A Framework for Assessing Democratic Qualities in Collaborative Economy Platforms: Analysis of 10 Cases in Barcelona

The term “collaborative economy” or “collaborative economy platforms” refers to exchange, sharing, and collaboration in the consumption and production of capital and labor among distributed groups, supported by a digital platform. Collaborative economies’ use is growing rapidly and exponentially, creating high expectations of sustainability and their potential to contribute to the democratization of the economy. However, collaborative economy platforms lack a holistic framework to assess their sustainability and pro-democratization qualities. In addition, there is confusion about platforms which present themselves as collaborative when they actually are not, and similar uncertainties and ambiguities are associated with diverse models. To address this confusion, this article provides a framework for assessing the pro-democratic qualities of collaborative economy initiatives. It was applied to 10 cases in the context of the city of Barcelona. The methods used in this study include mapping and typifying 10 collaborative economy cases in the city, structured and in-depth interviews, and a co-creation session. The results indicate the presence of several modalities for favoring democratic values in a collaborative economy.


Introduction
The term "collaborative economy" or "collaborative economy platforms" refers to exchange, sharing, and collaboration in the consumption and production of capital and labor among distributed groups, supported by a digital platform. The use of collaborative economies is growing rapidly and exponentially, bringing high expectations of sustainability for its potential to contribute to the democratization of the economy. However, collaborative economy platforms lack a holistic framework for assessing these sustainability and pro-democratization qualities. In addition, there is confusion about platforms that present themselves as collaborative when they actually are not, and similar uncertainties and ambiguities are associated with diverse models [1].
The disruptive impact of the best-known economy platform model, that of extractionist "unicorn" corporation (a privately held startup company valued at over $1 billion) platforms such as Uber and Airbnb, has provoked huge controversy [2]. Successful "alternative" and truly collaborative models exist, such as open commons, platform cooperativism, and decentralized organizations based on social economy and open knowledge, but these have received limited research attention.
First, this article reviews collaborative economy conceptualization and previous attempts to classify collaborative economies to provide a framework of pro-democratic qualities. Then, we apply the resulting methodology in 10 relevant cases located in the city of Barcelona. At that time, we show the results and, finally, present the conclusions and discussion.

Collaborative Economy
The term collaborative economy or collaborative platforms economy (which can only be considered collaborative and commons-oriented under a particular set of conditions) refers to the exchange (matching supply and demand), sharing and collaborating in the consumption, and production of capital and labor among distributed groups supported by a digital platform [3]. It is growing rapidly and exponentially, and has become a top priority for governments around the globe (i.e., European Commission, 2016 [4]). However, the collaborative economy suffers from important challenges. We would like to highlight and address two of them: (1) The platform collaborative economy is creating high sustainability expectations for its potential to contribute to a sustainable development of society [5][6][7][8][9], and for its potential to contribute to the democratization of economy [10]. However, the platform collaborative economy lacks a holistic framework to assess these sustainability and pro-democratization qualities. Furthermore, the sustainable design of platform has considered questions of technological and economic aspects, but has not integrated other sustainability relevant questions, such as the environmental impact, gender and inclusion, or its policy implications, lacking a proper multidisciplinary perspective of the platform economy; (2) There is a confusion about the platforms which present themselves as collaborative while actually they are not, and similar uncertainties and ambiguities are associated with diverse models. The disruptive impact of the best known platform economy model, that of Unicorn extractionist corporation platforms such as Uber and Airbnb, is provoking huge controversy [2]. Successful "alternative" and truly collaborative models exist, such as open commons, platform cooperativism and decentralized organizations based on a social economy and open knowledge, with examples such as Fairmondo. Nonetheless, these have received neither policy nor research attention. Additionally, there is a lack of a classification system that helps to establish the difference.

