Finance,investment and innovation: A theoretical and empirical comparative analysis

The paper compares the relative efficiency of country models in the relationship between finance and investments. Results, confirmed under three different panel data estimates (Arellano-Bond GMM method, random and fixed effect estimates) suggest that: i) the UK thick market reduces informational asymmetries for large firms and for those firms providing good signals to shareholders; ii) the Japanese vertical (between firms and banks) integration and horizontal (among firms) integration almost eliminates financial constraints (the horizontal integration effect) and equates agency costs across firms (the vertical integration effect). These results are consistent with the short-termist hypothesis which assumes that the Japanese economic system can process information more efficiently reducing managerial myopic behaviour and thereby determining positive effects on long term growth.
