Corporate taxes, growth and welfare in a Schumpeterian economy
(Journal of Economic Theory, 2007-11-01) Peretto, PF
I take a new look at the long-run implications of taxation through the lens of modern Schumpeterian growth theory. I focus on the latest vintage of models that sterilize the scale effect through a process of product proliferation that fragments the aggregate market into submarkets whose size does not increase with the size of the workforce. I show that the following interventions raise welfare: (a) granting full expensibility of R&D to incorporated firms; (b) eliminating the corporate income tax and/or the capital gains tax; (c) reducing taxes on labor and/or consumption. What makes these results remarkable is that in all three cases the endogenous increase in the tax on dividends necessary to balance the budget has a positive effect on growth. A general implication of my analysis is that corporate taxation plays a special role in Schumpeterian economies and provides novel insights on how to design welfare-enhancing tax reforms. © 2007 Elsevier Inc.

Cost reduction, entry, and the interdependence of market structure and economic growth.
(1999) Peretto, PF
I study the joint determination of market structure and growth in an oligopolistic economy. Firms run in-house R&D programs to produce over time a continuous flow of cost-reducing innovations. In symmetric equilibrium, the relation between market structure and growth has two aspects. First, a larger number of firms induces fragmentation of the market and dispersion of R&D resources. This prevents exploitation of scale economies internal to the firm and slows down growth. Second, the number of firms changes with market and technology conditions and is endogenous. In particular, R&D spending is a fixed cost and there is a negative feed-back of the rate of growth on the number of firms. The explicit consideration of the interdependence of market structure and growth identifies a fundamental trade-off between growth and variety that produces interesting results. For example, the scale effect is bounded from above and converges to zero when the number of firms is large. Moreover, the market grows too little and supplies too much variety. The inefficiency is not due to technological externalities but to oligopolistic pricing and the interaction between R&D and entry decisions. [ABSTRACT FROM AUTHOR]

Endogenous Growth and Property Rights over Renewable Resources
(2015) Suphaphiphat, N; Peretto, PF; Valente, S
We study how different regimes of access rights to renewable natural resources – namely open access versus full property rights – affect sustainability, growth and welfare in the context of modern endogenous growth theory. Resource exhaustion may occur under both regimes but is more likely to arise under open access. Moreover, under full property rights, positive resource rents increase expenditures on manufacturing goods and temporarily accelerate productivity growth, but also yield a higher resource price at least in the short-to-medium run. We characterize analytically and quantitatively the model׳s dynamics to assess the welfare implications of differences in property rights enforcement.

Endogenous market structure and the growth and welfare effects of economic integration.
(2003) Peretto, PF
This paper studies the growth and welfare effects of integration in a world economy populated by global oligopolists. In economies that move from autarky to trade, growth and welfare rise because exit of domestic firms is more than compensated by entry of foreign firms so that integration generates a larger, more competitive market where firms have access to a larger body of technological spillovers that support faster growth. The effects of a gradual reduction of tariffs are different because economies start out from a situation where all firms already serve all markets. In this case, the global number of firms falls so that the variety of consumption goods and the diversity of innovation paths fall. The surviving firms, on the other hand, are larger and exploit static and dynamic economies of scale to a larger degree. These homogenization and rationalization effects work in opposite directions. Under plausible conditions, the rationalization effect dominates and growth and welfare rise.

Financial Markets, Industry Dynamics, and Growth
(Economic Research Initiatives at Duke (ERID), 2014-08-27) Iacopetta, M; Minetti, R; Peretto, PF
We study the impact of corporate governance frictions in an economy where growth is driven both by the foundation of new firms and by the in-house investment of incumbent firms. Firms' managers engage in tunneling and empire building activities. Active shareholders monitor managers, but can shirk on their monitoring, to the detriment of minority (passive) shareholders. The analysis reveals that these conflicts among firms' stakeholders inhibit the entry of new firms, thereby increasing market concentration. Despite depressing investment returns in the short run, the frictions can however lead incumbents to invest more aggressively in the long run to exploit the concentrated market structure. By means of quantitative analysis, we characterize conditions under which corporate governance reforms boost or reduce welfare.

From Smith to Schumpeter: A theory of take-off and convergence to sustained growth
(European Economic Review, 2015-08-01) Peretto, PF
© 2015 Elsevier B.V.This paper proposes a theory of the emergence of modern Schumpeterian growth that focuses on the within-industry forces that regulate the response of firms and entrepreneurs to Smithian market expansion and thus identifies an amplification mechanism that the literature has neglected. Because it solves the model in closed-form, the paper provides analytical insight on the forces that drive the economy's phase transition and the associated qualitative transformation of industrial activity. The resulting S-shaped path of GDP per capita replicates the key feature of the data: an accelerating phase followed by a deceleration with convergence to a stationary growth rate. The model also yields predictions for grand ratios like consumption/GDP, profits/GDP, and the distribution of income across factors of production.

Growth on a Finite Planet: Resources, Technology and Population in the Long Run
(CER-ETH Working Paper, 2011-06-30) Peretto, PF; Valente, S
We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. There exists a pseudo-Malthusian equilibrium in which population is constant and income grows exponentially: the equilibrium population level is determined by resource scarcity but is independent of technology. The stability properties are driven by (i) the income reaction to increased resource scarcity and (ii) the fertility response to income dynamics. If labor and resources are substitutes in production, income and fertility dynamics are self-balancing and the pseudo-Malthusian equilibrium is the global attractor of the system. If labor and resources are complements, income and fertility dynamics are self-reinforcing and drive the economy towards either demographic explosion or human extinction. Introducing a minimum resource requirement, we obtain a second steady state implying constant population even under complementarity. The standard result of exponential population growth appears as a rather special case of our model.
