The Performance of Japanese Companies - A Growing Connection with External Demand

Last week, we learned that industrial production rose yet again in Japan clocking in at 1.4% month-on-month in September after having increased by 1.6% in August.

Companies said they planned to increase production in October and November as well, indicating the recovery from a record export collapse in the first quarter is holding up. Growth in China is generating sales for manufacturers including Hitachi Construction Machinery Co., which this week said it has worked off stockpiles that piled up during the recession.

“The pace of the recovery is faster than expected,” said Hiroshi Miyazaki, chief economist at Shinkin Asset Management Co. in Tokyo. Withdrawal of stimulus in the U.S. and Europe may cause output and exports to slow down this quarter, Miyazaki said, “but so far, today’s production report showed few signs of that.”

This is good news for Japan's economy even if it seems that Japan may simply be re-deploying old tricks in which companies are leveraging external demand but the domestic economy remains unable to pick up on the momentum. As ever, the disconnect between the level and flow of domestic activity (and price pressure) created by the domestic economy and the additional boost from external demand and asset income remains one the main perspective through which to look at the Japanese economy.

Within this context, the notion of Japan being dependent on exports to grow has emerged; initially as a strong market discourse and since in a more formal theoretical light in the form of the humble contribution of yours truly. It still represents a powerful market discourse and in fact, the idea of export dependency or reliance on external demand has been propelled to the main scene of the current economic turmoil as it has slowly but surely dawned on market participants and policy makers that the extent to which global imbalances need to be resolved, we have to find someone to run the deficits. And although this may seem a simple task, it has proved decidedly difficult to make the puzzles match in a world where deleveraging remains a key driving force on both the microeconomic and macroeconomic level.

In this entry I thought it would be interesting to look at a topic which combines the two perspectives above, that is; both the theoretical and the more market oriented narrative. On the former, this analysis would seek to move the analytical perspective down a notch from the pure macroeconomic level to a microeconomic level linking data on the company level (company accounts) with macroeconomic data (national accounts). On the latter, the analysis would provide some empirical foundation for the often cited relationship between a positive reading on industrial production/capex and a pick up in external demand, or more precisely the link between corporate activity and exports.

The analysis will be based on data from the Japanese trade ministry (METI) and OECD and will cover the period 1960Q1-2008Q4 (mail me for the excel sheet). On the company side, I will use data on sales (topline) and as well as profits (operating and ordinary). I will also distinguish between the manufacturing and non-manufacturing sector since one might expect, in Japan's case, the accounts of the former to be considerably more sensitive to external demand than in the case of the latter. With respect to national accounts I am using the OECD CARSA methodology which essentially signifies that we have current prices at annual levels with seasonal adjustment.

In line with the spin traditionally served here at Alpha.Sources, I will be looking at an increase in the connection between corporate sales and profits and external demand as an implicit function of age. This is to say, that this disconnect between domestic momentum and the ability of Japanese companies to generate revenues and thus growth based on external demand is a function of the increase in Japan's median age.

The main results of the analysis can be summarized in the following points.

• The positive relationship between the change in Japanese companies' profits/topline and the change in exports or the current account has increased markedly in a post 1990 and specifically post 1998-2000 context. This effect is predominantly a phenomenon observed amongst manufacturing companies.

• The empirical analysis suggest that Japanese manufacturing companies are now highly reliant on external demand to generate sales, profits and thus in some sense investment activity.

• The sensitivity of the sales of manufacturers to the volume of exports has increased by a factor of 60% from 0.25% to 0.4% around the period where Japan breaches a median age of 40 years.

• The sensitivity of the ordinary profits of manufacturers to the current account has equally increased markedly in the period where Japan has moved to a median age above 40. In the period after 1997 results indicates that a 1 unit (JPY) increase in the change of the current account has led to a 0.23 unit (JPY) increase in the ordinary profits of Japanese manufacturers which compares with a corresponding non-significant relationship in a pre 1998 context.

