Field experiments

Business examples where field experiments would be appropriate are:

(i) a marketing manager wants to test the effects of different types of store displays on sales (i.e. would certain types of displays increase sales more than others);

(ii) a stock broker wants to study the effects of consumer confidence/diffidence on the investment patterns in short-term world market AAA funds before and after a war or major terrorist attack;

(iii) a Finance manager wants to study the effects of changes in current debt to long-term debt ratios, on stock values;

(iv) a manager wants to examine whether dyadic conflict is induced as a function of gender and race differences between the supervisor and the subordinate. In other words, is conflict experienced more when a woman or a minority subordinate reports to a European male supervisor, but not when a European male subordinate reports to a European male supervisor?
