Allocation Decisions

Liquidity and volatility are the two barometers that allow stock markets to appreciate in terms of attractiveness, profitability and efficiency. Several macroeconomic and microstructure variables condition the level of liquidity that directly impact the asset allocation decisions of different investor profiles − institutional and individuals − and therefore the dynamics of the market as a whole. Volatility is the regulatory component that provides information on the level of risk that characterizes the market. Thus, the appreciation of these two elements is of considerable help to fund managers looking to optimize their equity pockets. In this work, we will use the liquidity ratio as a proxy variable for the liquidity of the Moroccan stock market, to estimate the indicators and factors that determine its short- and long-term variability. The appropriate econometric method would be to estimate an error correction vector model (ECVM) which has the property of determining the long- and short-term relationships between the variables. The volatility of the MASI index will be the subject of a second estimate to capture the shape of the function of its evolution.

The Impact

The aim of this meta-analysis was to review the impact of a Paleolithic diet (PD) on selected health indicators (body composition, lipid profile, blood pressure, and carbohydrate metabolism) in the short and long term of nutrition intervention in healthy and unhealthy adults. A systematic review of randomized controlled trials of 21 full-text original human studies was conducted. Both the PD and a variety of healthy diets (control diets (CDs)) caused reduction in anthropometric parameters, both in the short and long term. For many indicators, such as weight (body mass (BM)), body mass index (BMI), and waist circumference (WC), impact was stronger and especially found in the short term. All diets caused a decrease in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), albeit the impact of PD was stronger. Among long-term studies, only PD cased a decline in TC and LDL-C. Impact on blood pressure was observed mainly in the short term. PD caused a decrease in fasting plasma (fP) glucose, fP insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) and glycated hemoglobin (HbA1c) in the short run, contrary to CD. In the long term, only PD caused a decrease in fP glucose and fP insulin. Lower positive impact of PD on performance was observed in the group without exercise. Positive effects of the PD on health and the lack of experiments among professional athletes require longer-term interventions to determine the effect of the Paleo diet on athletic performance.

Allocation Decisions

This paper investigates the effect of fund managers' performance evaluation on their asset allocation decisions. We derive optimal contracts for delegated portfolio management and show that they always contain relative performance elements. We then show that this biases fund managers to deviate from return-maximizing portfolio allocations and follow those of their benchmark (herding). In many cases, the trustees of the fund who employ the fund manager prefer such a policy. We also show that fund managers in some situations ignore their own superior information and "go with the flow" in order to reduce deviations from their benchmark. We conclude that incentive provisions for portfolio managers are an important factor in their asset allocation decisions.

Allocation Decisions

Using survey data, we analyze institutional investors’ expectations about the future performance of fund managers and the impact of those expectations on asset allocation decisions. We find that institutional investors allocate funds mainly on the basis of fund managers’ past performance and of investment consultants’ recommendations, but not because they extrapolate their expectations from these. This suggests that institutional investors base their investment decisions on the most defensible variables at their disposal and supports the existence of agency considerations in their decision making.

The Impact

The present article seeks to critically probe Gandhi’s civilisational view of Indian society and politics both from his few articulate and many hidden statements at different stages of his life. His civilisational view is, therefore, analysed from a variety of perspectives: its origin, direction, advocated methods and long-time impact on Gandhian thought, philosophy and activities. It is presumed that such an analysis of Gandhi’s political philosophy with special reference to his civilisational view may clarify some of the mysteries associated with his much cited and often criticised ‘strategies’ of political activity. The article has three parts. The first dwells on the background of Gandhi’s civilisational critique and touches on some of its contents from the political standpoints. The second probes into the many meanings of civilisational politics both from Gandhi’s articulate and hidden statements on the subject. The third reviews the impact of Gandhi’s civilisational politics on the course and strategy of his political action, and its legacy for the future. The underlying idea is that satyagraha in the Gandhian philosophical context is most intelligible when viewed from the short- and long-term perspectives of civilisational politics.

The Impact

With the steady growth in the data set on the COVID-19 pandemic, empirical works that employ novel and yet appropriate statistical techniques to corroborate previous findings of the pandemic and its consequences on financial markets are necessary. This paper examined the impact of COVID-19 information flow on the Islamic and conventional equities within the short-, mid-, and long-term horizons to assess possible diversification prospects in the era of the pandemic. To the studied equities markets, a novel technique based on a denoised frequency-domain entropy paradigm was applied. The operability of entrenched market dynamics in the long-term horizon of the COVID-19 pandemic period is reinforced by the results. The findings divulge diversification opportunities between Islamic and conventional equities in the short- and mid-term periods of the COVID-19 pandemic. The risks on equities from Japan or Bahrain could be diversified by equities from Jordan in the short-term, while in the intermediate-term stocks from Japan could diversify with the UAE and USA equities. The results imply that it is imperative for investors and fund managers to employ portfolio management techniques that show how to use benefits together with risk prevention and management across distinct time scales.

