economic growth across the world today: evidence
from country panel data

Abstract
Over the recent four decades, the set of modern manufacturing, technology, and organizational
innovations has been important in shaping a new industrial era. Based on the Lean Production
System (LPS), as a one of the most significant organizational cum technical innovations in
industrial development, modern manufacturing has started in Japan and subsequently evolved
in many industrialized economies, such as the USA, Korea and other countries. Its main
characteristics are concentrated on a concerted effort to reduce any type of waste in production,
and hence reductions in inventories and defects are some of its main consequences. There has
been a prolific literature on the benefits of LPS on a microeconomic basis for various firms and
industries in a multitude of countries, by using both primary (survey) and secondary data.
However, so far there has not been any specific evidence on a macroeconomic basis (hence by
using secondary data only). Consequently, this paper endeavors to capture and document the
effects of LPS on macro-economic growth based on a comprehensive panel country-level
empirical analysis. Using 30 years of relevant panel data from 1979 to 2008 and for 69
countries across the globe, we use panel econometric techniques such as fixed effects, GMM,
and Hausman-Taylor models to assess the LPS’s impact on economies. For this assessment we
use a carefully chosen and well-established proxy, the inventories to sales ratio, in order to
measure LPS. Thus, we found that LPS has played a significant role in the economic
development of most developed countries. The effects of LPS on economic growth are therefore
a significant feature of modern manufacturing, which cannot be neglected when considering
industrial policy in various countries, especially those such as Korea that are still in the process
of establishing themselves in the international competitive arena as new strong economic
powers. Our paper, overall, includes micro and macro issues in order to assess macro-economic
growth.

1. Introduction
It is well known that the mass production system that took place in the USA during the
second industrial revolution during the period of approximately 50 years from 1870 to 1920 has
been gradually replaced by modern manufacturing techniques which started with Toyota in
Japan since the 1960s. By the first decade of the 21st century, there is evidence that many
countries in the world, especially advanced ones, are using modern techniques of technology
and organization usually termed under the umbrella of ‘flexible production’, just-in-time (JIT)
and quality control, lean production, and so on. A prolific literature covers all these historical
developments in journals and books in various disciplines. Thus, in economics, Milgrom and
Roberts (1990, p. 511) have already stated that “…Manufacturing is undergoing a revolution.
The mass production model is being replaced by a vision of a flexible multiproduct firm that
emphasizes quality and speedy response to market conditions while utilizing technologically
advanced equipment and new forms of organization…” These authors have shown through
rigorous models of complementarities that we should expect to see a simultaneous change in
several variables such as lower prices, higher quality in production, lower inventories, fewer
defects, lower wastage, and so on (all this will be further explained below).
Thus, we want to emphasize from the outset that one of the most important
consequences of this modern manufacturing system (henceforth called lean production system
or LPS) is the continuous through time reduction in inventories. This reduction is independent
of the business cycle as we shall see later. We will hence use inventories (as a ratio to sales in
order to take into account the size factor) as a good proxy of the LPS. This proxy has been used
by many other researchers, especially on a micro basis (firm or sector level). We will justify the
use of this proxy further below.
The aim of our paper is to provide empirical evidence as to whether our sample of xx
countries have been modernizing their economies overall by adopting principles of the LPS. On
3
a macro-economic basis our study is the first one to attempt such an empirical study. On a micro
economic basis, there has already been substantial evidence about the adoption of LPS in firms
and sectors in countries such as Japan, Korea, and the USA. However, it is not obvious a priori
that if LPS is adopted in some firms and sectors, then that means that LPS is also adopted
overall (or on average) in the relevant countries. Especially, this is even less evident on the
macro basis as the proxy which researchers use on a micro basis (inventories to sales ratio) can
effectively be used on macro basis. The reason for this latter argument is that if inventories
diminish in some firms and sectors then they might increase in some others. We will examine all
this in section 2 where we present the theoretical background of our paper.
In section 3 we present our data details and empirical results. There we will use panel
data econometric techniques such as fixed effects, GMM, and the Hausman Taylor model with
our dependent variable being the growth rate in GDP and the independent variables being the
usual variables used in such models (such as initial GDP) and our proxy for LPS. In section 4
we conclude.
2. Theoretical background
There are two issues which will assist us in clarifying our proposed hypotheses to test.
