The innovation value chain (IVC) divides the innovation process into three separate links or activities: knowledge gathering, knowledge transformation and knowledge exploitation. Here, we report a comparative panel data analysis of the IVC in Ireland and Switzerland. Both economies are small, very open and depend significantly on innovation to maintain competitive advantage. In recent years, ho...

The paper analyzes how international outsourcing affected individual employment security. The analysis is carried out at the micro-level, combining monthly spell data from household panel data and industry-level outsourcing measures. By utilizing micro-level data, problems such as aggregation and potential endogeneity bias, as well as crude skill approximations that regularly hamper industry le...

This study estimates agency’s impact on sugar plantation productivity using a unique early 19th century panel data set from St. Vincent and the Grenadines. Results of fixed effects models, combined with a qualitative and quantitative analysis of potential endogeneity of the agency variable, provide no evidence that estates managed by agents were less productive than those managed by their owner...

This paper provides an overview of recent econometric advances on testing of functional form with semiparametric methods and their application to the estimation of the environmental Kuznets curve (EKC). The EKC in environmental economics is estimated using panel data models and provides a fertile ground for the adoption of recent panel data developments. The paper provides a discussion of recen...

An estimation framework and a user-friendly software implementation are described for maximum likelihood estimation of panel data models with random effects, a spatially lagged dependent variable and spatially and serially correlated errors. This specification extends static panel data models in the direction of serial error correlation, allowing richer modelling possibilities and more thorough...

This introduction to the plm package is a slightly modified version of Croissant and Millo (2008), published in the Journal of Statistical Software. Panel data econometrics is obviously one of the main fields in the profession, but most of the models used are difficult to estimate with R. plm is a package for R which intends to make the estimation of linear panel models straightforward. plm pro...

W quantify how user mobile Internet usage relates to unique characteristics of the mobile Internet. In particular, we focus on examining how the mobile-phone-based content generation behavior of users relates to content usage behavior. The key objective is to analyze whether there is a positive or negative interdependence between the two activities. We use a unique panel data set that consists ...

This paper reviews some of the econometrics problems faced when estimating a rational addiction model of Becker and Murphy (1988) using panel data. This is illustrated with three empirical applications. The …rst application looks at cigarette consumption using macro panel data on American states over time (see Baltagi and Gri¢ n (2001)). The second application looks at liquor consumption using ...

Abstract The work at hand presents a new extensive panel dataset for energy economics, econometrics and policy. referred is made of 5000 observations circa, including 6 economics variables the majority world’s countries (n = 136), extended years (2009–2014). Data can be used diverse studies, especially socioeconomic environmental aspects innovation efficiency investigations. analysed data explo...
