This paper concerns international coordination of environmental taxation. The main purpose is to study the global welfare effects that will arise, if there is an agreement between countries to slightly increase their emission taxes. We show that even if each individual country has chosen its...

This paper concerns green accounting in a global economy, which is characterized by transboundary environmental problems. The world is divided into two separate regions, and the regions differ substantially with respect to income per capita, emissions of greenhouse gases per capita, population...

In this paper, we introduce cost benefit rules for projects embedded in a stochastic optimal growth framework. We model uncertainty in terms of Brownian motion and Ito integrals. Taking the mathematical expectation of the project means that the Ito integrals vanish, and we end up with a cost...

This paper concerns public good provision under distortionary labor income taxation. The labor market is characterized by imperfect competition due to the influence of unions over wage formation. We show that a tradeoff between employment and hours of work per employee influences the welfare...

This note concerns the importance of habit formation for social accounting. With internal habit formation, earlier procedures for welfare measurement in the first best apply with minor modifications. This result strengthens the idea behind using the comprehensive net national product as a...

This paper concerns the welfare effects of public abatement projects, and concentrates on the influence of distortionary taxes and imperfect competition in the labor market. In addition to the direct environmental benefits and costs of resource use, abatement policies give rise to welfare...

Following the 1987 report by The World Commission on Environment and Development, the genuine saving has come to play a key role in the context of sustainable development, and the World Bank regularly publishes numbers for genuine saving on a national basis. However, these numbers are typically...

This paper studies how envelope theorems have been used in Economics, their history and also who first introduced them. The existing literature is full of them and the reason is that most families of optimal value functions can produce them. The paper is driven by curiosity, but hopefully it...

The existing literature is full of them and the reason is that all families of optimal value functions can produce them. The paper is driven by curiosity, but hopefully it will...

The concept of genuine saving appeared for the first time in a proof of a now well known theorem in Weitzman (1976). It was reinvented and used as a local welfare indicator by Pearce and Atkinson (1993). The purpose of this paper is to generalize this welfare measure to a stochastic Brownian...
