Three themes permeate most discussions of Australia’s relationship with Europe. The first is that relations are marked by extreme asymmetry. On one side there stands a large and economically powerful group of states, increasingly organised within the European Union (EU); on the other, a middling power that belongs to no regional bloc and possesses limited international clout. The second is that Australia’s relations with Europe are largely driven by trade issues, especially issues in the agricultural sector. And the third is that Australia’s close bilateral links with Britain are still a central feature of its European policy.
Phylodynamic models can be used to estimate diversification trajectories from time-calibrated phylogenies. Here we apply two such models to phylogenies of non-avian dinosaurs, a clade whose evolutionary history has been widely debated. Although some authors have suggested that the clade experienced a decline in diversity, potentially starting millions of years before the end-Cretaceous mass extinction, others have suggested that the group remained highly diverse right up until the Cretaceous-Paleogene (K-Pg) boundary. Our results show that model assumptions, likely with respect to incomplete sampling, have a large impact on whether dinosaurs appear to have experienced a long-term decline or not. The results are also highly sensitive to the topology and branch lengths of the phylogeny used. Developing comprehensive models of sampling bias, and building larger and more accurate phylogenies, are likely to be necessary steps for us to determine whether dinosaur diversity was or was not in decline before the end-Cretaceous mass extinction.
The 2007 – 2008 financial crisis has been the subject of many articles, books, movies and even a theater play. We take you for a walk along Wall Street, pointing at some aspects of the story that touch our personal experiences and interests. We look critically at some of the main underlying causes. Besides political blindness, we highlight the unbridled growth of power of relatively small groups of investment bankers and how these brought financial institutions to (and in some cases beyond) the edge of bankruptcy. We expose some of the over-complicated financial instruments together with their astronomical volumes traded. We also look more critically at the role played by quants (financial engineers) in general and mathematicians in particular. What is the truth behind “The formula that killed Wall Street”? An important aspect concerns early warnings not heeded to. In summary, this is a chapter on greed, power, complexity, volume and stupidity.
Energy supply security has been a crucial energy policy issue for CEE countries at least since the natural gas supply disruptions of 2006 and 2009. This book argues that energy security plays a generally more important role within the CEE region than issues related to climate change. However, this chapter evaluates the interplay between ideas, institutions and the material nature of energy systems in the development of energy policy. In doing so it also highlights the social construction of energy security, demonstrating that energy security is not self-evident or correlated within the CEE region with dependency on energy imports from Russia. Individual CEE countries perceive energy supplies as a security issue to a different extent, identifying the source and extent of insecurity or risk differently, and supporting different policy responses as a result. While some countries, for example, Hungary or Bulgaria, have tended to perceive Russian energy as a means to guarantee energy security, others – most notably, Lithuania and Poland – consider energy security to be one of their main policy issues and imports of Russian energy as one of the main threats to this.
This chapter focuses on the impact of CEE countries on the development of climate and energy policies at the EU level. It is argued that states in the region demonstrate some shared preferences and utilise regional groupings to promote these at the EU level. The chapter discusses the contribution of CEE countries to the development of EU policy – such as Polish efforts to create an ‘Energy NATO’, CEE countries’ efforts to improve energy security following the 2006 and 2009 gas crises, the 2014 Energy Union, and the reaction to the full-scale Russian invasion of Ukraine in 2022. The chapter argues that the security dimension was given priority by CEE countries at the EU level. They contributed to placing energy security on the EU’s agenda during accession negotiations and the immediate post-accession period; however, their preferences were often not shared by older members. It was the 2006 and 2009 gas supply disruptions that shifted the focus towards energy security in the region, and at the EU level. In 2022 the EU’s dependency on and vulnerability to high levels of energy imports from Russia were brought into sharp focus.
