Next generation entrepreneur: innovation strategy through Web 2.0 technologies in SMEs

This essay studies the diffusion/adoption of Web 2.0 technologies in small and medium sized enterprises (SMEs)’ innovation strategies and particularly in research, development, design and other innovation activities. It looks at the effects of these technologies on the evolution and the dynamics of firm's innovation capabilities and the implications of entrepreneurial turnover on the adoption of said technologies. The study is based on original fieldwork with some 130 SMEs. The author finds that a consistent share of SMEs is actively trying to fill the knowledge gap and integrate Web 2.0 technologies in their innovation strategies. SMEs are managing this integration by progressively adjusting their behaviour in reaction to the opportunities offered by the technology and balancing the dependence of the business from the web. Barriers to the adoption of such technologies are also discussed.     

Web2.0环境下网络效应对价值共创的影响机理研究

Web2.0环境下,众多网络平台注重用户参与、交流互动与开放共享,为生产者、消费者等多主体协同参与价值共创提供了条件。为了深入探究网络外部性效应对Web 2.0价值共创模式的影响,研究构建了考虑网络效应的网络平台双边用户参与价值共创的理论模型,模型均衡解表明,消费者参与Web2.0网络平台进行价值共创会增加产品或服务的附加价值,提升消费者满意度,提高消费者对产品或服务的认知价值,进而吸引更多消费者参与价值共创,而消费者数量的增加会进一步提高该服务的价值,并吸引更多商户参与,由此产生正向网络外部性效应。建立了分析消费者剩余的经济模型,剖析了Web2.0环境下消费者无法参与价值分配却仍愿意参与价值共创的内在驱动因素。     

The diffusion of mobile telephony in Italy and the UK: an empirical investigation

Since its appearance mobile telephony has shown a remarkably fast diffusion pattern in most advanced countries. This paper investigates technological and economic factors that have influenced the diffusion process of cellular phones, in particular the diffusion speed and the upper limit. The epidemic model widely used in diffusion studies is summarised and discussed highlighting the evolutionary disequilibrium nature of diffusion processes. Moreover, the econometric specification of some of the models distinguishes between long-run relationships and short-run adjustments to a continuously evolving pattern. We find that the new digital technology, which coincides with increased competition in both Italy and the UK, has made the process faster and increased the saturation level in Italy, but not in the UK; in Italy only the decreasing price of the handset has affected the diffusion process, whereas we find that, in addition to that, decreasing tariffs and increasing consumption expenditures have been significant in shaping the diffusion process of mobile telephony in the UK.     

The late take-off phenomenon in the diffusion of telecommunication services: network effect and the critical mass

Telecommunication services are distinctive in that their adoptions are influenced by network effect resulting in the late take-off phenomenon and the critical mass problem. In this paper we examined the late take-off phenomenon in the diffusion process of telecommunication services. We first compared the parameters of the diffusion process of consumer durables with those of fax services in the US and Korea. By analyzing the parameters of a new diffusion model based on the threshold model proposed by Markus, we found that the late take-off phenomenon resulted from the low heterogeneity of the threshold distribution for the potential adopters. A simulation approach was proposed for the theoretical implication of the critical mass problem in the start-up telecommunications services.     

Diffusion of organisational innovations: an empirical test of an analytical framework

Alänge, Jacobsson, and Jarnehammar (1998) presented an analytical framework for studying the diffusion of organisational innovations, based on the developments in literature on technical innovations and their diffusion. The aim of this paper is to examine the validity of the framework. Two exploratory case studies were carried out on the diffusion of the organisational innovation TQM. The case studies showed that the framework is a useful tool for studying the diffusion of organisational innovations. However, factors such as learning processes on a national and international level and the role of fads need further consideration. In addition, factors needed for a long-term commitment such as boards and owners and internal political and cultural systems need to be further investigated. The paper also presents a model for analysing the different phases in a diffusion process.     

Understanding mobile data services adoption: Demography, attitudes or needs?

Emerging technology enables industry to create products and services to fulfill previously unmet needs. Yet, the higher fixed costs and shrinking product life cycles associated with new digital technologies also generate business risk. While many companies engage in continuous innovation to maintain their market share, an innovation in itself does not guarantee success. Given these strategic shifts, traditional methods of segmentation are inadequate, especially in markets driven by flexible information and communication technologies (ICT). This study bridges this gap by examining existing innovation and market segmentation literature, proposing an integrative framework that incorporates knowledge from both, and validating this model through field research. Application of this integrative model can help service developers, facilitators and operators design, distribute and communicate new services to fulfill the needs of potential adopters.     

