Widget 1: Scenarios for saving, investment, and current accounts through 2030
This widget allows you to select countries (or country aggregates) for the main variables---saving, investment, and the current account---for the projections under each of the two main scenarios of the report (gradual and rapid convergence). For saving and investment, you can select these as either a share of GDP, or in 2010 U.S. dollars (although not both in the same chart), while for the current account, you can select this as the current account as a percent of GDP. Hovering over any given observation will provide information on the observation.

Widget 2: Scenarios for infrastructure investment needs by country and sector through 2030
This widget allows you to vary the baseline assumptions used in the computation for infrastructure investment. You can select either one sector (cellular telecom, fixed telecom, power, roads, sanitation, and water) and many countries, or multiple sectors for a given country (you can click on the "show on chart" check box to indicate whether you wish that sector to be included in the chart; the default is that all are included). The assumptions used for growth, etc. are those used to generate the main results in chapter 1 of the Global Development Horizons: Capital for the Future report (additional details are documented in online annex 1.4 of the report). You can modify these as you wish, and to implement the change, click on "Refresh Chart." However, there is no guarantee that the numbers that are calculated will be sensible if these assumptions are changed, so the results should be interpreted with caution.

Widget 3: Scenarios of public expenditures on pensions, health care, and education through 2050
This widget allows you to project public expenditures on three age-related items—pensions, health care, and education—for six developing countries. You can keep the ratio of average expenditures per person of each age to average income per working age person constant, in which changes in expenditures are driven purely by changes in the age distribution of the population. Or you can let this ratio (for people of each age) converge smoothly, by 2050, to that of the U.S. in 2003, or to that of Sweden in 2003, to illustrate hypothetical changes in the age-specific overage and average generosity of public pension, health care, and education systems. You can also graph intermediate cases between these two convergence cases.
