The Buzz of Cities

Dan Hoornweg's picture

BeeFor bees, bigger hives are better. 

Last week researchers at the University of Arizona published their findings: bees of bigger hives have more information and forage better. With improved communications, bees from the bigger hives sent new foragers to known resources up to four hours earlier than bees from smaller hives.1

This better communications also seems to work in bigger cities. Geoffrey West and the Santé Fe Institute provide impressive modeling on the scaling of cities. Double the size of a city and you get 1.15 times the growth of economy, patents and innovation. And as long as you can keep congestion and pollution in check, you can get this economic growth at only 0.85 times the cost of additional infrastructure. In other words, larger cities have a disproportionate impact on a country’s communications, and therefore a bigger impact on economy and culture.

“For the first time, I saw that the Government was thinking about the same issues as I was. I didn’t know.”

These hotel owner’s words are characteristic of many in Saint Vincent and the Grenadines. In many OECS countries, trust between the public and private sector may be at historically low levels but the implications for policy making are enormous, particularly at a time in which tough choices need to be made.

Inclusion is No Illusion

The World Bank’s recent report Bangladesh: Towards Accelerated, Inclusive and Sustainable Growth—Opportunities and Challenges examines inclusiveness along three dimensions—poverty, inequality, and the distribution of economic opportunities. The findings are summarized in this post.

Economic growth in the last two decades in Bangladesh has been pro-poor. Poverty declined significantly from 58.8 percent in 1991/92 to 31.5 percent in 2010. Bangladesh succeeded in “bending the arc of poverty reduction” in the decade ending 2010, a period in which the number of poor declined by around 15 million, compared with a decline of about 2.3 million in the preceding decade. There has also been regional convergence in poverty patterns during 2005-10. Poverty reduction in the lagging Western divisions (Rajshahi, Khulna, and Barisal) was larger than in the Eastern divisions. A number of other indicators of welfare also show notable improvements between 2000 and 2010 for the general population and the poor alike.

Income distribution stabilized after deteriorating in the 1990s. While comparisons based on consumption data have been used to argue that inequality in Bangladesh is low by international standards, when income rather than HIES consumption data are used, inequality appears to be much higher. The degree of income inequality was reasonably low and stable compared to countries such as Malaysia, Thailand and Philippines during the 1970s and 1980s. But there was a sharp increase between 1991-92 and 1995-96. Gini consumption concentration ratios based on HIES 2000, 2005, and 2010 data were almost unchanged while Gini income concentration ratios increased by 3.5 percent during 2000-05 followed by 1.9 percent decrease during 2005-10. The good news is it has been a race to the top in the past decade with consumption growing for the poor and non-poor alike. However, income inequality in Bangladesh is relatively high. Among Bangladesh’s peer group of countries only Sri Lanka has a higher income Gini and Cambodia is close.

Brazilian Competitiveness: Folia and Hangover

As the Carnival in Brazil kicked off last weekend, Brazilians were ready for a party. They have reasons to celebrate. Despite a lackluster GDP performance in the last two years, unemployment rates remain at record low levels.

How Remittances Grease the Wheels of Bangladesh’s Economy

What impact do remittances have on stimulating overall economic growth? Remittances can be used for consumption and investment which further stimulates demand for goods and services, as well as contribute to financial development. On the other hand, they can create dependence in recipients and cause real exchange-rate appreciation which adversely affects domestic production.

The answer is an empirical one which we can answer using available data. Our findings echo recent economic research which shows that remittances, even when not invested directly, can have an important multiplier effect.

In our study, we focused only on the magnitude of the impact of remittances on aggregate demand in Bangladesh and calculated the traditional Keynesian multiplier effect, that is how much income is generated from every remittance dollar, following the approach adopted by Nicholas Glytsos by estimating a consumption function, an investment function, and an imports function. To estimate the parameters we used data from the Bangladesh Bureau of Statistics national accounts covering the period 1981-2010. We ran simple Ordinary Least Squares regressions to estimate the structural parameters. Here is a summary of our results:

For Bangladesh, More Migrants Mean More Money

Zahid Hussain's picture

Remittances sent by migrant workers have emerged as a key driver of poverty reduction in many developing countries. Bangladesh has caught up with growing migration trends since the mid-70s when only 6,000 Bangladeshis were working abroad. Today, there are about 8 million. Migration has now become a major source of gainful employment for Bangladesh’s growing number of unemployed and under-employed labor force. The sharpest increase in the level of manpower exports occurred during 2006--2009. Remittances have grown at a rapid pace, particularly since 2004.

