The study uses a survey distributed to a national consumer sample from the U.S., that is analyzed in a multivariate regression procedure. The analysis shows the importance of social factors for consumers’ viral intentions, integrating the socialization theory and market maven theory in the viral research. The results support a positive relationship between consumers’ socialization and communication related to advertising with their family and their viral intentions, showing that reference groups are important for viral advertising. This underlines the effect that the close interpersonal circle has on consumers’ involvement in viral communication. The statistical analysis also found a psychosocial characteristic, such as consumers’ market maven traits, to be positively related to viral intentions. Attitude toward the ad is also a significant influencer of viral intentions, as expected, showing that a positive impression about the ad is positively related to its viral potential. Overall, different social factors are found to be essential antecedents of viral ads, and future research can further focus on this topic, to create a social profile of consumers prone to participate in viral advertising.</p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art2-IACOBUTA Social dependency mentality in Romania - consequence of path dependence or result of social protection policies? 2019-02-21T18:52:28+02:00 Andreea Oana IACOBUTA andreea.iacobuta@uaic.ro Gabriel Claudiu MURSA ggggggg@mmmmmm.com <p>This paper discusses whether the social dependency mentality in Romania is a consequence of path (past) dependence (that is, the country’s cultural and historical inheritance), or of the failure of social protection policies implemented after 1990. By taking a deductive approach and using data from Eurobarometers and several international databases, as well as by conducting several statistical analyses, we first identify the socio-economic and institutional factors associated with social dependency mentality in former communist countries, today members of the EU. Drawing on the results obtained, we then characterize the situation in Romania and provide explanations on two levels: dependence mentality as cultural inheritance - hypothesis supported by sociological, psychological and cultural-anthropological studies - and dependence mentality as a consequence of the implemented social protection policies which did not solve the issue of poverty but rather speak about incoherence, lack of vision, populism etc. We conclude that social dependency mentality is associated with the burden of the past, but also with the level and quality of education and the government strength to implement policies and provide incentives for individual responsibility in a free market. The limitations in terms of data coverage do not allow us to establish the exact weight each of the factors has in explaining social dependency mentality and, consequently, further studies are necessary considering the importance this issue currently has in poverty reduction.</p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art3-SHOBANDE Export concentration and sectorial performance: a re-examination of the empirical evidence 2019-02-21T18:52:28+02:00 Olatunji A. SHOBANDE olatunji.shobande@yahoo.com <p><em>This paper examines to what extent export concentration can be tailored towards promoting economic growth in Nigeria. A deeper understanding of the interrelationship among various sectorial units, as well as the investment channel that better stimulates the economy is the thrust of this paper. As a consequence, the study wants to answer to the question whether it “is there any linkage between export concentration, and various sectorial output share (agricultural, manufacturing, and service sector) on growth performance?”. The methodology we made use of is a Vector Autoregressive (VAR) model for the various sectoral analysis of export concentration in Nigeria. The estimated results show that export concentration has an important role to play in driving economic growth and that this role emanates from the agricultural and manufacturing sectoral channels. These channels account for about 93 percent and over 3 percent respectively of the total variation of export concentration contribution to economic growth. The result also indicates that one standard deviation shock to export concentration results in a peak on agricultural sector quarterly after shock. As a result, the study recommends that government ought to make available incentive to the agricultural sector to further enhance the contribution of the sector to the economic growth in the Nigeria economy.</em></p> 2019-02-21T16:29:09+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art4-SIRGHI The deterministic model with time delay for a new product diffusion in a market 2019-02-21T18:52:28+02:00 Nicoleta SIRGHI nicoleta.sirghi@e-uvt.ro Mihaela NEAMTU mihaela.neamtu@e-uvt.ro Gabriela MIRCEA gabriela.mircea@e-uvt.ro Doriana RAMESCU doriana.ramescu@e-uvt.ro <p>The aim of this paper is to present and analyze a market through a nonlinear deterministic model. A firm launches a new product and devotes a fixed proportion of sales to advertising, while customers go through a three stage adoption process with some delay on the effect of advertisement. The mathematical model is described by three nonlinear differential equations with time delay, where the word-of-mouth and advertising effectiveness are taken into account. The variables consist of the number of non-adopters (unaware of the existence of the product or the number of people who have not repurchased it), the number of thinkers (the number of people who know about the product, but they have not yet purchased it) and the number of adopters (the number of people who have purchased the product). The time delays are introduced in both purchase decisions of the thinkers and repurchase decisions of the adopters as well. The positive equilibrium point is determined and the conditions for the asymptotic stability are provided, when there is no delay.