Money donation and time donation, as charitable donations from individuals to organizations, are two forms of prosocial behavior that have been increasingly studied in recent years. Despite the vast amount of research about money and/or time donation, however, only limited work has been done on reviewing the research on these two forms of charitable donations as comparable or parallel entities. In this paper, we seek to help fill this gap by reviewing the existing research. We applied the backwards and forwards snowballing technique to arrive at a review sample of 39 experimental papers published in 2000–2020 that have compared money and time donation, or at least analyzed them as two parallel entities. We examine the issues that are predominantly considered in these experimental papers and summarize the general directions of their findings. We also point out certain gaps in the existing literature and posit some potentially fruitful directions for future experimental research regarding money and time donation.

The major objective of this research is to test if two types of information overload are different: Information overload from searching for the information someone needs to search, and information overload from following all the information someone needs to follow. These two types of information overload may be labelled information search overload and information follow overload, corresponding to the concepts of information search and information follow. Using the data of a survey from a sample of about 1600 respondents across 50 states in the United States, the research identified 2 items corresponding to information search overload and information follow overload, and ran analyses including correlation and logistic regression with the 2 items separately as the dependent variables, and with some other items about consumers’ activities involving information as independent variables. Results of the various analyses suggest that information search overload and information follow overload are different, especially in terms of how they associate with different variables of consumer activities involving information, therefore indicate as a preliminary research that we may separate the two types of information overload in our future research.
