    Kunhong Kim
    Pages 3-28
  • Abstract ( Eng | Kor ) || PDF
    •    This paper considers a dynamic general equilibrium model of a small open two-period endowment economy with tradable and non-tradable goods. Under some mild assumptions regarding the form of the representative agent's inter-temporal utility function, it is shown analytically that a temporary positive output shock in the tradable good sector increases national saving and improves the current account balance whereas a similar positive output shock in the non-tradable good sector reduces national saving and deteriorates the current account balance if the inter-temporal elasticity of substitution between the current and future consumption is greater than the intra-temporal elasticity of substitution between the tradable and non-tradable good consumption.

    • Division of Labor and Contests
      Sung-Hoon Park


         We examine how changes in division of labor affect rent dissipation and expected payoffs for parties in contests. To do so, we model three contests: a contest with parties (CP), a two-stage contest with delegation (CD), and a two-stage contest with parties and delegation (CPD). Then we obtain a unique equilibrium in each contest, and compare the equilibrium of CD to those of CP and CPD. The results are as follows. First, compared to rent dissipation in CP and that in CPD, rent dissipation in CD is low. Second, compared to the sum of expected payoffs for parties in CP and that in CPD, the sum in CD is high. The results may be referred to as the division of labor in contests.

    Hospital Care for the Newborns between Weekdays and Weekend
    Beomsoo Kim, Minjee Kim
    Pages 51-64
  • Abstract ( Eng | Kor ) || PDF
    •    This study analyzed whether the higher mortality of weekend-born children compared to weekday-born are due to lowered staffing ratio over the weekend or unobserved health condition of newborns. Unlike the previous studies we use the census of US births and truly exogenous birth timing by focusing on vaginal deliveries without induction or stimulation. The statistically significantly higher mortality rate for weekend-born babies was no longer observed when birth weight was included as a proxy for unobserved health condition and these results are robust across various samples and different locations. Our findings are robust to high risk groups such as cesarean section and low birth weight samples.

    • The Effects of Foreign Investors on the Korean Equity Market during the 2007~2008 Financial Crisis
      Gab-Je Jo


         This paper investigates the effects of foreign equity investment on the Korean market during the 2007~2008 financial crisis. The empirical results indicate that foreign investors show positive feedback trading behavior and domestic institution investors show negative feedback trading behavior. In terms of volatility, I have found evidence that foreign investors' net selling behavior tends to increase market volatility, while net buying activity by domestic investors increases volatility in the market.

    • How Do We Utilize a New 'Final Demand-Final Output Model' in Economic Analysis?: Based on the Nature and Usefulness of the Model
      Ho Un Gim


         On the grounds of the latest research findings and results from the models of input-output (IO) and output-output (OO), which was first developed by the author as the alternative model of the IO model, the specific objectives of this paper can be summed up as follows.
         (1) We develop a new final demand-final output (FF) model as the another alternative model of the traditional IO model and verify the nature, economic implications and usefulness of the model.
         (2) We derive the varied types of multipliers, linkage and induced economic effects for the newly developed FF model.
         (3) We examine the effectiveness and usefulness of the alternatively developed FF model through counting the various sectoral multipliers and induced effects based on raw data of ¡º2010 Input-Output Tables¡» complied by the Bank of Korea.
         Moreover, the Spearman's rank correlation coefficients, , are empirically counted to observe the relevant structural economic characteristics of each endogenous sector between types of multipliers, and between linkages and induced effects.
