Cross-protection against non-HPV16/18 types and the emergence of broad spectrum vaccines protecting against multiple HPV types will influence the cost-effectiveness of future screening. To assess this influence we used an individual-based simulation model describing the relation between 14 HPV types and cervical disease, allowing the occurrence of multiple type infections. Screening scenarios f...

Analyzing Cost Efficient Production Behavior Under Economies of Scope: A Nonparametric Methodology In designing a production model for firms that generate multiple outputs, we take as a starting point that such multi-output production refers to economies of scope, which in turn originate from joint input use and input externalities. We provide a nonparametric characterization of cost efficient ...

Information asymmetry in stock market can increase the risk of investment which in turn increases the capital cost of firms.

We measured information asymmetry by lack of earnings transparency. Therefore we examine the effect of earnings transparency on cap...
