Institutions like the Amsterdam stock exchange, the Bank of Amsterdam, and the merchant bankers helped to mediate this investment.
In the course of time the invested capital stock generated its own income stream that (because of the high propensity to save of the Dutch capitalists) caused the capital stock to assume enormous proportions.
Holland's contribution was the norm from which the contributions of other provinces were derived.
After some changes the quota were fixed in 1616 as follows (to remain unchanged till 1792): Friesland one-fifth of Holland's share; Zeeland (after some diligent bargaining) 16 percent; Utrecht and Groningen one-tenth each; Gelderland 9.6 percent; Overijssel 6.1 percent; and Drenthe (though not represented in the States-General) 1 percent.
Where in other instances the modern fiscal system resulted from, and was made subservient to, the interests of a centralizing monarchical state, in the Dutch instance the emerging fiscal system was the basis of, and was mobilized in the interests of the defense of, a stubbornly decentralised political entity.To that end it was necessary to put in place a number of fiscal reforms that would ensure that the public debt could be adequately serviced (thereby increasing the creditworthiness of his government).In 1542 the president of the Habsburg Council of State, Lodewijk van Schoor, proposed the levy of a number of taxes throughout the Habsburg Netherlands: a Tenth Penny (10 percent tax) on the income from real property and private loans, and excise taxes on beer, wine, and woollen cloth.Ironically, the Habsburg rulers themselves pushed through the fiscal reforms that gave the rebellious provinces the wherewithal to resist the power of the sovereign.Emperor Charles V needed to increase the borrowing capacity of his government to finance his many military adventures.
