The purpose of the study was to establish social protection mechanisms and systems that increase employee satisfaction in armed conflict societies. The study employed a qualitative research methodology, where semi-structured interviews were employed as the main data collection instrument. Data was collected from 50 (fifty) participants who were selected using the snow balling technique. The study established that social protection mechanisms which can be employed to mitigate social injury or damage and increase job satisfaction among employees in armed conflict societies include subsidized medical/health aide facility, counseling services, provision of security services for workers, in kind assistance, family feeding, social insurance and labour market intervention such as provision of jobs on infrastructure projects for cash or food. The study concluded that employer funded social protection systems play a critical role in boosting job satisfaction among workers in armed conflict areas. Social protection systems that address workers’ needs boost job satisfaction, motivation, commitment and loyalty among employees working in war torn areas. It was recommended that organizations should design various employer funded social protection mechanisms which can address workers’ needs.</p> Takupiwa Nyanga, Rosemary Sibanda ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/3.0/ https://www.tjeb.ro/index.php/tjeb/article/view/333 Wed, 30 Dec 2020 00:00:00 +0200 Asymmetric impact of inflation on foreign direct investment in Nigeria: an application of the Non-Linear Autoregressive Distributed Lag (NARDL) model https://www.tjeb.ro/index.php/tjeb/article/view/338 <p>In the last two decades, Nigeria has observed sporadic FDI inflows. The study aims to examine the asymmetrical effect of inflation on FDI inflows in Nigeria. Utilizing the ARDL and non-linear ARDL frameworks, the research discusses the impact of inflation and the exchange rate on FDI inflows in Nigeria between 1981 and 2018. The results of the study affirm the asymmetric linkage between inflation and FDI inflows during the study period. The finding established that the exchange rate plays a substantial role in increasing inflows of FDI in Nigeria. Moreover, the downside and upward trends of inflation decrease FDI inflows in the long and short term. Past studies have identified the aggregate effect of inflation, which can include limited knowledge on the phenomenon, in order to assess FDI inflows. The nonlinear method adopted points out that all forms of variations (i.e., upside and downside) of independent variables may have a significant and different effect on FDI inflows. The non-linear linkage between FDI and inflation may be critical to constructing a long-term strategy. Based on these findings, recommendations are suggested.</p> Tomiwa Sunday Adebayo, Gbenga Daniel Akinsola, Victoria Olanrewaju Olushola, Abisoye Abolaji ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/3.0/ https://www.tjeb.ro/index.php/tjeb/article/view/338 Mon, 30 Dec 2019 00:00:00 +0200 Petroleum Pump Price and Consumer Price Index in Nigeria: A case for or against Total Subsidy Removal – Panel Dynamic Analysis https://www.tjeb.ro/index.php/tjeb/article/view/335 <p>This study investigated the impact of petroleum pump price (PPP) on consumer price index (CPI) in Nigeria between 2000 and 2019, in order to have empirical support for or against total removal of subsidy on PPP. Three pump prices: prices of petrol, diesel and kerosene, were used to represent PPP. The economy was sub-divided into four: manufacturing; transportation; food; and domestic activities. Monthly Data were collected from both the NBS and CBN bulletins of different series. CPI was made the dependent variable and PPP, the independent variable. After the usual stationarity test, CPI was stationary at level while others were stationary at first difference. This informed the study to employ panel pooled mean/ARDL cointegration technique, which separated the impact into short and long run periods. Findings in the short run revealed that, the price of petrol had significant direct impact on consumer price in the short run. While these prices had no significant impact in the long run period, the price of kerosene indicated a significant inverse impact on consumer price in the short run but positive in the long-run. Results of cross-section short run coefficient revealed that prices of petrol and diesel had significant positive effect on manufacturing sector of the economy. The study, therefore suggests that, the government should remove subsidy totally on petrol and kerosene prices and reinvest the surplus into the economy, mostly in revamping the refineries. Also, Prices of alternative products to kerosene should remain stable to further reduce domestic use of kerosene in the economy.</p> Abdurrauf Babalola, Tunde Jibril Salau ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/3.0/ https://www.tjeb.ro/index.php/tjeb/article/view/335 Wed, 30 Dec 2020 00:00:00 +0200 Portfolio Selection During Crises Using Principal Component Analysis https://www.tjeb.ro/index.php/tjeb/article/view/342 <p>The current Covid-19 crisis, that debuted as an exogenous shock, has determined overreaction and herding among investors, as well as efficiency breaches and alterations within the Gaussian characteristics of returns’ distributions by generating strong asymmetries. Under such circumstances, the – econophysics approached – correlation structure within the market has been affected to an uncertain extent. Within these conditions, the problem of optimal portfolio selection becomes a subject of interest even for professional investors who tend to seek refuge towards developed, mature economies and quality assets. The Principal Component Analysis manages to offer a considerably useful tool for the allocation problem, by reducing dimensionality and, at the same time, by being able to account for the “unobservable risk” hidden within the market. The method is able to provide well-diversified portfolios, by explaining the systematic risk component within the analyzed returns series. The paper analyzes the ability of the PCA method, used aside with a KMO Test, to provide high rates of return even during turbulent, extremely volatile periods, such as the current one. The results show that the PCA weighted portfolio manages to achieve a rate of return higher than the one generated by an equally weighted “market portfolio”, proving therefore the robustness of the method.</p> Roxana Ioan ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/3.0/ https://www.tjeb.ro/index.php/tjeb/article/view/342 Thu, 31 Dec 2020 00:00:00 +0200 The effects of the pandemic crisis on self-employed https://www.tjeb.ro/index.php/tjeb/article/view/340 <p>The purpose of this research is to present the changes and trends that have taken place in the labor market following the pandemic crisis. The pandemic has disrupted economies around the world, and the economic consequences are enormous. The purpose of this paper is to identify the changes and transformations that have taken place in the Israeli self-employment market and to examine the effects of the pandemic crisis on these changes. Changes in the economic outlook were manifested in a variety of aspects, such as a significant reduction in the flow of government investment and credit to the economy, developing and expanding employment opportunities, and providing greater space for the involvement of private parties in large parts of the economy, which was reflected, among other things, in increasing the number of public sector employees. As a result of this crisis, more and more workers can be seen switching to self-employment or "contract work", on the one hand, these forms of work are characterized by a weakening of the mutual commitment between the worker and his workplace and, in some cases, they violate workers' social rights, but allow for high professional flexibility. At present, the trend is referred very much to the change in the nature of traditional work. This paper leads to conclusions about the development of self-employment while formulating a unique picture of the effects of the pandemic crisis on the Israeli labor market.</p> Iyad Snunu ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/3.0/ https://www.tjeb.ro/index.php/tjeb/article/view/340 Sat, 30 Jan 2021 00:00:00 +0200
