- Thanh Le & Uwe CantneR & Jean-Luc GaffaRd & Lionel Nesta (2009): A dual economy model of endogenous growth with R&D and market structure
This paper develops a dual economy endogenous growth model to consider the effects of market structure and innovation on the rate of growth of an economy. ... It is shown that growth is increasing in the market power that firms in the innovative goods sector obtain but decreasing in the equilibrium number of firms in the traditional goods sector.
RePEc:spr:sprchp:978-3-540-93777-7_7 Save to MyIDEAS - Nuno PedRo Gonçalves Palma (2004): Innovation, Market Structure and Economic Growth
This paper presents a dynamic partial equilibrium model that endogenizes firms' investment decision on innovation: product innovation causes horizontal expansion growth, and process innovation causes vertical expansion growth. Market structure in different markets emerges as a consequence of different investment on innovation opportunities. Main variables that constrain this structure in a given market are the rate of scientific (basic) discoveries that permit innovation productivity, and the degree of substitution between varieties, together with the possible existence of scope economies.

We present a discrete-time version of an otherwise standard Schumpeterian growth model. ... Second, R&D firms sometimes innovate simultaneously. The resulting market conduct is critical. ... Surprisingly, the industry demand for R&D inputs does not depend on the number of firms in the R&D sector if Bertrand competition ensues following ties. ... Under collusion, production is always at the monopoly level, but there is faster growth.
RePEc:ecm:feam04:490 Save to MyIDEAS - Chu, Angus C. & FuRukawa, Yuichi (2012): Patents versus R&D subsidies in a Schumpeterian growth model with endogenous market structure
In this note, we explore the different implications of patent breadth and R&D subsidies on economic growth and endogenous market structure in a Schumpeterian growth model. We find that these two policy instruments have the same positive effect on economic growth when the model exhibits counterfactual scale effects under an exogenous number of firms. However, when the model becomes scale-invariant under an endogenous number of �firms, R&D subsidies increase economic growth but decrease the number of firms, whereas patent breadth expands the number of firms but reduces economic growth. Therefore, R&D subsidy is perhaps a more suitable policy instrument than patent breadth for the purpose of stimulating economic growth.

This letter explores the different implications of patent breadth and R&D subsidies on economic growth and endogenous market structure in a Schumpeterian model. We find that the two policy instruments have the same positive effect on economic growth when the model exhibits scale effects under a fixed number of firms. When the model becomes scale-invariant under an endogenous number of firms, patent breadth increases economic growth but decreases the number of firms, whereas R&D subsidies increase the number of firms but decrease economic growth.
RePEc:pra:mprapa:40469 Save to MyIDEAS - Daniel BRou & Michele Ruta (2007): Rent Seeking, Market Structure and Growth
In the economic market, firms compete for market share through cost reducing technological innovation. Market structure plays an important role in this economy because competition drives firms to invest more in innovation resulting in higher growth. Rent-seeking affects economic growth in two important ways. ... The former has a negative effect on growth while the latter effect is ambiguous, depending on whether rent seeking induces entry or exit. This market structure effect depends on a combination of political and economic factors that the theory highlights.

We study how alternative market structures influence market supply and R&D investment decisions of firms operating in dynamic imperfectly competitive environments. Firms can reduce their future production cost through R&D investment today, which is the engine of endogenous industry growth. ... These ingredients are a static market externality, stemming from the standard oligopolistic Cournot competition, a dynamic externality that arises due to knowledge spillovers, and a dynamic market externality that comes from the interaction of knowledge spillovers with future market oligopolistic competition that firms internalize while making decisions. We isolate the impact of each strategic ingredient by comparing four alternative market structures.
RePEc:ucy:cypeua:8-2003 Save to MyIDEAS - Chien-Yu Huang & Juin-Jen Chang & Lei Ji (2013): Cash-In-Advance Constraints in a Schumpeterian Growth Model with an Endogenous Market Structure
This paper explores the macro effects of monetary policy in a Schumpeterian growth model with an endogenous market structure and distinct cash-in-advance (CIA) constraints on consumption, production, and two distinct types of R&D investment - in-house R&D and entry investment. ... Specically, if in-house R&D or quality improvement-type R&D (entry investment or variety expansion-type R&D) is subject to the CIA constraint, raising the nominal interest rate decreases (increases) the firm's market size and economic growth. If either production or consumption is subject to the CIA constraint, growth is immune from money, while the market structure and employment are responsive.
