In the last post, we looked at two major non-taxable exchanges: like-kind exchanges and involuntary conversions. In those transactions, any realized gain or loss is generally not recognized at the time of the transaction. Instead, realized gain or loss is deferred until some future point, usually when newly acquired property is ultimately disposed off. This…

Sensitivity Analysis and Dual Simplex Method
Previously, we mentioned that an sensitivity analysis tool called Shadow Price is helpful to evaluate the impact of change when right hand side value of a constraint is increased by 1. However in some cases, there might be new variables or new constraints added, the good news is you don’t have to solve the problem…
Gains, Losses, and Non-Taxable Transactions

Linear Programming Duality
When you are given a linear program, in many cases we call it a primal linear program. It is usually going to be able to find another program, called a dual linear program. The primary reason why we want to use duality is that the computation time of the simplex method is roughly proportional to…
Matrix Presentation of Simplex Method
When it comes to Operations Research, we are mainly talking about optimization problems, so the theories are mainly optimality conditions. They basically mean for an optimization problem, somehow there should be an optimal solution. We want to get the conditions which will make the optimal solution satisfy. Typically we search for the necessary conditions, while…
Hypothesis Testing
Typically we have some question, and that question could be “could the value of the parameter be X?” We could have some idea of what it could be but we’re not sure if that’s correct or not. Then, with that question we use data to try and support that claim or maybe go against that…
Confidence Intervals
We use data to do statistical inference means we either estimate some parameters with confidence, or test some theories or hypothesis about those parameters. Significance Level Consider an example, suppose we have 2 hypothesis: the Null and the Alternative. Also we have come up with a decision rule: after taking an observation of one sample…
Depreciation, Amortization and Depletion
Cost Recovery What is cost recovery? For accounting purposes, businesses must capitalize the cost of assets, if the asset’s useful life is more than one year. Capitalization means that the cost of the asset purchase must show up on the balance sheet rather than as an expense on the income statement. What happens later is…

The person A, who borrowing money, is selling a security (say, treasure bill) to somebody B today and promising to buy it back tomorrow. Repo is collateralized in a sense on both sides:…
