We study optimal investment with multiple assets in the presence of small proportional transaction costs. Rather than computing an asymptotically optimal no-trade region, we optimize over suitable trading frequencies. We derive explicit formulas for these and the associated welfare losses due to...

This paper uses a model with transaction costs and imperfect competition in the land market to analyze the efficiency and welfare effects of land reforms. We show that removing only one imperfection may have very different efficiency and welfare effects than would otherwise result from reforms...

The present study examines factor content of the CEE transition country agricultural trade. We examine the relative country abundance for labour, capital and land, and test the Heckscher-Ohlin-Vanek (HOV) hypothesis. Our empirical findings suggest that the factor content of agricultural exports...

In this paper we study factor content of the CEE agricultural trade. In order to account for differences in technology and factor prices in CEE, the theoretical framework of the present study builds on the previous work of Helpman (1984) and Staiger (1986) who consider a trade equilibrium in...

We consider a market consisting of one safe and one risky asset, which offer constant investment opportunities. Taking into account both proportional transaction costs and linear price impact, we derive optimal rebalancing policies for representative investors with constant relative risk...

For portfolio choice problems with proportional transaction costs, we discuss whether or not there exists a shadow price, i.e., a least favorable frictionless market extension leading to the same optimal strategy and utility. By means of an explicit counter-example, we show that shadow prices...
