Farmers who grow Robusta coffee in Chumphon Province are highly dependent on seasonal migrant labor from northeast regions during the harvest season. However, recent changes in labor market conditions and the development of non-agricultural sectors across the country have increased the difficulty in finding seasonal farm labor, and this acute labor constraint may affect coffee production. This study examines the effects of this labor constraint on production outcomes and labor allocation. To identify constraints and the allocation of inputs, especially labor input, a quadratic production function is employed to estimate marginal productivity. An augmented inverse probability weighting estimator is then utilized as a double robust to estimate the average treatment effect. Our estimations found that the difference in the marginal productivity of labor inputs is not significant; however, the labor hiring constraint has a negative and statistically significant effect on coffee production. Thus, the exchange of labor information and providing information on coffee picking practice in the site are needed. Additionally, as farmer groups serve an important role in building stronger social ties and decreasing labor constraints, programs that implement technology and tools for supporting unskilled harvesting labor, labor information, and coffee farm practices should be implemented through farmer groups communities.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "本研究は、タイ南部のチュンポン県のコーヒー栽培農家が近年直面している収穫労働の確保の困難性が生産に及ぼす影響を数量的に検証した。同地域では、もともと東北部から移り住んできた人々がコーヒー生産を担っており、収穫時期に必要となる労働力についてはこれまで東北部からの出稼ぎ労働力に頼ってきた。本研究は、この労働制約の起こりやすさはランダムなものではなく各農家の労働需要や収穫作業条件によって決まることを踏まえて、また雇用労働制約の有無による農家の対応をみるために、二重にロバストなAIPW 推定量によってquadratic な生産関数を推定し、雇用労働制約の有無の違いによる家族労働と雇用労働の限界生産性を比較することで、雇用労働制約がある場合の家族労働の補完的な投入の程度について検証した。結果、雇用労働制約の有無によって有意な限界生産性の差は見られないものの、雇用労働制約が有ることで有意に生産量が低くなることがあきらかとなった。", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学農学国際教育協力研究センター", "subitem_publisher_language": "ja"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.50907/jicad.19.0_2", "subitem_relation_type_select": "DOI"}}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "2436-2786", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kwanmuang, Kanjana", "creatorNameLang": "en"}, {"creatorName": "クワンムワン, カンジャナ", "creatorNameLang": "ja"}]}, {"creatorNames": [{"creatorName": "Lertjunthuk, Laddawan", "creatorNameLang": "en"}, {"creatorName": "レルジュンタック, ラダワン", "creatorNameLang": "ja"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-01-17"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Vol19_02-16_Original_Kanjana.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 1200000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2001953/files/Vol19_02-16_Original_Kanjana.pdf"}, "version_id": "e6efc44c-ec6a-4a34-8f4a-74aa35520f1f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "labor constraint", "subitem_subject_scheme": "Other"}, {"subitem_subject": "augmented inverse propensity weighted estimator", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Robusta coffee", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Thailand", "subitem_subject_scheme": "Other"}, {"subitem_subject": "労働制約", "subitem_subject_scheme": "Other"}, {"subitem_subject": "拡大された逆傾向重み付け推定量", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ロブスタコーヒー", "subitem_subject_scheme": "Other"}, {"subitem_subject": "タイ王国", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "The Effect of Harvesting Labor Constraints on the Production of Robusta Coffee Farmers in Chumphon Province, Thailand", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "The Effect of Harvesting Labor Constraints on the Production of Robusta Coffee Farmers in Chumphon Province, Thailand", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1642383128608"], "permalink_uri": "http://hdl.handle.net/2237/0002001953", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-01-17"}, "publish_date": "2022-01-17", "publish_status": "0", "recid": "2001953", "relation": {}, "relation_version_is_last": true, "title": ["The Effect of Harvesting Labor Constraints on the Production of Robusta Coffee Farmers in Chumphon Province, Thailand"], "weko_shared_id": -1}
