From the beginning of the 21st century, big changes in LAC's trade patterns have been observed. The article contains possible explanation of them. The analysis is based on the ECLAC (Economic Commission for Latin America and the Caribbean) data. Merchandise trade between China and LAC grew significantly over the period from 2000 to 2013. In 2013, the value of merchandise exports from China was higher than from the EU-28 in the case of 12 LAC countries. Chinese imports of goods surpassed the European ones in five countries in the region. In order to increase its exports of manufactured goods and imports of natural resources and agricultural commodities, China combines trade arrangements with foreign aid policy. Besides, a rapid development of bilateral diplomatic ties between China and LAC is observed. The EU-LAC trade relations have worsened during the last decade mainly due to financial crisis and development of the EU-Asia trade relations.展开更多

Current automated negotiation models assume that users know the value of the product or service they want to buy and provide their agents with a reservation price, and the agents make offers and reach agreements with other agents according to this reservation price. However, in real world electronic marketplaces users probably do not know the exact value of the item, which is in terms of price, and the reservation price they set to their agents only means the maximum price they are willing to pay for the item. In this paper, we propose a negotiation model to deal with the valuation problem. The shopping agent in our model can deliberate the market price and the seller agent’s reservation price from public available information and the seller agent’s proposals. Also in order to conform with the real world negotiation conditions, we introduce negotiation features of real world human shopping such as multiple sellers, valuation, ultimatum, and learning from available information, etc. into our model.展开更多

At a time of economic crisis, Slovakia acceded to the adoption of a common currency--the euro. Prior to the adoption of the euro, apprehensions were raised due to currency decreased export from Slovakia to countries V4. In this article, author analyses the mutual foreign trade of Slovakia with countries of V4 for all commodities in standard international trade classification (SITC) codes. The analysis covers the time before the adoption of the euro from 2004 to 2008 and after the adoption of the euro in the years from 2009 to 2013. It compares the percentage change over the previous year, the balance of foreign trade, and foreign trade turnover. The same analysis is also done for the period prior to the adoption of the euro as a whole and after the adoption of the euro. In the calculations, data from UN Comtrade Database were used, which are indicated in USD. The results indicate that in the transition to the common currency, the euro did not mean for Slovakia worsening trade with V4 countries. Economies of these countries have long been linked and even the possibility of its own monetary policy does not endanger Slovakia's export to these countries.展开更多
