Bergen: a Norwegian Big Mac in the country's second-largest city
Bergen's Big Mac price runs slightly below Oslo's — reflecting the absence of capital-city premium but still well above any non-Swiss European city. Bergen is Norway's second-largest city, anchored by the maritime, fisheries, and offshore oil-services sectors. Its real wages are at developed-market levels, but its commercial rent base is more moderate than Oslo's.
For Big Mac Index analysts, Bergen serves as the comparator that surfaces Oslo's capital premium. The Oslo-Bergen spread is narrower than most country's capital-versus-second-city spreads, because Norwegian wages compress at the high end — there's only so much "premium" that can stack on top of an already-high baseline. Watch the spread for signs that Oslo's professional-services employment is pulling further ahead of Bergen's industrial base; when the gap widens, sectoral bifurcation is the story.
