Money supply endogeneity and bank stock returns

This article presents results of tests on two related hypotheses on money supply. The first relates to an unresolved issue of money endogeneity while the second centres on the yet-explored relationship between money supply and bank stock returns if money is found to be endogenous. Our results, using long-horizon data of Group of Seven (G-7) economies, supports causality in money supply as running from bank lending to bank deposits, a result that is predicted by the post-Keynesian money supply endogeneity (bank-credit-driven) theory. Thus, the result is not consistent with exogeneity proposition. A new evidence of positive relationship between endogenous money supply and aggregate bank stock return is statistically significant on this hitherto unexplored topic. These findings are consistent with the post-Keynesian money supply theory and the dividend valuation theory, which predicts money supply changes to induce changes in bank earnings, so bank share prices change.money supply endogeneity, bank stock returns, credit market, liquidity provision, post-Keynesian theory, dividend valuation theory, G-7 countries,
