This study investigates the short-term effects of public-sponsored job training (PJT) for the unemployed on their subsequent working status and income using a large-scale Japanese government survey and the propensity score matching technique. We find a significantly positive effect on the probability of working for both men and women; however, the point estimate is larger for women than for men. We also find a gendered difference in the effects on income and probability of being employed as a regular worker, with significantly positive effects for women but no significant effects for men, suggesting that PJT might be more effective for women. We confirm that the results are robust to a range of empirical specifications.

This study applies the difference-in-difference method on panel data collected from internet surveys to investigate changes in the preventive behaviors and mental health of individuals as influenced by the COVID-19 state of emergency declaration between March and June 2020. The key findings are: (1) The declaration led people to exhibit preventive behaviors but also generated negative emotions; (2) Such behaviors persisted even after deregulation of the state of emergency; (3) Making the declaration early (vs. late) had a larger effect on preventive behavior, with the gap between residents’ behaviors for areas that made early vs. late declarations persisting after the deregulation; and (4) The effects on mental health diminished during the state of emergency and disappeared after its deregulation.

This paper examines how new science-intensive drugs improve the longevity of the population and the cure rate of hospitalized patients (inpatients). We develop a comprehensive longitudinal-disease-level panel data set, matched with drugs with a new molecular entity (NME) launched in Japan and classified by science intensity. Estimates suggest that the increase in the diversity of science-intensive NMEs (or NME stock) used for treating a disease significantly contributed to longevity and to the improvement of the cure rate of inpatients. In contrast, we find that non science-intensive NME stock does not significantly enhance these outcomes. Our results also suggest that controlling for the effects of surgeries does not reduce the effects of science-intensive drugs and that quality of science exploited for the discovery of an NME also plays a role in the effects. We have validated our indicator of science-intensive NMEs as a measure of the contribution of drugs to treatment, based on a survey of physicians. The results show that scientific advancement and exploitation for drug innovations critically contribute to improving human welfare.

Welfare gains achieved through international trade are a cornerstone of the literature on international economics. However, the data and research methods needed to empirically assess these welfare gains have only recently become available. Building on recently developed methodologies for estimating the elasticity of substitution and computing welfare gains from trade, we estimate Japan's welfare gains from liberalizing trade in the manufacturing sector. To do so, we estimate the elasticities of substitution using Japanese customs data at Harmonized System (HS) 9-digit product codes. The analysis shows that Japan's welfare gains from trade liberalization occurred especially from the end of the 1990s onward, and reached 16 percent vis-à-vis the autarky situation.

This paper analyzes the Postwar Japanese economy with a parsimonious neoclassical growth model that incorporates the demographic transition in Japan. We find that i) the increase in the aged population share can account for most of the decline in employment and reduced output by 8%, ii) workweek shortening policy led to a 20% reduction in output from its potential level by reducing hours worked over the 1988-1994 period, iii) the rise in labor tax led to an 11% reduction in output from its potential level by discouraging hours worked, iv) the shift in the composition of government spending may have caused a slowdown in productivity growth and hence a reduction in the potential output level itself.

Given that real-world infection-spread scenarios pose many uncertainties, and predictions and simulations may differ from reality, this study explores factors essential for more realistically describing an infection situation. It furnishes three approaches to the argument that human mobility can create an acceleration of the spread of COVID-19 infection and its cyclicality under the simultaneous relationship. First, the study presents a dynamic model comprising the infection–mobility trade-off and mobility demand, where an increase in human mobility can cause infection explosion and where, conversely, an increase in new infections can be made temporary by suppressing mobility. Second, using time-series data for Japan, it presents empirical evidence for a stochastic trend and cycle in new infection cases. Third, it employs macroeconometrics to ascertain the feasibility of our model’s predictions. Accordingly, from March 2020 to May 2021, the sources of COVID-19 infection spread in Japan varied significantly over time, and each change in the trend and cycle of new infection cases explained approximately half the respective variation.

This study examines the low–interest rate environment in Japan from mid-1990 to the end of 2020, using a dynamic Nelson–Siegel framework emphasizing the role of the decay factor. A regime-switching model estimates that the regime with low decay factor and bond yield volatility (“low” regime) has persisted since the early years of Bank of Japan's quantitative and qualitative monetary easing (QQE) policy. A shift away from the low regime can instantly increase the 10-year government bond yield by over 50 basis points by increasing the term premiums with little changes in the expected short rate.

Equity carve-outs and spin-offs generate listed subsidiaries that embrace conflicts of interests between controlling and minority shareholders. We find robust evidence that long-tenure managers tend to conduct these asset divestitures, especially when the divesting firm has a concentrated ownership structure. The result suggests that managers with the opportunity to extract private benefits establish entities that provide such opportunities. Meanwhile, large shareholders prevent managers from conducting these divestitures when they have sufficiently large cash flow rights. We find no evidence that firms launching listed subsidiaries achieve better financial outcomes than asset sell-off firms. Problematic entities in corporate governance further create such entities.

This paper considers the relationship between wealth, financial literacy and several other variables using data from Japan's first large-scale survey on financial literacy. Using an instrumental variables approach to account for possible endogeneity of financial literacy, we find that financial literacy has an economically large and positive impact on wealth accumulation. We also decompose financial literacy into 5 sub-categories and find that deposits literacy, risk literacy and debt literacy have significant impacts on wealth accumulation in Japan, whereas inflation literacy and insurance literacy do not. Several variables suggested by behavioral economics, such as over-confidence, self-control, myopia and risk-aversion are also significant determinants of wealth.

We develop new economic policy uncertainty (EPU) indices for Japan from January 1987 onwards, building on Baker et al. (2016). Each index reflects the frequency of newspaper articles that contain certain terms pertaining to the economy, policy matters, and uncertainty. Our overall EPU index co-varies positively with implied volatilities for Japanese equities, exchange rates, and interest rates and with a survey-based measure of political uncertainty. It rises around contested national elections and major leadership transitions in Japan, during the Asian financial crisis and in reaction to the Lehman Brothers failure, U.S. debt downgrade in 2011, Brexit referendum, the deferral of a consumption tax hike, and the onset of the COVID-19 pandemic. Our uncertainty indices for fiscal, monetary, trade, and exchange rate policy co-vary positively but also display distinct dynamics. For example, our trade policy uncertainty (TPU) index rocketed upwards when the U.S. withdrew from the Trans-Pacific Partnership. VAR models imply that upward EPU innovations foreshadow deteriorations in Japan's macroeconomic performance, as reflected by impulse response functions for investment, employment, and output. Our study adds to evidence that credible policy plans and strong policy frameworks can favorably influence macroeconomic performance by reducing policy uncertainty.
