The gender pay gap is an important issue today in the U.S. The lack of transparency surrounding pay in businesses is viewed as one cause of this gap. The first section of this article explores the origins of the gender pay gap and presents a brief history of pay transparency. Then, I propose a framework built from three continua that breaks the concept of pay transparency into types and levels. Using this framework, I offer guidance to organizations that want to increase pay transparency. The article concludes with a discussion of the risks associated with increased pay transparency and suggestions for future research.  相似文献

This study investigates whether and how the accounting ratios of peer firms within the same industry (the industry peers) or firms within the industry of their customers (the downstream peers) help improve the predictability of sample firm financial distress. We document that the Z‐score factors of the companies with high correlation in stock returns help predict financial distress. The results show that accounting‐based ratios of the industry peers and the downstream peers enhance the accuracy of early warnings of financial distress, especially when prior returns of peer firms are highly correlated with the sample firm.  相似文献

Although a large literature argues that European settlement outside of Europe during colonization had an enduring effect on economic development, researchers have been unable to assess these predictions directly because of an absence of data on colonial European settlement. We construct a new database on the European share of the population during colonization and examine its association with economic development today. We find a strong, positive relation between current income per capita and colonial European settlement that is robust to controlling for the current proportion of the population of European descent, as well as many other country characteristics. The results suggest that any adverse effects of extractive institutions associated with small European settlements were, even at low levels of colonial European settlement, more than offset by other things that Europeans brought, such as human capital and technology.  相似文献

Replacement brood cows are among the most significant investments for cow-calf operations, thus crucial to profitability. Many cow-calf producers find it cost effective to purchase replacements from a reliable replacement heifer seller, though by doing so they increase risk of reproductive inefficiency due to unknown characteristics of the heifers. When important information about a product is missing to buyers, a seller can build a reputation over time that acts as signal for quality. Previous work has explored reputation effects in feeder cattle markets, but to our knowledge we are the first to explore reputation effects in bred replacement cattle markets. Using data from an annual replacement heifer sale, we analyze the values of heifer characteristics and test for premiums from reputation development. After controlling for reproductive practices, breed, and other characteristics, we find reputation does not play the role that Shapiro theorized. In this sale, the lot order is strategically chosen and may indicate bred heifer quality to buyers, replacing the need for reputation as a signal. This study highlights the importance of quality signals and regional preferences in bred replacement cattle marketing and lays the empirical groundwork for future studies to test Shapiro's theory.  相似文献

ABSTRACT

Since the 1950s, we have known that the presence of zero-valued dependent variables can seriously bias econometric estimates whether the zeros are included or excluded. Yet the widely-used gravity model is frequently estimated on samples that include large fractions of zeros. An influential paper by Santos Silva and Tenreyro – based on simulations that include no economically-determined zeros – concludes that the bias problems resulting from zeros and those resulting from heteroscedasticity and nonlinearity can be solved using the Poisson Pseudo-Maximum-Likelihood (PPML) model including the zero values. This paper begins by adapting the Santos Silva and Tenreyro experimental design to include economically-determined zeros to see whether this conclusion continues to hold. With this design, it finds that alternative estimators have lower bias than PPML. Changing to a Monte Carlo design that replicates the much-higher real-world frequency of predicted values near zero restores the finding of lower bias with the PPML estimator. The results highlight the need for very careful design of Monte Carlo experiments when evaluating alternative estimators of the gravity model.  相似文献

In light of the Schumpeterian paradigm, this article explores the rise of the tax state in eleventh‐century China and its further transition towards a fiscal state until the Mongol conquest in 1279. By the late eleventh century in the Song dynasty, two‐thirds of state revenues came from taxing non‐agricultural sectors, especially from the collection of excise. The Song state became the first sustainable tax state in global history, as manifested in three major aspects: monetization; indirect taxation; and centralization and professionalization in the tax administration. The boundary of the Song tax state was largely confined to urban settlements. In rural areas, the state gave up the collection of commercial taxes by farming out this right to local elites. In the twelfth century, as traditional tax revenues fell far short of supporting military defence, the Song administration utilized credit instruments. Around 1200, the amount of redeemable promissory notes first exceeded that of annual tax revenues. This shift from tax‐based public finance to credit‐based public finance completed the transition towards a fiscal state. Nonetheless, this development in the fiscal state was still at an early stage and proved to be unstable. Toward the end of the Southern Song, hyperinflation caused by the over‐issuance of promissory notes seriously threatened the economy.  相似文献
