Retail payments: New contributions, empirical results, and unanswered questions

We offer a selected survey of retail payments and suggest areas where additional research would prove useful. After summarizing eight papers presented at a recent Norges Bank (Central Bank of Norway) payment conference and published in this volume, we show how they, and many of the other papers presented there, have contributed to the payments literature. We also illustrate how institutional and other differences across countries led to different payment arrangements historically which now, due to technological innovation affecting bank costs, have made payment arrangements across countries more homogeneous.
