Economic and environmental efficiency in Europe: Evidence from a new stochastic frontier model [PDF]
2015 12th International Conference on the European Energy Market (EEM), 2015 This study aims to evaluate the resource and environment efficiency problem of European countries. We specify a new stochastic frontier model where Gross Domestic Product (GDP) is considered as the desirable output and Greenhouse Gases (GHG) emissions as the undesirable output. Capital, Labour, Fossil fuels and Renewable Energy consumption are regarded

The excess volatility puzzle explained by financial noise amplification from endogenous feedbacks
Scientific Reports, 2022 The arguably most important paradox of financial economics—the excess volatility puzzle—first identified by Robert Shiller in 1981 states that asset prices fluctuate much more than information about their fundamental value.

IMPROVEMENT OF STOCHASTIC MODELLING SKILLS FOR A SUSTAINABLE EDUCATION IN ENGINEERING [PDF]
Journal of Sustainable EnergyDeterministic and stochastic models play an important role in engineering, economics, and the natural sciences. Despite this, the development of stochastic modelling skills in engineering students is less emphasized, and this part of modelling knowledge ...

On one-dimensional stochastic control problems: applications to investment models [PDF]
, 2008 The paper provides a systematic way for finding a partial differential equation that characterize directly the optimal control, in the framework of one?dimensional stochastic control problems of Mayer, with no constraints on the controls.

No Arbitrage in Continuous Financial Markets
, 2020 We derive integral tests for the existence and absence of arbitrage in a financial market with one risky asset which is either modeled as stochastic exponential of an Ito process or a positive diffusion with Markov switching.
