Does Idiosyncratic Risk matter in the Vietnamese
Stock Market?
The paper examines the behaviour of idiosyncratic volatility in the Vietnamese stock market from 2007-2012. Using daily and monthly data, we find that idiosyncratic volatility cannot predict one-month ahead stock returns in the stock market. Also, there is a positive trend in the average value-weighted idiosyncratic volatility, while the market volatility exhibits negative trend, implying […]

Public Policy and Industrial Transformation
in the Process of Development
This paper studies the role of public policy in promoting industrial transformation from an imitationbased, low-skill economy to an innovation-based, high-skill economy, where technological progress now occurs through the domestic invention of ideas. Industrial transformation is measured by changes in an index of industrial structure, defined as the ratio of the variety of imitation- to […]

The paper examines a motive for R&D cooperation with a rival by considering the behavior of a quality follower in a model of vertically differentiated products. We show that, in some settings, a quality follower has an incentive to contribute money...
Research and Development Cooperation Between Rivals: A Novel Motive
beyond New Knowledge
The paper examines a motive for R&D cooperation with a rival by considering the behavior of a quality follower in a model of vertically differentiated products. We show that, in some settings, a quality follower has an incentive to contribute money to R&D activity of a quality leader with the sole purpose of making the […]

In this paper, we construct a simple model to show why similar countries can trade with each other for the same good when product quality can be selected by firms. Specifically, we devise a model that shows when trade expands a market, firms will build...
Why Do Similar Countries Trade with Each Other for the Same Good?
In this paper, we construct a simple model to show why similar countries can trade with each other for the same good when product quality can be selected by firms. Specifically, we devise a model that shows when trade expands a market, firms will build higher quality into their goods that benefits the whole region. […]

Integrating managerial preferences into the assessment by the fuzzy AHP/DEA approach:
A case application in the assessment of university performance
In recent years, with the expansion of existing institutions as well as the establishment of new ones, higher education institutions have suffered the problem of declining available resources. Each university must assess the performance of its critical business units to measure effectiveness and efficiency. The purpose of this paper is to assess university performance. In […]

Intertemporal equilibrium with financial asset and
physical capital
We build an innite-horizon dynamic deterministic general equilibrium model with imperfect market (borrowing constraint) in which heterogenous agents invest in capital or nancial asset, work and consume, a representative rm maximizes prot. Firstly, the existence of intertemporal equilibrium is proved even if aggregate capital is not uniformly bounded. Secondly, we dene and study nancial bubble […]
