In 1764, he also entered the public administration, where he distinguished for his reforming attitudes: in particular, he proposed the abolition of the exaction of taxes through intermediaries. After a documented
Bilance on the Commerce of the State of Milan, In 1769 Verri published notable work,
Elementi del Commercio ("Elements of Commerce"), inspired by a wide interpretation of liberalism in commerce. This was followed by the ''Meditazioni sull'economia politica'' ("Reflection's on Political Economy", 1771), the book contains 40 sections and when Verri's Meditiazioni first appeared was well received. Its success was considerable, in just one year, five different editions produced. According to
Schumpeter, Verri was one of the first economists to figure out a
balance of payments and
Schumpeter adds Verri is the most important pre-Smithian authority on Cheapness and Plenty. His work is clearly one of the many examples in the economic literature which during the quarter-century after 1750 marks the emergence of
political economy as a separate science. Pietro Verri provides the first systematic contribution stemming from the quarters of Lombard enlightenment in the field of
political economy. From the vantage point afforded by Verri's
political economy, we gain a wide view of significant elements and characteristic concepts of Lombard enlightenment during the latter half of the 18th century. Meditiazioni can be separated three different parts. The first, covering the first five sections, presents the general principles of the science by explaining economic development and growth, circulation, production, exchange, money, and prices in general terms. These general principles are supplemented and elucidated on money, industry, interest, and circulation and on population. Part II then applies these principles to a number of policy questions in
political economy: the distribution of
landed property, guilds and other forms of restrictive practices through privilege, price controls, controls over sales, sumptuary laws and some observations associated with population and agriculture. Part III presents the theory of finance while the last three sections act as a sort of summary of the policy implications of the material presented. First 5 editions of Meditiazioni do not contain any mathematical term, however, some footnotes added in the sixth edition in order to interpret Verri's economic thought into mathematical terms. The aim of political economy to increase national power, strength and happiness is achievable through an increased population, incentives to labor, increased production and an appropriate balance between it and consumption. Success in achieving this policy objective can be measured by at least three different means in the absence of reliable
national output data, as Verri indicates at various points in his treatise. These are the
balance of trade, which he regarded as an imperfect measure; the level of the rate of interest, which he saw as a better measure, and population size and characteristics, which he saw as the best measure because it could be most accurately measured.
Theory of prices According to Verri, the price of a commodity is directly related to "need" and inversely to plenty. By "need", Verri does not mean any indeterminate desire, but the effective demand of goods, i.e. the level of demand at which the expected utility of any good is higher than the cost individual are ready to pay in order to acquire it . Verri stresses consumer sovereignty, by arguing that
demand regulates
supply and not the contrary. As to plenty, it basically depends on the market form: it is larger when the market approximates to
perfect competition.
An equilibrium between production and consumption The problem of equilibrium between production ("reproduction" in Verri's terms) and consumption is analyzed examining two opposed cases of disequilibrium. Verri's contribution is strictly connected here to the basic theoretical assumptions of his theory of action. It is also very original in its issues. The first case takes place when national consumption is greater than production and the balance of commerce is unfavorable. Unlike Hume, Verri pays no attention to deflux of money and to the ensuing
deflation. His interest is devoted to real re-equilibrating mechanisms. There are two possible solutions to disequilibrium: the first one is negative and consists of factor mobility (emigration of a part of the laboring force). When the other solution prevails, new productive branches are created in the country: these new industries compete in quality and price with those located abroad, toward which the demand for imported goods was addressed. This process of import substitution re-equilibrates the balance of commerce. Welfare grows in the country with the increasing size of the internal market. The role of ideas is central to this picture: a class of individuals understands the existence of
national demand for certain goods and produces it at better conditions than foreign competitors. In the second case, consumption is smaller than production, and the balance of commerce is favorable. As a matter of fact, Verri engages himself in demonstrating that a favorable balance of commerce is possible at certain conditions, that inflation is not a necessary outcome of it, and finally that a growth of the real side of the economy is consistent with it. Inflation takes place only if the extra monetary demand clashes with rigidities on the supply side (in this case, money "stops" in the hands of an unmodified number of sellers). However, this case is not very likely in a "polite" nation. Verri describes here a sort of
Hume-
Cantillon transmission mechanism without inflation. Additional money, passing from hand to hand, incites industry and puts unemployed factors at work. The Verrian self-sustained mechanism of growth based on increasing income, new needs, and new productions, is the result of this first impulse. Here too, the entrepreneurial spirit plays an essential part. == Philosophical work ==
