The scale invariant properties of wave functions in finite samples of one dimensional random systems with correlated disorder are analyzed. The random dimer model and its generalizations are considered and the wave functions are compared. Generalized entropic localization lengths are introduced in order to characterize the states and compared with their behavior for exponential localization. An...

This paper examines how equity analysts affect corporate liquidity policy and the value of cash. Greater analyst coverage reduces information asymmetry between a firm and outside shareholders and enhances the monitoring process, in turn increasing the value of cash and allowing firms to hold more cash. The cash-to-assets ratio increases by 5.2 percentage points when moving from the bottom analy...

Entities define their own set of rules under which they are willing to collaborate, e.g., interact, share and exchange resources or information with others. Typically, these individual policies differ for different parties. Thus, collaboration requires the resolving of differences and reaching a consensus. This process is generally referred to as policy reconciliation. Current solutions for pol...

The pharmaceutical supply chain is composed of multiple firms interacting to produce and distribute drugs in an uncertain environment. In this work, we develop and validate a multi-agent simulation of the supply chains associated with the pharmaceutical industry. We demonstrate that the operating norms of a particular industry can be accurately represented to create an industry-specific model c...

Crime is an economically important activity, sometimes called the “industry of crime”. It may represent a mechanism of wealth distribution but also a social and economic charge because of the cost of the law enforcement system. Sometimes it may be less costly for the society to allow for some level of criminality. A drawback of such policy may lead to a high increase of criminal activity that m...
