Interindustry effects of productivity growth in Japan: 1960–2000

Combining conventional sectoral growth accounting and the static open input–output price model, we analyze the sources of growth of product prices in Japan during the period 1960–2000. Using the input–output framework, we take into account not only the effects of factor costs and productivity within a sector, but also their impacts outside of the sector. We find that Japan's deflation in the 1990s was characterized by low growth of wage rates, low productivity growth, and a low rate of return on capital. Until 1990, productivity improvements compensated for factor cost pressures on output price, especially the rapid growth of labor cost. In contrast, during the 1990s, decreasing rates of return on capital, not productivity improvements, canceled out the inflationary effect of wage growth. J. Japanese Int.

The Contribution of Sectoral Productivity Differentials to Inflation in Greece

This paper estimates the magnitude of the Balassa-Samuelson effect for Greece. We calculate the effect directly, using sectoral national accounts data, which permits estimation of total factor productivity (TFP) growth in the tradeables and nontradeables sectors. Our results suggest that it is difficult to produce one estimate of the BS effect. Any particular estimate is contingent on the definition of the tradeables sector and the assumptions made about labour shares. Moreover, there is also evidence that the effect has been declining through time as Greek standards of living have caught up on those in the rest of the world and as the non-tradeables sector within Greece catches up with the tradeables.

Exchange rate exposure of sectoral returns and volatilities: Evidence from Japanese industrial sectors

Most studies of exchange rate exposure of stock returns do not address three relevant aspects simultaneously. They are, namely: sensitivity of stock returns to exchange rate changes; sensitivity of volatility of stock returns to volatility of changes in foreign exchange market; and the correlation between volatilities of stock returns and exchange rate changes. In this paper, we employ a bivariate GJR-GARCH model to examine all such aspects of exchange rate exposure of sectoral indexes in Japanese industries. Based on a sample data of fourteen sectors, we find significant evidence of exposed returns and its asymmetric conditional volatility of exchange rate exposure. In addition, returns in many sectors are correlated with those of exchange rate changes. We also find support for the “averaged-out exposure and asymmetries” argument. Our findings have direct implications for practitioners in formulating investment decisions and currency hedging strategies.     

Réactions du Marché d’Actions aux Chocs sur les Taux d’Intérêt de Court Terme,le Cas d’un Marché Emergent: la Bourse Régionale des Valeurs Mobilières (BRVM)

Abstract: Macroeconomics in general and interest rate policy in particular are believed, from a theoretical point of view, to act on stock market movements. This paper discusses this issue in the case of the West African stock market by studying the Regional Securities Exchange (la Bourse Régionale des Valeurs Mobilières (BRVM)) stock market reactions to interest rates innovations. Our results, based on VAR analysis, show that the BRVM stock market does not react immediately to short‐run interest rates’ innovations. Nevertheless, backed reactions occur in imminent periods: at the earliest in the second period and at the latest in the sixth period according to VAR models used. Long‐term effects of short‐term interest rates’ innovations on stock prices returns depend on models specified, on the kind of interest rate and on data frequency. Thus, the long‐term effect of central bank rent rates’ innovations is relatively more important than the one related to interbank rate's innovations. The previous situation of the market is, however, the main determinant of the change of stock prices. Our results show also that stock prices and short‐run interest rates have a similar reaction to both exchange rate and inflation rate's innovations.     

Stock market rationality and price volatility: Tests using Japanese data

This paper tests the stock market rationality hypothesis, which implies that a stock price is determined as the discounted sum of optimally forecasted future dividends. Mankiw-Romer-Shapiro volatility tests and new volatility tests which do not use the unobservable “ex post rational price” are applied to the data from a stock market in Japan. A Hausman type specification test of the market rationality hypothesis is also developed and applied to the data. The results suggest that we cannot reject the hypothesis that the Japanese stock market is rational. A couple of variance inequalities are violated by the data but the violation does not seem to be significant. J. Japan. Int. Econ., December 1987, 1(4), pp. 441–462.