So, what are the key correlates of aggregate remittance inflows in Bangladesh? What does the data tell us about Bangladesh? Many researchers have used aggregate data to analyze the macro-economic factors affecting the behavior of remitters. For example, Barua et al (2007) show that income differentials between host and home country and devaluation of home country currency positively and high inflation rate in home country negatively affect workers’ remittances1. Hasan (2008) finds remittances respond positively to home interest rate and incomes in host countries2. Ordinary Least Squares estimation is frequently used to characterize the statistical relationships between aggregate remittance inflows and their proximate macro correlates.

The key finding is that a limited number of macroeconomic factors are important in predicting the behavior of aggregate remittances.

Development Optimism from Justin Lin: Review of 'The Quest for Prosperity'

Duncan Green's picture

‘Every developing country has the opportunity to grow at over 8% a year for 20-40 years, and to get rid of poverty within a generation.’ There’s something very refreshing about listening to East Asian development economists, in this case the prolific Justin Lin, a former World Bank chief economist, launching his new book The Quest for Prosperity, at ODI just before Christmas. The contrast between his can-do optimism and the dark clouds of Eurogloom and Afropessimism could not have been greater. But is he right?

While others in development wonkland are increasingly scathing about blueprints and best practice guidelines, Justin is unabashedly a man with a plan. The book takes his paper on ‘Growth identification and facilitation’, (see my earlier review, and Justin’s reply), and boils his thinking down into what he calls a ‘six point recipe’ for developing country governments.

Integrated Water Management in Cities: Can we get it right this time?

While on its path to becoming the largest city in the Americas, Sao Paulo used its natural capital - water - to generate electricity, fuel industry, and satiate its ever-growing population. Natural infrastructure was traded for the concrete form and the city’s great rivers paid a high price for industrialization.

The result? Tremendous growth (averaging 5% per annum) that stimulated rapid and unplanned migration to the city and environmental pollution.  Urban sprawl generated little to no infrastructure for managing water, sanitation and wastewater, or solid waste.  Clearing the land for houses caused erosion and compacted soils, and the resulting increase in runoff has made an already wet city even more prone to floods.  

Bangladesh: The Next China?

This is the sixth and last in a series of posts about the recent report, Bangladesh: Towards Accelerated, Inclusive and Sustainable Growth. The previous post looked at what sort of policies it will take to achieve the goal of middle income status by 2021.

Bangladesh, one of Asia’s youngest countries, is poised to exploit the long-awaited “demographic dividend” with a higher share of working-age population. Labor is Bangladesh’s strongest source of comparative advantage, and Bangladesh’s abundant and growing labor force is currently underutilized. Absorbing the growing labor force and utilizing better the existing stock of underemployed people requires expansion of labor-intensive activities. And that means expanding exports, as domestic consumption offers limited opportunities for specializing in labor-intensive production.

What are the potentials for expanding exports? Bangladesh’s competitors are becoming expensive places in which to do business. In the next three to four years, China’s exports of labor-intensive manufactured goods are projected to decline. It will no longer have one-third of the world market in garments, textiles, shoes, furniture, toys, electrical goods, car parts, plastic, and kitchen wares. Capturing just 1% of China’s manufacturing export markets would almost double Bangladesh’s manufactured exports.

What will it take for Bangladesh to become a Middle Income Country?

Zahid Hussain's picture

This is the fifth in a series of six posts about the recent report, Bangladesh: Towards Accelerated, Inclusive and Sustainable Growth. The previous post looked at the numbers behind Bangladesh’s goal of middle income status by 2021. The next and last post will look at the way forward.

For Bangladesh, achieving its goal of middle income status by 2021 will require more than business-as-usual: the average annual GDP growth rate will have to rise from the current 6 percent to 7.5-8 percent, while sustaining remittance growth at 8 plus percent. Faster growth in turn will depend on four main factors: (i) increased investment, (ii) faster human capital accumulation, (iii) enhanced productivity growth, and (iv) increased outward orientation.

Increase investment by at least 5 percentage points of GDP. Investment is constrained by infrastructure, business environment, land, and skills. Analysis based on Investment Climate Assessment surveys highlights the role of infrastructure in triggering a virtuous cycle of growth: better infrastructure will improve productivity which in turn will make exports more competitive and attract FDI, thus leading to further increase in productivity. Expanded provision of infrastructure has to come with easing difficulties in doing business, increasing access to serviced land, and meeting skill shortages.

Build on achievements in human capital formation. Bangladesh has done well in increasing the stock of human capital, topping the list of Asian countries along with Vietnam by improving average years of schooling by 1.3 during 2000-10. Our analysis indicates that achieving the needed GDP growth rate will require further increases from the current 5.8 to 7.3 average years of schooling. In addition, relatively low returns to schooling point to the importance of improving quality of education. These will require addressing external and internal inefficiency as well as weaknesses in education management and finance.
