This paper uses stamp catalogue prices to investigate the returns on British collectible postage stamps over the period 1900–2008. We find an annualized return on stamps of 7.0% in nominal terms, or 2.9% in real terms. These returns are higher than those on bonds but below those on equities. The volatility of stamp prices approaches that of equities. Stamp returns are impacted by movements in the equity market, but the systematic risk of stamps remains low. Stamps partially hedge against unanticipated inflation. Estimates of average after-cost returns for individual investors show that stamps may rival equities in terms of realized performance. 相似文献

In rural areas of less developed countries because of market imperfections, the health and nutritional status of peasants may directly depend on the production levels of specific agricultural goods rather than solely on income levels. This channel of health and nutrition determination has never been studied. 相似文献

When-issued trading concerns transactions in securities that have not yet been issued. This paper investigates the Dutch “grey
market” for when-issued shares prior to stock splits, using a unique hand-collected data set. Market makers are more likely
to set up a when-issued market when the underlying firm is larger, the relative trading volume of the stock is higher, and
the stock return is less volatile. The when-issued securities trade at a small premium over the regular shares during the
weeks prior to the stock split, but this when-issued premium disappears in the last days of trading. 相似文献

This study develops and tests a comprehensive framework that explains what, when, and how CEO characteristics influence firms’ innovation outcomes in R&D-intensive industries. Empirical evidence from 109 CEOs from 87 U.S.-based pharmaceutical firms over the period 2001–2013 reveals that research-oriented CEOs – those with ability and motivation for science and technology – increase their firms’ innovation outcomes. The results indicate that the CEO–innovation relationship strongly depends on the extent of CEOs’ managerial discretion, which is shaped by the organizational context. We contribute to a more comprehensive understanding of the role of CEOs in firms´ innovation performance differentials. 相似文献

Using Danish longitudinal data with information about wealth for a sample of first‐time house buyers and their parents, we test whether there are direct financial transfers from parents to children in connection with the house purchase, or in connection with unemployment spells occurring just after the purchase, when children typically hold few liquid assets. First, we document that child and parent financial resources are correlated. Then, we introduce conditioning variables and exploit the panel aspect of the data to also condition on fixed unobserved factors, which arguably govern preferences and/or productivity. We find no evidence of direct financial transfers. 相似文献

In a simple model of a frictionless financial market with rational agents, the value of private information increases when
large discrete shocks independently affect the fundamental value of the asset and the exogenous trading. The complementarity
in information gathering generates multiple equilibria. 相似文献

We introduce a new methodology to target direct transfers against poverty. Our method is based on estimation methods that focus on the poor. Using data from Tunisia, we estimate ‘focused’ transfer schemes that highly improve anti‐poverty targeting performances. Post‐transfer poverty can be substantially reduced with the new estimation method. For example, a one‐third reduction in poverty severity from proxy‐means test transfer schemes based on OLS method to focused transfer schemes requires only a few hours of computer work based on methods available on popular statistical packages. Finally, the obtained levels of undercoverage of the poor are particularly low. 相似文献

This note examines the investment performance of diamonds and other gems (sapphires, rubies, and emeralds) over the period 1999–2010, using a novel data set of auction transactions. Over our time frame, the annualized real USD returns for white and colored diamonds equaled 6.4% and 2.9%, respectively. Since 2003, the average returns have been 10.0%, 5.5%, and 6.8% for white diamonds, colored diamonds, and other gems, respectively. Both white and colored diamonds outperformed stocks between 1999 and 2010. Nevertheless, gem returns covary positively with stock returns, underlining the importance of wealth-induced demand for luxury consumption in collectibles markets. 相似文献
