Dynamic efficiency

Abstract: The issue of dynamic efficiency is central to analyses of capital accumulation and economic growth. Yet the question of what characteristics should be examined to determine whether actual economies are dynamically efficient is unresolved. This paper develops a criterion for determining whether an economy is dynamically efficient. The criterion, which holds for economies in which technological progress and population growth are stochastic, involves a comparison of the cash flows generated by capital with the level of investment. Its application to the United States economy and the economies of other major OECD nations suggests that they are dynamically efficient.

Abstract: Standard transaction cost economics (TCE) considers transactions from the perspective of static efficiency. Increasingly, attention is required to dynamic efficiency; to capabilities to exploit transaction relations for innovation. Since innovation is dependent on knowledge and learning, the step from the statics to the dynamics of exchange requires and understanding of the development and acquisition of knowledge, preferences, and meaning, and the role in that of interaction between transaction partners. As a step towards this, the article provides an exploration of theories of knowledge and knowledge development, the relation to language, the role of intersubjective relations, the connection with evolutionary theory and the implications for transaction cost theory.

Abstract: The Kyoto Protocol is stimulating the development of emissions-trading schemes at the national and international levels. These are being introduced alongside existing policy instruments such as carbon taxes and negotiated agreements, leading to complex problems of policy interaction. But the topic of policy interaction remains under-researched. This paper aims to improve understanding of such interactions by examining the conditions under which a cap-and-trade scheme for carbon-dioxide emissions may usefully coexist with carbon/energy taxes, support mechanisms for renewable electricity, and policies to promote energy efficiency. The paper argues that each of these instrument combinations may be acceptable, provided they contribute to either improving the static or dynamic efficiency of the trading scheme, or delivering other valued policy objectives. But, since the coexisting instruments may raise overall abatement costs while contributing nothing further to emission reductions, the objectives and trade-offs within the policy mix must be explicit.

Abstract: This book is intended to help regulators learn about the tools needed to measure efficiency. It is based on lecture notes from courses the World Bank Institute offers in English, French and Spanish throughout the developing world and has benefited from feedback received during those courses. It provides an overview of the various dimensions of efficiency that regulators should be concerned with. It also summarizes the main quantification techniques available to facilitate decisions in the most common regulatory processes. The issues covered should be of particular interest to those policymakers and regulators interested in measuring relative efficiency and in implementing any incentive-based regulatory mechanism that requires the measurement of efficiency, such as price caps, revenue caps, or yardstick competition. The book focuses on methodology selection, data collection, and related issues. It provides readers with all the conceptual tools they need to make real-life decisions. It is also supported by a web site from which readers can download software they can use to implement the techniques described.
