The purpose of this paper is to investigate firm strategies and the exertion of market power in the brewing sector in Brazil following a merger between the two largest brewers (Brahma and Antarctica) that created Ambev and given that the existing literature is inconclusive on this subject

In this study the authors apply cointegration analysis to price series of beer brands. The authors use the reduced form vector error correction (VEC) model to measure the price responses of beer brands in terms of direction, magnitude and speed. The authors use monthly retail prices for the primary brands of beer in the city of São Paulo, Brazil's largest consumer market. Specifically, the authors use two sets of retail prices, one from bars (the main point of beer sales, with roughly 50% of market share) and another from supermarkets. The series range from 1994 to 2014, depending on the brand.

This study indicates that Ambev's two major brands (Skol and Brahma) behave as market leaders, while its third brand (Antarctica) has been used to challenge the low-price competitor (Nova Schin). The authors also found evidence that the pricing policies of Brahma and Antarctica have changed toward cooperation following the creation of Ambev.

The main limitation of this article is that the authors only had access to retailer data. As the merger involved brewers, the authors would ideally use manufacturer beer prices in their econometric analysis. However, the consistency of our results suggests that retailers have been passively transmitting brand strategies launched at a manufacturer level.

As the dominant firm created following the merger of the two largest brewers appears to use one of its brand to restrict entry of competitors and the premium brands to enjoy high profits, consumers tend to be harmed by high beer prices and lack of options. Furthermore, small and medium-size companies cannot grow due to entry barriers created by the dominant firm.

This paper is the first to apply cointegration analysis to examine the effect of mergers on pricing strategies. The robustness of this study suggests that this approach could be used for antitrust agencies to monitor post-merger strategies.

In May 1999, the CEO of this company (the largest brewer in Brazil) is contemplating a bid for Antarctica, the second-largest brewer in Brazil. The primary motives are to exploit economies of scale and other synergies and to prevent other competitors (mainly foreign multinationals) from acquiring the firm. The tasks for the student are to value the target and buyer, propose an exchange ratio of shares, and generally design the terms of the transaction.

Tourism in Antarctica is rapidly growing and diversifying, which raises concerns about its impacts and the robustness of the current regulatory regime. Focusing on the analysis of past developments and trends of Antarctic tourism, this paper aims to describe the future opportunities for tourism in Antarctica.

Using literature on the recreation opportunity spectrum (ROS) and ecotourism opportunity spectrum (ECOS), the paper analyzes the future opportunities of Antarctic tourism and the key factors that determine the window of opportunity for Antarctic tour operators.

The analysis shows that tourism opportunities in Antarctica are defined by a combination of factors, which the authors integrate into an Antarctic tourism opportunity spectrum (ATOS). The paper argues that the opportunity settings for tourism in Antarctica vary from operations of increasing scale and efficiency to the continued development of smaller scale niche products, both of which will continue to diversify and drive the development of tourism in Antarctica.

The paper is an attempt to transfer the concept of ROS, originally designed for the operational level of national park management, to the more strategic level of tourism trends in Antarctica. The research findings are based on stakeholder interaction within a limited number of countries.

The paper is a potential source of information and advice for policy makers and managers of Antarctic resources, as well as scholars interested in Antarctic tourism issues.

The paper contributes to the ongoing debate on the regulation of tourism in Antarctica.

The continent of Antarctica consists of 14 million km², roughly equivalent to the whole of South America, and is of immense interest to humanity, in particular to the countries of the Antarctic Treaty. The Antarctic continent is the continent of superlatives: it is almost isolated from the rest of the continents, and is severely cold, windy, and dry. In winter, the Antarctic area increases to nearly 32 million km², because of formation of a 1,000km wide ice‐belt. The average depth of ice on the continent is in the order of 2,000m, and in the transantarctic region this depth is 4,800 meters. Antarctica is the biggest sweet water reservoir of the planet earth. Icebergs are common and huge ones (190km in length and 130km wide) have also been observed. The minimum temperature recorded (–89.2°C) at Vostok (Russian base) on 21 July 1983 is also the minimum recorded environmental temperature on the planet earth. Because of extreme temperature variations the Antarctic winds have high velocity. The environment is very dry and at the center of the continent the dryness is of the same magnitude as in the driest desert anywhere on the planet. This is the only uninhabited continent of the planet, except for some 50 research bases which cover an insignificant area located on the continent and the Antarctica Peninsula. Because of its economic, strategic, geopolitical, scientific, meteorological, and oceanographic importance and possible exploitation in the future, Antarctica has been attracting greater attention every day. Antarctica is basically concentrated around the South Pole and it touches the Atlantic, Pacific, and Indian Oceans. Brazil, in common with many other nations, has geopolitical interests and in untapped mineral deposits (considerable deposits of coal, petroleum, gas). In the south, where the Atlantic, Pacific and Indian Oceans meet, the cold water of Antarctica is the habitat housing hundreds of species of sea life. Unrestricted and unbalanced exploitation of Antarctica could cause changes in the meteorological and oceanographic balance. In the present paper, the Brazilian Antarctic Program, and summarized results of studies of Antarctic soil, rocks, and sediments are reported.

