We determine the optimal dynamic investment policy for a mean quadratic variation objective function by numerical solution of a nonlinear Hamilton-Jacobi-Bellman (HJB) partial differential equation (PDE). We compare the efficient frontiers and optimal investment policies for three mean variance like strategies: pre-commitment mean variance, time-consistent mean variance, and mean quadratic vari...

This article highlights the importance of investors’downside-risk concerns, and examines optimal investment behaviors in a dynamic downside-risk framework. The authors does not only derive an analytical expression of investors’ optimal behaviors, but also provide economic insights of the properties of the downside risk measure and optimal investment strategies using comparative statics. It shed...

In this paper we develop a framework for optimal investment decisions for insurance companies under unhedgeable risk. The perspective that we choose is from an insurance company that tries to maximise the stream of dividends paid to its shareholders. The policy instruments that the company has are the dividend policy and the investment policy. The insurance company can continue to pay dividends...

5 We determine the optimal dynamic investment policy for a mean quadratic variation ob6 jective function by numerical solution of a nonlinear Hamilton-Jacobi-Bellman (HJB) partial 7 differential equation (PDE). We compare the efficient frontiers and optimal investment poli8 cies for three mean variance like strategies: pre-commitment mean variance, time-consistent 9 mean variance, and mean quad...

We examine the problem of a risk-neutral investor who has to choose among two alternative projects of different scales under output price uncertainty. We show that as soon as investment in the smaller scale project is sometimes optimal, the optimal investment strategy is not a trigger strategy and the optimal investment region is dichotomous. Whenever the investor has the opportunity to switch ...

Calculating total cast of bank resources procurement methods which include current -free loan deposit, saving interest-free loan deposit, regular and net short-term investment deposit, long-term investment deposit and surety bond cash deposit and presenting their optimal integration require precise scientific studies. Hence, this study is an attempt to know which methods are the best optimal in...

The study of memory for event duration in pigeons has, for the most part, centered on an unusual behavioral phenomenon and an interesting theoretical explanation for it. A typical experiment on memory for event duration involves trials initiated by a sample stimulus that is either short or long in duration (e.g., 2 vs. 10 sec of houselight) and that is later followed by the simultaneous present...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

in the presence of uncertainty about what a country can be good at producing, there can be great social value to discovering costs of domestic activities, because such discoveries can be easily imitated. two failures of the laissez – faire outcome are being highlighted: there is too little investment and entrepreneurship ex ante, and too much production diversi-fication ex post. optimal policy ...

This study analyzes an optimal investment strategy for information security (IS) for a profit-maximizing online monopoly when it is facing attacks from cyber criminals by considering a network security theoretical model with time-varying characteristics. The intangible profit of security investment is transformed into a measurable sales benefit by using a successful entry ratio that links the r...
