Select the statements below that are consistent with the input choice decisions of profit-maximizing competitive firms and monopolies. Choose one or more: A. For competitive firms, the marginal revenue product of an input equals the value of the marginal product. B. For a monopoly facing a downward-sloping demand curve, the marginal revenue product of an input equals the value of the marginal product. C. Monopolistic firms choose inputs of production at the point where the marginal revenue from each input equals the marginal cost. Competitive firms do not. D. Competitive firms and monopolies choose inputs of production at the point where the marginal revenue from each input equals the marginal cost. E. If the demand for a product is perfectly elastic, all else being equal, the optimal amount of an input of production is the same for a monopolist as it is for the competitive market as a whole. F. Competitive firms choose inputs of production at the point where the marginal revenue from each input equals the marginal cost. Monopolies do not.

The hawthorne works was a large western electric factory with 45,000 employees. during the 1920s and 1930s, hawthorne works was the site of some well-known industrial studies. in one of the studies, researchers investigated the impact of different working conditions on worker productivity. prior to the start of the study, researchers secretly measured workers' productivity for several weeks. then researchers chose two workers, who then chose their own teams. the teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). for each of these changes in working conditions, the researchers measured the effect on productivity. for some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity.why did the researchers secretly measure the workers' productivity before creating the two treatment groups? a, to create similar treatment groups so that a cause-and-effect relationship could be establishedb, to draw conclusions about the productivity of all workers in the plant based on the test groupsc, to directly control for confounding variablesd, to provide a baseline for measuring worker productivity
