According to Buchahan (1969), in the theory of choice, cost only exists before someone makes a choice. True False

False

According to Buchanan, uncertainty ensures that the evaluation of available alternatives by the chooser is the same as that of any external observer. True False

False

According to Hayek, the perfectly competitive model assumes away the essential characteristics of competition, which is inherently a static process. True False

False

Demesetz (1968) argues that the theory of natural monopoly provides a firm logic for why firms enjoying extreme economies of scale will charge monopoly prices. True False

False

In order to minimize their costs, producers will choose the bundle of inputs where (W/R) = (MPK/MPL). True False

False

Buchanan (1969) Cost and Choice

In "Cost and Choice," James Buchanan argues that the theory of economics should be focused on the study of decision-making processes rather than on the allocation of resources. He proposes that individuals have a subjective understanding of their preferences and make choices based on their subjective evaluation of the costs and benefits of each option. Buchanan emphasizes that costs are not just monetary expenses, but also include the opportunity costs of choosing one option over another. He also highlights the importance of understanding the institutional framework in which decision-making takes place, including the role of social norms, customs, and legal systems. Ultimately, Buchanan's analysis provides a framework for understanding how individuals make decisions and how institutions shape those decisions, which has significant implications for policy-making and economic theory.

Hayek (1996) The Meaning of Competition

In "The Meaning of Competition," Friedrich Hayek argues that competition is a process that enables individuals to discover and utilize dispersed knowledge in society, which is necessary for the efficient allocation of resources. He contends that competition is not just a rivalry among firms, but also a discovery process that enables individuals to learn from one another and adapt to changing circumstances. Hayek emphasizes that competition is not just limited to the market, but also exists in other spheres of life, such as science and politics. He also highlights the importance of institutions, such as property rights and the rule of law, in creating an environment that encourages competition and innovation. Ultimately, Hayek's analysis provides a framework for understanding the role of competition in economic and social life, and the importance of institutions in enabling individuals to engage in productive competition.

Coase (1937) - The Nature of the Firm

In "The Nature of the Firm," Ronald Coase argues that firms exist because it is more efficient to organize production under a single entity than through market transactions between individuals. He asserts that transaction costs, such as the costs of searching for suppliers and negotiating contracts, make the coordination of economic activity within a firm more efficient than through the price mechanism of the market. Coase also proposes that the size and boundaries of firms are determined by the costs of organizing production internally versus contracting out to external suppliers. Ultimately, his analysis provides a framework for understanding the role and structure of firms in the economy.

Demsetz (1968) Why regulate utilities?

In "Why Regulate Utilities?", Harold Demsetz challenges the conventional wisdom that government regulation is necessary to ensure that utility companies provide services at reasonable prices. He argues that the potential for competition among utilities and the ability of consumers to choose between different providers can serve as a check on the prices charged by utilities. Demsetz contends that government regulation often leads to inefficiencies, such as reduced incentives for innovation and a lack of responsiveness to changing consumer preferences. He proposes that instead of relying on regulation, policymakers should focus on creating an environment that encourages competition and enables consumers to make informed choices. Demsetz's analysis provides a framework for understanding the trade-offs between regulation and competition in the provision of utility services, and highlights the potential benefits of market-based solutions.

Costs in The Long Run vs. The Short Run

In long run cost, all the factors of production are variable, whereas, in the short run cost, at least one factor of production is fixed.

True

According to Coase (1937), firms will grow until the cost of organizing an additional transaction within the firm equals the cost of organizing that transaction in the market. True False

True
