STRATEGIC MANDATORY LABELING OF BIOTECHNOLOGY PRODUCTS IN THE ABSENCE OF QUALITY DIFFERENCE

This article examines the strategic use of mandatory labeling of biotechnology products, such as genetically modified food. A foreign dominant firm produces a biotechnology product and foreign competitive firms produce a conventional one. It is shown that if other trade measures such as tariffs are also available, the government of an importing country may impose mandatory labeling even in the case where there is no quality difference between biotechnology and conventional products. A combination of a discriminatory tariff on the biotechnology product and mandatory labeling shifts rents from the foreign dominant firm to the domestic economy.     

Patent citations, technology diffusion, and international trade: evidence from Asian countries

In this paper, we examine international technology diffusion by using patent citations as a proxy for technology diffusion. We focus on some Asian economies, i.e., Korea, Taiwan, China and India, to investigate the relationship between technology diffusion and their trade experience with the U.S., Japan, and other G7 countries. Our empirical results reveal that trade specialization has a significant correlation with technology diffusion. Some policy implications are discussed.     

Tariff Revenue Competition in a Free Trade Area: The Case of Asymmetric Large Countries

The striking result has been shown by Richardson that tariff revenue competition between two symmetric member countries of a free trade area (FTA) results in complete elimination of external tariffs if there exists a pure‐strategy Nash equilibrium at all. Richardson also conjectures without building a model that if member countries are asymmetric in market size, there exists a pure‐strategy Nash equilibrium in which both countries set positive external tariffs. We explicitly extend his tariff competition model into the case of asymmetric FTA member countries, and confirm his conjecture. We also show that there exists a mixed‐strategy Nash equilibrium in the case of symmetric countries.     

International trade and renewable resources under asymmetries of resource abundance and resource management

This paper examines the interaction between relative resource abundance and resource management regimes in determining trade patterns and gains from trade in a two-country model with a renewable resource. A model developed by Brander and Taylor [Brander JA, Taylor MS (1997b) Resour Energy Econ 19:267–297] is extended. It is shown that relative resource abundance determines trade patterns if resource abundance is similar in both countries and the relative demand for the resource good is moderate, or if resource abundance is sufficiently different and the relative demand is not so high. Otherwise, a difference in resource management regimes determines trade patterns. Even under an open-access regime, the resource-scarce country gains from trade unless resource abundance is similar and the relative demand is low.      

Asymptotic expansions of the distributions of the estimates of coefficients in a simultaneous equation system

In this paper asymptotic expansions are derived for the density functions of the TSLS and LIML estimates of coefficients in a simultaneous equation system when the sample size increases and the effect of the exogenous variables increases along the sample size. These approximations are used to compare the asymptotic moments of the TSLS and LIML estimates and the concentration of probability around the true value of the estimates.     

Pricing Options under Stochastic Interest Rates: A New Approach

We will generalize the Black-Scholes option pricing formula by incorporating stochastic interest rates. Although the existing literature has obtained some formulae for stock options under stochastic interest rates, the closed-form solutions have been known only under the Gaussian (Merton type) interest rate processes. We will show that an explicit solution, which is an extended Black-Scholes formula under stochastic interest rates in certain asymptotic sense, can be obtained by extending the asymptotic expansion approach when the interest rate volatility is small. This method, called the small-disturbance asymptotics for Itô processes, has recently been developed by Kunitomo and Takahashi (1995, 1998) and Takahashi (1997). We found that the extended Black-Scholes formula is decomposed into the original Black-Scholes formula under the deterministic interest rates and the adjustment term driven by the volatility of interest rates. We will illustrate the numerical accuracy of our new formula by using the Cox–Ingersoll–Ross model for the interest rates.     

Is the Government Failure Theory Still Relevant? A panel analysis using US state level data

Abstract The purpose of this paper is to empirically examine the robustness of the government failure theory. A core feature of the government failure theory is demand heterogeneity. Previous studies have brought into question the robustness of the government failure theory, due to inconsistent results concerning the explanatory power of demand heterogeneity. Therefore, in this paper we revisit this important research agenda using US state level panel data. We find the two‐way fixed effects model a suitable model for testing the government failure theory's robustness and present findings which indicate that observable demand heterogeneity has a positive effect on the size of the nonprofit sector. This paper also empirically examines the relevance of the complementary financing hypothesis in terms of the cooperative nature of the governmental and nonprofit sector relationship; that is where governments delegate the production of quasi‐public goods to the nonprofit sector.     

International Knowledge Flows and Productivity: Intra- vs. Inter-Industry Spillovers

The effects of international knowledge spillovers on total factor productivity (TFP) at the industry level are examined by using a panel of 13 manufacturing industries across 15 OECD countries over 23 years. We distinguish between intra- and inter-industry spillovers from the information on patent applications and citations. Patent data are taken from the Japan Patent Office and the United States Patent and Trademark Office. Using four alternative spatial panel estimation techniques, we find that international knowledge spillovers within the same industry significantly contribute to sectoral TFP. In contrast, there is little evidence of a positive effect of international knowledge spillovers on TFP across industries.
