Methodological individualism: True and false

I apply Hayek’s distinction between ‘true’ and ‘false’ individualism to methodological individualism. Hayek traced ‘false’ individualism to Cartesian rationalism; Hayek’s rejection of Mises’ praxeology was due to its rationalist underpinnings. The first half of this paper identifies praxeology’s foundational philosophical concepts, emphasising their Cartesian nature, and illustrates how together they constitute a case for methodological individualism: intuition and deduction; reductionism; judgement; dualism. In the second half of this paper, I draw upon philosophy and cognitive science to articulate ‘Hayekian’ (N.B. not Hayek’s) alternatives to these Cartesian concepts. The Hayekian alternative allows a ‘gestalt switch’ from the individual- to the system-level perspective. I therefore suggest that methodological individualism is both true and false: true, in that economic phenomena are grounded in the actions of individuals; false, in that certain problems might be reconceived/discovered at the system-level. I finish by suggesting three avenues of research at system-level: optimisation; stigmergy; computational complexity.     

Post‐Cameralist Governance: Towards a Robust Political Economy of Bureaucracy

I develop a robust political economy of bureaucracy by highlighting the conditions necessary for hierarchical administrative bodies to govern protectively and productively, but not predatorily. These conditions are residual claimancy and jurisdictional competition. I make this argument by exploring a post‐cameralist interpretation of governance. Cameralism arose as a governance philosophy in the fractured principalities of seventeenth‐century Germany following the Thirty Years' War. Post‐cameralism focuses not on particular cameralist governance strategies but on a paradigm which sees governance as an activity provided within a larger exchange order, rather than imposing itself on that order as in more conventional treatments of public economics. While a post‐cameralist conception of governance comes with its own challenges, such as tensions with normative visions that promote self‐governance, it nonetheless presents an intriguing synthesis of monocentric and polycentric insights.     

WHAT CAN WE LEARN FROM THE IMPLEMENTATION OF MONETARY AND MACROPRUDENTIAL POLICIES: A SYSTEMATIC LITERATURE REVIEW

The emergence of macroprudential policies, implemented by central banks as a means of promoting financial stability, has raised many questions regarding the interaction between monetary and macroprudential policies. Given the limited number of studies available, this paper sheds light on this issue by providing a critical and systematic review of the literature. To this end, we divide the theoretical and empirical studies into two broad channels of borrowers – consisting of the cost of funds and the collateral constraint – and financial intermediaries – consisting of risk‐taking and payment systems. In spite of the existing ambiguity surrounding coordination issues between monetary and macroprudential policies, it is argued that monetary policy alone is not sufficient to maintain macroeconomic and financial stability. Hence, macroprudential policies are needed to supplement monetary. In addition, we find that the role of the exchange rate is critical in the implementation of monetary and macroprudential policies in emerging markets, while volatile capital flows pose another challenge. In so far as how the arrangement of monetary and macroprudential policies varies across countries, key theoretical and policy implications have been identified.     

Challenges for land system science

While considerable progress has been made in understanding land use change, land system science continues to face a number of grand challenges. This paper discusses these challenges with a focus on empirical land system studies, land system modelling and the analysis of future visions of land system change. Contemporary landscapes are contingent outcomes of past and present patterns, processes and decisions. Thus, empirical analysis of past and present land-use change has an important role in providing insights into the socio-economic and ecological processes that shape land use transitions. This is especially important with respect to gradual versus rapid land system dynamics and in understanding changes in land use intensity. Combining the strengths of empirical analysis with multi-scale modelling will lead to new insights into the processes driving land system change. New modelling methods that combine complex systems thinking at a local level with macro-level economic analysis of the land system would reconcile the multi-scale dynamics currently encapsulated in bottom-up and top-down modelling approaches. Developments in land use futures analysis could focus on integrating explorative scenarios that reflect possible outcomes with normative visions that identify desired outcomes. Such an approach would benefit from the broad and in-depth involvement of stakeholders in order to link scientific findings to political and societal decision-making culminating in a set of key choices and consequences. Land system models have an important role in supporting future land use policy, but model outputs require scientific interpretation rather than being presented as predictions. The future of land system science is strongly dependent on the research community's capacity to bring together the elements of research discussed in the paper, via empirical data collection and analysis of observed processes, computer simulation across scale levels and futures analysis of alternative, normative visions through stakeholder engagement.     

The sources of use knowledge: Towards integrating the dynamics of technology use and design in the articulation of societal challenges

This paper reviews three strands of the innovation literature that have presented innovation as a distributed process that combines knowledge of designers and users: user innovations, Science and Technology Studies (STS), and domestication research. These literatures have explored different aspects of the micro-processes through which use and design knowledge are locally embedded. This paper pulls together insights from the literatures, and identifies an important gap: the connections between the local embedding of use and design knowledge, and the meso dynamics of industrial and technological change. The paper then develops a number of integrating concepts and propositions for a framework to study the co-evolution of use and design in innovation processes. It also demonstrates that this framework is most valuable in researching how societal challenges become articulated over time in processes of technological change and innovation.     

Electrification of a city bus network—An optimization model for cost-effective placing of charging infrastructure and battery sizing of fast-charging electric bus systems

The deployment of battery-powered electric bus systems within the public transportation sector plays an important role in increasing energy efficiency and abating emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive infrastructure to equip bus routes with charging stations. The combination of charging infrastructure and bus batteries needs a reliable energy supply to maintain a stable bus operation even under demanding conditions. An efficient layout of the charging infrastructure and an appropriate dimensioning of battery capacity are crucial to minimize the total cost of ownership and to enable an energetically feasible bus operation. In this work, the central issue of jointly optimizing the charging infrastructure and battery capacity is described by a capacitated set covering problem. A mixed-integer linear optimization model is developed to determine the minimum number and location of required charging stations for a bus network as well as the adequate battery capacity for each bus line. The bus energy consumption for each route segment is determined based on individual route, bus type, traffic, and other information. Different scenarios are examined in order to assess the influence of charging power, climate, and changing operating conditions. The findings reveal significant differences in terms of required infrastructure. Moreover, the results highlight a trade-off between battery capacity and charging infrastructure under different operational and infrastructure conditions. This paper addresses upcoming challenges for transport authorities during the electrification process of the bus fleets and sharpens the focus on infrastructural issues related to the fast charging concept.     

Direct Democracy and Local Public Finances under Cooperative Federalism

In this paper, we exploit the introduction of the right of local initiatives in the German state of Bavaria in 1995 in order to study the fiscal effects of direct democracy. Our identification strategy combines difference‐in‐differences and regression discontinuity methods: we compare municipal expenditure and revenue between pre‐ and post‐reform periods at population thresholds where the signatures needed to launch initiatives and minimum quorum requirements decrease discontinuously (difference‐in‐discontinuities design). The results suggest that stronger direct democratic institutions lead to an expansion of local government size.
