Virtual economic transactions have radically transformed the way we think about trade and markets in closed and open economies. Continuous decline in costs of information and communications and setting up of phenomenally large number of virtual platforms have brought in 'Time' as an essential element in the discourse on international trade. This work delves deep into the issue of how Time enters as a major catalyst of international trade and virtual transactions. This changes the way we look at ideas of comparative advantage, factor mobility, growth, income distribution, and allied concepts. A key result is that greater physical distance might encourage trade contrary to what we are accustomed to accept.

There is not enough water globally for all the things humans need and want water to do for us. Water supply bubbles are bursting in China, the Middle East and India with potentially serious implications for the global economy and for political stability. Even the United States is depleting groundwater on average 25% faster than it is being replenished. Our thirst for water grows with our population, but the amount of fresh water available on Earth is fixed. If we assume "business as usual" by 2050 about 40% of the projected global population of 9.4 billion is expected to be facing water stress or scarcity. With increasing climate variability being predicted by global climate models, we are likely also to have more people without adequate water more of the time, even in water-rich regions. Irrigation productivity rose dramatically over the past 40 years as a result of the Green Revolution. However, even if we disregard the environmental impacts caused by that revolution, we are no nearer to achieving global food security than we were 40 years ago, as every time we come close to filling the food production gap population growth and ecosystem decline associated with water diversions to human purposes set us back. Our natural and agricultural ecosystems are trying to tell us something. This book pursues these overarching themes connecting to water and food production at global and regional scales. The collection offers a comprehensive discussion of all relevant issues, and offers a wide-ranging discussion with the aim of contributing to the global debate about water and food crises.

Virtual worlds have exploded out of online game culture and now capture the attention of millions of ordinary people: husbands, wives, fathers, mothers, workers, retirees. Devoting dozens of hours each week to massively multiplayer virtual reality environments (like World of Warcraft and Second Life), these millions are the start of an exodus into the refuge of fantasy, where they experience life under a new social, political, and economic order built around fun. Given the choice between a fantasy world and the real world, how many of us would choose reality? Exodus to the Virtual World explains the growing migration into virtual reality, and how it will change the way we live--both in fantasy worlds and in the real one.

A collection of papers by some of the world's leading specialists on global value chains (GVCs). It examines how GVCs have evolved and the challenges they face in a rapidly changing world.
