I'm writing an economics thesis and I've found many econometric papers in which I found regression tables without the p-value. They only show the coefficient of the independent variable and its t-value, like in the example image.
My econometrics knowledge is very elementary, but I thought that the most important thing to evaluate the significance of a variable was the p-value. Searching on the web, I've found that sometimes $t-value>2$ is considered as a good value for significance. Is that right? Can I say that when $t-value>2$ the coefficient is statistically significant?
Edit: after Rob's suggestion, here's a link to the paper