Heterogeneity in lending and sectoral growth: evidence from German bank-level data

This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

Measuring Green Productivity Growth for China's Manufacturing Sectors: 1991–2000*

Over the past two decades, China has sustained rapid economic growth of 8–10 percent, part of which is attributed to the positive total factor productivity (TFP) growth. However, this extraordinary economic performance has been accompanied by severe environmental pollution and associated health damage. The conventional TFP method is biased in interpreting the progress of technology change because it does not consider non‐marketable residues, such as environmental pollution, and, hence, efficiency improvements in terms of pollution abatement technology and environmentally friendly management are ignored. This bias might direct our attention to less efficient use of environmental friendly abatement technologies or send wrong signals to policy‐makers. To address this issue, the present paper applies a modified welfare‐based green TFP approach, treating environmental damage as non‐desirable (negative) residual output. Therefore, environmental efficiency is taken into account to accurately interpret technological progress from a social welfare point of view. Based on a national time‐series input–output table, historical capital and labor input data for China and sectoral level air pollution emission data from 1991 to 2000, the empirical results suggest that with increasingly stringent environmental regulations, many pollution intensive sectors, such as electricity, primary metal and chemical industries, improved their environmental efficiency in the late 1990s. However, because of the weak environmental regulations in construction and transportation, and in sectors primarily composed of small private or township and village industrial enterprises, firms within these industries contributed to increasing environmental degradation.     

The Ex-Dividend Day Stock Price Behavior: The Case of Portugal

This paper examines the ex-dividend day behavior of stock prices in the Lisbon Stock Market over the period 1990–1998, extending on international evidence and discussing the adequacy of competing theories, considering the Portuguese institutional environment. We find that on the ex-day stock prices fall by less than the dividend, which is in line with the findings of several studies based on US and non-US data. The main contributions of this paper are: (1) the rejection of a tax explanation for the stock price drop, because it is inconsistent with the Portuguese tax regime; (2) considering the very small stock price tick and the fact that dividends are always integer multiples of tick size, the discreteness hypothesis of Bali and Hite (Journal of Financial Economics 47(2):127–159, 1998) is also ruled out as a possible explanation for ex-day price movements. We find no evidence of tax related clientele effects. We propose that ex-day price behavior may be an anomaly, reflecting a less than efficient market with low liquidity levels, price stickiness, and insipid arbitrage trading.

DETERMINANTS OF SECTORAL COMPOSITION IN A SMALL OPEN ECONOMY: THEORETICAL AND QUANTITATIVE INVESTIGATIONS OF THE PHILIPPINES

The Philippine economy since the 1980s has undergone shifts of production, employment, and consumption in the direction of the greater share of nontradable sectors, despite relatively stagnant economic growth. This paper examines sources of the sectoral shifts theoretically and quantitatively based on a dynamic model of a small open economy. The theoretical analysis identifies possible factors affecting the evolution of the sectoral composition: changes in sectoral total factor productivity (TFP), the tariff rate, and the terms of trade. Then, the relative importance of these factors is examined quantitatively by conducting simulations of the model calibrated to the Philippine economy.     

East Asian equity markets,financial crises,and the Japanese currency

The paper studies the interactions between the US and four East Asian equity markets. The focus is on the change in the information structure/flow between these markets triggered by the 1997 Asian financial crisis. It is shown that the information structure during the crisis period is different from that in the non-crisis periods. While the US market leads the four East Asian markets before, during, and after the crisis, it is Granger-caused by these markets during the financial crisis period but not in the post-crisis sample. Further, in accordance with concerns reported in the market, the Japanese currency is found to affect these equity markets during the crisis period. The Japanese yen effect, however, disappears in the post-crisis sample. The Japanese currency effect is quite robust as it is found from both local currency and US dollar return data and in the presence of Japanese stock returns. J. Japanese Int. Economies 21 (1) (2007) 138–152.     