Previous Attempts to Classify Models of Collaborative Economy
There have been previous attempts to classify collaborative economies. The Spanish Association of the Digital Economy (Adigital) carried out a study, "Collaborative models are on demand in digital platforms" [11], to distinguish among the activities of: (1) Collaborative Economy: a digital platform serving as an intermediary between equals, either between organizations or individuals, with or without economic consideration; (2) Economy on Demand: a digital platform serving as an intermediary between a professional and a user; and (3) Service Economy: a digital platform that, without disintermediation, connects users with goods for their temporary use, adapting to the effective use time required by users and making the spatial location more flexible.
If we focus on the first group, we see that it includes projects with such highly disparate approaches as AirBnB (a vacation rental platform owned by a multinational) and Goteo (a crowdfunding platform based on commons principles owned by a foundation). In fact, the interface or platform design both conditions and predefines the social relations-related, for example, to interaction mechanisms, regulation, profile information, or promotion-among users [12,13].
Netnographic investigation of 55 collaborative consumption platforms in The Triple Impact Assessment of P2P Collaborative Consumption in Europe project [14] defined three types of collaborative consumption platforms: (1) Network Oriented Platforms (e.g., Airbnb, Blablacar, TimeRepublick, or Eatwith), where users have many forms of communication in order to get digital reputation and show confidence to engage other users; (2) Transaction Oriented Platforms (Vibbo or Nolotiro), with fewer communication and interaction tools, focused on convenience and more connected to the traditional consumer and provider roles; and (3) Community Oriented Platforms (WWOPP voluntaries network, La Colmena que dice sí or CiroSel), linked to a social or environmental mission and to a strong code of conduct. These platforms develop some collective rules beyond self-management regulation based on the capacity of the individuals to manage their confidence networks. Gordo et al. [15] determined the relevance of the transformation of the consumer into an entrepreneur or the new role of prosumer. In the end, in some platforms, users provide knowledge, properties, or services while intermediaries are those Urban Sci. 2018, 2, 61 3 of 13 who really earn money [8]. At the same time, netnographic research highlights the necessity to precisely review how each platform initiative works and the platform's social, economic, and environmental impacts [15,16].
In this context, where a critical and holistic review of digital platforms that promote the collaborative economy is required, a new key concept emerges: "platform cooperativism". According to Scholz [17], a digital platform must be based on collective ownership, decent payment and security of income for its workers, the transparency and portability of the data created, appreciation and recognition of the value generated by the platform's activity, collective decision-making, a protective legal framework, transferable protection of workers and the coverage of social benefits, protection against arbitrary conduct in the rating system, rejection of excessive supervision in the workplace, and, finally, the right of the workers to disconnect. As stated by Scholz, on the one hand, the platforms must be shaped around the values of cooperativism. On the other hand, digital tools must amplify the scalability and the social and economic impact of cooperative organizations. At the same time, Fuster Morell [10] indicated that the very construction of technology platforms is not a minor issue, and that cooperative platforms should adopt open software and licenses. In short, creating a self-managed governance that allows the articulation of community development around the digital commons [18] has to be approached as "open cooperativism" [19], an antithesis of the unicorn and corporate platforms.
There have been previous attempts to establish delimitations in collaborative production or commons-based peer production (CBPP) [20]. This is the case of the four freedoms of free software. The four freedoms are used in relation to whether a particular software program qualifies as "free" software. A program is free software if it adequately gives users all four freedoms. Although the four freedoms for software might resemble what we are trying to do here, CB relates to a collective process and delimitation criteria for the features of that process. By contrast, the definition of free software is individualistically driven and built based on individual freedoms, not the features of the process as a whole.
From our point of view, it is necessary to consider the complexity of the classification of collaborative economy platforms, and specific analyses are required to distinguish models. For example, during the last three years, a new type of agrofood consumer platform was spreading its activity in Barcelona: La Colmena que dice sí. Despite using an approach similar to that of cooperatives to engage potential members (disintermediation between local producers and consumers), the organization's values were far from the values of social and economic solidarity [21]. Departing from this reflection, in this paper, we provide a framework to characterize models of collaborative economy and visualize their qualities.
In this article, we propose a framework for the democratic qualities of collaborative economy platforms. The framework considers the dimensions of governance design, economical strategy, technological base, knowledge policies, and social responsibility regarding externalization impact of the platforms. The democratic balance is an analytical tool that helps to visualize the democratic qualities of collaborative economy initiatives, differentiate models, provide insight into the sustainability of their design, and inform technological development (see Figure 1). Urban Sci. 2018, 2, 61 4 of 13 example, during the last three years, a new type of agrofood consumer platform was spreading its activity in Barcelona: La Colmena que dice sí. Despite using an approach similar to that of cooperatives to engage potential members (disintermediation between local producers and consumers), the organization's values were far from the values of social and economic solidarity [21].

