Confronting the threat of nuclear winter

Large-scale nuclear war sends large quantities of smoke into the stratosphere, causing severe global environmental effects including surface temperature declines and increased ultraviolet radiation. The temperature decline and the full set of environmental effects are known as nuclear winter. This paper surveys the range of actions that can confront the threat of nuclear winter, both now and in the future. Nuclear winter can be confronted by reducing the probability of nuclear war, reducing the environmental severity of nuclear winter, increasing humanity's resilience to nuclear winter, and through indirect interventions that enhance these other interventions. While some people may be able to help more than others, many people—perhaps everyone across the world—can make a difference. Likewise, the different opportunities available to different people suggests personalized evaluations of nuclear winter, and of catastrophic threats more generally, instead of a one-size-fits-all approach.     

The implications of empirical data for risk

It is of interest for national governments to assess strategic issues such as natural hazards and anthropogenic threats with some reference to risk, in order to support prioritisation of treatment solutions. With most threats of strategic relevance such as earthquakes, pandemics and terrorism following a distribution in size of events, representation of the risk for a threat as a single frequency–consequence pair is often inadequate as this single pair may exclude a significant portion of data and their contribution to total risk. Identifying the entire distribution of event sizes and their frequencies is better suited for understanding the relative contributions to total risk from high and low consequence events. If the distribution of event sizes does follow a law, the finite size of data-sets makes identifying the law difficult. This paper outlines the steps required to utilise empirical data to inform the risk of strategic threats and support decision-makers to prioritise treatment options according to their relative contributions to total risk. Potential pitfalls and limitations are also described.     

Liquidity risk and stock performance during the financial crisis

We investigate whether and how ex-ante liquidity risk affects realized stock returns during the global financial crisis of 2008–2009 in international equity markets. We find that stocks with higher pre-crisis return exposure to global market liquidity shocks experience larger price reductions during the crisis period. Our findings provide further insight into the comprehensive picture of the effect of liquidity risk on asset prices, especially in an international context and under different market conditions.     

The art of risk management: the crucial role of the global art insurance industry in enabling risk and security

This article investigates the under-researched sphere of insurance. It uses empirical research data to focus on one case study, the London art world, to analyse how the global art insurance industry ‘does’ security and how it enables risk and security to be embraced. Examining how the industry plays a crucial role in the security of art and within the art world itself, the article argues that the global art insurance industry’s role is largely beneficial for the art world because by enabling risk to be embraced through insurance, its pre-crime and post-crime responses, and its influence ‘beyond’ insurance, it emboldens and fuels the dynamic, thriving global art world.     

Market-specific and currency-specific risk during the global financial crisis: Evidence from the interbank markets in Tokyo and London

This paper investigates how international money markets reflected credit and liquidity risk during the global financial crisis. After matching the currency denomination, we examine how the Tokyo Interbank Offered Rate (TIBOR) was synchronized with the London Interbank Offered Rate (LIBOR). We find remarkably asymmetric responses in market-specific and currency-specific risk during the crisis. The regression results suggest that market-specific credit risk increased the difference across markets, whereas liquidity risk caused the difference across currency denominations. They also support the view that liquidity shortage of the US dollar occurred in international money markets during the crisis. Coordinated central bank liquidity provisions were useful in reducing the liquidity shortage of the US dollar, but their effectiveness was asymmetric across markets.     

Individual financial risk tolerance and the global financial crisis

We investigate individual investors’ tolerance towards financial risk by focusing on changes associated with the global financial crisis (GFC) of 2007–2009. Financial risk tolerance (FRT) is analysed longitudinally controlling for demographic, socio‐economic and regional variations. In absolute terms, the change in FRT is small and contrasts with a popular view that risk tolerance is an elastic psychological state overly influenced by the pervading market conditions. Even in the presence of significant financial events, FRT tends to be a reasonably stable attribute in the shorter term but possibly influenced and reshaped by events more gradually over time.

Global systemic risk measures and their forecasting power for systemic events

Since the financial crisis of 2007–2009, many market-based systemic risk measures have been proposed. Prominent examples are MES, SRISK or ΔCoVaR. Based on a simulation study in an extended banking network model that incorporates several sources of systemic risk, we analyze how well these systemic risk measures perform in indicating the risk of a systemic event. For this analysis, the systemic risk measures of the banks that default and whose default is followed by a systemic event are compared with the systemic risk measures of those defaulting banks for which no subsequent systemic event can be observed. Within the simulation study, we find that many bank-individual systemic risk measures are statistically significant in explaining the likelihood of a systemic event after a bank’s default. However, the economic significance of the bank-individual systemic risk measures is relatively low.     

