Criterion-robust optimal product designs for discrimination between nested response surface models

Consider the problem of discriminating between two rival response surface models and estimating parameters in the identified model. To construct designs serving for both model discrimination and parameter estimation, the M _γ-optimality criterion, which puts weight γ (0≤γ≤1) for model discrimination and 1 − γ for parameter estimation, is adopted. The corresponding M _γ-optimal product design is explicitly derived in terms of canonical moments. With the application of the maximin principle on the M _γ-efficiency of any M _γ'-optimal product design, a criterion-robust optimal product design is proposed.     

Hedonic price estimation for the Turkish bread wheat characteristics

This research has been made to assess the effects of the characteristics of bread wheat quality on the prices in the Turkish bread wheat market. A hedonic price model was used to analyze factors affecting the variability in bread wheat prices. Results indicate that prices received by bread wheat producers reflect the presence of basic quality characteristics of bread wheat. According to the research consequences, the hectoliter and sedimentation are the major factors that have the greatest effect and influence on Turkish bread wheat market in respect to the quality aspects. The study shows that the five regions in Turkey, which have been chosen as the research area and are important in bread wheat production, have differences in terms of bread wheat quality characteristics.     

Understanding relationship quality and online purchase intention in e-tourism: A qualitative application

This study explores the formation of relationship quality and online purchase intention in the service context of tourism, and a model is also introduced. This study tries to conceptualize a model based on a mediating mechanism of relationship quality that may be applied to understand online purchase intention in tourism. Learning the critical role of relationship quality in e-tourism can guide tour service providers to design different strategies for different online customers, and consequently achieve high customer online purchase to tourist service and product. In the proposed model of this study, the perceived incentive, perceived service quality, perceived ease of purchasing and perceived usefulness influence customer online purchase intention indirectly via the mediation of relationship quality. Additionally, five propositions are derived accordingly based on the proposed model and literature review. Finally, discussion, limitation and future research are also provided.     

Lies,damned lies and statistics: the accuracy of survey responses

That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper here considers research upon corporate environmental reporting. It compares information provided by corporate environmental reports with information that survey respondents claim their organization’s environmental report contains. This enables the accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report information that is, in fact, actually reported.     

Stochastic better-reply dynamics in finite games

In this paper, we analyze a model where individuals from finite populations are repeatedly drawn to play a finite game and in every period choose a weakly better reply to a sample distribution from a finite history of past play. For all finite games and sufficiently incomplete information, we prove convergence to minimal sets closed under better replies. This result complements previous findings in a deterministic continuous-time framework and implies convergence to strict Nash equilibria in many well-known classes of games.     

Demand for redistribution,support for the welfare state,and party identification in Austria

This paper describes subjective wage inequality and the demand for redistribution in Austria using individuals’ estimates of occupational wages from the International Social Survey Program. Although these estimates differ widely across individuals, the data clearly show that most individuals would like to decrease wage inequality, relative to the level of inequality which they perceive to exist. The empirical analysis also shows that the demand for redistribution is strongly associated not only with variables describing self-interested motives for redistribution, but also with perceptions of and social norms with respect to inequality. Further, the demand for redistribution is a strong predictor for whether an individual is supportive of redistribution by the state. On the other hand, however, I find almost no evidence for an empirical association between the demand for redistribution and individuals’ party identification.     

Location and competition in retail banking

We investigate the impact of banking deregulation during the 1990s on consumer welfare. We estimate a spatial model of consumer demand for retail bank deposits that explicitly accounts for consumer disutility from distance traveled. This is important given the substantial changes in banks' branch networks observed in the data. Our model indicates that cross-price elasticities between banks whose branches are close to consumers (‘close’ banks) are larger than those between ‘far’ banks and more than double the cross-price elasticity of ‘close’ banks with respect to ‘far’ banks. We distinguish between thrifts and other banks and find that within-thrift competitive effects are stronger than within-bank effects or those between thrifts and banks. We use our estimates to predict the effect of changes in market structure on consumer welfare following the branching deregulation of the Riegle–Neal Act of 1994. Our results indicate that the median household gained around $60 per year from the changes. Approximately two thirds of the gains come from within-market changes in market structure. The gains were greater in markets with high initial numbers of banks than elsewhere.     

The long-run impact of ICT

This paper examines the growth impact of digital capital in the US and the EU-15 countries from a long-run perspective. It estimates the elasticity of output with respect to Information and Communication Technology (ICT) within a production function framework, by means of a panel cointegration analysis. ICT capital is found to significantly spur GDP growth over time, and above its income share. This sharply contrasts with existing aggregate evidence, and with the view that the growth impact of this factor is confined to the contribution given to the productivity resurgence of the 1990s.     

Testing the higher education-led growth hypothesis in a small island: an empirical investigation from a new version of the Solow growth model

This study employs a new version of the Solow Growth Model in order to investigate the higher education-led growth (HELG) hypothesis in the case of North Cyprus. Results reveal that a long-run equilibrium relationship exists between real income growth of North Cyprus and its determinants, namely capital, labor, and the higher education sector. Results show that real income growth converges to its long-term equilibrium level by 10.9 %. Granger causality tests suggest undirectional causality from higher education growth to real income growth in North Cyprus. Therefore, the HELG hypothesis can be inferred for the Turkish Cypriot economy.
