Top 7 disruptive technologies for cities

Abhas Jha's picture

Economic growth does not evenly spread within countries: some regions benefit, while other regions lag behind. This is as true in the European Union (EU) as in most other parts of the world, despite  significant convergence efforts in the EU. The leading regions in Europe have, on average, 2.3 times the GDP per capita of their poorest counterparts.

There are 5 things you (probably) didn’t know about the phenomenon of “lagging regions” within the EU.
 

Can blockchain disrupt gender inequality?

Alicia Hammond's picture

Blockchain is the subject of considerable hype, thanks largely to the rise (and fall and rise...) of high profile digital currencies. Beyond this spotlight, development experts and innovators are exploring whether the technology behind cryptocurrencies can be leveraged to advance gender equality.
 
Blockchain is a distributed ledger technology  that facilitates peer-to-peer transactions without using an intermediary. (The technology is also notoriously difficult to follow, but we find this brief video helpful and this talk explains blockchain well, if you have a bit more time.) Put simply, the system is maintained by collaboration, code and sometimes competition. Many experts refer to Google Docs to explain the concept: multiple users can access the same document simultaneously and they can all see the changes. This feature potentially makes it suited for validating records and processing financial transactions in the absence of strong institutions.

World Bank’s ‘Global Dataset’ Offers New Way for Comparing Countries’ Educational Performance
Market Brief Ed Week
For years, efforts to explore and compare the educational performance of impoverished countries–and by implication, their economic potential–have been stymied by a lack of useful data. An ambitious new analysis by the World Bank aims to change that. A “global dataset” unveiled by the international development organization uses statistical methods to put the results of much-publicized international tests like the PISA and TIMSS–which many poor nations do not take part in–on a comparable scale as regional exams commonly used by developing countries. The result is a new method for comparing the test performance of rich and poor nations that World Bank researchers say hasn’t been accomplished before.
 

Can cryptocurrencies and blockchain help fight corruption?

Blockchain and cryptocurrencies similar to Bitcoin could transform the way we make payments and do business. They also hold great promise as a method of fighting corruption.

Technological advances have made it possible to dramatically increase the accountability and transparency of public financing to reduce corruption. For example, if a government decides to construct a road, it can now track how each dollar is being spent, identify all the users of the funds, and ensure that only those authorized to spend money do so on originally intended expenses within the permitted time. Fraud and corruption investigations that now take on average 15 months could be performed at the touch of a button and at a fraction of the cost. More importantly, this type of financial tracking would be a deterrent for bribes in the public sector, which amount to between $1.5 trillion and $2 trillion annually, roughly 2 percent of global GDP. This in turn would increase development impact. All it would take is adopting a cryptocurrency and using blockchain software.

Why technology will disrupt and transform Africa’s agriculture sector—in a good way

Agriculture is critical to some of Africa’s biggest development goals. The sector is an engine of job creation: Farming alone currently accounts for about 60 percent of total employment in sub-Saharan Africa, while the share of jobs across the food system is potentially much larger. In Ethiopia, Malawi, Mozambique, Tanzania, Uganda, and Zambia, the food system is projected to add more jobs than the rest of the economy between 2010 and 2025. Agriculture is also a driver of inclusive and sustainable growth, and the foundation of a food system that provides nutritious, safe, and affordable food. 

Blockchain for Development: A Handy Bluffers’ Guide

Duncan Green's picture

Top tip: if you’re in a meeting discussing anything to do with finance, at some point look wise and say ‘you do realize, blockchain is likely to change everything.’ Of course, there is always a terrifying chance that someone will ask what you actually mean. Worry not, because IDS has produced a handy bluffer’s guide to help you respond. Blockchain for Development – Hope or Hype?, by Kevin Hernandez, is the latest in IDS’ ‘Rapid Response Briefings’ series, (which itself is a nice example of how research institutions can work better around critical junctures/windows of opportunity). It’s only four pages, but in case even that is too onerous, here are some excerpts (aka a bluffer’s guide to the bluffer’s guide).

‘What is blockchain technology?

At its heart, the blockchain is a ledger. It is a digital ledger of transactions that is distributed, verified and monitored by multiple sources simultaneously. It may be difficult to think of something as basic as the way we keep and maintain records as a technology, but this is because record-keeping is so ingrained in daily life, albeit often invisibly. The ubiquity of ledgers is in part the reason why blockchains are held as having so much disruptive potential. Traditionally, ledgers have enabled and facilitated vital functions, with the help of trusted third parties such as financial institutions and governments. These include: ensuring us of who owns what; validating transactions; or verifying that a given piece of information is true.

Compulsory voting results in more evenly distributed political knowledge
LSE Blog

Given interminably low rates of voter turnout across most Western democracies, looking to compulsory voting as a panacea for democracy’s ills seems sensible. Comparatively low – or declining – voter turnout is viewed generally as a symptom of civic disengagement from politics. Compulsory voting can also mitigate inequality in participation and representation. Citizens with the most resources and influence are typically the most likely to vote, and by voting for candidates and parties who reflect their interests, their participation can perpetuate systemic social biases.

Blockchain technology: Redefining trust for a global, digital economy

MIT Media Lab’s Digital Currency Initiative platform

With Google Trends data showing that searches for the word “blockchain” have exponentially increased, we may be entering the peak of the hype cycle for blockchain and distributed ledger technology.

But here’s the thing: the blockchain is a major breakthrough. That’s because its decentralized approach to verifying changes in important information addresses the centuries-old problem of trust, a social resource that is all too often in short supply, especially amid the current era’s rampant concerns over the security of valuable data. It turns out that fixing that can be a boon for financial inclusion and other basic services delivery, helping to achieve the global objectives laid out in the Sustainable Development Goals (SDGs).

Sorting out hype from reality may depend on how well we identify where institutions that have until now played a role in mediating trust between people are falling short, especially in the key area of money. Deploying the blockchain in those settings to generate secure, decentralized trust could achieve great strides in inclusion and innovation.

What do we mean by decentralized trust? The concept is unfamiliar in part because its converse -- centralized trust – is something that we often take for granted, at least while it’s working. But if we look at the history of transactions since the early barter systems to modern-day digital money exchanges, we can see how different trust protocols for keeping track of our exchanges of value have evolved and how, in each case, centralizing trust within particular institutions has periodically caused problems.

As strategies for dealing with this challenge evolved and as the complexity and frequency of transactions grew, different trust bearers emerged. We went from relying on the memory and discretion of tribal leaders, to central governments issuing currencies in the form of precious metals, to commercial banks acting as trusted intermediaries and issuing their own bank notes, to central banks managing a hybrid system in which sovereign fiat banknotes circulate alongside a debt/credit form of money managed by regulated banks and internal ledgers.
