Can modern technologies facilitate spatial and temporal price analysis?

Marko Rissanen's picture

The International Comparison Program (ICP) team in the World Bank Development Data Group commissioned a pilot data collection study utilizing modern information and communication technologies in 15 countries―Argentina, Bangladesh, Brazil, Cambodia, Colombia, Ghana, Indonesia, Kenya, Malawi, Nigeria, Peru, Philippines, South Africa, Venezuela and Vietnam―from December 2015 to August 2016.

The main aim of the pilot was to study the feasibility of a crowdsourced price data collection approach for a variety of spatial and temporal price studies and other applications. The anticipated benefits of the approach were the openness, accessibility, level of granularity, and timeliness of the collected data and related metadata; traits rarely true for datasets typically available to policymakers and researchers.

The data was collected through a privately-operated network of paid on-the-ground contributors that had access to a smartphone and a data collection application designed for the pilot. Price collection tasks and related guidance were pushed through the application to specific geographical locations. The contributors carried out the requested collection tasks and submitted price data and related metadata using the application. The contributors were subsequently compensated based on the task location and degree of difficulty.

The collected price data covers 162 tightly specified items for a variety of household goods and services, including food and non-alcoholic beverages; alcoholic beverages and tobacco; clothing and footwear; housing, water, electricity, gas and other fuels; furnishings, household equipment and routine household maintenance; health; transport; communication; recreation and culture; education; restaurants and hotels; and miscellaneous goods and services. The use of common item specifications aimed at ensuring the quality, as well as intra- and inter-country comparability, of the collected data.

In total, as many as 1,262,458 price observations―ranging from 196,188 observations for Brazil to 14,102 observations for Cambodia―were collected during the pilot. The figure below shows the cumulative number of collected price observations and outlets covered per each pilot country and month (mouse over the dashboard for additional details).

Interest rate caps: The theory and the practice

Aurora Ferrari's picture

Ceilings on lending rates remain a widely-used instrument in many EMDEs as well as developed economies. The economic and political rationale for putting ceilings on lending rates is to protect consumers from usury or to make credit cheaper and more accessible. Our recent working paper shows that at least 76 countries around the world, representing more than 80% of global GDP and global financial assets, impose some restrictions on lending rates. These countries are not clustered in specific regions or income groups, but spread across all geographic and income dimensions.

Five lessons in infrastructure pricing from East Asia and Pacific

In the infrastructure domain, “price” is a prism with many façades.
 
An infrastructure economist sees price in graphic terms: the coordinates of a point where demand and supply curves intersect.
 
For governments, price relates to budget lines, as part of public spending to develop infrastructure networks.
 
Utility managers view price as a decision: the amount to charge for each unit of service in order to recover the costs of production and (possibly) earn a profit.
 
But for most people, price comes with simple question: how much is the tariff I have to pay for the service, and can I afford it?

To unlock student potential in East Asia Pacific, be demanding and supportive of teachers

Michael Crawford's picture

Among the 29 countries and economies of the East Asia and Pacific region, one finds some of the world’s most successful education systems. Seven out of the top 10 highest average scorers on internationally comparable tests such as PISA and TIMSS are from the region, with Japan, Republic of Korea, Singapore, and Hong Kong (China) consistently among the best. 

But, more significantly, one also finds that great performance is not limited to school systems in the region’s high-income countries. School systems in middle-income Vietnam and China (specifically the provinces of Beijing, Shanghai, Jiangsu, and Guangdong) score better than the average OECD country, despite having much lower GDP per capita. What is more, scores from both China and Vietnam show that poor students are not being left behind. Students from the second-lowest income quintile score better than the average OECD student, and even the very poorest test takers outscore students from some wealthy countries. As the graph below shows, however, other countries in the region have yet to achieve similar results.

Can Asia-Pacific achieve sustainable energy for all?

Sharmila Bellur's picture

The Asia-Pacific region, comprised of 58 economies, is geographically expansive and a picture of diversity. The trends for sustainable energy in Asia-Pacific, which mirror the region’s economic and resource diversity, are underscored by the fact that Asia-Pacific comprises 60 percent of the global population, generates 32 percent of global GDP, consumes more than half of the global energy supply, while generating 55 percent of global emissions from fuel combustion. The region’s sustainable energy picture is captured in a new report by the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP), entitled “Asia-Pacific Progress in Sustainable Energy: A Global Tracking Framework 2017 Regional Assessment Report.” The report is based on the World Bank and International Energy Agency’s Global Tracking Framework (GTF), which tracks the progress of countries on energy access, energy efficiency, and renewable energy under Sustainable Development Goal 7 (SDG7).

