the final service or as "platform markets" where direct interactions between third-party service providers and citizens are facilitated by the city leaders. If cities are viewed as the "ecosystem of ecosystems," then successful city governance requires an orchestration approach where leaders choose the appropriate structure and manage the ecosystem dynamically in a constantly changing environment.

The Smart Cities movement has produced a large number of projects and experiments around the world. To understand the primary ones, as well as their underlying tensions and the insights emerging from them, the editors of this special issue of the California Management Review enlisted a panel of experts, academics and practitioners from different nationalities, backgrounds, experiences, and perspectives. The panel focused its discussion on three main areas: new governance models for Smart Cities, how to spur growth and renewal, and the sharing economy both commons and market based.

In 2006, the regional director for Texas' Environmental Defense Fund (EDF) was on his way to a hearing about permits for new coal plants proposed by Texas electricity provider TXU when he received a call from private equity firm Texas Pacific Group, concerning TXU's plans to build 11 new coal-fired power plants. How could he negotiate with the private equity firm as it pursued the largest recorded leveraged buyout deal? The private equity firm was opposed to acquiring a firm embroiled in a pitched battle with environmentalists, and claimed to be willing to make substantial concessions. However, as an environmental non-government organization, EDF would face significant risks if it elected to work with TXU and private equity firms to facilitate this deal. Should EDF support the buyout, and what concessions should it ask for in return?

CompuSoluciones was a value-added distributor of information technology hardware, software, and services based in Guadalajara, Mexico. In 2016, the firm's chief executive officer was aware that the company faced the threat of disintermediation as some of its vendors looked to sell directly to end-users. The industry in which CompuSoluciones competed was known for its rapid technological changes, which affected the design, supply, and price of products, and even the structure of the industry. As an intermediary in the business, CompuSoluciones was threatened by disintermediation, which was enabled by two new technologies: cloud computing and software as a service. If software vendors could interact directly with end-users, they would not need to pay intermediaries (resellers or wholesalers such as CompuSoluciones) to distribute their products. CompuSoluciones's chief executive officer needed to consider what the company could do in the next few months to prevent or slow the process of disintermediation or to participate in the industry in a different way. The decision would have significant implications for the firm's business model.

Twitter Inc. (Twitter), based in California, was a social media platform whose growth had stalled over the past few years. Once a promising tool for individuals looking to broadcast short messages to a network, Twitter had been eclipsed by other platforms such as Facebook, Snapchat, and LinkedIn. Unlike other social media platforms, Twitter limited its users' messages to 140 characters. This format served Twitter well in its early days, but users had turned to other more flexible platforms. In October 2016, Twitter's chief marketing officer faced two main challenges: how to advertise an already popular social media platform to non-users and how to encourage current users to stay with the platform.

Linear regression is a common tool used in statistics and is considered the foundation for most predictive analytics. It creates a line of best fit in a data set and uses that line to explain the relationship between two quantities, which helps forecast future values. This note provides a high-level, non-technical overview of linear regression.
