Abstract

In recent years, Korea had experienced two financial crises in 1997-1998 and 2007-2008 respectively and the IT revolution during the interval between the two financial crises. We have constructed Social Accounting Matrix (SAM) in 2000 and 2009 for Korea by combining Input-output tables used in WIOD project in Korea with data from 10-decile Urban Household Income Survey. We analyze gross income effect and income redistribution effect of financial crises and IT revolution by adopting a SAM framework following Pyatt and Round (2004) and Saari, Dietzenbacher and Los (2010). Both financial crises and IT revolution have generated larger income multiplier effect on Higher IT-intensive Manufacturing sector but have affected negatively on income redistribution of lower income groups.

1. INTRODUCTION Social Accounting Matrix (SAM) provides a useful framework to analyze the composition of national income and product and the process of income distribution. Even though SAM is a static analytical tool, we can examine the dynamic aspects of national income composition and its distribution by comparing two SAM over a time interval. We have shown in a recent report (Pyo, Kim and Lee (2011)) using SAM with the household micro cell by age group that exogenous injections of income to government mostly benefit the relative income of the pensioners, the age group over 60. The empirical result is consistent with that of Llop and Manresa (2004) who have found that exogenous injections of income to government mostly benefit the relative income of inactive households, which are mainly those of pensioners and have argued that such empirical evidence is important for policy making if the policies are aimed at modifying the distribution of income among economic agents. The purpose of the present paper is to analyze the impacts of IT revolution and two financial crises on the determination of national income and changes in the level of income of endogenous sectors through multiplier analysis and the structure of income distribution by constructing micro cell of household sector. As analyzed in Pyo (2000), the growth rate of real GDP which had averaged 7.1 percent during the pre-crisis period of 1993-1997 declined sharply recording – 6.9 percent in year 1998 when the so-called twin crises had hit the Korean economy. The financial crisis of 1997-1998 was called twin crises because there were both domestic banking crisis and foreign exchange crisis. As documented in Pyo (2004a) and Otsu and Pyo (2009), the macroeconomic adjustment during the post-crisis period was a successful one largely due to remarkable export performance helped by Won depreciation. During the period of 1998-2007, the export performance led by IT-intensive products has helped the economy to make a sustainable growth. When the global financial crisis occurred in 2007-2008, the recovery pattern of the Korean economy has been quite similar to the recovery pattern after the 1997-1998 crises. Korean Won was depreciated against not only US dollar but also Yen, Euro and Yuan and strong export performance in IT-intensive manufactures followed. We have attempted to analyze the impact of large scale depreciations immediately after two financial crises and export drive of IT-intensive products during the two post-crisis periods by multiplier and redistribution analysis based on SAM. For the purpose, we have constructed SAM for two discrete years of 2000 and 2009 in which we have treated Capital Accounts, External Accounts and Government Accounts as exogenous sectors and four-category production sectors as endogenous sectors:(1) Higher IT-intensive Manufacturing (2) Lower IT- intensive Manufacturing with Agriculture and Mining (3) Higher IT-intensive Services and (4) Lower IT-intensive Services following Ha and Pyo (2004) and Pyo and Ha (2007). We have also added a micro-SAM by decomposing the household sector to 10-decile units of income distribution by using KLIPS (Korea Labor Income Panel Study) dataset (1998-2008). There are major findings of the present study. The first finding is that the impact of both IT technology and two drastic depreciations have generated significant multiplier effects and redistributed income effects on Higher IT-intensity endogenous production sectors. The second finding is that the lowest income group (Unit 1) was the largest beneficiary group in terms of multiplier contribution and the highest income group (Unit 10) was the largest beneficiary group in terms of redistributed income effect. The last finding is consistent with the empirical finding by Llop and Manresa (2004) that injections of income to activities mostly benefit the relative income of the richest active households and the finding by Noh and Nam (2006).

In Section 2, we outline a SAM model of multiplier effects and redistribution effects. Section 3 presents empirical results after constructing SAM for the Korean economy of 2000 and 2009. The last section concludes the paper.

