Exploiting the cointegration properties of the US soy-based market system

Perhaps for the first time, this paper applies Johansen and Juselius' methods of the cointegrated vector autoregression (VAR) model to a monthly US system of markets for soybeans, soy meal, and soy oil. Analysis of the error correction or cointegration space illuminates the empirical nature of policy-relevant market elasticities, and of effects of important policy, market, and institutional events on US soy-related markets. A statistically strong US demand for soybeans emerged as the primary cointegrating relation in the error-correction space.

An Empirical Study on Corporate Governance and Market Valuation in China

This paper empirically studies the relationship between the governance mechanisms and the market valuation of publicly listed firms in China. The authors construct measures for corporate governance mechanisms and measures of market valuation for all publicly listed firms on the two stock markets in China by using data from the firm’s annual reports. They then investigate how the market-valuation variables are affected by the corporate governance variables while controlling for a number of factors commonly considered in market valuation analysis. A corporate governance index is also constructed to summarize the information contained in the corporate governance variables. The index is found to have statistically and economically significant effects on market valuation. The analysis indicates that investors pay a significant premium for well-governed firms in China, benefiting firms that improve their governance mechanisms.

USING THRESHOLD COINTEGRATION TO EXAMINE ASYMMETRIC PRICE ADJUSTMENTS BETWEEN ADR'S AND THEIR UNDERLYING SECURITIES - THE CASE OF TAIWAN

Many recent studies have focused on the relationship between American Depository Receipts (ADRs) and their foreign underlying stocks, because of the price interaction and arbitrage opportunities provided by the dual listings. The cointegration and its corresponding error correction model employed in some recent studies assume that the tendency to move towards a long‐run equilibrium is present all the time. However, the presence of costs of adjustments may prevent economic agents from adjusting continuously. As an extension of previous studies, this paper applies the threshold cointegration model that allows for asymmetric adjustment towards a long‐run equilibrium to inspect the linkage between Taiwanese ADRs and their underlying shares. By employing the threshold error correction model, the short‐term adjustments also are examined. We find some evidence of asymmetric adjustments in our data. The tests for asymmetries are also implemented with the maximum likelihood estimation for the complete multivariate threshold cointegration model instead of the univariate model.     

The beta-binomial convolution model for 2×2 tables with missing cell counts

This paper considers the beta-binomial convolution model for the analysis of 2×2 tables with missing cell counts. We discuss maximum-likelihood (ML) parameter estimation using the expectation–maximization algorithm and study information loss relative to complete data estimators. We also examine bias of the ML estimators of the beta-binomial convolution. The results are illustrated by two example applications.
