Applying compare and contrast to trade and exchange-rate scenarios

Every paper's Excellence part asks you to compare TWO specific, named groups — the skill of correctly identifying how the SAME change affects each group differently, in opposite or different ways.

The structure of a strong compare-and-contrast answer

  • Identify what specifically CONNECTS the two named groups to the change (e.g. tourists buy foreign currency; importers also need foreign currency, but for a different purpose).
  • Trace the EFFECT on group one fully, with the direction (better off / worse off) stated explicitly.
  • Trace the EFFECT on group two fully, ALSO with the direction stated explicitly — even if it seems similar to group one, state it separately.
  • End with the CONTRAST: are the two groups affected in the SAME direction (both gain, both lose) or OPPOSITE directions — and why the mechanism produces that specific pattern.
Worked example Comparing NZ tourists visiting the USA and NZ businesses importing US goods, after a depreciation The NZD depreciates against the USD. Compare and contrast the impact on NZ tourists visiting the USA and NZ businesses importing consumer products from the USA. CONNECTION: both groups need to exchange NZD for USD to make a purchase — tourists for spending money, businesses for paying suppliers. TOURISTS: a depreciated NZD buys FEWER US dollars, so the SAME trip now costs more in NZD terms — tourists are WORSE OFF, facing higher effective holiday costs. IMPORTING BUSINESSES: the same depreciated NZD means importing businesses must pay MORE NZD to buy the same quantity of US goods — also WORSE OFF, facing higher input costs. CONTRAST: both groups are affected in the SAME direction (worse off) by the SAME mechanism (a weaker NZD buying less foreign currency) — the depreciation that helps NZ exporters hurts both of these NZD-to-USD converting groups equally. ✓ Recognising that both groups are hurt by the SAME mechanism, rather than assuming a comparison must always produce a winner and a loser, is the sophisticated move — sometimes the "contrast" is that there is NO contrast in direction, only in the specific cost each group bears. ✕

Assuming a compare-and-contrast question must always produce one winner and one loser

Not every comparison splits into a winner and a loser — sometimes (as with tourists and importers both facing a weaker NZD) BOTH named groups are affected in the SAME direction. Forcing an artificial "winner vs loser" framing when the true answer is "both worse off, for related reasons" misrepresents the actual economics.
Pairing type seen in past papersTypical direction pattern
Producers vs consumers of the same goodUsually opposite directions
Tourists vs importers (same currency move)Often the SAME direction
One industry's workers vs another'sDepends on which industry gains the resources
