Financial liberalization,financial sector development and growth: Evidence from Malaysia

The objective of this paper is to examine whether financial development leads to economic growth or vice versa in the small open economy of Malaysia. Using time series data from 1960 to 2001, we conduct cointegration and causality tests to assess the finance-growth link by taking the real interest rate and financial repression into account. The empirical evidence suggests that financial liberalization, through removing the repressionist policies, has a favorable effect in stimulating financial sector development. Financial depth and economic development are positively related; but contrary to the conventional findings, our results support Robinson's view that output growth leads to higher financial depth in the long-run.     

A general equilibrium analysis of software development: Implications of copyright protection and contract enforcement

We develop a general equilibrium model to study the implications of a legal environment on the organization of software production. We show that contract enforcement determines the organizational mode (i.e., in-house versus outsourcing) of customized software development while copyright protection affects both packaged software as well as customized software development. We obtain some testable results: when copyright protection is weak, only customized software will be developed; when copyright protection is strong, both customized software and packaged software will be developed; environment changes in one software market affect the equilibrium in the other software market.     

Transparency on the consumer side and tacit collusion

This paper investigates the effects on tacit collusion of increased market transparency on the consumer side of a market in a differentiated Hotelling duopoly. Increasing market transparency increases the benefits to a firm from undercutting the collusive price. It also decreases the punishment profit. The net effect is that collusion becomes harder to sustain. In the limiting homogeneous market, the effect vanishes. Here market transparency does not affect the possibilities for tacit collusion.     

Mergers, brand competition, and the price of a pint

Mergers in the UK brewing industry have reduced the number of national brewers from six to four. The number of brands, in contrast, has remained relatively constant. We analyze the effects of mergers on brand competition and pricing. Brand-level demand equations are estimated from a panel of draft beers. To model brand-substitution possibilities, we estimate the matrix of cross-price elasticities semiparametrically. Our structural model is used to assess the strength of brand competition along various dimensions and to evaluate the mergers. In particular, we compute equilibria of pricing games with different numbers of players.     

On Stackelberg games in a homogeneous product market

In a homogeneous product duopoly with concave demand and strictly convex costs we bring together all the standard results of quantity Stackelberg games, provide some new results with price Stackelberg games and compare the equilibrium configuration of the quantity games with the price games. In the price Stackelberg game we show there is a unique SPNE where the leader chooses a lower price than the follower, but both get equal payoffs. We prove that generally quantity Stackelberg games are less competitive than price Stackelberg games. However, we also demonstrate the possibility of a reversal of this result.     

Modelling cost complementarities in terms of joint production

Cost complementarities arise from synergies in the production of heterogeneous goods. It is shown that synergies can be accounted for in terms of shared public inputs (roughly) if and only if synergies decrease as the scope of production increases. This case of “substitutive” synergies is argued to be typical. The key technical tool is a novel interpretation of conjugate Moebius inversion in terms of higher-order differences.     

Corporate Restructuring in Japan Part I: Can M‐Form Organization Manage Diverse Businesses?

The purpose of this paper is to examine the recent organizational restructuring in Japan in the framework of organizational economics, assuming that the product/market portfolio of the firm is fixed. How does a firm set about organizing its internal divisions? I first summarize some stylized facts on corporate diversification strategy and multi‐divisional (M‐form) organization in large Japanese firms from different perspectives. I then analyse the problem of choosing an organizational form. In particular, I argue that, precisely because of its related diversification, the multi‐business Japanese firm adopting the M‐form finds it difficult to differentiate its diverse businesses internally.     

In-house competition, organizational slack, and the business cycle

Multiplant firms pit their facilities against each other for production assignments. The present paper studies the consequences of this practice in a model where production is limited by capacity constraints and asymmetric information allows facilities to accumulate slack. It shows the amount of slack per unit of output to be pro-cyclical. Indeed, as capacity constraints become more acute in economic booms, the power of in-house competition for quota assignments is reduced and slack per unit of output increases, while the opposite is true in downturns. Moreover, in downturns firms may use higher cost facilities even when lower cost plants are not running at capacity since this boosts X-efficiency in low-cost plants.     

Consumer inertia, firm growth and industry dynamics

We develop a model of firm size, based on the hypothesis that consumers are “locked in,” because of search costs, with firms they have patronized in the past. As a consequence, older firms have a larger clientele and are able to extract higher profits. The equilibrium of this model yields: (i) A downward sloping density of firm sizes. (ii) Older firms are less likely to exit than younger firms. (iii) Larger firms spend more on R&D.     

Gender differences in self‐employment

This paper examines the factors that influence transitions into self‐employment, paying particular attention to gender differences. We find that: (i) men are more responsive to the wage differential between wage/salaried employment and self‐employment; (ii) liquidity constraints are more important for men; and (iii) the link between father's self‐employment status and the probability of self‐employment is stronger for men. Taken together, these results suggest that, for women, self‐employment is a closer substitute for part‐time work and labour‐market inactivity than it is for men. We attribute such differences to the different labour market opportunities and occupational strategies of women.
