We introduce combinatorial types of arrangements of convex bodies, extending order types of point sets to arrangements of convex bodies, and study their realization spaces. Our main results witness a trade-off between the combinatorial complexity of the bodies and the topological complexity of their realization space. On one hand, we show that every combinatorial type can be realized by an arra...

Temzelides and Williamson present a model of private currency issuance to study the effect of clearing arrangements on the prices at which private currencies trade, on the volume of exchange, and on welfare. Their findings hinge on three factors: the location of the issuers relative to the area in which their currencies circulate, whether there is an arrangement for clearing nonlocally issued c...

In an investigation of approaches to compact relay lenses for special effect photography, the potential of microlenslet arrays in image formation is investigated. In this paper, various arrangements of microlenslet arrays and associated baffles are considered and their role on image quality presented. Findings through software simulations clearly demonstrate the trade-offs between image quality...

a r t i c l e i n f o The number of preferential trade agreements has greatly increased over the past two decades, yet most existing arrangements take the form of free trade areas, and less than 10% can be considered to be fully fledged customs unions. This paper develops a political economy model of trade policy under imperfect competition to provide a positive explanation for the prevalence o...

Buckley & Strange (2015) have highlighted the major changes in the global location of economic activity over the past 30 years, with the emerging economies assuming greater shares relative to the advanced economies. They noted that the major drivers of these changes included inter alia economic restructuring and market liberalization in many countries in Asia, Eastern Europe and elsewhere; fina...

The empirical literature offers regional integration arrangements reduce trade costs among partner countries this reduction in cost not only increase trade but also act as a stimulus to increase FDI flow. South Asian Association for Regional Cooperation (SAARC) was established in 8 December 1985 with the seven South Asian countries (Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri L...

I evaluate in this paper the impact of free trade areas (FTAs) on the world trading system. I use an oligopolistic-political-economy model where the external tariffs of FTA members, as well as the decision to form FTAs, are endogenously determined. In this context, I show that FTAs are primarily beneficial to the multilateral trading system. This conclusion is based, first, upon the finding tha...

Many housing and welfare researchers in the last few decades have dealt with the so-called trade-off debate concerning the trade-off between welfare and home ownership. Countries with a high home ownership rate have lower welfare arrangements. The debate is about the causality of this statistical relationship; is welfare low because the home ownership rate is high or is it the other way around....

The health care sector is among the most rapidly growing sectors in the world economy. It is estimated to generate US$ 3 trillion per year in countries in the Organisation for Economic Co-operation and Development alone and is expected to rise to US$ 4 trillion by 2005 (1, 2). The globalization of health services is reflected in the growing cross-border delivery of health services, through move...
