The paper deals with three approaches to comparing the regression lines corresponding to two dependent groups when using a robust estimator. The focus is on the Theil–Sen estimator with some comments about alternative estimators that might be used. The first approach is to test the global hypothesis that the two groups have equal intercepts and slopes in a manner that allows a heteroscedastic e...

In traditional economics the decision-making process for individuals currently has effectively no role for ethics, as individuals are self-interested. The key concepts in economics which determine the role of ethics in the decision-making process are utility, rationality and methodological individualism and hence how these can be and are formulated and combined determines different roles for et...

The existing theoretical analysis of micro…nance focuses on the nature of the loan contract such as group liability. We draw attention to the role of missing or imperfect labor market in understanding some of the important ‘second generation’debates in micro…nance. Our analysis helps explain a number puzzles in micro…nance such as (i) high repayment rates with high interest rates, (ii) di¢ cult...

The large shareholders of Chinese public firms often pledge their shares for loans. Before the split share reform in 2006, loan terms were based on the book value of the firm. Since then, the share price has become critical for share pledged loans. ...
