IMPROVEMENT OF STOCHASTIC MODELLING SKILLS FOR A SUSTAINABLE EDUCATION IN ENGINEERING [PDF]

Journal of Sustainable Energy
Deterministic 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 ...

Comparing alternatives to the fixed degree sequence model for extracting the backbone of bipartite projections

Scientific Reports, 2021
Projections of bipartite or two-mode networks capture co-occurrences, and are used in diverse fields (e.g., ecology, economics, bibliometrics, politics) to represent unipartite networks.

Stochastic effects in a discretized kinetic model of economic exchange [PDF]

Physica A: Statistical Mechanics and its Applications, 2017
Linear stochastic models and discretized kinetic theory are two complementary analytical techniques used for the investigation of complex systems of economic interactions. The former employ Langevin equations, with an emphasis on stock trade; the latter is based on systems of ordinary differential equations and is better suited for the description of ...

Deforestation and Efficiency: Insights From Forest Transition in the Brazilian Cerrado

Agribusiness, EarlyView.
ABSTRACT This paper estimates technical efficiency (TE) and environmental efficiency (EE) of agricultural production at the municipal level of the Brazilian Cerrado in 2006 and 2017, and investigates their underlying mechanisms in relation to forest transition theory.

The Identification and Economic Content of Ordered Choice Models with Stochastic Thresholds [PDF]

International Economic Review, 2007
This article extends the widely used ordered choice model by introducing stochastic thresholds and interval‐specific outcomes. The model can be interpreted as a generalization of the GAFT (MPH) framework for discrete duration data that jointly models durations and outcomes associated with different stopping times.

Livelihood Diversification as an Adaptation Strategy to Climate Change and Household Food Security of Livestock Holders in Pakistan

Agribusiness, EarlyView.
ABSTRACT Rural farm households continue to face significant risks from climate change, resulting in many of them diversifying their livelihood sources into other income‐generating activities to increase their incomes and improve food and nutrition security. In this study, we examine the drivers and impact of farm households' participation in livelihood

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.