The first one is related to technology which is so important in influencing economic growth and
the second one is related to the behavior of inventories. Regarding the former, we will adopt the
United Nations Centre on Transnational Corporations (UNCTC, 1985, p. 119) definition:
‘Technology may be embodied in the form of capital goods, such as machinery, equipment and
physical structures; or it may be disembodied in such forms as industrial property rights
unpatented know-how, management and organization (authors’ emphasis) and design and
operating instructions for production systems’.
Accordingly, technology has two different aspects: one that is embodied in the form of
physical products (technical innovations; hereafter referred to as “TIs”) and the other is
4
disembodied in such as know-how, managerial, operational and organizational technology
(organizational innovations; hereafter referred to as “OIs”). This view of distinguishing between
embodied and the disembodied technology (or TIs and OIs) is shared by many scholars; for
example Brown (1968), Peters (1980), Romer (1990), Tomer (1990), Nelson (1996), Sanidas
(2004, 2005, 2006), Marshall (1890), Schumpeter (1934, 1942), and others. The distinction
between TIs and OIs concerning technology will assist us in better understanding the
functioning and consequences of LPS.
Effectively, modern production is heavily based on OIs which we can also call
organizational process innovations (such as just-in-time, kanban, and kaizen), as against
technological process innovations (Edquist et al, 2001). A first succinct but holistic definition of
JIT is given in Harrison A. (1994, p.175). This author distinguishes three areas of excellence
regarding the JIT philosophy or, as it is also called, ‘Lean Production’, or ‘World Class
Manufacturing’:
Techniques are systematically put in place to attack all sources and causes of waste.
Everybody is included and participates in the JIT process and management.
Continuous improvement searches for the ideal case of zero scrap, defects, and
inventories.
Womack et al (1990, p. 13) sheds some light on the definition of the lean production system
(LPS):
“...Lean production (a term coined by IMVP researcher John Krafcik) is ‘lean’ because it uses
less of everything compared with mass production- half the human effort in the factory, half the
manufacturing space, half the investment in tools, half the engineering hours to develop a new
product in half the time. Also, it requires keeping far less than half the needed inventory on site,
results in many fewer defects, and produces a greater and ever growing variety of products...”
Imai (1997, p. 45) summarizes the benefits from implementation of JIT/QC as follows
(explanation of Japanese words in the quotation are provided below).

“…Opportunities for cost reduction on-site may be expressed in terms of muda. The
best way to reduce costs in gemba is to eliminate excess use of resources. To reduce
costs, the following seven activities should be carried out simultaneously, with quality
improvement being the most important. The other six major cost-reduction activities
may be regarded as part of the process quality in a broader sense:
1. Improve quality.
2. Improve productivity.
3. Reduce inventory.
4. Shorten the production line.
5. Reduce machine downtime.
6. Reduce space.
7. Reduce lead-time.
These efforts to eliminate muda will reduce the overall cost of operations…”
Note that muda means waste and gemba means shop floor or work place in general. Quality
refers to both process quality and gemba quality. The former includes the quality of work in
developing, making, and selling products or services. The latter refers to managing resources
and it includes the five M’s, namely man, machine, material, method, and measurement.
To further appreciate the OIs introduced in the LPS it would be useful to compare the mass
production system main characteristics with those of the LPS. First, Table 1 presents the general
comparison between JIT/QC system and non-JIT/QC system. Second, Table 2 presents a
comparison between three production systems, including LPS.

In general, OIs are linked with production systems and have an important role to play in
economic growth and development. However, OIs are not only linked with production systems.
Thus, Blomstrom, Lipsey and Zejan (1996) reexamined the rate of per-capita growth with post-
World War II data and found no evidence that fixed investment (or equipment investment). They
concluded that emphasis should be put on the importance of institutions, economic policies,
foreign direct investment and the efficient use of investments (which are all related to OIs) as
the cause of economic growth. Hall and Jones (1998), in their empirical study, took a step-by-
step approach to the analysis of the determinants of economic growth across countries and they
7
provided evidence of a causal effect of social infrastructure (institutional quality) on worker’s
productivity growth, given that social-infrastructure encourages the adoption and
implementation of TIs and OIs.
