在过去的二十年里，巴西的亚马逊和塞拉多生物群落一直受到农业扩张的巨大压力。一种常见的说法是，相关的树木覆盖损失部分是由投机性土地征用造成的。在本文中，我们分析了规划的道路基础设施改善信息和保护政策实施变化对森林转换预期的影响。我们使用了一个独特的土地价格数据集，涵盖了2001年至2012年的时间。基于地租和享乐价值理论，我们认为林地价格传递了预期未来土地利用的信息。我们将林地价格分解为常规林地地租和与林地转换和替代土地利用地租相关的投机部分。然后，我们使用固定效应面板，评估保护政策的变化是否、在哪里以及在多大程度上随着时间的推移影响林地价格。我们的研究结果证实，林地价格包含了林地向农业或牧场转化的预期。我们还发现了巴西土地市场传达了潜在保护政策泄漏信息的迹象，并使用动态毁林热点图对这一猜想进行了描述性探索。
The Brazilian Amazon and Cerrado biomes have been subject to strong pressure from agricultural expansion over the past two decades. A common claim is that the associated tree cover loss was partly driven by speculative land acquisition. In this paper, we analyze the effects of information on planned road infrastructure improvements and changes in conservation policy implementation on expectations of forest conversion. We use a unique land price dataset covering the period from 2001–2012. Based on land rent and hedonic valuation theory, we argue that forestland prices convey information on expected future land use. We decompose forestland prices into a conventional forestland rent and a speculative part related to forestland conversion and alternative land use rents. Using a fixed-effect panel, we then assess whether, where, and to what extent changes in conservation policy affect forestland prices over time. Our results confirm that forestland prices contain expectations about converting forestland to agricultural or pasture land. We also find indications that the Brazilian land market conveys information about potential conservation policy leakage and explore this conjecture descriptively using dynamic deforestation hotspot maps.
