The field of artificial intelligence (AI) is experiencing a period of intense progress due to the consolidation of several key technological enablers. AI is already deployed widely and has a high impact on work and daily life activities. The continuation of this process will likely contribute to...

This paper develops a new way to present standard urban models graphically and a new rent function called the rent-commuting cost function. The rent-commuting cost function represents the relationship between rent and total commuting cost. At least theoretically, it is superior to the...

This paper performs a comparative static analysis to derive the effect of a change in the wages of the rich living in the suburban area of a city on the welfare of the poor living in the central area of the city. It assumes that commuting cost is a function of distance and wages. A sufficient...

This paper develops a new way to present standard urban models graphically and a new rent function called the rent-commuting cost function. The rent-commuting cost function represents the relationship between rent and total commuting cost. At least theoretically, it is superior to the...

The author derives the probability that price discrimination improves social welfare, using a simple model of third-degree price discrimination assuming two independent linear demands. The probability that price discrimination raises social welfare increases as the preferences or incomes of...

This paper argues that "Do auctions raise consumer prices?" is a misleading question. License fee payment methods, rather than spectrum assignment methods, are key factors that bring forth different market outcomes in the wireless telecommunication industry. This paper analyzes and discusses the...

This paper proposes a new estimation method of total cost and average cost curves and applies it to the telecommunications industry. The method is more flexible and entails less hassle for data collection than traditional methods. The results show that the long-run average cost (LRAC) curve is...

Considering that privacy concerns could affect users' privacy behavior as an antecedent, it is important to investigate the impact of strengthened personal data protection regulation on users' privacy concerns. However, there exists mixed views that the personal data protection regulation has a...
