Stricter environmental regulations (e.g. the EU’s Water Framework Directive) will entail many environmental improvement measures in waters that have been affected by hydropower, and dam removals are becoming a more common measure. This paper reviews economic evaluations of dam removals, primarily drawing on studies in the USA, and identifies key, frequently recurring, issues that future evaluations will likely need to consider. The paper also reports on an ex-ante evaluation of the recent removal of the Marieberg Hydropower Plant in the Mörrum River in Sweden. An environmental valuation survey carried out as a key part of this evaluation was conducted as a replication of a previous study, where the policy context was different but the expected ecological outcome similar. The replication study produced comparable results to those of the previous study.

This paper estimates resource rents for Mozambican coal mining using company-level data employing the residual value method devised by SEEA-Energy (the multi-purpose conceptual framework for organising energy-related statistics) and compares the findings with the World Bank's estimates of coal rents. The latter estimates are often used in the resource curse literature and also guide the World Bank's policy notes, forming the baseline of their policy advice on resource exploitation. On average, the results show unit coal rents for the 2011–2020 period that are less than half of the World Bank estimates, suggesting that the World Bank overstates coal rents for Mozambique considerably. The main driver of this discrepancy is the World Bank's underestimation of extraction costs. The results suggest that studies employing resource rent estimates should consider sensitivity analyses and greater use of local data, and that the World Bank's policy advice should be interpreted cautiously to avoid unreasonably high expectations.

Economic theory on sustainable development suggests that resource-rich countries should reinvest the rents from natural resource extraction in other forms of capital to ensure that future consumption level of the economy can be greater than or at least equal to the level of their current consumption. Several seminal papers in the early 2000s indicated that the correlation between genuine savings and future consumption was weaker than theory predicted, at least when genuine savings were measured using the World Bank estimates. This paper revisits the issue and replicates two of these earlier studies to see whether the correlation has become stronger over time, on the back of policy changes in resource-rich countries and of revisions to the World Bank estimates. The results indicate that the correlation between genuine savings and future consumption growth may be stronger for poorer countries than for richer, and for sub-Saharan Africa, the theoretical predictions appear to hold.

Many rural forest dependents are still poor and exposed to food insecurity. Hence, this paper aims to study the linkage between forests and household food security by analysing factors that determine participation in forest activities and by examining differences between participants and non-participants in respect of the food-security outcome. The study was conducted in rural areas of the Shinyanga Region in Tanzania using cross-sectional data on a sample of 303 rural households. Marginal effects predicted that distance to the forest concerned, illness or death of a household member, and off-farm activities determined participation in forest activities. Propensity score matching revealed that those who participated in forest activities were less food secure than non-participants with comparable characteristics were, which supports the contention that rural forest dependents are prone to food insecurity. Government policy should, therefore, aim at enhancing alternative sources of income as well as food storage facilities and food production for rural households.

We estimate monetary values for switching costs in the Swedish market for electricity for private householdconsumers, using two different numerical methods. The electricity providers in Sweden with over 1 per cent marketshare were studied. Switching costs were estimated to be between 50 per cent and 95 per cent of yearly costs forelectricity. Considering that the electricity retail market was deregulated more than 20 years ago, and that the Swedishgovernment continues to facilitate switching for consumers, it is noteworthy that switching costs are still this high.Given that electricity is a homogeneous product where switching costs are mainly due to transaction costs andpsychological barriers to switching, it seems likely that switching costs may be even higher in other markets wherethere are additional barriers to switching. 

Denna rapport är ett underlag till miljökonsekvensbeskrivningen för Eystrasaltprojektet och studerar vindkraftparkens inverkan på det svenska och finska yrkesfisket. Detta görs dels i termer av effekter på nationell ekonomisk aktivitet (förädlingsvärde och sysselsättning), och dels i termer av påverkan på enskilda fiskares situation (tillgång till fångstområden och påverkan på lönsamhet).
