Prior work
This trial does not extend or rely on any prior RCTs.
Many Filipina domestic workers finance their investments through loans from Hong Kong moneylenders, taking on the responsibility of expensive repayment installments and the risk of severe penalties in case of default.

This study tries to uncover the factors that drive this behaviours, focusing on migrants' lack of control over expenses. In particular it examines the role of family relationships and the financial discipline that loans provide.

We will use experimental methods with Filipina domestic workers in Hong Kong to generate data that will allow us to examine the mechanisms underlying their financial choices.

self-reported propensity to borrow for investment purposes, inform family member about loan, and projected propensity of family member to request a money transfer; actual choice to inform family member about study compensation
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Other outcomes that emerge from the study will be treated as secondary outcomes.
Secondary Outcomes (explanation)
The analysis of these other outcomes will be exploratory.

Experimental Design

Experimental Design
We follows a 2-intervention arm design. Participants are randomly assigned to either the "cooperative family" or the "uncooperative family" condition.
Experimental Design Details
Not available
Randomization Method
Randomisation will be done in the office via a computer before the fieldwork begins. A list with the order of assignment to conditions will be taken to the field, and participants will be assigned to the condition according to the list, in the order in which they arrive and are registered to participate. (Successful registration is subject to capacity constraints on the enumerator side.)
Randomization Unit
Was the treatment clustered?
