    The asymmetric behavior and procyclical impact of asset correlations

    No full text
    This paper examines the behavior of asset correlations with the market returns in the asymptotic single risk factor (ASRF) approach of the Basel II accord on regulatory capital requirement. Over a sample period from 1988 to 2007, we find that asset correlations are positively related to firm size, but negatively related to firm default probability. Asset correlations are also industry specific, as firms in media, transportation, pharmaceutical, and semiconductor industries exhibit higher asset correlations than those in retail and consumer staples. Most importantly, asset correlations are asymmetric and have a procyclical impact on the real economy after controlling for these effects. They tend to rise during economic downturns, but decline during economic upturns. The average magnitude of the rise is larger than that of the decline. These findings suggest that asset correlations may be underestimated during economic downturns, and may provide policy implications for the capital requirement framework. © 2011 Elsevier B.V.Shih-Cheng Lee, Chien-Ting Lin and Chih-Kai Yan

    Low-complexity parallel Chien search structure using two-dimensional optimization

    No full text
    To achieve a high-throughput decoder, massive-parallel computations are normally applied to the Chien search, but the parallel realization increases the hardware complexity significantly. To reduce the hardware complexity of the parallel Chien search, this brief proposes a 2-D optimization method. In contrast to the previous 1-D optimizations, the proposed method maximizes the sharing of common subexpressions in both the row and column directions. All the partial products needed in the parallel structure are represented in a single matrix, and the finite-field adders are completely eliminated in effect. Simulation results show that the proposed 2-D optimization leads to a significant reduction of the hardware complexity. For the (8191, 7684, 39) BCH code, the count of XOR gates in the parallel Chien search is reduced by 92% and 22%, compared to the straightforward and strength-reduced structures, respectively.111921sciescopu
