巨无霸指数,购买力的另类指标

 

自从Economist发表Big-Mac Index(巨无霸指数?)之后,宏观经济学中产生了一个新流派:Burgernomics。(汉堡经济学?)

 

这种用麦当劳的Big-Mac来衡量各个国家购买力水平的流派深受欢迎。在这个GDP被引申为“Gross Deceptive Product”的时代,Big-Mac Index无疑成为了更实际更大众的指标。

 

那就用Burgernomics来比较一下之前计算的新加坡和中国购买力情况。

 

—————————————————————

 

新加坡

 

Big-Mac售价 SGD 4.25

 

中国

 

巨无霸售价 RMB 10.5

 

也就是说,Big-Mac Index下计算出来的购买力平价汇率为 SGD:RMB = 2.47。

 

这个结果和之前用GDP per capita PPP计算出来的 2.51 的结果惊人吻合!

 

伟大的自然!

在中国每月赚多少钱才和新加坡消费水平相当?

 

眼看这段时间坡币汇率急跌,买也不是卖也不是,坐立不安。干脆来算一下新加坡年收入2万坡币到底和国内年收入多少人民币的消费水平一样。

 

数据来源:Wikipedia

--------------------------------

 

新加坡

Nominal GDP per capita:      USD 35162 (2007 estimate)

GDP per capita PPP:             USD 49754 (2007 estimate)

计算出购买力乘数:             49754 / 35162 = 1.415

 

中国

Nominal GDP per capita:      USD 2034 (2007)

GDP per capita PPP:              USD 5300 (2007)

计算出购买力乘数:             5300 / 2034 = 2.606

 

得出中国购买力乘数为新加坡购买力乘数的 2.606 / 1.415 = 1.84倍。

 

取当前汇率中间价 SGD:RMB = 4.62

 

实际算入购买力乘数的汇率为 4.62 / 1.84 = 2.51

 

也就是说,新加坡年收入2万坡币的消费水平和中国年收入5.02万人民币的消费水平相当。

 

当然,由于伟大的中国实在太大,深圳和成都的数据可能有很大的差距。而且数据的真实性也存疑。

不过就这个计算结果看来,我个人感觉基本和中国新加坡两地城市生活挂钩了。

 

PS。 新加坡年收入2万新币真的是低收入了。唉,为了生活,真不容易。

Buy American, 恐慌与贪婪之间

 

转载一篇10月16日沃伦·巴菲特发表在纽约时报的观点文章:《Buy American. I am.》

---------------------------------------------------


THE financial world is a mess, both in the United States and abroad. Its problems, moreover, have been leaking into the general economy, and the leaks are now turning into a gusher. In the near term, unemployment will rise, business activity will falter and headlines will continue to be scary.

So ... I’ve been buying American stocks. This is my personal account I’m talking about, in which I previously owned nothing but United States government bonds. (This description leaves aside my Berkshire Hathaway holdings, which are all committed to philanthropy.) If prices keep looking attractive, my non-Berkshire net worth will soon be 100 percent in United States equities.

Why?

A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful. And most certainly, fear is now widespread, gripping even seasoned investors. To be sure, investors are right to be wary of highly leveraged entities or businesses in weak competitive positions. But fears regarding the long-term prosperity of the nation’s many sound companies make no sense. These businesses will indeed suffer earnings hiccups, as they always have. But most major companies will be setting new profit records 5, 10 and 20 years from now.

Let me be clear on one point: I can’t predict the short-term movements of the stock market. I haven’t the faintest idea as to whether stocks will be higher or lower a month — or a year — from now. What is likely, however, is that the market will move higher, perhaps substantially so, well before either sentiment or the economy turns up. So if you wait for the robins, spring will be over.

A little history here: During the Depression, the Dow hit its low, 41, on July 8, 1932. Economic conditions, though, kept deteriorating until Franklin D. Roosevelt took office in March 1933. By that time, the market had already advanced 30 percent. Or think back to the early days of World War II, when things were going badly for the United States in Europe and the Pacific. The market hit bottom in April 1942, well before Allied fortunes turned. Again, in the early 1980s, the time to buy stocks was when inflation raged and the economy was in the tank. In short, bad news is an investor’s best friend. It lets you buy a slice of America’s future at a marked-down price.

Over the long term, the stock market news will be good. In the 20th century, the United States endured two world wars and other traumatic and expensive military conflicts; the Depression; a dozen or so recessions and financial panics; oil shocks; a flu epidemic; and the resignation of a disgraced president. Yet the Dow rose from 66 to 11,497.

You might think it would have been impossible for an investor to lose money during a century marked by such an extraordinary gain. But some investors did. The hapless ones bought stocks only when they felt comfort in doing so and then proceeded to sell when the headlines made them queasy.

