Consumers' awareness,acceptance and attitudes towards functional foods in Turkey

The aim of the present study was to investigate consumers' awareness, acceptance and attitudes towards functional foods in Turkey. Eight hundred and eight people participated in this study: aged between 20 and 80 years, 38.5% were male and 61.5% were female. Participants were given a questionnaire and were asked to fill it in by themselves to minimize the influence of the interviewer. Results indicated that socio‐demographic characteristics such as age, education level and income level are important indicators of consumers' awareness and consumption of functional food. The results show that the female respondents were 2.987 times more aware of functional food than the male respondents. Similarly, the likelihood of respondents having awareness of functional food was 1.431 times greater among those who had a higher educational level than among those with a lower educational level. Consumers who used vitamin supplements were 1.228 times more aware of functional food than other consumers. The results show that older respondents were 3.395 times more aware of functional food than younger respondents. Respondents with a history of familial diseases were more likely than others to have consumed margarine with plant sterol, fruit juices fortified with vitamin C, and breakfast cereals fortified with vitamins and minerals. Those with a diet‐related problem were more likely to have consumed cholesterol‐lowering products than those without a problem. As a conclusion, this study has shown that socio‐demographic characteristics such as age, education and income levels, and prices are important indicators that influence consumers' awareness and consumption of functional food. These results suggest that this type of knowledge could affect consumers' interest in functional foods, and therefore educational strategies might be necessary to encourage the consumption of functional foods.     

Consolidation and commercial bank net interest margins: Evidence from the old and new European Union members and candidate countries

This paper examines the effects of financial reforms on the determinants of commercial bank net interest margin in the banking systems of the new EU member countries and candidate countries by dividing the sample period (1995–2006) into two sub-periods: consolidation period (1995–2000) and post-consolidation period (2001–2006). The paper also compares the new and old EU members to check whether differences with respect to the determinants of net interest margins between these two groups of countries exist within the same time period. The results indicate that size and managerial efficiency are negatively and significantly related to net interest margins in the two sub-periods. Regulators should promote merger and acquisition and market entry in order to increase the scale and efficiency of banks operating in the sector. Exploitation of the scale economies seems to be important in decreasing the interest rate spread in the sampled banking sectors. The results further indicate that all macroeconomic variables are statistically insignificant in the second sub-period, suggesting that differences in macroeconomic fundamentals have decreased among the sampled countries due to the increased convergence process in recent years. As for the comparison of the new and old EU members, the results suggest that the financial and economic convergence between the new and old members has not been completed. Macroeconomic differences within the group and between the groups still exist.     

Equilibria in second price auctions with participation costs

We investigate equilibria of sealed-bid second price auctions with bidder participation costs in the independent private values environment. We focus on equilibria in cutoff strategies (participate and bid the valuation iff it is greater than the cutoff), since if a bidder finds it optimal to participate, she cannot do better than bidding her valuation. When bidders are symmetric, concavity (strict convexity) of the cumulative distribution function from which the valuations are drawn is a sufficient condition for uniqueness (multiplicity) within this class. We also study a special case with asymmetric bidders and show that concavity/convexity plays a similar role.     

Ratifiability of efficient collusive mechanisms in second-price auctions with participation costs

We investigate whether efficient collusive bidding mechanisms are affected by potential information leakage from bidders' decisions to participate in them within the independent private values setting. We apply the concept of ratifiability introduced by Cramton and Palfrey [Cramton, P.C., Palfrey, T.R., 1995, Ratifiable mechanisms: Learning from disagreement, Games Econ. Behav. 10 (2), 255–283] and show that when the seller uses a second-price auction with participation costs, the standard efficient cartel mechanisms such as pre-auction knockouts analyzed in the literature will not be ratified by cartel members. A high-value bidder benefits from vetoing the cartel mechanism since doing so sends a credible signal that she has high value, which in turn discourages other bidders from participating in the seller's auction.     

The prioritisation of service dimensions in logistics centres: a fuzzy quality function deployment methodology

This study takes a customer focus that prioritises the service-offering dimensions of logistics centres (LCs) by considering potential LC customer expectations. Applying a survey and a quality function deployment methodology to logistics service providers, the study explores, categorises and prioritises LC customer expectations and LC service characteristics. The results indicate that customer preferences mainly prioritise infrastructure, and warehouse and intermodal dimensions. However, when the cost dimension is included, higher utility values are delivered through soft service dimensions like value-added or standard services. LC investors or undertakers can use these results to guide their design of market offerings by using the same methodology to assess expectations in their target markets.     

