Deoxynivalenol (DON) in wheat: an example of weighing the pros and cons of food stuffs

A Committee of the Health Council of the Netherlands advised on deoxynivalenol (DON), a mycotoxin occurring in cereals. TDIs of 1.0 and 0.5?µg.kg_{body weight} ^?1.day^?1 have been based on mice and pig studies in which DON reduced growth. In 1999, the 50^th and 95^th percentiles of DON intake by 1‐4‐year‐old children were, respectively, 1.3 and 2.4?µg.kg_{body weight} ^?1.day^?1. The Committee considered: (i) TDI contains safety factors, (ii) a slightly reduced weight gain is not necessarily harmful, (iii) when growth rate is highest, children consume little or no wheat, and (iv) in real life, exposure varies, causing the effect to be smaller. The Committee concluded that an exposure that only incidentally exceeds—up to about five times—0.5?µg.kg_{body weight} ^?1.day^?1 very unlikely inhibits weight gain. More severe effects on immunity, fertility and the foetus may occur at intakes higher than 2.5µg.kg_{body weight} ^?1.day^?1. Nonetheless, toxin exposure should be kept as low as possible. The Committee advised to agriculturally reduce DON content; second one may exclude wheat with high DON content for human consumption. Limits of 500 and 100?µg/kg_wheat prevent exposure exceeding 1.5 and 0.5?µg.kg_{body weight} ^?1.day^?1, respectively. As wheat products are good sources of nutrients, the Committee advised against discouraging their consumption.

Learning by Trial and Error: A Case for Moot Courts

This article describes the development of a computer tutorial for use in a history of economic ideas class. An early version of the tutorial contained ten topics, ranging from early Mercantilist thought to Jevons's marginal utility analysis. These concepts were presented in three ways: verbally, graphically, and in summary form. Student critiques were used to extend the content and revise the mode of presentation.

This article examines the notion of distortion of copulas, a natural extension of distortion within the univariate framework. We study three approaches to this extension: (1) distortion of the margins alone while keeping the original copula structure; (2) distortion of the margins while simultaneously altering the copula structure; and (3) synchronized distortion of the copula and its margins. When applying distortion within the multivariate framework, it is important to preserve the properties of a copula function. For the first two approaches, this is a rather straightforward result; however, for the third approach, the proof has been exquisitely constructed in Morillas (2005). These three approaches unify the different types of multivariate distortion that have scarcely scattered in the literature. Our contribution in this paper is to further consider this unifying framework: we give numerous examples to illustrate and we examine their properties particularly with some aspects of ordering multivariate risks. The extension of multivariate distortion can be practically implemented in risk management where there is a need to perform aggregation and attribution of portfolios of correlated risks. Furthermore, ancillary to the results discussed in this article, we are able to generalize the formula developed by Genest &; Rivest (2001) for computing the distribution of the probability integral transformation of a random vector and extend it to the case within the distortion framework. For purposes of illustration, we applied the distortion concept to value excess of loss reinsurance for an insurance policy where the loss amount could vary by type of loss.     

Why persistent high inflation impedes growth? An empirical assessment of threshold level of inflation for India

In the policy debate on growth–inflation trade-off and the role of monetary policy in managing the trade-off in the short-run, theoretical and empirical research suggests the presence of a country specific threshold level of inflation. Empirical findings of this paper suggest that for India the threshold level of inflation could be around 6%. The inflation target for monetary policy may have to be somewhat lower than the growth maximizing threshold, since any positive inflation could be a risk to inclusive and sustainable growth objective.

The impact of jump risks on nominal interest rates and foreign exchange rates

This article investigates the relationship between the nominal interest rate and inflation and also the forward exchange rate under a general specification of the underlying processes govering the foreign exchange rate. There are three distinct risks that affect the relation between the real rate of interest and the nominal rate namely, consumption risk, diffusion risk, and the existence of jump risks of inflation. Jump risks lower the nominal interest rate because of jump hedging of a nominal bond. The forward exchange rate depends on the expected depreciation of the domestic currency as well as these three risks. As the domestic jump risks increase, the domestic nominal interest rate decreases and the forward exchange rate decreases.
