Prebisch–Singer Hypothesis
Definition of the prebisch–singer hypothesis.
The Prebisch–Singer hypothesis is a theory in economics that suggests that the terms of trade between primary products and manufactured goods tend to deteriorate over time. This theory, posited by Raúl Prebisch and Hans Singer in the late 1940s and early 1950s, respectively, argues that countries that export commodities (a term closely associated with primary products) will become relatively poorer in comparison to those that export manufactured goods. The hypothesis is based on the observation that the income elasticity of demand for primary products is lower than that for manufactured goods. Thus, in a growing global economy, the prices for primary products will increase at a slower rate than those for manufactured goods, leading to a decline in the terms of trade for countries specializing in the export of commodities.
Consider two countries: Country A specializes in the production and export of copper, a primary commodity, while Country B specializes in the production and export of electronic gadgets, a manufactured product. As the global economy expands, the demand for electronic gadgets (with high-income elasticity) grows faster than the demand for copper (with lower income elasticity). Over time, the price of electronic gadgets increases more rapidly than the price of copper. Consequently, for Country A to purchase the same amount of electronic gadgets from Country B, it needs to export more copper than before. This illustrates the deteriorating terms of trade for Country A, as represented by the Prebisch–Singer hypothesis.
Why the Prebisch–Singer Hypothesis Matters
The Prebisch–Singer hypothesis has significant implications for trade policies and economic development strategies, especially for countries heavily reliant on the export of primary products. It supports the argument for these countries to diversify their economies and to develop their manufacturing sectors. The hypothesis also underpins the rationale for economic policies aimed at protecting infant industries and reducing dependency on commodity exports. It highlights the vulnerability of commodity-exporting countries to volatile global market conditions and the potential benefits of economic diversification and value addition.
Frequently Asked Questions (FAQ)
What are the main criticisms of the prebisch–singer hypothesis.
The Prebisch–Singer hypothesis has faced criticism on several fronts. Critics argue that it oversimplifies the dynamics of international trade by not accounting for factors such as technological progress and productivity gains in the primary sector, which can influence the terms of trade. Others suggest that the hypothesis underestimates the capacity of commodity-exporting countries to diversify their economies and to upgrade their production processes. Additionally, some economists have highlighted empirical evidence showing periods during which the terms of trade for primary products improved, contrary to what the hypothesis predicts.
How have some countries responded to the challenges highlighted by the Prebisch–Singer hypothesis?
Some countries have taken proactive steps to mitigate the challenges highlighted by the Prebisch–Singer hypothesis through policies aimed at economic diversification and industrialization. This includes investing in education and technology to improve productivity and competitiveness, implementing policies to support the growth of the manufacturing sector, and pursuing value-added processing of primary products. Countries have also engaged in regional trade agreements to enhance market access for their manufactured goods and reduce dependence on commodity exports.
How does the Prebisch–Singer hypothesis relate to the concept of sustainable development?
The Prebisch–Singer hypothesis is relevant to discussions of sustainable development, particularly in how it underscores the need for economic diversification and resilience in the face of global market volatility. By highlighting the risks associated with over-reliance on primary commodity exports, the hypothesis indirectly points to the importance of pursuing economic development strategies that are environmentally sustainable, economically viable, and socially inclusive. This includes promoting industries that not only generate economic growth but also contribute to environmental conservation and social well-being.
In conclusion, the Prebisch–Singer hypothesis has played a pivotal role in shaping economic thinking and policy-making related to international trade and development. Despite criticisms and challenges to its empirical validity, the core message of promoting economic diversification and reducing dependency on volatile commodity markets remains highly relevant, especially for developing countries seeking to achieve sustainable and inclusive economic growth.

In economics, the Prebisch–Singer hypothesis (also called the Prebisch–Singer thesis) argues that the price of primary commodities declines relative to the price of manufactured goods over the long term, which causes the terms of trade of primary-product-based economies to deteriorate.
The Prebisch-Singer hypothesis is an economic theory that suggests that the prices of primary goods (such as raw materials and agricultural products) tend to decline relative to the prices of manufactured goods over time.
