Investigating the roles of online buzz for new product diffusion and its cross-country dynamics

This research investigates the roles of online buzz activities in influencing the speed and scope of new product diffusion and also the interactive dynamics of online buzz activities within and across countries. This study applies a diffusion model with two latent adopters and a log linear model to monthly sales and online messages collected from major online communication sites in five different countries. The empirical study evaluates two different roles of online buzz: (1) accelerating the new product diffusion process by influencing imitation tendency; and (2) expanding potential market size. In addition, the empirical study shows the interactive dynamics of online buzz activities within and across countries, and provides some information on what encourages online buzz activities, and how they interact with each other within a country and across countries.     

Studying the level-effect in conjoint analysis: An application of efficient experimental designs for hyper-parameter estimation

Research in marketing, and business in general, involves understanding when effect-sizes are expected to be large and when they are expected to be small. An example is the understanding of the level-effect in marketing, where the effect of product attributes on utility is positively related to the number of levels present among choice alternatives. Knowing when consumers are sensitive to the competing levels of attributes is an important aspect of merchandising, selling and promotion. In this paper, we propose a model and a method for studying the level-effect in conjoint analysis. The model combines perceptual theories in psychology to arrive at a non-linear specification of hyper-parameters in a hierarchical model. The method applies an experimental design criterion for efficient estimation of hyper-parameters. The proposed model and method are validated using a national sample of respondents.      

Note: A new approach to the modeling of spatially dependent and heterogeneous geographical regions

We propose a new spatial modeling approach to calibrate the potential impact of spatial dependency and heterogeneity on the underlying drivers of customer service and/or satisfaction measurement. The newly proposed procedure derives regionally varying coefficients, provides more flexible fitting, improves calibration fit and predictive validation, and can potentially result in augmented managerial implications compared to existing procedures by utilizing a hierarchical Bayes framework with geographical boundary effects. Using synthetic datasets, we illustrate how the proposed model outperforms four relevant benchmark models including ordinary linear regression, a Spatially Dependent Segmentation model (Govind, Rabikar, and Mittal 2018), classic Geographically Weighted Regression, and Bayesian Geographically Weighted Regression. The improved performance is most prominent when there exist significant differences between geographic boundaries and/or irregular patterns of observation locations. In our automobile customer satisfaction application study, the proposed approach also demonstrates favorable performance compared to these benchmark models. We find a dramatically heterogeneous pattern regarding two covariates in the Mountain U.S. geographic division: dealership service is more important in urban areas (e.g., Phoenix, Salt Lake City and Denver) than in rural areas, but vice-versa concerning vehicle quality.     

Are consumers heterogeneous in their preferences for odd and even prices? Findings from a choice-based conjoint study

While marketing theories provide some justification for the common practice of setting 9-ending prices, the results of empirical studies are not conclusive on the effects of odd pricing. Nearly all empirical studies have been conducted at the aggregate consumer level, thereby implicitly assuming that consumers respond to odd prices homogeneously. In this research, we analyze consumers' preferences for 9-ending versus 0-ending prices at the individual level. Our findings suggest that some consumers strongly prefer 9-ending prices, whereas other consumers favor 0-ending prices. We further address the existence of level effects and investigate the influence of consumer characteristics on preferences for odd prices.     

Introducing management models in service organisations in developed and developing countries

The aim of this paper is to examine the application of the European Foundation for Quality Management model for self-assessment as a means to introduce changes in management in services in higher education institutions (HEIs) in Spain and in Jordan. This paper uses the case study methodology on eight administrative services in a public university in Spain and seven university services in two Jordanian universities, a public and a private institution. The findings show the steps that an administrative service may follow in order to apply the questionnaire approach successfully in a reform process, the difficulties, the benefits and the success factors in both countries and the consequences of the changes introduced. The study provides lessons for decision makers and managers from other universities in developed and developing countries, who wish to introduce the practice of quality management by creative means. This paper extends knowledge on self-assessment (steps, difficulties, benefits, success factors and changes in management) to services in HEIs.     

