我们研究了1947年至1998年墨西哥湾石油和天然气勘探技术变革的影响，使用一个独特的微观数据集。构建了一个技术变革指数变量，以反映研究期间离岸产业技术创新的数量和意义。勘探发现和钻井成本的经验模型被用来评估技术变革在油田和区域两级的影响。我们的研究结果表明，在过去的50年里，技术变革在海上工业中发挥了非常重要的作用，增加了储量，降低了成本。虽然在前20年中，耗竭效应占主导地位，但在整个50年的研究期间，技术变革的影响能够抵消资源耗竭的影响。
We examine the impact of technological change on oil and gas exploration in the Gulf of Mexico from 1947 to 1998, using a unique micro-data set. An index variable for technological change is constructed to capture both the number and significance of technological innovations in the offshore industry over the study period. Empirical models of exploration-discovery and of drilling cost are used to assess the effect of technological change at both the field level and the regional level. Our results indicate that technological change played a very significant role in the offshore industry over the past 50 years, increasing reserves and lowering cost. Although depletion effect was dominant over the first two decades, the effect of technological change was able to offset that of resource depletion over the entire 50-year study period.
