This paper analyzes the portfolio decision of an investor facing the threat of illiquidity. In a continuous-time setting, the efficiency loss due to illiquidity is addressed and quantified. We show that the efficiency loss for a logarithmic investor with 30 years until the investment horizon is a significant 22.7% of current wealth if the illiquidity part of the model is calibrated to the Japan...

In this paper we compare the two standard forms of international investments in developing countries, debt and foreign direct investment, from a finance perspective. It is shown that the sovereign risks associated with debt finance are generally less severe than the ones which come with FDI. FDI is chosen only if the foreign investor is more efficient in running the project, if the project is r...

We study a discontinuous mispricing model of a risky asset under asymmetric information where jumps in the asset price and mispricing are modelled by Lévy processes. By contracting the filtration of the informed investor, we obtain optimal portfolios and maximum expected utilities for the informed and uninformed investors. We also discuss their asymptotic properties, which can be estimated usin...

Research has focussed on the impact that factors such as IT, marketplace process design and competition have on electronic marketplace performance. However, such research has neglected the impact of ownership upon the performance of an electronic marketplace. This paper explores the issue of ownership in electronic marketplaces and derives a broad, multi-faceted perspective of ownership, incorp...

We combine forward investment performance processes and ambiguity averse portfolio selection. We introduce the notion of robust forward criteria which addresses the issues of ambiguity in model specification as well as in preferences and investment horizon specification. It describes the evolution of dynamically–consistent ambiguity averse preferences. We first focus on establishing dual charac...

Using the Dow Jones Industrial Average Index record breaking days as a proxy for market wide attention, we show that as the aggregate stock market intensifies investor attention, stock market response to individual firms’ earnings announcements significantly increases. We hypothesize that there are many channels for the attention spill-over effect and document strong supportive evidence of one ...

Portfolio selection is a usual multiobjective problem. This paper will try to deal with the optimum portfolio for a private investor, taking into account three criteria: return, risk and liquidity. These objectives, in general, are not crisp from the point of view of the investor, so we will deal with them in fuzzy terms. The problem formulation is a goal programming (G.P.) one, where the goals...

We present a model in which wage-setting structures explain cross-country variation in corporate governance. The model predicts a nonmonotonic relationship between the level of centralization in wage-bargaining institutions and the levels of firm ownership concentration and investor protection legislation. Low and high degrees of centralization yield less concentrated ownership and more investo...
