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.     

A conduct parameter model of price discrimination

We consider a conduct parameter model where firms price discriminate based on the consumers’ willingness to pay. For any conduct, the average price is invariant to the extent of price discrimination. Moreover, when the number of prices goes to infinity, there is a linear relationship between market power, measured by conduct, and range of offered prices. Hence, when the firms face competition, some of the high valuation customers are charged below their valuations, which contrasts with perfect price discrimination results for a monopoly.     

Marketing strategies of ethnic minority businesses in the UK

This paper seeks to evaluate the influence of the entrepreneurs' educational backgrounds, the firm's target market, and the sector of operations on the marketing practices of Turkish ethnic minority businesses. The paper reports and analyses the findings of 227 face-to-face structured interviews with Turkish small business owners. The findings of the study indicate that Turkish ethnic minority businesses operating in different sectors use both transactional and relational approaches to marketing. Their choices of pursuing different marketing strategies are influenced by the entrepreneurs' educational backgrounds, the firm's target market, and the sector of operations.     

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.     

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.     

Politics and sustainable tourism development – Can they co-exist? Voices from North Cyprus

This paper investigates ways in which political obstacles inhibit the formulation and implementation of sustainable tourism development in small-island developing states through the example of North Cyprus. The methodology draws on in-depth interviews and participant observation of significant actors in the tourism sector. The research findings suggest that understanding the intricate political system and power structure in a society is the key to understanding sustainable tourism policy development, planning and implementation. In the case of North Cyprus, policy development was found to be a product of political influence (referred to as ego-driven politics in the text), specifically the use of public resources as an instrument for political power, retention and that the politicisation of the public sector is the underlying cause of the weakened progress in sustainable tourism development. It is therefore essential to have a clear understanding of political issues, key political actors’ interests and how to mitigate personal interests to facilitate and maintain sustainable tourism development in such small states.     

Is volatility risk priced in the securities market? Evidence from S&P 500 index options

The authors examine whether volatility risk is a priced risk factor in securities returns. Zero‐beta at‐the‐money straddle returns of the S&P 500 index are used to measure volatility risk. It is demonstrated that volatility risk captures time variation in the stochastic discount factor. The results suggest that straddle returns are important conditioning variables in asset pricing, and investors use straddle returns when forming their expectations about securities returns. One interesting finding is that different classes of firms react differently to volatility risk. For example, small firms and value firms have negative and significant volatility coefficients, whereas big firms and growth firms have positive and significant volatility coefficients during high‐volatility periods, indicating that investors see these latter firms as hedges against volatile states of the economy. Overall, these findings have important implications for portfolio formation, risk management, and hedging strategies. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:617–642, 2007     

The influence of family tradition and psychological traits on entrepreneurial intention

This paper investigates the influence of family tradition and psychological traits on the entrepreneurial intention of university hospitality students in the UK. The empirical study was predicated on the need to consider both socio-demographic variables and especially family background and personality traits. The research also tested the suggestion that risk taking propensity may act as a potential mediator. The findings of the study suggest that family entrepreneurial background and innovation influence the intention to start a new business; that there is positive relationship between tolerance of ambiguity and risk taking propensity; and a negative relationship between locus of control and risk taking propensity. The paper emphasizes the importance of taking a more holistic approach when researching the factors that influence entrepreneurial intention.     

Revisiting the convergence hypothesis for tourism markets: Evidence from Turkey using the pairwise approach

This paper empirically revisits the tourism markets convergence hypothesis (Narayan, 2006) for the case of Turkey by employing the newly developed pairwise approach to the analysis of stochastic convergence ( [Pesaran, 2007] and [Pesaran et?al., 2009]). This new approach allows for unit root tests to be conducted on all possible pairs of tourist arrival differentials across Turkey’s 20 major tourist source markets, thus avoiding the need to choose a base source market or total tourist arrivals figure as the benchmark. Using monthly data over the period January 1996 to December 2009, the main finding is that despite considerable ‘co-movement’ of international tourist arrivals in Turkey, there is no evidence of long-run ‘convergence’ among Turkey’s major tourism markets. Cluster-based club convergence analyses alongside bivariate pairwise estimations confirm the lack of convergence and highlight specific tourist source markets with considerable untapped potential. These findings have profound policy implications for Turkey’s inbound tourism planning and promotion.
