The methodology is mainly theoretical: we first review that, when only transaction prices can be observed, the distribution of private valuations is irregularly identified. The sample bias produced by nonparametric estimators will affect all functionals of practical interest. We provide simulations for a best-case scenario and a worst-case scenario. Our results show that, compared to nonparametric approaches, the approximation of such functionals developed using EVT produces more accurate results, is easy to compute, and does not require strong assumptions about the unobserved distribution of bidders' valuations. It is recommended that financial operators working with auctions use this parametric approach when facing incomplete datasets. Given the difficult nature of the analysis, this work does not provide large sample properties for the proposed estimators and recommends the use of bootstrapping. This article contributes originally to the literature of structural estimation of auction models providing a useful and robust parametric approximation.","PeriodicalId":402333,"journal":{"name":"Abril - Junio 2021","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124729589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The period examined includes monthly data from January 2002 to December 2019. A vector autoregressive model (VAR) is used, which includes formal employment at the city level as a proxy to economic development, interest rates, nominal exchange rates, each analyzed city’s CPI, U.S. consumer prices, energy commodity prices and control variables such as service sector employment share and large firm employment share. Impulse response functions are constructed. Results for the 2002-2016 period indicate that exchange rate changes primarily affect border cities. Different arguments are included to justify such results. Pass-through values are also found to increase in general for all cities when the period 2017-2019 (January 2017 when important gasoline price shocks started previous its price liberalization in December 2017) is included in the regressions.","PeriodicalId":402333,"journal":{"name":"Abril - Junio 2021","volume":"47 20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117245665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Se trata de un planteamiento técnico de la teoría del comportamiento libre de arbitraje de tasas de interés de distintos vencimientos. Los modelos de tasa corta están ganando relevancia en la actualidad por su capacidad para describir y explicar la existencia de tasas de interés negativas como se ha observado en Europa y Asia. Las condiciones económicas actuales, en un entorno de incertidumbre generado por una recesión económica global, afectan el comportamiento de las tasas de interés, lo cual invita a realizar una revisión más cuidadosa de los factores que influyen en la dinámica de las mismas. Este artículo tiene como objetivo revisar las tendencias y perspectivas de los modelos de estructuras de plazos y destaca algunas áreas para futuras investigaciones.","PeriodicalId":402333,"journal":{"name":"Abril - Junio 2021","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116824341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
