Firm size, business experience and export intensity in SMEs: A longitudinal approach to complex relationships

The objective of the paper is to test the effect of firm size and business experience on export performance. In fact, despite a growing number of empirical studies, the question of the relationship between these variables is not clearly established. This research aims at contributing to a better understanding of these complex relationships with a special focus on small and medium-sized enterprises (SMEs). The authors develop a general model and test it using a sample of Italian manufacturing firms that spans the 1997–2001 period. Combining a time-series with a cross-sectional analysis, they use an econometric model in order to test the relationships. Their findings provide a strong support for both relationships. The results show that it is not business experience per se which is important but that it is the relative change in experience that truly impacts upon export performance. The model also reveals that industry effects are relevant.     

An international agreement with full participation to tackle the stock of greenhouse gases

Greenhouse gas emissions build up an atmospheric stock which depreciates over time. We identify weakly renegotiation-proof equilibria with full participation in a game of international emission reduction. Treaties are easier to reach for long-lived than for short-lived gases.

Interest on Reserves and the Flexibility of Monetary Policy in the Euro Area

This paper shows that remunerating required reserves can increase the flexibility of monetary policy. The remuneration at the current policy rate implies constant net marginal interest costs of holding required reserves. This allows the central bank to change the policy rate also within a reserve maintenance period without inducing a problematic reserve shifting on behalf of the banks. In the euro area, required reserves are remunerated at an average rate. Therefore, the way in which reserves are remunerated has to be changed in order to make use of the advantage of a higher flexibility of monetary policy.     

The Fuzzy Front End of New Product Development for Discontinuous Innovations: A Theoretical Model

The fuzzy front end of the new product development (NPD) process, the time and activity prior to an organization's first screen of a new product idea, is the root of success for firms involved with discontinuous new product innovation. Yet understanding the fuzzy front‐end process has been a challenge for academics and organizations alike. While approaches to handling the fuzzy front end have been suggested in the literature, these tend to be relevant largely for incremental new product situations where organizations are aware of and are involved in the NPD process from the project's beginning. For incremental new products, structured problems or opportunities typically are laid out at the organizational level and are directed to individuals for information gathering. In the case of discontinuous innovations, however, we propose that the process works in the opposite direction—that is, that the timing and likelihood of organizational‐level involvement is more likely to be at the discretion of individuals. Such individuals perform a boundary‐spanning function by identifying and by understanding emerging patterns in the environment, with little or no direction from the organization. Often, these same individuals also act as gatekeepers by deciding on the value to the organization of externally derived information, as well as whether such information will be shared. Consequently for discontinuous innovations, information search and related problems/opportunities are unstructured and are at the individual level during the fuzzy front end. As such, the direction of initial decisions about new environmental information tends to be inward, toward the corporate decision‐making level, rather than the other way around. In order to cope with the special and complex nature of decisions made at the fuzzy front end of NPD for discontinuous innovations, this process is detailed as a series of decisions occurring over three proposed interfaces: boundary, gatekeeping, and project. The difference between each interface lies in the nature of the decisions made: At the boundary and gatekeeping interfaces, the primary impetus is individual‐level decision‐making; at the project interface, decisions occur at the organizational level. By articulating these processes in the form of a model, we achieve two objectives: (1) We outline a more detailed and comprehensive approach to understanding the nature of the front‐end decision making process for discontinuous innovations; and (2) we detail specific propositions for future research on each stage of the process.     

Mountain bike tourism in Austria and the Alpine region – towards a sustainable model for multi-stakeholder product development

This paper interrogates the polarized and heated discussions about mountain bike tourism in Austrian forests, with several organizations favoring permitting biking on all forest roads, using claimed tourism development opportunities, while other stakeholders including hikers, hunters and landowners wish to restrict development. An international literature review on the value and impacts of mountain biking shows that both sides have oversimplified complex cases. The paper draws on 12 in-depth interviews with Austrian tourism destination and mountain bike experts to find ways forward. Results suggest that in Austria, bike tourism will increase in the future, supported by new bike technology, including electric bikes and new hand-held route information technology. It notes the complexity of the market for mountain and other forms of cycle tourism, and the pressing need to create not more trails but more sophisticated tourism products, including appealing and well-maintained trails plus attractive leisure infrastructure (bike rental, service and repair facilities, attractive localities, accommodation suited to the mountain bikers’ needs, etc.). Collaborative planning with all stakeholders, better trail construction standards adapted to differing preferences, needs and environmental conditions as well as clear standards for monitoring are prerequisites of an Austrian strategy for sustainable cycle tourism development and management, which can be replicated elsewhere.     

