The group of marginal zone B-cell lymphomas (MZL) comprises three different entities, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (currently called MALT lymphoma), nodal marginal zone B-cell lymphoma (previously known as monocytoid lymphoma), and splenic marginal zone B-cell lymphoma (with or without circulating villous lymphocytes).[1-3] Primary splenic and no...

The interplay of fibroblast growth factor (FGF) and nodal signaling in the Xenopus gastrula marginal zone specifies distinct populations of presumptive mesodermal cells. Cells in the vegetal marginal zone, making up the presumptive leading edge mesoderm, are exposed to nodal signaling, as evidenced by SMAD2 activation, but do not appear to be exposed to FGF signaling, as evidenced by the lack o...

The objective of the paper is to compare the effects of two alternative transport pricing rules: average cost and marginal social cost pricing. For both pricing scenarios, two alternative ways of using surpluses or financing deficits of the transport sector are used. The first is to change the marginal labour tax rate, the second way is to vary the level of social transfers. The effects of the ...

We provide an existence proof for Generalized Marginal Cost Pricing with given tax-subsidy rules. The novelty is that our approach allows for economic environments where all the generalized marginal cost pricing equilibria are inefficient in the aggregate. An example is recalled in order to suggest how non-pathological these environments are. Journal of Economic Literature Classification Number...
