    What lies beneath? The role of informal and hidden networks in the management of crises

    Crisis management research traditionally focuses on the role of formal communication networks in the escalation and management of organisational crises. Here, we consider instead informal and unobservable networks. The paper explores how hidden informal exchanges can impact upon organisational decision-making and performance, particularly around inter-agency working, as knowledge distributed across organisations and shared between organisations is often shared through informal means and not captured effectively through the formal decision-making processes. Early warnings and weak signals about potential risks and crises are therefore often missed. We consider the implications of these dynamics in terms of crisis avoidance and crisis management

    SoS in Disasters: Why following the manual can be a mistake

    According to both the US Geological Survey and the World Bank, 280billiondollarscouldhavebeensavedif280 billion dollars could have been saved if 40 billion dollars had been invested in disaster prevention. Natural and human-made disasters that have occurred over the last few years show that there is a gap in disaster prevention caused by the interconnected nature of risks, which cannot be foreseen with current risk management methods. In this paper we point out how disaster management could benefit from a SoS approach in emergency response and preparedness strategies. Using recent disasters as case studies, we identify some keys to success in managing a SoS in preparation, during and in the aftermath of a disaster. In particular, we discuss the idea of the interconnectedness of risks in independent and interdependent systems and the application of Boardman and Sauser’s concept of “creative disobedience”, which are fundamental for goal achievement of systems belonging to a SoS

    Decision aid problems criteria for infrastructure networks vulnerability analysis (regular paper)

    Natural disasters through infrastructure networks might aggravate or mitigate consequences to stakes. The objective of this paper is to characterize this kind of situation in order to provide a solid foundation for the decision aid. This characterization includes a description of the typology, actions and potential actions identification, determining preference systems, as well as a set of specific problems to each phase

    Consumption smoothing and vunerability in Russia

    Get PDF
    Applying bootstrapped quantile regression to the Russian Longitudinal Monitoring Survey (RLMS) data, we examine the channels through which individuals experience and seek to cope with changes in consumption. We find that married individuals living in small households, with educated heads in urban areas are better equipped to smooth consumption. Investigating the impact of idiosyncratic shocks, we find that the labour market is an important transmission mechanism allowing households to smooth their consumption but also exposing them to risk, mainly through job loss. Outside of pension payments the formal social safety net does not facilitate consumption smoothing, thus heightening the importance of informal coping institutions. It transpires that both support from relatives/friends and home production act as important insurance mechanisms for the most vulnerable

    Coping with economic shocks: Consumption Smoothing and the 1998 Russian Financial Crisis

    Get PDF
    Applying quantile regression techniques to Russian data we investigate the channels through which individuals experience changes in their well being. We find that married individuals in non-rural households with university-educated heads are less vulnerable to severe welfare shocks. For the most vulnerable individuals the labour market plays a key role in transmitting the effects of aggregate shocks through the unemployment channel whereas those individuals able to maintain their employment status are more able to cope with economic shocks. While increases in pension payments help individuals to cope with shocks, it transpires that vulnerable individuals rely more broadly on the support of relatives and the produce of their garden plots and dachas

    Risks in production and the management of labour

    The paper considers a (static) portfolio system that satisfies adding-up contraints and the gross substitution theorem. The paper shows the relationship of the two conditions to the weak dominant diagonal property of the matrix of interest rate elasticities. This enables to investigate the impact of simultaneous changes in interest rates on the asset demands.
