To reduce market concentration in agriculture, many states have enacted policies to entice new prospective entrepreneurs into farming. Among these are tax credits for existing farm owners who lease or sell farmland to “beginning farmers.” These subsidies aim to compensate the lessor for the additional risk associated with leasing land to a new farming enterprise. This paper investigates the effect of Iowa's Beginning Farmer Tax Credit program on land leased to farmers, farm operators' average age, and various metrics of non-corporate farm operations. Our point estimates suggest very small effects of the program on Iowa's prevailing farm trajectories with a budgetary cost of more than $100,000 per added independent farm.</p>","PeriodicalId":8004,"journal":{"name":"Applied Economic Perspectives and Policy","volume":"48 4","pages":"1048-1068"},"PeriodicalIF":3.6,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aepp.70075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148710469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban. A discrete choice experiment was conducted with Swedish crop farmers (<i>N</i> = 875), considering three policy attributes (commitment duration, maximum allowable percentage of mixed legume plants, and subsidy payment levels), two alternatives (permission to sell or utilize cover crop biomass versus restrictions), and one treatment condition (glyphosate ban). A Latent Class Logit Model was employed to explore heterogeneity in farmers' willingness to grow cover crops. The analysis identified three distinct farmer groups: 29% are unlikely to grow cover crops regardless of policy attribute design, 41% are predisposed to adoption irrespective of policy attributes, and 30% are influenced by subsidy payment scheme design. For the latter group, a glyphosate ban should reduce their willingness to grow cover crops.

Empirical results show that each additional patent transferred from an innovator to a recipient country increases the recipient's exports to the innovator, primarily through growth along the extensive margin. Transportation-stage technologies, which facilitate export market entry in the technology-recipient country, exert a stronger effect on exports than production-stage innovations.
