Loginova, Daria Portmann, Marco Huber, Martin 2021 Causal estimation of the short-term effects o tariff-rate quotas (TRQs) on veg­etable producer prices is hampered by the large variety and different growing sea­sons o vegetables and is therefore rarely performed. We quantify the effects of Swiss seasonal TRQs on domestic producer prices of a variety of vegetables based on a difference-in-differences estimation using a novel dataset of weekly producer prices for Switzerland and neighbouring countries. We find that TRQs increase prices of most vegetables by more than 20% above the prices in neighbouring coun­tries during the main harvest time for most vegetables and even more than 50% for some vegetables. The effects are stronger for more perishable vegetables and for conventionally produced ones compared with organic vegetables. However, we do not find clear-cut effects of TRQs on the week-to-week price volatility of vegetables although the overall lower price volatility in Switzerland compared with neighbouring countries might be a result o the TRQ system in place. application/pdf https://folia.unifr.ch/global/documents/328593 https://folia.unifr.ch/documents/328593/files/assessingtheeffectsofseasonaltariffratequotasonvegetablepricesinswitzerland_journalofagruculturaleconomics_1.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1111/1477-9552.12424 info:eu-repo/semantics/altIdentifier/issn/0021-857X info:eu-repo/semantics/openAccess Rights reserved Journal of Agricultural Economics. - Wiley. - 2021, vol. 72, no. 2, p. 607-627 Agricultural trade policies Difference-in-differences Inverse probability weighting Price stability Price volatility Seasonal production Stabilisation poli­cies Swiss agriculture Tariff-rate quotas Vegetable production info:eu-repo/classification/udc/33 Assessing the Effects of Seasonal Tariff‐rate Quotas on Vegetable Prices in Switzerland http://purl.org/coar/resource_type/c_6501
