Macroeconomics and Economic Growth

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:

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.

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.

This is the fourth in a series of six posts about the recent report, Bangladesh: Towards Accelerated, Inclusive and Sustainable Growth. The last post, Be Happy Yet Do Worry: Explaining Resilience in Bangladesh's Economy, explained how the economy has withstood recent shocks. The next post will look at what sort of policies it will take to achieve the goal of middle income status by 2021.

Bangladesh’s economic growth has followed a path both theory and international experience would expect. Starting from a low income level, growth initially tends to accelerate through capital accumulation in a market economy. This is what happened in Bangladesh during the four decades since independence in 1971. A recent article in The Economist rightly said, “Bangladesh has become a model of what can be done”. Progress achieved so far provides a credible basis for aspiring to be a middle income nation by 2021, as observed in the World Bank’s recent report “Bangladesh: Towards Accelerated, Inclusive and Sustainable Growth—Opportunities and Challenges”.

Would it take more than just maintaining recent growth rates to achieve middle-income country (MIC) status? It is important to be clear about how middle-income status is defined. It is based on nominal Gross National Income (GNI) measured in Atlas dollars, not real Gross Domestic Product (GDP). Economies are divided according to 2012 GNI per capita, calculated using the World Bank Atlas method. The income thresholds are: low income—$1,025 or less; lower middle income—$1,026 to $4035; upper middle income—$4036 to $12,475; and high income—$12,476 or more.

At current prices, Bangladesh’s per capita GNI would have to exceed US$1,025 to reach the lower end of “low middle income” status. Nominal Atlas GNI per capita, currently $851, will need to grow at a sustained 2.1% and nominal Atlas total GDP will need to grow at 3.5% per annum from now onwards for Bangladesh to reach the middle-income threshold by 2021, when Bangladesh will celebrate its 50th year of independence.
