THE SQUARED ORNSTEIN-UHLENBECK MARKET

We study a complete market containing J assets, each asset contributing to the production of a single commodity at a rate that is a solution to the squared Ornstein-Uhlenbeck (Cox-Ingersoll-Ross) SDE. The assets are owned by K agents with CRRA utility functions, who follow feasible consumption/investment regimes so as to maximize their expected time-additive utility from consumption. We compute the equilibrium for this economy and determine the state-price density process from market clearing. Reducing to a single (representative) agent, and exploiting the relation between the squared-OU and squared-Bessel SDEs, we obtain closed-form expressions for the values of bonds, assets, and options on the total asset value. Typical model parameters are estimated by fitting bond price data, and we use these parameters to price the assets and options numerically. Implications for the total asset price itself as a diffusion are discussed. We also estimate implied volatility surfaces for options and bond yields.     

Tinbergen in De Economist

Jan Tinbergen's scientific writings cover six main areas of research. His articles in De Economist represent these areas; in some cases the contributions to De Economist were of a pioneering nature (business cycles, economic models, economic integration); in others De Economist was the first or even single outlet for Tinbergen's work. This article provides an overview of these contributions. The wide scope of Tinbergen's areas of research goes together with a unity in approach, the characteristics of which are: policy relevance, quantification and measurement, balance in analysis and presentation, and learning from experience. Tinbergen's articles in De Economist bear witness to this approach which at the time also met with scepticism and resistance as this overview shows. According to Houthakker, Tinbergen's main contribution may be that, amidst the pleas of interest groups and the slogans of the laity, an attempt is made that the voice of the professional economic researcher be heard. Tinbergen's work still sets an agenda for both economic research and policy making.     

A variety-increasing view of the development of the semiconductor industry in Taiwan

The development of the semiconductor industry depends on its interactions with the environment. Developing countries face more constraints and the environmental interactions seem more complicated. The development process of the semiconductor industry could be better understood with regard to the interactions and social changes. This study proposes a variety-increasing viewpoint based on the concepts of variety increasing and internal learning to analyze the developmental experience of the semiconductor industry in Taiwan. The result shows that the development of Taiwanese semiconductor industry is a continuous variety-increasing process, which is achieved by searching and establishing successful associations in an increasingly wider and complex environment. Implications on the ongoing development of Taiwan's semiconductor industry and the development experiences of other East Asian countries are discussed.     

Are emerging economies less efficient? Performance persistence and the impact of business group affiliation

By drawing a theoretical distinction between the persistence of superior and poor performance, we reconcile the conflicting predictions of the ‘revisionist’ and accepted views on the persistence of firm performance in emerging economies. Using a sample of manufacturing firms in the United States and India, we show that superior firm performance in emerging economies persists only as much as developed economies in line with the revisionist argument. We also provide evidence consistent with the accepted view that poor firm performance persists longer in emerging economies compared to developed economies. Further exploration of the latter shows that, contrary to predictions of extant theories, firms in emerging economies that are affiliated with an MNC or a business group have a greater persistence of poor performance than firms that are unaffiliated with these intermediate governance structures, and hence would be better off operating at arm's length.

A MULTINOMIAL APPROXIMATION FOR AMERICAN OPTION PRICES IN LÉVY PROCESS MODELS

This paper gives a tree-based method for pricing American options in models where the stock price follows a general exponential Lévy process. A multinomial model for approximating the stock price process, which can be viewed as generalizing the binomial model of Cox, Ross, and Rubinstein (1979) for geometric Brownian motion, is developed. Under mild conditions, it is proved that the stock price process and the prices of American-type options on the stock, calculated from the multinomial model, converge to the corresponding prices under the continuous time Lévy process model. Explicit illustrations are given for the variance gamma model and the normal inverse Gaussian process when the option is an American put, but the procedure is applicable to a much wider class of derivatives including some path-dependent options. Our approach overcomes some practical difficulties that have previously been encountered when the Lévy process has infinite activity.
