Information based trade,the PIN variable,and portfolio style differences: Evidence from Tokyo stock exchange firms

We investigate whether the variables related to information based trade proposed by Easley et al. [Easley, D., Kiefer, N.M., O'Hara, M., Paperman, J.B., 1996. Liquidity, information, and infrequently traded stocks. Journal of Finance 51, 1405–1436.] help explain the daily price discovery process in an electronically order-driven market of the Tokyo Stock Exchange using the microstructure tick data. We find strong evidence that the value firms show higher probability of bad news occurrences than the growth firms. We also find that the PIN is higher for smaller firms as is the case in the U.S. With the portfolio ranking tests and the Fama and MacBeth test we find that the alpha variable, which represents the information event occurrence rate, is systematically related to required returns, while the evidence related to the PIN is weaker. In the final Fama and MacBeth test, in which the PIN or alpha variable is used as an additional explanatory variable to the benchmark Fama and French three factor model, we find that the sign of the alpha variable supports our hypothesis that the arrival of new information reduces the risk of the stock, though not significantly. We also find that the higher PIN value increases the risk of the stock, at the same time it can marginally improve the explanatory power of the multifactor model. We conclude that the PIN variable cannot be a substitutable proxy variable for the book-to-market factor unlike in the U.S., and that it is strongly related to the size variable.     

INSTITUTIONAL REFORM IN INDONESIA'S FOOD SECURITY SECTOR: THE TRANSFORMATION OF BULOG INTO A PUBLIC CORPORATION

The National Food Logistics Agency (BULOG) which had managed food security, buffer‐stock operations, and domestic food price stabilization through its monopoly over imports and distribution was reorganized into a public corporation, “Perum BULOG”, in May 2003. This study investigates the background and the process of reforming BULOG, and seeks to clarify the characteristics and remaining problems of institutional reform implemented in Indonesia since the economic crisis and the impact of globalization. The major findings are: (1) the reforms led by the IMF and World Bank were an attempt to curtail the rent‐creation mechanism in BULOG and to improve its corporate governance; (2) globalized and standardized modules of institutional reform methods were applied for reforming BULOG, but the implanted institutions will need substantial time to take root; (3) there is still a failure to coordinate among food security institutions, particularly between the Ministry of Agriculture and Perum BULOG.     

Environmental Management in Japan: Applications of Input–Output Analysis to the Emission of Global Warming Gases

Environmental management requires, among other things, the incorporation of environmentally friendly technologies into production processes of environmentally friendly technologies into production processes at the producer level and the adoption of energy consumption patterns which save energy use at the household level. The systemwide approach involving both technology choice and consumer preference seems particularly essential for controlling the total emission of global warming gases. CO₂ and other global warming gases, as well as certain pollution causing gases, are produced when fossil fuels are burnt; and the consumption of fossil fuels occurs in both the production and consumption of goods and services. In this paper we discuss how input–output analysis can be used to estimate the entire production and consumption of global warming gases conditional on production technology and consumer preferences. We also present estimation results and their application to some environmental management issues in Japan. © 1997 John Wiley & Sons, Ltd.     

Lesser evil? Public opinion on regulating fake news in Japan,South Korea,and Thailand – A three-country comparison

This study quantitatively examines and compares public opinion on regulating fake news, and factors affecting the opinion in three Asian countries: Japan, South Korea, and Thailand. Based on the third-person effect, it is hypothesised that the perceived harm of fake news on society increases people's support for fake news regulation. In parallel, according to the lesser evil principle, it is also anticipated that people will be less supportive of regulating fake news if they are aware that there are other non-regulatory counter fake news solutions such as fact-checking. Using original survey data collected from the three countries (n = 5218) and multi-group SEM, it is found that while the first hypothesis holds for all three countries, the second one holds only for Japan and South Korea (the two mature democracies), but not for Thailand (the semi-democratic country). This finding implies that the lesser evil principle also applies in Asian countries, but only in mature democracies where freedom of speech is protected.     

Information Asymmetry and Quarterly Disclosure Decisions by Firms: Evidence From the Tokyo Stock Exchange

This study investigates whether the new quarterly disclosure reporting requirement issued by the Tokyo Stock Exchange was related to the reduction of the degree of private information‐based trade and the liquidity of listed stocks in Japan, or as a reverse causality, helped dichotomize good firms and bad firms as a separating signaling equilibrium. We use the probability of asymmetric information‐based trade (Adjusted PIN) as a measure of information asymmetry and the probability of symmetric order‐flow shock (PSOS) as a measure of market illiquidity. We use a sample of public firms from 2002 to 2007 that chose to either disclose or not disclose quarterly financial reports. We find that the disclosing firms had lower information asymmetry (Adjusted PIN), lower symmetric order‐flow shocks (PSOS), and lower private information‐based trade (PIN). When we conduct further difference‐in‐differences tests, we find that the firms with lower information asymmetry and higher liquidity had a higher tendency to disclose their financial statements and vice versa. Thus, the new disclosure requirement did not necessarily improve the information asymmetry and liquidity of firms, but instead helped good and bad firms form a case for a separating signaling equilibrium.     

Dynamic Analysis of Imitation and Technology Gap

This paper investigates how imitation activities affect the technology gap between developing and developed countries using a North-South model in which the variety of goods is expanding over time. If imitation productivity is high enough, nonrivalrous ideas and inexpensive labor enables developing countries to reduce their technological backwardness by imitating products even if their initial level of technology is far behind the technology in developed countries. We also show that the rise of imitation productivity may benefit both developing and developed countries if they prefer a sufficient variety of goods.     

Topic tones of analyst reports and stock returns: A deep learning approach

We present a novel approach that analyzes topics and tones of analyst reports using a deep neural network in a supervised learning approach. By letting trained classifiers evaluate topics and tones of the reports, we find that incorporation of topic tones significantly enhances the accuracy of predicting cumulative abnormal returns, increasing adjusted ${\mathrm{R}}^2$ from 6.1% without considering textual information to 17.9% with detailed topic tones. This improvement is primarily driven by the inclusion of opinion and corporate fact type of topics. Our findings highlight importance of topic assessment to make the most use of analyst reports for informed investment decisions.
