Japan's national innovation system: current status and problems

This paper examines Japan's national innovation system thatwas so successful in the 1980s and seems to have lost its competitivenessin the 1990s. In recent years, the competitiveness of industryrelies not only on industry itself but more and more on thenational innovation system as a whole. The first section ofthe paper points out that Japan's potential economic growthrate is likely to decline in the twenty-first century, primarilybecause of the rapidly ageing population, and, therefore, itis important to increase productivity through technologicalprogress. Then, in the following sections, each sector of Japan'snational innovation system, namely industry, universities, andgovernment, is examined and directions of reform are suggested.     

SIMULTANEOUS MEASUREMENT OF TIME AND RISK PREFERENCES: STATED PREFERENCE DISCRETE CHOICE MODELING ANALYSIS DEPENDING ON SMOKING BEHAVIOR*

Measuring time and risk preferences and relating them to economic behaviors are important topics in behavioral economics. We developed a new method to simultaneously measure the rate of time preference and the coefficient of risk aversion. Analyzing the individual‐level relationships between preference parameters and cigarette smoking, we conclude that current smokers are more impatient and risk‐prone than nonsmokers. Heavy smokers are the most impatient and risk‐prone, whereas ex‐smokers are the most patient and risk‐averse. Among nonsmokers, neither age‐related nor gender‐related differences were found. On the other hand, risk and time preferences are significantly different according to age and gender for smokers.     

Pension and child care policies with endogenous fertility

This paper presents an examination of effects of a child allowance on fertility under a pay-as-you-go pension system. In these analyses, the child allowance is financed by taxation of two kinds: an income tax and a consumption tax. Comparative static analyses show that a child allowance financed by income tax revenues can always raise fertility. Similarly with income tax, a child allowance financed by consumption tax can always raise fertility. Furthermore, our paper presents examination of optimal child allowance and transfer for older people.     

Hepatocellular carcinoma with tumor thrombus in the inferior vena cava and right atrium

Tumor thrombus (TT) in the inferior vena cava (IVC) and right atrium (RA) is rarely encountered. We have diagnosed before death and treated a case of hepatocellular carcinoma (HCC) with TT in the IVC and RA, accompanied by a brain metastasis. The image characteristics on computed tomography (CT), magnetic resonance imaging (MRI), and conventional angiography are discussed.     

International migration,foreign direct investment,and development stage in developing economies

The existing empirical results on the relationship between FDI and migration are rather mixed. This study reevaluates, both theoretically and empirically, how inward FDI relates to emigration in developing countries. Our model illustrates that the relationship between inward FDI and emigration flows depends on the development stage of a developing country, that is, there is a positive association between inward FDI and emigration flows for relatively less‐developed countries but a negative association between these two variables for relatively developed countries. We confirm the empirical validity of our model prediction using the panel data of 21 OECD and 51 non‐OECD countries during the period from 2003 to 2012. Our results argue that as economic development proceeds in a developing country, the home effect of inward FDI associated with intensified labor demand would dominate the linkage effect that induces the brain drain problem through enhancing the socioeconomic ties with migrant networks.     

The Information Content of Corporate Pension Funding Status in Japan

This paper tests if a firm's pension funding ratio (pension assets/PBO) reveals the management's private information about the firm's operation when the firm can exercise discretion in pension funding. The lax enforcement of pension funding rules and the prevalence of management forecasts make Japanese firms an ideal testing ground. We show that, among firms with large business uncertainty, large accruals, or high effective tax rates, the pension funding ratio predicts the firm's management forecast errors significantly beyond conventional control variable and the effects of pension accounting management. However, the stock market does not appear to incorporate this information immediately.     

A tool for scrutinizing bank bailouts based on multi-period peer benchmarking

In the wake of the recent global financial crisis central banks and regulators are concerned about re-direction of bailout funds into dividends. Yet, we do not know much about the extent banks follow dividend policies and funding decisions optimal to generating shareholders' wealth because banks have been mostly absent from an otherwise expansive literature on dividend policy. A relative, multi-period analysis of the troubled Japanese regional banks for the period 1998–2007 identifies inefficiencies in the levels of dividends, retained earnings, external funding and shareholder returns. The study unfolds further by investigating associations between inefficiencies and non-performing loans, followed by a comparison of efficient versus inefficient banks across good and bad economic times. The methodology captures linkages among yearly financial decisions over multiple periods, thus summarizing long-term performance. The new approach can guide continuous benchmarking of bank financial performance, as well as help policy-makers monitoring potential misappropriation of bailout funds during financial crises. The findings indicate a potential to adjust levels of debt and equity funding, and substantial room for improvement in shareholder returns. Associations between non-performing loans and technical inefficiencies are generally statistically significant.     

Willingness to pay for QALY: perspectives and contexts in Japan

Abstract

Objectives: Theoretically, willingness-to-pay (WTP) for quality-adjusted life years (QALY) can vary depending on social and personal preferences and on ex-ante and ex-post settings. However, empirical investigations into the theoretical differences are lacking. In Japan, setting the threshold has been controversial since a pilot project to implement health technology assessments (HTA) launched in 2016. The study aim is to estimate WTP values for one additional QALY from different perspectives, health statuses, and contexts to confirm the difficulty in setting a uniform price threshold using WTP.

Methods: More than 1,000 respondents representing a cross-section of the Japanese population answered each of nine questionnaire decks in an online panel. WTP values were estimated on three different perspectives (personal, social, and socially inclusive) and on two contexts (ex-ante and ex-post). This study primarily used the non-parametric spike model based on double-bounded dichotomous choice (DBDC) settings to obtain the conditional WTP values.

Results: WTP per QALY was higher in the severe health status than in the moderate health status from all perspectives. Respondents from the socially inclusive perspective estimated the highest WTP value for a new drug. Respondents were also asked about life-threatening diseases in ex-post and ex-ante. The WTP value in ex-ante was higher than in ex-post, and demographic factors affecting the WTP were different in both situations. The various WTP values were obtained from these surveys.

Limitations: The analysis was based on data collected from an internet panel, which could be biased. There is also a risk that respondents answered the questionnaire differently if asked in everyday situations.

Conclusion: Use of a uniform price threshold may not be appropriate in policy settings, because it may not reflect diverse preferences based on different situations, such as disease type and severity. Setting a price threshold as Japan institutes an HTA system requires further research.     

Measurement of Dynamic Efficiency in Production: An Application of Data Envelopment Analysis to Japanese Electric Utilities

The purpose of this paper is to measure productive efficiencies when a firm employs quasi-fixed inputs that cannot be instantaneously adjusted to their optimal levels. To this end, data envelopment analysis (DEA) is extended to a dynamic framework so that investment behavior can be modelled with the efficient production frontier. Based on the work of Nemoto and Goto (1999), we show how the efficiencies of quasi-fixed inputs and their adjustment processes are evaluated. An application to Japanese electric utilities over the 1981–1995 period delivers empirically plausible results and proves the usefulness of the procedure.
