The Relative Volatility of Commodity Prices

This paper studies the volatility of commodity prices on the basis of a large dataset of monthly prices observed in international trade data from the United States over the period 2002 to 2011. The conventional wisdom in academia and policy circles is that primary commodity prices are more volatile than those of manufactured products, even though most of the existing evidence does not actually attempt to measure the volatility of prices of individual goods or commodities. Rather the literature tends to focus on trends in the evolution and volatility of ratios of price indexes composed of multiple commodities and products. This approach can be misleading. Indeed, the evidence presented in this paper suggests that on average prices of individual primary commodities may be less volatile than those of individual manufactured goods.

Prisoner of the State

Premier Zhao Ziyang reveals the secret workings of China's government behind the Tiananmen massacre—and why he was deposed for trying to stop it. Prisoner of the State is the story of Premier Zhao Ziyang, the man who brought liberal change to China and who was dethroned at the height of the Tiananmen Square protests in 1989 for trying to stop the massacre. Zhao spent the last years of his life under house arrest. An occasional detail about his life would slip out, but scholars and citizens lamented that Zhao never had his final say. But Zhao did produce a memoir, secretly recording on audio tapes the real story of what happened during modern China’s most critical moments. He provides int...

Prisoner of the State

Prisoner of the State is the story of the man who brought liberal change to China and who, at the height of the Tiananmen Square protests in 1989, tried to stop the massacre and was dethroned for his efforts. When China's army moved in, killing hundreds of students and other demonstrators, Zhao was placed under house arrest at his home in Beijing. The Premier spent the last 16 years of his life, up until his death in 2005, in seclusion. China scholars often lamented that Zhao never had his final say. As it turns out, Zhao did produce a memoir, in complete secrecy. He methodically recorded his thoughts and recollections on what had happened behind the scenes during many of modern China's most critical moments. The tapes he produced were smuggled out of the country and form the basis for Prisoner of the State. Although Zhao now speaks from beyond the grave, his voice has the moral power to make China sit up and listen.

Data-Driven Evolutionary Optimization

Intended for researchers and practitioners alike, this book covers carefully selected yet broad topics in optimization, machine learning, and metaheuristics. Written by world-leading academic researchers who are extremely experienced in industrial applications, this self-contained book is the first of its kind that provides comprehensive background knowledge, particularly practical guidelines, and state-of-the-art techniques. New algorithms are carefully explained, further elaborated with pseudocode or flowcharts, and full working source code is made freely available. This is followed by a presentation of a variety of data-driven single- and multi-objective optimization algorithms that seamlessly integrate modern machine learning such as deep learning and transfer learning with evolutionary and swarm optimization algorithms. Applications of data-driven optimization ranging from aerodynamic design, optimization of industrial processes, to deep neural architecture search are included.

Advances in Efficiency and Productivity Analysis

The volume examines the state-of-the-art of productivity and efficiency analysis. It brings together a selection of the best papers from the 10th North American Productivity Workshop. By analyzing world-wide perspectives on challenges that local economies and institutions may face when changes in productivity are observed, readers can quickly assess the impact of productivity measurement, productivity growth, dynamics of productivity change, measures of labor productivity, measures of technical efficiency in different sectors, frontier analysis, measures of performance, industry instability and spillover effects. The contributions in this volume focus on the theory and application of economics, econometrics, statistics, management science and operational research related to problems in the areas of productivity and efficiency measurement. Popular techniques and methodologies including stochastic frontier analysis and data envelopment analysis are represented. Chapters also cover broader issues related to measuring, understanding, incentivizing and improving the productivity and performance of firms, public services, and industries.

Alternative Economic Indicators

Policymakers and business practitioners are eager to gain access to reliable information on the state of the economy for timely decision making. More so now than ever. Traditional economic indicators have been criticized for delayed reporting, out-of-date methodology, and neglecting some aspects of the economy. Recent advances in economic theory, econometrics, and information technology have fueled research in building broader, more accurate, and higher-frequency economic indicators. This volume contains contributions from a group of prominent economists who address alternative economic indicators, including indicators in the financial market, indicators for business cycles, and indicators of economic uncertainty.

Advances in Efficiency and Productivity II

This book surveys the state-of-the-art in efficiency and productivity analysis, examining advances in the analytical foundations and empirical applications. The analytical techniques developed in this book for efficiency provide alternative ways of defining optimum outcome sets, typically as a (technical) production frontier or as an (economic) cost, revenue or profit frontier, and alternative ways of measuring efficiency relative to an appropriate frontier. Simultaneously, the analytical techniques developed for efficiency analysis extend directly to productivity analysis, thereby providing alternative methods for estimating productivity levels, and productivity change through time or produ...
