Does Transport Behavior Influence Preferences for Elektromobility? An Analysis Based on Person- and Alternative-Specific Error Components

The interconnection among different choices by the same decision-maker is fairly well established in the literature. Along this line, this paper aims to identify how preferences for electromobility are affected by mode choices for regular trips. With this purpose in mind, a framework based on person- and alternative-specific error components (covariances) is proposed. The method aims to include individual-specific ...

About the Categorization of Latent Variables in Hybrid Choice Models

Although hybrid choice models are fairly popular nowadays, the way in which different types of latent variables are considered into the utility function has not been extensively analysed. Latent variables accounting for attitudes resemble socioeconomic characteristics and, therefore, systematic taste variations and categorizations of the latent variables should be considered. Nevertheless, categorizing ...

Analyzing the Continuity of Attitudinal and Perceptional Indicators in Hybrid Choice Models

This paper addresses the continuity of attitudinal and perceptual indicators in hybrid discrete choice models and the main objective of this work is to compare the consequences of treating the indicators as continuous or ordinal outcomes, given different assumptions about the way in which these are stated. Based on tradition and for computational reasons, such indicators are predominantly treated as ...

Climate Negotiations: What Can Be Expected from the Climate Summit in Paris?

Shortly before the upcoming UN climate summit, Angela Merkel wrote in a German newspaper: “With good reason, it is expected from governments and politicians, that they do not longer close their eyes to the pressing scientific results that climate protection requires rapid and vigorous action.” She further calls for a clear negotiation outcome: “The greenhouse gas emissions do not only have to be stabilized, ...

Measuring Productivity When Technologies Are Heterogeneous: A Semi-Parametric Approach for Electricity Generation

While productivity growth in electricity generation is associated with multiple positive effects from an economic and environmental perspective, measuring it is challenging. This paper proposes a framework to estimate and decompose productivity growth for a sector characterized by multiple technologies. Using a metafrontier Malmquist decomposition and frontier estimation based on stochastic non-smooth ...
