The Place of Risk Management in Financial Institutions

The purpose of this paper is to address two issues. It defines the appropriate role played by institutions in the financial sector and focuses on the role of risk management in firms that use their own balance sheets to provide financial products. A key objective is to explain when risks are better transferred to the purchaser of the assets issued or created by the financial institution and when the risks of these financial products are best absorbed by the firm itself. However, once these risks are absorbed, they must be efficiently managed. So, a second part of the current analysis develops a framework for efficient and effective risk management for those risks which the firm chooses to manage within its balance sheet. The goal of this activity is to achieve the highest value added from the risk management undertaken.

A note on bounds for the cop number using tree decompositions

In this short note, we supply a new upper bound on the cop number in terms of tree decompositions. Our results in some cases extend a previously derived bound on the cop number using treewidth

An Iterative Auction for Spatially Contiguous Land Management: An Experimental Analysis

Tackling the problem of ecosystem services degradation is an important policy challenge. Different types of economic instruments have been employed by conservation agencies to meet this challenge. Notable among them are Payment for Ecosystem Services (PES) schemes that pay private landowners to change land uses to pro-environmental ones on their properties. This paper focuses on a PES scheme – an auction for the cost-efficient disbursal of government funds for selection of spatially contiguous land management projects. The auction is structured as an iterative descending price auction where every bid is evaluated on the basis of a scoring metric – a benefit cost ratio. The ecological effectiveness and economic efficiency of the auction is tested with data generated from lab experiments. These experiments use the information available to the subjects about the spatial goal as the treatment variable. Analysis indicates that the information reduces the cost-efficiency of the auction. Experience with bidding also has a negative impact on auction efficiency. The study also provides an analysis of the behavior of winners and losers at the final auction outcome. Winners and losers are found to have significantly different behavior with winners bidding much higher than their costs than losers.Ecosystem Services, economic experiments, auctions, spatial contiguity, Environmental Economics and Policy, Institutional and Behavioral Economics, Land Economics/Use, Resource /Energy Economics and Policy, Q,

Ceramic composition at Chalcolithic Shiqmim, northern Negev desert, Israel: investigating technology and provenance using thin section petrography, instrumental geochemistry and calcareous nannofossils

Technological innovations in ceramic production and other crafts are hallmarks of the Chalcolithic period (4500–3600 BCE) in the southern Levant, but details of manufacturing traditions have not been fully investigated using the range of analytical methods currently available. This paper presents results of a compositional study of 51 sherds of ceramic churns and other pottery types from the Chalcolithic site of Shiqmim in the northern Negev desert. By applying complementary thin section petrography, instrumental geochemistry and calcareous nannofossil analyses, connections between the raw materials, clay paste recipes and vessel forms of the selected ceramic samples are explored and documented. The study indicates that steps in ceramic manufacturing can be related to both technological choices and local geology. Detailed reporting of the resulting data facilitates future comparative ceramic compositional research that is needed as a basis for testable regional syntheses and to better resolve networks of trade/exchange and social group movement