A Look at Company Performance, the Current Account and Correlation

Regardless of whether one squares the outlook on the Japanese economy, there is no doubt that the dent which the corporates have taken as a result of the economic turmoil is unprecedented.

Notice that I have indexed the charts with 1995 as a base year and then realize that current nominal value of company revenues has dropped to a level comparative to the one observed in 1993-1994 in relative terms. In absolute terms, the aggregate value of sales of Japanese manufacturers stood at some tn 84 and 82 JPY in Q1-09 and Q2-09 respectively which is value not observed since 1989 in nominal terms. This should give us a clear picture of drop in activity and then also the difficulty with which Japan will have in restoring productive activities back to normal whatever this might mean as we move forward.

With respect to Japan's external balance it is a bit more complicated, but there are some important points to remember as we move through the charts. Japan has been running an external surplus since the beginning of the 1980s, but as I have spent an entire academic paper explaining, it is only in the latter part of the 1990s and into the 2000s that this external surplus seems to be connected strongly with output growth. Moreover, it is important to distinguish between net exports and the income balance since the latter has been particularly important driving Japan's external balance in a from the 1990s and onwards

In light of the graph above, we can say that given the sharp decline in domestic growth in a post 1990 context external demand has take over, so to speak, both in terms of keeping national savings higher as well as contributing to headline growth. It is along the same axis that we would then expect the relationship between Japanese companies and external demand to have increased.

Moving on to some simple correlation analysis the following two charts which show the correlation between company sales and exports as well as the trade surplus/GDP will give us a nice initial overview of the data in question.

The representation is in changes (which is not unimportant) and smoothed by taking the correlation as a 4 year moving average (i.e. 16 quarters). The y-axis is ending period which means that a correlation for e.g. 1997 means correlation between 1993-1997.

Simply eye balling these charts does not seem to provide decisive evidence of the hypothesis of export dependency. Sure, we can easily see that the period 1997-2008 has seen a sharp increase in the relationship between company sales and the flow of exports as well as the share of external demand and GDP, but the key point to take away from these graphs is that they appear to be mean reverting (with a very weak positive time trend in the case of the second). This would mean then that the connection currently observed between exports and corporate sales is not unique. However, if we focus the attention on the second graph, it is also pretty clear that it is only in a post 1980 context that we have observed periods in which the correlation between sales and the trade surplus has been consistently and strongly positive. This would then seem to lend some evidence to the idea of export dependency and how this may be a distinct characteristic of contemporary Japan.

Moreover it would seem that it is not possible (except in the case of the correlation between sales and the trade surplus) to distinguish decisively between manufacturing and non-manufacturing. In later sections and using simple ordinary least squares analysis, it is however possible to differentiate this statement considerably.

Before we come to that though, it would be apt to use the initial conclusion above and have a closer look at the post 1980 period. Moreover, and courtesy of a more richer dataset on the macroeconomic level we can now augment the analysis with the income balance and thus the current account. This may seem trivial, but is very important in Japan's case since the income balance in particular has driven the external balance in recent years. From a company point of view and in order to be consistent, I will correct for the importance of the income balance by including company profits as the main gauge for company performance.

This chart (in level form and only for manufacturers) seems to be more supportive of the evidence of export dependency at least if we allow ourself the luxury to look only at the period from 1980s. The chart shows however that the strong positive relationship between the current account and the profits of companies is a relatively recent phenomenon which took off somewhere around 2000. Consequently, in the period from 1983 to 2000 the correlation between the current account and company profits in the manufacturing sector has been negative and in some cases strongly negative.

From this brief look at correlations, we should be satisfied that when it comes to the period post 1998 (more or less) the performance of Japanese companies have been strongly linked to external demand and income derived from external assets. Yet, this does not provides decisive evidence for export dependency measured as a strong and growing link between the performance of companies and external demand. In order to show this we must turn our attention to a bit more sophisticated statistical techniques although I can promise you that it won't be very fancy.

