Differential Binding Constraints Across Financial Product Markets

In Simple Words

Think of a buffet where diners leave the bread and rice untouched because their cupboards at home are already full, but eagerly grab a rare dessert they cannot get anywhere else. Low demand for standard credit or savings indicates those pantries were already served, whereas high demand for insurance shows a genuine empty shelf in their household safety net.

Research question

Development programs frequently assume that low-income migrant families face blanket access barriers across all formal financial services. Identifying which specific financial product markets actually suffer from binding access constraints is essential for targeted policy interventions.

Participants

N = 1,800 transnational households in Cabanatuan City and surrounding localities, Philippines.

Study Design

Randomized controlled trial offering formal microloans (ASKI), bank savings accounts (BPI BPinoy), and micro-insurance (ASKI life/accident insurance).

Results

Take-up for offered savings accounts was only ~1 percentage point (9 total individuals) and microloans near zero (2 individuals), whereas micro-insurance take-up surged by 25.1 to 28.0 percentage points (p < 0.01).

Takeaway

Prioritize financial access interventions specifically on underserved risk-coping products like micro-insurance rather than expanding existing formal credit and savings access in saturated markets.