The international tourism options have been enriched due to several factors: new transport technology, more flexible legislation, the globalization process, and political openness regarding some areas dominated by dictatorship regimes. Antarctica is one of the new possibilities for adventure and ecological travel. It is the wildest, most well‐preserved and most isolated continent on the planet. About 10,000 tourists can appreciate its dazzling landscapes each austral summer and tourism operations have increased considerably in the region during the 1990s. This article presents a history of travel to Antarctica, an analysis of the tour operators and of the Antarctic Treaty on tourism, and reports an experience on board one of the cruise ships in the Antarctica Peninsula.

This paper aims to draw on Ostrom’s commons theory to analyse the governance regime of Antarctic as a commons institution. Antarctic is a peculiar territorial space on Earth, which due to its unique characteristics constitutes a global common resource that very much resembles outer space resources. On these grounds, the paper highlights successful, and less successful, arrangements developed in the Antarctic commons to be considered as a blueprint or roadmap towards the governance of outer space resources as a commons.

The paper uses first, the social-ecological system (SES) framework to outline the characteristics of Antarctic as a commons institution, and second, Ostrom’s design principles to assess the commons institution of Antarctic. The Antarctic commons institution is used next, as an analogy to reflect on the challenges outer space global resource face and the way it could be managed.

The paper concludes that Antarctic enjoys a functional, credible and successful commons institution that should reinforce the twofold governance structure it exhibits. Similar cases of global common resources, such as these of outer space, that seek to establish a similar commons institution should take into account issues related the benefits spectrum and the credible commitment of actors to engage in different levels of the governance regime. What matters is not necessarily the form of the regime but rather how the commons as an institution functions, whether it fulfils the needs and interests of the driving actors and, on these grounds, how credible these arrangements are in the eyes of the committed members.

Both Antarctica and outer space are rather unique cases and domains of multiple resources.

The paper provides an analogy to consider sustainable appropriation of global resources (“global commons”) for peace and prosperity to all.

The paper is original, in the sense that according to the best of the authors’ knowledge, no published work has identified Antarctic as a commons institution or has used the aforementioned methodologies to analyse Antarctica as a commons and to employ their findings in providing directions for the design of appropriate governance frameworks for other resources that exhibit the characteristics of global commons, such as these of the outer space.

Antarctica, the highest, coldest and windiest of all continents is also the least known. Although initial discovery and exploration began with Captain Cook in the 18th century, substantial investigation began only in the 20th century. 1956 — the start of the International Geophysical Year — marks the major turning point for interest in Antarctica and the beginning of a continuing growth in Antarctic information. Increasing international interest in Antarctic resources, conservation, politics and science is providing a much wider demand for environmental information of all types.

This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end‐users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

The purpose of this paper is to design, build and test a low power high frequency (HF) transmitter that can be received by the Super Dual Auroral Radar Network (SuperDARN) radar installed at SANAE IV, the 4th South African National Antarctic Expedition Station. It is proposed that it may be possible to do propagation studies using the radar and the fixed frequency, ground-based HF transmitter beacon. Interpretation of the measurements can be used to study the ionosphere, especially Travelling Ionospheric Disturbances, which are signatures of atmospheric gravity waves.

In the absence of the actual deployment of the HF transmitter beacon in Antarctica, extensive simulations have been done to evaluate the expected performance of the transmitter in relation to the SuperDARN. A field trial has been executed between Hermanus (34.4241° S, 19.2247° E) and Pretoria (34.0558° S, 18.4589° E) in South Africa. In future, the beacon will be placed at the South Pole with its antenna radiating towards SANAE IV.

The HF transmitter conforms to the power and frequency stability requirements both during propagation tests conducted between Hermanus and Pretoria, as well as when the device was exposed to temperatures that ranged from +40°C to −45°C in a thermal chamber. Propagation in Antarctica is expected to differ from the field tests conducted due to the differences in density and dynamics of the polar ionosphere, compared to the mid-latitude ionosphere.

Space weather research, including forecasting atmospheric gravity waves and determining the expected electron density profile of the ionosphere, is of great scientific interest. The data received from the HF beacon can be used to study and characterize the ionosphere of the region between the South Pole and SANAE IV. Parameters of the ionosphere, such as electron density, geomagnetic storm effects, ionospheric motions and sky wave propagation paths will be better understood from analysing the signal received from this transmitter after it has been reflected and refracted by the ionosphere.

In this final chapter, we explore the ever-evolving 21st century landscape where ethics drive community development toward resilience and progress.
