Empirical Asset Pricing via Machine Learning
We perform a comparative analysis of machine learning methods for the canonical problem of empirical asset pricing: measuring asset risk premiums. We demonstrate large economic gains to investors using machine learning forecasts, in some cases doubling the performance of leading regression-based strategies from the literature. We identify the best-performing methods (trees and neural networks) and trace their predictive gains to allowing nonlinear predictor interactions missed by other methods. All methods agree on the same set of dominant predictive signals, a set that includes variations on momentum, liquidity, and volatility.

Antecedents and Consequences of Customer Satisfaction: Do They Differ Across Online and Offline Purchases?
[Display omitted]
•Customer satisfaction relationships differ in online and offline purchasing.•Perceived value is a stronger driver of satisfaction in online purchases.•Overall quality and expectations are stronger drivers of satisfaction offline.•Customers are more satisfaction-sensitive when purchasing online.•Differences generally persist across customer demographics and retail categories.
Retailers seek to utilize both online and offline purchase channels strategically to satisfy customers and thrive in the marketplace. Unfortunately, current multichannel research is deficient in answering what drives customers’ satisfaction, and consequently their loyalty, differently when customers purchase online versus at a physical store. This gap in knowledge can be a significant concern for retailers due to the negative impact of having dissatisfied customers on their bottom lines. Using a version of the American Customer Satisfaction Index (ACSI) model, we demonstrate several important purchase-channel differences in the antecedents of customer satisfaction and its subsequent effect on customer loyalty. Specifically, we show that when retail customers buy electronic goods online they view purchase value as a significant attribute in rating satisfaction, and are more satisfaction-sensitive when making repurchase decisions than when they purchase offline. On the other hand, the overall quality of the purchase experience and customer expectations are stronger drivers of customer satisfaction in the offline purchases. We provide evidence that these differences between the channels generally persist across customer demographics (gender, age, and education) and broader product categories, and we also discuss the specific contexts where they do not. Our work offers actionable guidance to retailers seeking to enhance customer satisfaction and loyalty across both the online and offline channels.

Handbook of research on comparative human resource management
This unique and path-breaking Handbook explores the issue of comparative human resource Management (HRM) and challenges the notion that there can be a 'one best way' to manage HRM. The Handbook of Research on Comparative Human Resource Management provides a theoretical, practical and regional analysis of comparative HRM. This book, edited by two specialists on comparative HRM and written by leading experts on each topic and from each region, explores the range of different approaches to conceptualizing HRM, and highlight HRM policy and practice that occur in the various regions of the world. As such, the volume provides a challenge to the typical assumption that there are consistent problems in managing human resources around the globe that call for standardized solutions. Instead, the contributors emphasize the importance of institutional and cultural factors that make HRM a most context-sensitive management task. Offering a comprehensive view for readers with different interests, this insightful Handbook will prove to be an essential resource for academics, researchers and postgraduate students in international business, business administration, HRM, socio-economics and cross-cultural management. Practitioners interested in the cultural aspects of HRM will also find this Handbook to be of invaluable interest.

Which Alpha?
A common approach to comparing asset pricing models involves a competition in pricing test-asset returns. In contrast, we show that for models with traded factors, when the comparison is framed appropriately in terms of success in pricing both the test-asset and factor returns, the extent to which each model is able to price the factors in the other model is what matters for model comparison. Test assets are irrelevant based on several prominent criteria. For models with nontraded factors, test assets are relevant for model comparison insofar as they are needed to identify factor-mimicking portfolio returns.

EXCHANGE ARRANGEMENTS ENTERING THE TWENTY-FIRST CENTURY
This article provides a comprehensive history of anchor or reference currencies, exchange rate arrangements, and a new measure of foreign exchange restrictions for 194 countries and territories over 1946–2016. We find that the often cited post–Bretton Woods transition from fixed to flexible arrangements is overstated; regimes with limited flexibility remain in the majority. Even if central bankers’ communications jargon has evolved considerably in recent decades, it is apparent that many still place a large implicit weight on the exchange rate. The U.S. dollar scores as the world’s dominant anchor currency by a very large margin. By some metrics, its use is far wider today than 70 years ago. In contrast, the global role of the euro appears to have stalled. We argue that in addition to the usual safe assets story, the record accumulation of reserves since 2002 may also have to do with many countries’ desire to stabilize exchange rates in an environment of markedly reduced exchange rate restrictions or, more broadly, capital controls: an important amendment to the conventional portrayal of the macroeconomic trilemma.

Responding to globalization
\"The new challenges and opportunities created by the spread of globalization have reshaped both institutional and individual responses to this phenomenon. This comprehensive analysis of the way in which governments and firms have responded to globalization examines closely the options available to both, and the historical and institutional contexts to the strategic decisions made.\" \"This rigorous survey focuses on political, ideational and economic factors lying behind these responses to globalization. It is essential reading for all those interested in globalization, international business and international political economy.\"--Jacket.

RCTS TO SCALE
Nudge interventions have quickly expanded from academic studies to larger implementation in so-called Nudge Units in governments. This provides an opportunity to compare interventions in research studies, versus at scale. We assemble a unique data set of 126 RCTs covering 23 million individuals, including all trials run by two of the largest Nudge Units in the United States. We compare these trials to a sample of nudge trials in academic journals from two recent meta-analyses. In the Academic Journals papers, the average impact of a nudge is very large—an 8.7 percentage point take-up effect, which is a 33.4% increase over the average control. In the Nudge Units sample, the average impact is still sizable and highly statistically significant, but smaller at 1.4 percentage points, an 8.0% increase. We document three dimensions which can account for the difference between these two estimates: (i) statistical power of the trials; (ii) characteristics of the interventions, such as topic area and behavioral channel; and (iii) selective publication. A meta-analysis model incorporating these dimensions indicates that selective publication in the Academic Journals sample, exacerbated by low statistical power, explains about 70 percent of the difference in effect sizes between the two samples. Different nudge characteristics account for most of the residual difference.