&nbsp; When the delay is taken as bifurcation parameter the conditions for the existence of a Hopf bifurcation are given. The critical value of the delay is found where the asymptotic stability is lost. Numerical simulations and conclusions can be found in the last part of the paper.</p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art5-MADICHIE Economic diversification: imperative for trade and industrial policies in Nigeria 2019-02-21T18:52:28+02:00 Chekwube Vitus MADICHIE chekwubevitusmadichie@gmail.com Festus OSAGU fff@ooo.co Eze Anoke EZE eeee@eeeee.com <p>The sharp and continuous decline in crude oil prices since the mid-2014, along with the lackluster efforts at diversifying the sources of revenue and foreign exchange in the economy, incontrovertibly led to the recession that greeted Nigeria in the second quarter of 2016 as manifested by fiscal crisis. Hence this study examines the imperative of economic diversification in trade and industrial policies in Nigeria. In order to characterize the pattern of trade and industrial transformation in the diversification process, we adopted the augmented version of Kaldor’s first law which establishes a link between manufacturing output and economic growth. Based on annualized secondary time series, spanning from 1970 to 2015, obtained from the CBN statistical bulletin of various years, the study employed the contemporary econometric techniques of cointegration and error correction mechanism, within the framework of the Autoregressive Distributed Lag (ARDL) model as proposed by Pesaran et al (2001) in achieving its objective. The results show that manufacturing output, crude petroleum and natural gas production, as well as mining production have significant positive longrun impact on economic growth in Nigeria. This implies that economic diversification-based industrial policies will definitely bring about the desired economic outcomes in Nigeria. We therefore conclude that trade and industrial policies should be geared towards diversification of the economy.</p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art6-PAUNA Trading signals based on Fisher transform for algorithmic trading 2019-02-21T19:05:32+02:00 Cristian PĂUNA cristian.pauna@ie.ase.ro <p align="JUSTIFY"><span style="color: #000000;"><em>Trading and investment on financial markets are common activities today. A very high number of investors, companies, public or private funds are buying and selling every day with a single purpose: the profit. The common questions for any market participant are: when to buy, when to sell and when is better to stay away from the market risk. In order to answer all these questions, many trading strategies are used to establish the best moments to entry or to exit the trades. Due to the large price volatility, a significant part of the trades are made automatically today by computers using algorithmic trading procedures. For this particular field, special aspects must be met in order to automate the trading process. On this paper it will be presented one of these mathematical models used in automated trading systems, a method based on the price Fisher transform. It will be presented a general form of this method, the functional parameters and the way to optimize them in order to reduce the risk. It will be also revealed a method to build reliable trading signals with the Fischer function. Three different trading signal types will be explained together with the significance of the functional parameters in the price field. A code sample will be included in this paper to prove the simplicity of this method. Real results obtained with the Fisher trading signals will be also presented, compared and analyzed in order to show how this method can be implemented in algorithmic trading.</em></span></p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement## http://tjeb.ro/index.php/tjeb/article/view/TJEB-vol11-2018-iss1-art7-BANTA Adoption of a KPI solution for accounting area inside SAP system. An oil and gas company case study 2019-02-21T18:52:28+02:00 Viorel Costin BANȚA bantaviorel@gmail.com <p>Over the years, there has been a growing interest in ERP systems - in our SAP case. These IT systems have come up with a number of novelties in terms of unifying IT and business processes. This created the premise of essential changes in data management, sorting them across multiple categories, reporting them now much faster. In the case of this article, we have transformed the ideas from the business environment into an application meant to serve the accountants in terms of monitoring and reporting their activity to their superior level. Key performance indicators (KPIs) have been defined by the business environment according to the purpose for which they were created. This required a differentiation on skill levels, so that the results were conclusive and helped the business to manage the activity he was responsible for. We wanted to provide a complete framework for KPI management in the economic organization level by developing this application – Z-KPI tool, the results being useful to the heads of department in order to well manage their work, so that the targets assumed at the beginning of the year to be achieved. The entire application was developed in SAP system, using the latest technology - ABAP WebDynpro. The software application is now in production and the degree of use is high, because the SAP system is the core system in the company for which this case study was performed.</p> 2019-02-21T00:00:00+02:00 ##submission.copyrightStatement##