Does Web 2.0 utilisation lead to knowledge quality,improvisational creativity,compositional creativity,and innovation in small and medium-sized enterprises? A sense-making perspective

A few attempts were made to investigate how sense making is triggered through Web 2.0 utilisation and how it enables the accomplishment of key organisational outcomes. The objective of this research is to examine the structural relationship between Web 2.0 utilisation, knowledge quality (KQ) aspects, improvisational creativity, compositional creativity, and small and medium-sized enterprises (SMEs) innovativeness in an emerging market – Malaysia. Built upon sense-making theory, this study proposes that sense making is a progression of four formative constructs. Empirical analyses are based on a sample from SMEs’ top management (N?=?358, response rate?=?21%) using partial least squares approach. The findings indicate that Web 2.0 utilisation influences business entities’ sense-making activities in the way they realise the intrinsic value of knowledge and take action to apply the organisational knowledge. These sense-making activities are conducive to improvisational and compositional creativity of SMEs as well. Contributions, managerial implications, and limitations are discussed.     

The real exchange rate determination: An empirical investigation

This study examines the real exchange rate determination in Asian economies. The methods show that the real exchange rate and terms of trade can be jointly determined. Productivity differential, terms of trade, the real oil price, and reserve differential are found to be important in the real exchange rate determination in the long run. However, the significant impacts of those variables on the real exchange rate determination are different across economies. Moreover, the results of the generalised forecast error variance decompositions show that the important contributors of the real exchange rate are different across economies.     

The usage of VoIP services and other communication services: An empirical analysis of Italian consumers

This paper examines the early stages of VoIP usage by analyzing the relationship between the usage of VoIP services and other voice and non-voice communication services in Italy. In doing so, it aims at filling the gap in the empirical literature on the diffusion of VoIP among consumers and aims at investigating the relationship between VoIP adoption and the usage of telecom and Internet-related services. It relies upon a survey carried out among consumers in Italy in 2006. The use of VoIP is negatively associated with the usage of other voice communication services — mobile communications in particular, but shows some degree of complementarity with other non-voice (Internet-based) communication services, suggesting that familiarity with the web plays a significant and positive role in explaining the adoption of VoIP applications. Furthermore, individual users' technical skills, job position and communications' habits also matter in determining the adoption of VoIP.     

The size and development of the shadow economy: An empirical investigation from states of India

Using the state level data from India, this paper investigates the size of the hidden economy in Indian states over the period 1974/75 to 1995/96. Our analysis has shown that after liberalization of the Indian economy in 1991/92, the growth in the size of the hidden economy has decreased on an average. Our results show that the growth in the size of the hidden economy is approximately 4% less in scheduled election years than in all other years. We also demonstrate that the growth is significantly lower in those states where the coalition government is in power. An increased growth of newspapers and the literacy rates translate to cleaner governance, e.g. to fewer amounts of shadow economy activities in the economy.     

Culture and labour productivity: An empirical investigation

Culture is considered as one of the most powerful forces that shape human behaviour and thereby economic activity. This paper investigates the effects of culture on labour productivity and examines the cultural traits driving this relationship. Using panel data analysis, empirical evidence is provided covering a sample of 34 OECD countries over a wide period of three decades. Our empirical results suggest a significant positive relationship between the cultural background and labour productivity. The main channels of this positive impact are control and work ethic environment, while obedience has a negative impact on productivity. These findings are robust to a series of robustness checks, including alternative cultural measures, additional control variables, various country samples, and alternative specifications.     

The effect of government expenditure on the environment:An empirical investigation

This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980–2000. We estimate both the direct and indirect effects of government spending on pollution. The indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution. To take into account the dynamic nature and the potential endogeneity in the relationships examined, appropriate econometric methods are used. For SO₂, government spending is estimated to have a negative direct impact on per capita emissions, while the direct effect is insignificant on CO₂ pollution. The indirect effect on SO₂ is negative for low income levels and becomes positive as income increases, while it remains negative for CO₂ for the most part of the sample range. The resultant total effects follow the patterns of the indirect effects, which dominate their respective direct ones for each pollutant. Policy implications from the results vary depending on the income level of the considered countries.     

