Elasticidade de oferta: um estudo sobre o índice para apartamentos da região centro-sul de Belo Horizonte

Price elasticity of supply is an economic concept that measures the influence of supply on market price fluctuations. Economically, this index is crucial for understanding market dynamics, as its calculation enables suppliers to adjust product availability in response to price changes or, alternatively, to modify prices based on supply levels. In real estate appraisal, price elasticity is essential for correcting distortions in market values, particularly when discrepancies exist between listing prices and actual transaction prices. These distortions occur when market value calculations rely solely on listing data, which tend to be overestimated. To address this issue, an adjustment factor referred to as the supply factor is applied to account for the bias introduced by exclusively using listing data in market assessments. This study aimed to calculate the price elasticity index for apartments in the central-south region of Belo Horizonte, utilizing the Direct Comparative Market Data Method. Data on listed and transacted properties were collected and analyzed to quantify the percentage difference between estimated values under listing conditions and actual transaction prices. The methodology incorporated advanced statistical techniques, including linear regression modeling and inferential statistical analysis, conducted using the INFER 32 software. The results highlighted the relevance of the price elasticity index in enhancing the accuracy of real estate appraisals. Beyond demonstrating the importance of correctly identifying the hedonic factors influencing property valuation, the study provided a comprehensive analysis of market behavior in the target region. Thus, this research contributes to improving transparency in real estate transactions, supporting developers, appraisers, and investors in making informed strategic market decisions.
