Background
• Debate regarding the capacity of developing countries, particularly low-income countries, to effectively spend significant new resources for health
![Page 4: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/4.jpg)
Measuring absorptive capacity
• Ratio of cumulative disbursements in each quarter over total grant commitment for Phase One.

Data and Methods
• Time series and cross sectional data on disbursement, grants characteristics and country characteristics
• Various estimation methods
![Page 6: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/6.jpg)
Major Findings
• Low-income countries, were more likely to have a higher rate of disbursement than high income countries holding everything else constant.
• For a given level of income, countries with less-developed health systems were more likely to have a higher rate of grant disbursement than nations with more-developed health systems.

Data and Methods
• Time series and cross sectional data from 1995 to 2004 on DTP3 coverage, country’s characteristics
• Various estimation methods
![Page 9: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/9.jpg)
Results• In countries with DTP3 coverage of 65%
or less at baseline, ISS spending per surviving child had a significant positive effect on DTP3 coverage.
• This effect was not present in countries with DTP3 coverage of 65–80% or 80% or more at baseline.

Output Measures
• Coverage/Effective Coverage- target diseases (HIV, Malaria, TB)- medical interventions for non-target diseases- basic medical services (i.e. immunization)
![Page 24: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/24.jpg)

Impact on government health spending – substitution effect?
• Government spending on health indicates the commitment of a government to public health.
• Expanding government spending on health is critical to maintaining financing sustainability in developing countries.
![Page 27: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/27.jpg)
Impact on interventions of non-target diseases or programs
• Immunization• Skilled-attendance at delivery
![Page 28: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/28.jpg)
Impact on population health outcomes
• Child mortality

Time-series and Cross-sectional Data
• Disbursements of GFATM, GAVI, and PEPFAR
• Government Health Spending- NHA data by WHO- OECD CRS on external sources
• Child mortality- IHME
• Country characteristics variables
![Page 30: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/30.jpg)

Dealing with missing data and low-quality data
• Developing estimation methods• Providing uncertainty level for estimates• Test the sensitivity of findings to estimates
derived from various methods
![Page 32: Measuring the Impact: Cross-Country Quantitative Analysis](https://reader036.fdocuments.in/reader036/viewer/2022081603/56815c7e550346895dca92d5/html5/thumbnails/32.jpg)

Challenges
• Outcome variables- How to differentiate the health outcomes by GHIs from that by health system
• Measurements of the strength of a health system
