Agricultural value chain financing (VCF) is an emerging phenomenon in the region but it is not well studied. Historically, small- and medium-sized famers experience problems accessing formal finance. Participation in a well-structured and dynamic supply chain seems to improve chances of...

This Working Paper serves as a technical background note for the Farm-level analysis of risk, risk management strategies and policies (OECD Food, Agriculture and Fisheries Working Papers No.26). It describes: 1) the data source and analytical methods employed to measure risk exposure at the farm...

Groundwater resources are traditionally overexploited in arid and drought-prone regions with profitable irrigated agriculture, and the depletion of this groundwater results from a combination of the physical scarcity of surface sources and the lack of effective control of use rights on the part...

Extreme events occur rarely, but these are often the circumstances where an insurance coverage is demanded. Given the first, say, n moments of the risk(s) of the events, one is able to compute or approximate the tight bounds for risk measures in the form of E(ψ(x)) through semidefinite...

We propose a simple analytical framework to measure the value added or subtracted by stop-loss rules—predetermined policies that reduce a portfolio’s exposure after reaching a certain threshold of cumulative losses—on the expected return and volatility of an arbitrary portfolio strategy....

Recent communications from the European Commission (EC) seem to suggest that a new stage in relation with natural disaster prevention and management has begun. New perspectives stemming from the different policies that impinge upon this issue have been gradually incorporated. Complex structural...

As the supply chain expands overseas, there is a growing need for managing supply chain disruptions from a cross-national perspective. This paper investigates whether or not supply chain disruption management (SCDM) can be universally applied. The universality of the SCDM framework is analyzed...

We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness. We also show that variance decompositions define weighted, directed networks, so that our connectedness measures are intimately...

This paper clarifies the relation between decisions of a risk-averse decision maker, based on expected utility theory on the one hand, and spectral risk measures on the other.

Typical questionnaires administered by financial advisors to assess financial risk tolerance mostly contain stereotypes of people, have seemingly unscientific scoring approaches and often treat risk as a one-dimensional concept. In this work, a mathematical tool was developed to assess relative...
