We show that there can be significant difference between risk preferences of individual investors and aggregate preferences toward risk in the economy. To demonstrate this, we investigate aggregate properties of an economy where all investors have convex utility functions corresponding to risk seeking behavior. In the case of risk seeking individual agents with identical initial endowments, ass...

2 This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator organism risk indexing tool (FIORIT). This tool aims to prioritise those fields most vulnerable in terms of their risk of contributing FIOs ...

Decision-making under risk assessment involves dealing with the matter of uncertainty, especially in projects such as tunnel construction. Risk control should include not only measures to reduce the possible consequence of incident, but also exploration measures (information collecting measures) to reduce the uncertainty of the incident. The classical risk assessment model in engineering is R =...

We show that in large symmetric auctions with conditionally i.i.d. common values and CARA preferences, the second-price auction raises more revenue than the …rst-price auction. We also show by an example that the ranking does not extend to general symmetric risk-averse preferences.

This paper presents a theoretical and empirical analysis of the impact of financial assistance to farms on crop biodiversity in an uncertain setting. The findings reveal that risk aversion is an important driving force for crop biodiversity conservation. Riskaverse farmers can hedge against the uncertainty they face by allocating land to different crop species. However, policies intended to sta...

We show that the production of information in financial markets is limited by the extent of risk sharing. The wider a stock’s investor base, the smaller the risk borne by each shareholder and the less valuable information. A firm which expands its investor base without raising capital affects its information environment through three channels: (i) it induces incumbent shareholders to reduce the...
