Expected market returns: SVIX,realized volatility,and the role of dividends

This note provides a replication of Martin's (Quarterly Journal of Economics, 2017, 132(1), 367–433) finding that the implied volatility measure SVIX predicts US stock market returns up to 12‐month horizons. I find that this result holds for both S&P 500 and CRSP market returns, regardless of whether returns include or exclude dividends. The predictability largely disappears after the SVIX index is replaced by an exponentially weighted moving average measure of realized volatility, suggesting that SVIX holds incremental forward‐looking information compared to realized volatility, despite the high correlation between the two volatility measures.     

GMM Estimation with Non‐causal Instruments under Rational Expectations*

Lanne and Saikkonen [Oxford Bulletin of Economics and Statistics (2011a) Vol. 73, pp. 581–592], show that the generalized method of moments (GMM) estimator is inconsistent, when the instruments are lags of variables that admit a non‐causal autoregressive representation. This article argues that this inconsistency depends on distributional assumptions, that do not always hold. In particular under rational expectations, the GMM estimator is found to be consistent. This result is derived in a linear context and illustrated by simulation of a nonlinear asset pricing model.     

The effects of a gamified human resource management system on job satisfaction and engagement

The pressures associated with the speed of competition, including the digitalization of workspaces, are increasing the need for modern organizations to drive employee satisfaction and engagement. Integrating gamification into the workplace has been identified as a possible strategy to promote employee participation, engagement and loyalty. Gamification is defined as the application of game design elements in a non‐game context, which, in this case, is the workplace. This article presents a 12‐month longitudinal study designed to investigate the role of gamification in fostering job satisfaction and engagement. The findings from a sample of 398 employees, including both treatment and control groups from a large multinational company that introduced a gamified human resource management (HRM) system, revealed the effects of certain gamification experiential outcomes related to driving employee satisfaction and engagement at work. Overall, our study highlights the possibilities of employing gamified HRM systems to influence employee attitudes and behavior at work.     

E-book pricing and vertical restraints

This paper empirically analyzes how the use of vertical price restraints has impacted retail prices in the market for e-books. In 2010, five of the six largest publishers simultaneously adopted the agency model of book sales, allowing them to directly set retail prices. This led the Department of Justice to file suit against the publishers in 2012, the settlement of which prevents the publishers from interfering with retailers’ ability to set e-book prices. Using a unique dataset of daily e-book prices for a large sample of books across major online retailers, we exploit cross-publisher variation in the timing of the return to the wholesale model to estimate its effect on retail prices. We find that e-book prices for titles that were previously sold using the agency model decreased by 18 percent at Amazon and 8 percent at Barnes & Noble. Our results are robust to different specifications, placebo tests, and synthetic control groups. Our findings illustrate a case where upstream firms prefer to set higher retail prices than retailers and help to clarify conflicting theoretical predictions on agency versus wholesale models.     

SEMI‐NONPARAMETRIC ESTIMATION OF CONSUMER SEARCH COSTS

This paper studies the estimation of the distribution of non‐sequential search costs. We show that the search cost distribution is identified by combining data from multiple markets with common search technology but varying consumer valuations, firms' costs, and numbers of competitors. To exploit such data optimally, we provide a new method based on semi‐nonparametric estimation. We apply our method to a dataset of online prices for memory chips and find that the search cost density is essentially bimodal, such that a large fraction of consumers searches very little, whereas a smaller fraction searches a relatively large number of stores.

MULTILATERAL INDICES: CONFLICTING APPROACHES?

This short paper focusses on an apparent conflict between two results from different approaches to the problem of finding multilateral index numbers. The impossibility theorem of Van Veelen (2002 ) is an axiomatic result that rules out the existence of a multilateral index that satisfies four modest requirements. This also implies that no bilateral index can consistently be generalized to a multilateral setting. Adopting a revealed preference approach, Dowrick and Quiggin (1997 ) however construct a multilateral extention of Fisher's ideal index, which preserves a range of desirable properties. This note shows what it is that drives the divergence between those two results. It also gives implications for practical use of results from either approach.     

Age‐related differences in the relations between individualised HRM and organisational performance: a large‐scale employer survey

The current study aimed to investigate the relationship between individualised HRM practices and several measures of organisational performance, including the moderating role of employee age in these relationships. A large‐scale representative study among 4,591 organisations in the Netherlands showed support for the relationships between individualised HR practices with organisational performance. Employee age moderated the relationships between the use of individualised practices and sickness absence and turnover, such that organisations with a high percentage of older workers benefited from work schedule practices, and organisations with high percentage of younger workers benefited from development practices.     

Competition and educational quality: evidence from the Netherlands

Little evidence is available for the effect of competition on educational quality as only a few countries allow large-scale competition. In the Netherlands, free parental choice has been present since the beginning of the twentieth century and can be characterized as a full voucher program with 100 % funding. Based on micro panel data for the Netherlands, we show that there is a relation between competition and educational outcomes in secondary education, but that it is often negative and small, sometimes insignificant but never positive. This effect is larger for small and medium-sized schools and for schools that do not have a Protestant or Catholic denomination.     

The Moderating Role of Tangibility in Synchronous Innovation in Services

A synchronous pattern of innovation as between technological and management innovation, for example, can help firms improve their performance. This article explores this idea with respect to servitizing companies that introduce service delivery innovation as a means of gaining competitive advantage. It finds that the degree of tangibility, an indicator of the firm’s position on the product–service continuum, affects whether and how managers recognize the need for management innovation when introducing service delivery innovation. Using a socio‐technical perspective in conjunction with insights from managerial cognition, the relationship between management innovation and two central types of service delivery innovation—technological and customer interface—is examined. Tangibility shapes the managerial cognitive structures that are related to the enterprise’s technical and social subsystems in a paradigm that is capable of demonstrating contrasting effects. Technological delivery innovation is related to management innovation in firms with high tangibility. Customer interface delivery innovation, on the other hand, relates to management innovation in firms with low tangibility. This study uses a sample of diverse firms with varying degrees of tangibility to provide support for this theory.     

Genome-wide association studies in economics and entrepreneurship research: promises and limitations

The recently developed genome-wide association study (GWAS) design enables the identification of genes specifically associated with economic outcomes such as occupational and other choices. This is a promising new approach for economics research which we aim to apply to the choice for entrepreneurship. However, due to multiple testing issues, very large sample sizes are needed to differentiate between true and false positives. For a GWAS on entrepreneurship, we expect that a sample size of at least 30,000 observations is required.
