Article
Full-text available
The energy transition, a process in which fossil fuels are being replaced by cleaner sources of energy, comes with many challenges. The intrinsic uncertainty associated with renewable energy sources has led to a search for complementary technologies to tackle those issues. In recent years, the use of electric vehicles (EVs) has been studied as an a...
Article
Full-text available
Climate change and the transition to renewable energy sources have had a significant impact on wholesale electricity markets. This has led to renewed interest in the design of electricity markets and pricing rules for spot markets. It is well known that theoretical ideals such as Walrasian equilibria cannot be obtained because of the nonconvex natu...
Article
Full-text available
Europe’s clean energy transition is imperative to combat climate change and represents an economic opportunity to become independent of fossil fuels. As such, the energy transition has become one of the most important, but also one of the most challenging economic and societal projects today. Electricity systems of the past were characterized by pr...
Article
Social influence is ubiquitous in cultural markets and plays an important role in recommendations for books, songs, and news articles to name only a few. Yet social influence is often presented in a bad light, often because it supposedly increases market unpredictability. Here we study a model of trial-offer markets, in which participants try produ...
Preprint
Full-text available
We study the problem of pricing under a Multinomial Logit model where we incorporate network effects over the consumer's decisions. We analyse both cases, when sellers compete or collaborate. In particular, we pay special attention to the overall expected revenue and how the behaviour of the no purchase option is affected under variations of a netw...
Article
Full-text available
This paper considers trial-offer markets where consumer preferences are modelled by a multinomial logit with social influence and position bias. The social signal for a product is given by its current market share raised to power r (or, equivalently, the number of purchases raised to the power of r). The paper shows that, when r is strictly between...

Conference Paper
Full-text available
We study dynamic trial-offer markets, in which participants first try a product and later decide whether to purchase it or not. In these markets, social influence and position biases have a greater effect on the decisions taken in the sampling stage than those in the buying stage. We consider a myopic policy that maximizes the market efficiency for...
Article

This paper considers trial-offer and freemium markets where consumer preferences are modeled by a multinomial logic model with social influence and position bias. The social signal for a product i is its market share raised to some power r. The paper shows that, when 0 < r < 1 and a static position assignment (e.g., a quality ranking) is used, the...

Mathematical Engineering Thesis (In Spanish): The main goal of this thesis is to study a learning model in repeated games. Unlike other schemes studied in the literature , in this case a situation where players have very little information is studied, they can see only the received payment at each stage but without observing the strategies used by...

Question (1)
Question
I want to prove that certain function $F:\Delta\to\mathbb{R}$ is non-negative (or find some counterexample). Where $\Delta$ is the $n$ dimensional simplex.
The details are in the attached document, I include some ideas that i've been working on (I have been trying to prove that the function has a minimum in a point $x^*$, where $F(x^*)=0$).

Develop novel Bilevel Mixed-Integer Program (BiMIP) solution algorithms, including traditional analytical and machine learning-based algorithms.
Project
Some of the topics studied relate to allocation and pricing problems, with a particular focus on demand flexibility as a way to accommodate the uncertainty associated to (variable) renewable resources. We are therefore dedicated to elaborate appropriate market designs for the day-ahead electricity market, having for instance expressive bid languages that allow participants to communicate their constraints and flexibilities, effectively. This project is in collaboration with many different research institutions across Germany.
