Abstract:
In order to construct an investment portfolio, it is crucial to select risky assets and arrange the weights to each asset. This article selects 6 stocks to compose the portfolio and compare their performances under 5 constraints that are always considered in real life by using Markowitz Model and Index Model. These two models would produce different investment portfolios as they take different factors of stock into account. By calculating the maximal return rate determined by Sharpe ratio, and the minimal risk rate determined by standard deviation, comparing the two models and conclude which m

Abstract An advanced LIGO and Virgo’s third observing run brought another binary neutron star merger (BNS) and the first neutron-star black hole mergers. While no confirmed kilonovae were identified in conjunction with any of these events, continued improvements of analyses surrounding GW170817 allow us to project constraints on the Hubble Constant (H 0), the Galactic enrichment from r-process nucleosynthesis, and ultra-dense matter possible from forthcoming events. Here, we describe the expected constraints based on the latest expected event rates from the international gravitational-wave net

Abstract:
We study a closed-loop supply chain involving a manufacturing facility and a remanufacturing facility. The manufacturer satisfies stochastic market demand by remanufacturing the used product into “as-new” one and producing new products from raw material in the remanufacturing facility and the manufacturing facility, respectively. The remanufacturing cost depends on the quality of used product. The problem is maximizing the manufacturer’s expected profit by jointly determining the collected quantity of used product and the ordered quantity of raw material. Following that we analyze the model wi

In this paper, we consider the problem of maximizing the expected discounted utility of dividend payments for an insurance company taking into account the time value of ruin. We assume the preference of the insurer is of the CRRA form. The discounting factor is modeled as a geometric Brownian motion. We introduce the VaR control levels for the insurer to control its loss in reinsurance strategies. By solving the corresponding Hamilton-Jacobi-Bellman equation, we obtain the value function and the corresponding optimal strategy. Finally, we provide some numerical examples to illustrate the resul

ABSTRACTRichness of subject-verb agreement is implicit in the functional compensation interpretation of variable second person /-s/ in Puerto Rican Spanish (PRS). Because /-s/ is not variable in Madrid Spanish (MS), richer agreement is assumed, and a lower rate of pronominal expression is expected. Central to this interpretation are effects associated with ambiguous marking of person on finite singular verbs. Although an increase of pronominal expression correlates to ambiguous marking for PRS speakers, a similar result has not been reported for MS speakers. Nonetheless, a varbrul analysis yie

We examine whether sensitivities to cash flow and discount rate risk in down markets explain the investment effect, in which low-investment stocks earn higher expected returns than high-investment stocks. We show how productivity and financing constraints asymmetrically impact the systematic risk of low-investment and high-investment firms, conditional on market state. Our evidence is consistent with both productivity constraints and financing constraints as explanations for the investment effect, but, contrary to expectations, more when prices are rising than falling.

Artificial intelligence plays an indispensable role in improving productivity and promoting social development, and causal discovery is one of the extremely important research directions in this field. Acyclic directed graphs (DAGs) are the most commonly used tool in causal modeling because of their excellent interpretability and structural properties. However, in the face of insufficient data, the accuracy and efficiency of DAGs learning are greatly reduced, resulting in a false perception of causality. As intuitive expert knowledge, structural constraints control DAG learning by limiting the

The goal is to maximize expected social welfare while maintaining that the allocation satisfies proportionality in expectation.

From these constraints, we generate sky maps above 40 EeV expected from a catalog that comprises 410,761 galaxies out to 350 Mpc and provides a near-infrared flux-limited sample to map both stellar mass and star formation rate over

Lifetime uncertainty represents an additional risk that affects intertemporal choice, because consumers may live longer than expected and run the risk of exhausting the resources accumulated for retirement. Lifetime uncertainty introduces an incentive to consume earlier in life because consumers discount future utility at a higher rate.
