Publikation Electricity trading with derivative instruments: Speculation, hedging, or speculative hedging?(Springer, 2024) Härri, Matthias; Hüttche, TobiasThe physical nature of electricity makes it difficult to store, which means that current demand must always match current production. This requires both flexible and internationally interconnected generation capacity and appropriate hedging strategies. Electricity is typically traded ‘forward’, i.e., future energy volumes and prices are hedged in advance with derivative instruments to minimize price risks. In times of crisis, when energy prices can be highly volatile, such instruments can also be used for speculative purposes. However, hedging and speculative positions can trigger margin calls on derivatives exchanges or increased collateral requirements in the over-the-counter (OTC) market. The causes, interrelationships and possible consequences of such margin calls on the financial situation of buyers and sellers of electricity (e.g., on balance sheet liquidity) are discussed. Paradoxically, the use of hedging instruments to protect against price volatility, together with prudential accounting standards, has led to financial problems for many electricity producers during the market turmoil of 2022, and to governmental bail outs. Whether the problems of large energy companies in Switzerland are due solely to hedging motives or to speculative proprietary trading is difficult for outsiders to judge.04A - Beitrag SammelbandPublikation Discounted or disrupted cash flow: impact of digitisation on company valuation(2019) Härri, Matthias; Hüttche, Tobias; Kustner, ClemensThis paper discusses the impact of digitisation on Business Valuation. In order to become and remain "digital", investments are necessary whose return on investment (ROI) often remains vague. This uncertainty is contradictory for a valuation that rely on predictable cash flows, fixed capital structures and the steady state. However, digitisation does not make a company valuation impossible, but traditional approaches must be reconsidered. First and above the valuation objects – the companies – will change: Their value drivers are more and more intangible if not invisible and the business models become finite. The valuation process will change: Predictive Analysis and Planning allow valuations in real time. Thus, the values and prices will vary more than we have seen in the past. After all and at the moment, man is still needed. There are some bottlenecks, where the human brain still beats robots and algorithms, at least when it comes to cost.04B - Beitrag KonferenzschriftPublikation Sovereign risk and the pricing of corporate credit default swaps(Infopro Digital Risk Limited, 20.03.2015) Härri, Matthias; Morkoetter, Stefan; Westerfeld, SimoneInvestigation about the impact of sovereign risk on the pricing of corporate credit risk.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Auf Kapitalmarktdaten basierende Insolvenzprognoseverfahren und Ratingmodelle(2008) Härri, Matthias99 - Sonstiges