ERISA strictly regulates fiduciaries. While ERISA’s fiduciary rules were abstracted from state trust law, several important departures exist. Congress adopted a broad functional definition of fiduciary so that all decision makers – not just asset managers (traditional trustees) – can be held accountable. Importantly, however, decisions by employers respecting the design, establishment, or modification of an employee benefit plan are not fiduciary acts for they do not implicate program management (the so-called settlor versus trustee distinction). ERISA specifies a stringent set of fiduciary duties, including four major obligations: loyalty; prudence; compliance with plan terms that do not violate ERISA; and (generally) investment diversification. Plan provisions that would excuse fiduciary breach (exculpatory clauses) are explicitly barred. In addition, certain transactions involving insider dealings with the plan are prohibited regardless of fairness or whether loss ensues. Fiduciary liability with regard to participant-directed investments has received careful attention from both courts and regulators and is specially examined in the chapter.
The Romans had to cope with uncertainty and, in part, did so through a shared set of knowledge and practices, which this chapter calls a risk culture. These ways of coping contained a lower level of individuality, consciousness or reflexivity than Beck’s modern Risk Society. There was also no simple divide between lay and expert knowledge. The Roman world exposed its inhabitants to a variety of risks but the accumulated experience of coping with these represented a mutual way of mitigating the dangers.

Tropical mountain regions are characterized by complex and mostly resident avifaunas with many small-range species and a high turnover of species across mountain ranges. On a global scale, tropical mountains show an over-representation of both recently-diverged and ancient species, making them both cradles and museums of biodiversity. Tropical mountains are characterized by slight seasonality, and local habitat gradients can be maintained over a long time. The highest levels of diversification and local endemism are found in the tree-line zone. However, a few avian families also diversified in the alpine zone. Here, many species forage by probing for invertebrates in the ground and in matted vegetation, and many species also exploit carbohydrate foods, including nectar. In an environment with few large insects, co-adapted networks of nectarivorous birds and plants play an important role. There is little published evidence of avian population changes that can be related to recent global warming, as the night-time freezing conditions in open landscapes make it difficult for arboreal vegetation to expand upslope. As glaciers melt, we should expect changes in the rich avifauna of the many periglacial Andean wetlands. Re-visits to well-documented study sites in tropical mountains are now needed to evaluate the amount of change.
In response to survival challenges, small farms in the United States undertake decisions to minimize downside risk or maximize gross revenue. Using primary survey data of small farms in Tennessee, we examined farmers’ strategic decisions on specialization or other forms of diversification and estimated the impacts of these decisions on farm financial performance. We found that farmer’s age, farmland holdings, use of a smartphone in farm-related activities, and off-farm work significantly influenced these strategic decisions. Our multinomial endogenous switching regression estimates suggested that small farms could attain significantly higher performance, around 45% higher gross farm income and a 30% higher return on assets, by adding alternative on-farm enterprises.
This study identifies evidence of the influence of diversification and leverage on the financial performance of Brazilian and Mexican family businesses. It analyzes 102 Brazilian and 71 Mexican publicly traded family companies. Data analysis uses ordinary least squares regression in Stata. The results indicate that Brazilian family businesses have a higher return on assets when diversifying their products or services. When diversifying international markets, Brazilian companies present a lower return on assets and return on equity. For Mexican companies, international diversification derives a higher return on assets and return on equity. In addition, results show that leverage moderates the relationship between diversification and performance both for Brazilian and Mexican family businesses. The study contributes to the current literature by investigating that diversification improves business performance and that leverage is a significant element in intensifying the benefits of this strategy in the performance of family businesses. The study also emphasizes that diversification can be useful to address market difficulties and imperfections in unstable scenarios, such as when it is targeted to planned performance and considers financial conservatism in family companies.
This chapter discusses the impact of the 1966 tobacco embargo and the war of liberation, 1972–1980 on tobacco farming landscapes in Southern Rhodesia. It integrates the political and economic aspects of the Unilateral Declaration of Independence of 1965 into ecological narratives towards understanding how the pressures of economic sanctions and war prompted new patterns of agrarian development and conservation practices in tobacco farms that had an impact on the environment and landscapes.
