We consider the optimal harvesting problem for a fish farmer in a model which accounts for stochastic prices featuring a Schwartz 97 two factor price dynamics. Unlike any other literature in this context, we take account of the existence of a newly established market in salmon futures, which...

The COVID-19 pandemic has caused a significant negative impact on the world economy and financial markets due to its global nature and severity. This paper aims to comprehensively investigate the dynamics of short-, medium- and long-term risk spillovers across the major financial markets in the...

This paper examines the driving effect of economic policy uncertainty on bank systemic risk with a distinction between systemic linkage and bank tail risk. Using bank-level data of 25 economies during the period 2010-2020, we find consistent and robust evidence that policy uncertainty is...

Using the popular Schwartz 97 two-factor approach, we study future contracts written on fresh farmed salmon, which have been actively traded at the Fish Pool Market in Norway since 2006. This approach features a stochastic convenience yield for the salmon spot price. We connect this approach...

To insure a proper and meaningful productivity assessment of DMUs with different production technologies, this article develops a difference-based profit metafrontier Luenberger productivity indicator. Adopting the proposed model, we empirically measure the profit inefficiency and examine the...

BackgroundAs a crucial component of solar radiation, the association between exposure to ultraviolet (UV) radiation and acne remains unclear.ObjectivesTo investigate the association of previous exposure to ultraviolet radiation at different wavelengths or doses with acne in college...

Herein, MOF-derived magnetic CoFe2O4 with oxygen vacancy was successfully synthesized to activate peroxymonosulfate for the effective degradation of emerging organic contaminants. The introduction of oxygen vacancy not only increased the specific surface area of CoFe2O4, but also reduce the...

This research develops a new group-based profit difference model for comparing profit performance at the group level with heterogeneous production technology and currencies. The proposed model can fully measure component effects that contribute to cross-group profit variation and also explicitly...
