Rent-seeking in an emerging market: A DSGE approach

Due to the fact that rent-seeking is by definition an unobservable variable, measuring its size and evolution over the business cycle can be a daunting challenge. In this article, by embedding rent-seeking behavior in an otherwise standard open-economy DSGE model, we are able to derive a quarterly time series of this variable (expressed as a percentage deviation from the trend) for an emerging economy such as Brazil. The estimated series, spanning the period 2002Q1?2017Q4, shows a strong positive correlation with the “Commodity Super Cycle” of the 2000 decade and falls as a result of some political scandals and their ensuing investigations, among other driving forces. We also rely on the same model to assess how several shocks hitting the economy affect both rent-seeking and the relevant macroeconomic variables in our model. Barring monetary expansions, increased exports and higher income transfers to households, expansionary shocks are associated with lower rent-seeking activity. Factoring in these two sets of results, the upshot is that rent-seeking behavior shows a pattern of procyclicality in the Brazilian economy.     

Word-of-mouth communications in marketing: a meta-analytic review of the antecedents and moderators

Although word-of-mouth (WOM) activity has been studied as an outcome variable of other constructs such as satisfaction, less attention has been given to the antecedents and moderators of WOM when considering WOM as a central construct. Hence, we propose a model of WOM antecedents and moderators using a meta-analytic review. The results show that all antecedents have significant effects on WOM activity, with customer commitment showing the strongest effect. The following hypotheses are also supported: (1) WOM valence is a significant moderator, (2) cross-sectional studies show a stronger influence of satisfaction and loyalty on WOM activity than longitudinal studies, and (3) studies of WOM behavior show a weaker link between loyalty and WOM activity than studies of WOM intentions. In addition, we show that satisfaction has a stronger relationship with positive WOM than loyalty, whereas (dis)loyalty has a stronger relationship with negative WOM than does (dis)satisfaction. We discuss this finding based on the different natures of positive and negative WOM. This article is based on the first author’s dissertation.     

Demographics and asset returns: does the dynamics of population ageing matter?

The empirical connection between the population age-structure and financial asset returns has been so far investigated with special focus on the US, whereby weak or disparate results are obtained. This paper aims to assess whether this connection is affected by the demographic dynamics. To this end the analysis is based on a stylized overlapping generation model and on the empirical investigation for Italy, which is experiencing one of the most pronounced ageing in the world and, specifically, steeper than the US one. Following the approach used for the US, stock returns and Government bond yields are regressed over demographic and/or control variables using annual data over 1958–2004. Results for Italy are more clear-cut and thus support the importance of the country-specific age-dynamics in explaining the impact of demographics on financial markets.     

Consumer reaction to product recalls: factors influencing product judgement and behavioural intentions

In order to evaluate the factors influencing consumers’ responses to product recalls, two surveys were conducted among Brazilian automobile owners and two regression models tested. Results indicated that (i) product judgement was significantly affected by corporate social responsibility (CSR), blame attributed to the company and whether or not consumers had a car made by the brand considered; and (ii) behavioural intentions were significantly affected by CSR, consumers’ involvement with the message, perceived danger, product judgement and whether or not consumers had a car made by the brand considered. Findings revealed, however, that CSR is a better predictor of the product judgement than of the behavioural intentions, in accordance with recent studies indicating that CSR affects consumer judgements and behaviour differently. Finally, these two models are discussed and compared with previous research.
