Abstract

Purpose

Research has focused primarily on the antecedents that influence the risk taking of CEOs themselves. This study examines how an important event experienced by a CEO at a direct rival firm influences a CEO's risk-taking. It also examines how prior firm performance relative to aspirations moderates the relationship.

Design/methodology/approach

In order to test the hypothesis, the authors perform an a difference-in-differences methodology.

Findings

Using a difference-in-differences methodology, we find that when a CEO wins a prestigious CEO award, competitor CEOs increase their firm risk-taking in the post-award period. The proclivity becomes stronger when their prior firm performance relative to aspirations is better. These findings suggest that a CEO winning a prominent CEO award influences competitor CEOs' risk-taking.

Originality/value

This study contributes to the literature on managerial risk-taking by highlighting that a star CEO winning a prominent award may serve as a striving aspiration and induce competitor CEOs to take risks, and that two different types of aspirations – striving and competitive aspirations – interact to influence the competitor CEOs' risk-taking.

Abstract

Purpose

This paper aims to examine the effects of economic policy uncertainty (EPU) on accounting conservatism in Korean firms. An increase in EPU could widen information asymmetry between insiders and outsiders, to the detriment of a firm’s investment decisions, stock price and cost of capital. This paper hypothesizes that Korean firms are likely to decrease accounting conservatism during high EPU due to inefficient institutional structure and weak corporate governance, together with the vulnerability of the Korean economy to exogenous shocks.

Design/methodology/approach

This study measures a firm’s level of conservatism using three accrual-based models proposed by Ball and Shivakumar (2006): 1) the cash flow model (CF model), 2) the Dechow and Dichev model (DD model) and 3) the Jones model. As a robustness test, this paper uses C-score model as an alternative measure of accounting conservatism. The data set used in this study is a total of 23,109 firm-year observations during the sample period from 2000 to 2018.

Findings

The test results show that an increase in EPU adversely affects Korean firms’ accounting conservatism, and that this adverse impact is more pronounced in financially distressed and non-manufacturing firms. This study’s findings highlight the importance of institutional structure during a period of high EPU, which can create incentives for either improving or deteriorating reporting quality.

Originality/value

This study adds new evidence to extant literature on the effects of EPU on managers’ choice of accounting policies and demonstrates that managers in emerging markets may have different incentives to cope with country-specific EPU fluctuations.

Abstract

Purpose

Gut microbial changes are associated with diseases such as obesity and type 2 diabetes and may be influenced by diet patterns. Thus, this paper aims to investigate the effects of alcohol, sodium chloride (NaCl) and dietary restriction on the composition of the gut microflora.

Design/methodology/approach

Five-week-old male C57BL/6N mice were orally administered by gavage with ethanol (ET; 4 g/kg), 200 µL of 6% NaCl (NC), or equivalent volumes of phosphate-buffered saline (ET-control and NC-control) every two days for 10 weeks. The mice were also orally administered by gavage with the recommended diet (RD-control; 3 g per mouse per day), or with 40% (RD-40) or 60% restricted level (RD-60). DNA samples obtained from mice ceca were sequenced using the Illumina MiSeq Sequencing system; raw data were analyzed using BIOiPLUG software.

Findings

This study shows that high ethanol and NaCl consumption, and diet restriction can change the composition of the intestinal microflora, especially Akkermansia muciniphila in ET (p = 0.0050) and NT (p = 0.0366) groups. In addition, the ratio of Bacteriodetes/Firmicutes and the diversity of microflora were generally reduced (p = 0.0487-0.4929).

Originality/value

These results raise the possibility of a relationship between diet patterns, change of intestinal microbiome and disease, which must be further evaluated.

Abstract

Purpose

The purpose of this study was to explore the moderating role of communication in the relationship between person-organization fit (P-O fit) of openness to change, learning organization and knowledge sharing.

