Kenneth Boulding's Theories of Evolutionary Economics and Organizational Change: A Reconstruction

I identify a discrepancy between Kenneth Boulding's wide-ranging contributions to evolutionary economics and his professed ecological approach to it. I argue that Boulding has undersold his true contributions to evolutionary economics by trying to embed them into the ecological approach. I endeavor to overcome this discrepancy by differentiating between two types of evolutionary change analyzed in Boulding's writings: ecological change and civilizational change. In contrast to ecological change, civilizational change entails the possibility for the evolving system to overstrain the carrying capacity of the environment, thus suggesting the precarious relationship between civilizational complexity and sustainability. This argument sheds new light on Boulding's theory of “social organizers,” such as exchange, threat, and the integrative system. Boulding's understanding of civilizational change envisages the key role of threat and exchange in enabling civilizational complexity, while the integrative system is called upon to make this complexity sustainable.     

Social ecology,sustainability, and economics

What mode of analysis might be employed, that captures the confluent action of material and social systems acting together? The framework of Social Ecology, which first emerged as a rejoinder to the Chicago School of Human Ecology of the early 1900s, evolved over subsequent decades as an attempt at such integration. We revisit social ecology's historical origins and foundational assumptions. We propose that the social ecological framework can offer useful conceptual grounding to scholars of ecological economics. We illustrate how this analytical lens affords a deeper understanding of unsustainable systems and valuation problems.     

Biological conservation in dynamic agricultural landscapes: Effectiveness of public policies and trade-offs with agricultural production

Land use change and land management intensification are major drivers of biodiversity loss, especially in agricultural landscapes, that cover a large and increasing share of the world's surface. Incentive-based agri-environmental policies are designed to influence farmers' land-use decisions in order to mitigate environmental degradation. This paper evaluates the effectiveness of agri-environmental schemes for biological conservation in a dynamic agricultural landscape under economic uncertainty. We develop a dynamic ecological economic model of agricultural land-use and spatially explicit population dynamics. We then relate policies (subsidies to grassland, taxation of agricultural intensity) to the ecological outcome (probability of persistence of a species of interest). We also analyze the associated trade-offs between agricultural production (in value) and biological conservation (in probability of persistence) at the landscape scale.     

Groundwater balance and conservation under different water pricing and agricultural policy scenarios: A case study of the Hamadan-Bahar plain

Government subsidies for agricultural activities in recent decades have encouraged farmers of Hamadan-Bahar plain to extend the number of wells and irrigated farms, with no consideration of groundwater resource conservation. As a result, the level of the groundwater table has decreased continuously in this area, threatening the life of groundwater aquifer. The objective of the study is to analyze the impacts of irrigation water pricing and agricultural policy scenarios on aquifer conservation by considering the dynamic relations between aquifer groundwater balance and the agriculture sector. For this purpose a combination of simulation and optimization techniques is considered in a dynamic framework. Firstly, dynamic treatments of groundwater and the main factors affecting the balance of studied aquifer are simulated. Then, optimization behaviour of agriculture sector related to farmers' decision-making processes is defined on the time horizon. Thereafter all of the equations are used simultaneously by a non-linear dynamic programming method, which maximize present value of gross margins of agriculture sector subject to groundwater constrains and other input limitations. The analysis of the results indicates that water pricing by itself can considerably reduce the agricultural demand for aquifer groundwater in the Hamadan-Bahar plain.     

Reducing farmers' poverty vulnerability in China: The role of digital financial inclusion

This paper applies exogenous shocks to investigate the impact of digital financial inclusion (DFI) on farmers' poverty vulnerability in China. We find that farmers in highly developed DFI areas are less vulnerable to the poverty trap. The result is robust to various checks, including propensity score matching and difference-in-differences method and the instrumental variable approach. Moreover, we find that income diversification is the possible economic channel through which DFI affects farmers' poverty vulnerability. Further analyses show that DFI has a “targeting” effect on those who are poor and vulnerable, and a synergistic effect by working with medical insurance and informal finance in terms of reducing farmers' poverty vulnerability. Our research findings provide new theoretical insights and useful guidance in enhancing financial inclusiveness and sustainable development in the post-COVID-19 era.     