2. THE MULTIPLIER EFFECT AND RELATIVE INCOME DISTRIBUTION Following Roland-Holst and Sancho (1992) Llop and Manresa (2004) and Saari, Dietzenbacher and Los (2010), we can specify the multiplier analysis by dividing the accounts of a SAM into two separate sectors: endogenous and exogenous accounts as shown in Table 1. If we consider m endogenous sectors and z exogenous sectors, a SAM can be written as follows:

                                                               1

where Aij are partitioned sub-matrices that contain the expenditure share coefficients calculated by dividing the transactions in the SAM by the corresponding sum column. The multiplier analysis assumes that the expenditure coefficients are constant, so sub-matrices Aij assumed to be invariant over time. Income from endogenous accounts (Ym) can be obtained as follows from the top first row equations:

                    2

where I is the identity matrix, M = (I – Amm)-1 is a multiplier matrix and x = AmzYz is a vector of exogenous variables. The multiplier matrix M shows the overall effects of a unitary increase in the

exogenous components on the endogenous accounts. Therefore, the element ijm of M quantifies the

changes in the income of the sector I ( mdY ), i.e. gross income effect as a consequence of a unitary and

exogenous injection received by the sector j( mdY ).

From expression (2), the analysis of multipliers corresponding to endogenous sectors illustrates the changes in the absolute levels of income. Roland-Holst and Sancho (1992) presented an overall context for distributive incidence based on the SAM model. To identify the changes in the relative incomes2 of every endogenous sector, expression (2) can be normalized as follows:3

                                                       3 where e is a unitary row vector. From (3), the changes in the relative income of the endogenous

2 By relative income we mean relative to total income of all the endogenous accounts. 3 See Roland-Holst and Sancho (1992).

sectors generated by a modification in the exogenous injections are equal to: Table 1. Simplified Schematic Social Accounting Matrix4 Expenditures

In this expression, R is defined as the m by m redistribution matrix. It shows the change (positive or

negative) in the relative income of the endogenous sectors ( mdY ) caused by unitary modifications in

the exogenous injections of income received( mdX ). An individual element of this matrix, ijr ,

determines the magnitude (positive or negative) of the percentage change in the relative income of the sector i as a result of a unitary inflow in the sector j. This way of calculating the distribution process involves a set of bilateral connections between the endogenous sectors that tell us how one account influences the relative status of another. It is interesting that, irrespective of which endogenous components are chosen in the model, the sum of the columns in the matrix of redistribution is zero.5 This mathematical property means that the distribution process between the endogenous accounts can be interpreted as a game of winners and losers. If we take expression (4), we can identify three multiplicative components in the structure of R :

Page 5: The Impact of Financial Crises and IT Revolution on Income ... · financial crises and IT revolution have generated larger income multiplier effect on Higher IT- intensive Manufacturing

The first component, 1( ' )b e Mx , is the inverse of the total income of the endogenous sectors and

is a scalar. The second matrix, 1( ' ) ( ) 'D I e Mx Mx e , has two parts: the first part ( I ) is the

initial and exogenous injection of income that activates the multiplier process, and the second part 1( ' ) ( ) 'e Mx Mx e is the matrix of the initial relative income of every endogenous sector (with a

negative sign). Finally, M is the matrix of standard multipliers. Expression (5) represents matrix R in a multiplicative form and can be transformed into an additive expression. This transformation will make it easier to interpret the effects involved in the income distribution process. Specifically, we can define the redistribution matrix as follows:

                       6

This representation of R reveals the underlying components of the income distribution process and displays the sequential terms involved. In expression (6), b is the inverse of the total income of the endogenous sectors or the factor of normalization. The terms in the bracket show the initial and exogenous injection that starts the multiplier effect and the distribution process. Also, the matrix

( )I D tells us the endogenous sectors’ relative position. The last term in the bracket, ( )D M I ,

is the net multiplier effect on relative income and represents the additive contribution of the net

multipliers to the distribution process. Notice that ( )D M I contains the cross multiplier effects

among the endogenous sectors and its effects on relative income determination. An arbitrary element

( , )i j of this matrix, which can be either positive or negative, is equal to:

.     .

where ijmn are the components of the matrix M I of net multipliers and . jmn are the sum of

the elements of the j th column of M I . The multiplier contribution to income distribution is,

therefore, equal to its net multiplier minus the distribution generated by the account j to the other

endogenous institutions. The additive formulae of the redistribution matrix R clarify the direction and magnitude of the changes in the relative position of the accounts. Specifically the distribution procedure among economic agents when there are exogenous inflows of income is shown as the result of combining effects with different meaning. The initial and exogenous injection received by the sectors ( I ) affects

their relative status positively. The net multiplier effects on relative income ( )D M I have either a

positive or negative effect within the income distribution process. Finally, the initial relative income

of the endogenous sectors ( )I D contributes to the changes in the relative income negatively.

In particular, it is interesting to determine the contribution of the net multipliers (i.e., the matrix

( )D M I ) to income distribution because this provides information about the changes in the relative

position of the sectors as a result of the multiplier process. It is important to decompose the matrix of redistribution into different additive components. In our case we will see, through the elements of

Page 6: The Impact of Financial Crises and IT Revolution on Income ... · financial crises and IT revolution have generated larger income multiplier effect on Higher IT- intensive Manufacturing

matrix ( )D M I , a poor multiplier capacity for modifying the relative income of the endogenous

accounts.

3. Multiplier Effects and Income Redistribution Effects in Korea (2000 and 2009)

(1) Financial Crises and IT Revolution: An Overview

In order to assess macroeconomic fundamentals during the period of 2000-2011, we have decomposed production industries into 4 sectors as shown in Table 2: (1) Higher IT-intensive Manufacturing (2) Lower IT -intensive Manufacturing and Primary (3) Higher IT-intensive Services and (4) Lower IT-intensive Services following Ha and Pyo (2004) and Pyo and Ha (2007). We have summarized major final demand indicators (Figure 1), exchange rate and stock market index (Figure 2) and production and export performance by industries (see Table 3). The trend in final demand indicators clearly marks two points of financial crises in 1997-1998 and 2007-2008 when both real GDP and real investment fell sharply. After the two financial crises, export not investment had led the way for recovery. The movement in exchange rate (Won/dollar rate) shows large-scale abrupt depreciation of Won and drop in KOSPI stock index just after each financial crisis in 1997 and 2007. The decomposed industrial performances of output and exports over the period of 2000-2011 clearly indicate the strong performance by higher IT-intensity manufacturing with output growth (7.8 %) and export growth (11.9 %) respectively.

(2) Macro-SAM in 2000 and 2009 with Micro-SAM In order to identify multiplier effects and income redistribution effects for the period of 2000-2009, we have constructed SAM of Korea as shown in Table 4 for year 2000 and Table 5 for year 2009 by combining Input-Output Tables and National Accounts by the Bank of Korea in respective years. In order to construct a supplementary Micro-SAM, we have used Korea Labor & Income Panel Study (KLIPS) Database (1998-2008) to decompose household sector into 10-Decile units. They are presented in Table 6 for year 2000 and Table 7 for year 2009 which show sources of income (wage, profit, business transfer, government transfer and foreign transfer income). When we compare Table 6

Page 9: The Impact of Financial Crises and IT Revolution on Income ... · financial crises and IT revolution have generated larger income multiplier effect on Higher IT- intensive Manufacturing

with Table 7, the income distribution of profit has been markedly skewed in favor of higher income deciles. For example, 40.5 percent of the profit income was distributed to the highest income decile (Unit of 10) in 2000 but 52.7 percent in 2009. On the other hand, the business transfer income moved to the opposite direction; the highest income decile received 73.9 percent in 2000 but only 45.4 percent in 2009. In general, the distribution structure of gross income by 10 deciles changed in favor of lower income groups. The ratio of upper 20 % income to lower 20 % income was 17.1 in 2000 and 12.1 in 2009 respectively. The wage income of the lower income deciles (Unit of 1 and 2) was only 3.1 percent in 2000 but improved to be 3.7 percent in 2009. It was mainly due to the welfare policies for the lower income groups by President Kim (1998-2002) and President Roh administration (2003-2007). On the household expenditure side, we have used 2001 KLIPS data for Micro-SAM (2000) and 2008 KLIPS data for Micro-SAM (2009) as shown in Table 8 and 9 respectively. In general, the distribution structure of gross expenditure by 10 deciles changed in favor of lower income groups too. The ratio of upper 20 % expenditure to lower 20 % expenditure was 4.5 in 2000 and 3.6 in 2009 respectively. The gross expenditure of the lower income deciles (Unit of 1 and 2) was only 8.3 percent in 2000 but improved to be 10.1 percent in 2009. Because of differences in survey items between 2001 KLIPS data and 2008 KLIPS data, we had to use the same proportions of income and expenditure in both 2000 and 2009.

