Sources of professional staff turnover in public accounting firms revealed by the exit interview

Employee and employer stated reasons for leaving public accounting were studied together with the conditions surrounding departure and the best and least liked qualities of CPA firm work. Data collected after employee terminations on selected aspects of the work was shown to be a good predictor of whether employees left of their own volition or at the request of the firm and revealed several areas suitable for improving personnel relationship and reducing professional staff turnover.

On the basis of estimates of four input translog production and cost functions using data for Irish manufacturing, different inferences are obtained about price elasticities and the elasticities of substitution between inputs, indicating sensitivity to the primal or dual representation of the technology. the results strongly reinforce the findings of Burgees (1975) and Appelbaum (1978) from U.S. data.     

Measuring portfolio performance and the empirical content of asset pricing models

Recent work by Richard Roll has challenged the worth of portfolio performance measures based on the capital asset pricing model. This paper demonstrates that Roll's conclusions are due to his focusing on a ‘truly’ ex-ante efficient index. Using a choice and information theoretic framework, we show that an appropriate index is efficient relative to the probabilities assessed by the ‘market’. Residual analyses and portfolio performance tests, using such an index, yield meaningful results for a wide class of information structures. Roll's primary criticisms, however, relate to tests of the asset pricing model itself. We argue that these criticisms are vastly overstated.     

Conceptual Displacement: From the Natural to the Social

This paper distinguishes between epistemological naturalism, which it supports, and ontological naturalism, which it opposes. It sketches the emergence of anti-naturalist social theory among nineteenth-century African-American intellectuals and its refinement by twentieth-century feminists. These movements challenged ontological naturalism in the social sciences by substituting social constructionist concepts of race and gender for naturalist ones. Economics awaits a similar liberation. The paper identifies four naturalist concepts—atomism, determinism and biologically determined race and gender differences—as structuring mainstream economic theory. It concludes that ontological naturalism is inconsistent with the application of the epistemology of the natural sciences to the social sciences.     

Learning with noiseless information and payoff-relevant signals

Summary. In models of active learning or experimentation, agents modify their actions to affect the distribution of a signal that provides information about future payoffs. A standard result in the experimentation literature is that agents experiment, if at all, to increase information. This finding is a direct consequence of Blackwell's theorem: one experiment is more informative than another if and only if all expected utility maximizers prefer to observe the first. Blackwell's theorem presupposes, however, that the observed signal only conveys information and does not directly affect future payoffs. Often, however, signals are directly payoff relevant, a phenomenon that we call signal dependence. For example, if a firm is uncertain about its demand and uses today's sales as a signal of tomorrow's demand, then that signal may also directly affect tomorrow's profit if the good is durable or if consumers form consumption habits. Datta, Mirman and Schlee [9] and Bertocchi and Spagat [4] show that, if the signal is payoff relevant, experimentation may indeed reduce information. Here we show that, despite the inapplicability of Blackwell's Theorem, agents always experiment to increase information if the information structure is noiseless: given the true value of the unknown parameter, the signal realization is deterministic. We then apply our framework to analyze Lazear's [16] model of retail clearance sales, a model with both signal dependence and noiseless information.
