We consider a sovereign wealth fund that invests broadly in the international financial markets. The influx to the fund has stopped. We adopt the life cycle model and demonstrate that the optimal spending rate from the fund is significantly less than the fund’s expected real rate of return. The optimal spending rate ensures that the fund will last “forever”. Spending the expected return will deplete the fund with probability one. Moreover, this strategy is inconsistent with optimal portfolio choice. Our results are contrary to the idea that it is sustainable to spend the expected return of a sovereign wealth fund.

In order to extract lycopene more effectively, this experiment focused on the optimization of ethanol pretreatment method to study the effects of ethanol treatment on the extraction rate of lycopene and its antioxidant activity. The test results show that 2 times ethanol treatment is very effective for improving lycopene yield. The optimum conditions of ethanol treatment are temperature 50 ℃, treatment time 1 time 2h, 2 times 2h, solid to liquid ratio is 1:12. The lycopene yield can be reached 20mg / 100g above.

Oil-rich countries have oftentimes been confronted with the challenge of diversifying their economies away from oil dependence given the exhaustible nature of these fossil fuels. Investing in sovereign wealth funds has been one of the most ubiquitous ways of preparing for the post-oil period. Investing in sovereign wealth funds rather than directly injecting the oil revenues in the economy not only precludes the outbreak of the Dutch Disease (which is known for giving rise to an exchange rate appreciation, crowding out non-oil industries and keeping the economy reliant on oil), but it also saves for future generations. Yet, in the case of Azerbaijan, the Sovereign Wealth Fund of Azerbaijan (SOFAZ), founded in 1999, has only increased this reliance on oil. Using the rentier states theoretical framework, this paper will argue that the direct control over SOFAZ exercised by the president and the lack of consultation with the NGOs have made corruption easier, making the task of economic diversification more difficult. This has been possible because through corruption the president has often resorted to oil money to buy peace rather than invest it in economic diversification. As a result, since the foundation of SOFAZ, the country is more reliant, not less, on oil.   Full text available at: https://doi.org/10.22215/rera.v8i1.223
