9. In the model for hedonic price theory A) every market equilibrium matches a producer and a consumer at a particular amount of the attribute z of the good such that at z the bid function of the consumer and the offer function of the producer are tangent B) offer functions of the producer are increasing in profits. C) the slope of the hedonic price function tells us by how much the price of the good goes up if the attribute under consideration is increased by one marginal unit. D) producers differ only through their cost functions while consumers differ only through their utility functions E) several of the above In the multiple linear regression model A) the interpretation of the slope coefficient of the first regressor tells us by how much the mean of the left hand side variable (regressand) changes if the regressor is changed by one unit keeping all the other regressors fixed. B) the effect of a marginal change in a regressor on the mean outcome of the left hand side variable (keeping all the other regressors fixed) cannot depend on the current value of the regressor C) the OLS estimator is found by minimizing all the estimated residuals. 10 D) the key assumption is that there is a regressor that is uncorrelated with the error term. E) several of the above.
Multiple Choice: Choose exactly one of the five options. 7. A) In 2021, in the US the biggest energy source for electricity generation was natural gas, followed by wind and solar. B) According to the latest IPCC report the two best options in terms of potential and costs to reduce worldwide emissions of Greenhouses gases by 2030 are wind energy and bioelectricity. C) Carbon capture and storage can be used to achieve net emissions reduction of Greenhouse gases; however the technology is more expensive than using solar energy for net emissions reduction. D) In 2021, in the US all renewable energy sources account for more than 35% of electricity generation E) Several of the above. 8. Suppose there is a technological innovation that reduces the marginal abatement cost for a pollutant. If that pollutant is regulated with a "cap and trade" program which of the following statements is TRUE. The supply curve of permits will shift to the left because of the lower level of pollution B) Polluting firms will have an incentive to adopt the costly new technology because they can reduce their purchase of pollution permits. C) The market price of a pollution permit will rise as polluting firms adopt the new technology D) The market demand for pollution permits will rise. E) It is impossible to tell how the permit market will be affected because we cannot tell how the demand curve for permits will shift. A)
