Question

How is economics related with political science and statistics?

Answer 1

Political science: politics is very intertwined with the economy.  Politicians decide how to regulate the economy, how much and what to tax, create incentives to do positive things and disincentives to avoid negative things, which actions to take in a recession, what to subsidize, how to deal with the tradeoff between equity and efficiency, etc.  Voters often vote based on the economy.

Statistics: the study of empirical economics would be impossible without stats.  Statistics measure important indicators such as GDP, unemployment, inflation, savings rate, etc.  Statistical methods are also used to make economic forecasts.

Answer 2

economics is a science of means.  political science is a science of ends.

for example.  

the United States was formed as an independent nation based on the declaration of independence.  this was a political goal; a political end.  to achieve independence and self sufficiency Hamilton and Madison worked to develop an economic system that would accomplish the political goal of independence.  It was called protectionism or protected market economics (the American School).

The tariff act of 1789, the very first act of congress signed by President Washington on July 4 was called the "second declaration of independence" because it was the economic means to achieve a self sufficient and independent nation.

statistics is mostly what is taught in economics classes.  charts, graphs, and past economic data are taught, but statistics are simply facts and are not reasoned.

political economy, or political science and economic science, are reasoned social sciences.
