Purpose: This study aims to analyze the relationship between the abnormal return and R&D expenses in Brazilian public firms. Originality/value: The determinants of firms' abnormal return provide information relevant to investors' decision-making. In this context, we verified whether the innovation, measured by R&D expenses, could be a key factor for the abnormal returns in Brazilian firms. Design/methodology/approach: We analyzed Brazilian public firms, from 2009 to 2016, by panel data regressions, in a sample composed by 1,597 firm-year observations. We collected information about R&D expenses in the footnotes. When a firm only mentioned about R&D expenses but did not disclose spent value in the Income Statement, we consider that the firm did not invest in the period and we attribute zero as a value. We highlighted that few firms mentioned R&D expenses in their footnotes and/or declared that they invested in R&D, only 44 firms in all sample, pointing the importance of better disclosure practices of these investments. Findings: The results demonstrate a negative and statistically significant relationship between innovation and the abnormal return. That is, current R&D expenses lead to a lower current abnormal return. It could be linked with the fact that R&D expenses tend to produce returns just in longer periods, demanding more time to recover these investments, due to their complex characteristics related to accounting measurement of R&D expenses. Consequently, an abnormal return could be perceived only in subsequent periods.

This paper revisits a traditional issue in literature on franchising: the contractual mix (i.e., the proportion between franchised and companyowned stores). We analyze 270 Brazilian chains to better understand the Brazilian scenario. We stress the dynamics of this proportion over time considering the perspective of monitoring costs and the difficulty of access to resources as possible explanations. Considering the moment of the Brazilian economy, it is pertinent and opportune to investigate the behavior of the chains in times of turbulence. Panel data covering the 2011-2016 period was analyzed through econometric tools. The results corroborate aspects related to monitoring and incentives advocated by the agency theory, that is: costs of monitoring in elevation due to the geographic dispersion induce a greater proportion of franchised stores. In addition, the concept of dispersion is extended to capture socioeconomic aspects of the different regions occupied by the chains. Effects related to restriction to scarce resources are also noted, but in a less unambiguous way.
