The reaction of stock returns to unexpected increases in the federal funds rate target

This paper analyzes the impact of an unexpected increase in the federal funds rate target on stock returns. The main innovation is the use of a measure of monetary policy shocks based on the ACH-VAR (autoregressive conditional hazard VAR) model for the federal funds rate target. This model allows the analysis of two sources of an unexpected increase in the Fed target. This unexpected increase in the Fed target can be due to an unexpected increase in the federal funds rate target when it is expected to remain constant, or it can be due to an expected decrease in the federal funds rate target that fails to occur. These two events in the ACH-VAR model give rise to completely different information on the expected future federal funds rate. We examine the responses of stock returns for both S&P 500 stock returns and stock returns of portfolio sizes. We find that stock returns are more responsive to unanticipated increases in the federal funds rate than they are to unrealized expectations of a decrease in the federal funds rate. Our results also indicate that the firms with larger capitalization respond less to the two unanticipated monetary policy shocks.

Comparison of the occupational safety applications in marble quarries of Carrara (Italy) and Iscehisar (Turkey) by using Elmeri method

In this paper, a brief summary is given about marble quarries in Carrara (Italy) and Iscehisar (Turkey), the Elmeri method is introduced, work accidents that can happen in marble quarries and their causes besides work safety behaviours in fields are explained, and the Elmeri monitoring method is applied and analysed. For this reason, marble quarries are divided into seven in terms of working conditions and active six quarries both in Carrara and Iscehisar areas, and work safety behaviours are analysed. Analysis process is based on True–False method; there are 18 items in total under six main topics; three items on each topic. The safety index for each section and the main topics are also calculated. According to the calculated safety indexes, Carrara area marble quarries (65.08%) are safer than Iscehisar area marble quarries (46.01%).

The Role of the Beneficiary in Willingness to Pay for Socially Responsible Products: A Meta-analysis

Many companies have made significant investments in socially responsible production practices for their products. Environmentally safe cleaning products, fair trade coffee, and sustainable seafood are just a few examples. In this paper, we conduct a meta-analysis of over 80 published and unpublished research papers across a large number of product categories to better understand differences in willingness to pay (WTP) for socially responsible products. In particular, we are interested in whether the beneficiary of the social responsibility program—humans, animals, or the environment—affects WTP. We use two dependent variables: the percentage premium people are willing to pay and the proportion of respondents who are willing to pay a positive premium. We find that the mean percentage premium is 16.8 percent and that, on average, 60 percent of respondents are willing to pay a positive premium. Importantly, across both dependent measures, we find that WTP is greater for products where the socially responsible element benefits humans (e.g., labor practices) compared to those that benefit the environment. Implications for retailers, manufacturers, and future research are discussed.     

The role of emotions in shaping purchase intentions for innovations using emerging technologies: A scenario‐based investigation in the context of nanotechnology

Although emotions may not play a major role as antecedents of consumers′ innovation acceptance, this study proposes that attitude formation works differently in the context of emerging technologies because of their high levels of uncertainty. To investigate the role of emotions in shaping intentions to adopt innovations using emerging technologies, the conceptual model developed in this study integrates cognitive (risks and benefits) and emotional (optimism and worry) elements. A scenario‐based study employing 731 participants tests the model across three nanotechnology‐based product innovations that differ in terms of product category risk. The results of a mediated moderation model show that emotions do play a key mediating role in explaining purchase intentions. Although the study supports the conceptual model regardless of the level of product‐related risk, it finds risk‐related differences in the strength and level of the mediational links. By unveiling the role of emotions in emerging technology contexts, this study has important implications not only for innovation management but also for regulating institutions and public policymakers.
