The theory of effective protection a critique

Summary A linear two-by-two general equilibrium model of international trade has been developed with international mobility of capital goods and capital funds. By means of this model the consequences of imposing an ad valorem tariff on imported inputs and imported consumption have been investigated. Special attention has been paid to the consequences of a differentiated tariff structure for total imports.The analysis leads to the conclusion that in the present model a unique relation between the differentiated tariff structure and the effective protective rate does not exist.In many respects this article draws heavily upon my doctoral dissertation:Heterogeen kapitaal en internationale handel, mimeographed, Tilburg, 1973     

Money creation and economic activity

Summary In the Netherlands not much attention is paid to money supply figures as an indicator of actual monetary conditions. This can be partly explained by the publication lag and the continuous revisions of seasonally adjusted data. However, the information that can be derived from money supply figures is limited because of temporary disturbances originating from the foreign exchange market. In this paper a correction method for these temporary disturbances is proposed. Money supply figures show a much closer link to real economic activity when corrected in this way.A different version of this essay with less emphasis on Holland but more information about other West-European countries has been published as chapter II Watching the money supply in: Eduard J. Bomhoff,Monetary Uncertainty, Amsterdam and New York, 1983. We gratefully acknowledge the able research assistance of Isolde B.
