Poor show of productivity driving growth


| by R.M.B Senanayake

( October 21, 2012, Colombo, Sri Lanka Guardian) Our capacity to produce goods and services is determined by how much labour we have, how many hours workers work, the workers’ skills and intensity of work, the amount of capital workers have with which to work, and technology. Over time, due to changes in all of these, our real GDP has increased.

Labour force likely to stagnate

We have a large population with a large percentage of the labour force at work.  But increases in our labour force is now very low - a mere 0.1% in 2011 from 48.1% in 2010. The labour force in 2011 was 8.24 million. It comprised 7.89 million employed persons and 0.34 million unemployed persons. We seem to be reaching saturation as regards the availability of labour and any further increase is likely only from the female participation rate in the economy, through more women entering employment. We can of course increase the number of working hours  but it is regulated by law to 45-48 hours per week. During their early development the workers in Japan and Korea worked for 55 hours per week.  We also have far too many holidays and excessive leave entitlements. These reduced hours of work means lower growth.

Poor savings growth

The amount of accumulation of physical capital affects the productivity of the workers. In other Asian countries the fall in the growth of population has led to an increase in household savings which could be used to fund more investment. But this has not happened in Sri Lanka and the increase in domestic savings including the savings of  those employed abroad is still an abysmal 20% whereas China has 50% and India 35%. Our welfare state provide for the people, services which eliminate their need to save for sickness, education and old age. But owing to foreign direct investment and our openness to the world, the workers have significantly larger amounts of capital and have adopted new ways of producing and organising production. Increases in physical capital in the form of machinery, buildings, roads and bridges have been largely funded by foreign loans and since the country achieved middle income status, we have seen an increasing share of commercial borrowings and special bilateral loans from countries such as China. The private sector still contributes to the bulk of the investment but there is increasing doubts whether the government investment is producing returns or is wasteful. The right sort of public infrastructure spending could raise returns to the private sector. But both types of investment should be governed by market prices and market returns.

Productivity matters

Productivity growth is a crucial source of growth in living standards. Productivity growth can be defined as the adding of value  to production, meaning more income is available to be distributed. Productivity also determines the competitiveness of our goods in the world market. Since trade increases in growth and welfare we must promote free trade and to benefit from it, we need to be competitive.   Continuous increases in productivity contribute to sustainable growth. The quantity of labour matters less than work ethics and the quality of labour. We have put a lot of resources into primary, secondary and university education. But we have had poor returns to education. What matters most is primary and secondary education rather than university education. We have increased the numbers in university education and except for the medical and engineering education, the returns are dismal. A large number of graduates are unemployed. More investment in university education is in my view a waste of resources.

Primary and secondary education increases the productivity of the mass of workers, which is what counts in a country whose comparative advantage at best, lies in light manufacturing and low end services. Today there is a scarcity of workers and most of the workers are drawn from the estate sector. We have also sadly neglected the production of skilled workers like carpenters, plumbers, bricklayers, masons among others. Many of them have gone abroad and we have failed to train sufficient numbers to take their place. In fact putting more resources into university education only worsens the income inequality. The well-off are drawn from the university educated and so why pile on more funds for university education?  Let those who hanker after it pay for it themselves for they stand to benefit. It is an investment for them and like all investments they will not always succeed. 

Productivity and relative prices

Economists refer to productivity in the firm, the industry or the whole economy as a reference to minimising the use of inputs of labor capital and land to produce a given unit of output. The individual firm takes the prices of its inputs; labor, raw materials, land among others from the market. If the productivity of the firm is to contribute to productivity in the industry or the macro-economy, the relative pricing of these resources should be based on their relative scarcity in relation to the demand for them. Where labour is plentiful the wages should be low in relation to capital. We do not have an optimum pricing of factors of production. We have distortions arising from government wage legislation such as minimum wages; tax incentives by way of reduced duties for some capital goods like machinery and equipment. But this distorts the relative cost of capital in relation to labour. The over-protective labour laws make it impossible to terminate contracts of employees who are not adding to productivity. If a product can be made with less labour it should be legally possible for the manufacturer to reduce such excess labour.

So it is useless to talk of improving the productivity of labour in the work place since the employer cannot make the necessary arrangements to increase productivity. From the economy’s point of view what counts is the allocative efficiency of labour, land and capital. It is also necessary that the exchange rate and the interest rates are market determined to reflect the relative supply and demand situations. Productivity also determines the competitiveness of our goods in the world market. Since trade increases growth and welfare we must promote freer trade with a free exchange rate, and to benefit from it we need to be competitive.   Suppose you buy a new machine for your factory which is extremely efficient in producing a product out of raw materials when  raw materials have to be imported ; if there are high tariffs on such import or there are cumbersome government regulations on such imports then there may not be timely and adequate raw material for the machine’s capacity which would result in the operation being unproductive. Thus  the import of raw materials should be liberalised and the tariffs on them should be low. Our ranking in education on every international indicator is poor.

We have a stiff labour market which is not conducive to increases in productivity. Our stiff labour market prevents the adjustment of wages to match productivity. But the number of hours worked is regulated by law and the intensity of work depends on the individual worker although norms could be set to be achieved by all workers.  Enforcing standards is difficult since the ultimate sanction of termination of services is not possible. 

There are also obstacles to starting a business which discourage new entrepreneurs entering the economic scene. There are inadequate facilities for small and medium scale enterprises to raise money from a stratified and risk averse banking system. There is also the ceiling on credit of 18% imposed by the Central Bank which makes it difficult for SMEs to borrow money.

Measures of productivity

Every productivity measure, implicitly or explicitly, relates to a specific producer unit: an establishment, a firm, an industry, a sector or an entire economy. Productivity is a measure of the output produced by a unit of input. Productivity is usually measured as a percentage of a specific unit such as land or labour. Alternatively it can be expressed as maximising the output in relation to a given input of resources. Economists talk of the productivity of capital and labour or total factor productivity, which is really what matters for sustainable economic growth. 

A connected concept is efficiency. Management efficiency is not the same thing as productivity efficiency , which is usually measured as a function of all costs (labour, land, among others) as a percentage of sales. To do a 20-minute job in 10 minutes is productive and efficient. To do a 20-minute job in 20 minutes is just productive. Efficiency is also important since it affects productivity of the firm and the industry. It is based on materials spent in production. Lesser the time, and energy materials are used to produce the product, higher the efficiency. Efficiency is a measure of waste in a system.

The economic theory of productivity measurement is based on productivity measures in a production-function context and linked to the analysis of economic growth. The field has developed considerably since Tinbergen and now offers a consistent approach that integrates the theory of the firm, index number theory and national accounts. Robert Solow’s growth accounting approach identifies the contributions of different inputs to output growth.

Growth not sustainable without increase in productivity

There is much hype about the 8% growth rate for two years in 2010 and 2011. Growth was based on infrastructure investment. But there is no cost-benefit studies to show how productive the    capital or the labor employed in such projects is.
