Jupiter is an extraordinarily colourful and dynamic planet. Over minutes, one can watch tiny shadows cast by its moons slide over its surface; over days and weeks parades of diverse, giant swirling storms can be seen to move and evolve. It is because of this richness of visual and physical properties that Jupiter has intrigued amateur and professional astronomers and has been the goal of several space missions. This highly illustrated volume provides a comprehensive and accessible account of Jupiter and its satellites. It reviews systematic telescopic observations that have stretched over more than a hundred years, in addition to modern observations and theories, and the wealth of data from the Pioneer, Voyager and Ulysses space missions. As well as a thorough survey of the planet's atmosphere, this volume presents an up-to-date account of our present knowledge of Jupiter's satellites and magnetosphere, at a level accessible to the non-specialist. This volume provides the definitive account of Jupiter for advanced amateur astronomers, professional astronomers and planetary scientists.

We find evidence that the law of one price (LOOP) holds more nearly for country pairs that are within geographic regions than for country pairs that are not. These findings are established using consumer price data from 23 countries (including data from eight North American cities.) We find that failures of LOOP are closely related to nominal exchange rate variability, suggesting a link to sticky nominal prices. We also find that distance can explain failures of LOOP, suggesting the failures arise from imperfect market integration. However, these two sources do not explain all of the failures of LOOP. We speculate that integrated marketing and distribution systems within regions cause LOOP to hold more nearly intraregionally. We present a formal model of marketing and distribution to illustrate this hypothesis.

Using consumer price indexes from cities in the U.S., Canada and Mexico, we estimate the "border effect" on U.S.-Mexican relative prices and find that it is nearly an order of magnitude larger than for U.S.-Canadian prices. However, during a very stable sub-period in Mexico (May 1988 to November 1994), the "width" of the U.S.-Mexican border falls dramatically and becomes approximately equal to the U.S.-Canadian border. We then show that when consideration is limited to cities lying geographically very close to the U.S.-Mexican border--San Diego, Los Angeles, Houston, Dallas, Tijuana, Mexicali, Juarez, and Matamoros--the border width falls compared to that estimated with the full sample of U.S. and Mexican cities, but falls only very slightly. We also present evidence that the border effect in U.S.-Mexican prices is not primarily due to the border effect in U.S.-Mexican wages. Finally, using the prices of 276 highly dis-aggregated goods and services, we estimate the variability of relative prices of different items within Mexican cities. This measure of relative price variability declines during the stable peso sub-period, but by less than the decline in nominal and real (i.e., CPI-based) exchange rate variability. Our results are strong evidence of a "nominal border effect" in relative prices within NAFTA, but also indicate that real side influences are important.