Aufstieg der Semiöffentlichkeit: Eine relationale Perspektive

In this theoretical contribution we reflect previous attempts to re-conceptualize the public sphere in a digital era and suggest an alternative perspective: to combine public sphere theory with relational sociology. By doing so, we are better able to understand the transformation of public spheres as a transformation of communicative relations within public spheres.In the past decades, scholars have addressed these transformations by mainly two strategies: a fragmentation and/or a conceptual extension of the public sphere. The first approach, fragmenting the public sphere concept, deals with the question if and how new publics emerge as a result of digital communication tools. It sees the “remnants” of the mass-mediated public sphere as only one of many new public spheres—and not necessarily as a central one in network societies, resulting in a differentiation of new types of public spheres. The second approach, extending the public sphere, focuses mainly on how digital communication technologies change traditional, mass-mediated publics. In this view, the multiple forms of digital communication add to the mass-mediated public sphere: The public sphere now contains the diversity of mass media, the Internet and mobile media. Thus, the public sphere now encompasses all forms of mediated communication, resulting in more complex structures.This contribution argues that the current “relational turn” promises new avenues to understand what changes within public spheres in a digital era. Relational sociology shares its roots with network theories, but it focuses on the edges, the links between nodes, thereby overcoming the nodocentrism of network approaches. Relations are seen as the constitutive elements, molecules of society and public spheres. In a relational paradigm, all analysis of public spheres begins with social relations. This means that it is no longer necessary to define a new “space” for new forms of interaction, such as virtual public spheres, digital public spheres or networked public spheres. Instead, we add new forms of interactions and social relations that constitute public spheres. In this view, social relations within public spheres are diversified, not public spheres as such. The argument continues with a discussion of different types of social relations: chains, triads and categorical pairs.In connection with public sphere theories, social relations can be differentiated as public, semi-public and private. Based on the notion that public communication, whether personal or impersonal, always requires an addressee beyond the closest circle of friends, family and acquaintances, public social relations are defined as relations containing strangers. In this perspective, private social relations take place between social entities that know each other and are shielded from strangers. Public social relations, on the contrary, take place between social entities that are (still) strangers to each other and, in principle, open for participation. If private social relations must not encompass strangers, and public social relations must encompass strangers, then semi-public social relations can encompass strangers: either as addressees or only as observers and otherwise passively involved social entities. Thus, semi-public social relations are delimited, as are private social relations (not open for everyone), but the demarcation is permeable for strangers. The public sphere contains only specific social relations based on communication: those that can encompass strangers and those that must encompass strangers. Thus, we can define the public sphere as a dynamic configuration of social relations of various types that encompass strangers.It is argued that with the waning dichotomy of public and private, semi-public social relations are a major consequence of the current transformations within public spheres. In connection with the different kinds of relations introduced above, we then discuss private, semi-public and public chains, triads and categorical pairs, illustrating them with examples.A focus on communicative relations that constitute public spheres allows to understand—across micro, meso and macro perspectives—how different platforms and their affordances impact the formation of social phenomena, e.?g., how protest publics emerge from low-threshold interactions and below the radar of mass media. Semi-public relations are key: Public spheres are no longer built only on addressing as many strangers as possible (in the form of an audience), as was and is the modus operandi of mass media. Social media enable individuals to communicate beyond their private networks: friends of friends, weak ties bringing visibility, relevance, reach for information from non-redundant, socially distant sources. Semi-public communicative relations enable the formation of protest groups from Facebook groups of friendship circles (e.?g., the German right-wing nationalist movement Pegida), proliferate “fake news” and stimulate public discourse through hashtags (e.?g., #metoo). A relational perspective of semi-public communication allows for a better understanding of viral phenomena. Due to the current transformations of the public sphere, we do not only experience more semi-public communication, but a diversification of semi-public communicative relations.     

Global financial liberalisation GATT,EC and OECD approaches

In view of increasing worldwide economic integration, effective multinational agreements are urgently needed to improve the functionality, efficiency and stability of international financial operations. This article confronts theoretical characteristics of a desirable global financial concept with the actual liberalisation approaches of different organisations.
