Hall's (1988) approach to study price- cost margins is adapted to simultaneously estimate price- cost margins and scale economies from a panel of plant level data. The paper shows how this methodology provides a very flexible framework with only a few, economically interesting parameters to be...

This paper investigates the determinants of Norwegian import prices of manufactures over the period 1970(1) - 1991(4). Multivariate cointegration analysis establishes a long-run relationship between import prices, foreign prices, the exchange rate and domestic unit labour costs. Normalized on...

This article uses the Case-Shiller technique for constructing housing price indices on a Norwegian data set of transactions for the period 1991-2002 consisting of 10 376 pairs of repeated sales. Using a weighted least squares scheme in order to control for heteroskedasticity, we construct a...

In order to analyse the consequences of uncertainty for prices and efficiency in a hydropower system, we apply a two-period model with uncertainty in water inflow. We study three different market structures, perfect competition, monopoly and oligopoly and stress the importance of the shape of...

This descriptive study discusses the effects of increases in domestic gas prices on the Russian gas market. Domestic natural gas prices have remained below their long-run marginal cost for more than a decade since Russia's movement toward a market economy in 1991. As a result, the ability of the...

We investigate the applicability of the present-value asset pricing model to fishing quota markets by applying instrumental variable panel data estimation techniques to 15 years of market transactions from New Zealand’s individual fishing quota market. In addition to the influence of current...

Individual fishery quotas (IFQs) are an increasingly prevalent form of fishery management around the world, with more than 170 species currently managed with IFQs. Yet, because of the difficulties in matching quota holdings with catches, many argue that IFQs are not appropriate for multispecies...

Fisheries worldwide continue to suffer from the negative consequences of open access. In 1986, New Zealand responded by establishing an individual transferable quota (ITQ) system that by 1998 included 33 species and more than 150 markets for fishing quotas. We assess these markets in terms of...

We study the effects of various environmental regulations on environmental performance measured as emission intensity. Moreover, we aim to test whether any such effects are persistent or only temporary. Conventional theory predicts that indirect regulations as opposed to direct regulations...

The present paper investigates effects of regulatory inspections on compliance and emissions of energy intensive manufacturing plants in Norway. The regression analysis shows that increased probability of inspection reduces the probability of violation. This is in line with previous studies, and...
