While conducting measurements in experiments, there are generally two different types of errors: random (or chance) errors and systematic (or biased) errors. Every measurement has an inherent uncertainty. We therefore need to give some indication of the reliability of measurements and the uncertainties of the results calculated from these. biases in using customs unit value indices to measure export and import price changes. Yet, unit value proxies are still used because they are by-products of existing customs administration systems and have relatively low incremental cost compared with the price surveys of establishments needed for narrow specification prices. Repeated measurements often yield different values for the same quantity. What is the accuracy of a measurement and which instrument is the precise one? Let's answer these questions and wander into the realm of measurements. Unit Values for Import and Export Price Indexes - A Proof of Concept Don Fast, Susan Fleck. NBER Working Paper No. Issued in October NBER Program(s):International Trade and Investment The U.S. Bureau of Labor Statistics’ import and export price indexes (MXPI) are published from an ever decreasing sample relative to the size of trade.

2. Unit Value Indices A. Introduction Export and import price indices (XMPIs) are compiled by three general methods, the nature of which is largely dependant on the source data used. The first and predominant method,1 in terms of the number of countries using it, uses unit value indices compiled from detailed import and export merchandise trade data derived from . Forget proxy lists, use endpoints. We thought long and hard about how we could improve the age-old proxy list. With us, you no longer need to import any proxy lists because all you need is a single endpoint (think of it as an address:port configuration) that assigns a pre-checked proxy to your connection automatically. The quality-adjusted relative export prices are obtained from equation (18) and import prices from equation (19), where we replace the c.i.f. price appearing there by the tariff-inclusive c.i.f. unit value, as in equation (20), and the f.o.b. price by the f.o.b. unit value. Each of these are then aggregated over partner countries, and from.   While import taxes are easier to levy, there is increasingly more evidence that importers engage in trade tax evasion. The literature uses, trade gap, the difference between reports from the two ends of a trade link, as a proxy for illegal imports. Many papers have found a robust positive correlation between import tax rates and the trade gap.

In some countries a Paasche price index based on unit values is compiled as a proxy for a true Paasche (or Laspeyres) price index on the basis of prices. This is for example the case in German foreign trade statistics. Unit values are average prices referring to a 'commodity number' (CN), that is an aggregate of (more or less homogeneous) commodities .

Wang presents a methodology to study implied cost of capital's (ICC) measurement errors, which are relatively unstudied empirically despite ICCs' popularity as proxies of expected returns.
