moreSince the announcement, in 2007, of the pre-salt oil layer by the Brazilian Oil Company (Petrobras), there has been a lot of optimism about Brazil’s future economic development. Even before any extraction has been started off, pre-salt revenues have already been legally addressed to fund country-wide educational and health systems. Nevertheless, on one hand, the country formally subscribes to international negotiations on climate change to curb fossil fuel emissions; on the other hand, even though claiming to bear a clean energy matrix, it falls back on its newest oil reserves to support its future economic development. Nowadays, though, many leading economic countries have heavily invested in renewable rather than in fossil fuel energy sources. Moreover, alternative fossil options, such as shale gas, have become economically and technologically feasible. So, in this international context, is the ownership of a large oil reserve a blessing or a curse? The answer is given by a non-renewable resource multi-period model (Hotelling model). By drawing an optimal depletion price path along which extraction revenues would not dramatically rise or fall in response to a non-optimal programme, its objective is to prevent the “Dutch disease” and distortions in the oil volume to be eventually shared between the pre-salt reserve owner (government) and its exploiting companies. If market prices are higher than the optimal ones, the primary commodity is likely to be over-depleted and largely exported, thereby causing the exchange rate to over-appreciate and the demand for foreign, instead of domestic, goods to increase. Nonetheless, results show that optimal prices, quantities and economic lifetime of the resource critically rely on current estimates for the existing stock, oil prices and interest rates.
