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.     

Impact of training on the intensification of rice farming: evidence from rainfed areas in Tanzania

Agricultural development is indispensable for poverty reduction and food security in sub‐Saharan Africa (SSA). This study investigates the impact of rice production training in a modified version of the System of Rice Intensification (SRI) on the performance of small‐scale rice farmers in a rainfed area of Tanzania. Utilizing the plot level variation, we employ propensity score matching (PSM) to assess the impact of training on technology adoption, productivity, and profitability. We also estimate a difference‐in‐differences model with plot fixed effects using recall panel data covering the periods before and after training. We found that trainees achieved an average paddy yield of 4.7 tons per hectare and rice profit of 191.5 USD per hectare on the plots where new technologies were adopted, which is higher by about 1.3–1.8 tons and 119–137 USD per hectare than on the other plots. Our study suggests the high potential of transforming favorable rainfed rice growing areas in SSA so as to achieve a rice Green Revolution through training in modern input use and improved agronomic practices.     

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.     

The Effects of Uncertain Divestiture as Regulatory Threat

It has been argued that the threat of regulatory intervention affects firm behavior. We investigate the pricing decision of the dominant firm under regulatory threat, considering the probability of intervention as a function of the price. Our focus is on the case where the potential divestiture of the firm serves as a threat of regulatory intervention. It is shown that under certain conditions associated with the marginal expected penalty, the mere threat of divesting a certain portion of the firm’s manufacturing plants leads to a lower price than the actual divestiture of that same portion. Numerical examples illustrate that with relatively small-scale divestiture, the firm’s price under the threat may be lower than that under the actual divestiture, within a relatively broad range of regulator’s attitudes toward intervention.     

Does Aid for Roads Attract Foreign or Domestic Firms? Evidence from Cambodia

Less developed countries have received substantial foreign aid for transport infrastructure, making its quantitative assessment important. To investigate the effect of aid for road infrastructure on the location of foreign and domestic firms, this study employs the first comprehensive census on all business establishments in Cambodia for 2011 and measures the geographical distribution of aid disbursements in roads. Estimating a negative binomial model, we find that aid disbursements in roads have little influence on the entry of foreign and domestic firms across communes. Compared with the aid effect, the location of firms is more strongly influenced by other determinants such as population size, electricity access, and labor supply.     

Applications of Gram–Charlier expansion and bond moments for pricing of interest rates and credit risk

The purpose of this paper is to demonstrate the powerful and flexible applicability of the Gram–Charlier expansion to pricing of a wide variety of interest rate related products involving interest rate risk and credit risk. In this paper, we develop easily implemented approximations of the prices of several derivatives; swaptions, CMS, CMS options, and vulnerable options. Associated with the default risk, a survival contingent forward measure is constructed.     

On the role of job assignment in a comparison of education systems

Abstract This paper re‐examines how differences in systems for financing education influence GDP by highlighting a neglected function of education policy: it affects the magnitude of gains from job assignment. When more productive jobs demand more skill, privately financed education can increase productivity gains from matching between jobs and skill by increasing the availability of highly educated people. This differs from the standard argument that publicly financed education increases the total amount of human capital by equalizing educational opportunities. It is shown that if job opportunities have large variations in productivity, education policy may face a serious efficiency–equity trade‐off.     

A note on government spending on infrastructure in an endogenous growth model with finite horizon

By extending the work of Mourmouras and Lee (1999), we show that the growth-maximizing income tax rate maximizes also the utilities of not only all current generations but also all future generations. This result means that the statement that the growth-maximizing income tax rate is equivalent to the welfare maximizing one holds true in a stronger sense than Barro (1990) and Mourmouras and Lee (1999) have pointed out.     

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.