Input-Orientated Data Envelopment Analysis Framework for Measuring and Decomposing Economic,Environmental and Ecological Efficiency: An Application to OECD Agriculture

This paper presents an input-orientated data envelopment analysis (DEA) framework which allows the measurement and decomposition of economic, environmental and ecological efficiency levels in agricultural production across different countries. Economic, environmental and ecological optimisations search for optimal input combinations that minimise total costs, total amount of nutrients, and total amount of cumulative exergy contained in inputs respectively. The application of the framework to an agricultural dataset of 30 OECD countries revealed that (i) there was significant scope to make their agricultural production systems more environmentally and ecologically sustainable; (ii) the improvement in the environmental and ecological sustainability could be achieved by being more technically efficient and, even more significantly, by changing the input combinations; (iii) the rankings of sustainability varied significantly across OECD countries within frontier-based environmental and ecological efficiency measures and between frontier-based measures and indicators.     

Incentives and Voluntary Investment in Employer Shares

Using a partial equilibrium model, this paper makes a first attempt to provide an explanation based on rational behaviour for the basic big puzzle of why workers have large holdings of the shares of their employer in their defined contribution (DC) pension plans. The primary explanations in the literature seem to be behavioural ones that involve sub‐optimal behaviour. This paper attempts to see how far a standard optimizing setting in a principal–agent type framework can go in explaining the same phenomenon. It uses an incentive approach involving two agents, senior managers and workers to show how portfolio weights can be voluntarily shifted away from what would be first best in the absence of an incentive problem.     

Relative and absolute scarcity of nature. Assessing the roles of economics and ecology for biodiversity conservation

Our aim in this essay is to identify and analyze some of the difficulties with interdisciplinary integration of economic and ecological contributions to the study of biodiversity loss. We develop our analysis from a widely accepted definition of economics which is based on the concept of scarcity. Taking a closer look at this notion, we find that economics actually limits itself to a very particular aspect of scarcity, which we denote as relative scarcity. We describe in what respect the economic approach towards biodiversity is based on this notion, and also reflect on the specific understanding of the relation of humans and nature behind the economic approach. We then turn to absolute scarcity as another notion of scarcity, and show that this is not within the scope of economics, but has been a theme of ecology and ecological economics. We describe in which way ecological and ecological–economic approaches towards biodiversity are based on the idea of absolute scarcity, and also reflect on the specific understanding of the human–nature relationship behind this notion of scarcity. Against this background, we discuss the roles of economics and ecology for nature conservation. We conclude that the interdisciplinary integration of ecology and economics requires a philosophical underpinning, and suggest a framework for further research.

Building smallholder farmers' capacity to adopt climate-smart agricultural practices in flood prone areas: Lessons from Bangladesh

Currently, there is an increased interest in promoting climate-smart agricultural practices (CSAPs) around the globe, however, application of these practices may vary for different climate risk hotspots. Although, climate field schools (CFS) are conducted with the aim of empowering farmers with knowledge on the various agricultural practices, little attention has been devoted to building the capacity of smallholder farmers to facilitate adoption of appropriate CSAPs. Given the effects of climate change on agriculture, it is fundamental for agricultural sustainability to answer the question that has hardly benefited from empirical analysis in previous land use studies, which is: Do CFS build farmers' capacity to adopt CSA in flood prone areas? Cross-sectional data from 600 rural farm households in south Bangladesh is used and the recursive bivariate probit (RBP) is applied to address this knowledge gap. The results reveal that participation in CFS increases the probability of a farmer's soil salinity consciousness by 25% and eventually improves the probability to adopt climate-smart agricultural practices by 20%. We also analyzed the spillover effects of CFS participation on CSA adoption and found that there is a strong spillover effect which has important implications on the cost effectiveness and sustainability of the program. Overall, the study provides empirical evidence demonstrating that participatory approaches stimulate adoption of appropriate CSAPs by building farmers' capacity in recognizing the existing climate risk hotspots.     

