The main goal of this work is to develop an empirical investigation on the occurrence of a sanitary crisis with data of cases and deaths of Covid-19, and their possible impact on the exchange rate volatility for the BRICS with daily data from February 20, 2020, to February 28, 2022, using ARDL, FMOLS and DOLS models. The results indicate that increases in the number of confirmed cases and deaths are associated with lower levels of exchange rate volatility, indicating that monetary and fiscal policies were inefficient in the context of a generalized health crisis in directing capital flows, and since the Covid-19 crisis is a global one, during the period of analysis there was a relative exchange rate stability, in other words, a lower exchange rate volatility.

Para los flujos comerciales de maíz entre México y Estados Unidos los movimientos en la tasa de cambio son importantes, con algunas otras variables. Con el objetivo de contribuir con información relevante sobre el impacto de la tasa de cambio sobre el comportamiento de los flujos comerciales de maíz, en un contexto de subsidios a la producción, además de generar información relevante para la toma de decisiones de política económica. Para lo cual se analizó un modelo de maximización de la utilidad esperada y se estimó una función de demanda por importaciones de maíz a partir de un análisis de cointegración y un modelo vector de corrección de error (VCE). Los resultados mostraron que los cambios de la tasa de cambio real tienen efecto positivo sobre los flujos comerciales, en tanto que la volatilidad de la tasa de cambio ejerce un efecto negativo sobre dichos flujos. Los resultados de la prueba de hipótesis indicaron que tanto los cambios en la tasa de cambio real como la volatilidad tienen un efecto significativo sobre los flujos de comercio de maíz entre México y Estados Unidos.

Companies in the subsector of construction listed on the Mexican Stock Exchange (BMV) are focused on building infrastructure and housing, this is one of the reasons why they were not affected drastically during the crisis of subprime loans 2007- 2008. Some of these contractors use foreign currency debt in its capital structure. Alongside, the dollar's value has increased more than 30% for the period 2014-2015. This research aims to test the effect of the dollar price increase on the capital structure of the 16 construction companies listed on the BMV. The research was conducted in three stages. First, the structure and cost of capital of each and every one of the 16 construction companies was determined. Later, capital costs were grouped into two segments, the first for the period 2012-2013 and the second for the period 2014-2015, and in the third stage the cost difference was calcullated before and after the period when the dollar price increased using a t-student test. The results show that statistically, some companies, had a significant increase in their capital cost mainly due to the level of leverage employed in dollars. Others, despite maintaining high levels of leverage in foreign currency and probably due to the use of mechanisms and instruments for exchange risk coverage considered as part of the management of the managers of these companies, did not increase it so significantly.

The advent of the international crisis in 2008 showed not only the fragility of the global financial system and its lack of regulation, but also how the indiscriminate use of derivatives may increase the financial risk of large companies, both national and multinational ones. These instruments were considered one of the villains of the current crisis. The present work pretends to show how its use can preserve the financial health of companies. The focus takes place in foreign exchange derivatives because they are widely used by companies operating internationally . We analyze the main instruments, their uses, benefits and how they might affect the value of the company that use in an appropriate way, i.e., for protection -- in order to keep healthy the entire flow of operational and financial company --, as well as examples of companies that used them for speculative purposes, without reaching, however, the expected results.
