Purpose of the
*
study
Find out what the economic effects of
unions and collective bargaining are,
when unions exist
(this is different than:
“what happens if unions are introduced?)

Unions and Collective Bargaining: Economic Effects in a Global Environment
Does economic performance deteriorate
in more unionized economies
or when bargaining becomes more centralized?

What are “unions”?
What they do and how they operate?
With whom (what type of government)?
In what kind of economy?
The way economists have addressed these issues
results many combinations (how many?)
What is “Unions”?
• Union density (% of workers unionized)
• Union coverage (% of workers whose
wages are affected by collective
agreements)
• Other (e.g. closed shop, index of power of
exposed sector unions etc)
There is weak relationship between the % of workers
(a) who are union members and
(b) whose wages are affected by collective bargaining

But
Does the Economy Matter?
•
•
•
•
Closed economy?
Open economy?
Competitive economy?
Monopolistic economy?
So, what are the effects of:
•
•
•
•
3 dimensions of “unions”
7 types of coordination
2 types of (polar) governments
4 types of (stylized) economies
OVERALL 168 combinations

Of course, on the labor market!

•
Aggregate real wage flexibility (to U)
Hysteresis (persistence of unemployment)
Adjustment speed (to real wage shocks)
Search effectiveness (Vacancies to U)
So, which of the 30 or so effects
on micro and macro indicators
comes from 168 combinations of
unions, employers, governments
and types of economies?
(Semantics, selectivity and biases
are important)
Does economic performance deteriorate
in more unionized economies
or when bargaining becomes more centralized?

Table 2.2: Relationship between Core Labor Standards and International Trade:
Evidence from OECD and Non-OECD Countries
Trade indicator
Trade performance.
Revealed comparative advantage.
Definition
Growth in the share of a county’s exports
in total world trade (measured as total
export, raw material export, or
manufacturing export), 1980-1990.
Index for comparative advantage
calculated for 71 sectors on the basis of
foreign trade performance for these
sectors.
Trade prices
US import prices of textiles from a group
of other OECD and non-OECD countries.
Trade liberalization
The change in tariffs and quantitative trade
restrictions, 1980-1990.
OECD investment outflow to non-OECD
countries, 1975-1993.
Foreign direct investment (FDI)
Export-processing zones (EPZ)
Firms in an area that offers privileges with
regard to government policies.
Result
No correlation
No effect on the pattern of revealed
comparative advantage. Comparative
advantage is, by and large, determined by
the abundance of factors of production and
technology.
No effect on border prices in the US for
similar, imported textiles from different
countries. Likewise, US import of textiles
from “high-standard” OECD countries has
not been “crowded out” by imports from
“low-standard” non-OECD countries.
Positive correlation with the trade
liberalization.
Low labor standards not an important
factor for investment decisions in OECD
firms.
In only 6 countries out of the 73 that have
established EPZs, evidence exists of
deliberate government attempts to restrict
freedom to associate and the right to
bargaining collectively. The countries are
Bangladesh, Jamaica, Sri Lanka, Pakistan,
Panama, and Turkey.

Summary Effects
(Macroeconomic)
• More labor market coordination seems to be better
for low unemployment, earnings inequality, fewer
strikes than semi – and uncoordinated LM
• Coordinated and uncoordinated LM fare equally
in terms of productivity growth and wage
flexibility
• No difference in inflation and employment rates
• Differences reduced/very weak in the long run (as
countries adapt one way or another)
Summary Effects
(Microeconomic)
• Unions create differentials in favor of their
members (but is this always bad?)
• The union effects on the performance of firms
vary and are often ambiguous
If competitive wages in the absence of unions = 100,
what does it mean if RED wages are 20% more than BLUE wages ?
