In the study, production, foreign trade, and competitiveness of countries, which have an important share in world aquaculture were examined. According to 2019 data shows that Chine Indonesia are most producers world. The set belonging 2010-2019 was used research. Revealed Comparative Advantage (RCA), Vollrath Relative Export Index (RXA), Trade (RTA), Competitiveness (RC), Import (RMA), Balance ...

We extend the trade restrictiveness index approach to the case of market imperfections and domestic regulations addressing them. We focus on standard-like non-tariff measures (NTMs) affecting cost of production and potentially enhancing demand by increasing product quality or reducing negative externalities. We apply the framework to the database of Kee et al. (2009) and derive ad valorem equiv...

Reliable evidence of trends in the illegal ivory trade is important for informing decision making for elephants but it is difficult to obtain due to the covert nature of the trade. The Elephant Trade Information System, a global database of reported seizures of illegal ivory, holds the only extensive information on illicit trade available. However inherent biases in seizure data make it difficu...

This article evaluates the extent to which the establishment of the Andean Free Trade Zone (AFTZ) has led to an improvement of intra-regional trade, as promised by open regionalism, without reducing extra-regional trade. Open regionalism is a dynamic process in which economic agreements serve as intermediate steps towards integration with the world economy. The calculations of ex post income el...

This paper studies the relationship between technology and trade specialisation and their dynamics. We use an index of revealed comparative advantage based on trade data to measure international trade specialisation and one based on patent data to measure international technological specialisation. The empirical analysis shows that the relationship between the two is not strong, thus con...rmin...

Published by Reporters Without Borders every year, the Press Freedom Index (PFI) reflects the fear and tension in the newsroom pushed by the government and private sectors. While the PFI is invaluable in monitoring media environments worldwide, the current survey-based method has inherent limitations to updates in terms of cost and time. In this work, we introduce an alternative way to measure ...

We propose a new index structure, called the HG-tree, to support content-based retrieval in multimedia databases. Our goals are twofold: increasing the storage utilization and decreasing the directory coverage of the index tree. The first goal is achieved by absorbing splitting if possible, and when splitting is n8ecessary, converting two nodes to three. This is done by proposing a good orderin...

the augmented gravity model was employed to determine iran's trading model and agricultural export directions in the case of cross section analysis in 2005 for 64 countries which are considered as iran's main export market. besides, another explanatory variable named trade conformity index (tci) was added to the model. this index was employed to identify iran's trading model. als...

We construct an example of supersymmetric Chern-Simons-matter theory with a matter field transforming as a singlet representation of the supersymmetry algebra, where the bosonic and fermionic degrees of freedom do not match. This is obtained as a non-relativistic limit of the N = 2 Chern-Simons-matter theory in 1+2 dimensions, where the particle and anti-particle coexist. We also study the inde...
