Trade and Personal Distribution of Wealth and Income: Beyond the Stolper–Samuelson Theorem

The effect of international trade on personal distribution of wealth and income is examined via the Stolper–Samuelson Theorem. It is shown that free trade between North and South increases (decreases) wealth and income inequality in the North (South). A concept of three classes – lower, middle and upper – is developed. It is shown that North–South free trade in goods leads to a middle class squeeze in the North and a middle class expansion in the South.     

Strategic Environmental Policy with Technology Licensing

The tendency for countries to cheat on international environmental agreements has been well-documented. One reason is that less developed countries suffer technological disadvantages. While a number of authors have shown that technological transfers can solve the stability problem, real-world giveaways rarely occur. The purpose of this study is to investigate the conditions under which private licensing of pollution abatement technology, linked to cooperation on environmental policy, represents a feasible alternative. We find that, while a Pareto-improving solution exists, the licensing equilibrium is tenuous. Ironically, the more technologically advanced pollution abatement becomes, the less incentive there is for the recipient to cooperate.     

Computing optimal rebalance frequency for log-optimal portfolios in linear time

The pure form of log-optimal investment strategies are often considered to be impractical due to the inherent need for continuous rebalancing. It is however possible to improve investor log utility by adopting a discrete-time periodic rebalancing strategy. Under the assumptions of geometric Brownian motion for assets and approximate log-normality for a sum of log-normal random variables, we find that the optimum rebalance frequency is a piecewise continuous function of investment horizon. One can construct this rebalance strategy function, called the optimal rebalance frequency function, up to a specified investment horizon given a limited trajectory of the expected log of portfolio growth when the initial portfolio is never rebalanced. We develop the analytical framework to compute the optimal rebalance strategy in linear time, a significant improvement from the previously proposed search-based quadratic time algorithm.     

The Asian economy: current state of play and future prospects

The global financial crisis, the so-called great world recession and recovery have had a serious impact on the Asian and global economies. Together, they managed to engender significant transformation in the contours of both the Asian and global economies. For instance, Asian economies presently depend less on markets in the advanced industrial economies and, due to their enlarging markets, can and did make a substantive contribution to the global recovery. They spearheaded the economic recovery from the global financial crisis. The post-crisis Asian economy is the third pole of the global economy. Significantly, the emerging market economies of Asia did not magnify the external shock this time and performed more like the advanced industrial economies. After a robust recovery in 2010, growth became somewhat subdued in 2011. Projections show that economic performance in the region in 2012 will not be very different from that in 2011 (see WB [World Bank] 2012).     

Computing optimal rebalance frequency for log-optimal portfolios

Log-optimal investment portfolio is deemed to be impractical and cost-prohibitive due to inherent need for continuous rebalancing and significant overhead of trading cost. We study the question of how often a log-optimal portfolio should be rebalanced for any given finite investment horizon. We develop an analytical framework to compute the expected log of portfolio growth when a given discrete-time periodic rebalance frequency is used. For a certain class of portfolio assets, we compute the optimal rebalance frequency. We show that it is possible to improve investor log utility using this quasi-passive or hybrid rebalancing strategy. Simulation studies show that an investor shall gain significantly by rebalancing periodically in discrete time, overcoming the limitations of continuous rebalancing.     

On measures of technical inefficiency and production uncertainty in stochastic frontier production model with correlated error components

Analysis of the behavior of technical inefficiency with respect to parameters and variables of a stochastic frontier model is a neglected area of research in frontier literature. An attempt in this direction, however, has recently been made. It has been shown that in a “standard” stochastic frontier model that both the firm level technical inefficiency and the production uncertainty are monotonically decreasing with observational error. In this paper we show, considering a stochastic frontier model whose error components are jointly distributed as truncated bivariate normal, that this property holds if and only if the distribution of observational error is negatively skewed. We also derive a necessary and sufficient condition under which both firm level technical inefficiency and production uncertainty are monotonically increasing with noise-inefficiency correlation. We next propose a new measure of the industry level production uncertainty and establish the necessary and sufficient condition for firm level technical inefficiency and production uncertainty to be monotonically increasing with industry level production uncertainty. We also study the limiting probabilistic behavior of these conditions under different parametric configuration of our model. Finally we carry out Monte Carlo simulations to study the sample behavior of the population monotonic property of the firm level technical inefficiency and production uncertainty in our model.

Tourism Competitiveness and the Role of Fractionalization

This study explores the impact of ethno‐linguistic fractionalization on tourism competitiveness. Using the 2009 Travel and Tourism Competitiveness Index, a comprehensive measure of tourism competitiveness developed by the World Economic Forum, this study provides evidence that while ethno‐linguistic fractionalization negatively impacts tourism competitiveness across nations, this effect is mitigated in wealthier countries. The results suggest that policy makers operating in less developed and more fractionalized countries should make a concerted effort to enhance economic development and strengthen the institutions, infrastructure, and overall business and economic environment needed to support and foster a successful tourism industry.

Direct Foreign Investment Versus Licensing

This paper examines the choice among alternative modes of direct foreign investment, namely, the wholly owned subsidiary (the S option) and joint venture (the J option), vis-à-vis licensing (the L option). The focus is on the role of moral hazard, difference in risk attitude and the prospect of the host country's policy toward the venture. An apparently surprising result is that riskiness of the project is a factor against the J option. Moreover, in the absence of policy intervention, L is dominated by either S or J, whereas if there is an anticipation of policy intervention (i.e., there is a policy moral hazard) L may emerge as the best option.
