Does Financial Education Impact Financial Literacy and Financial Behavior, and If So, When?

In a meta-analysis of 126 impact evaluation studies, we find that financial education significantly impacts financial behavior and, to an even larger extent, financial literacy. These results also hold for the subsample of randomized experiments (RCTs). However, intervention impacts are highly heterogeneous: financial education is less effective for low-income clients as well as in low- and lower-middle–income ...

Consumption and Models of the World Economy

Estimating a Consumer Demand System of Energy, Mobility and Leisure: A Microdata Approach for Germany

Higher prices for energy goods like gas, electricity or fuel oil due to higher indirecttaxation amongst others may have serious welfare and distributional effects for households. Also, there is very little evidence of the labor market implications ...

The Effect of Peer Observation on Consumption Choices: Experimental Evidence

Further, we find that individual's consumption choice is influenced by the group choice controlling ...