A Framework of Democratic Qualities of Collaborative Economy Platforms
The democratic qualities of the collaborative economy are articulated around three main dimensions, with in six subdivisions: 1. Governance and Economic: We believe that these two sub-dimensions are interconnected. Thus, the way that the project or platform is governed is connected to the underlying economic model.
1.a. Governance: This aspect regards democratic enterprises and involving the community generated value in the platform governance. This aspect also regards the decision-making model of the organization, and mechanisms and political rules of participation in the digital platform.
1.b. Economic model: This aspect regards whether the project's financing model is based on private capital, ethical finance, or a distributed fund (crowdfunding or match-funding), the business models, mechanisms of economic transparency, how far profitability is driven in the whole plan, distribution of value generated, and equity payment and labor rights. This aspect regards ensuring equitable and timely remuneration, and access to benefits and rights for workers (maximization of income, salary predictability, safe income, protection against arbitrary actions, rejection of excessive vigilance at the workplace, and the right to disconnect).
2. Knowledge and Technological policies: In the same sense, knowledge and technological policies are interconnected. Thus, the adoption of certain technological tools or licenses is going to impact the way the platform promotes knowledge.
2.a. Knowledge policy: Regards the property type, as established by the license used (free licenses or proprietary licenses) for the content and knowledge generated, type of data (open or not), the ability to download data (and in which formats), and the promotion of the transparency of algorithms, programs, and data. This aspect regards privacy awareness, the protection of property including personal data, and preventing abuse and the collection or sharing of data without consent. This aspect also regards guaranteeing the portability of data and reputation.
2.b. Technological policy: This aspect regards the mode of property and freedom associated with type of software used and its license (free or proprietary) and the model of technology architecture: distributed (using blockchain, for example) or centralized (software as a service).
3. Social responsibility and impact. These dimensions relate to any source of awareness and responsibility regarding the externalities and negative impacts, such as social exclusion and social inequalities, the inclusion of gender, regarding the equal access to the platform of people with all kinds of income and circumstances in an equitable and impartial way (without discrimination). This aspect regards compliance with health and safety standards that protect the public, and the environmental impact (promoting sustainable practices that reduce emissions and waste, taking into account the rebound effect they can generate and the most efficient use of resources, the origin and production Urban Sci. 2018, 2, 61 5 of 13 conditions of the goods and services they offer, minimizing resource use, and recycling capacity), and the impact in the policy arena, and the preservation of the right to the city of its inhabitants and the common good of the city. This aspect also regards the protection of the general interest, public space, and basic human rights such as access to housing.

Materials and Methods
The methodology, aimed at testing the application of the above six democratic qualities, was based on an in-depth 10 case study comparison. Data collection was based on digital ethnography (to collect indicators for the cases and get familiar with them), co-creation sessions with the cases, and an interview with each of the cases. Data were collected in May 2017. Data analysis combined qualitative and visual analysis of data from co-creation sessions and interviews.

Sample
The empirical work departs from a previous mapping of 1000 cases of Collaborative Economy in Barcelona, based on the P2P Value directory on collaborative economy. From these resources, we selected 10 based on the following criteria:

1.
Projects with activity in Barcelona.

2.
Projects based on collaborative production.

3.
Projects with a significant level of activity, rather than in a very preliminary stage.

4.
Projects with a social orientation, meaning closer to the cooperative platform than to the unicorn platform scope.

5.
We selected the cases to ensure diversity, and based on being significantly relevant.

Indicators Criteria
For each dimension, we assessed two variables with three grades of accomplishment.

Analytical Methods
We performed a previous web observation to collect more information about the selected platforms, a co-creation session (5 May 2017), and an interview of the 10 cases, following the case study methodology [22]. Departing from our 10 cases chosen, we designed a co-creation session divided into three steps with three main objectives. In the first part, the participants indicated their evolution in the form of a graph, highlighted milestones, and projected their future evolution. In the second part, each platform actively shared how their approach to each point of the commons star diagram (Figure 1: economic model, social responsibility, knowledge and technological policy, and governance model). Finally, all participants identified the challenges of a collaborative procommon economy in terms of specific needs of the sector, technological demands, and public policy recommendations.

Results: Analytical Framework for the Democratic Qualities of 10 Cases of Collaborative Economy in Barcelona
In this section, we present the analytical framework of the democratic qualities of collaborative economy (Figure 1) applied to 10 cases that we analyzed based on each collaborative economy's performance of the star of commons qualities (El Recetario, SMart IB, Goteo, Katuma, Bdtonline, FreeSound, XOBB, eReuse, Sentilo, and Pam a Pam). See Table 1 for a comparison of the cases on their performance of each of the qualities.

