Bidirectional transformation (bx) approaches provide a systematic way of specifying, restoring, and maintaining the consistency of related models. The current diversity of bx approaches is certainly beneficial, but it also poses challenges, especially when it comes to comparing the different approaches and corresponding bx tools that implement them. Although a benchmark for bx (referred to as a...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood1, a rigorous analysis of investment incentives is still missing. Existing models, as the peak-load-pricing approach, analyze welfare optimal investment and find that optimal ...

Museum exhibits offer particular challenges for the design of interactive installations, as visitors usually cannot directly interact with artefacts. This paper presents a depth-sensor based system for interaction via pointing gestures that we developed for an interactive museum installation (IMI), permanently installed in a showcase of the grave of a Germanic princess. Users interact by walkin...

Enterprises continuously seek decision support tools that can help automate and codify business decisions. This is particularly true in the business of consumer electronics manufacturing where components are often interchangeable and several manufacturers can supply the same component over the life of a product. In this kind of dynamic environment, businesses are faced with the choice of signin...

This paper studies asymmetric price responses of individual firms, via daily retail prices of almost all gasoline stations in the Netherlands and suggested prices of the five largest oil companies over more than two years. I find that 38% of the stations respond asymmetrically to changes in the spot market price. Hence, asymmetric pricing is not a feature of the market as a whole, but of indivi...

In this paper we consider several parametric assumptions for the instantaneous covariance structure of the Libor market model. We examine the impact of each different parameterization on the evolution of the term structure of volatilities in time, on terminal correlations and on the joint calibration to the caps and swaptions markets. We present a number of cases of calibration in the Euro mark...

Chapter 1 introduced the foundations for the neoliberal interpretation of international institutions’ advocacy of liberalized trade. A critical assumption behind the neoliberal perspective is that free markets are in the collective interest – that is, that liberalized trade maximizes the gains to world as a whole, without regard to how those gains might be distributed. The economic theory under...

Microstructure models of foreign exchange markets emphasize two different channels of pressure in pricing dynamics; these are inventory and asymmetric information effects. Past empirical studies for foreign exchange markets have found evidence supporting the existence of both effects in the Dollar/DM market. This paper tests for the presence of within sample variation in the intensity of these ...
