On tariffs and smuggling

The purpose of this paper is to show that if a country wants to eliminate smuggling, it may have to increase rather than decrease the tariff. This paradoxical case could take place if the country in question is large and the foreign elasticity of demand for imports is inelastic.     

An Evaluation of the Actuarial structure of manitoba crop Insurance Program and its Implications

Very little research has been done in evaluating the basic principles and assumptions of the actuarial structure for premium ratemaking in crop insurance programs. Therefore, the objectives of this study are: (a) to examine the Pearson probability distribution of actual crop yields as compared with an application of normal-curve theory to crop yields as compared with an application of normal-curve theory to crop yield distributions and in turn to crop insurance ratemaking which was suggested by Botts and Boles in 1958 [1]; (b) to evaluate the pure premium rates derived from estimated Pearson probability distributions for wheat yields in 14 crop districts of the province of Manitoba; and to establish an experience rating system for the crop insurance program based upon the estimated Pearson distribution of actual crop yields on the individual farm.     

A note on customs unions vs. non-preferential tariffs

It has been shown by Cooper and Massell [1965] that making a non-preferential tariff reduction is always superior to joining a customs union. The purpose of this paper is to show that if the country concerned is a large country, then joining a customs union is not necessarily inferior to making a non-preferential tariff reduction.     

Relating management practices to job characteristics of R&D: The case of Taiwan

Based on a study of researchers in three major R&D industries in Taiwan, this article found that while both supportive and directive styles of management are important in the supervision of R&D processes, the supportive behavior seems to be more effective than the directive strategy in motivating research professionals at work. Data also indicated that the job characteristics of R&D may be significantly influenced by industrial conditions. The management differences between industries are explained in the features peculiar to each particular industry. Implications of the findings for enhancing the management effect are also discussed.The author is an Associate Professor, Department of Business Administration, National Cheng-Kung University, Tainan, Taiwan, R.O.C.

A Comparative Evaluation of Yield Risk Reductions with Alternative Crop Insurance Programs in Manitoba

Three crop insurance programs are evaluated in terms of their effectiveness of yield risk reductions for 371 Manitoba farms. The examination is first conducted with a proposed index method, with which the relative yield risk reduction magnitude is calculated and compared for each farm under each alternative program. The generalized stochastic dominance (GSD) methodology is also used to provide an alternative analytical framework in analyzing producers’relative preferences among those alternatives by comparing the net yield distributions generated by each program for each farm. The results suggest that, given an actuarially sound basis, the filly individualized crop insurance (FI) program is the most favorable choice for risk-averse producers. The area coverage and individual indemnity program (IA) is generally the second best option. The full area crop insurance program (FA) is least preferred by risk-averse farmers.     

Will Japan,Taiwan or the US be isolated by China? A macroeconomic game approach

In Taiwan, Japan and even the United States, economic isolation has become a major concern due to the growing Chinese economy, which may lead to welfare losses for the isolated countries. On the basis of the framework developed by Plasmans et al. [Plasmans, J., Engwerda, J., van Aarle, B., Di Bartolomeo, G., Michalak, T., 2005. Dynamic Modelling of Monetary and Fiscal Cooperation Among Nations. Springer], this paper establishes a four-player game with an open-loop information structure to measure possible losses by an international policy coordination approach instead of the conventional free trade agreements. We simulate macroeconomic adjustments of the four countries according to the different institutional scenarios and economic shocks. The baseline simulation and sensitivity analyses indicate that Taiwan can get benefit by participating in coalitional mechanisms including China. In addition, most of the feasible policy coalitions cannot come into effect without US participation. This implies that at the current stage the US rather than China should be the main economic partner of Taiwan and Japan to prevent them from being economically marginalized.     

Tenure Security and Long‐term Investment on Tenanted Land: Evidence from Colonial Taiwan

We use farm diary data from Taiwan in the 1920s and 1930s to estimate the impacts of a state‐wide tenancy reform on tenants’ investment in the farmland and production outcome. The reform, commencing in 1922, enhanced the tenure security for the tenants by promoting written contracts that extended tenure length from 1 year to 5–6 years, and by establishing government‐sponsored organizations for dispute settlements. Our estimations rely on a difference‐in‐difference framework, where self‐cultivated farms are used as the control group. We find that the reform encouraged tenants to make investments in the irrigation and drainage system of the farms, which is expected to have long‐lasting benefits for production. The improved irrigation/drainage system led to significant efficiency gains for the farms. In contrast, the reform did not affect tenants’ usage of fertilizer much, which benefits production for only a crop season or a year.     

Hedging derivative securities with genetic programming

One of the most recent applications of GP to finance is to use genetic programming to derive option pricing formulas. Earlier studies take the Black–Scholes model as the true model and use the artificial data generated by it to train and to test GP. The aim of this paper is to provide some initial evidence of the empirical relevance of GP to option pricing. By using the real data from S&P 500 index options, we train and test our GP by distinguishing the case in-the-money from the case out-of-the-money. Unlike most empirical studies, we do not evaluate the performance of GP in terms of its pricing accuracy. Instead, the derived GP tree is compared with the Black–Scholes model in its capability to hedge. To do so, a notion of tracking error is taken as the performance measure. Based on the post-sample performance, it is found that in approximately 20% of the 97 test paths GP has a lower tracking error than the Black–Scholes formula. We further compare our result with the ones obtained by radial basis functions and multilayer perceptrons and one-stage GP. Copyright © 1999 John Wiley & Sons, Ltd.
