In the last years, the theory of numerical methods for system of non-stiff and stiff ordinary differential equations has reached a certain maturity. So, there are many excellent codes which are based on Runge–Kutta methods, linear multistep methods, Obreshkov methods, hybrid methods or general linear methods. Although these methods have good accuracy and desirable stability properties such as A...

There are n individual assets and k of them are to be sold over two stages. The first-stage prices are known and the second-stage prices have a known distribution. The sell or hold problem (SHP) is to determine which assets are to be sold at each stage to maximize the total expected revenue. We show that SHP is NP-hard when the second-stage prices are realized as a finite set of scenarios. We a...

The impact of financial leverage on firm investment is one of the most important issues in corporate finance. Debt overhang reduces the incentives of shareholder–management coalition in controlling the firm to invest in positive net-present-value investment opportunities. On the other hand, firms without debt in their financial structure face with a new problem known as over-investment. T...

top 20 ETFs by assets (with a combined total of $541 billion investor dollars) represent more than half of total equity ETF assets, and 17 of those 20 passively track traditional indices. The other three, representing $34 billion in assets, follow dividend strategies.2 invested in passive index funds (all U.S. and world equity mutual funds), but by November 2012, that number had risen to roughl...

Product Line Engineering (PLE) advocates the development of applications by reusing a set of software assets belonging to a given domain. Important research efforts have been devoted to the description of commonalties and variabilities among these assets yielding requirements engineering techniques such as feature modeling or use case variants. However, current product derivation techniques, wh...
