Abstract

We propose new methods to identify the impact of country-specific characteristics, policies, and trade costs on bilateral trade flows within the structural gravity framework. We complement theory with a simple two-stage estimating procedure and offer proof of concept by quantifying the impact of country-specific research and development (R&D) expenditure on trade. Our results suggest a positive relationship overall but a larger impact of R&D on international (versus domestic) trade. Importantly, our methods deliver trade elasticity estimates without the need for price or tariff data, and we highlight this feature by obtaining aggregate and sectoral trade elasticity estimates, including for services.

利用结构引力模型解锁估算国别效应和贸易弹性的新方法

我们提出了新的方法，以确定在结构性重力框架下，国家特征、政策和贸易成本对双边贸易流动的影响。我们用一个简单的两阶段估计程序来补充理论，并通过量化具体国家的研发支出对贸易的影响来证明概念。我们的研究结果表明，总体而言，研发对国际（相对于国内）贸易的影响更大。重要的是，我们的方法在不需要价格或关税数据的情况下提供了贸易弹性估计，我们通过获得包括服务业在内的总体和部门贸易弹性估计来突出这一特点。

期刊介绍： The Journal of Applied Econometrics is an international journal published bi-monthly, plus 1 additional issue (total 7 issues). It aims to publish articles of high quality dealing with the application of existing as well as new econometric techniques to a wide variety of problems in economics and related subjects, covering topics in measurement, estimation, testing, forecasting, and policy analysis. The emphasis is on the careful and rigorous application of econometric techniques and the appropriate interpretation of the results. The economic content of the articles is stressed. A special feature of the Journal is its emphasis on the replicability of results by other researchers. To achieve this aim, authors are expected to make available a complete set of the data used as well as any specialised computer programs employed through a readily accessible medium, preferably in a machine-readable form. The use of microcomputers in applied research and transferability of data is emphasised. The Journal also features occasional sections of short papers re-evaluating previously published papers. The intention of the Journal of Applied Econometrics is to provide an outlet for innovative, quantitative research in economics which cuts across areas of specialisation, involves transferable techniques, and is easily replicable by other researchers. Contributions that introduce statistical methods that are applicable to a variety of economic problems are actively encouraged. The Journal also aims to publish review and survey articles that make recent developments in the field of theoretical and applied econometrics more readily accessible to applied economists in general.
