Cumulative prospect theory and mean-variance analysis: a rigorous comparison
We propose a numerical optimization approach that can be used to solve portfolio selection problems including several assets and involving objective functions from cumulative prospect theory (CPT). Implementing the suggested algorithm, we compare asset allocations that are derived for CPT based on two different methods: maximizing CPT along the mean–variance efficient frontier so...

This paper studies whether the use of a competitive pricing mechanism reduces such wasteful activities. We report data from a laboratory experiment where a powerful buyer can trade with one of two sellers—an environment that can lead to very low prices for the sellers. We find...

The Code is the Model
Conventionally, agent-based models are specified in a combination of natural language and mathematical terms, and their implementation seen as an afterthought. I challenge this view and argue that it is the source code that represents the model best, with natural language and mathematical descriptions serving as documentation. This modeling paradigm is inspired by agile software...

This applies in particular if local subsidiaries of multinational enterprises (MNEs) are committed to ‘principled embeddedness’ meaning that they are prepared to integrate parts of the local economy into global value chains by enabling them to comply with the...

Positive Sustainability Effects Resulting from Embeddedness: Evidence from Syngenta’s potato business in Kenya and Colombia
A variety of studies assess the impact of multinational enterprises (MNE) in developing countries. They mainly focus on the negative externalities of these companies. Therefore, this study focuses on the positive effects emanating from the presence of MNEs in developing countries. It is hypothesised that positive externalities resulting from MNEs have their source in the local...

Steerable wavelet machines (SWM): : learning moving frames
We present texture operators encoding class-specific local organizations of image directions (LOIDs) in a rotation-invariant fashion. The LOIDs are key for visual understanding, and are at the origin of the success of the popular approaches, such as local binary patterns (LBPs) and the scale-invariant feature transform (SIFT). Whereas, LBPs and SIFT yield hand-crafted image...

Under-connected and over-connected networks: the role of externalities in strategic network formation
Since the seminal contribution of Jackson and Wolinsky (J Econ Theory 71(1):44–74, 1996) it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has not been studied systematically are the sources of inefficiency. We approach this omission by analyzing the role of positive...
