THE SILENT REVOLUTION

Abstract
This paper uses the Technical Efficiency/Agency Efficiency model to analyze why the telegraph
affected some industries differently than others in 19th century America. Before the introduction
of the telegraph, the US markets were inefficient and had poor information flow which made
integration rare. The telegraph was a revolutionary invention that reduced information costs and
expanded economies of scale. With the introduction of the telegraph some industries became
more competitive and others became more consolidated. The model presented shows that
whether an industry became more consolidated or more competitive depended on the level of
asset-specificity in the market. As examples, this paper uses the model to explain why wheat
became more competitive while meatpacking became more consolidated. The general framework
presented can be applied to the majority of the industries in the time period.

The Silent Revolution: Analyzing the Impact of the Telegraph on US Market Structure
The transportation revolution has long been cited as the principal cause of economic
growth in mid 19th century America, and while significant, it often overshadows another major
innovation. The invention of the telegraph transformed the very fabric of the US economy and
made coordination and communication possible at a higher level than ever before. This “silent
revolution” impacted almost every industry in the US economy. It expanded markets and sparked
waves of industry consolidation. The paradoxical nature of the telegraph may be one of the
reasons it is often skimmed over in studies of economic history. In some industries, it spurred an
increase in competition, in others it led to mass consolidation. The Technical Efficiency/Agency
Efficiency model provides a simple framework to analyze the impact of the telegraph on the
market structure of industries in the 19th century US economy.
This paper will first analyze the condition of US markets before the telegraph and give a
brief narrative of its invention. Next, the paper will explore the telegraph’s paradoxical impacts
under the lens of the Technical Efficiency/Agency Efficiency model. Finally, the paper will
show how this model can be applied to various industries to explain why they responded
differently to the introduction of the telegraph.
Market Structures Before the Telegraph
To fully appreciate the impact of the telegraph, it is important to understand the state of
the economy before its introduction. In general, it was characterized by small family firms
operating in regional markets. Farmers sold most of their produce to local merchants and
shopkeepers. The story of an Iowa merchant demonstrates the inefficiencies of this economy.
John Burrows was a merchant who bought and sold potatoes. Based on the news that prices in
New Orleans were a high $2/bushel, John travelled there to sell his 2,500 bushels. Along the

way, he was offered $0.50/bushel but turned it down in hopes of higher prices. Unfortunately,
John found upon arriving in New Orleans that the market had been saturated by other merchants.
John eventually sold the potatoes in exchange for coffee to a Bermuda ship captain for only
$0.08/bushel (Cronon, 1991). This story demonstrates the problem of poor communications
technology in the pre-telegraph economy. It was not irregular for merchants to travel long
distances based on uncertain prices.
Although in 1840 the economy remained primarily agricultural, with over 63% of the
labour force on farms, change was occurring rapidly. The proportion of the labour force in
manufacturing, though still at the low end of 9%, had tripled since 1810 (Boff, 1980). Urban
growth occurred in the same time frame, with an increased clustering into city sub-districts.
Although pre-industrial, the economy was ready for a change. As Boff (1980) states,
“The logic of business expansion was prodding firms to reach out for larger markets… [but this]
behaviour was constrained by the costs of establishing wider ranges of commercial contact” (p.
460). Despite the demand, the infrastructure in place was insufficient. In-land transportation was
slow and costly, done primarily on dirt roads. Communication relied on horse and stagecoaches.
This meant it took almost as long to send a message as it did to ship goods. The economy was
ready for the communication revolution.
The Invention of the Telegraph
While the transportation revolution of the mid 19th century has been widely documented,
the parallel communication revolution has received less notice. The invention of the railroad has
overshadowed the telegraph despite the fact that the benefits of one were only realized because
of the other. Although the railroad made it possible to ship goods quickly across the United

States, the levels of coordination needed for production on a nationwide scale would not have
been possible without the telegraph (Boff, 1980).
Chadler (2002) presents a compelling timeline of the rapid movements in the telegraph
industry. In 1844, the communication revolution started with Congress granting Samuel Morse
$30,000 to build an experimental telegraph line from Washington to Baltimore. This initiative
was a success, and the government passed the responsibility of further development onto the Post
Office in 1845. Due to financing issues in the next years, the projects were turned over to private
developers. This shift helped to expand the industry, and by 1852 23,000 miles had been laid.
Although the industry had low barriers to entry (due to minimal capital outlays), other factors led
to a consolidation. The firms quickly found there were significant returns to coordination, and
worked out cooperative arrangements to send messages across each other’s lines. This greatly
expanded their reach. In August 1857, the six leading telegraph companies signed a treaty that
divided the nation into six regions, but even this division posed problems and the industry soon
consolidated into three companies. Finally, in 1866, the three merged into the Western Union,
making it the first multi-union modern business enterprise in the US.
The example of the telegraph industry demonstrates a shift to monopolization that is
counter-intuitive for those well-versed in basic economic theory. The industry had low barriers to
entry and a business climate characterized by the free flow of information. Despite this, the
industry moved from a competitive market to a monopoly. Similar behaviour was mirrored by
many other industries. Now that the history has been presented, this paper will introduce some
relevant economic principles that can be used to explain why this occurred.

