The advance of web technology has allowed increasingly number of people to have access to Social Network Sites. Different members of society, including people of all ages and social classes, have used Facebook, Twitter and LinkedIn. This study examines the relationship between the use of Social...

We conducted a questionnaire survey in the Kanto area regarding peoplefs dissatisfaction with various aspects of their dwelling environment. Dissatisfaction with access to transportation, shopping and medical facilities are important reasons for moving house. Probit model estimation implies that...

This study constructs a variety expansion growth model with public research spending, in which public researchers raise the productivity of private R&D. We show that the rela- tionship between public research spending and the growth rate follows an inverted U-shape. This is because public...

The effectiveness of nontraditional monetary policy is controversial at least in Japan. Making use of data from the quantitative easing monetary policy period, this paper presents statistical evidence on the effectiveness of nontraditional monetary policy. We empirically demonstrate that...

The paper tackles the issue of possible misspecification in fitting skew normal distributions to empirical data. It is shown, through numerical experiments, that it is easy to choose a distribution which is different from this which actually generated the sample, if the minimum distance...

Empirical tests of purchasing power parity (PPP) are implicitly based on the conditions of symmetry and proportionality of the price coefficients. We investigate a separate condition, which we term homogeneity. Specifically, while there may be factors that drive a wedge between prices and...

We investigate the problem of reordering agents starting from an existing queue. First, we introduce four important axioms of the problem, budget balance (BB), outcome efficiency (OE), strategyproofness (SP), and individual rationality (IR). Unfortunately, it is easy to show that these four...

We investigate the implications of egalitarian equivalence (Pazner and Schmeidler [22]) together with queue efficiency and strategyproofness in the context of queueing problems. We completely characterize the class of mechanisms satisfying the three requirements. Though there is no mechanism in...