Sachs and Vial (2001) examine the competitiveness of Latin America Countries (LAC)
with five factors including technology (TIs for this case), institutional quality and openness, and
explain the LAC weak economic performance. They emphasize the necessity of wise use of
natural resources (which are rather of the institutional or of OIs for this case) for the countries to
grow their national competitiveness. Denison (1962) explicitly distinguishes between OIs and
TIs and discusses about OIs’ possible great impact on productivity; Mansfield (1968) lists OIs,
namely new techniques of organization, marketing, and management, as a source of growth;
Lucas (1993) concludes his paper by analyzing the economic miracles of East Asia, with an
emphasis on learning-by-doing growth through human capital accumulation, if OIs (roles of
workers and managers) properly operate; Romer (1993, 1994) suggests that ideas (potentially
OIs) can positively affect economic growth; Stiglitz (1996) explains the East Asian miraculous
growth with governmental OIs; Chandler (1997) discusses managerial aspects of OIs; Hall
(2000, p. 1) discusses OIs through some modeling and says that “when an economy is well-
organized, it is more productive”.
Pack (1994) views OIs as improvements in knowledge (such as organization routines,
rearrangement of the flow of material in a factory, better management of inventory, or other
changes that do not require knowledge to be embodied in new equipment) impacting on the
annual rate of productivity. Pack (1994) introduces issues of shortcomings and difficulties of
endogenous theory to construct his empirical work. He suggests some theoretical
accommodation to the endogenous theory according to the reality of economic growth through
new business practices, OIs. Thus, the annual rate of productivity improvement can be
interpreted in improvements in both TIs and OIs (Pack 1994). Other studies that have
incorporated OIs in the empirical models are those by Baily and Gersbach (1995), Lieberman
8
and Demeester (1999), Sanidas (2005) and Singh (2008) who include OIs in their empirical
growth models.
Over the last 30 years, OIs (such as those incorporated in the LPS and influenced by
institutions and other societal structures) have been prevailing in many developing and
developed countries, playing a significant role in economic growth. It seems that OIs have been
adapted and assimilated by developing countries and particularly the NIEs according to their
own circumstances by imitating the OIs in advanced countries such as the United States and
Japan (Hausmann and Rodrik 2003). Thus the implementation and localization of OIs may vary
across countries, yet their consequences and results will much be the same. As a consequence of
the implementation of OIs, economies reduce unnecessary investments, minimize inventories
and avoid bearing redundant costs in production. Productivity in firms (or countries) may yield
a great increase in responsiveness to both supply and demand through drastic reduction in
transaction and other types of opportunity costs.
Inclusion of OIs in the production function relative to the inclusion of TIs is rather rare.
For instance, Menard (1996, p. 291) remarked,‘…Thus, the production function should include
three related inputs: capital, labor, and organizational capabilities: Q = Q (K, L, O)…’ (p. 291).
In addition, Lydall (1998, p.33) says, ‘…The productive enterprise needs to make use of many
technologies besides the physical. These may be classified under the headings of commercial,
financial, and organizational technologies…’ A general way of incorporating the above
organizational inputs (OIs) in the production function is shown in the following equation.
Q= f (M, K, L, O, T) (1)
In this production function, all inputs (M: materials, K: capital, L: labour, O: OIs, T:
TIs) participate in the output Q in an autonomous way. Thus, changes in O cause changes in Q,
even if the other inputs do not vary. In addition, if we adopt the usual calculus results regarding
the marginal products of output with respect to each one of the inputs, we can obtain from
Lagrangian maximization of Q the cost or shadow price of each input.
9
Regarding the behavior of inventories, we just saw that on a micro basis we expect
from the LPS implementation that many firms and sectors achieve a continuous decrease in
inventories. This trend is also supported independently by other scholars who attempted to
theoretically understand the long term trend of inventories. Thus, Milgrom and Roberts (1990, p.
523) have shown through models of complementarities (as rigorously shown in their article) that
“…one expects to see a pattern of the following sort linking changes in a wide range of
variables:
Lower prices,
Lower marginal costs,
More frequent Product Redesigns and Improvements,
Higher Quality in Production, Marked by Fewer Defects,
Speedier Communication with Customers and Processing of Orders,
More Frequent Setups and Smaller Batch Sizes, with Correspondingly Lower
Levels of Finished-Goods and Work-In-Process Inventories and of Back
Orders per Unit Demand,
Speedier Delivery from Inventory,
Lower Setup, Wastage, and Changeover Costs,
Lower Marginal Costs of Product Redesign...”
