1 The focus on TV news may be surprising, as investors are likely to derive their views and decisions from sources other than TV news. However, if the current study can confirm the impact of TV news on bond spreads, this could be important information for instance for central bank ...
The analytical strategy of this paper aims to estimate the effect of developmental declines on mothers’ cognitive stimulation. To do so, it uses two different strategies. In the first part of the analysis, I present the results from a two-way fixed effects (TWFE) estimator. In the second ...
Borrowing terminology from the program evaluation literature, I will interpret the coefficient that measures the sensitivity to rebates as an intent to treat estimator (Imbens and Angrist 1994), i.e., the average effect of the rebate on sales multiplied by the probability of taking advantage of ...
To answer this research question, we draw on both research in representation and psychology. Based on a large and diverse body of literature, we derive 25 different possible ways of asking people whether they feel represented. Following exposure to constructed representative claims by unelected repres...
Finally, the correct CRT responses made by participants were quantified, the median was estimated and the sample was divided into two subgroups. These responses were used as an estimator of the cognitive process followed by respondents [35,36] and system 1 was assigned to those who followed a ...
The inconclusive outcomes of the regression analysis in Eq. (3) could arise from various factors, including the utilization of the OLS estimator to explore the relationship between CSP and earnings yield, the selection of the CSP indicator, and the direct inclusion of the CSP indicator as a reg...
Even if this increased scrutiny does not reveal all the existing fraud, the Kol- mogorov axiom of conditional probability allows us to derive an upper-bound (and thereby conservative) estimate of the detection likelihood, which in turn provides us with a lower-bound estimate of the pervasiveness...
3 we derive estimates of F for the AOGCMs. In Sect. 4 we show that, if the AOGCMs are realistic, \mathrm {d}R/\mathrm {d}T evaluated from historical climate change by Eq. (3) may be an imprecise and biased estimate of the historical \alpha, owing to the statistical effects of ...
Finally, we use the ordinary least squares (OLS) method to estimate ββ, which is called the Fixed Effect Estimator, 𝛽̂𝐹𝐸β^FE. In our study case, the dependent variable is an ADL, represented by the CDR-based people density for a specific POI. Independent variables are ...