The hidden cost of smoking: Rent premia in the housing market

In this article, we provide novel evidence on the additional costs associated with smoking. While it may not be surprising that smokers pay a rent premium, we are the first to quantify the size of this premium. Our approach is innovative in that we use text mining methods that extract implicit information on landlords’ attitudes to smoking directly from Zoopla UK rental listings. Applying hedonic, matching, and machine-learning methods to the text-mined data, we find a positive smoking rent premium of around 6%. This translates into £14.40 of indirect costs, in addition to £40 of weekly spending on cigarettes estimated for an average smoker in the United Kingdom.     

Chief technology officer roles and performance

This paper assesses the impact of Chief Technology Officers (CTO) on firm performance using upper-echelon theory, human capital theory and social capital theory. The upper-echelon theory is used to investigate how CTO roles are realised within a company regardless of the individual who carries them out, i.e. through a formal CTO position or not. Human and social capital theories are employed to assess how certain features of CTO influences his/her effect on company performance. Thus, this explorative study investigates two questions: (1) do CTO roles affect a firm's performance?, and (2) which features of the senior manager in charge of technology influence performance? To answer these questions the study first develops a conceptual model and subsequently tests the model based on a survey of 49 firms in electronics and machinery industries in Turkey. Two findings emerge: (1) the fulfilment of CTO roles increases a firm's profitability and (2) the existence of a distinct managerial technology position further improves profitability. Moreover, the study clearly shows the role of social capital theory in explaining how the company performance is likely to increase when the CTO/CTO-proxy manager is placed on a higher rung on the organisational ladder.     

A model of evidence production and optimal standard of proof and penalty in criminal trials

The defendant is either innocent or guilty, which she, not the court or prosecutor, knows. The court convicts the defendant whenever its posterior probability of her guilt – which depends on the evidence presented – is greater than the standard of proof. Evidence production by litigating parties is a costly stochastic process. Subsequently, the optimal choice of standard of proof and penalty is analysed. The optimal standard of proof is increasing in the cost of convicting an innocent defendant and decreasing in the cost of acquitting a guilty defendant. Higher penalties may increase probabilities of both false conviction and false acquittal. Un modèle de production de la preuve et la norme optimale de la preuve et de la punition dans les procès criminels. On développe un modèle de production de la preuve par les parties en litige dans un contexte criminel. L’accusé peut être de deux types – innocent ou coupable – et il sait de quel type il est. Mais ni le tribunal ni le procureur n’ont cette information. Le tribunal ne va condamner l’accusé que si la probabilité a posteriori de culpabilité de l’accusé est plus grande qu’une certaine valeur seuil – la norme de la preuve. Cette probabilité dépend des preuves présentées par les parties au tribunal. La production de la preuve est un processus stochastique coûteux. Ce modèle de production de la preuve est utilisé pour analyser le choix optimal de la preuve et de la punition. Comme on pouvait s’y attendre, on peut montrer que la norme optimale de la preuve s’accroît à proportion que s’accroît le coût de condamner un innocent et décroît à proportion que s’accroît le coût de l’acquittement d’un coupable. Ce qui est plus surprenant, on peut montrer que l’accroissement de la punition infligée à un accusé trouvé coupable peut accroître les probabilités à la fois de condamnation et d’acquittement non fondés.     

Multi-layer quality function deployment (QFD) approach for improving the compromised quality satisfaction under the agency problem: A 3D QFD design for the asset selection problem in the shipping industry

The aim of this paper is to improve the quality function deployment (QFD) method by utilizing requirements of both the major customer and the service provider. The QFD method was first applied to the shipbuilding industry and the main goal of the method is to improve the production processes by using customer requirements in connection with the related technical measures of the product. However, one of the critical criticisms of the QFD is based on the lack of proper budget assessment and the satisfaction of the producer (or service provider). The multi-layer QFD design is proposed to collect responses from both customer and the service provider so as to ensure satisfaction of all parties including financial feasibility of the intended improvements. Hence, the agency problem between parties will be eliminated.
