The continuous rise of the world’s population has made food security a major point of the global agenda, with fisheries providing a key source of nutrition, especially in developing countries. Ensuring their health is key to maintain the availability of the resource, but its effect over accessibility is yet unclear. In this paper, we discuss the relevance of stock health for ensuring the price accessibility of the resource. A Least Square Dummy Variable panel model is proposed for bluefin tuna prices, with a biological explanatory component, and dummy variables reflecting changes in fishing trends. Both have proven to be significant to explain annual price variations, with improvements in stock health achieving price reductions.

This research was aimed to determine theforms of the non-tarifbarrier and its impact to the Indonesian shrimp export demand to the European Union (EU), beside the other factors as constructor of demand function. This research used secondary data (lime series) during 23 years (1984-2006): shrimp export volume (Qd), shrimp export price (Px), domestic shrimp price (Pd), crab export price (Pk), exchange rate from the importing countries, and commerce regulations which is peiformed by EU as dummy variables. The data collected from DKP, BPS, Depdag, internet, and other relevant institutions. Peculiarly, the dummy variable grouped into 6 groups: RASFF (DI), contaminant (D2), certain substances & residues (D3), health conditions & food hVf!iene rules (D4), HCCP (D5), and marketinf! standards (D6).This research used the multiple regression analysis model, with the tolerant time (!gg) I year from tfor several dummy variables. Analysis were conducted at 6 markets: UE as a whole, Dutch, United Kingdom (UK), French, Germany, and Belgia and Luxemburg. Testing of the classical assumptions conducted by the econometric criterions is covering the economic and statistic criterions. The estimation of the regression parameters conducted by the smallest square method (ordinarv least SQuare. OLS) and model repaired as the effect of existence of the first order autocorrelation by a comand "auto". The equation model related to the Coob-Douglas model, was transformed into the natural logarithm model in order to easiZv analyzed in package program of statistics.Result of the analysis indicated that the commerce regulations applied by the EU, which its vary to each state, entirely has the negative impact to the Indonesian shrimp export to the UE, except D4 for the UK that shown the positive impact. Several regulations known newly indicated the effect which itsformed into Jgg or its impact is newly felt I year after the regulations enter into force. Thefact strengthen the assumption that applying of commerce regulations by the UE can be the disguised restriction to trade, in this case included to the non tarifbarrier. The sixth groups of the regulationswere very related to the food security and traceability aspect, or in its bearing with the WTO agreements were very related to the SPS and TBT aspect. This invention also strengthen the assumption that non-tarif barrier which newly developed by the advanced countries to control the importation from the other countries were deal with the food security and traceability aspect, or the SPS and TBT aspect. The quantitative non- tarif barrier, example import quota or embargo, were rarer in used. Ap-parently, the EU doesn't wishtoooutspokenin theeffort to control its commerce with the other countries.Realizedor not, in thepresentnon-tarif barrier haveimportantposition to determinewhetheror not thefluent of theinternational trade

The main objective of the study is to empirically examine the relationship between domestic terrorism, investment and economic growth. The study finds the implication of domestic terrorism on investment and growth among 26 Muslim and 14 Christian developing countries. Data regarding the incidence of terrorism are obtained from Global Terrorism Database (2015). While, economic data are obtained from World Development Indicators (WDI, 2015). The data on external and internal conflict have been extracted from Global Conflict Risk Index (GCRI, 2015) for the time period 1990-2015. Ordinary least square (OLS), feasible generalized least squares (FGLS) and system generalized method of moment (SGMM) approaches were applied to ensure robust results with different specification of models by using dummy variable. The value of Dummy variable is 1, if country is Muslim otherwise 0. For all specifications, it is confirmed that increase in domestic terrorism will decrease the level of investment directly, but the percentage decrease in investment due to terrorism is high among Muslim as compared to Christian developing economies. The results indicate the public policy efforts to mitigate the loss of private investment which can be done initially by public investments to ensure public safety. Keywords: OLS, FGLS, SGMM, Domestic Terrorism, Muslim and Christian Developing Countries.

Although global food production has consistently kept pace with population growth, the gap between food production and demand in certain parts of the world is likely to remain. More than 800 million people in developing countries lack access to a minimally adequate diet. Continued productivity gains are essential on the supply side, because global population will increase by 73 million people a year over the next two decades. In this article we assess the current global food situation, look at the prospects through to the year 2020, and outline the policies needed to achieve food security for all. Emphasis is on the role that agricultural biotechnology might play in reaching this goal.

Renewable energy is being increasingly touted as the “fuel of the future,” which will help to reconcile the prerogatives of high economic growth and an economically friendly development trajectory. This paper seeks to examine relationships between renewable energy production and economic growth and the differential impact on both developed and developing economies. We employed the Fully Modified Ordinary Least Square (FMOLS) regression model to a sample of 20 developed and developing countries for the period 1995–2016. Our key empirical findings reveal that renewable energy production is associated with a positive and statistically significant impact on economic growth in both developed and developing countries for the period 1995–2016. Our results also show that the impact of renewable energy production on economic growth is higher in developing economies, as compared to developed economies. In developed countries, an increase in renewable energy production leads to a 0.07 per cent rise in output, compared to only 0.05 per cent rise in output for developing countries. These findings have important implications for policymakers and reveal that renewable energy production can offer an environmentally sustainable means of economic growth in the future.

Undoubtedly, entrepreneurial knowledge is a prerequisite for the survival of every business organization. To this, the contribution of Small and Medium Enterprises (SMEs) in the socio-economic development in most developing economies cannot be underestimated. Both developed and developing countries are living testimonies of their contributions to their nation’s growth and development. However, extant literature shows that as competition and innovation intensify in the global business market, many SMEs in developing countries are constrained by external forces that hinder the sustainability of these businesses.   Hence, this paper aims to find out the mitigating factors warranting SMEs’ sustainability from the viewpoint of entrepreneurs and business owners, particularly in the manufacturing sector of Ghana, a Sub-Saharan Africa region. To achieved this objective, the study deployed a simple random sampling technique with 370 valid responses through a structured questionnaire for the analysis. Relying on PLS-SEM (partial least square and structural modeling) with the aid of ADANCO 2.2.1 software version revealed that factors such as financial challenges, technology; market penetration & acceptability; and research & development are barriers facing SMEs sustainability in the Ghanaian manufacturing sector. This study would be beneficial to entrepreneurs and business owners of SMEs in most developing countries and provide deeper insight into the SME literature at large. This study would further strengthen SME entrepreneurs and business owners to fully devise strategies that can help them to override such migrating challenges and equipped them to effectively stay competitive in the long term for the firm’s growth and survival. The limitation and future research directions are equally presented in the paper.
