Almost Stochastic Dominance and Efficient Investment Sets  [PDF]
Moshe Levy
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.23038
Abstract: A major drawback of Mean-Variance and Stochastic Dominance investment criteria is that they may fail to determine dominance even in situations when all “reasonable” decision-makers would clearly prefer one alternative over another. Leshno and Levy [1] suggest Almost Stochastic Dominance (ASD) as a remedy. This paper develops algorithms for deriving the ASD efficient sets. Empirical application reveals that the improvement to the efficient sets implied by ASD is substantial (64% reduction for FSD). Direct expected utility maximization shows that investment portfolios excluded from the ASD efficient set would not have been chosen by any investors with reasonable preferences.
The Macroeconomic Effect of Public Investment  [PDF]
Chen He
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.811086
Abstract: This paper establishes a VAR model and VEC model using the data of Chinese public investment, GDP, private investment and employment from 1997 to 2013 aiming to analyze the influence of Chinese public investment on GDP, private investment and employment through ADF unit root test, Granger causality test, Johansen co-integration test, impulse response function, variance decomposition and other empirical methods. Results show that there is a stable equilibrium relationship among Chinese public investment, GDP, private investment and employment in the long term; Public investment has a positive effect on GDP in the short term, which is not obvious even negative in the long term though; Public investment has a crowding out effect on private investment in the short term, while has a positive impact instead in the long term; The positive influence that public investment has on employment is very weak both in the short term and long term. For the stable and healthy development of social economy, the government should improve the efficiency of public investment by means of controlling the scale, optimizing the structure and strengthening the supervision of public investment; A series of policies should be introduced as well to encourage private investment at the same time.
General Closed-Form Solutions to the Dynamic Optimization Problem in Incomplete Markets  [PDF]
Moawia Alghalith
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.24054
Abstract: In this paper, we provide general closed-form solutions to the incomplete-market random-coefficient dynamic optimization problem without the restrictive assumption of exponential or HARA utility function. Moreover, we explicitly express the optimal portfolio as a function of the optimal consumption and show the impact of optimal consumption on the optimal portfolio.
An Alternative Method of Stochastic Optimization: The Portfolio Model  [PDF]
Moawia Alghalith
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.27123
Abstract: We provide a new simple approach to stochastic dynamic optimization. In doing so, we derive the existing (standard) results using a far simpler technique than the duality and the variational methods.
Generalized Stochastic Processes: The Portfolio Model  [PDF]
Moawia Alghalith
Journal of Mathematical Finance (JMF) , 2012, DOI: 10.4236/jmf.2012.22022
Abstract: Using the portfolio model, we introduce a general stochastic process that is not necessarily a diffusion/jump process and the random variable is not necessarily normally distributed.
Investing in China: Opportunities and Risks in the Future  [PDF]
Yunhua Liu
Journal of Financial Risk Management (JFRM) , 2012, DOI: 10.4236/jfrm.2012.11001
Abstract: Investment environment in China is changing due to the drastic change in world economic environment and the intrinsic evolution inside the Chinese economy. Although China is facing a series challenges for its further growth, a soft landing of the economy is expected. To meet the external and internal challenges and to overcome the constraints for further growth, China has to transit the growth pattern which will generate two areas of new demand, expansion of new industries for green economy and for resources saving goals and promoting the purchasing power of low income group. Fast urbanization and moving to the west are the other two major development opportunities. Risks and uncertainties in the coming time could come mainly from the slowdown of external demand growth, the appreciation of Chinese currency, the labor cost increase, domestic competition and product mimicking, resource supply constraints, and trade disputes.
Does Human Resource Management Help a Company’s Financial Operating Result?  [PDF]
Rob. C. H. van Otterlo
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.65031
Abstract:

Human Resource Management (HRM) is widely believed to have a positive effect on the performance of company. However, empirical proof of this is hard to come by. In this study, we try to establish a linkage between HRM and financial output of two case studies in the profit sector. To do this, we have developed a performance measurement system that is tailored to the specific needs of measuring HRM-performance in for-profit of company. Although we do not try to generalize the outcome of this study, it looks promising in the way that more case studies should be conducted using this specific performance measurement system. If nothing else, management and controllers could use the system to evaluate the performance of their HRM-tools.

The Impact of Direct Foreign Investment on Unemployment in Jordan  [PDF]
Mohammad Haroun Eid Al Amarat
Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.76078
Abstract: This study aimed at recognizing the size of direct foreign investment in Jordan and its impact on the rate of unemployment in Jordan. It also aimed at recognizing the constraints against the foreign investment. The study concludes that the low levels of these investments are attributed to the lack of regulating legislations that encourage foreign investment in Jordan. The study recommends the development of services and infrastructures; besides, the Jordanian concerned departments should prepare and disseminate the information on investment opportunities in Jordan.
Empirical Evidence on the Determinants of Cybersecurity Investments in Private Sector Firms  [PDF]
Lawrence A. Gordon, Martin P. Loeb, William Lucyshyn, Lei Zhou
Journal of Information Security (JIS) , 2018, DOI: 10.4236/jis.2018.92010
Abstract:
Investments in cybersecurity are critical to the national and economic security of a nation. There is, however, a strong tendency for firms in the private sector to underinvest in cybersecurity activities. This paper reports the results of a survey designed to empirically assess whether treating cybersecurity as an important component of a firm’s internal control system for financial reporting purposes serves as a driver for private sector firms to invest in cybersecurity activities. The findings, in this regard, are significantly positive. The study also shows that a firm’s concern over the risk of incurring a large loss due to a cybersecurity breach and the degree the firm treats cybersecurity investments as generating a competitive advantage are drivers of the level of private sector investment in cybersecurity activities. The implications of the empirical results for designing public policies to mitigate the tendency of private sector firms to underinvest in cybersecurity are also explored.
Beyond the No Free Lunch Principle: A New Combination of Arbitrage and Investment  [PDF]
Yi-Jang Yu
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.94046
Abstract: In the financial market, within both extremities of asset investment and arbitrage, there are sufficient rooms to contain something else other than speculation. The first aim of this study is thus to introduce a new sector which although cannot violate the common sense of “no free lunch” as can arbitrage, still is capable of surmounting general beliefs about the trade-off between risk and return that accompanies speculation. The second aim of this study is intended to reduce the ingredients of unfair games in the financial market.
