Security, in respect of information technology (IT) systems, refers to the fact that protection goals are achieved in spite of intelligent attacks. This paper commences with a brief discussion of the term security in the context of IT systems. Of particular importance is the broadening of the term's meaning which has resulted from the development and more widespread deployment of IT, in particu...

We model agents’ incentives to invest in production of export goods when governments are commitment constrained with respect to their trade obligations. Once irreversible investments have been undertaken, the governments have incentives to renegotiate the tariff rates to higher values. The renegotiations are costly; the greater the tariff rate adjustment, the greater the expenses. We find that ...

The main aspects of the building process of the Euro-Mediterranean security system are assessed in this article with the tools of analysis of the regional security systems. The Mediterranean security project is also compared with other forms and cases of regional security system. The presence of other multilateral initiatives on Mediterranean security is pointed out as a strategic tool for the ...

We study the endogenous formation of free trade agreements (FTAs) in a symmetric three-country model with vertically related markets characterized by Cournot competition. We analyze the coalition-proof Nash equilibria in an FTA formation game in which each country forms an FTA with one, both, or none of its trading partners. We show that multilateral free trade is the unique stable equilibrium ...

This paper analyses the distribution of total aid and aid to the social sectors between 2009 and 2011. Its key findings are four-fold. First, despite the stated objectives of donors, total aid disbursements are broadly neutral, favouring neither the most deprived nor relatively well-off countries. Second, the pattern of social sector aid disbursements follows those for total aid. Third, the aid...

For any multilateral matching problem with dichotomous preferences, in the sense that agents are indifferent between all acceptable teams, there exist some strategy proof, individually rational and efficient mechanisms. Moreover some random matching mechanisms simultaneously satisfy the three crucial desiderata of mechanism design: efficiency, fairness and strategyproofness, which typically con...

We show our approach in developing an identity management system with respect to multilateral security. After examining digital pseudonyms and credentials as basic concepts of such a system, we give an introduction to technologies for multilateral security and describe an architecture which enables multilaterally secure communication. By means of di€erent scenarios we show requirements of an id...

The contemporary multilateral trading system comprises members ranging from highto very low-income countries; this range has a bearing on the operations of the multilateral trade regime. Presence of a large number of low-income members is the new systemic reality. Special and differential treatment (SDT) has operated for the developing economies, principally for the small, low-income ones, for ...

Events of the past two decades have generated increasing concern about the direction of the world trading system. While the General Agreement on Tariffs and Trade (GATT) helped orchestrate the substantial reduction in tariffs after World War II, the multilateral approach to trade liberalisation has encountered difficulty in stemming the proliferation of non-tariff trade barriers and in extendin...
