The evolution of markets and the revolution of industry : a quantitative model of England’s development, 1300-2000

This paper argues that an economy's transition from Malthusian stagnation to modern growth requires markets to reach a critical size, and competition to reach a critical level of intensity. By allowing an economy to produce a greater variety of goods, a larger market makes goods more substitutable, raising the price elasticity of demand, and lowering mark-ups. Firms must then become larger to break even, which facilitates amortizing the fixed costs of innovation. We demonstrate our theory in a dynamic general equilibrium model calibrated to England's long-run development and explore how various factors affect the timing of takeoff.European Community's Seventh Framework ProgramFinancial aid from the European Commission (EFIGE Grant 225343 and HI-POD Grant 225551), the Comunidad de Madrid (PROCIUDAD-CM), and the Spanish Ministry of Science (ECO2008-01300) is acknowledged

Bigger is better: Market size, demand elasticity and innovation

This paper proposes a novel mechanism whereby larger markets increase competition and facilitate process innovation. Larger markets, in the sense of more people or more open trade, support a larger variety of goods, resulting in a more crowded product space. This raises the price elasticity of demand and lowers mark-ups. Firms, therefore, become larger to break even. This facilitates process innovation as larger firms can amortize R&D costs over more goods. We demonstrate this mechanism in a standard model of process and product innovation. In doing so, we question some important results in the new trade and endogenous growth literatures.trade; population; price elasticity; competition; innovation; firm-size; scale effects; Dixit-Stiglitz; Hotelling

Market Size, Trade, and the Resistance to the Adoption of Better Technology

Why is the adoption of more productive technologies more fiercely resisted in some societies than in others? This paper examines the role of market size and free trade in determining whether firms or workers resist the adoption of more advanced technologies. It puts forth a model whereby the price elasticity of demand for each industry's product is an increasing function of the economy's population size. A more elastic demand lowers the resistance to technology adoption because the drop in the price of the industry's output that follows the adoption of a cost-saving technology is associated with a larger increase in industry's revenue. We demonstrate this mechanism numerically and provide empirical support for this theory.Technology Adoption, Resistance, Trade, Ideal Varieties

The Evolution of Markets and the Revolution of Industry: A Unified Theory of Growth

This paper puts forth a unified theory of growth that captures a number of relevant features of countries transitions from stagnant, predominantly rural economies to vibrant, industrialized economies that have been overlooked by the literature. In our theory, increasing variety of consumer goods and increasing firm size, which are the consequence of a gradual expansion in the market, sow the seeds for process innovation and an economy’s take-off. We demonstrate this mechanism in a dynamic general equilibrium model calibrated to England’s long-run development, and explore how various factors affected the timing of its take-off.Uni�ed Growth Theory, Industrial Revolution, Innovation, Competition, Market Revolution

Omentopexy for correction of right abomasal displacement: results in 135 cows

One hundred and thirty-five cows were surgically treated for correction of right displaced abomasum (RDA) using the right flank omentopexy technique. In 33 cows an abomasal dilatation was diagnosed. Abomasal volvulus was found in 99 animals and omaso-abomasal volvulus in three. In-hospital mortality was 15% (n = 20). None of the cows with abomaso-omasal torsion survived. Ninety-seven percent (n = 32) of the cows with abomasal dilatation and 84% (n = 83) of the cows with abomasal volvulus were discharged from the clinic. Six months after surgery, respectively 94% of the cows with abomasal dilatation had survived. This percentage fell to 88.5% after another half year. For cows with abomasal volvulus, these survival rates were 74% and 62%, respectively. Regardless of the type of abomasal dislocation, 77% of the total group of animals survived after six months and 66% after one year. Six months after surgery, good milk production was reported in 67% (n = 58) of the surviving cows; this figure rose to 91% of the surviving cows (n = 63) after 12 months
