Management of science, serendipity, and research performance: Evidence from a survey of scientists in Japan and the U.S.

Murayama, Kota: Makoto Nirei: Hiroshi Shimizu
『Research Policy』 Vol.44 No.4 pp.862-873 （2015/05/01）

In science, research teams are increasing in size, which suggests that science is becoming more organisational. This paper aims to empirically investigate the effects of the division of labour in management and science on serendipity, which has been considered one of the great factors in science. Specifically, in examining the survey o…

    Bank capital shock propagation via syndicated interconnectedness

    Nirei, Makoto : Julián Caballero : Vladyslav Sushko
    BIS Working Papers No 484 Bank for International Settlements （2015/01/27）

    Loan syndication increases bank interconnectedness through co-lending relationships. We study the financial stability implications of such dependency on syndicate partners in the presence of shocks to banks' capital. Model simulations in a network setting show that such shocks can produce rare events in this market when banks have shar…

      Nirei, Makoto
      『Theoretical Economics : journal of the Econometric Society』 forthcoming （2014/10/23）

      This study demonstrates that the interactions of firm-level indivisible investments give rise to aggregate fluctuations without aggregate exogenous shocks. When investme…

        RIETI ディスカッションペーパー 14-E-035 経済産業研究所 （2014/06/30）

        本稿は、企業間サプライチェーンが外生的なショックを伝播させる効果について定量的推計を試みる。企業間取引ネットワークデータと、東日本大震災による津波の地理的経緯度データを組み合わせることにより、浸水被害を受けた企業と直接・間接の取引関係にあった非被災地企業群を識別し、その売り上げの震災前後の変化を、取引関係にはなかった非被災地企業群の売上…

          Supply Chain Disruptions: Evidence from the Great East Japan Earthquake

          CARVALHO,Vasco M. : Makoto Nirei : Yukiko Saito
          RIETI Discussion Paper 14-E-035 Research Institute of Economy, Trade and Industry (RIETI) （2014/06/30）

          This paper quantifies the spillover effect of exogenous shocks, such as earthquakes, on other firms through the supply chain network. Combining micro data on inter-firm transaction networks and geographic information systems, we examine firms' sales growth and transaction relationships outside the tsunami-hit areas before and after the…

              Management of Science, Serendipity, and Research Performance: Evidence from Scientists' Survey

              WP#13-13 一橋大学イノベーション研究センター （2013/05/13）

              This study investigates the impact of management style on research performance in science. If a managerial role is played by a leading scientist in the research team, that is considered management-research integration. If not, we consider that management and research are separated. We found that separating the managerial and research r…

                This paper demonstrates that the interactions of rm-level indivisible investments give rise to aggregate uctuations without aggregate exogenous shocks. I develop a method to derive the distribution of the aggregate capital growth rate by embedding a ctitious tatonnement in a branching process. This method shows that idiosyncratic …

                                      This paper analytically demonstrates that the tails of income and wealth distributions converge to a Pareto distribution in a variation of the Solow or Ramsey growth model where households bear idiosyncratic investment shocks. The Pareto exponent is shown to be decreasing in the shock variance, increasing in the growth rate, and increa…

We investigate an extensive panel data set on Italian manufacturing firms. We first show that the fraction of firms that experience a large investment rate in a region-year is distributed exponentially…