Modeling recovery rates of corporate defaulted bonds in developed and developing countries

This paper examines the determinants of recovery rates of corporate defaulted bonds in the emerging markets. We use data on defaulted bonds from Moody's ultimate recovery database over the period 2005–2015 to experiment the impact of the borrower characteristics added to the macroeconomic and the bond market conditions on recovery rates. We find evidence that bond recovery rates in emerging and developed countries do not depend on the same factors. Our results show that bond recovery rates in developing countries seem to depend much more on specific characteristics of firms. The financial crisis has affected more significantly subordinated bond recovery rates than secured bonds in emerging markets.     

The impact of direct-to-consumer advertising of prescription drugs on physician visits and drug requests: Empirical findings and public policy implications

This study analyzes the effect of DTCA expenditures for anti-hyperlipidemia drugs on patient behaviors. The key findings are: (a) DTCA expenditures have a positive and long-term effect on the number of visits to physicians by newly diagnosed hyperlipidemia patients. (b) The effectiveness of DTCA in generating new patient visits varies substantially across patient sub-groups. (c) The effect of DTCA is larger on drug visits than on non-drug-only visits. (d) Own-brand DTCA expenditures increase the number of patient requests for Lipitor and Zocor, but have no effect on patient requests for Pravachol. Competing drugs’ DTCA expenditures have a positive effect only on patient requests for the leading brand, Lipitor. (e) A cost-effectiveness analysis suggests that the economic benefits of DTCA in terms of life years saved by preventing cardiovascular disease are considerably larger than the costs of advertising. (f) DTCA on TV has strong effects on underserved segments of the population, such as those on Medicaid. We believe this finding should be carefully considered by proponents of a complete ban or stricter regulations on DTCA.     

On the relationship between public and private spending in developing and developed countries

Using annual data, the paper studies the time-series evidence regarding the effectiveness of government spending. The emphasis is on the relationship between public spending and private spending. The objective is to identify whether the effects of public spending on macro variables are reinforced or mitigated through the spillover effects on private spending. The evidence attests to the importance of stimulating private spending to maximize the positive effect of an increase in public spending on real growth. Concerns about the crowding out effects of higher public spending on private demand are more dominant in developing countries. Moreover, the scope for government spending to determine aggregate uncertainty is much larger in developing countries. Overall, the evidence attests to the importance of managing trends and variability of government spending towards maximizing the fiscal multiplier. The paper's evidence spells out potential to maximize the fiscal multiplier via private spending and concerns about the ineffectiveness of fiscal policy where crowding out concerns dominate.     

State of the science: violence prevention efforts in developing and developed countries

Violence is an important global public health problem that claims the lives of over 1.6 million people each year and results in numerous other health and social consequences. It is also a preventable health problem. This paper provides an overview of the current status of prevention efforts in developing and developed countries, describes what is known about the effectiveness of different approaches and highlights some of the important challenges in building the evidence-base for violence prevention programmes. Research conducted to date shows an imbalance in the emphasis of prevention programmes across the different types of violence. This imbalance is reflected in the timing of response, the nature and level of influence of interventions and programmes and the outcomes studied. Promising and effective approaches have been identified, but many more still require rigorous testing, particularly in developing countries. The current state of the science in violence prevention reveals both progress and a number of remaining challenges.     

Performance of international joint ventures from developing and developed countries: An empirical study in a developing country context

In response to the need for research on International Joint Ventures (IJVs) from developing countries, this paper examines the multivariate determinants of performance of 59 IJVs from both developing and developed countries in a developing country context. Resource complementarity, cooperation, joint venture experience, technology and export-orientation were found to be significant determinants of performance of joint ventures. While the determinants varied for IIVs from developing and developed countries, there were no significant differences in their performance levels. The empirical findings and their implications, including limitations and areas for further research are discussed.

