We analize the Mexican peso-US dollar exchange parity the volatility using three models in order to evaluate the exchange rate risk performance and the these models capability of modeling such risk. The period June 21st, 2017 to June 21st, 2022 is marked by singular events that pressed this exchange rate parity, making it of great interest to study the tools that can be used to measure this uncertainty besides the study of the exchange rate uncertainty itself. The arrival of a leftwing politician to the presidency was an unprecedented event. At the beginning of 2020 the price war in the oil market and the emergence of the COVID-19 pandemic had important effects in the world economy. Finally, the war in Ukraine added pressures to the international trade of raw materials, inducing an inflationary episode with bad expectations about the economic performance around the world. The exchange rate scenarios posed by the aforesaid events provide us with a natural context to test which of the posited volatility models offers a better fit. Unanimously, the results under the three models suggest that during the first year of the President López Obrador period the exchange rate uncertainty was reduced compared to previous levels, returning again to those minor levels after the forced closure of economic activities due to the emergence of COVID-19, even though the exchange fluctuation band has been slightly higher than before the pandemic and the war on East Europe.

Through a quantile regression, it is shown that from 1990 to 2018 the impacts of business investments, dollar debt and the exchange rate are differentiated for the various levels of exchange earnings of a group of Mexican companies. The value of the dollar and foreign currency debt negatively impact earnings, and investments in property, plant and equipment, and net working capital have a greater influence on such earnings. The relationship between foreign exchange earnings and investments in recent, intangible assets and net working capital has not been previously studied. These results can be useful for investment planning as a means of managing the risk of foreign exchange losses. [ABSTRACT FROM AUTHOR]

This paper shows the analysis carried out to determine which macroeconomic risk factors affect the delinquency of the mortgage portfolio securitized in Mexico. Hypothetical risk factors were constructed based on the review of relevant literature and the analysis of principal components of a set of economic variables. Using econometric tools, the relationships between delinquencies and hypothetical risk factors were analyzed, as well as between the former and the economic variables. Evidence shows that economic openness and international money market conditions are risk factors that can affect delinquency. Evidence was also found that the postulated variables are relevant to explain the delinquency of the portfolio studied. [ABSTRACT FROM AUTHOR]

Este trabajo examina la hipótesis de la convergencia de precios intranacional de 15 ciudades mexicanas hacia la ciudad líder, el Distrito Federal. Las pruebas de estacionariedad en panel aplicadas al diferencial de precios de las ciudades con respecto a la ciudad líder revelan que éste es estacionario, validando de esta manera la hipótesis de convergencia de precios. Por otra parte, las pruebas de estacionariedad en panel aplicadas a los índices de precios de las ciudades, sugieren que esta variable posee una raíz unitaria. La evidencia sugiere que los índices de precios de las ciudades y el índice de precios del Distrito Federal se encuentran cointegrados. Por otro lado, las estimaciones efectuadas muestran que los parámetros estimados, tanto de manera individual como para el panel en su conjunto, son muy próximos a la unidad. [ABSTRACT FROM AUTHOR]
