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.
