Exports and growth: an econometric analysis

This paper dicusses the sources of rapid economic growth in Koreaı in recent times and their economic implications by means of three types of econometric tests based on the modern theory of cointegration, the dominant role of demand over supply and the significant degree of economies of scale due to the spillover effects of human capital and of technological diffusion. The empirical growth profile of Korea in recent times seems to vindicate some of the major tenets of the new growth theory

Constrained games as complementary eigenvalue problems

AbstractA class of two-person nonzero sum games where the strategy choices are constrained in some form for each player is analyzed here to show the equivalent nonlinear programs which must be solved for the Cournot-Nash equilibrium. This equilibrium solution is shown in appropriate cases to lead to complementary eigenvalue problems, which have applications in normal solutions of stochastic LP models and optimal design problems in linear regression theory

Nonparametric efficiency analysis under uncertainty

Production and cost frontiers of a firm in an industry are directly affected by the uncertainty of market demand and the uncertainty of input availability. The nonparametric approach of data envelopment analysis is generalized here in both static and dynamic directions by incorporating these uncertainties

Modelling Exchange Rate Volatility

Two types of statistical models are empirically applied to test the pattern of volatility in the exchange rate markets. One considers the autoregressive models and tests the random walk hypothesis. The other considers the conditional variance process and tests the hypothesis of chaotic dynamics. Empirical results mostly support the random walk hypothesis and also the existence of Lorenz-type chaos

Recent Models in Dynamic Economics: Problems of Estimating Terminal Conditions

Recent policy applications of control theory methods in dynamic economic models raise the issue of imposing the transversality condition for determining a unique optimal control policy. In a stochastic framework this issue involves alternative methods of estimation, which are discussed here both theoretically and empirically. The economic implications of the alternative methods are analyzed here in some detail through several recent dynamic models in economic growth and exchange rate instability
