Economic Distance and Cross-Country Spillovers

Rates of long-run economic growth are not independent across countries. To account for this dependence we decompose the spatial covariance function of growth rates into a function of each countrys own observable characteristics, its unobservable characteristics, and cross-country spillovers. We use original data on economic distance to structure observed variation in countries long term growth rates. We use this structure to estimate the magnitude of economic interdependence among nations, and to give a nonparametric characterization of the relationship between economic distance and the magnitude of cross-country spillovers. These spillovers turn out to be quite important, accounting for more of the spatial covariance in growth rates than unobservable variables, and by some measures rivalling the importance of the countrys own observable characteristics.     

The Influence of B to B Social Media Message Features on Brand Engagement: A Fluency Perspective

Purpose: Social media is increasingly drawing the attention and interest of business-to-business (B to B) organizations. Yet, B to B organizations remain cautious in their social media pursuits, in part based on a stated lack of understanding for best practices. The purpose of the current work is to take initial steps to address this challenge by identifying specific social media message features that influence online users’ engagement with B to B organizations.

Methodology/Approach: This work examines the Twitter feeds of the top 50 social B to B brands (as reported by Brandwatch in 2015) to examine the effects of message features (hashtags, text difficulty, embedded media, and message timing) on user engagement, captured in terms of Twitter likes and retweets.

Findings: We argue that message features that enhance fluency (e.g., images) should enhance engagement. In contrast, those that disrupt fluency (e.g., hasthags) should result in lower levels of engagement. Consistent with these predictions, we find that hashtags and text difficulty correlate to lower levels of engagement whereas embedded media in the form of images and video correlate to higher levels of engagement. Also consistent with the proposed fluency framework, we find that tweets from B to B organizations generate greater engagement on evenings and weekends.

Research Implications: This research applies a fluency lens to identify specific message features that influence online engagement. In doing so, it highlights fluency as a powerful construct for understanding the drivers of B to B social media brand engagement. More generally, this work suggests fluency as a valuable conceptual lens for developing effective B to B social media strategies. This research also speaks to the complexity of B to B social media strategies – organizations must go beyond content and platform decisions, to also consider the specific features of the message.

Practical Implications: Social media is becoming more and more important to B to B organizations and is as yet an underutilized engagement tool. The current work offers initial strategies regarding message features that business practitioners can incorporate into their content development strategies to strengthen engagement. Specifically, efforts should be made to attain high levels of fluency in B to B social media content development.

Originality/Value/Contribution of the Paper: The current work offers initial insights as to the importance of understanding not only how social media topics/content influence engagement, but also the influence of message features (e.g., hashtags, embedded media). In doing so, it highlights fluency as a novel conceptual lens for developing more effective B to B social media strategies. Finally, it draws on actual tweets from leading B to B brands to examine the proposed influence of message features on engagement.     

Commonalities in investment strategy and the determinants of performance in mutual fund mergers

This paper examines the determinants of cross-sectional variation in post-merger mutual fund performance. Mergers between funds with similar management objectives, as reflected by average portfolio book-to-market ratio, price–earnings ratio, beta and market capitalization values, outperform mergers between funds with dissimilar strategies. This superior performance transcends lower portfolio rebalancing costs which might be realized between merging funds which hold more assets in common. These results suggest that mutual fund mergers create collaborative benefits between funds with similar strategies. We also examine if fund governance structures influence the fund pairing process, testing if stronger fund oversight mitigates pairing mismatches. We find that less independent boards of trustees and boards with higher compensation are related to greater strategic mismatches between funds. These results suggest that more entrenched boards are more tolerant of fund mismatches which benefit the investment company, yet are not in investor’s best interests.     

Agricultural Markets as Relative Performance Evaluation

Relative performance schemes such as tournaments are commonly used in markets for a variety of livestock and processing commodities, while explicit versions of these schemes are rarely used in markets for fresh fruits and vegetables and specialty grains. We show how contracts for these latter commodities do in fact provide relative performance incentives, albeit indirectly, via a payment mechanism that depends on market prices. In such contracts, compensation is often an increasing function of revenue; this implements a relative performance scheme by making each grower's payment an increasing function of his own output but a decreasing function of other's output.     

I used to work at Goldman Sachs! How firms benefit from organizational status in the market for human capital

How does employer status benefit firms in the market for general human capital? On the one hand, high status employers are better able to attract workers, who value the signal of ability that employment at those firms provides. On the other hand, that same signal can help workers bid up wages and capture the value of employers' status. Exploring this tension, we argue that high status firms are able to hire higher ability workers than other firms, and do not need to pay them the full value of their ability early in the career, but must raise wages more rapidly than other firms as those workers accrue experience. We test our arguments using unique survey data on careers in investment banking. Copyright © 2014 John Wiley & Sons, Ltd.     

People and process,suits and innovators: the role of individuals in firm performance

Performance differences between firms are generally attributed to organizational factors rather than to differences among the individuals who make up firms. As a result, little is known about the part that individual firm members play in explaining the variance in performance among firms. This paper employs a multiple membership cross‐classified multilevel model to test the degree to which organizational or individual factors explain firm performance. The analysis also examines whether individual differences among middle managers or innovators best explain firm performance variation. The results indicate that variation among individuals matter far more in organizational performance than is generally assumed. Further, variation among middle managers has a particularly large impact on firm performance, much larger than that of those individuals who are assigned innovative roles.