Today people who hold cash equivalents feel comfortable. They shouldn’t. They have opted for a terrible long-term asset, one that pays virtually nothing and is certain to depreciate in value. Indeed, the policies that government will follow in its efforts to alleviate the current crisis will probably prove inflationary and therefore accelerate declines in the real value of cash accounts.

Equities will almost certainly outperform cash over the next decade, probably by a substantial degree. Those investors who cling now to cash are betting they can efficiently time their move away from it later. In waiting for the comfort of good news, they are ignoring Wayne Gretzky’s advice: “I skate to where the puck is going to be, not to where it has been.”

I don’t like to opine on the stock market, and again I emphasize that I have no idea what the market will do in the short term. Nevertheless, I’ll follow the lead of a restaurant that opened in an empty bank building and then advertised: “Put your mouth where your money was.” Today my money and my mouth both say equities.

-------------------------------------------------

以下是一点个人看法

市场真的恐慌了吗?这种没有标杆的判断需要的是经验与直觉。从这点上看来,没有任何理由能够怀疑78岁的巴菲特。在别人恐慌时贪婪,这个道理总是很简单,要做起来却很难,Simple but not Easy。

目前看来金融危机还没有全面影响到实体经济,应该贪婪的可能仅仅是美国的一些银行股,比如巴菲特在本月初已经开始买入一些Wells Fargo。

另外强调一点大众的群体无意识,他们在得知巴菲特的Berkshire Hathaway的子公司Mid American出资18亿港元买入比亚迪电子股份之后疯狂购买比亚迪,而忽略了18亿港币仅是巴菲特投资组合中非常小的份额。同样荒谬的是,去年的无脑大众可以在巴菲特12港元卖出所有中石油股份之后以48人民币价格疯狂买入。这就是真实的市场!这样看来,现在的中国股市还没有到恐慌的时候,因为在75美元一桶的油价,中石油还要卖12人民币!

这篇《Buy American. I am.》也许将来又会成为一段历史的见证。

今年的诺贝尔经济学奖和新加坡经济的劣势

 

10月14日的《21世纪经济报道》头版有篇文章“危机预言者克鲁格曼的纠偏构想”,提到了这位今年经济学诺奖得主Paul Krugman曾经在其1994年著作《亚洲奇迹之谜》中指出东南亚经济“缺乏技术含量”,实为“纸老虎”,并且预言了97年的亚洲金融危机。

 

预测金融危机这件事可以当作闲话,但是东南亚经济是纸老虎却丝毫不假。作为一个国家形式的经济体而言,新加坡就是很典型的低档水平。从当前新加坡统计局的资料可以看到,称为第三产业的服务行业占据了整个2400亿新元GDP的三分之二,两倍于工业GDP。在这场全球泡沫破裂的盛宴中,工业硬实力低下的经济体必然遭受严重损失。创设财富的蒸发,欧洲美国大规模救市引发的货币隐患,都能够从根本上动摇仅有480万人口的新加坡整体经济。虽然制造业为GDP贡献了570亿,但是相比于1570亿的整个服务业,完全是毫无抵御能力的小树苗。2008年第二季度的统计数据已经显示出新加坡的经济衰退迹象。转而看中国总体经济,一二三产业的比例约为13:46:41,在内需正常的状态下对全球风险的抵抗能力就明显不同了。用一点简单的比喻,假设全球经济是个池塘,各个国家是浮在水面的鸭子,池塘水位高低变化,新加坡这只鸭子也上上下下,而中国这只鸭子还能拍拍翅膀。

 

 
有数据显示说新加坡和香港由于转口贸易发达,每年的进出口总额是GDP的一到两倍,因此抵抗国际金融风险能力非常低下。

转帖:扁鹊见蔡桓公(《史记 股民列传 》)

 

扁鹊见蔡桓公,立有间,扁鹊曰:“股市将大跌,不抛将恐回吐利润。”桓侯回:“寡人不抛。”扁鹊出,桓候曰:“空头之好测顶以为神。”居十日,扁鹊复见,曰:“股市将大跌,不抛将恐损失手续费”桓侯不应。扁鹊出,桓俟又不悦。居十日,扁鹊复见,曰:“股市将大跌,不抛将恐套牢。”桓侯又不应。扁鹊出,桓候又不悦。 居十日,扁鹊望桓侯而还走。居五日,股市果大跌,桓侯忙拨扁鹊手机,回应曰:您呼叫的用户已关机,请稍候再拨。桓侯遂套牢。(《韩非子》)
    
    太史公曰:天下股民,蔡桓公者十之八九;扁鹊者十之一二也。
