This paper shows how risk mitigation through export credit insurance could increase exports to high risk importing countries. The key result is that the export response curve is more inelastic in the presence of payment risk, and the effect of insurance is to make the export curve more elastic....

Long memory, and more precisely fractionally integration, has been put forward as an explanation for the persistence of shocks in a number of economic time series data as well as to reconcile misleading findings of unit roots in data that should be stationary. Recent evidence suggests that long...

This study uses results from marginal effects estimates across the foods and points of the food chain to rank the foods and food chain points in order of intensity of likelihood of a terrorist attack. The results show that young people, low incomers ($35,000), those with medium to low knowledge...

This paper investigates whether the assumption of Brownian motion often used to describe commodity price movements is satisfied. Using historical data from 17 commodity futures contracts specific tests of fractional and ordinary Brownian motion are conducted. The analyses are conducted under the...

The purpose of this paper is to develop a general approach to valuing commodity-linked bonds (CLBs) based on the Heath-Jarrow-Morton (HJM) framework. The model deals with four dimensions of uncertainty: prices of the underlying commodity, the value of firm that issues bonds, interest rates, and...

This paper presents a model and framework for pricing degree-day weather derivatives when the weather variable is a non-traded asset. The paper compares the options prices from the recommended model and compares it to a typical insurance-type model.

To reduce vulnerability and food insecurity this paper investigates the economics of micro-credit. We provide a model that shows how a micro-credit market based on trust can co-exist with a commercial collateral-based market. This model is developed in detail and certain propositions are...

This paper presents preliminary results on the possible demand for weather insurance in China. Results from 1,564 farm households from Western and Central China between October 2007 and October 2008 suggest that the greater risk for farmers is drought followed by excessive rain. Heat is less...
