Urbanizing economics

Action takes place at a given time and place. As a science of human action, economics is, therefore, just as much about the spaces where real action occurs as it is about real time. The implications of real time for social order is better recognized than the significance of “action space.” The living city is the principal locus of action space and enabler of social change as well as the source of fundamental concepts in economic theory. Just as a loss of density and diversity in cities tends to retard dynamic discovery and development, the turn in economic theory in the mid-20th century toward static equilibrium reflected a move from an urban-based to a plantation-based conception of the economy—from the city to the farm. Some recent developments in network theory, game theory, and geography, however, can be interpreted as a re-urbanization of economics.

An Approximation Scheme for Diffusion Processes Based on an Antisymmetric Calculus over Wiener Space

In this paper, we show that every antisymmetric multiple stochastic (Ito’s) integral has a polynomial form of single and double ones. As an application, a new approximating scheme for the solution to a stochastic differential equation is proposed.     

The nature and limits of Gary Becker’s theory of racial discrimination

To what extent does Gary Becker’s model of discrimination capture “the essence of prejudice and discrimination”? After providing a general outline of Becker’s original model and summarizing some subsequent developments, this paper takes a critical perspective on the model to suggest that the absence of imperfect information in his approach unhelpfully limits its explanatory power. Instead, an approach that allows for the possibility of genuine error and draws on Adam Smith’s analysis of the impact of markets on one’s moral sense offers a deeper, more realistic understanding of what it means for people to express their prejudice (or not) through their choices.     

Decreasing marginal impatience in a two-country world economy

By using a two-country model with endogenous time preference, this paper examines the dynamic implication of decreasing marginal impatience (DMI). To ensure stability, we assume that one country has DMI whereas the other has increasing marginal impatience (IMI). The resultant equilibrium dynamics differ from what can be inferred from the analysis of the standard IMI model (e.g., Devereux and Shi in J Int Econ 30:1–25, 1991). An increase in fiscal spending, in either country with DMI or IMI, has always contrasting long-run effects on domestic and foreign consumption and hence on domestic and foreign welfare; and the same policy definitely raises the interest rate in the long run.     

A Model of a Price-setting Duopoly with a Wage-rise Contract

This paper considers a wage-rise contract between a firm and its employees as the firm's strategy, and suggests a wage-rise-contract policy. The policy is a promise by the firm that it will announce a certain output level and a wage premium rate, and if it actually produces more than the announced output level, then it will pay each employee a wage premium uniformly. First, this paper examines the case in which one of two firms unilaterally offers the wage-rise-contract policy by using a two-stage price-setting duopoly model. It is then shown that there exists an equilibrium which coincides with the Stackelberg solution where the firm adopting the policy is the leader. Next, this paper examines the case in which both firms can offer the wage-rise-contract policy in the model. It is then shown that there exists an equilibrium which is more profitable for both firms than in the unilateral case.     

International airports: financing methods in Japan

Capacity shortages at international airports in Japan are the most serious impediment to liberalization and free competition in international aviation. Here, we deal with the causes of this shortage, Japanese institutional systems of airport improvement and new financing methods for international airport capacity expansion in metropolitan areas. We emphasize the effectiveness of the joint-stock corporation system as a financial device. The introduction of the joint-stock corporation is one kind of airport privatization, but its characteristics completely differ from those of privatized airports in some European countries and in New Zealand.     

Attributes of Foreign Subsidiaries and the Location Strategy of Multinational Firms in Global Cities in Latin America

International business research has recently honed in on the subnational dimension of multinational enterprises (MNEs), particularly the city level. Through a binomial logistic regression of data from 254 foreign subsidiaries of 10 Latin American global cities between 2006 and 2012, we found that specific attributes of the firm related to the industrial sector, subsidiary control, and ownership level have a positive effect on the location choice in cities. In addition, we found that in the previous period and during the international financial crisis, MNEs exploited their internalization advantages more intensely by exerting greater control over their subsidiaries in global cities.     

Factors determining residents’ preparedness for floods in modern megalopolises: the case of the Tokai flood disaster in Japan

This study examines how flood risk perception and home ownership affect residents’ preparedness for floods, focusing specifically on the case of the Tokai flood disaster in Nagoya City, one of Japan’s biggest metropolises, in 2000. The greatest rainfall ever recorded in Nagoya City (566.5 mm) occurred on 11–12 September 2000; as a result, a local river burst its banks and flooded the city. A survey was conducted of residents of the affected area in Nagoya City and its adjacent region. The respondents were asked to rate the extent of their experience with, anticipation of, and preparedness for floods before and after the Tokai disaster in terms of taking special measures against floods. The results showed that the degree of preparedness for floods was determined by the level of fear of floods and the amount of damage sustained during the Tokai flood, especially for homeowners. However, the residents’ preparedness did not depend on their anticipation of floods. These findings show that preparedness for floods depends on ownership of a home, fear of flooding, and the amount of damage from previous floods rather than on previous experience with and anticipation of floods.     

Self‐Assessed Social Position and Poverty

In this article, we use microlevel data extracted from the 2006 Japanese General Social Surveys to analyze the relationships between self‐assessed social position and socioeconomic factors such as income and poverty. We provide the posterior results of the estimation of the Bayesian multivariate ordered probit model and propose an inequality measure for self‐assessed social position on the basis of the posterior results. We call the inequality measure “regret” and show that the distributions of regret differ for people above and below the poverty line.     

The Structure of the Japanese Stock Market

The Japanese stock market is characterized by two prominent features. First, stock prices have been extremely volatile over the past ten years. Second, the market is dominated by cross-shareholdings and stagnant individual stock ownership. So, there are two purposes on this paper. The first is to assess the effects of stock cross-holdings on the stock market. The second is to look at recent stock price fluctuations, in the bubble period before 1990 and during the subsequent collapse. It will be recognized that these two features are interrelated.
