The effects of fishery harbor-based brands on the brand equity of shore fish: An empirical study of branded mackerel in Japan

In Japan, some fishery cooperative associations use their fishery harbor names as a brand to differentiate their own shore fish. Most notable is the branding of mackerel. In this paper, we analyze the effects of branding using a discrete/continuous model. The results are as follows. First, there is first-mover advantage in the branding of mackerel. For instance, unlike other brands of mackerel, Seki-saba as the pioneering brand can increase its brand equity. Second, other brands have opposing effects that increase and decrease the brand equity of the pioneering brand. We find the former is strongest in the early stages of fishery branding when there are few competing brands of mackerel, while the latter becomes stronger in later stages when many other brands emerge.     

Globalization and economic inequality in the short and long run: The case of South Korea 1975–1995

We analyse the determinants of the Gini coefficient for income and expenditure in South Korea between 1975 and 1995. In both cases, we do not find support for the Kuznets inverted-U hypothesis. From an economic globalization viewpoint, the opening of goods markets reduces income inequality in both the short run (the Gini coefficient for income) and the long run (the Gini coefficient for expenditure). On the other hand, the opening of capital markets increases income inequality in both the short and the long run, although the latter is not statistically significant. These results suggest that the effect of economic globalization on income inequality has two routes and two different speeds.     

Divergence or convergence?: Income inequality between cities,towns and villages in Japan

Researchers have emphasized different aspects of income inequality, including the statistical evidence of interregional per capita income convergence (following the economic growth theory) and the increase in individual income inequality. This study clarifies these issues, by analyzing the interregional income inequality of cities, towns and villages data in Japan from 1986 to 1999. The results of this empirical analysis show that the interregional income inequality decreases in the 1990s, in spite of the increase in individual income inequality.     

Differences in travel objectives between first‐time and repeat tourists: An empirical analysis for the Kansai area in Japan

This study investigates the differences in travel objectives between first‐time and repeat tourists. We conduct a questionnaire survey of travel agencies, which asked about specific tour plan for target tourists, their experiences and travel objectives in the Kansai area in Japan. We estimate a logit model for the relationship between travel objectives and visiting experiences. The results indicate that the first‐time tourists' main objective is to enjoy looking around sightseeing spots, while the repeat tourists' objective is simply to enjoy the stay, including the hotel visit and participating in events.

Is There Chaos in The World Economy? A Nonparametric Test Using Consistent Standard Errors*

A positive Lyapunov exponent is one practical definition of chaos. We develop a formal test for chaos in a noisy system based on the consistent standard errors of the nonparametric Lyapunov exponent estimators. For international real output series, the hypothesis of the positive Lyapunov exponent is significantly rejected in many cases. One possible interpretation of this result is that the traditional exogenous models are better able to explain business cycle fluctuations than is the chaotic endogenous approach. However, our results are subject to a number of caveats.     

Menu costs and Markov inflation: A theoretical revision with new evidence

We revisit a foundational theoretical paper in the menu-cost literature, Sheshinski and Weiss [1983. Optimum pricing policy under stochastic inflation. Review of Economic Studies 50(3), 513-529], one of the few to treat stochastic inflation with persistent deviations from trend. In contrast to the original finding, we show that optimal pricing in this environment entails using different (s,S) bands in high-inflation and low-inflation states of the world. The low-inflation band is strictly contained within the high-inflation band. This revised solution has very different implications from the original one. Firms are generally risk loving, not risk averse, with respect to inflation. An increase in the variance of inflation increases price dispersion when inflation is high and decreases price dispersion when inflation is low. On an aggregate level, this optimal pricing would lead to bunching of prices and non-neutrality of money in the setting of Caplin and Spulber [1987. Menu costs and the neutrality of money. Quarterly Journal of Economics 102(4), 703-725]. To test the main finding, we construct an establishment-level dataset from the months surrounding Mexico's “tequila crisis” in 1995. In the high-inflation state, price increases are larger and establishments allow their prices to vary more widely around their respective long-run mean relative prices. Cross-establishment price dispersion is lower, but this result seems due to decreased establishment heterogeneity rather than narrower (s,S) bands. Overall, the evidence suggests that establishments employ wider (s,S) bands in the high-inflation state.     

THE INF‐T TEST FOR A UNIT ROOT AGAINST ASYMMETRIC EXPONENTIAL SMOOTH TRANSITION AUTOREGRESSIVE MODELS

This paper proposes a new test for a unit root against an alternative of asymmetric exponential smooth transition autoregressive models, by extending the infimum test developed by Park and Shintani. Simulation results suggest that the test performs reasonably well in finite samples. The proposed test is also applied to real exchange rates to examine their asymmetric and nonlinear mean‐reverting properties.     

Cost analysis of leuprorelin acetate in Japanese prostate cancer patients: comparison between 6-month and 3-month depot formulations

Aims: This study aimed to evaluate the economic value for leuprorelin acetate 6-month depot compared with leuprorelin acetate 3-month depot from a societal perspective in Japanese prostate cancer patients.

Methods: The cost analysis estimated the reduction in direct and indirect costs as well as intangible costs saved by having one less injection. Claims data were used for the analyses of direct and indirect costs reduction. A discrete choice experiment based on a web-based survey estimated the monetary value of the intangible costs for one injection. Another web-based survey of prostate cancer patients, who had received treatment with leuprorelin acetate injections, was carried out to calibrate the results of the discrete choice experiment.

Results: Reductions in medical costs and loss of productivity for having one less injection in prostate cancer patients receiving leuprorelin acetate were JPY 5,670 and JPY 1,723, respectively. Intangible costs saved by using a 6-month depot formulation instead of a 3-month depot formulation for the injection of leuprorelin acetate were estimated to be JPY 19,872, including the values for a reduction in pain (JPY 3,131), injection site reactions (JPY 11,545), waiting time (JPY 9,479), and subtracting the value of medical consultation (JPY 4,283). The total cost reduction for having one less injection was JPY 27,265.

Limitations: The respondents from the internet panel provided by a survey company are not necessarily a representative population of Japanese society.

Conclusions: Leuprorelin acetate 6-month depot has an advantage in monetary value in the reduction in medical costs, loss of productivity, and intangible costs for having one less injection in prostate cancer patients compared with leuprorelin acetate 3-month depot. In the costs for treating with leuprorelin acetate, the percentage of intangible costs might not be negligible. The intangible costs will probably be actively evaluated to proceed to patient-centered healthcare in society.     

Households’ attitudes toward earthquake protection: An empirical analysis of the impact of fiscal support in Japan

Faced with an aging society and major earthquake risk in the near future, promoting the improvement of existing houses is one of the most important issues in Japan. In this paper, we formulate two types of demand models for home safety: a model for barrier-free conversion and a model for seismic retrofit based on a logit model. We explore statistically the factors that affect the demand for each improvement using prefectural data in Japan. We also analyze statistically the significance and impact of financial support programs for improving existing houses, which the Japanese government has implemented at the prefectural and municipal level. The results clarify the differences between the determinants of each type of improvement and show that the support program for barrier-free conversion has a positive and statistically significant effect on households’ preference. However, neither the seismic test nor the seismic retrofit program conducted by prefectures has a positive impact on preference, whereas those by municipalities do affect preference.
