Question 16.61

16.61 French tourism economy.

Refer to Exercise 16.47 (page 16-27). The study also considered two other components of ski resort efficiency: technological change (TECH) and technical efficiency change (EFFCH).

ski

  1. With relationship to the TECH measure, the researcher states: “There is no reason to believe that size differences affect technological change.” Is this statement consistent with your results? Explain.
  2. With relationship to the EFFCH measure, the researcher states: “A relationship between size and technical efficiency change can be made.” Is this statement consistent with your results? Explain.
  3. With respect to the EFFCH measure, the researcher concludes: “These observations permit the conclusion that large ski resorts are better organized and ensure better management than medium and small ski resorts.” Explain how the data support this conclusion.

(a) This statement is correct. H0: TECH values have the same distribution in all groups. Ha: TECH values are systematically higher in some groups than in others. , The data do not show systematic differences in TECH values across resort sizes. (b) This statement is correct. H0: EFFCH values have the same distribution in all groups. Ha: EFFCH values are systematically higher in some groups than in others. , The data show systematic differences in EFFCH values across resort sizes. (c) The rank sum for the large resort size is much larger than expected under H0.
