The usual belief is that the China's state enterprise reform with contract management responsibility system has led state-owned enterprises to maximize profit. Nonetheless the poor performance of state-owned enterprises after the reform relative to other forms of enterprises remains a puzzle. As...

Causal observation shows that many developing countries adopt certain strategic trade measures such as export subsidies and domestic currency devaluation to promote their exports. Are there any economic rationality behind these measures? The answer is yes. Using a general equilibrium model, we...

Both the theory and practice of using hedonic regressions to quality adjust inflation estimates are implicitly developed for monopolistic competitive markets. We demonstrate conditions required for consistent OLS estimation of hedonic regression for an oligopoly. To reflect firm heterogeneity,...

In early 1998, the new Chinese Premier Zhu Rongji proposed an ambitious new reform plan, which aims to solve the problems of state-owned enterprises (SOEs) within three years. Among these problems, overstaff in SOEs is a key and difficult issue attracting wide concern. This paper establishes a...

The static differentiated product demand model when applied to products with rapid product turnover and declining prices, yields implausible results. One response is to explicitly model the inter-temporal choices of consumers but computational demands require restrictive assumptions on consumer...

This paper considers the situation where some firms in an industry collude together as an RJV cartel to compete with other firms who individually engage in R&D. The analysis shows that this partial RJV cartelisation may increase market concentration. In comparison with pure R&D competition,...

Many companies supplying consumption goods and services provide their shareholders with price discounts when they consume them. Although this practice is not uncommon it has not been analysed to date. This paper presents a simple model describing shareholder discounts and consequent market...

This paper considers a three-stage game of a differentiated oligopoly: firms first make their entry decisions, then they choose production technologies and in the third stage of the game they decide product prices. The technology choice can be understood as selecting a technology from a pool of...

Built on the location model, this paper studies the rivalry of two firms in an industry through two-part tariffs. It is found that kinky profit functions are responsible for the coincidence of imperfectly competitive equilibrium and cartelization outcome. A duopoly likely results in higher entry...
