其中一段蠻有趣的：
The truth is more prosaic. Finding and developing new oil fields is an
expensive and time-consuming business. The giant new fields in the deep water
off Brazil are unlikely to produce oil for a decade or more. Furthermore, oil
is perverse. When prices are low, oil-rich countries welcome the low-cost,
high-tech and well-capitalised oil firms. When prices are high, countries
like Russia and Venezuela kick them out again. Likewise the engineers, survey
ships and seismic rigs that oil firms need to find and produce new deposits
are expensive right now. The costs of finding oil have, temporarily, doubled
precisely because everybody wants to give them work.
我想你沒仔細看文章說的...
The giant new fields in the deep water
off Brazil are unlikely to produce oil for a decade or more
這是指巴西的深海油田 不向過去 是幾年來的油田(成本)一樣
下面這一段 是原PO說好玩的部分
When prices are low, oil-rich countries welcome the low-cost,
high-tech and well-capitalised oil firms. When prices are high, countries
like Russia and Venezuela kick them out again
俄羅斯 和 委內瑞拉 在油價低的時候 歡迎 有高技術high-tech 低成本low-cost
以及 well-capitalised 的石油公司
但是在高價時 卻將他們kick out <<<也就是把生產有效率的公司 踢開...
這就是你所謂的政治經濟學???
Likewise the engineers, survey
ships and seismic rigs that oil firms need to find and produce new deposits
are expensive right now. The costs of finding oil have, temporarily, doubled
precisely because everybody wants to give them work.
上面這一段指的是 探勘原油的設備 工程師 因為需求的高漲 價錢在短時間
上漲兩倍 因為...谁都希望雇用他們工作...
原PO連結的那篇文章裡有寫到...原油的高漲...一個原因是2003年
投資在原油的資金 只有目前的1/20
Stuck for answers, politicians have been looking for scapegoats. Top of the
list are the speculators profiting from other people's hardship. Some $260
billion is invested in commodity funds, 20 times the level of 2003. Surely
all that hot money has supercharged the demand for oil?
