… not the ultimate causes.

Globalisation and History
• Three Great Phases
• 1 Late nineteenth century
• 2 The Post-WWII era
• 3 The Current Phase
![Page 10: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/10.jpg)
History and Theory
• From nineteenth century globalization yo the Hecksher-Ohlin model
• The empirical success of Hecksher-Ohlin
• The O’Rourke-Williamson anaysis
![Page 11: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/11.jpg)
History and Theory continued
• Balassa’s evidence
• The Intra-Industry Trade debate
• The rise of the Dixit-Stiglitz-Krugman model
![Page 12: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/12.jpg)
History and Theory continued
• So what’s going on now?

Quality and Trade : the new literature
![Page 14: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/14.jpg)
Motivation
• 1 Firms’ concerns
• 2 Empirical patterns in new firm level data sets
![Page 15: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/15.jpg)

u c = ‘productivity’
u = ‘quality’
Capability is a pair (c, u) for each technical trajectory (submarket)

Key feature:
The consumers choose products offering the best u/p
Implication: if u>v, the market share of a firm offering u cannot be eroded to zero by any number of firms offering v

Proposition 1
- given any configuration of capabilities
(c1,u1), (c2,u2) . . (cn,un)
there is a lower bound in (c,u) space below which a firm cannot achieve positive sales at equilibrium
(ex. Cournot equilibrium)

Fixed /Sunk costs
• Iso-elastic response of quality(beta)
• Isoelastic response of labour productivity (gamma)
• Unit variable cost = labour cost + materials cost
![Page 21: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/21.jpg)
Proposition 2
Suppose one element in building capability is the expenditure of fixed outlays (“sunk costs”)
- Then competition in ‘capability building’ will lead to a bound on the number of firms ‘in the window’.

So what’s new?
• The model has been chosen so that prices and qualities, and therefore productivity and quality enter in a completely symmetric fashion
• The key point is that unit materials cost sets a floor to price, thus limiting the degree to which changes in wages and productivity can offset changes in quality
![Page 28: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/28.jpg)
Quality vs. productivity
• Once raw materials at international prices are an input….
• Wage adjustment can rescue poor productivity…
• But not poor quality

A Digression ….
• An extension of the model adds a second parameter (horizontal differentiation)
• This can be further generalized to “linkages between sub-markets”
• This extension is important in providing an explanation for cross-industry differences in market structure

A Multi-Country Model
• m industries ; Cobb-Douglas consumers
• r of these are commodity type, many firms
• m-r have n firms in each of countries A,B
• Country C supplies raw material
• Labour supply same in all
• Capability of B firms < A firms

Modelling Pre-Globalisation
• The aim is to exclude competition in “quality” goods, while allowing A and B to source materials from C.
• Two routes:
• (i) Partition country C
• (ii) Unify C but inhabitants are insensitive to quality differences
![Page 35: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/35.jpg)
Three Phases
• Phase I: Impact phase…Capabilities given
• Phase II: Transfer phase
• Phase III: Re-investment (escalation) phase
![Page 36: Competing in Capabilities. …some stories about growth: 1.All you need is Capital.](https://reader035.fdocuments.net/reader035/viewer/2022070412/56649d565503460f94a33d8f/html5/thumbnails/36.jpg)
Phase I : Impact
• There are three regimes, depending on the size of the gap in capability
• Regime I….gap ~ 0
• Regime II…..moderate gap
• Regime III….wide gap

Main substantive argument
• The case for globalisation should rest primarily on the transfer and growth of capabilities it induces
• A fundamental set of mechanisms are driven by the coexistence of high capabilities and low wages
• These mechanisms include, inter alia, • ---self help driven by new incentives• ---Transfers via FDI/ Supply chains, etc.
