The effects of crowdsourcing contribution type and temporal consistency on new product development success

Extant literature suggests that individuals contribute to crowdsourcing programs in various ways but offers few insights about whether participants' creative contributions (original new product submissions) or their evaluative contributions (scoring or commenting on others' submissions) have a greater impact on their ability to create commercializable new products. Using a large-scale data set obtained from the crowdsourcing website Threadless.com, our study examines the relative impact of participants' creative and evaluative contributions and the effects of different types of evaluative contributions on submission success (i.e., a participant's ability to generate a commercializable new product). Our findings reveal that submission success is enhanced when participants generate both creative and evaluative contributions. In addition, we find that submission success depends not only on the volume of the creative contributions that a participant makes but also on the temporal consistency with which said contributions are made (i.e., adopting a consistent vs. a sporadic submission pattern). Specifically, our findings show that a participant's creative contribution consistency enhances their submission success, especially when creative contribution volume is high. This research extends the existing crowdsourcing literature by offering new insights about how contribution type and contribution consistency in a crowdsourcing program impact submission success.     

Price dispersion and optimal price categories with limited memory consumers

In this paper, we study consumers with limited memory and examine the effects of their price categorization on the pricing strategies of competing firms. The valuations of consumers are assumed to be heterogeneous. We find that it is possible to observe price dispersion even when each firm charges a single price if the consumers categorize prices non‐optimally. Moreover, we demonstrate that the likelihood of a price dispersion outcome is reduced when consumers with limited memory set up the price categories optimally. These findings suggest that the consumers' limited memory and their sub‐optimal behavior, that is, their inability to choose price categories optimally can be a reason for observed price dispersion.

The evolution of the monetary transmission channels in Turkey: evidence from a TVP-VAR model

This article investigates the evolution of the monetary transmission mechanisms in Turkey for the period from January 1986 to December 2016. To this aim, the impacts of monetary variables on the prices and economic activity are investigated with a time-varying vector autoregressive model based on. The evidences from the time-varying responses indicate that the adoption of inflation targeting policy has markedly affected the functioning of transmission channels. The results also suggest that local and global financial crises may magnify the impact of monetary policy shocks on the overall economy.     

When do the stock market returns to new product preannouncements predict product performance? Empirical evidence from the U.S. automotive industry

Substantial research has examined how stock market reactions to marketing actions affect subsequent marketing decisions. However, prior research provides limited insights into whether abnormal stock returns to a marketing action actually predict the future performance resulting from that action. This study focuses on new product preannouncements (NPPAs) and investigates the relationship between short-term stock market returns to an NPPA and the post-launch new product performance under various industry and firm conditions. Findings based on a dynamic panel data analysis of 208 NPPAs in the U.S. automotive industry between 2001 and 2014 reveal that stock returns associated with an NPPA are not an appropriate forward-looking measure of future product performance. However, under specific conditions (i.e., when the preannouncement is specific, the preannounced new product has low innovativeness, the preannouncing firm has a high reputation and invests heavily in advertising, and the preannouncement environment is less competitive), abnormal stock returns to NPPAs actually predict the future performance of new products. Thus, this study extends the marketing–finance and innovation literature with its focus on the conditions that affect the predictive power of immediate stock returns for the future performance of new products.

Corporate bond credit spreads and forecast dispersion

Recent research establishes a negative relation between stock returns and dispersion of analysts’ earnings forecasts, arguing that asset prices more reflect the views of optimistic investors because of short-sale constraints in equity markets. In this article, we examine whether a similar effect prevails in corporate bond markets. After controlling for common bond-level, firm-level, and macroeconomic variables, we find evidence that bonds of firms with higher dispersion demand significantly higher credit spreads than otherwise similar bonds and that changes in dispersion reliably predict changes in credit spreads. This evidence suggests a limited role of short-sale constraints in our corporate bond data sets. Consistent with a rational explanation, dispersion appears to proxy largely for future cash flow uncertainty in corporate bond markets.     

Estimation of market power in the presence of firm level inefficiencies

“The quiet life hypothesis” (QLH) by Hicks (1935) argues that, due to management’s subjective cost of reaching optimal profits, firms use their market power to allow inefficient allocation of resources. Increasing competitive pressure is therefore likely to force management to work harder to reach optimal profits. Another hypothesis, which also relates market power to efficiency is “the efficient structure hypothesis” (ESH) by Demsetz (1973). ESH argues that firms with superior efficiencies or technologies have lower costs and therefore higher profits. These firms are assumed to gain larger market shares which lead to higher concentration. Ignoring the efficiency levels of the firms in a market power model might cause both estimation and interpretation problems. Unfortunately, the literature on market power measurement largely ignores this relationship. In the context of a dynamic setting, we estimate the market power of US airlines in two city-pairs by both allowing inefficiencies of the firms and not allowing inefficiencies of the firms. Using industry level cost data, we estimate the cost function parameters and time-varying efficiencies. An instrumental variables version of the square root Kalman filter is used to estimate time-varying conduct parameters.     

Franchisees' trust in and satisfaction with franchise partnerships

This paper aims to establish the relationship between the antecedents of trust, trust itself, and franchisee satisfaction. Taking its cue from power-dependence, international business, and social exchange theories, the paper contributes to the franchise literature by offering a more comprehensive theoretical perspective to aid understanding of trust development in and satisfaction with franchise partnerships. Drawing on a multi-sector survey of Turkish franchisees, the study provides empirical evidence of the impact of the franchisors' role performance and cultural sensitivity on franchisees' trust in and satisfaction with franchise partnerships. Furthermore, this research demonstrates the central role of communication in the development of franchisees' trust.
