Consider how you have been working as a team, both in small classes and on your written assignments. In one paragraph, describe your greatest strength as a team and one aspect of teamwork that your team does especially well. In a second paragraph, describe one aspect of teamwork that your team can improve and how you will Work together to improve this aspect of teamwork in future small classes and assignments. The Laer curve 1; = R(t) proposes a simple theoretical relationship between a government's tax revenue R(t) and tax rate t: Ra) : we), where b(t) is the tax base for tax rate t 7 that is, the total dollar amount of economic activity taxable at tax rate t The dependence of b(t) on 2 comes from things like changes in people's spending habits or companies' investment plans based on the tax rate Because i represents a tax rate, it is restricted to be in the interval [0,1]. (For example, if you have a tax base of $20billion and a tax rate of %, $5 billion goes to the government through taxes, and $15 billion remains with the economic actors.) In this assignment, you may use without proof the assumption that b(t) is continuous on the interval [0,1] and differentiable on the interval (0,1) You may also look up terms and arguments online, though it is certainly possible to get full marks on the assignment without doing so. 2. (a) In a paragraph, explain why it is plausible that b'(t) 0 on the interval (0, 1)? Justify your answer in one or two paragraphs. You may assume that b'(t)
