This paper addresses the linear ordering problem, which has been solved using different metaheuristics approaches. These algorithms have the common problem of finding a proper balance of the intensification and diversification processes; in this work we propose an iterated local search in which it is incorporated a Becker heuristic strategy for constructing the initial solution, and a search st...

We assess the impact of the geographic expansion of bank assets on the cost of banks’ interestbearing liabilities. Existing research suggests that expansion can both intensify agency problems that increase funding costs and facilitate risk diversification that decreases funding costs. Using a newly developed identification strategy, we discover that the geographic expansion of banks across U.S....

Diversification has become a common strategy of corporate risk management along with availing other potential benefits. The intent of this study is to identify and analyze the nature of relationship that exists between diversification and capital structure as well as profitability in Pakistan. For this purpose we use the 10 years’ (2000-2009) data of all the companies of chemical and food secto...

In this research we study the relative performance of investment strategies scrutinizing their behaviour in an ecological competition where populations of artificial investors co-evolve. We test different variations around the canonical modern portfolio theory of Markowitz, strategies based on the naive diversification principles and the combination of several strategies. We show, among others,...

Fluorescent building blocks: Tetracarboxyamides with a central fluorescent diaminoterephthalate unit were prepared from succinyl succinates following a combinatorial-like strategy. The 2,5-diaminoterephthalates (see scheme; PG=protecting group) possess four points of diversification and are introduced as new scaffolds for combinatorial chemistry.2,5-Diaminoterephthalates that possess four point...

This paper provides extensive evidence on portfolio characteristics of mutual funds and studies the relation between fund performance and the fund manager's investment strategy. The results show that neither momentum characteristics nor the valuation of stocks can explain differences in fund performance. However, the paper finds a negative firm-size effect that partly explains previous findings...

This paper describes a Diversification-Driven Tabu Search (D2TS) algorithm for solving unconstrained binary quadratic problems. D2TS is distinguished by the introduction of a perturbation-based diversification strategy guided by longterm memory. The performance of the proposed algorithm is assessed on the largest instances from theORLIB library (up to 2500 variables) as well as still larger ins...