“Psychological” elements in business cycle theories: old approaches and new insights

This paper identifies a number of “psychological” elements in business cycle theories and shows how these components contribute to the theories’ results. It proceeds by discussing (i) which assumptions on behaviour were used, laying particular stress on expectations and confidence, money illusion, social preferences and interaction, and individual character traits; (ii) how they influenced and determined the theories’ results; and (iii) how more recent behavioural research provides a better and empirically grounded understanding of these factors. For each element, the possibility of incorporating new insights into older models is discussed, and references to work which already does so are given.     

Beauty contested: how much of Keynes' remains in behavioural economics' beauty contests?

Abstract

In one of the most famous passages of the economic literature, John Maynard Keynes likens the stock market to a beauty contest (BC), in which the winners are those who anticipate the average opinion. In behavioural economics there have recently been attempts at investigating the BC experimentally. We argue that there exist important differences between Keynes' and behavioural economics' BCs. We identify several types of BCs and propose a taxonomy. We also suggest that, in spite of these differences, Keynes' theory of decision under uncertainty is central to understanding the actual behaviour observed in experimental BCs.     

Multi-agent simulations to explore rules for rural credit in a highland farming community of Northern Thailand

Multi-agent systems (MAS) open new modelling and analysis perspectives in ecological and social sciences. An original characteristic of the companion modelling (ComMod) approach adopted in this case study is the co-construction and use of a MAS model with and for local stakeholders such as farmers and local administrators. Alternating iteratively field and modelling activities, this approach facilitates collective learning among local stakeholders and between them and the researchers. Combining the use of MAS models with role-playing games (RPG), the described experiment aimed to facilitate collective decision-making in a socially heterogeneous community of small farmers in mountainous Northern Thailand about the local rules for the allocation of rural credit to allow a more equitable and extensive process of expansion of non-erosive perennial crops in a watershed prone to erosion. This paper presents the MAS model and the results of a series of simulations exploring the ecological, social and economic effects of various rules for formal and informal credit suggested by the villagers-participants. Six scenarios considered as pertinent to further explore the participants' suggestions were defined based on different combinations among the following three variables: (i) Duration for the reimbursement of loans, (ii) Mode of allocation of formal credit among three different types of farms, (iii) Configuration of networks of acquaintances for access to informal credit.Drawing on this case study, we first elaborate on the potential of bottom-up models such as MAS to analyze the functioning of agricultural systems, in particular farm differentiation and rural credit dynamics. We highlight the ability of MAS to deal with interactions between social and ecological dynamics and to provide an alternative to classical economic thinking by analyzing the effects at the village level of social interactions among individuals. MAS allow us in particular to trigger an overlooked but nevertheless fundamental aspect of socio-ecological systems, i.e. social capital which is a determining factor when dealing with sustainability issues. The second question addressed in this paper deals with the potential and limits of MAS models to support a bottom-up (or participatory) modelling approach. This experiment suggests that the usefulness of models relies much more on the modelling process than on the model itself, because a model is usually useless if it is misunderstood by its potential users, or if it does not respond to their current preoccupations. The intuitive representation of real systems provided by MAS and their high flexibility are the two underlined characteristics favouring their appropriation by local stakeholders.     

The determinants of household recycling: social influence,public policies and environmental preferences

Our article aims at understanding the determinants of households’ selective waste-sorting behaviours, based on data from an original survey of 694 individuals in the French Provence–Alpes–Côte d’Azur region. The applied literature focuses mainly on countries with high recycling rates. We focus on a region with the lowest recycling rate in France, a country that recycles less than the European country average. We first apply polychoric principal components analysis to reduce the number of explanatory variables to a set of six factors. In a second step, we use a probit model to estimate the probability of waste sorting as a function of these factors. This model tests several hypotheses emerging from the recent literature on behavioural economics applied to households’ selective sorting. This literature pays particular attention to the social influence on recycling behaviour, which has been studied mostly by sociologists and psychologists. The results of our empirical analysis confirm some of the findings in the literature. However, they also highlight some unique features, such as social influences having a negative impact on recycling. This finding contrasts with most of the literature, which finds a positive relationship of social influence on pro-environmental behaviour.     

