Transaktionskomplexität

Transaktionskosten, or transaction costs, are the costs incurred in making an economic exchange other than the price of the good or service itself. These costs include searching for information, evaluating alternatives, negotiating and drafting contracts, and monitoring and enforcing agreed terms. They can be divided into ex-ante costs (information gathering, assessment, contract design) and ex-post costs (monitoring compliance, resolving disputes, adapting to changes).

The concept is central to transaction cost economics, associated with Ronald Coase and later Oliver Williamson. Coase argued that the choice between using markets or internal organizational structures depends on the relative size of transaction costs; when these costs are high, organizing production within a firm may be more efficient than relying on the market. Williamson extended the framework by identifying governance structures and factors such as asset specificity, uncertainty, and transaction frequency as determinants of the appropriate form of governance and the level of contract detail.

Applications of transaction cost analysis span many areas, including contract design, outsourcing decisions, supply chain management, and the development of institutions and platforms intended to reduce costs of exchange. Examples include standardized contracts, reputational mechanisms, formal and informal enforcement regimes, and online marketplaces that lower search and information costs. The concept also informs law and economics, political economy, and organizational theory by explaining why economic activity is organized through markets, hierarchies, or hybrids.

Critiques note challenges in measuring transaction costs, their context dependence, and the way technology and regulation continually reshape costs. Nevertheless, transaction costs remain a foundational tool for understanding how governance structures emerge and adapt to varying cost environments.
