Why some economies stay poor. Strong answers identify which barrier actually binds for the economy in the question, rather than listing all of them.

Barriers to development

Concept explainer · 2 minDevelopment factors sorted into macro and microEconplusDalBuilt for the essay that asks what promotes development, and sorted so it can be recalled under pressure. On the macro side: growth, whether from trade liberalisation or foreign direct investment; infrastructure; government finances solid enough to fund health, education and welfare; a financial sector that supports investment and saving; diversification for balance; and policy aimed at the three pillars of education, health and infrastructure. The micro side then comes down to those specific markets working.

The resource curse

Counter-intuitively, abundant natural resources are frequently a barrier rather than an advantage, and knowing why is a strong evaluative asset.

The remedy most often cited is a sovereign wealth or stabilisation fund: save the windfall abroad, spend only the sustainable income from it, and thereby avoid both the appreciation and the boom-bust cycle. Norway is the standard example of the resource curse being avoided by design rather than luck.

The three gaps, told apart

"The poverty cycle" is often written as if it were one mechanism. It is more useful, and better rewarded, to separate the constraints, because each has a different remedy.

A strategy that closes one gap and not the others achieves little, which is the point that makes an evaluation in 4.10 work.

Why institutions sit underneath everything else

Institutional barriers deserve separating from the economic list rather than sitting inside it, because they determine whether any other policy can function.

Weak property rights mean an investor cannot be confident of keeping the returns, so investment does not happen at any interest rate. Weak contract enforcement means firms trade only with people they know, which caps the size of the market and therefore the scale a firm can reach. Corruption operates as a tax that is both unpredictable and unrecorded, and unpredictability deters investment more than a high but known rate would. And a state that cannot raise tax revenue cannot fund the health, education and infrastructure that every other strategy depends on.

This is why "institutional reform" appears in 4.10 as a strategy rather than as background. It is the precondition, and saying so is a strong closing judgement.
