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

Abstract There are two explanations for agricultural price dynamics. One follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos. The other stems from the rational expectations tradition of dynamics driven by real shocks. The empirical evidence tends to support the latter, but is not conclusive. The rational expectations model generates an optimal dynamic path from which no improvement can be expected from public intervention. However, if we take account of all the potential market failures in agricultural markets, and especially in developing countries, this conclusion might require some qualifications, although an appropriate policy design for stability has still to be achieved. This paper surveys the positive and normative literature on agricultural prices, highlighting empirical evidence and identifying remaining unresolved issues.  相似文献
