  • Abstract ( Eng | Kor ) || PDF
    •    Garratt et al. (2006) provides a practical modelling strategy that incoporation long-run structuala relationships. suggested by economic theory, in an otherwise unrestricted VAR model. we apply this strategy to construct a small quartely macroeconometric model of Korea and etstimate the benchmark model over 1982q2-2006q2 in nine variables; dometsic and foreign outputs. prices and interest rates, oil prices, the nominal effectetive exchange rate. and real money balances. In particular, we explicitly allow for the presence of structual breaks in the model, highlighting the signifiant impact of the 1997 Asian currency crisis on the macroeconomic performance of Korea during and after the crisis period. Overall estimation results are sensible in terms of identifying the long-run cointergrating relationships weakly consistent with the uderlying theory and further dynamic weakly counterfactual analysis in the context of bot structual impulse response functions and the probability forecasting of innovation and output growth.

    • Optimal Monetary Policy in a Small Open Economy Exporting Durable Consumption Goods
      Kyoung Soo Han


         This paper examines the implications of durable consumption goods for optimal monetary policy in a small open economy. The effects of technology and monetary policy shocks are larger in an economy producing durabe goods. A welfare-theoretic loss function is a quadratic function of the present and future output gaps and domestic inflation rates. but higher weight is given to the present output gap when consumption goods are more durable in nature. However, the optimal target criterion is a linear relation that the state-contingent evolution of domestic inflation and the output gap must satisfy. Just as in a closed economy with only nondurable goods. and this is unaffected by the degree either of openness or of the durability of the consumption goods.

  • Abstract ( Eng | Kor ) || PDF
    •    In contrast to the argument of the VoC framwork that the firm should be centered in the analysis of economic efficiecny over gloablization, this paper suggests that the state still improves the efficiency of economic activities through its initiative and coordinating capacity. We show that economic restructuring, in the areas such as work organization. R&D system. and corportate governance reform, is still initiated and coordinated by the government. and that organizational traditions, such as state owenership in France and family control in Korea, are sustained. The venture industry of France and Korea is the case

    Peer Characteristics and the Effecticeness of Single-Sex Schooling
    Insook Cho
    Pages 315-346
  • Abstract ( Eng | Kor ) || PDF
    •    Single-sex schools have been suggested as an alternative to failing traditional public schools on the grounds that they provided a more favorabel learning environment. However, estimated gains to academic achievment from single-sex schooling are generally confounded by selection bias since single-sec schools tend to attract different students than mainstream schools in most countries. This paper examines the difference in academic achievment between students in single-sex and coeducational shcools across countries. The results suggest that single-sex schooling does not always have a positive influence on student achievement and that the selection process often explains a significant proportion of the observed achievement gap betweeen single-sex and coeducational schools.

    • Corresponding to the Result of Elections, How the Korean Investors form a Expectation for Future State?
      KiHyung Kim, Yong-Joo Lee


         It is an objective approach, which is free from investors subjective risk-preferences, to estimate investors' market-expectation through the implied risk-neutral probability distribution function. Under the assumption of mixture log-normal distribution, which gives more affluent implications than the traditional simple log-normal distribution. this research investigates Korean investors' expectations around the 16th Korean presidential election and the 17th Korean general election. The 16th presidential election showed a typical result that the result of election reduced the market uncertainity. On the other hand, the result of the 17th general election increased the uncertainity. However, both cases implied that the Korean investors made a reasonable decision and the Korean financial market was operated efficiently.

    • A Study on Relations between the KOSPI200 Index Market and Trade Volumes by Types of Traders in the KOSPI200 Futures Market
      Shiyong Yoo, Taehoon Kwon


         In this paper, we researched how the trade volumes by types of traders in the KOSPI200 futures market might influence returns and volatilities of KOSPI200. Daily transaction and price data sets in both the KOSPI200 futures market by types ofr traders and the spot market from May 1997 to December 2005. were used. Types of traders are individuals, institutions, and foreigners. Trade volumes were factored into expected and unexpected ones. Unexpected net long futures positions of individual and institutional investors cause decreased spot returns, whereas those of foreign investors causes increased spot returns. Unexpected spot volumes have a positive effect on spot returns. Both expected and unexpected net long futures positions of foreign investors have no effect on spot volatilities. While unexpected net long futures positions of institutional investors have a negative effect on spot volatilities. It turned out that individual investors trade volume in KOSPI200 futures have most largest effects on spot volatilities than any other types of traders.
