Reducing waste and ecological impacts through a sustainable and efficient management of perishable food based on the Monte Carlo simulation

2019

Abstract In today’s competitive global market it is mandatory to improve warehousing operations integrating economic, environmental and social aspects. The recent advancement in monitoring technologies can greatly improve the performance of the food supply chain reducing product loss. In particular, in the perishable food supply chain, initially inventory operations are critical because they manage the material flows in very variable conditions. The deterioration level of the products as well as the market demand are the main factors that can influence warehouse strategy. This research aims to consider the application of sustainability principles in the context of warehouse storage, evaluat…

Modeling the natural gas supply chain for sustainable growth policy

2020

Abstract Natural gas has been used globally as a transitional fuel for supporting a green-energy-supply strategy, which has been questioned for the intermittence and lack of reliability of renewables. This paper proposes a System Dynamics model for assessing alternative security of supply policy along the natural gas value chain. The model incorporates demand, transport, production and reserves of natural gas variables according to a systemic perspective. It also includes a module for evaluating the effect of natural gas price on the demand and supply levels, respectively. Alternative supply policies are evaluated under different scenarios. The chosen case-study focuses on the Colombian nat…

An exploration of digital ride-hailing multisided platforms' market dynamics: empirical evidence from the Uber case study

2020

PurposeThe purpose of this paper is to experiment a dynamic performance management (DPM) approach to explore and assess the business dynamics of digital ride-hailing platforms with a focus on both supply and demand sides, and related interplays.Design/methodology/approachThe research adopts the DPM framework supported by simulation-based experimentations for developing a systemic case interpretation of Uber Inc. and its specific business complexity.FindingsThe emerging scenario analysis reveals that changes in the commission percentage for drivers and cutting prices for customers (car hailers) by competitors have significant impacts on the car-hailing industry.Originality/valueDPM and assoc…

Housing market shocks in italy: A GVAR approach

2020

Abstract In this paper, we use a Global Vector Autoregression (GVAR) model to assess the spatio-temporal mechanism of house price spillovers, also known as “ripple effect”, among 93 Italian provincial housing markets, over the period 2004 − 2016 . In order to better capture the local housing market dynamics, we use data not only on house prices but also on transaction volumes. In particular, we focus on estimating, to what extent, exogenous shocks, interpreted as negative housing demand shocks, arising from 10 Italian regional capitals, impact on their house prices and sales and how these shocks spill over to neighbours housing markets. The negative housing market demand shock hitting the G…

Consumers of flowers and ornamental plants: an eploratory survey in the Italian «Mezzogiorno» regions

2010

This paper aims to provide further knowledge of purchase and consumption behaviours with regard to flowers and ornamental plants in the regions of Italian «Mezzogiorno», as an acknowledgement of the centrality of final demand in the chain process. The knowledge of consumption process is fundamental either to the firm – in order to improve commercial strategies – or to competition authorities – with the purpose of implementing more effective policies. From the analysis carried out it emerges that flowers and ornamental plants consumption in the «Mezzogiorno» regions is characterised by a high penetration index and – just with regard to some commodities – by a low purchase frequency. Purchase…

Pricing of electricity futures based on locational price differences : The case of Finland

2018

We find that the pricing of Finnish electricity market futures has been inefficient during the latest 10 years, when the trading volumes of Electricity Price Area Differentials (EPADs) have more than doubled. Even though the calculated futures premium on EPADs is related to some risk measures and the variables capturing the demand and supply conditions in the spot electricity markets, there has been a significant positive excess futures premium in the Finnish market, and financial market participants should have been able to utilize this also in economic terms. This finding is new and relevant for the participants of the Nordic electricity markets also in the future, because both the specul…

Autonomous Operation of Stationary Battery Energy Storage Systems—Optimal Storage Design and Economic Potential

2021

Global warming requires a changeover from fossil fuel based to renewable energy sources on the electrical supply side and electrification of the demand side. Due to the transient nature of renewables and fluctuating demand, buffer capacities are necessary to compensate for supply/demand imbalances. Battery energy storage systems are promising. However, the initial costs are high. Repurposing electric vehicle batteries can reduce initial costs. Further, storage design optimization could significantly improve costs. Therefore, a battery control algorithm was developed, and a simulation study was performed to identify the optimal storage design and its economic potential. The algorithm used is…

Forecast Output Coincidence and Biproportion: Two Criteria to Determine the Orientation of an Economy. Comparison for France (1980-1997)

2002

International audience; The method of forecast output coincidence used to determine if sectors are demand-sided or supply-sided in an input-output framework mixes two effects, the structural effect (choosing between demand and supply side models) and the effect of an exogenous factor (final demand or added-value). The note recalls that another method is possible, the comparison of the stability of technical and allocation coefficients, generalized by the biproportional filter: if for a sector, after biproportional filtering, column coefficients are more stable than row coefficients, then this sector is declared as not supply-sided (but one cannot decide that it is demand-sided anyway), and …

Organised Crime and the Economy: a Framework for Policy Prescriptions

2014

In this paper we discuss policies to combat organised crime from the perspective of economic analysis. We introduce concepts such as supply and demand for Mafia and the implied notion of equilibrium to build a framework to classify the contexts in which organised crime interferes with the economy. We then use this framework to discuss policy interventions, distinguishing between policies implemented by the State and mobilisation of civil society. We show that using the economic approach helps understand the aspect of persistence of criminal organisations and identify vicious circles of different nature. The broad spectrum of State policies identified includes norms on competition, on the ef…

Market Must Be Defended: The Role of Counter-Espionage Policy in Maximizing Domestic Market Welfare

2020

Countering economic espionage is becoming one of the priorities of the governments of advanced economies. The present paper takes a step forward in the theoretical analysis of the interaction between economic espionage and counter-espionage by focusing on the case of a market opened to international trade. This analysis represents a first approximation to an inquiry into the rationale for the influence of the market level of competition on the dynamics of such interaction. The results suggest that this influence is complex in the case of the effort exerted in economic espionage and the characteristics of market demand play an important role in it. In the case of the counter-espionage policy…
