Impacts of technology readiness on emotions and cognition in Brazil

This study proposes and tests an extended model for consumer adoption of high technology products in a Latin American country (Brazil) by integrating concepts present in the consumer behavior literature: the Consumer Acceptance of Technology model (Kulviwat et al., 2007) and the technology readiness construct (Parasuraman, 2000). The proposed model considers the relationships between cognitive and affective constructs with technology readiness. By means of structural equation modeling conducted on a sample of 435 young consumers, the results indicate significant relationships between the constructs assessed, showing that consumers' cognitive and affective evaluations of new technologies are significantly influenced by their technology readiness. The effects of technology readiness over affective assessments were greater than those relative to cognitive evaluations regarding high-tech innovations. Nonetheless, the results may reflect specific characteristics of Brazilian (and other Latin American) consumers, who are usually more emotive than those of more rational cultures.     

The effect of social security,health, demography and technology on retirement

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a lifecycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy – which became much more generous – and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement.     

Selling price,financing premiums,and days on the market

Home buyers face the task of trading off selling price and the time required to sell a property. One factor that may affect this decision is the presence of financing premiums. The effects of financing premiums on the time a single-family home remains on the market is examined in this paper. The question is to what extent home sellers are willing to compromise on financing premiums and make concessions to buyers in order to sell their properties more quickly.The study uses a sample of single-family residential homes sold with assumption financing and new conventional financing. The sample covers segments of time when interest rates were relatively low and stable (1975–1976) and when rates were much higher on average and more volatile (1980).The results show that financing premiums were present in selling prices of assumption-financed home sales during the 1975–1976 period and that sellers were able to capture a premium and maintain the same average time on the market as properties with other types of financing. During a period of unfavorable market conditions, such as 1980, the results indicate that home sellers with assumption financing conceded or negotiated away any premium in order to significantly decrease the number of days their properties stayed on the market for sale.     

Conditional beta pricing models: A nonparametric approach

We propose a two-stage procedure to estimate conditional beta pricing models that allows for flexibility in the dynamics of asset betas and market prices of risk (MPR). First, conditional betas are estimated nonparametrically for each asset and period using the time-series of previous data. Then, time-varying MPR are estimated from the cross-section of returns and betas. We prove the consistency and asymptotic normality of the estimators. We also perform Monte Carlo simulations for the conditional version of the three-factor model of Fama and French (1993) and show that nonparametrically estimated betas outperform rolling betas under different specifications of beta dynamics. Using return data on the 25 size and book-to-market sorted portfolios, we find that the nonparametric procedure produces a better fit of the three-factor model to the data, less biased estimates of MPR and lower pricing errors than the Fama–MacBeth procedure with betas estimated under several alternative parametric specifications.     

I do not own a car any more: An analysis of possessions’ disposal and changes in consumers’ identities

This research aims to understand the process of cars' disposal, its context, its influences and its impacts on the meanings for consumers and their identities, as well as the new behaviours of these consumers when living without their car(s). We conducted, analysed and interpreted 20 in‐depth interviews with consumers that had previously owned at least one car and had no financial reasons for disposing of their car(s), but had decided to do it, and started to live without them, adopting alternative methods of transportation. Our findings show that these consumers faced a complicated process regarding the disposal of their car(s) but, due to the changes in their circumstances, they re‐signified relevant concepts that were connected to the ownership of a car: Their perception of freedom, comfort, safety and status changed during and after the disposal of their car(s). We also noticed that there were implications in terms of changes in their attitudes and behaviour as both citizens and consumers. As a contribution to the literature, our findings indicate that the re‐signifying of concepts related to possession of the object as well as changes in attitudes and behaviours that consumers undergo in the postdisposal stage, must be included in the model proposed for evaluating consumer behaviour in product disposal.     

Capital asset pricing model in Portugal: Evidence from fractal regressions

We examine risk profiles of the Portuguese stock market index component stocks using a novel approach to the classical capital asset pricing model (CAPM). Specifically, we estimate the CAPM via fractal regressions that allow studying the marginal effects at selected scales. In this way, we can reveal whether the risk is perceived differently by market participants with different investment horizons. Apart from the analysis itself, we provide new statistical insights into the issue of separating and comparing the scale-specific effects with statistical validity. We find several stocks deviating from an expected risk perception homogeneity across investment horizons. This is true for both analysed periods, i.e. before and after the global financial crisis. There are also several stocks that changed their relationship to the market portfolio in between, which has strong implications for possible portfolio construction. The proposed methodology is not limited to financial topics but can be used in any discipline where the scale-specific marginal effects might be of interest.     

Political markets? Politics and economics in the emergence of markets for biodiversity offsets

This paper analyses the relationship between politics and performativity of economics in the emergence of markets for biodiversity offsets. While the role of economics in constructing markets has been demonstrated by sociology and social studies of science, it has also become apparent that politics plays an important role in the material outcome of economic experiments. Two case studies of the creation of markets for biodiversity offsets are analysed, in the United States and England. The findings suggest that the creation of both markets is rooted in the language, concepts and models of economics. Politics, on the other hand, functions as a mediator of the material expression of those models. Through this mediation effect, similar economic models are performed differently, resulting in a variety of markets. This suggests that the material outcomes of processes of market creation are not defined at the outset, but can be influenced by political processes.