Goteo
Goteo is a crowd/match-funding platform constituted as a foundation. The project started through a collaborative founding investigation in 2010, and the first version of the platform launched in 2011. Currently, Goteo has more than 90,000 users, raising 4 million Euros.
• Governance: As a foundation, the decision-making process is carried by a small group of people. • Economic model: Users pay a 4% commission, but the promoters intend to arrive at 0%. • Technological policy: Software is subject to a copyleft license (AGPL).

•
Knowledge policy: Some platform data are freely downloadable. • Social responsibility: In terms of social impact, all projects which participate in campaigns must define the social responsibility of their actions.

Katuma
Katuma is an Agro-food consumption platform based on commons collaborative economy values. The project was launched in 2017 and was developed by Coopdevs, a non-profit association focused on free and open software to promote social and solidarity economy projects.

•
Governance: A membership cooperative governance is planned.

Bdtonline
Bdtonline is a platform of a time banking association, Associació pel Desenvolupament dels Bancs del Temps (ADBdT), which uses TimeOverFlow software, also created by Coopdevs. The association and software were developed and raised in 2012. Currently, 47 organizations use this platform with 5800 users. One of the main goals of the organization is its usability independently of the characterization of the organization.

•
Governance: Annual assembly, they use Loomio groups as a framework of members' participation.

FreeSound
The project, started in 2005, is promoted by Pompeu Fabra University and has a research group with the objective of gathering free content for educational purposes and research. It was a success, winning prizes from the City Council (2005) and Google (2009). Currently, the platform, which is hosted in a central server, has more than six million registered users and over 400,000 registered sounds.

XOBB
The project, constituted as a cooperative, is the result of matching two research groups from different disciplines, sociology and technology, within Universitat Autonoma de Barcelona (UAB). After the rejection of the national blind association, ONCE, the promoters, with the support of other associations for the visually impaired, got resources from a Barcelona City Council grant to finance the first prototype in Creu Coberta Street. Beacons allow blind people to find information about establishments (e.g., products, offers, and open hours).

•
Governance: Periodic assembly meeting. • Economic model: Everybody could use it for free, but if somebody gets economic profit from the network they must pay for it.  Social responsibility: The project is based on reuse to decrease unnecessary production impact.

Sentilo
Sentilo is a platform to collect data from sensors. It was formed by the Barcelona City Council in 2012 in the framework of the Internet of Things. The proposal was based on the scenario of exponential sensors growth, when a space would be needed with structured information on each sensor system. Ten other cities, such as Terrassa, have subsequently implemented it. The platform, born in 2012, is a project by Setem and XES (two organizations linked to SSE) to promote responsible consumption. A community of volunteers maps the initiatives through a qualitative questionnaire. Currently, the project is in a renewal phase with a revitalization plan to face the difficulty of maintaining territorial community mobilization. At the same time, the promoters want to get a self-managed sustainability funding model, apart from subsidies, and legal independence from Setem.

Curve of Growth and Evolutionary Stages of the Cases
The curve of growth shown in Figure 2 represents the stages of evolution and growth of an organization, with an initial kick-off, deep growth, maturation with stabilization, and the renewal or gradient phase. At the co-creation session, each of the 10 cases positioned themselves on the curve. The cases positioned themselves in various stages on this curve of growth. The majority of them, however, located themselves in a positive stage of their activity.

Case Comparison Analysis
According to the results ( Table 2:

Case Comparison Analysis
According to the results ( Table 2: case comparison between the cases of the commons balance), none of the cases fulfill 100% of the five qualities. However, the majority of them accomplish aspects of the commons star collaborative economy review at a good level. Cases 3 (Goteo), 8 (eReuse), and especially 10 (Pam a Pam) achieve in a holistic approach achieving the majority of commons criteria. Two of these projects (Goteo and Pam a Pam) are in a post-maturation evolutionary stage. The qualities linked to the non-profit economic dimension and open participation in governance are the ones more cases fulfill, while technological decentralization, open data, and inclusion indicators (in these order) are the areas less fulfilled by the cases. The governance and economic model get the best evaluation, but open participation and non-profit organization have better valuation than cooperative governance and transparency, respectively. Overall, Case 2 (SmartIB), which is in the early platform development stage, has accomplished the fewest criteria.

