We often face investment decisions, whether in our personal lives or our jobs. Investment projects involve payments at different times in a project's life. Capital costs are usually paid at early stages, but revenue is generated in the future. Time affects the value of money, and these values can't be compared directly. In EME 460, Geo-Resources Evaluation and Investment Analysis, we will learn methods to evaluate investment projects. The objective of the course is to ensure students learn the techniques used in geo-resource project evaluation, cash flow, net present value, and rate of return analysis; benefit cost ratio and payback period; interest rate and break even calculations; tax considerations, mutually exclusive projects evaluation, uncertainty and risks, depreciation, and loan calculations.

Principles of Macroeconomics 2e covers the scope and sequence of most introductory economics courses. The text includes many current examples, which are handled in a politically equitable way. The outcome is a balanced approach to the theory and application of economics concepts. The second edition has been thoroughly revised to increase clarity, update data and current event impacts, and incorporate the feedback from many reviewers and adopters. Changes made in Principles of Macroeconomics 2e are described in the preface and the transition guide to help instructors transition to the second edition. The first edition of Principles of Macroeconomics by OpenStax is available in web view here.