Determinants of terrorism in Pakistan: An empirical investigation

The purpose of this study is to analyze the determinants of terrorism in the context of Pakistan. The determinants of terrorism include various socio-economic variables like GDP per capita, unemployment, political rights, inflation, poverty, inequality and literacy level. A long-run relationship between the variables is analyzed by applying Johansen co-integration technique. The Error Correction Model (ECM) is applied to determine the stability of the long run relationship between terrorism and various variables and also to streamline the short-run and long run impacts of the variables on terrorism. In general, the results revealed that there exists a long run relationship between various social and economic variables and terrorism while the results of ECM revealed that about 89% convergence towards equilibrium takes place every year. Similarly, important results are obtained by short run and long run elasticities estimated under the Error Correction Model. Impulse response analysis reveals that the impacts of one standard deviation shock given to random disturbances on the systems of variables have mixed results. Some variables have increasing trend over the time period, some have decreasing trends, while some have fluctuating and cyclical trends.     

Firm heterogeneity and trade-induced layoffs: An empirical investigation

We use a novel data set with verified observations of trade-induced layoffs by U.S. firms to study the interaction between firm productivity and trade liberalization as key determinants of firm-level job destruction due to trade. We find that patterns of trade-induced layoffs are broadly consistent with the predictions for firm-level employment generated by the Melitz (2003) heterogeneous firms theory – the number of trade-induced layoffs increases with firm productivity for non-exporting firms but decreases with firm productivity for exporting firms. The fact that exporting firms incur trade-induced layoffs at all invites a refined interpretation of the theory. Our findings suggest that exporting firms may lay off some workers who work in production for their shrinking domestic segments, while also engaging in some within-firm reallocation of workers. We also find that, even after controlling for productivity and export status, larger firms lay off more workers due to trade competition.     

Banking integration in ASEAN-6: An empirical investigation

Banking integration is widely considered as the last stepping stone of economic integration, especially at the regional level. This paper aims to introduce extended measures of banking openness and the overall balanced degree of integration through capital flows. Using the quarterly data from the ASEAN-6 economies (Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) from 1996Q4 to 2016Q4, the obtained empirical results reveal that: (i) the degree of banking openness, which measures the total inflows and outflows divided by the total banking assets of the given country, remains low and even slightly decreases, despite the increasing cross-border banking and greater economic links among ASEAN-6; (ii) the overall degree of balance, which calculates the balance and the diversification of outward and inward integration, fluctuates over time but reaches the well-balanced level. Furthermore, the research highlights main drivers of the banking integration in this region, such as regulatory quality, bank size and the global credit risk. These findings have important policy implications for banking stability and integration in ASEAN-6.     

An empirical investigation of organizational memetic variation

The potential of a theory based on organizational memes in coevolution with the environment has been postulated, but remains empirically under-developed. This study explores whether understanding organizational memetic variation is empirically possible and, if so, whether it might, with further development, provide managers with early indications of a misalignment between organizational action (operationalized as memetic variation) and strategic intent—the amount of memetic variation needed to stay aligned with the competitive environment. A method for empirically identifying knowledge-based memes in everyday practice is developed. It stems from modern advances in genetics allowing micro-level changes in genes to be linked to macro-environmental dynamics. Using the concept that memetic variation is caused by everyday, uncontrollable uncertainties of interpretation, memetic variation is reduced to seven categorical types. A highly exploratory quasi-experimental design allows a preliminary comparison of a would-be innovative ‘Portfolio Management Committee’ with self-organizing Internet chat-room settings that are representational of open-source innovation. Results are consistent with predictions showing that higher levels of variation are seen in the latter, despite the former’s strategic intent of innovating to stay aligned with a dynamic environment. Further work is needed, however, to test reliability and validity.      

Household inventory behavior: An empirical investigation of grocery purchases

Theoretical studies have recently drawn attention to the significance of non-durable commodity holdings by households. The present paper is an effort to find empirical evidence that household inventory behavior has definable properties. A large set of grocery purchase data, the Chicago Tribune Consumer Panel, is investigated. On the basis of the analysis it is suggested that grocery shopping behavior broadly conforms to that anticipated by inventory theory and that the rate of discount applied on these holdings varies negatively with income across households.
