In this paper, I focus on the extension of transaction costs to appropriative activity and coercive power in the property rights approach. It has been argued that including the costs of appropriation and violent enforcement in transaction costs is based on the assumption that Coaseian bargaining...

In this paper we deal with a utility maximization problem at finite horizon on a continuous-time market with conical (and time varying) constraints (particularly suited to model a currency market with proportional transaction costs). In particular, we extend the results in Campi and Owen (2011)...

We study the Leland model for hedging portfolios in the presence of a constant proportional transaction costs coefficient. The modified Leland's strategy recently defined by the second author, contrarily to the classical one, ensures the asymptotic replication of a large class of payoff. In this...

The enforcement of contracts is necessary for efficient exchange in economic activities. The predominance in agriculture of informal contracts leads in many countries to the implementation of specific legal rules for contract law. This article emphasises the complementarities between public and...

This paper considers whether it is differences in technical efficiency or differences in factor endowments that explain productivity differentials in Moldovan agriculture. We compute non-parametric measures of technical efficiency for a sample of Moldovan small-holders using the four-step Data...

New Institutional Economics, based on the Coasean comparative approach, offers a highly useful framework for research on environmental problems. We propose a tentative analytic framework for environmental problems and we try its heuristic power by first applying it to the Poitou-Charentes...
