Social welfare is a major issue in both developing and developed countries, including Korea. Political parties are especially struggling with the choice between universal or selective welfare but hardly any clear guidelines exist. This paper reviews universal versus selective welfare concepts...

In binary discrete regression models like logit or probit the omis-sion of a relevant regressor (even if it is orthogonal) depresses the re-maining b coefficients towards zero. For the probit model, Wooldridge(2002) has shown that this bias does not carry over to the effect ofthe regressor on...

The paper discusses methodological topics of bankruptcy prediction modelling—unbalanced sampling, sample bias, and unbiased predictions of bankruptcy. Bankruptcy models are typically estimated with the use of non-random samples, which creates sample choice biases. We consider two types of...

In this article, we investigate the effectiveness of the credit facilities and foreign trade to combat the cycle duration in the industrial production index. The turning point methodology of Harding and Pagan was adapted to formulate the economic cycle. Using the industrial production index of...

The multinomial logit model with random coefficients is widely used in applied research. This paper is concerned with estimating a random coefficients logit model in which the distribution of each coefficient is characterized by finitely many parameters. Some of these parameters may be zero. The...
