Empirical Analysis of Firm-Dynamics on Japanese Interfirm Trade Network

This paper uses data of international iron ore trade in 2009, which cover 61 countries and 134 trade relationships, to evaluate the bargaining power of both export and import countries from the perspective of social network. The countries’ positions in the iron ore trade network and their bargaining power are examined through analysis of their Freeman degree centralities, Bonacich powers, betweenness centralities, and flow centralities. The results of these analyses identify prominent exporters, importers and brokers with great bargaining power, and countries with potential to improve their bargaining positions. The results also reveal the reason why the international negotiations of iron ore trade were almost always in favor of exporters.

Abstract. In this article, the authors provide an empirical analysis of the obtrusiveness of and participants' compliance with a relatively new psychological ambulatory assessment method, called the electronically activated recorder or EAR. The EAR is a modified portable audio-recorder that periodically records snippets of ambient sounds from participants' daily environments. In tracking moment-to-moment ambient sounds, the EAR yields an acoustic log of a person's day as it unfolds. As a naturalistic observation sampling method, it provides an observer's account of daily life and is optimized for the assessment of audible aspects of participants' naturally-occurring social behaviors and interactions. Measures of self-reported and behaviorally-assessed EAR obtrusiveness and compliance were analyzed in two samples. After an initial 2-h period of relative obtrusiveness, participants habituated to wearing the EAR and perceived it as fairly unobtrusive both in a short-term (2 days, N = 96) and a longer-term (10-11 days, N = 11) monitoring. Compliance with the method was high both during the short-term and longer-term monitoring. Somewhat reduced compliance was identified over the weekend; this effect appears to be specific to student populations. Important privacy and data confidentiality considerations around the EAR method are discussed.