Discussion
According to the application of the framework to the sample of 10 cases, we observe that there is no case which fulfills all of the dimensions, but several modalities of being pro-democratic as a digital platform.
Regarding business models, the majority of the 10 cases studied depart from a grant or public funding model and instead have a grassroots character. Four of the projects were connected to H2020 European funds. The main problem of this model is project maintenance when the economic support ends. Only one of the 10 cases mentioned here was awarded and used the services for entrepreneurship of Barcelona Activa, the Barcelona agency of development.
Regarding governance, several of the cases had the intention to get another legal constitution at the time of the study. The current legal formulas for economic association do not adapt well to commons collaborative economy activity. Several of these cases were provided by institutions, whether universities, such as FreeSound and eReuse with the UPF, or public administrations, as in the case of Sentilo being supported by the Barcelona City Council. Those that were legally constituted did so through an association (the simplest formula bureaucratically), a foundation, or a cooperative. In this sense, some associations (Bdtonline and Katuma, for example) manifested in the interviews the intention to become cooperatives. Others were already in the process of doing so (such as XOBB). We also observed other cases of collaborative economy platforms (such as femProcomuns) that were constituted as cooperatives but were not analyzed in this initial study. If the legal cooperative formula spreads among collaborative economy platform projects, as this investigation has found, we can expect new bonds in the growth of cooperatives [23] and the expansion of the social solidarity economy movement in the city of Barcelona [24].
Regarding technological policies, the majority of cases considered FOSS. At the same time, almost all of them centralized their architecture. In the same sense, with regard to knowledge policies, open licenses were more often extended than open data. Accomplishment of social responsibility criteria in the cases analyzed was not regular. Some cases were highly connected to environmental uses (such as eReuse or Katuma) while other favored social inclusion (such as XOBB). If we assess the 10 cases together, both subdimensions-green and inclusion-were half fulfilled.
Our analysis reflects another relevant issue to consider for future research into the ecosystem dimension of the cases. Collaborative economy has an important presence in Barcelona. More than 1000 cases have been identified as commons collaborative economies (see directori.p2pvalue.eu) [18]. The model is also very adaptable. A total of 33 areas of activity (with a broad range: culture, leisure, shopping, etc.) where the model is present in Barcelona have been identified [10]. Barcelona's collaborative economy has an important ecosystem dimension. This phenomenon links with the high number of social innovation practices that have a great tradition in the city [25] and shows the role of citizens in its transformation [26]. This is the case of the collaborative economy platform Katuma (one of the studied cases), for example, which is a potential tool to scale the activity of agroecology cooperatives that have been in Barcelona for over three decades [27].
The 10 cases analyzed showed different levels of connection with the Social and Solidarity Economy (SSE) and Digital Commons framework, network, and values. On the one hand, Goteo was the strongest project in the Digital Commons area. On the other hand, Pam a Pam was the most mature project with the SSE framework in terms of digital platform.
Despite the strong ecosystem, the majority of initiatives start but remain at initial stages, as a fabric of ideas and training, or kick off and grow to a certain level of satisfactory activity. Frequently, there is neither the expectation nor the intention to scale largely. The 10 cases in our sample positioned themselves at a developmental or mature position in the curve of growth, even if they were not considered "mainstream" or established with the big public. This is consistent with the results of the P2P Value investigation over a sample of 300, which pointed to a normal distribution of "success" (many medium cases), instead of a power law distribution with few very successful and the majority unsuccessful [28].
To sum up, our investigation shows that, beyond the controversial and unethical unicorn economy platforms, an alternative model of collaborative economy exists based on democratic qualities of procommon. The nature of these procommon alternatives is connected to the development of the platforms based on the principles of cooperativism. Nevertheless, the main challenge of these procommon collaborative economy projects is their scalability and sustainability.
Regarding future research, even if this study has allowed testing a framework to evaluate the qualities of sustainability and pro-democratization collaborative economy platforms, we consider it necessary to conduct a new investigation. It would, on the one hand, contemplate a broader sample of cases and, on the other hand, cosnider platform projects with different characterizations, from unicorn platforms to procommon platforms, passing through hybrid projects. This new research should provide a broader view of the key aspects of each of the approaches and the pathways of connection and learning between them.
