Hi Rickooreo,Your reasoning would be airtight
if the case study told us
why taxpayers chose Swedish stocks. The catch is what counts as a valid selection here.
Look again at the exact wording in the
Case Study tab:
"Reports available to taxpayers showed that Swedish stock prices had been rising rapidly, and as a result a large proportion of taxpayers invested heavily in Swedish stocks."That phrase
"as a result" hands you the cause outright - the recent, prominent rising-price reports. That's the
availability bias described in the first tab. The case study never says taxpayers picked Swedish stocks
because they were Swedish / familiar.
Where your logic slips: the question asks you to select "Contributed significantly" only when the information
clearly indicates it. Home bias would
fit the pattern (they did concentrate in home-nation stocks) - but fitting a definition is not the same as being clearly indicated as a cause. The concentration is already fully explained by the rising-price reports. So whether familiarity added anything on top is
indeterminate - not established.
A good tell: Question
3 asks what
extra fact would be needed to show familiarity bias was at work. If home bias were already clearly demonstrated, that question wouldn't need to exist.
A tiny stand-in to feel the difference:Fact: "A café put a huge 'FRESH DONUTS' sign in the window, and as a result most customers bought donuts."
Did customers buy donuts because they
love donuts (a standing preference)? Maybe - but the sentence only tells you the
sign drove the purchase. The preference is possible but
not indicated.
Same move here: the reports (the sign) are the stated cause; home-nation familiarity (the standing preference) is unconfirmed. That's why Home Bias is
Did not contribute significantly / indeterminate.
Answer: Contributed Significantly, Did not contribute significantly/indeterminate, Did not contribute significantly/indeterminateRickooreo
Doubt in Q1
2. Home bias Contributed significantly
Definition: Investors irrationally prefer investments from their home country.
Case:
Taxpayers invested heavily in Swedish stocks.
The default instead was globally diversified.
Concentrating in Sweden rather than diversifying contributed to poorer performance.
Thus I selected contributed significantly
