In February 2020, a family of four required between $14,196 pesos and $15,667 pesos per month to obtain a salary that exceeds the welfare or poverty line. This is an income that most Mexican households do not obtain. There is little social mobility in Mexico, where three quarters of the population born in households at the bottom of the social ladder do not manage to rise above the poverty line, even so, I believe that it is advisable to pursue undergraduate and especially graduate studies. By 2020, a person with a graduate degree will receive 6.6 times more than a person with a primary school education, 4.5 times more than a person with a secondary school education, 3.8 times more than a person with a high school education and 2 times more than a person with a bachelor's degree. In terms of gender, women with high school, undergraduate and graduate degrees receive the equivalent of 70% of the salary of men.In December 2021, more than 1.8 million Instituto Mexicano del Seguro Social (IMSS) affiliates receive a salary higher than $30,170 pesos, of which more than 830 thousand receive a salary higher than $47,140 pesos, corresponding to 3.2% and 1.5% of the 56.9 million people that make up the economically active employed population (formal and informal).

This article discusses the effect of the oil shock on some OECD oil-importing countries such as Canada, France, Italy, China, and the United States and some OPEC oil-exporting countries such as Algeria, Iran, Kuwait, Saudi Arabia, and Venezuela. The model is estimated for the years 1976-2021. five annual variables are used for each country. The variables within the model include real oil prices, GDP growth, inflation, real wages, and real effective exchange rates. Real GDP is the main variable that shows the effects of oil prices on the economy, and the impact of oil prices on other model variables will indirectly affect economic activities. For this purpose, we estimate the vector autoregression model. Estimates obtained for different countries show that oil price shocks are one of the variables affecting economic growth. Also, in oil-exporting countries, oil shocks on economic growth are positive and negative in oil-importing countries. Also, Covid-19 is studied as an effective parameter in creating oil shocks.
