Let's see: What Dr. Khan describes as "a patient in intensive care unit fighting desperately for survival" you describe as capable of running a marathon the next day, since "things are not bad as they seem". Uh-huh. Right.
"Growing gap between dismal official economic statistics and consumption boom .... is a challenge for many analysts....."
You are correct that the economy is not doing well. And the other fellow is also correct that conspicuous consumption is booming.
At first glance, this appears to be a paradox that puzzles everybody: the headline numbers indicate an economy in an abysmal state, but everywhere one looks, there are people shopping like there is no tomorrow.
So how is this possible?
ANSWER: There is no paradox. The answer is not at all surprising.
We do not need to look for complicated explanations in the shadows of reality like informal economy, underground consumption, over-invoicing of imports, under-invoicing of exports et cetera.
The explanation is a whole lot simpler than that.
To see how this works, go to the finance ministry:
http://www.finance.gov.pk/survey/chapter_12/01-GrowthAndStabilization.pdf
Look at Table 1.4 on Page 9 to see the "Composition of GDP Growth":
GDP = Consume + Invest + Exp-Imp
4.2% = 9.4% + (-1.4%) + (-3.8%)
Now we can see how obvious and unsurprising the answer to that "riddle" is. The gung-ho consumption we see (1st term on RHS) is simply coming at the cost of falling investment (2nd term on RHS)and at the cost of frittering away the remittances through consumptive net-imports (3rd term on RHS). Note the spectacular performance of Consumption (9.4% growth) in the context of the relatively dismal performance of GDP (4.2% growth on LHS).
Okay, we go next to Table I.4 in the APPENDIX and see "EXPENDITURE ON GROSS NATIONAL PRODUCT AT CONSTANT PRICES".
A) Look at the dramatic rise (in constant 2000 prices, i.e. no inflation) of:
1) Private Consumption Expenditure
2) General Govt. Current Consumption Expenditure
3) Import of Goods and Non-Factor Services
B) Then look at the collapse (in constant 2000 prices, i.e. no inflation) of:
1) Gross Domestic Fixed Capital Formation
2) Export of Goods and Non-Factor Services
C) Then look at the modest change (in constant 2000 prices, i.e. no inflation) of:
1) Expenditure on GDP at Market Prices
Again we can see how obvious and unsurprising the answer to that "challenging riddle" really is. Again we note the same implication. The gung-ho consumption we see (A1 & A2 terms) is coming at the cost of falling investment (B1 term) and at the cost of frittering away the remittances through consumptive net-imports (B2-A3). The GDP numbers in C(1) are still dismal.
SUMMARY: The boom in conspicuous consumption is coming at the expense of saving & investment. There is no miracle here. Just misguided people frittering away their seed-corn. The consumption boom we are witnessing is not sustainable and always ends in the same way: Financial Crisis, BOP crisis, Currency crisis, Total Macroeconomic Collapse.
