Heavy-Tailed Distributions and Robustness in Economics and Finance
This book focuses on general frameworks for modeling heavy-tailed distributions in economics, finance, econometrics, statistics, risk management and insurance. A central theme is that of (non-)robustness, i.e., the fact that the presence of heavy tails can either reinforce or reverse the implications of a number of models in these fields, depending on the degree of heavy-tailed ness. These results motivate the development and applications of robust inference approaches under heavy tails, heterogeneity and dependence in observations. Several recently developed robust inference approaches are discussed and illustrated, together with applications.
A Method of Calculating the Spectral Radius of a Nonnegative Matrix and Its Applications
We present a method of calculating the maximal eigenvalue of an indecomposable nonnegative matrix, which is based on ideas of geometric programming. In addition to that, we obtain estimates for elements of an indecomposable nonnegative matrix by its spectral radius. The results make it possible to obtain new necessary conditions for the productivity of the matrix of coefficients in the Leontief input-output model and have the immediate relation to the analysis of M-matrices. Another interesting application of the developed method is given by conditions of stability of the dynamic system of market equilibrium. Keywords and Phrases: Leontief model, Productiviy, Market equilibrium, Spectral radius, M-matrices, Geometric programming.
On the Religious Frontier
Modern Russia's turbulent relations with its Muslim frontiers date back centuries. Indeed the nineteenth century, when the Muslim Caucasus first came under Russian rule, witnessed many of the historical antecedents to today's violent confrontations. With this in mind, On The Religious Frontier examines the history of Muslim Azerbaijan under Christian Orthodox Russian imperial rule and the attempts of the Russian administrators of the Caucasus to integrate the region into the empire. Drawing on original archival research from across Azerbaijan and Russia, Firouzeh Mostashari considers the formation of a Russian colonial administration in the Muslim Caucasus; subsequent social, political and economic developments; and the local responses to conquest, military rule and Russification. From 1804 to the Bolshevik Revolution of 1917, On The Religious Frontier offers a fascinating and timely insight into both the period itself and the ways in which the seeds of recent conflict were sown in tsarist Russia. This is important reading for all scholars of the history and politics of the Caucasus, as well as those with an interest in imperial Russia and its relationship with minority groups.
The Kahans from Baku
The Kahans from Baku is the saga of a Russian Jewish family. Their story provides an insight into the history of Jews in the Imperial Russian economy, especially in the oil industry. The entrepreneur and family patriarch, Chaim Kahan, was a pious and enlightened man and a Zionist. His children followed in his footsteps in business as well as in politics, philanthropy, and love of books. The book takes us through their forced migration in times of war, revolution, and the twentieth century’s totalitarian regimes, telling the story of fortune and misfortune of one cohesive family over four generations through Russia, Germany, Denmark, and France, and finally on to Palestine and the United States of America.
Gulag Voices
In this volume, the powerful voices of Gulag survivors become accessible to English-speaking audiences for the first time through oral histories, rather than written memoirs. It brings together interviews with men and women, members of the working class and intelligentsia, people who live in the major cities and those from the "provinces," and from an array of corrective hard labor camps and prisons across the former Soviet Union. Its aims are threefold: 1) to give a sense of the range of the Gulag experience and its consequences for Russian society; 2) to make the Gulag relevant to English-speaking readers by offering comparisons to historical catastrophes they are likely to know more about, such as the Holocaust; and 3) to discuss issues of oral history and memory in the cultural context of Soviet and post-Soviet society.
Product Returns Management in Online Retail
In Chapter 1, I and coauthors study the problem of predicting the product return rate using the products' visual information. In online channels, products are returned at high rates. Shipping, processing, and refurbishing are so costly that a retailer's profit is extremely sensitive to return rates. Using a large dataset from a European apparel retailer, we observe that return rates for fashion items bought online range from 13% to 96%, with an average of 53% - many items are not profitable. Because fashion seasons are over before sufficient data on return rates are observed, retailers need to anticipate each item's return rate prior to launch. We use product images and traditional measures ...

Schools of Architecture
In this book you will find another manifestation of this sub-culture. It takes the form of a report on a competition entitled 'The school of architecture as a subject of design', in which architectural students were invited to design a school of architecture for the future. The organizer, the Netherlands Architecture Institute, received over 400 entries from all over the world, from China to Mexico, from Sweden to Australia. In addition to the space devoted to the winning designs, the book also provides a qualitative and quantitative overview of the entries. In analysing the variety of answers to the competition brief it offers a fascinating insight into the ambitions and dreams of a future generation of architects.