Socio-ecological accounting: DPSWR,a modified DPSIR framework,and its application to marine ecosystems

In contrast to institutionally focussed environmental accounting, socio-ecological accounting frameworks organise information concerned with human–environment interactions at scales relevant to ecosystem change and thus encapsulate information more relevant to ecosystem-based management. The DPSIR (Driver–Pressure–State–Impact–Response) framework has been used to identify relevant information in a number of ecosystem contexts but suffers limitations in terms of its definitional clarity and conceptual foundations, which undermine comparability between studies. These limitations are addressed in the DPSWR (Driver–Pressure–State–Welfare–Response) framework, which defines information categories based on a synthesis of concepts in DPSIR and its predecessors so as to more clearly identify the object of measurement in each category and isolate information relating to social systems. Consequently, its categories dealing with social systems are better suited to assessing anthropocentric trade-offs in environmental decision-making, such as through cost–benefit analysis. A conceptual input–output analysis is used to highlight measurement issues connected with the inter-relations between information categories, particularly with regard to scale, and the application of the framework is illustrated by reference to issues affecting marine ecosystems included in a Europewide study for the European Commission. However, DPSWR's definitions are designed to be sufficiently general as to support application in other ecosystem contexts.     

Expanding the solution set: Organizational economics and agri-environmental policy

The market failure paradigm dominates agri-environmental research and policy. Organizational economics provides an alternative framework for analyzing agri-environmental problems and points to alternative solutions. In this paper, the traditional approach of creating markets for environmental goods and services is critiqued and set aside to provide space for an organizational analysis. From an organizational perspective, the relationship between the state and agricultural agents is viewed as grounded in an over-arching exchange relationship including elements of cooperation and trust. Such a collaborative exchange relationship may prove useful in supporting exchange between agricultural agents and the state leading to the provision of ecological goods and services. Highlighting the potential of organizational economics, the analysis suggests that agri-environmental research and policy go further in accounting for, and investigating, the unique organizational modes of exchange governing the production of food, fiber, and ecological goods and services.     

Political ecology and ecological resilience:: An integration of human and ecological dynamics

The biosphere is increasingly dominated by human action. Consequently, ecology must incorporate human behavior. Political ecology, as long as it includes ecology, is a powerful framework for integrating natural and social dynamics. In this paper I present a resilience-oriented approach to political ecology that integrates system dynamics, scale, and cross-scale interactions in both human and natural systems. This approach suggests that understanding the coupled dynamics of human-ecological systems allows the assessment of when systems are most vulnerable and most open to transformation. I use this framework to examine the political ecology of salmon in the Columbia River Basin.     

Managing complex adaptive systems — A co-evolutionary perspective on natural resource management

The overexploitation of natural resources and the increasing number of social conflicts following from their unsustainable use point to a wide gap between the objectives of sustainability and current resource management practices. One of the reasons for the difficulties to close this gap is that for evolving complex systems like natural and socio-economic systems, sustainability cannot be a static objective. Instead sustainable development is an open evolutionary process of improving the management of social-ecological systems, through better understanding and knowledge. Therefore, natural resource management systems need to be able to deal with different temporal, spatial and social scales, nested hierarchies, irreducible uncertainty, multidimensional interactions and emergent properties. The co-evolutionary perspective outlined in this paper serves as heuristic device to map the interactions settled in the networks between the resource base, social institutions and the behaviour of individual actors. For this purpose we draw on ideas from complex adaptive systems theory, evolutionary theory and evolutionary economics. Finally, we outline a research agenda for a co-evolutionary approach for natural resource management systems.     

A model of the behavior of farmers and its application to agricultural policies

In this paper, we examine the practical implications for agricultural policies of a model of farmers' behavior. Part I describes the main features of the model and illustrates by empirical evidence the reasons why it seems to be relevant in explaining actual behaviors.
