你的逻辑是用了以前的理论,并且没有empirical support的。现在的empirical在job
creation上面已经很清晰了,一个是说job creation和firm size成反比,另一个是说
firm size里面其实是start up才是产生job的。
你自己对literature不熟,也不愿意去看literature,还坚持自己以前学到的观点,估

【2019年1月9日的 1,200 个股票的短期谷底和高峰的预测】
熊市策略是逢高峰就卖空,谷底补空平仓,如此周而复始。要少做多。
熊市性质是多数日子前盘价位高,后盘价位低,如此制造下跌的趋势。
对比预测,如果股价越极端,散户获暴利的机会和风险其实反而越佳。
花街的捣蛋,挤空或砸价,其实是制造极端价供精明的散户收割暴利。
花街这么做绝非善意,而是要吓唬散户在其人为的极端价割肉出局。
花街有用之不尽的代理基金和资金充炮灰,可以任性的挤高峰砸谷底。
花街有别人的代理钱来任性,用大量炮灰钱可以买出涨价,砸出跌价。

dude, your point is plain wrong, despite the seemingly authoritative tone in
your statement.
within the AER (all electric range), a PHEV behaves just like a BEV.
actually, it can do slightly better than a BEV because it may has an extra
electric motor.

I test drove it on a weekend last month, it is overall a nice car, silent,

traditional look.
its AER is 87 miles per EPA rating. I bet you can get 100 miles if you drive
carefully (using regen, coasting, accel/deaccel smoothly). with the
occasional full charging (i.e. the "software" extender option), I believe
the real-life range can be anywhere between 110 to 130 miles for a careful

without knowing your budget, driving radius, and what you need that car for,
it is difficult to give a specific suggestion.
if this is your only car and you do need to frequently (>10%) go beyond 80
miles, you'd better get a plugin hybrid. volt is the best in this category (
AER, safety, build quality), however it has only 4 seats and is a bit more
expensive.

MPGe is based on energy density. it is not a simple addition. A volt has
98MPGe, 38 EPA AER with 38 MPGcs (MPG charge-sustaining)
F***Q

assuming T8's battery is on-par with other EV batteries, roughly 4miles/kWh,
then 25 AER translates into 6.25 kWh usable range out of the 9.2 kWh total
capacity (SoC=68%), then charging 6.25kWh with 12 hours on 110V is twice
slower than, for example, a volt (10 hours charging 11kWh out of 16.8kWh
capacity). This is similar with L2 charging.
unless the 9.2kWh number given by goVolvo was the usable range.

interesting ... I haven't paid attention to MPGe, but this makes sense.
however, EPS's numbers are underestimated for my driving habits. my car
achieves the EPS estimate (0.292*98*10.8=31 AER) only now when the outside
temperature drops below 0C.

finally, I measured the total charging power consumption using a kill-a-watt
. to charge a depleted battery to full for my volt drew 13kWh power from the
outlet. as my usable range now stables at 10.8kWh, that gives me a 83%
charging efficiency.
if I use this numbers, the EPA estimate becomes 0.0292*98*13=37.2 miles, I
guess that's where the 38 AER rating came from.

S.
if you can wait, volt gen2 is coming in July/Aug. 2015, which is said to
have 50+ miles AER (in CA, this means 60+ miles pure electric driving).
pricing is not known yet, but is said to be a few thousand lower than the
current volt.
if you can't wait, my recommendation is to go for a gen1 volt. you can
easily get 40-45 miles with electricity only in CA. however, if you are a
fan of BMW, then you may consider i3 with range extender.

those numbers are exaggerated because it was based on the Japanese JC08

price matters the most. the depreciation for the 70-90 AER BEV is expected
to go up as the 100-250 BEVs gradually become available (especially the
Chevy Bolt). so as long as your purchase price keeps the the potential
depreciation into consideration, you should be fine.
on the battery lifespan, you should not expect any major problem for a 6-yr
old BEV. manufacturers often offer 8 year 100k mile warranty. From the
