the debt is one of the principal component of accounting equation and capital structure of most companies. during last fifteen years the usage trend of debt was increasingly improved in companies' eps. american ones. in this research we tried to answer the following question: is there any meaningful relation between debt ratio and return on assets (roa) in sec of tehran and its industries?...

On-orbit servicing is the process of improving a space-based capability through a combination of in-orbit activities which may include inspection; rendezvous and docking; and value-added modifications to a satellite’s position, orientation, and operational status. As a means to extend the useful life or operational flexibility of spacecraft, on-orbit servicing constitutes one pathway to a respo...

This paper empirically analyzes the effect of competition on rating quality under the "issuerpay" compensation scheme. Using hand-collected data of collateralized debt obligations (CDOs), we specify the competition among credit rating agencies with a discrete game framework and test its influence on the rating quality. We find that competition raised the probability of choosing lenient rating b...

We study optimal macroprudential policy in a model in which unconventional shocks, in the form of news about future fundamentals and regime changes in world interest rates, interact with collateral constraints in driving the dynamics of financial crises. These shocks strengthen incentives to borrow in good times (i.e. when “good news” about future fundamentals coincide with a low-world-interest...

The use of humans to service satellites designed for servicing has been adequately demonstrated on the Hubble Space Telescope and International Space Station. Currently, robotic on-orbit servicing technology is maturing with risk reduction programs such asOrbital Express. Robotic servicing appears to be technically feasible and provides a set of capabilities which range from satellite inspectio...

The cost of servicing a warranty depends, amongst other factors, on the type of repair performed under warranty. Although ‘‘all minimal repair’’ and ‘‘all replacement’’ policies are easy to implement and analyze, they are not always feasible and/or practical. Having a combination of different types of repair often leads to lower warranty servicing costs. In this article, to reduce the warranty ...

Loan spreads are analysed for two types of loans. The …rst takes losses at maturity only; the second one follows the formulation of CFOs (Collateralized Fund Obligations), with losses registered over the lifetime of the contract. In both cases, the implementation requires the choice of a process for the underlying asset value and the identi…cation of the parameters. The parameters of the proces...