Research on human resources, foreign direct investment and economic development are important issues in assessing the effectiveness of employment as well as attracting foreign direct investment (FDI) in the economy. In this study, the author analyzes the impact of human resource factors and FDI on economic growth in Vietnam from 1990 to 2017. By regression analysis based on the ARDL model, the result shows FDI has only a positive effect on economic growth in the short term but has the opposite effect in the long term. At the same time, unemployment rates have the opposite effect on economic growth in the short term. Average life expectancy does not affect economic growth in both the short and long term. From this result, the author also offers some suggestions for economic development in both the short and long term.

AbstractBackgroundMass drug administration (MDA) of ivermectin for onchocerciasis has been disrupted by the SARS-CoV-2 (COVID-19) pandemic. Mathematical modelling can help predict how missed/delayed MDA will affect short-term epidemiological trends and elimination prospects by 2030.MethodsTwo onchocerciasis transmission models (EPIONCHO-IBM and ONCHOSIM) are used to simulate microfilarial prevalence trends, elimination probabilities, and age-profiles of Onchocerca volvulus microfilarial prevalence and intensity, for different treatment histories and transmission settings, assuming no interruption, a 1-year (2020) or 2-year (2020–2021) interruption. Biannual MDA or increased coverage upon MDA resumption are investigated as remedial strategies.ResultsProgrammes with shorter MDA histories and settings with high pre-intervention endemicity will be the most affected. Biannual MDA is more effective than increasing coverage for mitigating COVID-19’s impact on MDA. Programmes which had already switched to biannual MDA should be minimally affected. In high transmission settings with short treatment history, a 2-year interruption could lead to increased microfilarial load in children (EPIONCHO-IBM) or adults (ONCHOSIM).ConclusionsProgrammes with shorter (annual MDA) treatment histories should be prioritised for remedial biannual MDA. Increases in microfilarial load could have short- and long-term morbidity and mortality repercussions. These results can guide decision-making to mitigate the impact of COVID-19 on onchocerciasis elimination.

The Impact

Numerous studies have used agency theory (Jensen and Meckling, 1976) and capital scarcity theory (Oxenfeldt and Kelly, 1969) to explain franchising motivations. Although both theories may in part account for why firms choose to franchise, past studies have not seriously considered the potential relationship between franchising and capital structures. Using Blinder–Oaxaca decomposition analysis, this study examined the impact of franchising on short- and long-term debt leverage. The final sample included 191 restaurant firms from 1980 to 2015. Sixty-five firms were non-franchise firms, while 126 firms engaged in the franchising business. The results of the Blinder–Oaxaca decomposition analysis showed that franchising has a significant effect on decreasing long-term debts and confirmed that franchising plays an important role as an additional source of long-term capital. Consequently, the capital scarcity theory is supported as one aspect of long-term debt leverage. However, franchise restaurant firms have larger short-term debt than non-franchise firms, although it is merely marginally significant. This contradicts capital scarcity theory but is in accordance with some past studies (e.g. Norton, 1988; 1995). This implies that franchisors constantly need short-term capital to support franchisees.

The Impact

The purpose of this longitudinal study was to identify the short- and long-term impact of business communication education on students’ skill developments and performance outcomes. Nearly 400 students at an AACSC International–accredited business college participated in the study during their sophomore and senior years. The findings indicate that the business communication course helped students develop good skills in writing reports, solving problems, working in teams, communicating orally, and using Internet technologies for both the short term (sophomore year) and the long term (senior year). More than 95% of the students reported achieving As and Bs on written assignments, company-analysis reports, problem-solving assignments, and oral presentations in their sophomore, junior, and senior years. However, the long-term effect was statistically less significant than was the short-term effect, although both were within the same positive range.

The Impact

The World Health Organization (WHO) has reported that each year, 1.35 million people worldwide die in traffic accidents, 20 to 50 million people are injured, and many of those who are injured are disabled. This article uses time-series data for the period 1970 to 2018 in Turkey short- and long-term social economic variables between the number of road accidents, energy consumption, gross domestic product per capita, vehicle kilometers traveled, number of motor vehicles, divided road length, and population growth to investigate the causal relationship. In the analysis, the vector error correction model (VECM) and the autoregressive distributed lag (ARDL) model were used for the short and long term, respectively. The results show that a 1% increase in the number of motor vehicles increases the number of accidents by 2.83% in the long term and has a positive relationship with traffic accidents. It has been determined that a 1% increase in the population increases the number of accidents by 9.43% in the short term and has a positive relationship with traffic accidents. It has been observed that a 1% increase in the length of the divided highway (LNDR [-2]) reduces accidents by 1.21% in the short term and there is a negative relationship between energy consumption and divided roads. This result supports the decision of the administrators in the country to construct a divided road.