The complementarities between all these variables are due to indivisibilities and hence
non-convexities. As these authors mention (ibid, p. 515) “these non-convexities then explain
why the successful adoption of modern manufacturing methods may not be a marginal decision”.
As these authors conclude, due to these complementarities the expected trend would be “to find
an increasing proportion of manufacturing firms adopting the modern manufacturing strategic
cluster that we have described” (ibid, p. 527). We will in our paper empirically check this trend
by adopting one of the most important consequences of modern manufacturing, that is, a long
term trend in diminishing inventories.
10
This trend is also related to the production smoothing as seen in LPS and JIT systems.
The objective of this smoothing “…is to reduce the variability of the production rate at the final
stage of manufacturing operations so as to create a stable demand stream for the other
manufacturing operations at the preceding stages. Therefore, production smoothing is a key
element of TPS, and, hence, a key component of the JIT philosophy…” (Yavuz and Akcali,
2007, p. 3580). Many techniques have been devised in order to achieve production smoothing
and hence efficient inventories planning within the context of LPS and JIT as Yavuz and Akcali
(2007) show in their article. Although production smoothing primarily examines volatility or
variance of production, it is nonetheless important to link production smoothing to inventories
and their trend to reduce over time (see also Morton et al, 1990; Konig and Seitz, 1991). Thus,
Morton et al (1990) conclude that subcontracting (a special feature of JIT) reduces the
variability of production and inventory. It is worth noting that Wen (2005, p. 1542) showed that
“…under the production smoothing motive, the covariance between inventory investment and
sales is negative at all cyclical frequencies…” This, at least supports the main consequence of
the LP cum JIT structures that as the sales increase in the long term, inventories decrease1.
Also on a theoretical level, Bils and Kahn (2000, p. 477) have shown that “...a persistent rise in
real marginal cost, absent intertemporal substitution, creates a persistent reduction in inventory
holdings relative to expected shipments”.
For a very comprehensive and recent treatment of input and output inventories
behavior in a general equilibrium macro-economic model, see Iacoviello et al (2010); these
authors relate the importance of LPS and JIT/QC in contributing to the persistent decline of
input inventories to GDP ratio through time. It is worth summarizing these authors’ findings
here because they provide strong theoretical and empirical evidence for our arguments. These
1 The author Wen (2005) did not have in mind these structures of LP and JIT, but it is not unreasonable to
deduct the above conclusion from his proposition.
11
scholars have constructed a dynamic stochastic general equilibrium model that takes into
account both input and output inventories, both goods and services sectors, depreciation, and
other desirable features of a comprehensive model. Input inventories (which are materials and
work-in-progress and constituting about 75% of total inventories) are very countercyclical,
contrary to output inventories which are mildly procyclical. As clearly shown in their graphs the
input inventories to GDP ratio has been steadily declining since about the mid 1980s in the USA.
Through Bayesian estimation methods, Iacoviello et al (2010) successfully capture the
countercyclicality of the input inventory to output ratio and found that the elasticity of
substitution between input inventories and fixed capital in the production function is much
smaller than unity. Through their general equilibrium model, the authors derive the steady-state
ratios of input and output inventories ratios which are a function of several parameters such as
the weight of input inventories in the CES aggregate, the elasticity of substitution, and so on.
These parameters are determined by “... new methods of inventory management like just-in-time
production or flexible manufacturing system...” (ibid, p. 7), which have been eminent since
1984 (p. 24). As the authors emphasize (ibid, p. 13), “...the prevailing view in the literature is
that a decline in (M+F)/Yg or M/Yg likely resulted from improvements in inventory
management and production techniques, such as “just-in-time” production, “flexible
manufacturing systems”, and “material resources planning”...” (M and F stand for input and
output inventories respectively; Yg stands for GDP)2.
There is considerable empirical evidence that on a micro basis, firms and industries,
through adopting LPS or similar production systems saw their inventories decreasing over a
long period of time, beyond business cycles fluctuations. Thus, Chen et al (2005) found that
2 The authors then quote several papers related to this statement.
12
American companies reduced inventories between 1981 and 2000 (see also Chen et al (2007)
for an extension of this conclusion to retail and wholesale industries). For a direct relationship,
Bo (2004) has found that inventory stock is negatively associated with fixed investment for
Dutch firms. For more evidence on a micro basis, see further below for more articles when we
examine the proxy for representing the LPS or JIT or similar systems. On a macro basis, Chikan
et al (2005), Chikan and Tatrai (2003), and Chikan and Kovacs (2009) have empirically shown
that inventories to GDP ratio decreases over time for many countries. These authors refer to the
LPS in order to explain this decrease. Williams (2008) and Elder and Tsoukalas (2006) brought
evidence of the declining inventories to GDP ratio in the UK.
