Question 5 In my paper about climate change and grape growers' revenue/profit in the European Union (see PPT file) I specify a log-linear equation and find that In (It) = 0.221 . Temp - 0.006 . Temp + ... , where Temp is measured in C. a) Based on these coefficients, calculate the profit maximizing temperature (which may be slightly different from what is provided in the Table due to rounding). Provide a precise number with 3 decimals! b) Now assume I had used a linear equation and had found the same coefficients, that is IT = 0.221 . Temp - 0.006 . Temp2 + .... What is the profit maximizing temperature now? c) Based of the original log-linear equation In(n) = 0.221 . Temp - 0.006 . Temp + ..., what is the profit it if a plot of land experiences a (growing season) temperature of 24 C. What is the profit if temperatures increase to 26C? What is the percentage decrease in profits
