Counterparty risk valuation for Energy-Commodities swaps: Impact of volatilities and correlation [PDF]

arXiv, 2009
It is commonly accepted that Commodities futures and forward prices, in principle, agree under some simplifying assumptions. One of the most relevant assumptions is the absence of counterparty risk. Indeed, due to margining, futures have practically no counterparty risk.

Aluminum Scandium Nitride as a Functional Material at 1000 °C

Advanced Electronic Materials, EarlyView.
Aluminum scandium nitride (AlScN) exhibits remarkable ferroelectric, piezoelectric, and dielectric stability at extreme temperatures. This study demonstrates the robust performance of TaSi2/AlScN/TaSi2 capacitors up to 1000 °C, revealing a substantial increase in piezoelectricity and a marked reduction in coercive field.

Stringency and dissimilarity of Maximum Residue Levels affect bilateral agri‐food trade stability

Applied Economic Perspectives and Policy, EarlyView.
Abstract Food standards are rising in both prevalence and stringency. They protect consumers and may enhance demand stability but also pose compliance challenges to producers, with ambiguous effects on the stability of trade relationships. We analyze the impact of importers' Maximum Residue Levels (MRLs) along with bilateral MRL dissimilarity between ...
