Knowing the effects of economic policies undertaken by state and local governments is important because they sometimes have significant impacts on society. If you learn about economic methods, you will know what these effects are specifically and be able to avoid making the wrong policy decisions should you become a government employee or take charge of policy implementation. In this sense, learning economics is essential.
