This paper examines alternative forms of match bias arising from earnings imputation. Wage equation parameters are … imputation match criteria (e.g., union status) are severely biased. Related forms of match bias arise with respect to attributes … used as match criteria, but matched imperfectly. For example, an imperfect match on schooling creates bias that flattens …

Then, we estimate individual … potential income with stochastic earnings frontiers, and we measure overeducation as the ratio between actual income and … potential income. It is shown that the measurement of overeducation by this income ratio is a valuable addition to the …

Economic researchers often consider quotients like R&D investment divided by sales which could be used to measure “research intensity” of firms if available. However, data on research in particular are highly confidential and would not be released in original form. Therefore scientific use...

We use spline interpolation to approximate the subjective cumulative distribution function of an economic agent over the future realization of a continuous (possibly censored) random variable. The method proposed exploits information collected using a small number of probability questions on...

Researchers often form ratios of variables to measure firm characteristics, but which ratios create the most powerful tests? For example, if we use ratios of book value of equity (BE) and market value of equity (ME), or earnings (E) and price (P), does it matter which variable appears in the...

Time-varying risk premia (TVRP) is one of the four sources of stock return autocorrelation. TVRP arises in a securities market equilibrium when the equilibrium expected returns of the available investments vary over time; in particular, the presence of TVRP does not indicate pricing inefficiency....
