Purpose – The purpose of this paper is to examine contagion among the major world markets during the last 25 years and propose a new way to analyze contagion with wavelet methods. Design/methodology/approach – The analysis uses a novel way to study contagion using wavelet methods. The...

Purpose – The purpose of this paper is to investigate the variables affecting firm profitability, applying the seemingly unrelated regression method to a large sample of approximately 87,000 observations covering 12,530 non-financial micro firms operating in four industry sectors, from 2006 to...

For decades, financial institutions have been very motivated in creating structured high-yield financial products, especially in the economic environment of lower interest rates. Reverse convertible notes (RCNs) are the type of financial instruments, which in recent years first in Europe and...

Purpose – This paper proposes a simple technique for assessing the effect of gear transmission errors in a six‐axis industrial serial robot, as these errors can vitally affect the industrial robot's positioning accuracy. Design/methodology/approach – The experimental procedure is developed...

This paper considers the pricing of European call options written on pure endowment and deferred life annuity contracts, also known as guaranteed annuity options. These contracts provide a guaranteed value at the maturity of the option. The contract valuation is dependent on the stochastic...

This article proposes a nonparametric test of monotonicity for conditional distributions and its moments. Unlike previous proposals, our method does not require smooth estimation of the derivatives of nonparametric curves. Distinguishing features of our approach are that critical values are...