Some Models to Go With That?

The analysis which proceeds will center on the two following simple models which take the first difference or percentage change as a linear function of the change in either the value of exports or the current account.

The first regression will also be run with the sales of non-manufacturers as dependent variable in order to check the initial conclusion above that it is really not possible to distinguish between manufacturers and non-manufacturers[1].

Now, if you don't care about statistical analysis, you may stop here and move straight to the conclusion or go back to the summary in the beginning where the main results are reported. If you decide however to move on, rest assured that, following the models above, I never move beyond univariate OLS, so things should not get too complicated if you are a little bit familiar with statistical analysis.

Note that throughout, the full period will be Q1 1960 to Q4 2008, period 1 signifies the period where Japan had a median age below 40 and period 2 is consequently defined as the period in which Japan had a median age above 40.

If we begin with the first model that plots sales of manufacturers as a linear function of the volume in exports (both in % changes), the results for the full period, period 1, and period 2 regressions return the following results [2].

For those of you who are familiar with the results presented in my earlier work on Japan, these results should be well known. In this way, it appears that the relationship between the sales of manufacturers and the volume of exports has increased markedly, both in terms of the marginal effect as well as in the context of the overall fit of the model. Since this model is a log-log model, we can interpret the coefficient in percentages and in this way, the estimation indicate that the sensitivity of the sales of manufacturers to the volume of exports has increased by a factor of 60% from 0.25% to 0.4%. In words, it means that in the second period the estimation suggests that a 1% increase in exports will lead to a 0.4% increase in the sales of manufacturers whereas the corresponding number is 0.25% in period 1.

Looking at the overall fit of the relationship, the results clearly indicate that this representation leaves out a considerable source of the variation in the sales of manufacturers which is entirely to be expected. As always, it is essentially a qualitative and theoretical question whether the increase in the sensitivity as well as the goodness of fit (from 0.08 to 0.13) represents de-facto export dependency or simply indicates an increased reliance over and above other more important factors.

In relation to the second model which plots operating profits as a linear function of the change in the current account, it is important to note that this model is estimated in the first difference (and thus not log-log) because the current account in some cases has been negative. Moreover, the sample period is shorter than for the first model (1980-2008) since OECD does not have data for the income balance prior to 1980.

On an overall basis these results underpin those from the first estimation although they seem to confirm the hypothesis to a much higher degree. Abstracting from the full period result which serves as an anchor for the overall significance of the relationship, the difference between the model estimated for period 1 and period 2 is striking. Consequently, the first period estimation signifying the period where the median age of Japan is below 40 shows no significant relationship whatsoever, in this sense it appears that the apparent negative relationship implied above from the correlation charts do not pass the simple causality test which OLS represents. The second period regression on the other hand returns a strong and significant relationship which indicates that a 1 unit (JPY) increase in the change of the current account will lead to a 0.23 unit (JPY) increase in the ordinary profits of Japanese manufacturers. On the goodness of fit measure the only thing we can say is that it has increased considerably to signify the increase in relationship between the profits of manufacturers and the current account. However, whether a goodness of fit of 0.15 is high in an absolute sense here is difficult to say without a more thorough and comparative study. But since we have a univariate framework, I believe this result to be quite extraordinary.

Conclusion

I hope by now that I will have either convinced you or scared you off in terms of the importance of whether Japan is dependent on exports to grow or not. I would also hope that the connection to events closer to the market is not too difficult to see. For example, Bloomberg is running the story today that the BOJ, like most other central banks, is either willingly or, dragged kicking and screaming by market sentiment, moving towards the formulation and near execution of the famed exit strategy from extraordinary monetary policy measures. Clearly, interest rates are to remain low for as far as the eye can see, but it is interesting to ponder whether the decision by the BOJ scale back corporate debt purchases is related to optimism on the companies ability to leverage domestic growth or whether it is because they see export markets reving back up in which case it would be back to the same old growth strategy. Another example would be the latest inflation reading which suggests, more than anything, the extent to which the domestic economy in Japan is not able to provide an environment in which companies can operate profitably as well as it indicates how overall domestic momentum is essentially contractory.