Discusses the origins of the Armstrongs and Vickers firms and their shifts into armament production. In trying to make domestic sales Armstrongs and Vickers encountered three main challenges in dealing with the British Government. First, the primacy of laissez-faire ideology within the Government, especially in the Treasury and the Foreign Office and Diplomatic Service. Second, the class prejudices of the southern elite dominating the British Government. The governing elite’s distain for trade made it difficult for armament firms to get any help, though the Admiralty and sometimes the War Office needed their products and so dealt with them. Third, departments such as the Foreign Office and Diplomatic Service were disinclined to deal with trade, preferring to focus on high politics. In response, Armstrongs and Vickers developed strategies for the domestic and international markets: building and maintaining relationships with British elites, including through exchanging personnel with the government and supplying intelligence; building and maintaining relationships with foreign elites, including using agents for diplomacy, and bribes to facilitate sales; excluding competitors from the domestic market; if exclusion failed, then cooperating and colluding with other armament firms; diversifying when sales were scarce; providing finance to secure international sales; and innovating to generate sales.
It is often the case that one can choose a mix of alternative options rather than have to select one option only. Such an opportunity to diversify may blunt the risk involved in all-or-none choice. Here we investigate repeated investment decisions in two-valued options that differ in their riskiness, looking for the effects of recent decisions and their outcomes on upcoming decisions. We compare these effects to those evident in all-or-none choice between the same risky options. The “state of the world”, namely, the likelihood of the high versus the low outcomes of the options, is manipulated. We find that aggregate allocation diverges from uniformity (i.e., from 1/n), and is sensitive to outcome probabilities, with the pattern of results indicating reactivity to the outcome of the previous decision. Round-to-round dynamics reveal that the outcome of the previous decision has an effect on the subsequent decision, on top of inertia; the aspects of the outcome that influence the next decision indicate an effect of a missed opportunity, if there was one, in the previous decision. Importantly, recent outcomes have a similar effect in diversification decisions and in all-or-none choice.
As the market for fine-wine investing matures, basic questions of portfolio strategy remain unexplored. I evaluate how adding fine wine from the superstar châteaux of Bordeaux's Right Bank might complement the traditional focus on the five first-growths of Bordeaux's Left Bank. Fundamentals for the Right Bank's superstars are attractive: they produce roughly an order of magnitude less, face different production conditions, and receive equally impressive critical reviews. However, they receive far less attention than their Left Bank counterparts. To examine returns over the long run, I hand-collected 10,885 prices for eight wines from an archive of 391 Sherry-Lehmann catalogs, a New York City retailer, which began at the end of Prohibition. Using these historical price records, I compare the real returns from investing in the five Premier Cru to a portfolio that adds three superstar châteaux from the Right Bank: Ausone, Cheval Blanc, and Petrus. I find the geometric-average annual return was 6.78% in real terms from 1938 to 2017 for the joint portfolio, less than 0.01% different, but with better risk-reward as measured by the Sharpe ratio. Additionally, I find the life cycle of aging is substantially different across the two Banks, which could provide further diversification benefits for the strategic investor.
Africa is a massive continent. One could fit all of Western and Eastern Europe (including the UK), India, Japan and China, and the United States into the continent, and still have space left. Africa, of course, has far fewer people. In 2021 an estimated 1.4 billion people lived on the African continent. The combined number for those other countries was a startling 3.7 billion people.
This makes Africa a land-abundant continent. In other words, Africa has a low labour-to-land ratio – there are about 46 people for every square kilometre in Africa as compared to 150 people, on average, in those other regions. The numbers for China (153), Western Europe (174) and India (464) are much higher.
This high land–labour ratio is not a new phenomenon. Africa has historically also had an abundance of land relative to the number of people who can work it. As we will see in this chapter, it has shaped the types of production systems and institutions that developed on the continent.
This paper proposes a shift in the valuation and production of long-term annuities, away from the classical risk-neutral methodology towards a methodology using the real-world probability measure. The proposed production method is applied to three examples of annuity products, one having annual payments linked to a mortality index and the savings account and the others having annual payments linked to a mortality index and an equity index with a guarantee that is linked to the same mortality index and the savings account. Out-of-sample hedge simulations demonstrate the effectiveness of the proposed less-expensive production method. In contrast to classical risk-neutral production, which revolves around the savings account as reference unit, the long-term best-performing portfolio, the numéraire portfolio of the equity market, is employed as the fundamental reference unit in the production of the annuity. The numéraire portfolio is the strictly positive, tradable portfolio that when used as denominator or benchmark makes all benchmarked non-negative portfolios supermartingales. Under real-world valuation, the initial benchmarked value of a benchmarked contingent claim equals its real-world conditional expectation. The proposed real-world valuation and production can lead to significantly lower values of long-term annuities and their less-expensive production than suggested by the risk-neutral approach.
