Evaluation Fundamentals

The ultimate goal of all impact evaluations, and their greatest challenge, is to establish credibly that the intervention caused a difference in the lives of the participants. Using microinsurance as a context, this paper looks at the challenges, components and importance of impact evaluations.

Behavioral Foundations of Microcredit: Experimental and Survey Evidence From Rural India

In this report we use experimental measures of time discounting and risk aversion for villagers in south India to highlight behavioral features of microcredit, a financial tool designed to reduce  poverty and fix credit market imperfections. The evidence suggests that microcredit contracts may do more than reduce moral hazard and adverse selection by imposing new forms of discipline. We find that, conditional on borrowing from any source, women with present biased preferences are more likely than others to borrow through microcredit institutions. Another contribution of microcredit may thus be to provide helpful structure for borrowers with self-discipline problems.

Can Insurers Improve Healthcare Quality? Evidence from a Community Microinsurance Scheme in India

The authors of this study investigate whether having access to microinsurance improved the quality of healthcare for poor patients. They found that having access to insurance was not significantly associated with receiving better quality healthcare. The paper provides recommendations for healthcare providers to improve the quality of medical care received by their clients and suggestions for further research on the mechanisms that determine health care quality.

Take-up: Why Microfinance Take-up Rates Are Low & Why It Matters

Actively studying take-up rates, or participation rates, can help us understand the demand for different microfinance products, and how existing products might be improved to attract more clients and serve them better. This note reviews the evidence on take-up. It first discusses why take-up rates and participation are important, and how they can be measured. It then goes on to review survey data on why people don’t use microfinance products when they are available, and offers guidance on how low take-up rates might be addressed.

An Introduction to Impact Evaluations with Randomized Designs

Randomized experiments are an increasingly popular way to evaluate the impacts of development interventions. They provide hope that we can overcome important biases common to nearly all statistical evaluations. When done well, randomized control trials (RCTs) can provide clear, transparent, and credible evidence in complicated contexts, but their design and implementation is subject to a number of challenges. This note reviews some of the technical issues surrounding RCTs, describes four examples from microfinance, and discusses their advantages and drawbacks relative to other evaluation approaches.

Explaining Insurance: Implementing Consumer Education in CARE-India’s Insure Lives & Livelihood Program

When CARE India field officers delivered emergency relief services to the coastal regions ravaged by the 2004 tsunami, they were struck by the communities’ vulnerability to shocks and lack of access to appropriate risk protection tools, and assessed that microinsurance could be an effective product for these communities. Out of this determination, the CARE Insure Lives and Livelihoods (ILAL) microinsurance program was born. In collaboration with Allianz SE and Bajaj Allianz, CARE India designed a broad, long-term formal microinsurance program. The ILAL approach prioritized clients’ understanding of the value of insurance over purchasing a policy: the ultimate objective of the program was not to distribute policies, but to improve communities’ risk management capacities by improving their understanding of insurance.

Crop Price Indemnified Loans for Farmers: A Pilot Experiment in Rural Ghana

Farmers face a particular set of risks that complicate the decision to borrow. Researchers use a randomized experiment to investigate: 1) the role of crop-price risk in reducing demand for credit among farmers, and 2) how risk mitigation changes farmers' investment decisions. In rural Ghana they offer farmers loans with an indemnity component that forgives 50% of the loan if crop prices drop to a threshold price. A control group is offered a standard loan product. The authors find high loan uptake among all farmers and little significant impact of the indemnity component on uptake or other outcomes of interest.

Expanding Credit Access: Using Randomized Supply Decisions to Estimate the Impacts

Expanding access to commercial credit is a key ingredient of development strategies worldwide. There is less consensus on the role of consumer credit, particularly when extended at high interest rates. Popular skepticism about “unproductive” and “usurious” lending is fueled by academic work highlighting behavioral biases that induce overborrowing. We estimate the impacts of expanding access to consumer credit at 200% APR using a field experiment and follow-up survey and administrative data. The randomly assigned marginal loans produced significant net benefits for borrowers across a wide range of outcomes. There is also some evidence that the marginal loans were profitable.