Domestic fire risk: a narrative review of social science literature and implications for further research

In this paper, we make the case for more social science research into fire incidents and fire-related risk behaviour. Unlike other vulnerabilities, such as crime, illness or risk-associated activities such as smoking, or accident avoidance, remarkably little research has focused on this area. This is perhaps surprising given the propensity for fire, its emotional, social and economic impacts, and evidence that fires and fire victims are not equally distributed across socio-demographic or geographical domains. In making our case, we outline: recent numbers and trends in incidents in the UK, focusing on domestic incidents and recent policy developments affecting fire and rescue services. Next, we review the social-science based literature on fire incidents, suggesting that while this offers useful insight, much more needs to be done to develop a rigorous evidence base. While we would not want to dismiss or downplay existing social science contributions, our contention is that a considerable number of opportunities exist for further work in this area. Consequently, we propose a number of ways in which popular ideas about risk theory can be applied to a domestic fire context and raise a number of questions that social scientists are well positioned to contribute to an interdisciplinary understanding of domestic fire incidents and associated risks.

Public sector reform implications for performance measurement and risk management practice: insights from Australia

In 2013, the Australian Public Service was subject to a process of governance, accountability and performance reform. The implications of these reforms for micro-level practices are unknown. The authors’ empirical findings show that the reforms developed in three stages, each of which has significant implications for embedding performance measurement and risk management within a broader management control system.     

Perceptions of pre-service teachers on seismic risk and their implications for science education: a comparative study between Spain and Portugal

Abstract

This study investigated the importance given by two groups of pre-service teachers of primary education from Spain and Portugal to seismic risk in a framework of different natural risks, both in personal terms and as future teachers. A questionnaire was used for data collection. Some questions about the seismic phenomenon were also included. The sample groups consisted of 110 students from an institution in Spain and 121 from one in Portugal. Both institutions are in cities affected by the historic Lisbon earthquake of 1755. The results showed that the risk of forest fire was the first choice for classroom study in both cases. The Spanish group was also more focused on the importance of other risks like flood and drought. The Portuguese group showed a greater concern with seismic risk, frequently referring to their own historic earthquake of 1755. A few gaps in knowledge concerning earthquake prediction and comparing seismic risk in different regions of their own countries were also found. In accordance with the results, it is suggested that training courses for primary school teachers should include Disaster Risk Education in Science Education for a better understanding of the impact of various hazards and a greater concern with seismic risk due to its particular features, especially in regions where the seismic pattern is characterized by long seismic cycles with major earthquake episodes.     

Enterprise risk management in financial groups: analysis of risk concentration and default risk

In financial groups, enterprise risk management is becoming increasingly important in controlling and managing the different independent legal entities in the group. The aim of this paper is to assess and relate risk concentration and joint default probabilities of the group’s legal entities in order to achieve a more comprehensive picture of a financial group’s risk situation. We further examine the impact of the type of dependence structure on results by comparing linear and nonlinear dependencies using different copula concepts under certain distributional assumptions. Our results show that even if financial groups with different dependence structures do have the same risk concentration factor, joint default probabilities of different sets of subsidiaries can vary tremendously.

融资约束与制造业的全球价值链跃升

本文从融资约束的视角,探讨了如何实现我国制造业在全球价值链中跃升的问题。通过采用2001-2011年中国与其他41个经济体的双边贸易数据及非竞争性投入产出表,测算中国各产业在全球价值链中的嵌入度和地位,并实证研究了融资约束对我国产业在全球价值链的嵌入度和地位的影响效应。研究发现,融资约束是决定我国产业在全球价值链中嵌入度的关键因素。当融资约束较少时,可以带动产业在全球价值链中地位的升级;如果融资约束较大,则会引致产业向价值链低端偏移。此外,出口目标市场的金融发展水平越高,会一定程度上阻碍我国产业在全球价值链中的跃升,实施出口“地区多元化”的贸易战略将更有利于我国制造业产业的转型升级。     

Reduction of estimation risk in optimal portfolio choice using redundant constraints

It is well known that when the moments of the distribution governing returns are estimated from sample data, the out-of-sample performance of the optimal solution of a mean–variance (MV) portfolio problem deteriorates as a consequence of the so-called “estimation risk”. In this document we provide a theoretical analysis of the effects caused by redundant constraints on the out-of-sample performance of optimal MV portfolios. In particular, we show that the out-of-sample performance of the plug-in estimator of the optimal MV portfolio can be improved by adding any set of redundant linear constraints. We also illustrate our findings when risky assets are equally correlated and identically distributed. In this specific case, we report an emerging trade-off between diversification and estimation risk and that the allocation of estimation risk across portfolios forming the optimal solution changes dramatically in terms of number of assets and correlations.