Although soybean is emerging as an important commercial crop in sub-Saharan Africa (SSA), its productivity on smallholder farms is very low. Soybean requires application of phosphorus (P) fertilizer and inoculation with the right rhizobium strains to achieve optimum biological nitrogen fixation and higher yields. However, subsistence farmers in SSA rarely invest in P fertilizers and inoculants due to lack of knowledge of their use and benefits. Most of the early reports on soybean in SSA have been based on work on research stations; hence, information is lacking on the profitability of fertilizer and inoculant use on smallholder farms in SSA. The main hypothesis of the present study was that the combined application of P and inoculants significantly reduces yield risks and increases P use efficiency and profitability compared with P fertilizer alone under smallholder farm conditions. We analyzed a data set of over 2,800 observations from on-farm demonstrations across Ghana, Kenya, Malawi, Rwanda, Tanzania, Uganda, and Zambia. Soybean yields, the partial factor productivity of P (PFPP), agronomic efficiency of P (AEP), and the value cost ratio (VCR) were significantly improved by the combined application of P fertilizer with inoculants than with P fertilizer alone. Combining P and inoculants increased yields over P alone by 17.3% in Kenya, 21.4% in Zambia, 25.7% in Ghana, 56.4% in Tanzania, and 57.1% in Malawi. However, soil organic matter was an important determinant of yield response and P use efficiency. The VCR increased linearly with increasing AEP in P + inoculant (R2 = 0.829) and less so with P fertilizer alone (R2 = 0.672). Net present values were positive in all countries, indicating that investments in P fertilizer and inoculants will generate profits over time. In order to increase uptake of fertilizers and inoculants among subsistence farmers and make soybean production more profitable, appropriate policies and market incentives need to be created.
The disproportionately low level of equity owned by controllers of dual-class firms can incentivise various behaviours in the way that they manage, or cause to be managed, their firms.With controllers feeling less of the consequences from their actions, controllers may be incentivised to ‘tunnel’ profits from the company, pay themselves high executive remuneration, cause the company to take decisions primarily in the pecuniary or non-pecuniary interests of the controller rather than in the interests of shareholder wealth, pass control to unsuitable heirs, block lucrative takeovers and, when takeovers do occur, extract control premia.Management is entrenched, meaning that when controllers take such actions, the public shareholders cannot change the management team.However, controller benefits may not just harm public shareholders, and certain controller benefits can incentivise actions that are neutral or beneficial to shareholder wealth, such as profitable related-party transactions, the bonding of a visionary founder to the firm, maximising takeover value, taking a long-term approach and risk-taking.A dual-class stock tradeoff exists, and if legal regulatory and market constraints can limit the extraction of pernicious controller benefits so that they are outweighed by benign controller benefits, the structure can be net beneficial for controllers and public shareholders alike.
1. To define economic exposure and its strategic significance for the MNE.
2. To describe the various approaches to manage and minimize economic exposure.
3. To explain the added complexities surrounding economic exposure when MNEs operate multiple business models, following from a high level of diversification.
4. To introduce a new-economy financing tool, namely, crowdfunding, that could be used by resource-constrained MNEs to raise financial resources and to manage potential economic exposure across national borders.
5. To explain the linkages between the MNE’s administrative heritage and its organization of the risk exposure management function, thereby also paying attention to the advent of digital assets.
Catastrophe insurance markets fail to provide sufficient protections against natural catastrophes, whereas they have the capacity to absorb the losses. In this paper, we assume the catastrophic risks are dependent and extremely heavy-tailed, and insurers have limited liability to cover losses up to a certain amount. We provide a comprehensive study to show that the diversification in the catastrophe insurance markets can be transited from suboptimal to preferred by increasing the number of insurers in the market. This highlights the importance of coordination among insurers and the government intervention in encouraging insurers to participate in the catastrophe insurance market to exploit risk sharing. Simulation studies are provided to illuminate the key findings of our results.
