Right before an election, every government discovers a sudden, heartfelt passion for spending money. Roads that languished for a decade are paved in a month. Clinics announced years ago are suddenly opened with ribbon, scissors, and a camera crew. Wages are nudged up, fees are quietly frozen, and ministers who never visit the countryside develop a deep, dewy-eyed love of villages they cannot pronounce. The generosity is touching. It is also punctual.
This is not a hunch. It is one of the most thoroughly documented patterns in political economy, with a name that sounds far drier than the behaviour it describes: the political budget cycle. The idea goes back fifty years, to William Nordhaus and his 1975 model of the political business cycle, which argued that incumbents tune the economy to the electoral calendar rather than the other way round. Decades of data have since fleshed out the sketch. Spending that voters can see swells in the run-up to a vote, then is quietly tightened once the ballots are counted and the cameras have gone home.
Think of it as the pumpkin-spice latte of public finance. The seasonal blend is not an accident of supply; it is a product decision. It appears on schedule, engineered to be loved in the moment, wrapped in warm language and limited availability. Nobody pretends the pumpkin is the point. The point is the feeling, the timing, and the queue out the door. Campaign spending works the same way: wheeled out exactly when appetite peaks, formulated for maximum comfort, and conspicuously absent by the new fiscal year. You are not meant to ask what is in it. You are meant to enjoy it before it is gone.
And the data backs the menu. A study spanning ninety-one emerging and developing economies found that incumbent governments lift expenditure by roughly 1.75% of GDP in the year before a vote, with the sharpest rises in the most visible categories: infrastructure first, then social welfare and public services. Highways photograph better than balance sheets. A separate 2025 analysis of more than a hundred countries found that election-induced deficits rise about 0.6 percentage points of GDP in democracies and non-democracies alike. The seasonal release crosses every border and ideology.
Here is the part the marketing leaves out. The effect is statistically real, but often economically modest, and it is far stronger where the institutions meant to police it are weak. Where voters are well informed and the press can shout, the trick stops working; politicians who try it get caught. Research comparing why cycles differ across countries found that strong checks on executive power and an informed electorate shrink the manipulation toward nothing. Transparency is the off-season. It is precisely where institutions are thin that the flavour-of-the-month becomes a permanent fixture on the menu.
The genuinely expensive detail is what happens after the votes. The pre-election generosity is sold as a treat, but the bill does not vanish with the bunting. That 2025 study found the deterioration in deficits is not reversed after elections; the spending recedes only partly, while the debt it created stays put. Each cycle leaves the baseline a little higher than the last. The treat compounds. What looked like a one-off splurge becomes a structural habit, and the ratchet only turns one way: borrowing nudged up before each vote, never fully wound back once the applause dies down.
So the cost of short cycles is not the splurge itself, which is usually small. It is the slow accumulation, the way a recurring sugar rush rewrites a country’s long-term diet. Governments optimise for the next eighteen months because that is the horizon voters reward, and the horizon beyond it belongs to whoever is unlucky enough to be in office when the interest comes due. The seasonal blend tastes like care. It is, more often, a way of deferring the cost of care until someone else is holding the cup.
None of this requires villains. It requires incentives, a calendar, and an audience that responds to warmth more reliably than to spreadsheets. The fix is not to ban generosity but to make it legible all year round, so a road built in March looks no different from one built six weeks before a vote. Strong institutions are simply the rule that the menu must stay the same in every season.
Campaign promises, in the end, are seasonal blends: warm, sweet, and limited-edition, perfectly timed to the moment you are most willing to be charmed. Enjoy them while they last. Just remember that the bill for the flavouring arrives quietly, months later, long after the votes are counted and the cups have been cleared away.
