Intervalli di confidenza degli scenari nella valutazione d'investimento
No full textLa marcata instabilità del quadro sociale, economico e politico nel quale gli investimenti vengono attuati rende necessaria la verifica ex ante dell’esito dei progetti su un ventaglio di possibili scenari futuri, contraddistinti da un set di variabili strategiche.
Il lavoro propone un criterio di definizione degli scenari evolutivi di un fenomeno basato sulla costruzione di intervalli di confidenza per la media di una popolazione, a partire da serie storiche correntemente reperibili.
Una esemplificazione della procedura è effettuata per un’ipotesi di investimento immobiliare da realizzare in un ambito urbano
L’analisi delle serie storiche per la gestione degli aspetti incerti nella stima indiretta del reddito aziendale
No full textDefinizione del piano economico-finanziario di un’opera infrastrutturale
No full textLa realizzazione di un progetto porta necessariamente in primo piano il problema del reperimento delle risorse monetarie e quello dell’incidenza che il costo dei capitali è destinato ad avere sui risultati dell’intervento. Di qui l’importanza di verificare, accanto alla convenienza economica, la fattibilità finanziaria dell’iniziativa, ma ciò impiegando nelle valutazioni strumenti in grado di razionalizzare l’utilizzazione delle diverse fonti di finanziamento.
Nel presente lavoro sono, perciò, innanzitutto analizzate le differenze di significato che i due termini “convenienza economica” e “fattibilità finanziaria” assumono nell’ambito della valutazione dei progetti e nell’ambito delle operazioni di finanza aziendale, dove detti strumenti vengono di norma impiegati. Sono poi introdotti gli schemi di determinazione dei flussi di cassa adoperati dagli analisti in presenza e in assenza degli oneri connessi alla struttura finanziaria del progetto. Sono quindi descritti gli indicatori di convenienza economica e gli indicatori di fattibilità finanziaria più frequentemente utilizzati per il “montaggio” del piano economico-finanziario dell’opera.
Per la definizione del piano economico-finanziario di un’opera infrastrutturale, il modello operativo considerato è stato in questo lavoro applicato al progetto della metropolitana di Salerno
Decision support methods for public-private partnerships: an application to the territorial context of the Apulia Region (Italy)
No full textIn this research a methodology to support decisions of Public Administrations in the definition of planning parameters of urban regeneration initiatives to be implemented with the involvement of private investors is applied. The decision support method proposed borrows the logic of the Break-Even Analysis. The model is applied to an urban area located in a city of the Apulia Region (Italy), which has been promoting urban redevelopment policies, investing significant public funding. The results highlight the simplicity and flexibility of the model, the phases of which are easily implementable in any territorial context
House Prices and Rents. The Italian Experience
Full text linkThe sale and lease real estate markets have cyclical developments which are often dissimilar in the short term and then take coincident trends in longer horizons. The imbalance in the relationship between prices and income is normally used by economists to determine any "housing bubbles". However, the structural limitations require caution in the use of the ratio between prices and rents as an indicator of an over - or under - evaluation in the real estate market. The present work has investigated the relationships between selling and rental prices in the Italian housing market, trying to define the actual cause-effect relationships in quantitative terms too. It was used a multivariate autoregressive (VAR) model to interpret the mutual influences between the two sectors and the macroeconomic fundamentals . The results show that housing prices can influence rents, but not the opposite. The Italian housing demand, even the one for investment , does not consider rent as a proxy for the corresponding dividend
An empirical analysis of winning bids in public procurement in the Italian construction sector
Full text linkThe survival of a construction company depends on its ability to minimize the total cost of production in the long run. The long run cost curves reflect the production technology and the organizational structure of a company. These elements are the result of choices made by the entrepreneur and they are certainly influenced by the economic environment where the company is working. This study analyses the discount of the winning bids in the contracts for public works in the construction industry recorded over a sufficiently large and homogeneous period with respect to general external conditions. Based on known microeconomic models and on some specific assumptions, the winning discounts have been used to draw the long run cost curves. In turn, these cost curves have allowed to detect and classify different business strategies in the organization of companies operating in different Italian regions. The work must be attributed equally to the three authors
Appraisal and Evaluation in the Production of Works for the Transformation of the Contemporary City
No full textThe sustainability of urban forestry projects: a model of multi-criteria economic analysis
No full textThe presence/spread of natural elements (urban forests) within the consolidated urban fabric can represent a strategic resource for cities’ sustainable development in eco-systemic logic. The interventions execution aimed at implementing integrated urban forestry projects, especially in territorial areas characterized by insufficient levels of collective services, limited recreational areas and high air pollution, allows both to growing the environmental quality level by improving the microclimate and conserving biodiversity, both to support the socio-economic development of these city parts through eco-system services for population. Although the multiple effects generated by actions based on eco-systemic logics are now recognized – “Eco-systemic Integrated Projects” (EIP) – within urban policies this type of integrated intervention is still little used as a possible solution for the cities’ smart growth. This is due to the interest in preferring actions with immediate financial effects, and due to the difficulty in carrying out evaluations on EIP not only concerning specific aspects (of an environmental, social, economic nature), but taking into account in an integrated manner the multidimensional and multi-criteria characteristics that define projects of this nature according to an eco-systemic logic. The aim of the present work is to define a set of criteria and indicators, value components not only referring to environmental, but also financial, social and cultural aspects, with which the EIP projects can be evaluated with an integrated way. These indicators are derived by relating the features (Targets) of the urban context of reference with the ecosystem service type offered (Key Issue). These can be used in the application of different evaluation tools to support the decision-making process of both public and private subjects, that are involved in this intervention type, according to the different evaluation questions to be solved regarding, for example, the interventions’ economic value and the benefits distribution between the public and private sectors