It is within this general economic context that the notion of export dependency becomes important and specifically how this might relate to the ageing of Japan's population. In this entry I have tried to take this idea down a notch from the strict macroeconomic level in the form of an analysis of the relationship between external demand measured through national accounts and aggregate corporate accounts. The results, I believe, speak for themselves and strongly suggest I think that Japan indeed is becoming increasingly dependent on external demand to create the growth and income the economy needs to maintain economic growth. Following from this, a number of questions present themselves, not least the most crucial general question relating the issue of export dependency to ageing in a general sense and then on to the discourse on global macroeconomic imbalances. But for now, I will let you digest the data at described and analysed above.

Japan - In the Eye off the Beholder

By Claus Vistesen: Copenhagen

After a nice and entertaining week in Barcelona where I had the privilege not only to hold a seminar at the Universitat Autònoma de Barcelona, but also to meet a host of interesting people, I thought that it would be about time that I finished my piece on the latest data from Japan which admittedly will be a bit backward looking, but hopefully interesting nonetheless.

Beauty, as they say lies in the eye of the beholder and perhaps this axiom is worthwhile contemplating when thinking about the immediate condition of the Japanese economy or indeed the global economy and her asset markets, but for the sake for simplicity . Consider for example the news, out a week ago, that Japan's current account surplus widened 10% in August over the year. In an economy where external demand is the main driver of economic growth, this is a significant piece of news and should rightly be interpreted as a positive sign. Or should it?

Once we read beyond the immediate headlines it becomes clear that what we are really seeing in Japan is, in fact, a pendant (even if less severe) to the Spanish situation where the improvement in the external balance comes, not from a sustained and independent pick-up in external demand, but rather from the fact that domestic demand is contracting faster than external demand thus pushing up the current account. In Japan, exports slid 37.1% on the year but as imports shed a corresponding 41.2%, the current account improved as a result. Naturally, some would want to insert the point here that since Asia (and in particular China) seem to be the locus of small, but definitely noticeable, upbeat signs in the global economy, Japan should be at the forefront to snap up the gains. Surely this is true, and one wonders how far exports would have tumbled on the year if China had not been there to pick up the slack; yet, as we can see from the figures above; the downward momentum remains in spit. It seems, that beauty indeed is a subjective concept.

With respect to the most recent event as it were in the Japanese economy, the BOJ meeting held last week did not really bring much new to the table with respect to policy measures as rates were kept in QE mode. However, and as Societe Generale's Gleen Maquire points out in a recent publication (the weekly monitor) the point is moving closer with respect to whether the BOJ will extend its extraordinary credit measures or stop them. This would then be a discussion about the much debated exit strategies by part of especially the G3 central banks; how it will be conducted and equally as important when. The current message seems to be that while it is difficult to see the BOJ abandoning ZIRP any time soon, the BOJ is not going to extent the current measures of credit support in the form of the purchase of corporate bonds and commercial paper as well as a special funding program for corporate finance facilitation from the point of view of banks. As Maquire correctly points out and regardless of whether ZIRP is set to continue or not, a withdrawal of these measures would naturally represent a de-facto policy tightening and it is unclear just what the effect will be on the Japanese economy.

Moving on to a piece by piece look at the recent monthly data, August's numbers did bring with it a bit of light (September number will be out at the end of October) although the fundamentals have hardly changed.

Kicking off with domestic consumption, the headline figure reported by the statistical office clocked in a nice increase of 2.6% y-o-y which is of a magnitude not seen since January 2008. It is interesting to differentiate the headline figure of 2.6% (which is a real figure) is in somewhat stark contrast to the nominal decline in the consumption of workers' households of 1.4%. At this point, the average monthly change on an annual basis for the overall consumption index in Japan is -1.2% (up from -1.8% before the 2.6% figure reported from August); I will hold off any premature conclusions of a sustained pick-up in consumption before seeing what is in store in the coming months.

