The stability of the labour share income is a fundamental feature macroeconomic models, with broad implications for shape production function, inequality, and dynamics. However, empirically, this has been slowly declining in many countries several decades, though its causes are subject much debate. This paper analyses drivers developments Europe at sectoral level. We begin simple shift-share an...

Secret sharing schemes for classical secrets can be classified into secret and quantum schemes. Classical has been known to able distribute some shares before a given secret. On the other hand, mechanics extends capabilities of beyond those sharing. We propose with in designing access structures more flexibly realizing higher efficiency sharing, that

Proactive Secret Sharing (PSS) scheme is a method to periodically renew n secret shares in a (k, n) threshold-based Secret Sharing Scheme (SSS) without modifying the secret, or reconstructing the secret to reproduce new shares. Traditionally, PSS schemes are developed for the Shamir’s SSS which is a single SSS. Bai (2006) developed a multiple-secret sharing scheme using matrix projection. This ...
