An Analysis of the Deposit-taking Market of Hong Kong

This paper analyzes the deposit-takingmarket in Hong Kong prior to the deregulation ofinterest rates in 1994. We argue that bankingregulations, in the forms of branching restrictionsand interest-rate ceilings, had created amonopsonistic market for short-term bank deposits. Asa result, banks in Hong Kong had earned asubstantially wider interest-rate margin than banks inother Asia-Pacific countries and the United States. We provide procedures to estimate the economicsignificance of the foregone interest and find themonopsonistic rent to be in the order of 1% of theGross Domestic Product of Hong Kong for the period1987 through 1994.

Predicting mispricing of initial public offerings

This article investigates the ability of neural network models to predict mispricing of initial public offerings (IPOs). The aim is to improve the modest explanatory power of existing models that are based on the theory of asymmetrically informed economic agents surrounding post‐issue market value of IPOs. This study develops and compares linear regression and neural network models. The results show that modelling variable interactions and non‐linearity allows a potentially fruitful approach for stagging in IPOs. Neural networks have been criticized for being a black box; however, this paper shows that, by using sensitivity analysis, neural networks can provide a reasonable explanation of their predictive behaviour and direction of association between variables.

Contingent Valuation Versus Choice Experiments: Estimating the Benefits of Environmentally Sensitive Areas in Scotland

This paper reports results from a study of the economic value of the conservation benefits of Environmentally Sensitive Areas (ESAs) in Scotland. The main novelty of the approach taken is in comparing two direct valuation methods, namely contingent valuation and choice experiments, to value these benefits. The Contingent Valuation Method (CVM) is well-established as a technique for valuing the sorts of landscape and wildlife enhancements associated with ESAs. The CVM experiment reported here uses a dichotomous choice format, and includes a new correction for part-whole bias. Choice experiments are much less used as an environmental valuation technique. We note several advantages of such experiments over CVM, and then report characteristic values and ‘programme values’ estimated using the method. This application brings to light some problems in applying the choice experiment method. Finally, we discuss the issue of benefits transfer in the context of these two approaches to valuation.     

Border tax adjustments and U.S. trade

This paper reports welfare and terms of trade effects from border adjustments in the indirect taxes used by major U.S. trading partners using a numerical general equilibrium model of world trade and production due to Whalley (1985). Where the United States is a net importer of manufactures (as with Japan and the EEC) the United States gains by having these countries administer taxes on a destination rather than an origin basis. This is because the taxes involved typically have higher rates on manufactured products, and a discriminatory origin basis tax with higher rates on exportables operates akin to an export tax.
