    E-commerce adoption in the retail sector: empirical insights
    (International Journal of Retail & Distribution Management, 2006) Nikolaeva, Ralitza
    Purpose of this paper To investigate the determinants of e-commerce adoption in the retail sector using duration analysis. Design/methodology/approach The study proposes a conceptual model based on technology adoption and population ecology models. It identifies specific determinant factors organized under three areas: perceived benefits, organizational readiness, and external influences. Duration analysis is applied to data on 392 retailers.

    Exploring curvilinearity through fractional polynomials in management research
    (Organizational Research Methods, Forthcoming, 2015) Nikolaeva, Ralitza; Bhatnagar, Amit; Ghose, Sanjoy
    Imprecise theories do not give enough guidelines for empirical analyses. A paradigmatic shift from linear to curvilinear relationships is necessary to advance management theories. Within the framework of the abductive generation of theories, the authors present a data exploratory technique for the identification of functional relationships between variables. Originating in medical-research, the method uses fractional polynomials to test for alternative curvilinear relationships. It is a compromise between non-parametric curve fitting and conventional polynomials. The multivariable fractional polynomial (MFP) technique is a good tool for exploratory research when theoretical knowledge is non-specific and thus, very useful in phenomena discovery. The authors conduct simulations to demonstrate MFP’s performance in various scenarios. The technique’s major benefit is the uncovering of non-traditional shapes that cannot be modeled by logarithmic or quadratic functions. While MFP is not suitable for small samples, there does not seem to be a downside of overfitting the data as the fitted curves are very close to the true ones. The authors call for a routine application of the procedure in exploratory studies involving medium and large sample sizes.

    Iinterorganizational imitation heuristics arising from cognitive frames
    (Journal of Business Research, 2012) Nikolaeva, Ralitza
    The literature on organizational imitation mostly disregards its cognitive aspect. Yet, imitation is a cognitive heuristic for complex strategic decisions. The current essay draws a unifying framework of different models of imitation through a cognitive lens in the context of innovation adoptions. It describes the interaction of the framing of imitation and the organization’s evaluation of an innovation. This interaction of threat and opportunity categorizations results in the use of various combinations of the two most popular imitation heuristics – “imitate the successful” and “imitate the majority” – as managers decide to copy predecessors in order to improve the status quo or to avoid losing it. Since the framings dictate different imitation timings, the speed of innovation diffusion depends on these interactions. However, as different cognitive frames may trigger the same heuristics, generalizations about the adoption motivation based on its timing can be unrealistic...

    Office design and dignity at work in the knowledge economy
    (Palgrave McMillan, 2016) Nikolaeva, Ralitza; Dello Russo, Silvia
    The current chapter looks at a grossly overlooked aspect affecting employee dignity in the workplace – the physical environment. While the knowledge economy has grown tremendously in the last four decades, researchers have not paid much attention to the new needs of the physical workspace despite the fact that office buildings represent the second largest financial overhead after human resource. At the same time, the physical space is a critical element in the organization of the processes, activities and ultimately the power structure of any organization.

    Online market entry: the motivations for imitation across retailer types
    (Managerial and Decision Economics, 2014) Bhatnagar, Amit; Nikolaeva, Ralitza; Ghose, Sanjoy
    This study examines the motivations for imitation in retailers’ online channel entry. Extant literature suggests that legitimacy and efficiency are the primary motivators for firms to imitate. We develop hypotheses which center on the belief that not all firm types would use the same motivator for deciding to imitate and enter the online market; legitimacy would be the driving force for some retailer types while efficiency would be the motivator for others. We test our hypotheses on a unique data collected from multiple sources. Our findings confirm that the motivators for imitation vary across retailer types.

    The dynamic nature of survival determinants in e-commerce
    (Journal of the Academy of Marketing Science, 2007-12-01) Nikolaeva, Ralitza
    The dynamic effects of survival determinants in e-commerce are tested using longitudinal data on 460 e-tailers. This is achieved through the incorporation of both time-varying covariates and coefficients in a discrete hazard rate model. The model includes elements of competitive strategy, industry structure, firm and product characteristics, and the macro environment. The study demonstrates the changing effect over time of factors affecting survival. For example, order of entry advantages are observed, but they are short-lived. This finding shows that e-tailers cannot rely on early entry as a strategic move in the long run. E-tailers with more media presence seem to survive longer. Being publicly traded and selling products with digital characteristics present advantages for e-tailers only in the beginning years, but they are not sustainable over long time periods. Survival chances decrease with higher competitive density, market growth rate, and equity market level at the time of entry. Conversely, economic growth tends to increase survival chances. The study also finds an inverted-U relationship between the hazard of exit and firm age. The conclusion section discusses the implications of the timevarying nature of survival determinants.

    The dynamic nature of survival determinants in e-commerce
    (2006-03) Nikolaeva, Ralitza
    Longitudinal data on 460 e-tailers are used to test the dynamic effects of survival determinants in e-commerce. The model includes elements of competitive strategy, industry structure, firm and product characteristics, and the macro environment. The study demonstrates that very few of the factors affecting survival have a constant effect over time. For example, order of entry advantages are observed, but they are short-lived meaning that etailers cannot rely on early entry as a strategic move in the long run. This finding reconciles the arguments about the existence of pioneering advantages in the empirical literature. Retailers benefit from multiple channels throughout their lives...
