- We use daily data to examine price responses in the Swedish gasoline market to changes in the Rotterdam spot price, exchange rates and taxes. The distribution of price adjustments by a leading retail chain, for the period January 1980 to December 1996, is symmetric with no small adjustments. An error correction model shows that, in the short run, prices gradually move towards the long-run equilibrium in response to cost shocks. There is some evidence that, also in the short run, prices are stickier downwards than upwards. Prices respond more rapidly to exchange rate movements than to the spot market price. Our analysis emphasizes that to fully understand price adjustments it is necessary to examine data sets where the sample frequency at least matches that of price adjustments.

- BACKGROUND AND PURPOSE: The aim of the present study was to examine resource utilization during a 12-month period after acute stroke in elderly patients randomized to care in an acute stroke unit integrated with a care continuum compared with conventional care in general medical wards. A secondary aim was to describe costs related to the severity of stroke. METHODS: Two hundred forty-nine consecutive patients aged >/=70 years with acute stroke within 7 days before admission, living in their own homes in Göteborg, Sweden, without recognized need of care were randomized to 2 groups: 166 patients were assigned to nonintensive stroke unit care with a care continuum, and 83 patients were assigned to conventional care. There was no difference in mortality or the proportion of patients living at home after 1 year. Main outcomes were costs from inpatient care, outpatient care, and informal care. RESULTS: Mean annual cost per patient was 170, 000 Swedish crowns (SEK) (equivalent to $25,373) and 191,000 SEK ($28,507) in the stroke unit and the general medical ward groups, respectively (P:=NS). Seventy percent of the total cost was for inpatient care, and 30% was for outpatient and informal care. For patients with mild, moderate, and severe stroke, the mean annual costs per patient were 107,000 SEK ($15,970), 263,000 SEK ($39, 254), and 220,000 SEK ($32,836), respectively (P:<0.001). There was no statistical difference in age or nonstroke diagnosis. CONCLUSIONS: The total costs the first year did not differ significantly between the treatment groups in this prospective study. The total annual cost per patient showed a very large variation, which was related to stroke severity at onset and not to age or nonstroke diagnoses. Costs other than those for hospital care constituted a substantial fraction of total costs and must be taken into account when organizing the management of stroke patients. The high variability in costs necessitates a larger study to assess long-term cost effectiveness.

Knowledge Interests in Corporate Environmental Management
- 2001

- We know from earlier studies that corporate environmental management is a young discipline, not yet integrated in general management and organization studies, but that researchers take an increasing part in the ongoing scientific conversation. However, the underlying knowledge interests characterizing the field of corporate environmental management is yet empirically unsubstantiated. One way to find out what elements make up the field is to analyse the contents of the most influential writings in the field. The present article identifies the 10 most cited works in Business Strategy and the Environment in 1992–2000 and explores the content of these texts. We conceptualise a typology for analysing corporate environmental management theory and formulate a characterization of the dominating knowledge interests. Our findings show that the theoretical fundament of corporate environmental management lacks a hermeneutic knowledge interest.

The Growth and Welfare Effects of International Mass Migration
- 2002

Ingår i: Journal of International Economics. - : Elsevier B.V. ; 56:1, s. 177-204

Tidskriftsartikel (refereegranskat)abstract
- We analyze the effects of immigration quotas on growth and welfare in North-South version of the quality ladders growth model. Quotas in the North increase the growth rate. However, they lower the static utility level and the discounted welfare of Northern workers. Also the discounted welfare of asset owners drops. Hence, unlike in the static migration model where the representative agent in the host country benefits from immigration, in our dynamic model, the representative agent loses despite a positive growth effect. Winners from immigration quotas are the immigrants and the remaining workers in the South.
