As demonstrated in several recent studies, data envelopment analysis (DEA) is a useful tool for evaluating and comparing the performance of nations competing in the Olympic Games. Assurance regions (ARs) have been used to further refine the DEA results. These AR DEA models assume that ARs apply...

Data envelopment analysis (DEA) has been proven as an excellent data-oriented performance evaluation method when multiple inputs and outputs are present in a set of peer decision-making units (DMUs). In the DEA literature, a context-dependent DEA is developed to provide finer evaluation results...

This paper investigates the effect of an anticipated fiscal policy on consumption in Japan. I identify an anticipated increment in public investment by using the excess stock returns on the construction industry and by applying the sign restriction VAR. The result shows that GDP and consumption...

We propose effective steps for skill up in five-why for investigate root cause in order to find solutions to quality problems that lead to customer complaints. Skill up in five-why consists of four stages: skill up for beginners, skill up for masters, certification of skill up and evaluation of...

The Japanese government has amassed a huge amount of gross public debts over the past several decades. However, previous empirical works dealing with vector auto-regression (VAR) have not considered the effect of debt on fiscal policy and the macro economy. In this paper, we incorporate debt...

This paper investigates the sources of Japanese business fluctuations since the 1990s taking into account both external shocks (e.g., risk premium and foreign demand shock) and domestic supply and demand shocks. We use the sign-restricted VAR model based on the theoretical model to identify...

This paper empirically investigates the changing dynamics of fiscal policy shocks to the macroeconomy in Japan. By estimating a Markov-switching vector-autoregressive (VAR) model, regime switches in both automatic fiscal responses to output and discretionary fiscal shocks are investigated. The...