Estimating sectoral product quality under quality heterogeneity

This paper estimates product quality at the sectoral level using data from a panel of twelve manufacturing sectors in nineteen OECD countries during the years 1995–2006. The author first derives a gravity model from a firm-heterogeneity model of trade, then measures product quality as the residual of the gravity model. In estimating the gravity model, the author employs the two-step procedure of Helpman et al. (Q J Econ 123(2):441–487, 2008) to correct for biases caused by selection in trade and firm heterogeneity. When aggregated into the country level, the used overall quality metrics do not systematically differ from Hallak and Schott’s (Q J Econ 126(1):417–474, 2011). In line with existing literature, sectoral quality estimates are found positively correlated with sectoral unit prices as well as countries’ income per capita. And the quality gap between rich and poor countries is more pronounced in capital- and skill-intensive sectors. In addition, the autor finds beta- and sigma-convergence in sectoral product quality across countries.     

Total Factor Productivity of the Japanese Rice Industry

We calculate partial factor productivity and total factor productivity (TFP) indices for rice production using panel data across 42 Japanese prefectures from 1996 to 2006, and perform panel unit root tests of TFP convergence across prefectures. We find that during this period, the partial factor productivity growth rates for capital, land and materials stagnated at the aggregate national level, as did the TFP growth rate, despite a large increase in labor productivity. We also identify evidence of a convergence in TFP across Japanese prefectures.     

Discussion of “Aggregate Margin Debt and the Divergence of Price from Accounting Fundamentals”

Burger and Curtis (2017) is an empirical investigation of whether aggregate margin debt correlates with aggregate stock prices and aggregate accounting‐based fundamentals. While the paper convincingly documents a significant relation: aggregate margin debt is higher when aggregate fundamentals‐to‐price ratios are low, it fails to document why. The documented relation could exist because margin traders are the overly exuberant noise traders that push stock prices higher away from fundamental values; or the documented relation could be spurious, and exist because aggregate margin debt rises with aggregate price levels simply because margin loan capacity increases as aggregate price levels increase. With insufficiently granular data (aggregate margin debt measured monthly), the authors are not able to sort out why the relation exists. Thus, interpretation of the findings documented in this paper is difficult.     

Euro-Area Inflation: does the Balassa–Samuelson effect matter?

The paper argues that the Balassa–Samuelson effect is of little importance for the inflation target of the ECB. First, econometric tests of the Balassa–Samuelson effect suggest that the most robust link is found between relative sectoral deflators and relative unit labour costs; i.e. a link that accounts for an incomplete wage pass-through. For the (change in the) HICP — the target of the ECB — and its components additional factors seem to cause divergent international and sectoral developments. Second, countries with high productivity growth in industry may experience a real devaluation in the sector of tradable goods which counters the real appreciation resulting from a relative increase in service prices. It follows that the difference in productivity growth and thus the difference in the size of the relative price adjustment between countries does not have unambiguous consequences for the overall inflation rate, and as such can thus not justify an inflation target well above zero.

How Japanese firms can weather endaka periods: Evidence from the transportation equipment industry

Japan has experienced several appreciation episodes. These appreciations may squeeze profit margins and lower export volumes. This paper investigates whether firms can weather appreciation periods by producing differentiated rather than commoditized products. To do this it investigates different sectors within the Japanese transportation equipment industry. Results from estimating pricing-to-market (PTM) coefficients indicate that firms producing differentiated products can pass-through more of exchange rate appreciations into higher foreign currency prices and thus better preserve their profit margins. Results from estimating trade elasticities are consistent with the PTM results and indicate that the automobile industry has exported much less than predicted after the yen depreciated in 2012. Finally, estimates of the stock market exposure across sectors indicates that the profitability of firms producing differentiated products is less exposed to appreciations. Producing differentiated, knowledge-intensive goods can thus help firms to survive endaka periods.     