Four overarching sustainable energy themes emerge from the report:

Creating “Solid Ground” for gender equality in land access

Despite the fact that women represent about half of the global population, produce the majority of global food supply, and perform 60% to 80% of the agricultural work in developing countries, women own less than 20% of land worldwide.

Written laws often fall short of adequately protecting women’s tenure rights; while in some countries, formal national laws explicitly discriminate against women. In post-disaster rehabilitation and reconstruction, women face particular hurdles to secure tenure and shelter. Even in areas with strong protections of equality and non-discrimination, displaced women often struggle to assert their property rights.

On March 8, 2016, on the occasion of International Women’s Day, Habitat for Humanity International launched its first global advocacy campaign, “Solid Ground,” which envisions a world where everyone has access to land for shelter. Promoting gender equality and addressing inequitable or unenforced laws, policies, and customary practices affecting women’s rights to security of tenure and inheritance, has been a primary focus of the campaign.

Now mid-way through the campaign, Solid Ground has grown to include 37 national Habitat for Humanity organizations, 17 partner organizations, an active microsite solidgroundcampaign.org (and in Spanish, SueloUrbano.org), and has provided direct financial assistance to country programs working on gender and land issues. In its first year, over 1.3 million people are projected to have improved access to land for shelter through the Solid Ground campaign with a goal of reaching 10 million people, especially women.

Through a variety of efforts to build capacity, mobilize allies, influence policymakers, and work together with our partners, we are seeing signs of progress being made to achieve successful outcomes in helping facilitate women’s land ownership and empowering women to understand and achieve their rights. A sampling of some strategies, cases, and upcoming plans are highlighted below. 

Let’s talk money: New campaign helps Cambodia’s new generation on financial management

The World Bank partnered with the Women’s Media Center “Let’s Talk Money” radio show to help build financial stability in Cambodia.
Risky financial behaviors among Cambodians of the post-millennial generation have become more widespread in the country, especially among the 18-35 age group. While they are important customers for the financial and banking sectors, their behaviors are often dominated by lavish spending and excessive borrowing. 
 

The forgotten dimension of the SDG indicators – Social Capital

Jos Verbeek's picture

The 2030 Agenda for Sustainable Development rightfully points out that sustainability has three dimensions: economic, environmental, and social. The first two are well understood and well measured.
 
Economic sustainability has a whole strand of literature and the World Bank and IMF devote a lot of attention to debt and fiscal sustainability in their reports. Just open any Article 4 consultation or any public expenditure review and you will find some form of fiscal or debt sustainability analysis.
 
The same can be said about environmental sustainability. Since Cancun (COP16), countries prepare National Adaptation Plans, and since COP 21, they have prepared Nationally Determined Contributions (NDCs) which focus on domestic mitigation measures to address climate change. 

Four political errors to avoid in achieving water and sanitation for all

Nathaniel Mason's picture

Eliminating inequality is integral to the Sustainable Development Goals , from ‘universal access’ to water, to ending poverty ‘everywhere’. Yet in a world where the politics of who gets what is increasingly polarised, leaving no-one behind is fundamentally a political project.

In a recent study with WaterAid in Nepal, for example, we found that in rural areas a combination of poverty, caste, and geography have shut the poorest fifth out of politics. While access to water has increased significantly for others, they are lagging behind.

Every city, country or district has its own political rules, most of which aren’t written down. Yet despite all this complexity, experts working on essential services like water, sanitation, health or education can avoid some common political missteps, wherever they work. Here are four most typical ones:

Join now! Everything you ever wanted to know about student assessments

Marguerite Clarke's picture


Assessments make a lot of people nervous, and I’m not just talking about the students who have to take them. As a psychometrician (assessment expert) and World Bank staffer, I’ve worked on assessment projects in more than 30 countries around the world over the past 10 years. Time and again, I’ve found great interest in student assessment as a tool for monitoring and supporting student learning coupled with great unease over how exactly to go about ‘doing’ an assessment.
