LVH: consequences associated with cardiac remodeling

With increased hemodynamic stress, the heart must adjust to meet the greater demands placed upon it. This adjustment frequently involves an alteration or remodeling in its structure or geometry, which augments its performance and helps to maintain adequate function under changing conditions. One of the most important forms of remodeling that the heart may undergo is an increase in muscle mass in response to a pressure or volume overload or myocardial injury. This increase in muscle mass is known as left ventricular hypertrophy (LVH). LVH is of great importance from a risk selection perspective for two reasons: it is common, and it is associated with a significant increase in both morbidity and mortality risk. Thus, it is critical that both underwriters and medical directors be aware of this form of remodeling, its causes, diagnosis and consequences.     

Comparing bank concentration across countries

Cross-country comparisons of traditional measures of concentration, such as the Herfindahl index, are of limited use for answering normative questions such as: ‘Is the banking system too concentrated in our country?’ This paper develops a measure of concentration, essentially by normalising the Herfindahl index by a minimum feasible value for that index based on market size for each country. A formal derivation is given, and the measure is related to the mark-up of price over marginal cost for banking services. The empirical implications of the new measure are illustrated by reference to some recent studies.     

Compensation vs. benefits: who gets paid more? A new survey analysis reveals the answer and possible causes

There is a discrepancy in pay between benefits and compensation professionals. These authors report on the results of a survey that measured the discrepancy and suggest possible reasons for the difference. They observe that, if benefits professionals are to reach pay equity with their compensation counterparts, they may need to play a strong role in helping organizations recognize the importance of benefits as a component of total reward strategy.
