The analysis reveals that sterilization is an important element of the response to shocks to foreign assets in both economies. In particular, monetary authorities do not appear to be prepared to accept fluctuations in the exchange rate and the money supply that may result from changes in foreign assets, but more readily accept fluctuations in these variables that result from domestic credit shocks. There are also differences in the responses of Korea and Taiwan that suggest that the former may be more insulated from external shocks.

Contemporary philosophical discussions again raise this issue by emphasizing the epistemological influence of technological means in scientific research. The technological procedures upon which theoretical physics and cosmology depend give rise to charges of reductionism or epistemological naivete. According to such arguments, science rests on a technological reduction that leads in practice to a peculiar “construction” of scientific objects. As a consequence, questions are raised about the true limits of scientific objectivity and the general validity of science.

We define crises on a country by country basis using a new criterion that takes into account variations in the volatility of exchange rates over time and across countries. Using a Poisson regression model, we find that over the post-Bretton woods period, a small number of common external shocks can explain between sixty to eighty percent of the variation in the total number of crises over time, depending upon the set of countries one looks at. Our findings provide one explanation of why currency crises sometimes bunch together and sometimes do not.

This representation allows the definition of a chromatic distance. Using this distance we define a fuzzy gradient with good properties of perceptual color constancy. In this paper we present a watershed based image segmentation method using using this fuzzy gradient. Oversegmentation is corrected applying a region merging strategy based on the chromatic distance defined on the spherical coordinate representation.

Larger budget deficits and growth in central bank domestic credit appear to be associated with episodes of depreciation rather than episodes of appreciation or periods of tranquility, indicating that unusually expansionary or contractionary policies may contribute to speculative pressures in foreign exchange markets. There also is some evidence that episodes of speculative pressure may arise when economic conditions make it costly for the government to maintain a stable exchange rate.