(3)Multiplier Effects In both Table 10 and Table 11, we have shown multiplier income effects on four sectors of industries, (1) Manufacturing with low IT-intensity, (2)Manufacturing with high IT-intensity, (3)Service with low IT-intensity and (4)Service with high IT-intensity. The row average of each table represents average sensitivity of the sector when expenditure is injected from each of four sectors. In both Table 9 and 10, the multiplier effect is highest with the Sector (2) and lowest with the Sector (3). By comparing two tables, we can see that each sector’s income multiplier sums in all four sectors have become larger in 2009 than in 2000. The sector (3) Service with low IT-intensity had the lowest average sensitivity, 0.433 and 0.411 respectively. Therefore, we can conclude that sector (3) Service with low-IT intensity has both the lowest average sensitivity and the lowest income multiplier effect, which is a typical nature of the non-tradable service sector.

In Table 12 and 13, we have summarized multiplier contribution of production to household income by 10-decile groups. In both 2000 and 2009, total multiplier contribution was highest in sector (3) lower IT-intensity service sector such as Construction, Transportation and Storage, Real Estate and Government. These industries have lower intermediate inputs and higher value-added and therefore, when the production activity increases, the income generation through multiplier effects is relatively larger than other sectors. In general though, the multiplier effects of production to household income have become smaller in 2009 than in 2000. In addition, we can point out that the average sensitivity by each unit of household is larger as we move to upper income units. It also became smaller in 2009 than in 2000.

In Table 14 and 15, we have presented inter-household multiplier contribution to income in 2000 and 2009. It shows that when an income is injected into the lowest income unit (Unit of 1), it has the largest income effect. The effect becomes smaller as we move toward higher income deciles. It is not a surprising result because the consumption expenditure to income increase is more sensitive in lower income brackets than in higher income brackets. On the other hand, if an equal amount was injected across all units of income decile, the highest income unit gains the most. It should also be pointed out that the column sum of two tables, Table 14 and 15, is the largest in Unit of 1 in both 2000 and 2009. This is because the lower income groups pay lower taxes and pension contributions while they tend to have higher propensity to consume. Since the government sector is regarded as an exogenous account and the higher income groups pay higher taxes and pension contributions, their propensity to consume will be less than lower income groups. On the other hand, average sensitivity becomes higher as we move from lower income units to higher income units in both 2000 and 2009. It indicates that higher income units derive higher multiplier effects and marginal benefits.

(4) Redistribution Effects When there is income generated by one account, the income generated is distributed not equally to each sector and it becomes a zero-sum game. We can analyze how income generated by each production sector gets redistributed across different income units of household. For example, we can identify the induced production activities of four endogenous sectors by increased final demand in three exogenous accounts. Then we can trace how the income generated in endogenous sectors gets redistributed among household income units. Table 16 and 17 is the matrix of such redistributed income which sums up to zero. The result is different from multiplier effects. When income is generated from the entire production sectors, the Higher IT-intensity Manufacturing sector has the lowest income redistribution effect. In particular, the sector’s redistribution effect became negative (-1.019) while all other three sectors have had positive redistribution effects. On the other hand, when income is injected to production activity, the lower IT-intensity Service sector has the lowest column sum like the sector’s multiplier effects and it became lower in 2009 than in 2000.