3 Data, proxies, and econometric results
a) Data
Except for the institutional variables (they come from WGI) all other data come from
the World Development Indicators (WDI) database provided by the World Bank. The period
examined is from 1979 to 2008. The number of countries that report the data relevant for our
analysis vary from year to year. We obtained consistent data only for 69 countries (see Appendix
2 for the country list); low and lower income countries especially where their development does
not include a strong industrial sector are excluded on purpose, while countries with substantial
industrial production are included. However, some developing countries such as Vietnam,
Indonesia, Philippines, Tunisia and Ukraine are all included in the analysis, leading to quite a
balanced panel dataset.
Countries that are more likely to have lenan production were selected in our sample, as
this is what we are aiming at measuring; however, to check the robustness of our findings
against selection bias, we did analyze a larger number of countries (74) including very small
sized or island countries where lean production is unlikely to take place. We found similar
results in terms of the signs of IRIs’ coefficients and hence consistence with our results for 69
13
countries (the results for the 74-country sample are not shown here). Also please note that our
69-country sample contains both developed and developing countries, and thus with this mix of
nations we might be able to discern whether globalization of the LPS might be part of our
findings (if developed countries have lower inventories per GDP, then developing countries
might follow as well in this decreasing trend). Table 3 shows the summary statistics of the
control and target variables included in all our models.

b) Analysis for the proxy for LPS: the IRI or IRG
In our empirical work, we shall proxy “OIs” with inventories to sales ratio (ISR).
Although quality increases in tandem with decreasing inventories under the impact of LPS (see
14
for example Alles et al, 2000 for links between reducing inventories and increasing quality), we
do not have readily available a measure of quality improvement on a country basis. The proxy
ISR has been already established in literature as a good proxy for the JIT/QC or LPS. Thus,
Lieberman and Demeester (1999) who evaluate the relationship between inventory reduction
and productivity growth, conclude that JIT/QC system plays a considerably important role in
reducing its inventory level and improving the productivity level of a firm.
Furthermore, Nakamura M. and Nakamura A. (1989) viewed inventory/sales ratio as
main decision variables and mentioned “understanding inventory/sales ratio seems particularly
relevant since many US firms are beginning to implement the just-in-time production and
inventory system that some see as the key to the typically lower inventory/sales ratio of
Japanese firms.” Biggart and Gargeya (2002) wrote an article for the impact of JIT on inventory
to sales ratio and conducted their research on various types of inventories. They were
particularly interested in JIT system and found it really contributes to decrease the inventory
level of firms. Hence they found that total inventory to sales ratio and raw material inventory to
sales ratio significantly decreased.
More recently, Capkun et al. (2009) studied the relationship between inventory and
financial performance in manufacturing companies and they suggested that JIT and other types
of related techniques lower inventories and improve the productivity of the firms. They
mentioned that “recent research on the relationship between a managerial focus on improving
operations and performance has been concentrated primarily on JIT” and “the overwhelming
majority of studies show the positive effect of JIT implementation on earnings and financial
performance through the increase in productivity and inventory efficiency.” In addition, Irvine
(2003) observed the long term trends in US inventory to sales ratio and concluded that inventory
holding in the US has become much more efficient from the mid-1980s and this was the result
of adoption JIT and other inventory control systems by durable goods manufacturers.
15
Several other researchers use inventory to sales ratio as a proxy for JIT/QC
implementation. For example, Swamidass (2007) used inventory to sales ratio to see the effect
of Toyota production system (TPS) on US manufacturing during 1981-1998; Keane and
Feinberg (2005) and Dalton (2009) use inventory to sales ratio as a proxy for adoption of
improved logistics and JIT; Kros et al. (2006) used inventory turnover to measure the impact of
JIT inventory system on OEM suppliers. More recently, Sanidas (2011a) used the ISR as an
independent variable representing OIs (JIT/QC) together with R&D representing TIs to gauge
the positive impact of technology (both OIs and TIs) on 18000 Korean manufacturing firms’
growth in productivity. Sanidas (2004, 2005, 2011b) has provided further evidence of the impact
of ISR on American, and Korean sectors. Other important references of scholars having used the
inventory to sales ratio are Ramey and Vine (2004), Bairam (1996), and Salem and Jacques
(1996). In conclusion, it is established in the literature to use inventory to sales ratio as a proxy
for JIT/QC implementation and related OIs in research.
