''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""

Economic Theory and Mathematical Economics: Mathematics for Stability and Optimization of Economic Systems provides information pertinent to the stability aspects and optimization methods relevant to various economic systems. This book presents relevant mathematical theorems sufficient to develop important economic systems, including Leontief input–output systems, Keynesian dynamic models, the Ramsey optimal accumulation systems, and von Neumann expanding economic systems. Organized into two parts encompassing nine chapters, this book begins with an overview of useful theorems on matrices, eigenvalue problems, and matrices with dominant diagonals and P-matrices. This text then explores the linear transformations on vector spaces. Other chapters consider the Hawkins–Simon theorem concerning non-negative linear systems. This book discusses as well the dual linear relations and optimization methods applicable to inequality economic systems. The final chapter deals with powerful optimal control method for dynamical systems. This book is a valuable resource for mathematicians, economists, research workers, and graduate students.

Some central banks have maintained overvalued official exchange rates, while unable to ensure that supply of foreign exchange meets legitimate demand for current account transactions at that price. A parallel exchange rate market develops, in such circumstances; and when the spread between the official and parallel rates is both substantial and sustained, price levels in the economy typically reflect the parallel market exchange rate. “Recognizing reality” by allowing economic agents to use a market clearing rate benefits economic activity without necessarily leading to more inflation. But a unified, market-clearing exchange rate will not stabilize without a supportive fiscal and monetary context. A number of country case studies are included; my thanks to Jie Ren for pulling together all the data for the country case studies, and the production of the charts.

The paper reviews recent theoretical and empirical developments in the analysis of informal currency markets in developing countries. The basic characteristics of these markets are highlighted, and alternative analytical models to explain them are discussed. The implications for exchange rate policy —including imposition of foreign exchange restrictions, devaluation, and unification of exchange markets— in countries with a sizable parallel market are also examined.

This volume grew out of a National Bureau of Economic Research conference on exchange rates held in Bellagio, Italy, in 1982. In it, the world's most respected international monetary economists discuss three significant new views on the economics of exchange rates - Rudiger Dornbusch's overshooting model, Jacob Frenkel's and Michael Mussa's asset market variants, and Pentti Kouri's current account/portfolio approach. Their papers test these views with evidence from empirical studies and analyze a number of exchange rate policies in use today, including those of the European Monetary System.

Standing atop the wall of California, Michael Checchio decided to head out for Saline and Death Valley, the canyonlands of Arizona and Utah and the uplands of New Mexico. He would re-visit old haunts and explore new ones-and in so doing rediscover a world he thought he already knew. In Sundown Legends, Checchio offers up the American Southwest as a spiritual repository and source of inspiration. On his travels he talked to individuals whose imaginations have been shaped by the power of this desert landscape, including Ken Sleight, the Utah wilderness outfitter, who was the inspiration for a character in THE MONKEY WRENCH GANG and novlist John Nichols, author of the MILAGRO BEANFIELD WAR, who wandered into Taos in the late sixties and found a place to make his stand. Like Michael Wallis, Michael Checchio is a powerfully gifted writer who has created an intimate and lasting portrait of one of our last remaining wild places.
