The tea leaf market in Country Zoperates under conditions that closely resemble perfect competition. The industry consists of thousands of small tea growers located across various regions, each producing tea leaves using similar cultivation methods and technology. No single producer is large enough to influence market prices, and tea leaves supplied by different growers are largely homogeneous in quality before processing. Market prices are publicly available through auction centers and online platforms, ensuring that both buyers and sellers have perfect information. In recent years, favorable climatic conditions and government support in the form of subsidized fertilizers led to a significant increase in tea production. As output expanded rapidly, the market experienced excess supply, resulting in a fall in tea leaf prices. Since growers are price takers, they were compelled to sell their produce at prevailing market prices, even when prices declined close to their average total cost (ATC). In the short run, many growers continued production despite earning losses because market prices still covered their average variable cost (AVC). Shutting down production would have led to even higher losses, as fixed costs such as land rent and equipment maintenance continued regardless of output. However, prolonged low prices placed financial pressure on high-cost growers who relied on outdated farming practices and inefficient input use. Over time, these high-cost producers gradually exited the market, either by shifting to alternative crops or leaving agriculture altogether. The exit of such growers reduced total market supply, which gradually pushed prices upward. Efficient producers with lower cost structures remained in the market and benefited from improved market conditions. In the long run, the tea leaf market reached an equilibrium where market price equaled the minimum average total cost, and all remaining growers earned only normal profit. Free entry and exit ensured efficient allocation of resources, prevented long-term economic losses or profits, and stabilized the market.

Why do tea growers continue production in the short run even when market price is lower than average total cost?

Critically assess whether government support measures can distort long-run equilibrium in a perfectly competitive market.
