This paper analyzes the trade-growth nexus by introducing two novel indicators that can capture demand and supply attributes of countries’ quality of specialization using a long-term, product-level, cross-country dataset. The Schumpeterian efficiency index tracks the technological dynamism of the export baskets as indicated by product-level patent intensities, while the Keynesian efficiency index gauges the demand attractiveness of the export baskets by estimating product-level demand elasticities and weighting them by diversification. The duration of growth episodes, defined as periods lasting longer than 8 years with average growth of 2% and even longer with exceptional growth episodes (|$’geq’,5’%$|), can be effectively explained by these two dimensions of specialization quality. Our findings, which hold up well to a wide range of controls, indicate that specialization in and of itself is bad for growth resilience, while nations with a diversified export structure that specializes in either demand-elastic or technologically dynamic productions are more likely to have longer growth episodes.
Since the beginning of political economy, at least since Serra (1613), who was perplexed by the relative wealth of Venice compared to Naples despite the latter’s lack of the majority of primary resources, the relationship between output composition and growth has been a major theme. Ferrier (1805) later considered the significance of manufacturing for the potential development of the European continent, particularly for France. List (1904), as reconstructed by Reinert (2007), continued to address and explain the process of catching up with this as a central theme.
The problem can be boiled down to three key interdependencies: (i) variations in products’ dynamic increasing returns, (ii) chances for learning and innovation, and (iii) demand elasticity to income. The technology gap/evolutionary theory of trade and growth (Dosi et al.) then rediscovers the theme. , 1990), which categorizes products and industries based on their Schumpeterian efficiency along the aforementioned dimensions (i e. learning potential) and Keynesian efficiency (i. e. demand potential). According to the structural-evolutionary theory of growth, making potato chips and making microchips do not have the same potential for growth (Dosi et al. , 2021). Such inter-product differences have more recently been observed and studied using artificial indicators that combine trade specialization and country performance (Hidalgo et al. , 2007; Tacchella et al. , 2013).
But it’s important to comprehend output composition in relation to ongoing structural change processes. In actuality, national patterns of export and production change over time. Indeed, structural changes are at the heart of contemporary economic growth in such a way that the two are closely related (Syrquin, 1988):
Even though these patterns of change in the composition of production and export along the path of development are far from constant, there do seem to be solid statistical regularities in the dynamics of broad aggregates like agriculture, industry, and services (Kuznets, 1971). However, the methods used by various nations to ascend the ladder and ultimately their degree of success vary (Chang, 2011). In fact, they risk remaining stuck in unfavorable development trajectories if they choose to specialize in undesirable products, such as those with productivity that is stagnant or declining or whose demand is extremely volatile, as in the case of natural resources. On the other hand, successful growth experiences are supported by structural change that favors more complex sectors with greater learning potential and facing international demand expansions (more in Dosi et al. , 1990; Dosi and Tranchero, 2021).
Growth prospects are influenced by both domestic and foreign trade, allowing countries to capitalize on global demand and potentially avoid consumption bottlenecks that are typical of the development process. Likewise, the first objective of this work is to determine the significance of “quality of specialization” on the growth process while accounting for various stages of development. In actuality, each nation’s growth rates are influenced by both more enduring structural forces of change and short-run fluctuations related to regional or global macroeconomic turbulence—e g. the creation of backward and forward intersectoral links (Hirschman, 1958), as well as the Schumpeterian “fits and starts” connected to instances of innovation and imitation
It has been noted in the empirical growth literature that stable trajectories are less frequent than is typically anticipated. Pritchett (2000), for instance, has demonstrated that growth experiences are typically not long-lasting, both over time and across countries. The complicated relationships between “cycle” and “trends” should not be discussed in this context. More modestly, we’ll look for any correlations between the output (product) composition of the different countries, as indicated by the export structure, and the cyclicality and persistence of their growth patterns, as well as the likelihood of exceptional growth spurts. These are the work’s second and third major tasks.
In more detail, we first create three indicators to describe countries’ productive composition and subsequent trade flows using long-term, cross-country, 4-digit level data on trade flows. The first indicator is a typical Balassa specialization index, which ignores any unique characteristics of each good. This index captures revealed comparative advantages, irrespective of their “quality. The second metric, known as Keynesian specialization efficiency, reflects demand patterns by balancing the diversification of export flows with the income elasticities of importing nations at the product level. The third, known as Schumpeterian specialization efficiency, combines trade and patent data and weights exports according to the intensity of their patents, viewed as a proxy for the opportunity for technological learning that they incorporate.
The relationship between the three indicators of export structure—also viewed as a proxy for a country’s structure of good production given the lack of direct data at the product level—and growth patterns is then examined. The latter are examined in terms of growth rates, growth volatility, and length of growth spells, i.e. e. persistent growth episodes lasting at least 8 years and exceeding a particular average growth threshold
According to our analysis, patterns of increasing sheer specialization have a negative relationship with the average growth rate, which increases its volatility and decreases the likelihood of sustained successful growth experiences. The opposite holds for diversification patterns into “virtuous”—i. e. having production and export efficiencies that are Keynesian and Schumpeterian, exhibiting higher growth rates, lower volatility, and longer growth spurts.
