Samsung Card Lending Model (SCLM) analyzes cash flow in individual accounts and measures the level of company-wide risk. Serving as a risk and portfolio management model in the consumer lending business, the main features of SCLM are as follows. Default ratios such as intrinsic balance default...

The Gaussian sequence model can be obtained from the high-dimensional regression model through principal component analysis. It is shown that the Gaussian sequence model is equivalent to the original high-dimensional regression model in terms of prediction. Under a sparsity condition, we...

In this paper, we consider a semiparametric regression model where the unknown regression function is the sum of parametric and nonparametric parts. The parametric part is a finite-dimensional multiple regression function whereas the nonparametric part is represented by an infinite series of...

This study examines the intraday formation process of transaction prices and bid–ask spreads in the KOSPI 200 futures market. By extending the structural model of Madhavan, A., Richardson, M., and Roomans, M. (<link href="#bib14">1997</link>), we develop a unique cross‐market model that can decompose spread components...

This study examines if informed trading is present in the index option market by analyzing the KOSPI 200 options, the most actively traded derivative product in the world. The spread decomposition model developed by Madhavan, Richardson, and Roomans (1997) is utilized and the adverse‐selection...

This study investigates the market interdependence among the Dow Jones (USA), Nikkei225 (Japan), and KOSPI200 (Korea) index futures markets from May 2002 to July 2009, which is divided into three distinct periods: the normal growth, accelerated growth and declining growth (crisis) periods. We...

This article examines the information content of trade size and investor performance in a unified framework, using the price contribution (PC) measure proposed by Barclay and Warner (1993). Several interesting results obtained through the analysis of a unique dataset of KOSPI200 futures are...

This study examines the forecasting performance of the Taylor rule on the exchange rate when there is uncertainty in the structural breaks in a small open economy. Using the combination window method, which considers the uncertainty of the size of the estimation window, we find that the...
