Diamonds Are a Rebel's Best Friend

Many countries that produce rough diamonds have experienced a highly adverse pattern of economic development. In this article, we propose that the primary reason for the negative impact is that diamonds easily become the prize in predatory struggles between loot‐seeking rebels and more or less kleptocratic governments. In weakly institutionalised countries like Angola, the Democratic Republic of Congo and Sierra Leone, this theory works well, but it does not explain the impressive growth record of diamond‐rich Botswana and Namibia. For a deeper understanding of these countries’ success, we point at the crucial differences between kimberlite and alluvial mining and the effect of having the world‐leading firm De Beers as a partner. Indeed, we argue that in countries like Angola, diamonds can never be a major vehicle for sustained growth, although the ongoing Kimberley process for eliminating conflict diamonds probably has contributed to making several African countries more stable.     

On the democratic legacy of colonialism

The article features a temporal approach to analyzing the impact of Western colonialism on contemporary levels of democracy. We present a new data set with dates of colonization, independence, and a colonizing event for all former colonies and dependencies that are regarded as countries today (143 observations). Our data, as well as the existing literature, suggest that the very heterogeneous era of colonization should be divided into an early ‘mercantilist’ wave and a much later ‘imperialist’ wave with quite different characteristics. We show that there is a strong positive effect of colonial duration on democracy, an effect which turns out to be driven primarily by former British colonies and by countries colonized during the imperialist era.

The economic costs of biological predation

This paper developes a bioeconomic model to analyse the economic losses from the reduced harvesting of prey species resulting from an increase in the stock of a natural predator. Examples of large mammals creating economic damage are whales and African elephants. The economic losses depend critically on the actual management of the prey stock, although the three measures we develop are equal when the stock is managed so as to maximize the sustained economic rent from the prey species. Predation losses are illustrated by the case of the Northeastern Atlantic Minke whale, where the estimate of the average predation cost per whale in 1991–1992 is between $US 1780 and $US 2370, using Norwegian cost and earnings data. A ten percent stock increase is estimated to cause a loss of almost $US 19 million to the fishers of the prey species. If half of this cost were assigned to Norway it would be equivalent to 2.8 and 6.7 percent of the gross profits of the Norwegian cod and herring fisheries, respectively.     

Revising price history: consumer price index for Norway 1492–2018

ABSTRACT

The paper presents a new combined annual cost of living and consumer price index for Norway covering 1492–2018, indicating that Norwegian price history has to be revised. The new historical price index is constructed on a significantly richer data material, which also makes it cover a longer period of price history than the existing one. This is made possible by the compilation of quantitative data from numerous sources, mostly originating from the eighteenth, nineteenth and early twentieth centuries, with grain prices stretching back to 1492. The new combined cost of living and consumer price index is constructed by a Laspeyres approach with shifting baskets for commodities and expenditure groups.

The index makes it possible to follow annual inflation and deflation in Norway for a period of 526 years. When comparing to existing indices, the new series reveals that revisions are needed in Norwegian price history. These make the historical price development more in line with those of the neighbouring countries and more in line with the pattern of wholesale prices.
