What Price Elasticity Of Supply (PES) Estimate Is Most Likely To Apply To The Supply Of Raw Coffee Beans? Why Is The Short-run Supply Of Fresh Flowers For Export From Kenya To The UK Less Price Elastic Than The Supply Of Green Beans?
When considering the price elasticity of supply (PES) for raw coffee beans, it's essential to understand the factors that influence a producer's ability to respond to price changes. Price elasticity of supply measures the responsiveness of the quantity supplied of a good or service to a change in its price. The supply of raw coffee beans is influenced by several factors, including the time it takes to grow coffee plants, the availability of land, and the costs associated with harvesting and processing. Given these considerations, let's analyze the provided options to determine which PES estimate is most likely to apply to the supply of raw coffee beans.
Understanding the Options
A) 0.1
A PES of 0.1 suggests that the supply is highly inelastic. This means that a 1% change in price would lead to only a 0.1% change in the quantity supplied. Such a low elasticity is typical for goods that are difficult to produce quickly or have significant constraints on resources.
B) 1
A PES of 1 indicates unitary elasticity. In this scenario, a 1% change in price results in a 1% change in the quantity supplied. This is a balanced response, suggesting that producers can adjust their output proportionally to price changes.
C) 1.1
A PES of 1.1 implies that the supply is relatively elastic. A 1% change in price would lead to a 1.1% change in the quantity supplied. This suggests that producers are quite responsive to price changes, and can increase their output significantly when prices rise.
D) 10
A PES of 10 represents a highly elastic supply. A 1% change in price would result in a 10% change in the quantity supplied. This extreme responsiveness is rare but can occur in industries with very flexible production capabilities and minimal constraints.
Factors Affecting PES of Raw Coffee Beans
Several factors influence the PES of raw coffee beans. Firstly, the time required to grow coffee plants is a crucial determinant. Coffee plants take several years to mature and produce beans, meaning that producers cannot quickly increase supply in response to a price hike. This biological constraint makes the short-term supply relatively inelastic. Secondly, the availability of land suitable for coffee cultivation is limited in many regions. Expansion of coffee farms may require significant investment and time, further restricting the immediate supply response. Thirdly, harvesting and processing coffee beans involve labor-intensive processes. The availability and cost of labor can impact how quickly producers can increase supply. Finally, storage capacity and the shelf life of coffee beans can also play a role. If beans can be stored for extended periods without significant loss of quality, producers may have more flexibility in their supply response.
Determining the Most Likely PES Estimate
Considering the factors above, the supply of raw coffee beans is likely to be inelastic, but not perfectly so. The long growth period and land constraints mean that producers cannot drastically increase supply in the short term. However, they are not entirely unresponsive to price changes. They might adjust harvesting efforts, utilize existing stock, or make marginal expansions in production. Therefore, a PES of 0.1 is likely too low, as it suggests an almost fixed supply. A PES of 10 is also improbable, as it indicates an extremely responsive supply, which is not realistic for coffee beans. A PES of 1.1 suggests a fairly elastic response, which might be more applicable in the long term but less so in the immediate short term. A PES of 1, indicating unitary elasticity, is a plausible scenario where producers adjust output proportionally to price changes, reflecting a moderate level of responsiveness.
Based on these factors, a PES of A) 0.1 is the most likely to apply to the supply of raw coffee beans in the short term. While producers can adjust their output to some extent, the inherent constraints in coffee production make the supply relatively inelastic. This means that changes in price will have a limited impact on the quantity of raw coffee beans supplied.
The second part of the question addresses why the short-run supply of fresh flowers for export from Kenya to the UK is less price elastic than the supply of green beans. This comparison highlights the differences in production and transportation factors that affect the price elasticity of supply for these two commodities.
Key Differences in Supply Chain
Perishability
Perishability is a critical factor. Fresh flowers are highly perishable, meaning they have a very short shelf life. This necessitates rapid harvesting, processing, and transportation to maintain their quality and market value. In contrast, green beans have a longer shelf life and can withstand more extended periods between harvesting and sale. This difference in perishability significantly impacts the supply response to price changes.
Transportation
Transportation requirements also play a crucial role. Fresh flowers require specialized handling and transportation to prevent damage and spoilage. They often need to be transported in refrigerated containers and by air freight to reach international markets like the UK quickly. This specialized transportation adds to the cost and complexity of the supply chain. Green beans, while also requiring careful handling, do not necessitate the same level of urgency and specialized transport, making their supply chain more flexible.
Production Cycle
The production cycle for flowers and green beans differs significantly. Flowers, particularly those grown in greenhouses, can have a relatively shorter production cycle compared to green beans. Some flower varieties can be harvested multiple times a year, allowing for quicker adjustments in supply. Green beans, on the other hand, may have a more extended growing season and fewer harvest cycles, limiting the immediate supply response.
Market Conditions
Market conditions and contracts can also influence the supply elasticity. Flower growers often operate under contracts with distributors and retailers, which may specify the quantity and timing of deliveries. These contractual obligations can limit the growers' ability to respond to sudden price changes in the spot market. Green bean suppliers may have more flexibility in their sales arrangements, allowing them to adjust their supply more readily.
Implications for Price Elasticity
Given these differences, the short-run supply of fresh flowers is less price elastic due to the constraints imposed by perishability and specialized transportation. The need for rapid delivery and specialized handling limits the ability of suppliers to increase supply quickly in response to higher prices. If prices rise, flower growers may be constrained by their harvesting capacity, transportation logistics, and contractual obligations. This inelasticity means that a significant price increase might only result in a small increase in the quantity of flowers supplied.
In contrast, the supply of green beans is more price elastic because of their longer shelf life and less stringent transportation requirements. Green bean suppliers have more time to harvest and transport their produce, allowing them to respond more effectively to price incentives. If prices rise, they can increase harvesting efforts, utilize existing stock, and arrange for additional shipments more easily than flower growers.
Conclusion
In summary, the short-run supply of fresh flowers for export from Kenya to the UK is less price elastic than the supply of green beans primarily due to the perishability of flowers and the specialized transportation they require. These factors limit the ability of flower suppliers to respond quickly to price changes, resulting in a less elastic supply curve compared to that of green beans.
In conclusion, determining the price elasticity of supply (PES) for agricultural products like raw coffee beans and fresh flowers requires a comprehensive understanding of various factors. For raw coffee beans, the long growth period, land constraints, and labor-intensive harvesting processes contribute to a relatively inelastic supply, making a PES of 0.1 a likely estimate. In contrast, the short-run supply of fresh flowers is less price elastic than that of green beans due to the perishability of flowers and the specialized transportation they require. These insights are crucial for policymakers, producers, and consumers in making informed decisions about supply, demand, and pricing in these agricultural markets.
