    Abstract: The policy guidance lays out the policy responses that need to be in place to ensure that consumers engaging in mobile commerce transactions are adequately informed, and are protected against security or privacy risks.

    Abstract: The paper offers an exploratory empirical analysis of the impact on consumers’ welfare of the reforms of the gas industry in EU-15 area. After considering the key features of the natural gas industry and of its reform in selected countries, we study the relationship between regulatory reform indicators and price dynamics by means of panel data techniques. We find that none of the relationships between price dynamics and regulatory reform indicators is robust to different econometric specifications. Our findings suggest that until now there is limited evidence of beneficial effects of a standard package gas industry reforms for the European consumers. Country specific factors and price inertia seem to be more important than the reforms as determinants of consumers’ prices.
    Keywords: Natural gas industry, privatization, liberalization, regulatory reform.

    Abstract: The product lifecycle model can be understood as a three-stage model of technological development associated with a particular product technology. In the explorative stage many different designs are developed, in the development stage products become standardized into a dominant design, and in the mature stage only incremental changes occur within the dominant design. Although the product lifecycle model is widely accepted and often applied in empirical research, innovation scholars have failed to develop systematic theoretical models that explain the different stages of technological development along the lifecycle. In this study, an attempt is made to contribute to product lifecycle theory by developing a theoretical model based on percolation dynamics. The model combines the concept of increasing returns to adoption with information diffusion among consumers within social networks. The main contribution of the model is that it replicates the three stages of the product lifecycle as an outcome of a single elementary process. The model also replicates the S-shaped diffusion curve and the occurrence of an industry shakeout.
    Keywords: mathematical models, percolation model, diffusion, social networks, product lifecycle, dominant design
