I investigate the mechanisms through which idiosyncratic investment risk generates a fat tail of the wealth distribution. I set up a continuous time OLG model with a bequest motive and portfolio selection to show that idiosyncratic investment risk generates a Pareto tail in the wealth distribution. I calibrate my model to the U.S. economy and show that the wealth distribution in the simulated e...

Thylamys pallidior (O. Thomas, 1902) is a didelphid marsupial commonly called the white-bellied fat-tailed mouse opossum. A small mouse opossum, with tricolored pelage and a white venter, it has a seasonally incrassated tail, where fat deposits, primarily at the tail base, function in food storage. It is the most widely distributed species in the genus occurring from southwestern Peru and north...

Recent events in the financial and insurance markets, as well as the looming challenges of a globally changing climate point to the need to re-think the ways in which we measure and manage catastrophic and dependent risks. Management can only be as good as our measurement tools. To that end, this paper outlines detection, measurement, and analysis strategies for fat-tailed risks, tail dependent...

Carcass data were collected from market barrows and gilts (n = 325) slaughtered at a commercial slaughter facility in Canada to estimate carcass composition from longitudinal average fat depth and muscle depth measured automatically by a computerized real-time ultrasonic system. Similar and other ultrasonic measurements were also made manually from the same carcasses for comparison purposes. Re...

The performance of the wrap-around Viterbi decoding algorithm with finite truncation depth and fixed decoding trellis length is investigated for tail-biting convolutional codes in the mobile WiMAX standard. Upper bounds on the error probabilities induced by finite truncation depth and the uncertainty of the initial state are derived for the AWGN channel. The truncation depth and the decoding tr...
