Alternative payment instruments are studied in an economy with private information, delayed communication, and limited commitment. Attention is restricted to checks and bank drafts, which differ in resource cost and communication characteristics. Checks are less costly but settlement delays create a limited commitment constraint. We Þnd that drafts dominate at low wealths and checks at higher w...

The appropriate configuration of marine reserves for maximizing harvests or ensuring species persistence when there is uncertainty or variability in larval dispersal patterns is not completely understood. This is particularly true in environments with large alongshore advection rates, as the success of a system of marine reserves depends on connectivity through larval and/or adult dispersal bet...

The control of gastrointestinal nematodes relies at present mostly on antihelmintic treatments using synthetic molecules. This approach, however, has led to the appearance of resistance to some types of antihelmintics which, together with the need to cut down on the use of chemicals, has fostered the development of other control methods, such as biological control, which is the use of living or...

A common approach for building a drug delivery system is to incorporate the drug within the nanocarrier that results in increased solubility, metabolic stability, and improved circulation time. However, recent developments indicate that selection of polymer nanomaterials can implement more than only inert carrier functions by being biological response modifiers. One representative of such mater...

Zinc oxide (ZnO) nanoparticles have received growing attention for several biomedical applications. Nanoparticles proposed for these applications possess the potential to interact with biological components such as the blood, cells/ tissues following their administration into the body. Hence we carried out in vivo investigations in Swiss Albino Mice to understand the interaction of ZnO nanorods...

This paper attempts to provide an economic framework for assessing why and how Internet telephony may a ect the international accounting rate system in particular, and communication over circuit switched networks in general. It reviews the regulatory treatment of Internet telephony, and compares the costs and prices of making international calls over the Internet and the public switched telepho...

For the last half century, international trade has been an important contributor to the growth of the world economy. Similarly, over the past twenty years, after China’s decision to pursue a market opening policy, the growth of the Chinese economy has been led by the rapid growth of its exports and imports. However this growth in international trade has been accompanied by an increase in the nu...

We introduce contingency fees into the Reinganum and Wilde (1986) signaling model of litigation. The effect of contingency fees on settlement depends upon the details of the contingency fee contract and the nature of the informational asymmetry assumed in the model. Introducing bifurcated fee contracts where the contingency percentage is higher at trial changes the selection of disputes at tria...

This article, based on a lecture given at the inauguration ceremony for the new Advisory Centre on WTO Law, describes the broader world trading landscape into which this new Centre emerges. Taking into account the possible implications of the events on September 11, this article provides a brief analysis of the current trade policy climate, asserting the necessity of institutions for the succes...
