In a laboratory experiment we show that minimum wages have significant and lasting effects on subjects' reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects' reservation wages which persists even after the minimum wage has been removed. Firms are therefore forced to pay higher wages after the removal of the minimum wage than before its introduction. As a consequence, the employment effects of removing the minimum wage are significantly smaller than are the effects of its introduction. The impact of minimum wages on reservation wages may also explain the anomalously low utilization of subminimum wages if employers are given the opportunity to pay less than a minimum wage previously introduced. It may further explain why employers often increase workers' wages after an increase in the minimum wage by an amount exceeding that necessary for compliance with the higher minimum. At a more general level, our results suggest that economic policy may affect people's behavior by shaping the perception of what is a fair transaction and by creating entitlement effects.

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: under heteroskedasticity, the parameters of log-linearized models estimated by OLS lead to biased estimates of the true elasticities. We explain why this problem arises and propose an appropriate estimator. Our criticism of conventional practices and the proposed solution extend to a broad range of applications where log-linearized equations are estimated. We develop the argument using one particular illustration, the gravity equation for trade. We find significant differences between estimates obtained with the proposed estimator and those obtained with the traditional method.

We conduct the first robust study of the oldest known form of technical analysis, candlestick charting. Candlestick technical analysis is a short-term timing technique that generates signals based on the relationship between open, high, low, and close prices. Using an extension of the bootstrap methodology, which allows for the generation of random open, high, low and close prices, we find that candlestick trading strategies do not have value for Dow Jones Industrial Average (DJIA) stocks. This is further evidence that this market is informationally efficient.

This study investigates auditor-provided tax services from 2000 to 2002, during which fees paid to auditors for nonaudit services (NAS) were disclosed, but separate disclosure of tax service fees was voluntary. We examine changes in the market for tax NAS in 2002, as Congress debated possible prohibition of these services. Using the Heckman MLE procedure to control for selection bias in tax fee disclosure, we find that a strong pre-2002 positive association between tax fees and higher than expected audit fees weakened significantly in 2002, suggesting that some companies paying high audit fees reduced or terminated auditor-provided tax services in 2002. Our findings also suggest that auditor-provided tax services were reduced among new or short-tenure clients. Controlling for tax complexity, we also find some evidence that early “returns” (i.e., tax rate reductions) to companies from auditorprovided tax services were reduced in 2002. Finally, results of our selection model imply that the decision to voluntarily disclose fees paid to the auditor for tax services is positively associated with tax complexity and auditor tenure, and negatively associated with the proportion of NAS fees to total fees. Overall, our findings imply significant change in auditor-provided tax services prior to 2003, when separate disclosure of auditor-provided tax service fees was mandated.

This study examines how accounting quality relates to firm-level capital investment efficiency. Our first hypothesis is that higher quality accounting enhances investment efficiency by reducing information asymmetry between managers and outside suppliers of capital. Our second hypothesis is that this effect should be stronger in economies where financing is largely provided through arm's-length transactions compared with countries where creditors supply more capital. Our results are consistent with these hypotheses both across and within countries. They are robust to alternative econometric specifications, different measures of accounting quality and investment-cash flow sensitivity, and numerous control variables.

We link farmland values to climatic, soil, and socioeconomic variables for U.S. counties east of the 100th meridian, the historical boundary of agriculture not primarily dependent on irrigation. Degree days, a nonlinear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield, gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust, and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become quite large under scenarios involving sustained heavy use of fossil fuels.

Recent research provides evidence that the operating cash flows-to-price ratio subsumes accruals in explaining future annual returns. This suggests that the accrual anomaly is part of the overall value-glamour anomaly and does not represent the mispricing of earnings. We extend the literature by using multiple measures of abnormal accruals and separate analyses of future annual returns and future earnings announcement returns. The results reveal that the operating cash flows-to-price ratio does not subsume abnormal accruals in explaining future annual returns or future announcement returns. We also find that the operating cash flows-to-price ratio does not subsume total accruals in explaining future announcement returns. These results are not consistent with accruals being a manifestation of the value-glamour anomaly. Our study contributes to the current debate on the existence and the extent of the (abnormal) accrual anomaly. Moreover, the methodology employed can help researchers in exploring mispricing phenomena.

In a democracy, a political majority can influence both the corporate governance structure and the return to human and financial capital. We argue that when financial wealth is sufficiently concentrated, there is political support for high labor rents and a strong governance role for banks or large investors. The model is consistent with the “great reversal” phenomenon in the first half of the twentieth century. We offer evidence that in several financially developed countries a financially weakened middle class became concerned about labor income risk associated with free markets and supported a more corporatist financial system.
