Credibility of empirical research is being increasingly questioned due to the concern over the misuse of data analysis for a statistically significant impact where the expected effect does not exist. Technically, this is often called “p-hacking.” However, for most researchers, this is more like a star war.
Wages are highly sensitive to the employee's majors. Ranking by lifetime salary, economics is usually among the best performance majors. Is there a real causal relationship here, or just a result of self-selection?
As we welcome the new age of renewable energy, we usually focus more on reforming the economic structure but, intentionally or unintentionally, ignore the political institution. A recent empirical study sheds some light on the crucial role of democratic institutions in promoting renewable energy consumption.
When oil prices increase, retail gasoline prices skyrocket. When oil prices decrease, gasoline prices fall like a feather. What explains this asymmetric response?
As people are more likely to borrow when they are young but save when they are middle-aged, a high middle to young ratio implies an excess demand for saving, surging the stock prices. So if we can forecast demographic changes, we can forecast stock returns, too.
There is empirical evidence of the positive effect of democracy on economic growth, measured in GDP per capita. However, this effect cannot be detected for countries in the Sub-Saharan Africa area. The cause of this can be found in child mortality rates.
Is it worth switching to renewable energy or we have to sacrifice economic growth for green ideas? New research reveals that it may hurt at the beginning, but later pays off.
We all know public debt matters. Yet, no one knows how it exactly matters to economic growth. Does public debt cause growth? Is there a tipping point? Does the impact of debt on growth homogeneous for all countries?