Design/methodology/approach

A total of 1,015 faculty and staff participants from three private universities in South Korea was included in the analysis. Individual and organizational aspects of openness to change were examined based on the P-O fit theory. Moderated polynomial regression and response surface methodology were used for data analysis.

Findings

At a higher level of communication, the congruence of openness to change between the individual and organization showed a positive fit effect on learning organization. The incongruence of openness to change between individual and organization, in which the organizations’ openness to change was higher than that of individuals, decreased the level of knowledge sharing when the level of communication was higher.

Originality/value

The results of this study support the theory and practice that consideration of P-O fit on openness to change and a strategic approach of communication are needed to succeed in organizational change.

Abstract

Purpose

Pricing studies have largely focused on sellers' pricing strategies and price determinants. To expand earlier work on sellers' pricing decisions, this study considers time as a major factor driving sellers' ticket prices in the secondary market. Specifically, because most secondary market transactions occur in the last moments before a game, this study considers how resellers adjust ticket prices within a few days prior to a game day including an actual game day.

Design/methodology/approach

To examine the impact of time on secondary market ticket prices for Major League Baseball (MLB), ticket prices were collected from StubHub (one of the largest secondary ticket markets) four times per game: from 3 days to 1 day prior to a game day and on the actual game day. Additionally, 10 control variables were obtained from previous research on price determinants (N = 19,155). A multiple regression model was created based on the extant literature regarding secondary market ticket prices.

Findings

Results indicate the number of days before a game negatively influenced ticket prices: resellers decreased ticket prices consistently during the last few days prior to a game's first inning. Specifically, secondary market ticket prices decreased relatively dramatically on an actual game day. Time had no significant effects on ticket prices 2 days prior to a game day. In addition to the role of time, league affiliation and the number of all-star players were identified as key price determinants in the secondary market. Moreover, changes in weather forecasts and the home team starting pitcher's ERA played significant roles in price changes.

Research limitations/implications

Despite containing a relatively high number of data observations compared with prior pricing studies, this study's findings were limited to certain teams. Additionally, as only MLB secondary market ticket pricing was considered, different outcomes and implications may apply in other major sport ticket markets (e.g. NBA, NFL, NHL and MLS) featuring distinct league structures, policies and demand.

Practical implications

This study offers practical guidance for sellers' pricing decisions. Most secondary ticket market sellers lowered their ticket prices relatively dramatically on an actual game day. Reducing ticket prices prior to a game day can lead to greater chances to avoid unsold tickets that compromise revenue management. This study's results also afford professional sport organizations and secondary ticket market consumers a clearer understanding of the factors resellers consider when setting ticket prices.

Originality/value

Although previous studies have uncovered essential elements influencing ticket prices and consumer demand in the secondary ticket market, little work has examined how time affects sellers' pricing decisions within a few days prior to a game day. Little is known about the elements that significantly influence sellers’ decisions to adjust (i.e. increase or decrease) ticket prices in the secondary market as well. This topic deserves ongoing attention, as new outcomes can supplement previous studies' findings due to changing market environments.

Abstract

Purpose

This study aims to examine how the partnership between StubHub and MLB affected consumers' perceptions of StubHub. The case of StubHub and MLB was selected based on their partnership history and the reputation of StubHub.

Design/methodology/approach

A Qualtrics survey panel was used to collect the survey data. Structural equation modeling was used to analyze the relationships between sponsor congruence, brand equity and purchase intention.

Findings

Sponsor congruence plays a significant role in consumers' perceived quality of StubHub. Additionally, brand equity significantly influenced purchase intention. More specifically, brand loyalty was the strongest indicator of intent to purchase tickets from StubHub. Brand loyalty and perceived quality indirectly affected the relationship between sponsor congruence and consumers' purchase intentions of StubHub.

Originality/value

Sponsor congruence between secondary ticket markets and sport leagues can provide a competitive advantage, helping create revenue generation and leverage for partnerships. Perceived quality can help facilitate this relationship and increase revenue generation.
