The paper aims to investigate empirically the effects of several types of financial restraints on financial development for the case of the Iran. Two hypotheses addressed and discussed in the context of the McKinnon/Shaw and the monopoly bank model. A conditional co-integration model has been employed to carry out the empirical investigations. The long and short-run analysis show that fin...

We analyze properties of links which have diagrams with a small number of negative crossings. We show that if a nontrivial link has a diagram with all crossings positive except possibly one, then the signature of the link is negative. If a link diagram has two negative crossings, we show that the signature of the link is nonpositive with the exception of the left-handed Hopf link (with possible...
