Understanding partial mergers in Japan

Since the late 1990s, Japan has witnessed a substantial increase of partial mergers where two or more firms spin off whole operations in the same business and combine them into a joint venture (JV). This paper provides the first academic evidence on this phenomenon. I find that partial mergers normally occur as a response to negative economic shocks by firms that are larger and more diversified than firms in total mergers. An event study identifies positive and significant returns to partial merger announcements. Unlike total mergers whose value accrues mostly to the shareholders of small (acquired) firms, large and small firms in partial mergers receive comparable returns, which are particularly large to firms forming an equally owned JV. This study also finds that partial mergers are often ex post transformed, with equity sale between partners being the main source of change.     

R&D intensity and acquisition and divestiture of corporate assets: Evidence from Japan

This article provides evidence from Japanese acquisitions and divestitures after the late 1990s on the effect of corporate R&D to stimulate inter-firm asset trade. Consistent with the notion that R&D increases a firm's opportunities for and ability to profit from synergy with external assets, regressions performed on a sample of publicly traded manufacturers reveal that R&D intensity and the breadth of patented technologies positively and significantly correlate with a firm's probabilities to acquire and sell off assets. The link of R&D and divestiture is qualitatively homogeneous across industries and time but the positive and significant R&D-acquisition link concentrates in industries where the interdependence of firms’ innovative activities is relatively high and time when firms likely had large pent-up demand for asset trade.     

The effect of changes in Japanese consolidation policy on analyst forecast error

Our broad research objective is to investigate whether convergence towards international standards improves the decision usefulness of information. Recent changes in Japanese consolidated reporting practices to better align with international standards provide an excellent setting to investigate this research objective. Specifically, we examine the effect of changes in Japanese consolidation policy on financial analysts’ perceptions of the persistence of subsidiary earnings. Previous research provides evidence that, prior to the change in consolidation policy, consolidated financial information was not used efficiently in the Japanese capital market. Prior research finds a positive relation between subsidiary earnings and future stock returns in Japan, indicating that investors underestimate the persistence of subsidiary earnings. Consistent with prior research using stock returns, we find that financial analysts also underestimate the persistence of subsidiary earnings in Japan. We document a significant positive relation between subsidiary earnings and future forecast errors of consolidated earnings. However, following the changes in consolidation policy in Japan, we find that financial analysts no longer underestimate the persistence of subsidiary earnings. Changes in Japanese consolidation policy in conformance with international standards increase decision usefulness by improving the ability of financial analysts to predict overall firm performance. One limitation of our research design relates to the adoption of mandated accounting policy changes by all sample firms in the same calendar time. This makes it difficult to control for the impact of correlated omitted variables. While this concern can never be completely eliminated, we provide additional tests that examine sample partitions by firm size and industry. These additional tests support the primary findings that Japan’s efforts to converge consolidation rules with international standards have improved analysts’ consolidated earnings forecasts.     

FLEXIBLE COST FUNCTION ESTIMATES FOR A GAS AND FUEL CORPORATION IN AUSTRALIA

This paper reviews and empirically tests the available evidence concerning economies of scale and technological change at Australian Gas Limited of New South Wales (AGL). a gas and fuel corporation. Since energy corporations are considered to need scale economies, they are regulated 'n both developed and developing countries. In keeping with the trend of deregulation stemming from the beginning of the 1980s in Western countries, many kinds of public corporations have been privatized and deregulated. Energy corporations are not an exceptional case, but very little evidence on this industry has been reported so far. From empirical tests, it is shown in a trans-log-type cost function that AGL has scale economies. the degree of which increased after the corporation changed its energy source from coal oil to liquid natural gas. Moreover, from the results of the trans-log cost function including technological change, a Hicksian neutral type technical progress exists. In a Hicksian non-neutral type, stock-intensive technical progress exists. while labor productivity deterioates. Energy productivity is not significant.     

Diversification,Organization, and Value of the Firm

Because corporate diversification coevolves with organizational structure, a discount for diversification, which is widely documented in the literature, can be caused by organizational structure rather than by the industrial scope of the firm. I examine this possibility based on a large sample of Japanese firms for which the legal (parent–subsidiary) structure of the organization is easily observable. I identify a significant discount for diversified firms with and without control over the organizational structure. I also find that firms with a legally segmented structure (e.g., holding companies) are deeply discounted. My results suggest that diversification and organization are both important determinants of firm value.
