The present study aims to identify the determinants of the capital structure of restaurants firms in Portugal, as well as to analyze the application of capital structure theories in those companies.

In order to reach the objectives, a sample of 400 companies belonging to the restaurant sector was used. The analysis was carried out between 2008 and 2017, and multiple linear regression, based on panel data, was applied.

The obtained results allowed to verify that the considered variables have different effects on the capital structure of the companies under study and that the restaurant sector partially applies the trade-off, pecking order and signaling theories.

This chapter analyses the efficiency of African airlines using a two-stage network DEA (Data Envelopment Analysis) model. Network DEA models usually take into account the production process with intermediate inputs derived from the first stage and a second stage that departs from it. This fundamental feature enables one to view the airline production process as a carry-over activity. The analysis covers the 2010–2013 period. The relative efficiency ranks are presented and policy implications are derived.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Paul Samuelson was attracted to the irregular economic development pattern of some South American countries because of the links between economic performance and political factors. He discussed the influence of “populist democracy” on Argentina’s relative economic stagnation, which, he argued in the 1970s and early 1980s, served as a dangerous paradigm for the American economy under stagflation. Stagflation phenomena marked the end of Samuelson’s “neoclassical synthesis.” Moreover, he applied his concept of “capitalist fascism” to deal with military dictatorships in Brazil and (especially) in Chile. The Brazilian translation of his Economics in 1973 brought about a correspondence with Brazilian economists about the “fascist” features of the regime. The main variable behind the South American economic and politically unstable processes discussed by Samuelson was economic inequality, which became also a conspicuous feature of the American economy since the adoption of market-based policies in the 1980s and after.

When examining anecdotal evidence of migration processes, from historical and geographical perspectives, stories of individual immigrants that became successful entrepreneurs in the host country are commonplace. These narratives help individualize and romanticize the usually crude statistics of the increasingly common population movements across political borders. They also serve a number of purposes within the ethnic community, most of them associated with the creation and nurturing of the group's social capital. This critical ethnic resource has been consistently shown to provide significant benefits to immigrant communities, particularly in environments with higher levels of perceived risk (e.g., Portes, 1998; Martes & Rodriguez, 2004).

Digital transformation, and the use and pervasiveness of social media in particular, have changed society. Politicians and political institutions increasingly use social media channels; hence political communication is changing as well. Continuous availability through smartphones and other devices has not only led to more information exchange between political and public actors, but also lobbyists, who classically communicate remotely, are also starting to respond to these changes and use tools such as Twitter, Facebook and the like. Against this background, this study provides insights into the effects of digital transformation, especially social media, on lobbying in Germany. Data were gathered from 15 interviews and seven focus groups with lobbyists and political decision makers in Berlin. The analysis shows that digital lobbying operates within a novel logic, due to the public context of social media. It is the human element that becomes the decisive factor in digital lobbying due to the social aspect in social media. Accordingly, investigating digital lobbying is critical to establish implications for theory and for practice.