Table 18 and 19 are the results of redistributed income effects of production activity in four sectors on household income by ten income units. In both 2000 and 2009, the lower IT-intensity Service sector has generated the largest total income redistribution effect (0.034 and 0.081). In terms of average sensitivity, the highest income group, Unit 10, has had the largest negative sensitivity (-0.040) in 2000 but it became the only positive sensitivity (0.002) in 2009.

Lastly we examine the redistribution effect of household income injected on household income redistributed among different income units. Table 20 and 21 are redistributed household income among different income units in 2000 and 2009 respectively. In general the total effects are positive across all income units. But within each unit, the redistribution effect is positive only to itself and negative in all other sectors. In other words, the redistributed income matrix of households has positive diagonal elements but all negative off-diagonal elements. The total redistribution effect is the largest in the highest income unit and became smaller as we move lower income units in both 2000 and 2009. The total effect was larger in 2009 than in 2000 across all units. On the other hand average sensitivity moved in the opposite direction becoming lower as we move from lower income units to higher ones. It implies when income is injected to household account, the higher income units derive higher redistribution effects. On the other hand, the redistribution effect becomes more sensitive with lower income groups because their income level are at lower level and therefore, they are affected marginally more. It is noted that average sensitivity of Unit 10 was negative (-0.002) in 2000 but it became positive (0.049) in 2009 which implies after the global financial crisis of 2007-2008, the highest income unit (Unit 10) has become net gainers than net losers in redistribution of household income.

4. CONCLUSION

In the present paper, we have examined the impact of two financial crises and IT revolution on multiplier effects and redistribution effects of both production sectors and household income units in Korea for the period of 2000-2011. We have decomposed the entire production activities into four sectors by the ranking of It-intensity. As a consequence of depreciation in the post-crisis periods, there was a strong export performance in higher IT-intensity Manufacturing Sector. This has generated a strong exogenous impact on four endogenous sectors of production. It also has generated income redistribution effects among different sectors of production and across different income units. In general, the distribution structure of gross income by 10 deciles changed in favor of lower income groups. The ratio of upper 20 % income to lower 20 % income was 17.1 in 2000 and 12.1 in 2009 respectively. The wage income of the lower income deciles (Unit of 1 and 2) was only 3.1 percent in 2000 but improved to be 3.7 percent in 2009. It was mainly due to the welfare policies for the lower income groups by President Kim (1998-2002) and President Roh administration (2003-2007). In analysis of multiplier effects, we have found that the sector (3) Service with low IT-intensity had the lowest average sensitivity, 0.433 and 0.411 respectively. Therefore, we can conclude that sector (3) Service with low-IT intensity has both the lowest average sensitivity and the lowest income multiplier effect, which is a typical nature of the non-tradable service sector. On the other hand, the multiplier effects of production to household income have become smaller in 2009 than in 2000. In addition, we can point out that the average sensitivity by each unit of household is larger as we move to upper income units. It also became smaller in 2009 than in 2000. In analysis of redistribution effects, the lower IT-intensity Service sector has generated the largest total income redistribution effect (0.034 and 0.081) in both 2000 and 2009,. In terms of average sensitivity, the highest income group, Unit 10, has had the largest negative sensitivity (-0.040) in 2000 but it became the only positive sensitivity (0.002) in 2009. In general the total redistribution effects are positive across all income units. But within each unit, the redistribution effect is positive only to itself and negative in all other sectors. In other words, the redistributed income matrix of households has positive diagonal elements but all negative off-diagonal elements. The total redistribution effect is the largest in the highest income unit and became smaller as we move lower income units in both 2000 and 2009. The total effect was larger in 2009 than in 2000 across all units. On the other hand average sensitivity moved in the opposite direction becoming lower as we move from lower income units to higher ones. It implies when income is injected to household account, the higher income units derive higher redistribution effects. These finding provide evidence increasing globalization of production activities in Korea and IT-intensity deepening has generated more redistribution effect in favor of higher income units. However the overall indicator of income disparity has not been worsened between 2000 and 2009 after two financial crises. When we measure it as the ratio of upper 20 percent income divided by lower 20 % income, the income disparity has been narrowed.
