ourage subtler forms of protectionism LISTEN to the campaign rhetoric of America s victorious senators and congressmen (not recommended), and you might easily conclude that bashing trade wins votes. Politically, the calculation looks easy. The benefits from freer trade are diffuse and the winners do not always know in advance who they are. On the other hand, sheltered industries know precisely how much they stand to lose if left bare and unaccommodated. But look further afield and the affinity between open politics and open markets seems clear. As use of the ballot box has spread, especially to poorer parts of the world, tariffs have fallen. In 1981, for example, the world had only about 40 democracies; and the average fuel dispenser tariff in developing countries was almost 30%. By 2003 the roll call of democracies had more than doubled and tariffs had fuel dispenser fallen by more than half. Why? For one thing, voters are also consumers who do not like paying extra for imported goods. Democratic governments can withstand some consumer disgruntlement, especially if it is too thinly spread to swing many votes. But autocracies need pay it no heed whatsoever. Voters are also workers. The poor countries, where many of the new democracies have flowered, are typically endowed with abundant labour but scarce capital. If they cut themselves off from trade, manpower will be cheap relative to capital. The plutocrats who profit from this economic isolation are the natural allies of autocratic government. Democracy, by contrast, enfranchises a wider circle of people who stand to gain from selling their labour at something closer to world prices. For both of these reasons, freer trade often follows freer elections. One recent estimate found that a transition from airtight autocracy to full-throated democracy (in a hypothetical developing country of average size, income, and so on) yields a fall in tariffs of seven percentage points, from about 22% to 15% or so. Indeed, Daniel Kono, of the University of California at Davis, fuel dispenser
