Since I shall be indicating my disagreement with some of the points made by Professor Israel Kirzner, let me stress that I am in complete sympathy with his point of departure, namely, the emphasis on the dispersion of information among economic decision-making units (called by him, "Hayek's knowledge problem") and the consequent problem of transmission of information among those units.
Much of my own research work since the 1950s has been focused on issued in welfare economics viewed from an informational perspective. The ideas of Hayek (whose classes at the London School of Economics I attended during the academic year 1938-39) have played a major role in influencing my thinking and have been so acknowledged.
