      abstract = {In this study, we utilize a panel of subnational  district-level yields for corn matched to weather data that  is spatially interpolated from observed weather station  data to identify whether warming impacts exhibit spatial  heterogeneities for both the mean and variance of corn  yields in Ghana. Results are expected to demonstrate that  there exist pertinent regional differences in climate  change impacts. Some of these differences will likely be  attributed to the localized change in climate, while others  will likely be associated with particular agronomic  characteristics (e.g. soil type) that can partially  mitigate (or exacerbate) the effects of warming  temperatures. Climate change impacts on agriculture have  been widely researched in recent years.  In Sub-Saharan  Africa (SSA), many of these studies have focused on  spatially aggregate impacts at the country or higher level,  and typically do not discuss the heterogeneity of  within-region impacts. Thus, there is a growing interest in  more localized climate change impacts that could help  inform regional adaptation within a country. Globally,  climate change is estimated to have adverse effects on crop  yields. With agriculture being the mainstay of many  economies in SSA, it is expected that these economies are  especially vulnerable to climate change. Ghana is one of  the fastest growing economies in SSA (World Bank Report,  2015). Over 20 percent of gross domestic product (GDP) and  two-thirds of agricultural GDP in Ghana are staple crops  and livestock production (OECD Report, 2010). It is  therefore important to quantify the effect of climate  change on crop yields in Ghana. In addition, we explore the  extent to which impacts might vary across different  agronomic regions of the country as this can aid producers  and policy makers in defining potential adaptation  mechanisms.},
