Los impuestos son, económica y estadísticamente, determinantes importantes de la estructura de capital de las empresas y, por tanto, no son un factor de segundo orden en las decisiones de endeudamiento de las empresas. Así lo prueba el trabajo de investigación realizado al que nos referiremos en las siguientes líneas.

The relevance of risk aversion as the key factor explaining the fluctuations of the economy is receiving increasing attention since the Great Recession. The role of financial shocks in the economic fluctuations and their associated amplifying effects are crucial aspects in the monetary policies followed by central banks around the world. The underlying mechanism behind these effects is directly linked to the time-varying behavior of risk aversion, especially during recessions. The reason is that risk aversion is strongly related to the behavior of the expected market risk premium, which is a fundamental input in the cost of capital and investment decisions of firms through the business cycle. In this research, we present an analysis of the interplay between the expected market risk premium, time-varying risk aversion, and economic uncertainty for the Spanish economy. We estimate risk aversion from aggregate consumption of Spanish households, while the expected market risk premium is extracted from options traded on the IBEX-35 index. Note that we put together variables from the real economy and financial markets. We show that both variables are positive and significantly related, clarifying the important connection between the real and financial sectors of the Spanish economy. More precisely, we show that both risk aversion and the expected market risk premia at alternative horizons are counter-cyclical, and that the slope of the term structure of the expected market risk premium is steeply downward sloping during recessions. Moreover, we find that risk aversion significantly amplifies the effects of adverse economic uncertainty shocks on the expected market risk premium. Therefore, it should not be surprising the collapse of financial prices when there is shock in uncertainty amplified by the increase in risk aversion. The corresponding rise in the expected market risk premium explains the drop in equity prices during bad economic times. The persistence of these effects depends on the nature of the economic crisis. In this framework, we understand both the initial dramatic drop in asset prices provoked by the exogenous COVID-19 crises, and the subsequent recuperation. To conclude, the positive association between uncertainty shocks, risk aversion and the expected market risk premium has extremely important consequences for the investment and output growth fluctuations of the Spanish economy.