The above literature review shows that, on a micro basis there is evidence that ISR has
been decreasing in many firms and sectors in countries where the LPS has been implemented.
However, not all firms and not all sectors experience this decreasing long term trend (see for
example, Sanidas, 2011). Hence, there arises the following question: on a macroeconomic basis
what is the overall trend of the ISR? A priori we do not have a readily available answer,
although from the discussion in the previous section we saw that the overall trend is also
decreasing in some countries such as the USA. A side effect of our paper would be to check this
overall decreasing trend for several countries (of our sample).
Nevertheless, on a macro basis, we do not have a readily available series of sales in
order to construct the ISR. We will then use two alternatives for sales, namely, gross domestic
investment and GDP (as many other researchers have done so). We shall call “IRI” the
inventories to investment ratio and “IRG” the inventories to GDP ratio, defined as follows:
16
IRI jt= ΔINVjt−1 + ΔINVjt
GCF jt , and IRGjt=
ΔINVjt−1 + ΔINVjt
GDP jt, (2)
where INV3 stands for national inventories, and GCF
4 stands for gross capital formation, the
index ‘j’ stands for country, and ‘t’ stands for year.
Some basic descriptive statistics on IRI and IRG for the sample countries are shown in
Table 4. An important comment in this Table is that more developed countries have the tendency
to have a lower ISR (either IRI or IRG).

Figures 1A, 1B, and 1C show the yearly trend of IRI for selected countries such as the
developing China, India and Mexico, the Newly Industrialized Economies (S. Korea, Hong
Kong and Singapore) and the developed countries (United States, Germany and Japan); Figures
2A, 2B, and 2C show the corresponding trends for IRG. In these Figures we can see that IRI and
IRG are different according to a country’s economic development and growth. Thus we can
observe, for example, that even though IRI and IRG seem to be fluctuating along with business
18
cycles, most countries’ IRIs for the selected developed countries and NIEs have been drifting
downwards in the long run; exceptionally China’s IRI has been decreasing more substantially
(Naughton, 2007). However, Mexico and India’s IRI do not show much overall decreasing
tendency but on the contrary they have been increasing from the early 2000s.

In order to see more closely the link between the level of IRI and economic
development, Figure 3 shows a scatter-graph of IRI and real GDP per capita (taking the natural
logarithms of 5-year averages of lnRGPC) for the last period 2003-2008. As expected the two
variables are negatively correlated. The correlation coefficient between these two variables is in
the range from -0.12 to -0.43 depending on the examined period. High income countries tend to
have lower IRI while low-income countries tend to have higher IRIs. Figure 3 also shows that,
unsurprisingly, the IRI values for Germany (GER), United States (USA), Japan (JPN), South
Korea (KOR) and Singapore (SGP) are smallest since they are leading countries implementing
OIs and lean-production. Some emerging economics such as China (CHN), India (IND), and
Turkey (TUR) that used to have the largest IRI values in the first period (1979-1983) have
smaller IRIs in the sixth period (2003-2008) due to rapid industrialization and economic
development in recent years.

Table 5 shows regressions based on fixed effects (FE) model5. The random effects (RE)
model assume that individual country-specific effects are randomly treated (uncorrelated with
other regressors in the model) whereas the FE model relaxes this assumption and controls for
unobserved individual heterogeneity correlated with independent variables. However, since our
explanatory variables are not free from the endogeneity problem and violate the RE assumptions
in the regression, our conclusions are based on the FE model (in any case the Hausman test
confirms our choice of FE as being the right model to use). Hence, overall, as usually, the RE
model does not perform well in such cases. The time span used in these regressions is 30 years
(1979-2008) in terms of six periods (by taking 5-year average for each one of the 6 periods) as
previously mentioned. GDP growth rate is regressed on IRI, IRI lagged, IRI2, IRI
2 lagged, IRG,
IRG2 and control variables. The latter include initial per-capita GDP as a factor controlling for
the effect of the initial level of a country’s economic development. We also include investment,

education and population to account for standard factors of economic growth. Furthermore, to
control for other macroeconomic factors, inflation and year dummies are included in all
specifications6.
