Aged-care support in Japan: perspectives and challenges

This article explores economic aspects of the market for long-term care (LTC) in Japan. As the world's most rapidly aging nation, it is of interest to understand that country's current LTC system and projections of LTC utilization patterns and costs, as well as their potential drivers. Since Japan appears likely to experience important shortfalls in LTC in the future, the authors also discuss alternate forms of provision.     

On estimating Armington elasticities for Japan's meat imports

By fully accounting for the distinct tariff regimes levied on imported meat, we estimate substitution elasticities of Japan's two-stage import aggregation functions for beef, chicken and pork. Although the regression analysis crucially depends on the price that consumers face, the post-tariff price of imported meat depends not only on ad valorem duties but also on tariff rate quotas and gate price system regimes. The effective tariff rate is consequently evaluated by utilising monthly transaction data. To address potential endogeneity problems, we apply exchange rates that we believe to be independent of the demand shocks for imported meat. The panel nature of the data allows us to retrieve the first-stage aggregates via time dummy variables, free of demand shocks, to be used as part of the explanatory variable and as an instrument in the second-stage regression.     

Effectiveness of harvest strategies in achieving multiple management objectives in a multispecies fishery

Fisheries management is characterised by multiple objectives, some of which may be complementary, while others may require trade‐offs between outcomes. Balancing these objectives is made more complex in the case of multispecies and multigear fisheries. In this paper, we develop a bioeconomic model that captures the key elements of such a fishery to test a range of potential harvest strategies to provide insights into how economic target reference points could lead to both desirable and undesirable management outcomes (e.g. discards). The model is developed as a long‐run optimisation model to identify target reference points to achieve multispecies maximum economic yield, and a dynamic recursive optimisation model, which includes more realistic representation of fishers’ behaviour, such as discards and trading of under‐caught species quotas. The potential economic, social and ecological impacts are evaluated using data envelopment analysis (DEA). The results suggest that the use of proxy target reference points can result in short‐term economic benefits at the cost of slower stock recovery and higher discarding. Limiting the number of species subject to quota controls may also prove beneficial in multispecies fisheries, while ensuring quota markets are efficient is likely to produce benefits irrespective of the harvest strategy adopted.     

Public Pension Benefits Claiming Behaviour: new Evidence from the Japanese Study on Ageing and Retirement

The present study explores public pension claiming behaviour among the Japanese elderly. First, we perform financial simulations, estimate expected utility and depict the typical patterns of pension benefits over a lifecycle. We show that a beneficiary's optimal retirement age depends on that beneficiary's mortality risk, discount rate, initial wealth and risk attitude. Second, we use individual‐level data from the Japanese Study on Aging and Retirement (JSTAR) to empirically examine the determinants of claim timing. We find evidence that most of the factors examined in the simulation are, indeed, significantly associated with early claiming among wage earners of pension benefits.     

Total‐Factor Energy and Emission Efficiencies of ASEAN and Other Asian Economies

This research uses the slack‐based measure data envelopment analysis to compute the energy and emission efficiencies of Association of Southeast Asian Nations (ASEAN) and other Asian economies during the 2001–2017 period, employs the Malmquist productivity index to check for the main source of efficiency score changes due to technical changes, and then applies panel Tobit regressions to determine the factors explaining the efficiencies. Our empirical results show that the energy efficiency scores of ASEAN economies had been catching up to other Asian economies after the Global Financial Crisis, whereas the emission efficiency scores of various ASEAN economies had been falling behind other Asian economies over the same period. The main source of efficiency score changes over time is efficiency changes and not technical changes. Decreases in the fossil fuel ratio of net electricity generation and the secondary industry ratio within total industry improve both lead to improvements in energy and emission efficiencies.     

Class Struggle or Embedded Markets? Marx,Polanyi and the Meanings and Possibilities of Social Transformation

Marx and Polanyi both held that socialism, in one form or another, was a preferable and possible alternative to capitalism. Their ideas are seen to offer theoretical tools to understand the tensions and contradictions of capitalism, and to inform ways to overcome them. This paper discusses Polanyi's work from a Marxist perspective in order to illuminate his strengths and weaknesses. Its main focus is to discuss Polanyi's juxtaposing of commodification against exploitation, in diagnosing the problems of capitalist expansion. We suggest that by juxtaposing these two moments, Polanyi not only misses out on a crucial arena of capitalist activity (exploitation), but also undermines his own explication of processes of commodification. This has deleterious consequences for his understanding of the prevalence of poverty under capitalism. It also means that his vision of social transformation and of socialism is profoundly different, and potentially antithetical, to that of Marx. We suggest that for Polanyi's conception of de-commodification to gain greater traction it needs to be combined with Marx's analysis of exploitation and class struggle.     

Male and Female Happiness in Japan During the 2000s: Trends During Era of Promotion of Active Participation by Women in Society

Female happiness has been paradoxically declining over recent decades in reverse proportion to expanding opportunities for women in developed countries, but this subject has not been explored in Japan. Using JGSS, we found that Japanese women have been slightly happier in both absolute and relative terms to men in the 2000s. While happiness of men aged 35–49 and 65 and over temporarily declined in the first half of the decade, women in age groups 20–34 and 65 and over gained happiness in the second half. Moreover, trends in life satisfaction in terms of economic aspects are similar for men and women, slightly advantageous to men in marriage, and largely advantageous to women in non‐market and non‐family aspects.     

Behaviour theory and soft transport policy measures

The aim is to propose a theoretical grounding of soft transport policy measures that aim at promoting voluntary reduction of car use. A general conceptual framework is first presented to clarify how hard and soft transport policy measures impact on car-use reduction. Two different behavioural theories that have been used to account for car use and car-use reduction are then integrated in a self-regulation theory that identifies four stages of the process of voluntarily changing car use: setting a car-use reduction goal, forming a plan for achieving the goal, initiating and executing the plan, and evaluating the outcome of the plan execution. A number of techniques are described that facilitate the different stages of the process of voluntary car-use reduction and which should be used in personalized travel planning programs.     

ON THE ENVIRONMENTAL IMPACT OF CONSUMER LIFESTYLES – USING A JAPANESE ENVIRONMENTAL INPUT–OUTPUT TABLE AND THE LINEAR EXPENDITURE SYSTEM DEMAND FUNCTION

In this study, we undertake some hypothetical experiments and predict the environmental effects of some changes in consumer behavior, using the Japanese Input–Output Table and the Family Income and Expenditure Survey for 2000. We estimate the demand function in a linear expenditure system (LES) and attempt to determine how changes in consumer behavior affect the environmental load induced by household consumption, using the ‘willingness to pay’ concept. Furthermore, we define an index to show the eco-efficiency of consumer behavior. Through such a study, we can determine what action is appropriate for a ‘sustainable consumption’ society. If some change of consumer behavior greatly improved utility while increasing the environmental load, then technological progress to reduce the environmental load must be stimulated. However, if other changes in consumer behavior increase the environmental load while not improving utility very much, then such changes should be strongly discouraged.     

Supplier density and at-home care use in Japan: Evidence from a micro-level survey on long-term care receivers

Following the introduction of the long-term care insurance scheme and deregulation of the market for at-home care services, Japan experienced a substantial increase in expenditure on care for the elderly. Using household-level survey data, we empirically examine whether the increase in care expenditure is associated with supplier density springing from the rise in the number of care providers following deregulation. We provide weak evidence that supplier density in the at-home care market is positively correlated with probability to use care or expenditure on care. Moreover, we find no link between the share of for-profit providers and the demand for at-home care services.
