An Inelastic Demand Curve for Stocks
ثبت نشده
چکیده
In 2005 and 2006, the split-share structure reform converted the nontradable shares of most domestic public firms in China to tradable shares. This conversion imparted a drastic supply shock to the public market. Studying this unique event, we provide direct evidence to support an inelastic demand curve for stocks. Abnormal returns of the sample firms resulting from the reform are found to be negatively associated with the size of the supply shock. This finding is free from the confounding information effects present in many prior studies of stock price elasticity. It is also robust after controlling for opposite price impacts of ROA, firm size, and ownership concentration.

In present study, the effects of optimization on seismic energy spectra including input energy, damping energy and yielding hysteretic energy are parametrically discussed. To this end, 12 generic steel moment-resisting frames having fundamental periods ranging from 0.3 to 3s are optimized by using uniform damage and deformation approaches subjected to a series of 40 non-pule strong ground motio...
متن کاملEffects of daily morphine administration and deprivation on choice and demand for remifentanil and cocaine in rhesus monkeys.
Choice procedures have indicated that the relative reinforcing effectiveness of opioid drugs increases during opioid withdrawal. The demand curve, an absolute measure of reinforcer value, has not been applied to this question. The present study assessed whether mild morphine withdrawal would increase demand for or choice of remifentanil or cocaine. Four rhesus monkeys chose between remifentanil...
متن کاملDemand Response Based Model for Optimal Decision Making for Distribution Networks
In this paper, a heuristic mathematical model for optimal decision-making of a Distribution Company (DisCo) is proposed that employs demand response (DR) programs in order to participate in a day-ahead market, taking into account elastic and inelastic load models. The proposed model is an extended responsive load modeling that is based on price elasticity and customers’ incentives in which they...
متن کاملDid BSE affect demand for beef in Canada? An Application of the Quadratic Almost Ideal Demand System∗
A quarterly, weakly-separable, Quadratic, Almost Ideal Demand System is estimated for beef, pork and chicken in Canada. The restrictions that would lead to the less flexible AIDS model were rejected at the five per cent level. Results for the first stage model indicated that demand for the meat group is inelastic, with an own-price elasticity of -0.24. Demand for beef in Canada was inelastic du...
