Yayın Hegemony of network capabilities, frugal innovation and innovation strategies: The innovation performance perspective(MDPI, 2021) Haffar, Mohamed; Özcan, Rasim; Radulescu, Magdalena; Isac, Nicoleta; Nassani, Abdelmohsen A.; Özcan, Rasim; Yönetim Bilimleri Fakültesi, İktisat BölümüThe emergence of advanced technologies has brought new challenges and opportunities for all kinds of business organizations. In a technologically advanced era, innovation plays a dominant role for the successful operation of the commercial landscape. Therefore, the current study was conducted to investigate the impact of network capabilities (NC) and frugal innovation (FI) on innovation performance (IP). Furthermore, the mediating role of FI and moderating role of innovation strategies has also been tested on the link between NC and IP. Small and medium enterprises (SMEs) registered with small and medium enterprises development authorities (SMEDA) were approached for the completion of the current study. Only 509 owner/managers agreed to participate. A quantitative research design was employed for the current study. During the two–three months process of data collection only 387 complete responses were received from the SMEs working in Pakistan’s big cities. Correlation, regression and bootstrap methods were applied to test the study hypotheses. The findings revealed that NC positively affect FI and IP. Furthermore, the findings also confirmed the mediating effect of FI between NC and IP link. The performance of SMEs working in emerging economies is largely based on their innovative activities. In this dynamic scenario SMEs’ survival is attached to continuous IP in their products and services.Yayın On the ranks of tests having null of cointegration: A Monte Carlo comparison(Research Center Public ADM & Public Service, 2020) Khan, Asad ul Islam; Khan, Asad ul Islam; Isac, Nicoleta; Dobrin, Cosmin; Hussan, Mehmood; Khan, Asad ul Islam; Marin, Alina-Andreea; Yönetim Bilimleri Fakültesi, İktisat Bölümü; Yönetim Bilimleri Fakültesi, İktisat BölümüThe null of cointegration tests for testing the existence of cointegration are available in literature in great diversity. The selection of a particular test from all these available tests is the crucial problem and often researchers face this. This study is carried out to solve this problem by comparing eight tests on basis two properties of size and power using a new proposed methodology of rank scores. Three different specifications of deterministic component and four sample sizes are considered. It is concluded that if asymptotic critical values are used then it results into an uncontrolled empirical size. While, if the simulated critical values are used, then the empirical size is controlled around nominal size. Moreover, on basis of power, a simple test, which is based on KPSS statistic, is the sole better performer for all of the different 132 different cases of data generations considered in the study.Yayın Parallelisms between individual and organizational career(ECOFORUM, 2021) Isac, Nicoleta; Badshah, Waqar; Yönetim Bilimleri Fakültesi, İktisat BölümüIn the conditions of the competitive economy, a special role has the capitalization of the human and the managerial potential. Career management aims at planning and modeling the progress of employees within the organization in relation to the needs assessments of the organization, but also in relation to the performance of the potential and individual preferences of employees. Career involves the interaction between organizational and individual factors and this paper presents the parallelism between organizational career management (OCM) and individual career management (ICM). The purpose of this paper is to study the theoretical and applied aspects of the career. In order to highlight these aspects, a research was undertaken within an organization, which allowed the study of the career process and the major influencing factors.Yayın The probabilities of type I and II error of null of cointegration tests: A Monte Carlo comparison(Plos One, 2022) Khan, Asad ul Islam; Khan, Asad ul Islam; Aysan, Ahmet Faruk; Güney, İbrahim; Isac, Nicoleta; Khan, Asad ul Islam; Yönetim Bilimleri Fakültesi, İktisat Bölümü; Yönetim Bilimleri Fakültesi, İktisat BölümüThis paper evaluates the performance of eight tests with null hypothesis of cointegration on basis of probabilities of type I and II errors using Monte Carlo simulations. This study uses a variety of 132 different data generations covering three cases of deterministic part and four sample sizes. The three cases of deterministic part considered are: absence of both intercept and linear time trend, presence of only the intercept and presence of both the intercept and linear time trend. It is found that all of tests have either larger or smaller probabilities of type I error and concluded that tests face either problems of over rejection or under rejection, when asymptotic critical values are used. It is also concluded that use of simulated critical values leads to controlled probability of type I error. So, the use of asymptotic critical values may be avoided, and the use of simulated critical values is highly recommended. It is found and concluded that the simple LM test based on KPSS statistic performs better than rest for all specifications of deterministic part and sample sizes.Yayın Threat of intervention in cryptocurrency market: West side story of Bitcoin and Ripple(Bucharest University of Economic Studies, 2023) Aysan, Ahmet Faruk; Isac, Nicoleta; Drammeh, Ousman; Khan, Asad ul Islam; Özcan, Rasim; Yönetim Bilimleri Fakültesi, İktisat BölümüThis study examines the impact of intervention threats on the price and volume volatility of Bitcoin and XRP. Using the Threshold or GJR-GARCH model, we analyse the relationship between news shocks (representing intervention threats) and the volatilities of Bitcoin and XRP price and volume returns, based on data from January 2014 to April 2021. The results indicate a significant association between news shocks and Bitcoin's price volatility, suggesting that intervention-related news events have a notable impact. However, the relationship between news shocks and XRP's price volatility is insignificant. Notably, XRP's volume returns demonstrate a positive and significant relationship with news shocks, while Bitcoin's volume returns do not exhibit a significant relationship. Additionally, past shocks and conditional variance shocks significantly contribute to the volatility of today's price or volume returns. These findings suggest that Ripple (XRP) may benefit from the implicit threat of intervention, strategically managing its availability to control price surges.
