Evolution of harvesting strategies: replicator and resource dynamics

Abstract. Economic theories of managing renewable resources, such as fisheries and forestry, traditionally assume that individual harvesters are perfectly rational and thus able to compute the harvesting strategy that maximizes their discounted profits. The current paper presents an alternative approach based on bounded rationality and evolutionary mechanisms. It is assumed that individual harvesters face a choice between two harvesting strategies. The evolution of the distribution of strategies in the population is modeled through a replicator dynamics equation. The latter captures the idea that strategies yielding above average profits are demanded more than strategies yielding below average profits, so that the first type ends up accounting for a larger part in the population. From a mathematical perspective, the combination of resource and evolutionary processes leads to complex dynamics. The paper presents the existence and stability conditions for each steady-state of the system and analyzes dynamic paths to the equilibrium. In addition, effects of changes in prices are analyzed. A main result of the paper is that under certain conditions both strategies can survive in the long-run. Correspondence to: J. Noailly     

Innovation and Performance: Benchmarking Australian Firms

This article empirically analyses the link between innovation and performance using a sample of large Australian firms, with a specific aim of developing benchmarking tools. Innovation is measured by firms' investment in R&D and applications for patents, trademarks and designs. An innovation index is constructed to provide one method of benchmarking. The index incorporates a firm's innovative activities into a single figure after accounting for firm size. The index provides a ranking of the most innovative firms in Australia. A second method of benchmarking uses a stochastic production frontier. This type of analysis identifies the firms which are located closest to a ‘best practice innovation frontier’.     

Enterprise Bargaining and Productivity in Australia: What do We Know?

There appears to be widespread consensus, at least in industry and government, that enterprise bargaining has been beneficial for productivity. Many academics, however, have argued that the link between bargaining structure and workplace productivity is a contentious one, and that research has been unable to establish a relationship. The present paper re-examines the existing evidence. The review reinforces the need to exercise caution before asserting that enterprise bargaining is necessarily beneficial for workplace productivity. The main conclusion that emanates from this review, however, is not the absence of a clear-cut finding, but how poorly developed the relevant research literature is.     

Investigating regional house price convergence in the United States: Evidence from a pair-wise approach

In this paper we examine long-run house price convergence across US states using a novel econometric approach advocated by Pesaran (2007) and Pesaran et al. (2009). Our empirical modelling strategy employs a probabilistic test statistic for convergence based on the percentage of unit root rejections among all state house price differentials. Using a sieve bootstrap procedure, we construct confidence intervals and find evidence in favour of convergence. We also conclude that speed of adjustment towards long-run equilibrium is inversely related to distance.     

Mitigating shortage and distribution costs in damaged water networks

Recent events have sparked renewed interest in disaster mitigation for public infrastructures. Presidential Decision Directive 63 identifies water distribution as being among the most vital and vulnerable of our large-scale infrastructures. Water distribution networks are vulnerable to threats such as chemical and biological contamination, cyber attacks on computer-based management systems, and physical destruction from acts of nature and intentional attack. This research develops methods for configuring the undamaged portion of the water network to mitigate the consequences of physical destruction. The approach is to find a hydraulically feasible residual network that can be pressurized to meet the demand of a subset of demand sectors. Demand sectors not pressurized then receive water through truck distribution from pressurized sectors. The objective is to minimize weighted water shortage and water truck distribution costs by identifying sectors to pressurize along with an assignment of unpressurized sectors to pressurized sectors for water delivery by truck. The paper develops an optimization model, describes a solution method, and presents computational results for three example networks.     

Buyer–supplier interaction in business-to-business services: A typology test using case research

We empirically test a theory specifying distinct ideal interaction patterns for four business-to-business service types, which differ with regard to how they are used by the buying company. The ideal interaction patterns are conceptualised as configurations of five different interaction dimensions: the key objectives in the interaction, the critical capabilities on either side of the relationship, the type of functional involvement from the buying firm and the key issues in the buyer–seller dialogue. Using a combination of quantitative and qualitative data from 23 cases of service exchange at six buying organisations we test whether similarity between the ideal interaction pattern and an actual, observed interaction pattern is a continuous necessary condition for successful ongoing service exchange. The findings suggest for each of the four service types that, in order for a service exchange to be successful, buying companies should design their interactions with their service providers to closely resemble the specified ideal pattern for that specific service type. Besides contributing to the knowledge on how to effectively structure buyer–supplier interactions across the heterogeneous spectrum of services bought, a methodological contribution is made by showing how case research can be used for theory-testing purposes. As this study is the first real test of the typology, further replications with new data, preferably obtained from both sides of the buyer–supplier dyad, are necessary.     

What pupils can learn from working with robotic direct manipulation environments

This study investigates what pupils aged 10–12 can learn from working with robots, assuming that understanding robotics is a sign of technological literacy. We conducted cognitive and conceptual analysis to develop a frame of reference for determining pupils’ understanding of robotics. Four perspectives were distinguished with increasing sophistication; “psychological”, “technological”, “function”, and “controlled system”. Using Lego® Mindstorms® NXT robots, as an example of a Direct Manipulation Environment, we developed and conducted a lesson plan to investigate pupils’ reasoning patterns. There is ample evidence that pupils have little difficulty in understanding that robots are man-made technological and functional artifacts. Pupils’ understanding of the controlled system concept, more specifically the complex sense-reason-act loop that is characteristic of robotics, can be fostered by means of problem solving tasks. The results are discussed with respect to pupils’ developing technological literacy and the possibilities for teaching and learning in primary education.
