Stylized Facts Of Nominal Exchange Rate Returns, Casper G. De Vries, K. U. Leuven Jan 1994

Stylized Facts Of Nominal Exchange Rate Returns, Casper G. De Vries, K. U. Leuven

Purdue CIBER Working Papers

This survey collects the stylized facts on nominal foreign exchange rate returns. The most salient statistical regularities: unit roots, fat tails, and volatility clusters are extensively discussed.


Diversification Responses To Environmental Uncertainties, Kent D. Miller Jan 1994

Diversification Responses To Environmental Uncertainties, Kent D. Miller

Purdue CIBER Working Papers

This study develops and tests a behavioral model of diversification responses to environmental uncertainties. Regression results using an international data set provide strong support for the general proposition that uncertainties associated with different environmental components--political, government policy, macroeconomic, competitive, input, and product demand uncertainties--have different implications for firm product and international market diversification.


A Model For Filter-Rule Gains In Foreign Exchange Markets, John Carlson, Marc Surchat Jan 1994

A Model For Filter-Rule Gains In Foreign Exchange Markets, John Carlson, Marc Surchat

Purdue CIBER Working Papers

An f-percent filter rule in a foreign exchange market calls for buying a foreign currency when its price has risen by f percent above a trough and holding until its price has fallen f percent from a peak. If the foreign exchange rate following a random walk, this is an unprofitable strategy. Since ex post filter rules continue to show positive gains on average, there must be a pattern in the data that makes these gains possible. Slight first-order autocorrelation, evident in the changes in actual exchange rates, is not strong enough by itself to account for the ex post …


The Influence Of Changing Trade Patterns Of Displacements Of Labor, Jon D. Haveman Jan 1994

The Influence Of Changing Trade Patterns Of Displacements Of Labor, Jon D. Haveman

Purdue CIBER Working Papers

While there is an extensive literature detailing the change in industrial employment resulting from changes int rading patterns, there is no significant literature that translates these changes in labor demand to actual worker hardship. This study provides evidence of the labor market effects of changes in import and export competition throughout the 1980's by focusing on the level of industry displacements, workers involuntarily separated from their industry of employment, rather than changes in the level of industry employment. The results therefore shed light on the number of workers that were measureably injured by changing trade patterns. The analysis is based …


Operational Flexibility Responses To Environmental Uncertainties, Kent D. Miller Jan 1994

Operational Flexibility Responses To Environmental Uncertainties, Kent D. Miller

Purdue CIBER Working Papers

This study develops and tests a behavioral model of organizational changes in operational flexibility. Regression results using an international data set provide strong support for the general proposition that uncertainties associated with different environmental components--poitical, government policy, macroeconomic, competitive, input and product demand uncertainties--have different implications for firm internal, locational, and supploer flexibility. Slack acts as a buffer attenuating, and often offsetting, the direct effects of uncertainties on changes in operational flexibility.


Classification Of Multi-Spectral Data By Joint Supervised-Unsupervised Learning, Behzad Shahshahani, David Landgrebe Jan 1994

Classification Of Multi-Spectral Data By Joint Supervised-Unsupervised Learning, Behzad Shahshahani, David Landgrebe

Department of Electrical and Computer Engineering Technical Reports

An important problem in pattern recognition is the effect of small design sample size on classification performance. When the ratio of the number of training samples to the number of feature measurements is small, the estimates of the discrimiriant functions are not accurate and therefore the classification results might not be satisfactory. This problem is becoming more and more important in remote sensing, as the number of available spectral bands is becoming greater and greater. In order to utilize fully the information contained in the high dimensional data, training samples are needed from all of the classes of interest. A …

Panglobal Distribution Of A Single Clonal Lineage Of The Irish Potato Famine Fungus, Stephen B. Goodwin, Barak A. Cohen, William E. Fry Jan 1994

Panglobal Distribution Of A Single Clonal Lineage Of The Irish Potato Famine Fungus, Stephen B. Goodwin, Barak A. Cohen, William E. Fry

Department of Botany and Plant Pathology Faculty Publications

More than 300 isolates of the Irish potato famine fungus, Phytopkthora iufesns, colc In 20 countries on five ontits, were analyzed for genetic variation at the mating type and two allozyme loci. A subset of more than 200 islates was also analyzed for DNA "fingerpint" variation. A surprisng result was that a single conal ineage dominated most populaton worldwide. AD of the variation within this loneage appeared to have arisen by mitotic embinat or by mutation. In addItion to the most common cal lineage, a number of diferent, but a rtiy closely related, lineages occurred in the United States and …
