"New product growth models - also called innovation diffusion models - are used to describe and forecast the evolution in time of sales of new products. Commercial products are characterized by a finite life cycle, which follows a nonlinear path, namely birth, growth, maturity, and decline. Previously, traditional time series frameworks such as ARIMA models have been used, however, they do not prove a satisfactory choice. A growing need for quantitative marketing in today's market is driving the development of new product diffusion models to determine the life cycle of a new product. The statistical techniques involved in new model estimations combine time series analysis with nonlinear regression techniques, which this book shall explore. Innovation Diffusion Models: Theory and Practice fully assesses the main mathematical features of the models, discussing the meaning of the parameters from the marketing point of view with several real-data examples; presents and discuss the statistical aspects involved in model estimation and selection; presents and discusses forecasting and explanatory ability of the proposed models with real-data applications in several industrial and commercial sector and proposes new ideas for future achievements in research and commercial practice."--

This study explored the size and potential of green employment for circular economy (CE) in small and medium enterprises (SMEs) in the European Union, and investigated the role of green jobs and skills for the implementation of CE practices. The data were collected in a Eurobarometer survey, and refer to resource efficiency, green markets, and CE procedures. Lack of environmental expertise is one of the factors that might be perceived as an obstacle when trying to implement resource-efficiency actions. Previous research has shown that, although resource-efficiency practices are adopted by firms in all European countries, there are differences both within and between countries. The analysis of the determinants of green behavior by European SMEs was completed by a study of heterogeneity across firms and within countries with a multilevel latent class model, a hierarchical clustering method. A general important observation is that having no workers dedicated to green jobs is strongly correlated to the probability of adopting resource-efficiency practices, while perceiving the need of extra environmental skills has a positive effect on the intention to implement actions in the future. Other characteristics of the firms play a significant impact on resource efficiency: in general, older and bigger firms, with larger yearly turnover, are more prone to implement actions.
