本稿では、独立・起業がもたらす金銭的・非金銭的報酬について、全国就業実態パネル調査（JPSED）を用いて検証した。既存研究では、自営業者・起業家の報酬水準は、そのリスクと比較すると相当低いと結論しているものが多い。しかし、自身への報酬だけを金銭的成果とすると過小評価につながり得る。本稿では、筆者が収集した企業経営者に関するデータを用いて、全国就業実態パネル調査から得られた収入額を補正し、独立起業により得られる金銭的報酬への影響を推定した。結果は、起業はプラスの金銭的報酬をもたらす可能性を示しており、少なくともマイナスの結果ではなかった。また、上述の補正を行わずに通常の報酬額を対象とした分析を行った場合でも、少なくともマイナスの効果を持っているとは認められなかった。また、金銭的報酬は 2021 年から有意に高まっていることが示された。非金銭的報酬については、裁量度、エンゲージメント、仕事満足度が有意に上昇することを確かめた。こうした非金銭的報酬の水準も、2020 年度あたりから上昇していた。また独立起業はこどもの数を増やす可能性が示された。その一方で、幸福度、生活満足度には影響を及ぼさないことが示された。

Abstract

Empirically investigating the workings of institutional complementarity in organisations has been a challenge in the social sciences domain for a long time. This paper examines data from the World Management Survey (WMS) using a new machine learning method termed as iterative random forest (iRF), which is used in the field of biostatistics. An empirical study of complementarity was conducted in small and medium-sized enterprises using WMS data. The effects of 18 management quality indicators on profitability, growth and viability were examined using machine learning methods (i.e. random forest [RF] and iRF). The analysis revealed the relative importance of whether high performers are properly rewarded, poor performers are reassigned and retrained and the criteria for high and low performance are well established. Furthermore, the study results revealed that the ability to set short-term goals based on a long-term perspective is complementary to many other indicators. These findings are consistent with the findings of a survey study that examined many empirical studies on the workings of institutional complementarity. This indicates that iRF is a credible and promising method for empirical research on institutional complementarity.

The Great East Japan Earthquake created health hazards for many people. Using Panel Data gathered in Iwanuma city, Japan, at two points in time (in 2010 before the quake, and in 2013 after the quake), we found that the high degree of housing damage negatively affected victims' self rated health (SRH) (direct effect), and decreased the levels of their social connections, which in turn also had a harmful effect on their SRH (indirect effect). We also found that although the direct impacts of earthquakes disappear relatively quickly, the harmful indirect effects associated with a decrease in social connections are slower to dissipate. We conducted a first-difference two-step GMM estimation to consider the possible problem of endogeneity. The results support the above conclusion, and show that in the short-term, the indirect impacts of the earthquake accounted for 55% of all the impacts experienced.
