    The paper shows that between the late 1980s and 1997, the year when Korea was engulfed in a financial crisis, its corporate-sector profitability was on a decreasing trend, albeit short-term ups and downs. The evidence presented in the paper suggests that Koreaā€™s corporate and financial sectors had been highly vulnerable to a crisis for some years before 1997 and the actual timing of the crisis was triggered by the financial crisis in Thailand in July 1997 and its contagion effect.Asian crisis; Korean economy; corporate sector insolvency.

    Technical Efficiency in the Iron and Steel Industry: A Stochastic Frontier Approach

    In this paper we examine the technical efficiency of firms in the iron and steel industry and try to identify the factors contributing to the industry's efficiency growth, using a time-varying stochastic frontier model. Based on our findings, which pertain to 52 iron and steel firms over the period of 1978-1997, POSCO and Nippon Steel were the most efficient firms, with their production, on average, exceeding 95 percent of their potential output. Our findings also shed light on possible sources of efficiency growth in the industry. If a firm is government-owned, its privatization is likely to improve its technical efficiency to a great extent. A firm's technical efficiency also tends to be positively related to its production level as measured by a share of the total world production of crude steel. Another important source of efficiency growth identified by our empirical findings is adoption of new technologies and equipment. Our findings clearly indicate that continued efforts to update technologies and equipment are critical in pursuit of efficiency in the iron and steel industry.

    Current-induced domain wall motion in a nanowire with perpendicular magnetic anisotropy

    We study theoretically the current-induced magnetic domain wall motion in a metallic nanowire with perpendicular magnetic anisotropy. The anisotropy can reduce the critical current density of the domain wall motion. We explain the reduction mechanism and identify the maximal reduction conditions. This result facilitates both fundamental studies and device applications of the current- induced domain wall motion
