Common-Property Resource Exploitation: A Real Options Approach

Abstract

Agricultural land and forestlands can have multiple uses and generate multiple sources of utility. Although landowners benefit from most of them, society can benefit from others because of their intrinsic characteristics as common-property resources and customary practice. In many Italian territories, the picking of mushrooms is allowed on privately owned agricultural land and in forests. The management of these resources is challenging due to the emerging conflicts between landowners and users. In addition, the pressure exerted by users gives rise to issues on stock preservation, thus contributing to putting biodiversity at risk in contexts already heavily jeopardized by modern agriculture. Through the years, regulation established the primacy of the landowner’s right, introduced a permit fee for users, and set limits on the resource stock to be collected daily. Nonetheless, the relationship between public and private interests in common-property resource exploitation is still controversial. In this paper, we investigate and model a right holder’s decision whether to exploit a common-property resource according to their actual status of being an actual or potential user. The model is developed within the real options valuation framework. In detail, we investigate the entry/exit decision on the exploitation of the resource by considering the uncertainty that affects the resource stock, the entry/exist costs, and the number of rival users.

The Collective Domains in the Ecological Transition: A Preliminary Analysis in an Inner Area in the Campania Region, Italy

“…The present value of collective domains in the Campania region can be better understood through a study by D'Alpaos et al [50]. They interpreted the historical vicissitudes of collective domains throughout the country by analyzing the relationship between the evolution of land productivity and the degree of socioeconomic development.…”

Risk Assessment in Sustainable Infrastructure Development Projects: A Tool for Mitigating Cost Overruns

“…Several innovative approaches have emerged for managing cost overrun including structural equation modeling, Monte Carlo simulation, decision support system tools, and the use of multi-criteria decision model techniques [13][14][15][16][17][18]. Recent publications have extensively explored the applications of artificial-intelligence-based models to effectively manage complex, uncertain, and vulnerable cost-risk correlations [19][20][21][22][23][24][25]. On this topic, an important and substantial contribution to research was made by Flyvbjerg, who introduced the concept of reference class forecasting (RCF) as an alternative to traditional methods of cost estimation.…”

“…In recent years, many scholars have begun to differentiate among the diverse configurations of communal ownerships. Most contemporary models of common property explain it as an asset over which a discrete group of people shares ownership rights and exerts exclusionary power (D'Alpaos et al, 2023;Peredo et al, 2018;Sugden & Punch, 2014). Rather than being a prototype of private or common land ownership, incremental iterations of China's HRS reveal a complex ownership system in which private and communal characteristics interact to allow for unexpected outcomes.…”
