A paper co-authored with Dr. Yasuyuki Todo has been published in EPJ Data Science. The paper entitled “Has Covid-19 permanently changed online purchasing behavior?” reveals that consumer purchasing behavior changes significantly at the beginning of a pandemic wave, but then returns to the previous wave with each successive wave.

I was invited to speak at CCSS School on Computational Social Science: Agent-Based Models (ABM) in Economics, Kobe University Research Center for Computational Social Science.

I was invited to give a talk at RIKEN’s “Fugaku” EXPANDS event. The lecture focused on supply chain simulation and how Fugaku can be utilized more in the future.

A paper co-authored with Yosuke Murase and Dr. Yasuyuki Todo has been published in Spatial Economic Analysis. The paper entitled “Supply-chain simulations for shaping lockdown policies” shows the importance of the combination and timing of urban lockdowns due to a pandemic.

Supply-chain simulations for shaping lockdown policies

To prevent the spread of COVID-19, many governments have imposed lockdowns. This practice has resulted in economic stagnation across broad areas because of the shock of the lockdown propagated to o…

Our paper, INOUE Hiroyasu and TODO Yasuyuki, ”Propagation of Overseas Economic Shocks through Global Supply Chains: Firm-level evidence” was introduced during the deliberations of the National Assembly, particularly in terms of the impact of having trade restrictions on China.

RIETI – Propagation of Overseas Economic Shocks through Global Supply Chains: Firm-level evidence

この論文は、グローバル・サプライチェーン、貿易の途絶、シミュレーションについて書かれています。RIETIディスカッション・ペーパー（DP）コーナーは、専門論文の形式でまとめられたフェローの研究成果を公開し、活発な議論を喚起することを目的としています。ポリシー・ディスカッション・ペーパーと比べて、より理論的・分析的・実証的な研究論文を収録しています。論文は、原則として内部のレビュー・プロセスを経て掲載されます。当コーナーに掲載されている論文は、頻繁に改訂されています。論文に述べられている見解は執筆者個人の責任で発表するものであり、経済産業研究所としての見解を示すものではありません。

Prior to the release of our research’s video on the NHK Special, an in-depth article to introduce the broadcast was posted on the NHK website.

An NHK special broadcast on March 5th, 2023 featured our estimate of real economy losses along the lines of a “half-crack” that would be caused by two separate Nankai Trough earthquakes.

南海トラフ巨大地震 第2部 “最悪のシナリオ”にどう備えるか – NHKスペシャル

ドラマのシナリオを監修した福和伸夫・名古屋大学名誉教授をゲストに迎え、ドラマの出演者と共に、南海トラフ巨大地震への備えを考える。「都市を襲う津波からどう逃げるか」「避難に猶予がない地域でどう命をつなぐか」「長期の避難生活をどう乗り切るか」「企業活動の継続に必要な備えとは」など、対策の現場のルポとともに、スタジオでの解説を交えながら、「日常に防災を取り入れる」ことの大切さと実践のヒントを提示する。

A video introducing our research collaboration (JSOL Inc. and RIKEN MATHEMATICS INC.) is now available.

I had a presenation at the Annual Modeling and Simulation Conference (ANNSIM) 2023. The conference was a great opportunity for researchers in this research area to exchange information on various simulations. The location was Mohawk University in Hamilton, Canada, which was a university, but with nothing around it. It was quite an unusual experience for me.