Government Programs and Diffusion of Innovations in Taiwan: An Empirical Study of Household Technology Adoption Rates

ABSTRACT

This research mirrors Olshavsky's (1980) groundbreaking study by using penetration data for household technologies in Taiwan. Results support conventional wisdom that adoption rates are increasing over time. Moreover, rates were negatively associated with price. This research goes beyond Olshavsky by examining whether adoption rates differ across geographical regions types (i.e., rural, townships, and metropolitan). Adoption rates for nine household technologies at the three geographical types are not significantly different. Support is lent to the proposition that government rural development policies promoting education and physical infrastructures have fostered relatively equal diffusion patterns of household technologies in Taiwan.     

Incorporating heterogeneous adoption rates in new product diffusion: A model and empirical investigations

This paper presents a stochastic model of the adoption process for durables that explicitly incorporates heterogeneity in adoption rates among the consumers. The model assumes that the individual adoption times follow the Weibull distribution. Heterogeneity in adoption rates is represented by the gamma distribution. The resulting Burr distribution is more general than the Bass model, fits data as well as the Bass model estimated using OLS regression, and has parameters that can be used to make inferences about individual adoption behavior without being influenced by spurious aggregation effects.Special thanks are due to Professor Donald Lehmann for providing numerous suggestions and encouragement at all stages of the study. Thanks are also due to Professors David Schmittlein and Richard Colombo and two anonymous reviewers for helpful comments on an earlier draft of the paper.     

An exploratory study of characteristics and attributes of Turkish entrepreneurs: A cross-country comparison to Irish entrepreneurs

There has been limited research on entrepreneurship in Turkey. Given the fact that globalization has rapidly been increasing, that foreign direct investment is spreading throughout the world, and that more and more foreign investors are seeking partners in emergent markets such as Turkey. One important reason for the interest in Turkish entrepreneurs is because they have many characteristics that are similar to entrepreneurs in Western markets. Even if there are many differences between Western entrepreneurs and Turkish entrepreneurs, it would be valuable to compare the characteristics of Turkish entrepreneurs with others. Moreover, a few cross-cultural studies have examined the similarities among entrepreneurs in various nations. Ireland and Turkey have many striking similarities despite varying cultural backgrounds. Hence, this empirical research was undertaken to investigate the characteristics and attributes of Turkish entrepreneurs and compare them to Irish entrepreneurs. The research design in this study focused on 161 Turkish entrepreneurs who were randomly selected from a list (obtained from local Chamber of Commerce) and interviewed using a structured questionnaire. The questions assessed relevant areas, such as demographic and business information, motivations, entrepreneurial characteristics, business problems, personality characteristics, and management skills. Information on the Irish entrepreneurs was incorporated from a published study. Overall, in terms of entrepreneurial characteristics, Turkish entrepreneurs displayed surprisingly similar characteristics to the Irish. The implications of this study are discussed along with some recommendations.     

Environmental determinants of U.S. foreign direct investment in developed and developing countries: A structural analysis

This study attempts to explain theoretically and empirically the influence of developed and developing countries’ environments on foreign direct investment from the United States. It is postulated that foreign direct investment into these economies can be explained by examining interactions among three environmental constructs: technological development, quality of life, and political instability. A structural equation model is developed to test the concurrent and longitudinal influence of the three environmental constructs on foreign direct investment into these economies from the United States.     

Migrants and multinational firms: The role of institutional affinity and connectedness in FDI

We examine how, and to what extent, migrants in a host country attract foreign direct investment (FDI) from firms based in their country of origin (CO). Introducing the notion of institutional affinity, we argue that increased institutional affinity and increased connectedness of institutional environments of migrants’ CO and country of residence, make a location attractive to CO firms. Empirical analysis of FDI and migration panel data shows that in addition to the traditional factors influencing FDI patterns, there is a collective migrant effect on FDI, and this effect is statistically significant and economically meaningful for migrants from developing countries.     

