In this work, the authors analyze the dynamic interdependencies between military expenditures and the real economy for the period 1970–2018, and the authors' approach allows for the existence of dominant economies in the system.

In this study, the authors employ a Network General Equilibrium GVAR (global vector autoregressive) model.

By accounting for the interconnection among the top twelve military spenders, the authors' findings show that China acts as a leader in the global military scene based on the respective centrality measures. Meanwhile, statistically significant deviations from equilibrium are observed in most of the economies' military expenses, when subjected to an unanticipated unit shock of other countries. Nonetheless, in the medium run, the shocks tend to die out and economies converge to an equilibrium position.

With the authors' methodology the authors are able to capture not only the effect of nearness on a country's military spending, as the past literature has documented, but also a country's defense and economic dependencies with other countries and how a unit's military expenses could shape the spending of the rest. Using state-to-the-art quantitative and econometric techniques, the authors provide robust and comprehensive analysis.

This chapter looks at web-radio and podcasting in Greece, exploring their past, current status and considering possible futures. The analysis begins from broadcast radio in order to explore the, sometimes complex, relationships between traditional and new digital formats, particularly as these exist in an already financially and politically challenging terrain. Some tensions are revealed as the author, via primary and secondary research, navigates the radio landscape in a country that is now emerging from a long financial crisis. As there is very little writing on Greek Podcasting, this chapter aims to provide a snapshot of what currently exists and to suggest possible functions and creative avenues for it in Greece moving forward.

Since the 1980s, planning public spaces for leisure walking is largely linked with economic and cultural objectives. Parallel to this tendency and the priorities of local authorities on barker public space projects, inhabitant’s associations, that grow up after the 2000s, propose new ways of visiting the city through collective walks. Drawing on the example of the Atenistas group, and based on the discourses of its founders, its presence on social media and the narratives of participants, the purpose of this paper is to question the emergence and function of new forms of urban walking that joggle between tourism, social exchange and act of citizenship.

The case study is based on personal semi-directive interviews with organisers and participants at “Atenistas Open Walks”. It is also based on interviews that have been held with architects and urban planners within technical services of the municipality of Athens as also as within private sector’s structures.

First insights from the study question pedestrianisation as a dominant urban planning tool towards animated street life and performant local economy. Contrary to the traditional top-down approach in Athens’s public space planning which uses pedestrianisation or land management to re-invest on the city centre, Atenistas Open Walks reveal the existence of alternatives ways of a re-engagement with city values and history. People search to explore the city by themselves and re-trace their proper itineraries (and ways of seeing the city) by outpassing official discourses on the decline, the success, the dangerousness or the beautifulness of certain neighbourhoods. Consequently, walkers constantly nourish their will to better understand the city. Public space experience outpasses morphological or functional issues. The act of walking with others in the city willing to explore places and to exchange on this experience, confront people with different narratives and trajectories and can momently be a strong factor of social cohesion and activation of public space with significant impacts on local economy. Walking collectively can emerge, in this way, as a counter model of public space planning capable of revitalise not only touristic activity, but also citizenship.

The study questions dominant discourses that link urban liveability and touristic attractiveness of urban centres with recreational events and streets’ pedestrianisation projects.
