**Unpacking Endogenous Timing in Mixed Duopoly: A Deep Dive into Price Competition**

The concept of endogenous timing in a mixed duopoly has been a topic of interest among economists, particularly in the context of price competition. A seminal study by J. C. Bárcena-Ruiz, published in the Journal of Economics in 2007, sheds light on this complex phenomenon. In this blog post, we’ll delve into the world of mixed duopolies, explore the idea of endogenous timing, and examine the implications of price competition.

**What is a Mixed Duopoly?**

A mixed duopoly is a market structure characterized by the presence of both private and public firms competing with each other. This type of market is common in industries such as healthcare, education, and utilities, where government agencies or state-owned enterprises coexist with private companies. The mixed duopoly setting presents a unique scenario, as the public firm’s objective may differ from that of its private counterpart. While private firms aim to maximize profits, public firms may prioritize social welfare or other non-profit goals.

**Endogenous Timing: A Key Concept**

Endogenous timing refers to the idea that firms choose when to make their decisions, rather than following a predetermined sequence. In other words, firms decide when to set their prices, taking into account the actions of their competitors. This concept is crucial in understanding price competition in mixed duopolies. By allowing firms to choose their decision-making timing, researchers can analyze how this flexibility affects market outcomes.

**Price Competition in Mixed Duopolies**

The study by Bárcena-Ruiz explores the impact of endogenous timing on price competition in a mixed duopoly. The author examines a model where a public firm and a private firm compete in prices, with the public firm aiming to maximize social welfare and the private firm seeking to maximize profits. The results show that, when firms choose their decision-making timing endogenously, the public firm’s price is more responsive to changes in market conditions than the private firm’s price. This finding has important implications for policymakers, as it suggests that public firms may play a crucial role in stabilizing prices and promoting market efficiency.

**Implications and Insights**

The study’s findings offer valuable insights into the workings of mixed duopolies and the role of endogenous timing in price competition. For instance, the results suggest that regulators should consider the timing of public firms’ decisions when designing policies aimed at promoting competition and social welfare. Additionally, the study highlights the importance of understanding the objectives and behavior of public firms in mixed duopolies, as these factors can significantly impact market outcomes.

**Conclusion**

The concept of endogenous timing in mixed duopolies offers a rich area of study, with significant implications for our understanding of price competition and market outcomes. The study by Bárcena-Ruiz provides a valuable contribution to this field, shedding light on the complex interactions between public and private firms in mixed duopolies. As researchers continue to explore this topic, we can expect to gain a deeper understanding of the mechanisms driving competition and social welfare in these markets.
