In this study, the famous economist J.M. Keynes's “Investment Multiplier” concept, the relationship between factors such as production, consumption and environment of confidence in an economy has been examined. Production and consumption are both the causes and the result of economic activities. Today, it becomes easier to reach information with the development of communication technology. Now, economic units prefer to exchange information based on robust data rather than estimation in making decisions regarding production and consumption. Therefore, the element of trust is so important that it cannot be neglected by both political and economic authority. Variables such as economic confidence index, consumer confidence index and real sector confidence index are indicative for producers and consumers. In addition, although full employment conditions are valid in an economy, it is not possible to achieve economic recovery unless the confidence environment is established. Monetary authority should first determine this negative situation and should take precautions accordingly. If insecurity is entirely due to a lack of demand, it would be appropriate to follow the demand-increasing monetary and fiscal policies. But, if the distrust to economy is due to social, political or external sources, following transparent policies that are explanatory to public with sound findings, determining definite pudential macro economical objectives, and foremost economical power informing both the producer and the consumer within the legaslative regulations that they will not be harmed would be beneficial. Based on this fact, it has been decided to do a research on the Turkish economy. The importance of economic trust environment is emphasized with this study. The analyses were performed by using “Johansen Cointegration Test”. As a result, It is determined as a long term relationship between economic confidence index, the real sector’s and consumer’s confidence indices in Turkey like mentioned in the literature. In this context, as economic confidence increases, production and consumption are increasing with a multiplier effect.
