Can we use conjectural variation models to tell whether market power is the result of product differentiation or collusion? . Many research designs involve statistical tests – involve accepting or rejecting a hypothesis. Null (statistical) hypotheses assume no relationship between two or more variables. . Statistics are used to test null hypotheses. Intro:. This section is going to focus on relationships among several variables for the same group of individuals. In these relationships, does one variable cause the other variable to change?. Explanatory Variable. How can conjectural variation models help?. Alan Crawford and . Benoît. Durand. OFT Seminar. The questions. Can we use conjectural variation models to . measure empirically market power?. identify the source of market power? Can we use conjectural variation models to tell whether market power is the result of product differentiation or collusion? . Once you know the correlation coefficient for your sample, you might want to determine whether this correlation occurred by chance.. Or does the relationship you found in your sample really exist in the population or were your results a fluke?. a measure of the extent to which two variables change together..
