E-Government's Role in Shifting the Paradigm of Performance in the Public Sector

2015

The emergence of e-government changed the world of the Public Administration (PA) and the discipline of Public Management dramatically. Through the presentation of a case- study of the municipality of Palermo, this article attempts to discuss the renewed need for assessing performance of e-government services in a local government and to disclose the main critical issues in accomplishing this evaluation. Palermo is experiencing the implementation of a second- generation e-government project that is embodied in the realization of a web portal. The conceptualization of a framework to assess the performance of the digital services appears to be crucial in order to improve the system and to avo…

An optimized system dynamics approach for a hotel chain management

2009

The proposed model consists of an integrated system dynamics-data envelopment analysis approach to value, in a dynamic framework, the effects over time of the policies implemented according to the relative efficiency analysis. Rooms’ price and competing facilities (the hedonics) are the decision variables to move in order to push the hotels towards a higher relative efficiency at the end of the observation periods. In fact, in competitive markets as tourism, hotels compete for money offering differentiated quality. Moreover, according to the microeconomic theory, a producer of differentiated goods is not a price taker but a price maker. Therefore, we assume that the decision maker of the ho…

Impact of COVID-19 on the travel and tourism industry.

2021

Abstract Our paper is among the first to measure the potential effects of the COVID-19 pandemic on the tourism industry. Using panel structural vector auto-regression (PSVAR) (Pedroni, 2013) on data from 1995 to 2019 in 185 countries and system dynamic modeling (real-time data parameters connected to COVID-19), we estimate the impact of the pandemic crisis on the tourism industry worldwide. Past pandemic crises operated mostly through idiosyncratic shocks' channels, exposing domestic tourism sectors to large adverse shocks. Once domestic shocks perished (zero infection cases), inbound arrivals revived immediately. The COVID-19 pandemic, however, is different; and recovery of the tourism ind…

Smart grid integrated green data centres as ancillary service providers

2015

In this paper a review of Green Data Centres facilities to support smart grids operation is proposed. The paper describes the ancillary services a Green Data Centre can provide both in terms of spinning reserve provision and different regulation services. In the application section, a real electrical grid hosting a data centre is considered. The infrastructure is owned by Engineering S.p.A. and is installed in northern Italy. The system has been considered as connected to the MV distribution grid in presence of other renewable energy sources. The impact of possible power management operations over the considered data centre has been studied by means of a simulation software and the spinning…

Using Group Model Building and System Dynamics Modeling in Health Care Quality Assessment

Introduction & Research Aim Drawing from previous research on performance management, arguing that measurement systems in the public sector sometimes lead to harmful outcomes (Bianchi, 2010, 2015; Bivona & Montemaggiore, 2010), the purpose of this study is to assess the long-term dynamic impact of “ESY-net” (i.e. the Greek public hospitals' national performance measurement system) on the quality of healthcare services. Methods As hospital quality is a quite broad and abstract concept, perceived differently by different stakeholders, we will take a systemic view (Meadows, 2008; Sterman, 1994) and use Group Model Building (GMB) (De Gooyert, 2016, 2018; De Gooyert, Honingh, & Van G…

Exploring the relationships between tangible and intangible resources in a learning alliance dynamics: comment on the paper by Kapmeier

2008

Kapmeier (2008) focuses his research on common learning and firms’ opportunistic behaviour in learning alliances. A strategic alliance, as clearly stated by Gulati (1998, p. 293) is a voluntary arrangement between firms to exchange and share knowledge as well as resources with the intent of developing processes, products or services. This is a relevant topic not only for those firms that operate in industries characterized typically by high RD Larsson et al., 1998). Furthermore, this literature essentially takes a static view and it often neglects the postformation dynamics of alliances (Koza and Lewin, 2000; Das and Teng, 2001). Some key questions not yet profoundly investigated are: how c…

Dealing with Multi-Level Governance and Wicked Problems in Urban Transportation Systems: The Case of Palermo Municipality

2015

Italian New Public Management (NPM) has been mainly characterized by a political orientation toward power decentralization to local governments and privatization of public companies. Nowadays, local utilities in Italy are often run by joint stock companies controlled by public agencies such as Regional and Municipal Administrations. Due to this transformation, these companies must comply with a set of diverse expectations coming from a wide range of stakeholders, related to their financial, competitive and social performance. Such fragmented governance increases the presence of “wicked” problems in the decision-making sphere of these entities. Given this multi-level governance structure, ho…

Improving performance and fostering accountability in the public sector through system dynamics modelling: From an ‘external’ to an ‘internal’ perspe…

2010

This paper aims to outline the benefits justifying a tailored approach to System Dynamics (SD) modelling in the public sector, to improve performance and foster decision makers' accountability. The need of combining an ‘internal’ with an ‘external’ perspective (in respect to decision makers) in developing SD models is claimed. Different levels of intervention (i.e. macro, micro and meso) are discussed. Two case studies are analysed. The first one demonstrates how a dynamic resource-based view (DRBV) can support an analysis of the impact of back and front office units on a public sector organization's performance drivers. The second case shows how SD modelling based on a DRBV can also be app…

The effect of inventory record inaccuracy in information exchange supply chains

2015

Abstract The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain under shrinkage errors in the inventory item recording activity of their nodes, present the mathematical formulation of such supply chain model, and conduct a numerical simulation assuming different levels of errors. Results clearly show that Inventory Record Inaccuracy strongly compromises supply chain stability, particularly when moving upwards in the supply chain. Important managerial insights…

HOME COUNTRY INSTITUTIONAL EFFECTS ON INTERNATIONAL COMPETITIVENESS

2023

La qualità delle istituzioni di un Paese ha un effetto significativo sulla sua performance economica. Istituzioni forti possono garantire un'allocazione efficiente delle risorse, ridurre l'incertezza e gli attriti e favorire il coordinamento tra gli agenti economici. Al contrario, istituzioni deboli determinano una riduzione degli investimenti, un rallentamento della crescita della produttività e una minore crescita del PIL. Buone istituzioni favoriscono le sinergie tra gli investimenti diretti esteri e le imprese locali, nonché le ricadute di produttività. Al contrario, istituzioni poco sviluppate possono interferire con le attività produttive e impedire lo sfruttamento delle ricadute di c…