Regression shown in column (1) in Table 5 is our basic model without the effect of OIs;
it displays correct signs of coefficient for all variables in accordance with the literature. In
columns (2) - (7), we introduce IRI or IRI_lag and IRI2 or IRI
2_lag, as well as IRG and IRG
2.
The results show that IRI and IRI_lag have a positive and significant effect on growth. When
IRI decreases, growth rises and vice versa; in the case of IRI one-year lag (IRI_lag), we can
infer that the effects are larger based on the magnitude of IRI coefficients. Thus, the sign of IRI
or IRG coefficients is negative as expected. When the quadratic form of IRI is included, then it
shows a concave form, hence IRI still decreasing (in a ‘square’ way) in most of the interval of
the period examined (shown by the IRI2 term). On the contrary, the quadratic term of IRG is
insignificant, hence suggesting that IRG is a more linear representation of the LPS impact on
GDP growth than IRI is. It is also worth noting that models in column (6) and (7) exhibit the
highest R2, thus suggesting the quadratic significance of IRI’s impact on GDP growth.

Table 6 shows the results of GMM where we also included year dummies to control for
unobserved macroeconomic effects (not shown). Except for population (lnpop), all control
variables are treated as endogenous variables. The estimated coefficient of IRI or IRG is
significant and negative in all specifications and has a magnitude that is comparable to that in
the FE regression results. Overall, all coefficients are comparable in signs and significance with
those of FE regressions.

Due to lack of data for the entire 30-year period (used in our regressions) for the
variables R&D (RAD) and institutional performance (INS), the Hausman-Taylor (HT)
estimation method is applied. This method enables us to estimate the impact of TIs (as proxied
by R&D) and Institutions (INS) in the regressions7. Unsurprisingly, RAD and INS are
7 World Development Indicators (WDI) has consistent R&D data (as % of GDP) available from 1999 to
2008 and Worldwide Governance Indicators (WGI) cover the period from 1996 to 2009. Thus we took
10-year average of R&D expenditure and Institutional quality to be used in the HT model, which allows
us to have consistent and unbiased estimators through the use of instrumental variables technique. In any
25
significantly related with economic growth and the presence of these variables does not affect
much the statistical significance of IRI or IRG in the HT model. This suggests that IRI or IRG
works as a significant independent force on economic growth. The IRI or IRG has a negative
and large coefficient that is statistically significant in all specifications of the HT regression as
shown in Table 7. Overall, the results are similar to those with FE and GMM models.

4 Conclusion
We used 69 countries (both developed and developing), three econometric methods
(FE, GMM, and HT) for the period of 1979 to 2008. These regressions included several
standard explanatory variables plus the proxy for LPS which is inventories to investment or
inventories to GDP. Consistently, our results indicate that countries maintaining low inventory
level associated either with their investment or GDP level have a higher rate of economic
growth, even after controlling for initial development stage, physical and human capital, and
furthermore, institutional quality and technology levels.
As we explained already, the ratios of inventories to investment or inventories to GDP
represent or depict the new prevailing lean production system (LPS) of many industries in
various countries and especially in more developed ones. As an indication of the mechanism in
this system, countries with lower (higher) levels of IRI or IRG experience higher (lower) GDP
growth. Our results also show that the long run trend of decreasing inventories is strongly
associated with economic growth (this is inferred via our panel models). This association is the
main reason of the previous indication that IRI or IRG are lower in advanced countries than in
developing countries.
Furthermore, our results give us supportive evidence that the lean production system
(which is a major type of OI) has significant implications for effective economic performance.
Unnecessarily large inventories could be seen as a sign of failure in management and efficient
production. In brief, promoting OIs through LPS is crucial to economic growth. Thus, we need
to draw our attention to economic growth in terms of systems in production since recent
27
economic development takes place in situations where OIs are promoted in society and where
the increasing complexity of modern TIs and competitiveness is based more on institutional and
organizational capacity and human capital than on the abundance of natural resources or
physical capital. The implication from our findings is that the TIs, capital, labor and institutions
are not important independently in determining economic growth but are dependent on the
efforts of how countries appropriately organizing their resources.