Economic Principles of Market Structures and Integration
To fully understand the impact of the telegraph on US industries, the reader must have a
basic knowledge of the factors that lead to industry consolidation. For the non-technical reader,
this presentation will be relatively general, with little reliance on mathematical formulas and
equations.
Yates (1986) applied market structure principles in her analysis of the telegraph. She
explained how industries with high asset specificity and complex product descriptions are more
likely to become integrated. Yates also discussed the trade-offs between the organizational forms
of the efficient market and integrated firms, citing high production costs and vulnerability costs
as characteristics of firms, and high coordination costs as characteristics of the market. This
analysis can be simplified using the Technical Efficiency/Agency Efficiency Trade-off model
described by Besanko, Dranove, Shanley, & Schaefer (2016).
The Technical Efficiency/Agency Efficiency model describes the trade-offs of
integration. Technical efficiency is a firm’s ability to minimize production costs. Agency
efficiency is a firm’s ability to minimize coordination and transaction costs. In general, markets
have higher technical efficiency and integrated firms have higher agency efficiency. To
determine whether firms will integrate, one must examine this trade-off. As Yates (1986)
described, the result of the trade-off ultimately depends on asset specificity.
Figure 1 collects this information into three curves. ΔT represents the minimum cost of
production by integrated firms minus the minimum cost of production in the market. ΔA
represents the minimum transaction costs for integrated firms minus the minimum transaction
costs in the market. ΔC is the sum of ΔT and ΔA and represents the cost difference between
integrated firms and the efficient market. When ΔC is positive the costs of integrated firms are

higher than the costs of the market and the market will prevail. When ΔC is negative, the costs of
integration are less than the costs of the market and integration will occur. ΔT and ΔA both fall
as asset specificity rises, increasing the appeal of integration. This model shows that whether an
industry will be characterized by integrated firms or a competitive market depends on asset
specificity.
The Impacts of the Telegraph
The telegraph enabled near instantaneous communication unlike anything seen before.
This technological breakthrough made both markets and integrated firms more efficient. Favoring
markets, the telegraph brought dramatic reductions in intermarket price differentials, information
costs, and transaction costs (Yates, 1986). This ushered in an era of near-perfect information.
Although this reduction in coordination costs also benefited integrated firms, it had a
proportionally greater effect on communication-intensive markets. Favouring integrated firms, the

telegraph helped to expand market areas, creating economies of scale that allowed firms to
drastically decrease production costs.
Since these two effects are opposing, it is initially unclear how the telegraph would affect
the market structure of an industry. We can use the Technical Efficiency/Agency Efficiency
model to identify which change is more significant. Since the telegraph changed communication
and production costs, the ΔT and ΔA curves will both shift. To examine the final impact, one
could look at an industry’s Technical and Agency Efficiency before and after the telegraph. A
simplified interpretation of these changes is that the post-telegraph era was the first-time firms
could seriously consider integration. The ability of an integrated firm to coordinate its operations
before the telegraph was near impossible, resulting in a ΔC so large it would almost never fall
below zero. This interpretation falls in line with Boff’s (1980) claim that “it makes little sense to
state that the telegraph ‘improved’ communication: one may as well contend that electricity
moves faster than railroads and horses” (p. 461). Under this simplification, we can make the
judgement that the more asset specific the industry, the more likely consolidation would occur. A
further study could calculate actual changes in the Technical and Agency Efficiency to determine
the extent of integration, but this would require significant data on the costs in each industry. In
this paper, we will adhere to the simplified analysis and show how it can be applied to two key
industries.
Industries that Remained Competitive: Wheat
By applying the presented model, the astute reader will recognize that the wheat industry,
with low asset specificity, had more to gain from the market-positive effects of the telegraph.
This means the telegraph would increase competitiveness in this industry. In the Technical
Efficiency/Agency Efficiency model, the wheat industry would be at a point to the left of k**

where the costs of integrated firms are higher than the cost of the market. Whereas in the
example presented by John Burrows there was considerable uncertainty around prices, the
telegraph gave traders throughout the country knowledge of the prevailing market prices. A
uniform grading system made it possible for buyers to distinguish quality (Yates, 1986).
Although local events used to be the primary influencers of prices, national and international
shocks became the driving factors. If local shocks forced up prices in one region, merchants
would go elsewhere. This would effectively decrease the demand and bring the regional price
back in-line with the market. The result was a nearly perfectly competitive market, with many
buyers and sellers and little differentiation between the goods.
Industries that Consolidated: Meat Packing
The meatpacking industry is an excellent example of how the telegraph impacted
industries with higher asset specificity. Although meat became considerably undifferentiated
with the introduction of a standardized grading system, its perishability made it time specific. If
the movement of a meat shipment was interrupted it could spoil. In our model, this is
characterized by a low ΔA curve, as the market was a very inefficient means to coordinate
complex movements. Yates (1986) stated that “[t]he telegraph ultimately played a significant
role in coordinating the integrated meat packing companies and, we can assume, in coordinating
any time specific product” (p. 160). The industry ultimately consolidated into a few major
players such as Swift and Armour. In the Technical Efficiency/Agency Efficiency model, this
industry would be at a point to the right of k** where the costs of integrated firms are lower than
the cost of the market. Given that Swift and Armour spent over $200,000 on telegraphic
communication a year, the importance of the telegraph for this industry was undeniable
(Chandler, 2002).

This application of the Technical Efficiency/Agency Efficiency model for the wheat and
meatpacking industries can be repeated to understand the impact of the telegraph on the many
industries of the 19th century US economy. This model helps simplify the seemingly paradoxical
effects of the telegraph.
Conclusion
The telegraph was one of the most influential innovations of its time. It rapidly changed
the majority of the industries in the US economy with the introduction of near instantaneous
communication. While expanding markets and reducing communication barriers, it’s effect on
US market structure ultimately depends on the industry in question. The Technical
Efficiency/Agency Efficiency Model can be applied to help understand its seemingly paradoxical
impacts. For future research, there is a need for a data-driven analysis of the telegraphs impact on
GDP, economic growth, and market structure using metrics like the Herfindahl’s index to
quantify the analysis in this paper. It is time that the silent communication revolution gets the
attention it deserves, and that the confusion surrounding the telegraph’s impact on market
structure is dispelled with simple economic analysis.
