We consider the optimal intertemporal consumption and investment policy of a constant absolute risk aversion (CARA) investor who faces fixed and proportional transaction costs when trading multiple risky assets. We show that when asset returns are uncorrelated, the optimal investment policy is to keep the dollar amount invested in each risky asset between two constant levels and upon reaching e...

The purpose of the paper is to discuss the effects of WTO accession on policy-making and institutional reforms in transition countries. This is done by looking at the experience of those transition countries which are already Members of the WTO. We start by examining the effect of accession on trade policy and distinguish between the effects of accession negotiations and those of autonomous pol...

We analyze the investment decision of a firm that has an option to complete an investment project either in one lump or in two smaller parts at distinct points in time. The firm faces a trade-off between the cost savings that arise when the project is completed at once and the additional flexibility that arises when the firm is able to respond to resolving uncertainty by choosing optimal timing...

This paper studies the reality and the potential for green industrial policy. We provide a summary of the green industrial policies, broadly understood, for five countries. We then consider the relation between green industrial policies and trade disputes, emphasizing the Brazil-US dispute involving ethanol and the broader US-China dispute. The theory of public policy provides many lessons for ...

We provide a model of rational bubbles in a DNK framework. Entrepreneurs are heterogeneous in investment efficiency and face credit constraints. They can trade bubble assets to raise their net worth. The bubble assets command a liquidity premium and can have a positive value. Monetary policy affects the conditions for the existence of a bubble, its steady-state size, and its dynamics including ...

In the standard real options approach to investment under uncertainty, agents formulate optimal policies under the assumptions of risk neutrality or perfect capital markets. However, in most situations, corporate executives face incomplete markets either because they receive compensation packages that restrict their portfolios or because cash flows from the firm’s investment opportunities are n...

At present, there is no consensus in the literature concerning the influence of different credit financing on investment efficiency of enterprises, especially the lack of empirical evidence in developing countries. In this paper, based on the World Bank enterprise survey data, using the Heckman sample selection model, we study the effects of bank credit and trade credit on investment efficiency...

 Libya experienced a substantial increase in oil revenue as a result of increased oil prices during the period of the late 1970s and early 1980s, and again after 2000. Recent increases in oil production and the price of oil, and their positive and negative macroeconomic impacts upon key macroeconomic variables, are of considerable contemporary importance to an oil dependent economy such as that...

Regionalism is an integral part of the broader economic policy reforms that have occurred in the Western Hemisphere over the last decade. This chapter examines the dynamic effects of regional integration arrangements in the Western Hemisphere on the U.S. economy, including U.S. agriculture and agricultural trade, by taking into account changes in saving-investment and capital accumulation.
