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...

One of the most striking development in the world trading system since the mid 1990s is a surge in Regional Trade Agreements (RTAs). From about 50 till 1990, the number of RTAs notified to the World Trade Organization (WTO) has crossed 250 in 2003 and estimates indicate that over 300 RTAs will be in effect by 2007. Initially WTO encouraged the growth of RTAs because it believed that regional in...

Donor_s demand equations for alternative forms of aid are derived for three allocation processes: noncooperative Nash-Cournot, cooperative Lindahl, and bureaucratic. Based on OECD data for official development assistance for 1970– 2001, we apply non-nested tests to distinguish between Nash-Cournot and Lindahl reduced-form equations for 15 major donor nations. Noncooperative Nash-Cournot behavio...

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 ...

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 ...
