Abstract

The current study investigated if the ICMS tax substitution regime had impacts on the prices used by wineries in Vale dos Vinhedos. The sample includes companies located in the region of Vale dos Vinhedos and it was limited to the wines cabernet sauvignon, merlot and chardonnay. The analysis object period was from 2007 to 2012 and in 2009 the effects of this taxation regime on the sample`s companies began. The general aim of the study was to investigate the possible impacts on the prices used by the wine industry with the adoption of the taxation regime. The specific aim was to investigate this regime and its influence on the selling price formation for the companies. As methodological procedure, the variance analysis Anova Single Factor and test t from student were initially used to identify the differences between the average price of the wines in the period of the sample. Later, a regression was elaborated with the variables by the fixed panel data method. The results of the statistical model indicate positive relation of the variable tax substitution (ST) with the variable dependent price (PRICE), with statistical significance presented by the tests Durbin-Watson and Adjusted R-Squared. It was concluded, by the results presented in the statistical methods, that the tax substitution regime caused impacts in the prices used by the wineries, this way, it can also impact the demand for the product in the market and consequently, the competition in the sector. Such results cannot be generalized because of the peculiarity of other producing regions or economic sectors. It`s advisable, for future studies, the analysis of other wine producing regions in order to be able to compare to the results presented in this study and also the analysis of other economy sectors affected by the same taxation technique.