International heterogeneity in the associations of new business models and broadband Internet with music revenue and piracy

Broadband Internet has fundamentally changed business models in many industries. In the music industry, for instance, old business models were challenged by illegal competitors, and broadband Internet has enabled value creation through new business models. The changes that established business models experienced in the wake of broadband Internet, however, differed vastly across national markets, and these differences are not well understood. We build a conceptual framework and study the extent to which differences in economic and cultural factors are associated with different market outcomes in the wake of the proliferation of broadband Internet. Thus, we compile two unique data sets from the music industry, comprising (1) revenue data for 36 countries and 22 years and (2) piracy data for 47 countries and >2 years. We use a Bayesian multilevel model to explore between-country heterogeneity in the associations between these variables and broadband Internet adoption and business model innovations. Our results show that the negative association between broadband Internet penetration and music revenue is weaker in high-income countries, where income restrictions are less likely to drive demand towards illegitimate piracy services. In terms of cultural factors, we find that a market's response to the introduction of broadband Internet is less negative in countries scoring high on Hofstede's individualism and uncertainty avoidance dimensions. Furthermore, we find that overall revenues only recover after the latest generation of streaming services (e.g., Spotify) has been introduced, and the adoption of these services is associated with lower levels of online music piracy.     

An investigation of consumer intention to use pick-up point services for last-mile distribution in a developing country

Pick-up point services are one response to last-mile distribution challenges in the e-commerce growth scenario. However, in large cities in developing countries where the low-income and high-income groups are clearly divided, differences in consumer behavior between income groups may affect service distribution. The literature shows that most consumers may use pick-up points when available. However, the service implementation is facing huge inertia. A survey was carried out with 396 consumers in São Paulo, and a conceptual framework was proposed to expand the Diffusion of Innovation Theory to reveal these behaviors. Data were accessed using advanced structural equation modeling techniques (Multigroup and IPMA) to conduct a case study. The findings suggest that ‘Trialability’, ‘Compatibility’, and ‘Relative advantage’ constructs most affect consumer behavior. Location security and accessibility are matters of great concern. The higher preference to use the pick-up point system comes from low-income consumers (social classes D and E); almost 96% of them reported being affected by delivery issues. They also prefer personal attendance and supermarkets as safe and accessible locations. Higher social classes (A and B) still prefer home delivery. This research will help retailers to understand how to operate in a given market to provide an effective, fair, and sustainable service, promoting its diffusion.     

Retail bank selection in developed and developing countries: A cross‐national study of students' bank‐selection criteria

This exploratory research article is concerned with students' selection of retail banks in the United States and Ghana. It is a comparative cross‐national study aimed at revealing the factors determining retail bank selection among students in different environmental settings. The key objective is to establish if there are any significant differences and/or similarities in students' selection of retail banks in developed and developing economies. A similar data‐collection method was employed in the United States and Ghana to facilitate constructive comparison. The results identified four key factors—convenience, competence, recommendation by parents, and free banking and/or no bank charges—to be consistent across the two economies. The recommendation of the study is that in the context of an open and liberalized market environment, retail bank marketing strategies should be standardized irrespective of the national development stage. It concludes that retail bank managers particularly in developing countries should learn to provide consistent and good customer care. © 2009 Wiley Periodicals, Inc.     

Profiling consumers based on information use and trust in a developing economy

In the wake of the intense debate about the effect of poultry imports on domestic poultry industries in sub‐Saharan Africa, information campaigns have evolved to encourage the consumption of domestic poultry meat products. Nevertheless, consumers use numerous channels to find information, and thus, the extent to which resources should be allocated to these channels to reach segments of consumers is vital. The purpose of this paper is to identify consumer groups based on use and trust in information sources and then profile the segments using sociodemographic variables, purchase motives, and meat consumption. Face‐to‐face interviews were used to collect data amongst 500 urban consumers in Ghana, which were analysed with factor analysis and two‐step cluster analysis. Results show that consumers frequently use personal sources of information about chicken. Cluster analysis revealed three consumer segments: cautious consumers (18.2%), enthusiastic consumers (53.0%), and optimistic consumers (28.8%). The segments differed significantly regarding the type of information searched for, sociodemographic characteristics, purchase motives, and chicken meat consumption patterns. The findings can aid actors and institutions seeking to increase the consumption of domestic poultry meat in developing targeted communication strategies that suit the characteristics, motivations, and information needs of different consumers.
