Endogenous Transaction Costs

The paper proposes an alternative general equilibrium formulation of financial asset economies with transactions costs. Transaction costs emerge endogenously at equilibrium and reflect agents decisions of intermediating financial activities at the expense of providing labor services. An equilibrium is shown to exist in the case of real asset structures.

Transaction Costs and Institutions

This paper proposes a simple framework for understanding endogenous transaction costs - their composition, size and implications. In a model of diversification against risk, we distinguish between investments in institutions that facilitate exchange and the costs of conducting exchange itself. Institutional quality and market size are determined by the decisions of risk averse agents and conditions are discussed under which the efficient allocation may be decentralized. We highlight a number of differences with models where transaction costs are exogenous, including the implications for taxation and measurement issues.Exchange costs, transaction costs, general equilibrium, institutions..

New evidence of the effect of transaction costs on residential mobility

Transaction costs have attracted considerable attention in the theoretical literature on residential mobility. In many European countries, these costs mainly consist of ad-valorem transaction costs. In the current paper, we demonstrate empirically for the Netherlands that the transaction costs have a strong negative effect on the owners' probability of moving. Under a range of different specifications, it appears that a one percent-point increase in the value of transaction costs - as a percentage of the value of the residence - decreases ownership to ownership residential mobility rates by eight percent. Our estimates are consistent with the observation that in the Netherlands ad-valorem transaction costs mainly consist of buyer transaction costs.

Market Equilibrium with Transaction Costs

Identical products being sold at different prices in different locations is a common phenomenon. Price differences might occur due to various reasons such as shipping costs, trade restrictions and price discrimination. To model such scenarios, we supplement the classical Fisher model of a market by introducing {\em transaction costs}. For every buyer $i$ and every good $j$, there is a transaction cost of \cij; if the price of good $j$ is $p_j$, then the cost to the buyer $i$ {\em per unit} of $j$ is p_j + \cij. This allows the same good to be sold at different (effective) prices to different buyers. We provide a combinatorial algorithm that computes $\epsilon$-approximate equilibrium prices and allocations in $O\left(\frac{1}{\epsilon}(n+\log{m})mn\log(B/\epsilon)\right)$ operations - where $m$ is the number goods, $n$ is the number of buyers and $B$ is the sum of the budgets of all the buyers