Information technology and the Japanese economy

In this paper we compare sources of economic growth in Japan and the United States from 1975 through 2003, focusing on the role of information technology (IT). We have adjusted Japanese data to conform to US definitions in order to provide a rigorous comparison between the two economies. The adjusted data show that the share of the Japanese gross domestic product devoted to investment in computers, telecommunications equipment, and software rose sharply after 1995. The contribution of total factor productivity growth from the IT sector in Japan also increased, while the contributions of labor input and productivity growth from the non-IT sector lagged far behind the United States. Our projection of potential economic growth in Japan from for the next decade is substantially below that in the United States, mainly due to slower growth of labor input. Our projections of labor productivity growth in the two economies are much more similar. J. Japanese Int. Economies 19 (4) (2005) 460–481.     

CEO compensation and firm performance in Japan: Evidence from new panel data on individual CEO pay

Prior studies on Japanese executive compensation have been constrained by the lack of longitudinal data on individual CEO pay. Using unique 10-year panel data on individual CEO's salary and bonus of Japanese firms from 1986 to 1995, we present the first estimates on pay-performance relations for Japanese CEO compensation. Specifically we find consistently that Japanese CEO's cash compensation is sensitive to firm performance (especially accounting measures), and that the “semi-elasticity” of CEO's cash compensation with respect to ROA is 1.3 to 1.4, which is in general agreement with prior estimates elsewhere. As such, our estimates do not support that Japanese corporate governance is unusually defunct with regard to the significance and size of the sensitivity of CEO compensation to accounting profitability. On the other hand, to be consistent with the literature on Japanese corporate governance that tends to downplay the role of shareholders and stress the role of banks and employees, we find that stock market performance tends to play a less important role in the determination of Japanese CEO compensation. Finally, we find that the bonus system makes CEO compensation more responsive to firm performance in Japan. The finding is in contrast to the literature on compensation for regular employees in Japan which often argues that bonus is a disguised base wage. J. Japanese Int. Economies 20 (1) (2006) 1–19.     

The British ‘failure’ that never was? The Anglo‐American ‘productivity gap’ in large‐scale interwar retailing—evidence from the department store sector1

Interwar British retailing has been characterized as having lower productivity, less developed managerial hierarchies and methods, and weaker scale economies than its US counterpart. This article examines comparative productivity for one major segment of large‐scale retailing in both countries—the department store sector. Drawing on exceptionally detailed contemporary survey data, we show that British department stores in fact achieved superior performance in terms of operating costs, margins, profits, and stock‐turn. While smaller British stores had lower labour productivity than US stores of equivalent size, TFP was generally higher for British stores, which also enjoyed stronger scale economies. We also examine the reasons behind Britain's surprisingly strong relative performance, using surviving original returns from the British surveys. Contrary to arguments that British retailers faced major barriers to the development of large‐scale enterprises, that could reap economies of scale and scope and invest in machinery and marketing to support the growth of their primary sales functions, we find that British department stores enthusiastically embraced the retail ‘managerial revolution’—and reaped substantial benefits from this investment.     

R&D and market value of Japanese firms in the 1990s

There is a concern in Japan that the R&D profitability of its domestic firms fell significantly in the 1990s, following the US pattern in the 1980s. This paper finds, however, that the effect of R&D on the market value of a firm, relative to that of tangible assets, increased in the 1990s in terms of both within firm variations and cross section variations, even though the average market value itself significantly fell. More trade and higher foreign ownership significantly enhanced the market value of a firm, and so did more patents in sectors such as pharmaceuticals. J. Japanese Int.

Price formation and the inflationary process in a small open economy (The Netherlands)

Summary Price formation in the manufacturing, services, building and agricultural sectors is analysed by estimating price equations in which unit labour costs, import prices, capacity utilization and the structure of the sellers market (sheltered or competitive) play a part. These equations have been included in a model in which sectoral wages and social security premiums are endogenous as well. This model, which is still partial since it considerse.g. labour productivity and capacity utilization as exogenous, allows a study of the intersectoral multiplier effects which were found to be quite considerable.A large number of simulation results are presented showing the effects of both domestic and foreign exogenous shocks.Finally, an analysis of the relative importance of the factors determining the rise in consumer prices during 1954–1972 has been carried out.
