- ÍtemMacroeconomía y su efecto sobre el desempeño financiero de las empresas de Colombia 1995-2015Daza Saavedra, Julian Mauricio; Flores Bolaños, JaimeThe objective of this document is to quantify the macroeconomic drivers of financial performance for Colombian companies for the period 1995-2015. For this, information was taken from the Superintendency of companies (a little more than 13,000 records per year) and the effect of macroeconomic performance on companies was estimated on the indicators of situation, activity and indebtedness. These indicators were defined taking into account the transmission mechanisms of monetary policy (Mishkin, 1995) and fiscal (Mounford & Uhlig, 2005). The situation indicators included the current Reason (Current assets / Current liabilities), Net working capital (current assets-current liabilities) and Debt ratio (Total liabilities / Total assets). In the activity indicators, income control was defined (Total revenues / Total expenses + Total costs) and Financial indebtedness (Financial Obligations / Total Revenues) while the Total Leverage (Total Liabilities / Equity) was built in indebtedness
- ÍtemPropuesta de modelo Logit para determinar la influencia de las comorbilidades y los síntomas en el desarrollo del diagnóstico de Covid-19 mediante la prueba PCR en Colombia(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Daza Saavedra, Julian Mauricio; Diaz Herrera, Cristian CamiloThrough a Logit model, this article proposes to address the inference that symptoms and comorbidities have in the result of the CRP test for the detection of COVID-19 in Colombia. To do this, is used the data of 8667 people who took the test between April and December of the year 2020. Using these data, it is possible to determine the most common symptoms and comorbidities that the people who have taken the test presented and thus establish their influence on obtaining a positive or negative diagnosis from the CRP test. By obtaining how much the comorbidities and symptoms affect in the diagnosis of the test, it is easier to understand the importance of the care that must be taken so as not to spread the disease further.
