Cross-hedging foreign currency risk: Empirical evidence from an error correction model

In this article, the traditional price change hedge ratio estimation method is extended by applying the theory of cointegration in the case of cross-hedging of spot exchange risk of the Belgian franc (BF), the Italian lira (IL), and the Dutch guilder (NG) with U.S. Dollar Index futures contracts. Previous studies ignore the last period's equilibrium error and short-run deviations. The findings of this study indicate that the hedge ratio estimated by the error correction method is superior to that obtained from the traditional method, as evidenced by the likelihood ratio test and out-of-sample forecasts. Hedgers will be able to control the risk of their portfolios more effectively at a lower cost.

A Time to Scatter Stones,and a Time to Gather Them: The Annual Cycle in Hedge Fund Risk Taking

Analyzing a sample of hedge fund daily returns from Bloomberg, we find a seasonal pattern in their risk taking. During earlier months of a year, poorly performing funds reduce risk. The reduction is stronger for funds with higher management fees, shorter redemption periods, and recently deteriorating performance, consistent with a managerial aversion to early fund liquidation. Toward the end of a year, poorly performing funds gamble for resurrection by increasing risk. It is largely achieved by increasing exposure to market factors, and can be linked to stronger indirect managerial incentives during the second half of a year.     

Experiencing meaningfulness climate in teams: How spiritual leadership enhances team effectiveness when facing uncertain tasks

This study integrates social information processing theory with leadership and climate literature, and aims to produce novel theoretical insights into whether and how spiritual leadership and task uncertainty foster conditions to enhance meaningfulness climate and subsequent team effectiveness in China. Team effectiveness was operationalized as team performance and team organizational citizenship behavior (OCB). Based on data collected at three time points over 12 months from multiple sources of 123 teams in China, we found that spiritual leadership was positively related to team performance and team OCB through meaningfulness climate. Further, the relationship between spiritual leadership and meaningfulness climate was stronger for teams with high task uncertainty than teams with low task uncertainty.

Going for gold: Investigating the (non)sense of increased advertising around major sports events

Major sports events draw unsurpassed media attention. Companies are motivated to increase their advertising investments around these events to reach large audiences in a short period. Is such an advertising surge actually beneficial though, or should companies avoid advertising in these periods because of negative effects of competitive interference? This study investigates when consumer packaged goods companies should invest in advertising to increase sales: before, during, or after the event or outside these event periods. The author estimates short- and long-term own- and cross-advertising elasticities for 206 brands using four years of weekly data. Although considerable heterogeneity exists across brands, own-advertising effectiveness diminishes especially before and during major sports events, in both the short and the long run. In addition, brands benefit less from category-demand effects through competitors' advertising. Conversely, greater increases in advertising spending resulting in significant growth in share of voice around focused, single-sport events are a successful strategy to overcome this overall general negative trend.     

Corruption: what are the effects on government effectiveness? Empirical evidence considering developed and developing countries

This study analyses the impact of corruption on government effectiveness for a sample of 130 countries. The findings suggest that less-corrupt countries have better quality of public service, better quality in the formulation and adoption of policies and greater credibility and government's commitment to such policies. The findings also suggest that the effect of corruption on government effectiveness is higher in developed countries. Moreover, the estimates also reveal that countries with the most indebted governments and with higher inflation rates have less-efficient governments, and an increase in rule of law represents a good strategy to improve government effectiveness. In turn, regarding developing countries, the findings show that countries with more democratic regimes have a higher degree of government effectiveness.     

Is Current Way of Promoting Sustainability,Sustainable?

Consumer behavior regarding sustainable products has been a complex concept. There is a discrepancy between consumer’s espoused concern towards environment and their purchase of environment friendly products. Past literature suggests greenwashing being a possible reason for this discrepancy. With greenwashing being caused by mismatch between communication and perceived performance, this article focuses on assessment of simultaneous impact of both communication and performance elements on brand attitude. A quantitative study was undertaken to test the hypotheses. This was followed by a qualitative study to understand alternative explanation of hypotheses that was not accepted. The research revealed that a consumer’s attitude toward a green brand is impacted both by his or her general skepticism towards green ads and the credibility that she assigns to the firm’s green message. Perceived value of product also had a positive impact on brand attitude. Findings advance academic literature and support managerial community by highlighting factors for building a positive green brand attitude and resultantly avoiding the trap of being equated with greenwashing.
