Murphy, Michael John Alexander. "Understanding risk & adoption in response to environmental uncertainty." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0498.
Full textIndividuals must often make decisions under conditions on uncertainty, where the risks associated with their choices are difficult or impossible to quantify. This is particularly true of interactions with the environment where economic agents may lack understanding of complex natural systems. Using three studies of decision-making in the context of food systems in developing economies, this thesis examines individual decisions to change behaviour in response to environmental uncertainty. The chapters of the thesis each explore this topic in a different setting, using a distinct set of analytical techniques. The first chapter analyzes a framed field experiment carried out with farmers in northern Ghana. It focuses on uncertainty surrounding the benefits associated with a set of agroecological practices known collectively as ‘conservation agriculture’ techniques. These practices have public good characteristics, but whereas the cost to adoption is immediate, the private benefits to producers accrue over time. The incentivized experiment simulates the farmer’s decision to adopt (or not adopt) conservation agriculture practices across seasons. The analysis tests the effectiveness of two approaches to reducing uncertainty around the private benefits associated with adoption, in order to evaluate potential policy approaches to encourage take-up. The second chapter is a secondary panel data analysis looking at the effect of temperature shocks on wheat production in India in the context of the Green Revolution. Uncertainty around weather outcomes has always been a concern of farmers, but understanding how producers adapt- or fail to adapt- to unpredicted weather is an increasingly urgent question in the age of global warming. I apply recent advances in the econometrics of estimating agricultural adaptation to climate to a novel panel dataset and explore how the adoption of Green Revolution technology in the form of high-yielding variety seeds and associated inputs affected farmers’ ability to adapt to temperature shocks. The third chapter focuses on consumers, implementing a randomized control trial with low-income urban households in Kenya. The study provides treated households with salient information on a food safety issue- aflatoxin contamination of maize flour- using data from a prior study carried out in the area. The analysis examines how providing participants with information about this hazard affects their subjective risk perceptions, and in turn how this belief updating affects their purchasing behaviour. Across these three different settings, the thesis show how different microeconomic approaches to causal inference can help to understand how individuals respond to a changing environment. These findings aim to improve our understanding of decision-making under uncertainty in contexts where it is rarely studied, and also aim to contribute to a practical evidence base for policymakers in developing countries to design welfare-enhancing policies that enhance citizen access to information and new technologies

Full textEnvironmental risks (the greenhouse effect, acid rains. . . ) take place in a context of ecological globalization and complexity. This result justify our work about decisionmaking based on specific hypothesis of rationality and their abibilty to rationalize some choices of environmental preservation. In complete information, game theory modelize strategic interactions in the field of environmental risks. This analysis, based on substantive rationality, suppose that the instrumental and cognitive rationalities of the agents are strong. We point out this kind of hypothesis is limited to rationalize and explain the choices of environmental preservation. Then we study situations of incomplete information. The expected utility theory, based on substantive rationality, suppose that the cognitive rationality of the agents is a little bit weakened. We developp the reasons why this approach don't take complexity and indetermination into consideration. This results justify the necessity to adopt a larger criterion of rationality called procedural rationality. The naiade method, based on this hypothesis of rationality, suppose that the instrumental and cognitive rationalities of the agents are weakened. We illustrate how this method which articulates multicriteria analysis and fuzzy set theory justify some choices of environmental preservation

Full textCoastal and marine ecosystems are some of the most heavily exploited with increasing degradation. This alarming situation appeals for urgent and effective actions. The optimal balance between use and conservation of ecosystems theoretically requires all costs and benefits to be considered in decision-making, including intangible costs and benefits such as non-market use and non-use values. The broad aim of this PhD is to examine how these economic values associated with coastal and marine ecosystem services can be measured, and how the economic valuation exercise may be considered and influence management decision- making.The first analytical part of the thesis focuses on assessing non-market use and non-use values, through econometric methods. The characterization and estimation of non-use values are complex and controversial, especially when the valuation exercise is focusing on individuals who are users of the ecosystem services being considered. An original approach based on a stated preference method, namely choice experiments, is developed then empirically applied in quantifying non-market values for marine and coastal ecosystems in two areas in New Caledonia. It allows the estimation of non-use values for populations of users in an implicit way. An in-depth analysis of the individuals’ choice heuristics during the valuation exercise is also conducted, with a focus on payment non-attendance. This issue is dealt with by comparing multiple modelling approaches in terms of: (1) inferred attendance, in relation to stated attendance; (2) attendance distribution according to several socio-economic variables; and (3) welfare estimates.After noting that the potential influence of economic valuation in decision making is unclear and largely unexplored in the literature, the second major component of this PhD aims to examine if, how and to what extent the economic valuation of ecosystem services, including measures of non-market values, influence decision-making regarding coastal and marine ecosystems management in Australia. Based on two nation-wide surveys, the perceived usefulness of the economic valuation of ecosystem services by the general public and decision-makers is studied, and the reasons why decision-makers may or may not fully consider economic values are elicited. Using a multi-criteria analysis, a part of the surveys also aims at examining the relative importance of different evaluation criteria (ecological, social and economic) when assessing the consequences of a hypothetical coastal development project on commercial activities, recreational activities and marine biodiversity

Full textThe Physical Internet (PI) is an initiative that identifies several symptoms of logistics systems unsustainability and inefficiency and tackles them by proposing a novel paradigm called Hyperconnected Logistics. Similar to the Digital Internet, which connects thousands of personal and local computer networks, PI will connect the fragmented logistics systems of today. The main purpose is to enhance the performance of logistics systems from economic, environmental and social perspectives. Focusing specifically on the distribution system, this thesis questions the order of magnitude of the performance gain by exploiting the PI-enabled hyperconnected distribution. It is also concerned by the characterization of the hyperconnected distribution planning. To address the first question, an exploratory research approach based on optimization modeling is applied; first, the current and prospective distribution systems are modeled. Then, a set of realistic business samples are created, and their economic and environmental performance by targeting multiple social performances are assessed. A conceptual planning framework is proposed to support the decision making in the hyperconnected distribution system. Based on the results obtained by our investigation, it can be argued that a substantial gain can be achieved by shifting toward Hyperconnected Distribution. It is also revealed that the magnitude of the gain varies by business characteristics and the targeted social performance. Since the Physical Internet is a novel topic, chapter 1 briefly introduces PI and Hyperconnected Logistics. Chapter 2 discusses the research foundations, goal and methodology. It also describes the challenges of conducting this research and highlights the type of contributions aimed for. Chapter 3 presents the optimization models including a core distribution network design modeling approach. Influenced by the characteristics of the current and prospective distribution systems, three distribution system-driven models are developed. Chapter 4 engages with the characterization of the business samples, the modeling and calibration of the parameter that are employed in the models. The exploratory investigation results are presented in Chapter 5. Chapter 6 describes the hyperconnected distribution planning framework. Chapter 7 summarizes the content of the thesis and highlights the main contributions. Moreover, it identifies the research limitations and potential future research avenues.