With respect to prices, Japan now looks thoroughly entrenched in deflation;

The general core index thus declined 2.2% over the year with the core-of-core index declining 2.6%. So far in 2009, the core-of-core index has declined 8.3% with an average monthly decline of 1%. This is a strong testament to the strong downward momentum in the domestic economy and underpins the following very reasonable assessment by Glenn Maquire;

Realistically, it will be very difficult for the Bank to forecast positive inflation over the next two to three years. The Consumer Price Index continues to fall sharply and the output gap remains extraordinarily large by any metric. With the yen now appreciating and political opposition to a stronger yen having passed with the Liberal Democratic Party losing power, Japan is likely to remain more at risk of deflation than inflation over the entire period including calendar 2012.

Especially the point on the output gap is important even if we don't observe this specific data point. I would add the qualifying comment that one thing is the size of the output which in some sense would signify the immediate damage incurred by the Japanese economy in the context of the financial crisis and another thing is the speed (and ability) with which Japan can close this output gap on the basis of domestic activities alone. A point that I would especially emphasise here is the simple fact that the potential growth rate of Japan is likely to be in an almost perpetual decline due to the demographic situation. In this sense, it may increasingly become a question of what in fact the potential growth rate is based on domestic activity (i.e whether it is positive at all) than a matter of closing the output gap.

On the labour market, things improved rather surprisingly in August with the unemployment rate declining from 5.7% in July to 5.8% in August.

In the context of the financial crisis, the unemployment rate has so far increased roughly 2% and although the number in no means is alarming in a relative sense, the prospect of a continuing increase is sure to make cautious consumers even more cautious.

Turning finally to the corporate sector, industrial production has recovered somewhat after the absolutely horrid decline observed in the first half of 2009. The question is the extent to which we should see this as a decisive positive sign or not.

Once again, this is a matter of interpretation but when for example the Swedish bank calls it a "new dawn" for industrial production after looking at the graph above I find it difficult to see exactly where this dawn is. Consequently and while it is certainly true that the index for industrial production has recovered some ground after bottoming out in February 2009, it is still situated 18.3% lower than its average value (measured from January 2003 to July 2009). This compares with an index for all industrial activity running some 7% below its historical average. These numbers are innocuous in themselves, but the important thing is the level of activity which can be supported by the Japanese economy and although we are certain to see some recovery in the data the underlying momentum may ultimately disappoint.

The chart above taken from JPMorgan's Global Datawatch is perhaps the clearest picture of what export dependency means in the case of Japan and how it drives the level of industrial activity.

With respect to the Tankan, the survey showed a pick up in sentiment which follows leads nicely the pick up in real economic activity. Pessimists still outweigh optimists by a rather large margin and it shall be interesting to see whether the apparent (and indeed lingering) positive sentiment among global market participants will spill over forcefully into expectations and investment plans moving forward.

Summary - A Beauty or a Beast?

Some of you may feel that I am spinning the story of Japan too much towards the negative sign. I don't believe this is the case however, and although I can see that some positive signs have emerged, I remain skeptical that it will be enduring. Call me a permabear, but 3-4 years of Japan watching has taught me to be careful when it comes to emphasizing positive news on the Japanese economy, and especially so when it comes to the momentum of the domestic economy.

This brings us to the global economy and the simple fact that the extent to which one would narrate the outlook on the Japanese economy in relative positive light would be tantamount to the extent that one also sees a relative benign outcome for the global economy. Here I am also skeptical which is ultimately also why I remain cautious on Japan and especially so in an environment where the JPY does not seem to benefit from low volatility and risk proneness to the same extent as before the Fed engaged in QE. But that is certainly a discussion for another day; for now, I will leave you my dear reader with the judgement on the immediate outlook for Japan's economy remembering full well that beauty indeed lies within the eye of the beholder.