Specialization vs. Diversification
What is specialization?
A company focusing on a constrained range of production and providing goods and services for a predetermined range of uses is known as specialization. Businesses may choose to focus on a particular product or customer need, constantly enhancing those products to boost sales. By concentrating all of their resources and attention on a single market, independent businesspeople can also specialize in a single good or service. In an economic sense, specialization has lower risk than diversification, despite the fact that it can eliminate opportunities for market growth.
What is diversification?
To strengthen a business portfolio, diversification is a business strategy that focuses on introducing numerous products, services, locations, and clients. Any industry or business endeavor, including both individuals and entities, can benefit from diversification. Businesses can use diversification to slightly or significantly increase their stock at a higher risk. Individual businesspeople can engage in diversification by independently increasing their set of skills, resources, or services available to clients. All diversification involves some risk, but management can reduce it by carefully scheduling resources, production schedules, and marketing expectations in advance.
Diversification vs. specialization
Because specialization and diversification are very different business strategies, there are numerous differences between their aims, effects, and approaches to a market. Some differences between diversification and specialization include:
Goals
By accepting various profit opportunities, diversification in business aims to increase marketing opportunities. Businesses with greater product diversity, more effective production methods, and new service opportunities for their clientele all benefit from diversification. While diversification can reach a previously untapped market, at its lowest risk, it aims to expand the range of products based on goods that the company has already sold. For instance, while a skincare company can diversify its market by selling skincare books, a less risky diversification strategy might be to sell skincare products other than what they are currently able to produce.
To increase overall profit, effective diversification strategies launch new products that appeal to both existing and potential customers. Increasing a business’s value to a current client is another aim of diversification. For instance, a company might expand its offerings to include tutorials on skin care routines in addition to the sale of skin care products. Additional goals of diversification include the following:
The objective of specialization is to boost output in a particular good or service in order to better secure a business’s clientele. Businesses that specialize might enhance products that they already sell consistently to boost sales. Although specialization strategies may also involve developing new products, these items hardly ever give customers access to novel ideas or services. For instance, a company that specializes in technology might sell a new kind of mobile device rather than another computer, but they haven’t expanded their marketing options.
Instead of entering a new economic market, they increase their specialization profits by providing goods or services using the same marketing strategies. To boost sales of their current products, specialized markets might release improved versions of a product a second time or work with rivals in joint ventures. Additional goals of specialization include the following:
Risks
Diversification carries some economic risk by necessitating financial or time investments. Less profit than the company typically makes from more well-known products can result from expanding a business to produce materials or services that it did not previously offer. Business diversification can boost profits and increase recognition of the entire company brand if it is properly promoted. Instead of launching a brand-new product line all at once, allowing for gradual diversification through product availability margins may help reduce costs over time.
Additionally, promoting fresh goods alongside well-received goods may increase the likelihood of higher profits. Businesses can diversify their product lines while also managing risk effectively if management does market research before investing. Marketing goods in related marketing niches, such as piano books and piano lessons, is another way a company can reduce risk during diversification. Other risks involved with diversification include:
While specialization carries less risk than diversification, it can still pose an economic risk to a business. Over-specialization or a lack of diversification in a company’s target market could result in declining profits because of a dearth of clients. It may not be profitable for a company to forgo diversification if it sells a product without making any industry expansions. For instance, if a business only sells pen caps and not pens, paper, or other office supplies, it might not make as much money from pen cap sales alone. Other risks from specialization include:
Requirements
To offset increased production, a business may diversify within itself by buying supplies, investing in personnel, or constructing new facilities. The company might require more staff in order to produce a good or provide customers with services. Each quarter, hiring outside companies may be necessary to provide services like an online help desk, tutorials, or product reviews. In order to diversify new products, production facilities may need to be expanded or brand-new product lines may need to be launched. Because diversification may involve producing for markets that the company currently has little access to, the company might also need to invest in employee training.
Although it doesn’t require switching to a different industry, specialization may require hiring personnel, constructing additional production facilities, or making material purchases. While specialization can reduce risks and expenses for a business’ cash flow, it still necessitates different products or increased production of the same product. Regardless of their target markets, diversification and specialization both result in higher production costs.
Actions
With the help of marketing, production, and timely releases, diversification provides existing customers with new goods and services from various industries. A business may profit from providing a delivery date that customers can look forward to when releasing a new product to its customer base to increase initial product sales. Companies can launch extensive marketing campaigns to advertise to new customers as well as remind their current customers about the new product in order to diversify as much as possible to their existing customer base. Other actions a company may take when diversifying products include:
Because customers are familiar with the company’s industry through specialization, the business may not need to develop marketing campaigns aimed at attracting new clients. Instead, it might be beneficial for a business to market its products by launching them alongside ones that were successful with its existing customer base. Otherwise, specialization might entail enhancing the effectiveness of processes, staff, and profits. Other actions a company may take when undergoing specialization include:
Importance
Both specialization and diversification are crucial for a company’s financial health. With specialization, a business can dominate a market and boost profits by winning over loyal customers. A business can continue to grow its market and increase its profits by diversifying. Utilizing both in balance rather than just one or the other can aid in the development of a company that develops and expands economically.
