Paris s'éveille
Hype, the world’s largest hydrogen taxi operator, is to cease operating its fleet of hydrogen taxis in the Paris area
When the reality of #hydrogen costs hits home (and you still don't want to believe it)

'A form of oligopoly' | World’s largest hydrogen taxi operator hurls accusations at supply giants as it quits H2 in Paris
Hype argues that Air Liquide and TotalEnergies have presided over doubling of H2 prices in four years — which it says is blocking a credible path to green hydrogen use

Predictive Performance of LSTM Networks on Sectoral Stocks in an Emerging Market: A Case Study of the Pakistan Stock Exchange
The application of deep learning models for stock price forecasting in emerging markets remains underexplored despite their potential to capture complex temporal dependencies. This study develops and evaluates a Long Short-Term Memory (LSTM) network model for predicting the closing prices of ten major stocks across diverse sectors of the Pakistan Stock Exchange (PSX). Utilizing historical OHLCV data and an extensive set of engineered technical indicators, we trained and validated the model on a…

Noen ganger er jeg helt enig med min bror:

Hans Petter Graver: – Trekk Oljefondet ut av Israel
Han var med på å lage Oljefondets etiske retningslinjer. Nå ber han regjeringen ta grep og få Oljefondet ut av Israel.

Two-Sided Market Power in Firm-to-Firm Trade
This paper develops a theory of bargaining in firm-to-firm trade with two-sided market power. The framework accommodates flexible market structures, yielding analytical expressions for pair-specific markups and pass-through elasticities. In U.S. import data, we estimate strong importer bargaining power and an upward-sloping export supply curve, consistent with oligopsony power. Pass-through of the 2018 tariffs in firm-to-firm relationships is incomplete, in contrast to product-level studies, pr…

OleSpeech-IV: A Large-Scale Multispeaker and Multilingual Conversational Speech Dataset with Diverse Topics
OleSpeech-IV dataset is a large-scale multispeaker and multilingual conversational speech dataset with diverse topics. The audio content comes from publicly-available English podcasts, talk shows, teleconferences, and other conversations. Speaker names, turns, and transcripts are human-sourced and refined by a proprietary pipeline, while additional information such as timestamps and confidence scores is derived from the pipeline. The IV denotes its position as Tier IV in the Olewave dataset ser…

Att "The Anti-Autocracy Handbook - A Scholars’ Guide to Navigating Democratic Backsliding" ens existerar är i sig självt olycksbådande, och läsningen fångar mig. Nedmonteringen av USA:s demokratiska institutioner går fort och långsamt på en och samma gång.
Jag reflekterar på bloggen över konsekvenserna av den svåra och problematiska utveckling som syns i USA, inte minst för forskare och akademin, och ger några tankar om vad vi behöver göra.

Autocratic strategies in Cournot oligopoly game
An oligopoly is a market in which the price of a goods is controlled by a few firms. Cournot introduced the simplest game-theoretic model of oligopoly, where profit-maximizing behavior of each firm results in market failure. Furthermore, when the Cournot oligopoly game is infinitely repeated, firms can tacitly collude to monopolize the market. Such tacit collusion is realized by the same mechanism as direct reciprocity in the repeated prisoner's dilemma game, where mutual cooperation can be rea…

Eine ausgezeichnete WISO-Reportage über das Preischaos an deutschen öffentlichen Ladestationen. Ein drohendes Oligopol schwächt den Wettbewerb. Der BDEW verteidigt natürlich die etablierten Unternehmen und auch das BMWE hält den Markt noch für jung.
