Using the per-worker production function with "capital per worker" on the x-axis and "output per worker" on the y-axis, answer the following questions: - Assume an influx of working-age immigrants enters the country. The per-worker production function would and a(n) in output per worker would occur. - Assume technology improves in the country. The per-worker production function would and a(n) in output per worker would occur. - Assume an increase in capital machinery was produced in a previous period, The per-worker production function in the subsequent period would and a(n) in output per worker would occur. - Assume government policies change such that productivity is hindered. The per-worker production function would and a(n) in output per worker would occur
