  This paper provides an overview of the Japanese government response to the COVID-19 crisis in terms of the fiscal measures taken between January and June 2020. As the crisis intensified, the government passed emergency budgets with a total value exceeding 10 percent of gross domestic product. One of the main programs was an unconditional cash transfer for households in the amount of 100,000 JPY (i.e., 909 USD) per resident. In addition, to prevent layoffs and bankruptcies, the government created and expanded various loan and subsidy programs to support firms and workers. Other existing social programs and local economic policies are also reviewed.

  Over half a billion children lack adequate lighting and use dim, smoky and dangerous kerosene-based lighting for their evening studies. This article examines the conventional wisdom that the brighter, clean, safe and zero-marginal-cost light of solar lamps enhances children’s learning outcomes. In a randomised experiment, unexpectedly, solar lamps lowered test scores by five points out of 100 (0.25 standard deviation), but increased reported study time by approximately 30 minutes per day. This may be due to flickering from lack of full charge, lowering their productivity. The nationwide learning assessment suggests that solar lamps likely have an insignificant effect on educational attainment.

  社会科学の実証研究において、否定的な結果が肯定的な結果に比べ発表されにくいという「出版バイアス」が存在し、エビデンスの統合における重要な問題であるという認識が高まっている。出版バイアスは、利己的な動機を持つ研究者が自分の研究結果をよりよく見せようとする結果だと一般的に考えられている。この考えに基づき、特定の結果報告パターンを仮定したメタ分析のバイアス補正方法が提案されてきた。本研究では、情報処理のための認知的制約を持つ論文読者に、分かりやすく研究結果を伝えたいという利他的な動機からも出版バイアスが生じるという新しい仮説を、ゲーム理論を用いて検討する。この研究者と読者の間の情報伝達モデルは、結果報告パターンを従来の単純な仮定では説明できないことを示唆している。そこで、この情報伝達モデルに基づいて、特定の仮定に依存しない、既存の手法より頑強な出版バイアスの補正手法を新たに開発し、その有効性を検証をする。
