Survey Of Resolution And Restructuring In Europe: Pre- And Post-Brrd, Christian M. Mcnamara, Carey K. Mott, Salil Gupta, Greg Feldberg, Andrew Metrick

Journal of Financial Crises

This paper surveys 19 case studies of bank resolutions and restructurings across 15 Key Design Decisions. It focuses on interventions that occurred in Europe both in the years leading up to the adoption of the Bank Recovery and Resolution Directive (BRRD) in 2014 (when many jurisdictions were constrained by a lack of legal authority) and in the years after the BRRD was in place. The main themes that emerge are: (a) the need for resolution and restructuring to eliminate uncertainty about an institution’s solvency by closing it, recapitalizing it, or merging it with a healthier institution; (b) the importance of …

Municipal Waste Management Based On Geomechanical Assessments Of The Landfill Site Slope – A Case Study In Southern Poland, Tomasz Janoszek, Phu Minh Vuong Nguyen, Jacek Grabowski

Journal of Sustainable Mining

Over time, municipal waste landfills tend to go higher and become larger. The stability of the municipal landfill slope is one of the basic geotechnical tasks. This task ensures continuous waste deposition on the landfill surface and safety in its surroundings. With the increasing height and volume of the landfill, it is difficult to estimate the available area of the municipal landfill, where more waste can be safely deposited due to a number of variable factors, such as the geotechnical conditions of the municipal landfill, the morphological composition, age, and degree of compaction and decomposition of the deposited waste.

Mpt And Capm Mismeasure Risk, Gary N. Smith

Pomona Economics

Mean-variance analysis and the capital asset pricing model provide many useful insights for investors who want to measure and manage risk. However, their focus on short-term returns is of limited use and potentially misleading for investors with long horizons. A value investing approach suggests that risk might be better measured by long-run uncertainty about asset income than by short-run uncertainty about asset prices.
