Despite much research, debate continues about the impact of risk taking on a firm's future performance. Unlike prior studies, we propose that risk-return relationships evolve as firms age and learn, particularly in high-velocity settings where accumulated knowledge affects how firms respond to technological change. Discerning this requires three things absent from prior analyses: (1) studying a...

The return performance and factor sensitivities of Canadian equity real estate investment trusts (E-REITs) are examined. Today, typical and average Canadian E-REIT IPOs are correctly priced based on first-day and subsequent short-run returns. The overpricing evident earlier in the 1993-96 period for typical and average E-REIT IPOs has corrected. E-REITs are equity investments with about one-hal...

A test was designed that apparently examined a student’s knowledge of assignment and sequence before a first course in programming but in fact was designed to capture their reasoning strategies. An experiment found two distinct populations of students: one could build and consistently apply a mental model of program execution; the other appeared either unable to build a model or to apply one co...

Flood risk analysis is more complex in urban areas than that in rural areas because of their closely packed buildings, different kinds of land uses, and large number of flood control works and drainage systems. The purpose of this paper is to propose a practical framework for flood risk analysis and benefit assessment of flood control measures in urban areas. Based on the concept of disaster ri...

statistical analysis is used in hydrology where variables and processes are observed and stated in terms of numbers. the majority of hydrologic phenomena in nature, such as precipitation, runoff, evaporation, sediment transport, water quality properties, elc., are stochastic processes. however, in considering events on an annual basis, the occurence of the events may be assumed independant and ...

We study risk and return on farm and non-farm business enterprises in village economies. A risk-sharing benchmark predicts that only aggregate covariate risk contributes to the risk premium. An autarky benchmark predicts that overall fluctuation, idiosyncratic plus aggregate, is the only concern. Empirical findings from semi-urban and rural Thai households with extensive family networks quantif...

As increasing disbursements (such as costs and fees) risk portfolio leverage risk) may affect managed fund performance, analysts go beyond risk-adjusted return measures for performance appraisal. A methodology that assesses in a multidimensional framework is data envelopment analysis (DEA). variant of DEA inverse DEA. In this paper, applied to determine output (investment income benefit payment...

Background Obesity history may provide a better understanding of the contribution of obesity to T2DM risk. Methods 17,634 participants from the 1958 National Child Development Study were followed from birth to 50 years. Cumulative obesity dose, a measure of obesity history, was calculated by subtracting the upper cut-off of the normal BMI from the actual BMI at each follow-up and summing the ...
