Using data of twin students graduating from junior high schools between 2002 and 2004 in Taiwan, we estimate the effects of peers on high school joint entrance examination performance. To alleviate the potential endogeneity of peer educational achievement, linear models with twin fixed effect and instrumental variables are estimated. Quantile, quantile with twin fixed effect and quantile with instrument variables regressions are also implemented to determine whether estimated peer effects differ at various locations of the testing scores’ conditional distributions. Positive and statistically significant peer effects are found to exist at the mean and at different quantile levels. 相似文献

We explore how the informational frictions underlying monetary exchange affect international exchange rate dynamics. Our perfectly flexible price model is capable of producing endogenously rigid international relative prices in response to technology and monetary shocks. The model is capable of accounting for the empirical regularities that the real and nominal exchange rates are more volatile than U.S. output, and that the two are positively and perfectly correlated. The model is also consistent with other standard real business cycle facts for the United States. 相似文献

We propose a new way of constructing more robust technology portfolios to overcome the weaknesses of previous technology portfolios based either on the judgments of experts or on quantitative data such as patents. Instead of using historical data, the method of nonlinear forecasting enables us to forecast the future number of patent citations and accordingly, to use the forecast as a quantitative proxy for future returns and risks of technologies. Using the Black–Litterman portfolio model, we improve the accuracy of inputs by combining the future views of experts with the future returns and risks of technologies. As a consequence of this, the portfolio becomes strongly future‐oriented. With our approach, corporate managers use both experts and data more effectively to build robust technology portfolios. In particular, our method is of great help for companies launching new businesses because the method avoids heavy dependency on internal experts with little knowledge about emerging technologies. A company entering the molecular amplification instrument market is exemplified herein. 相似文献

The European Emission Trading Scheme (EU‐ETS) has chosen to adopt an auctioning procedure to initially allocate CO2 emission permits. Free allocation of permits will become an exception for the third phase (2013–2020) and most firms will have to buy all their permits on the market or via auctions. The ability of bidders to collude is a key concern about the design of the auction format. To counter collusion, the auction can be open to bidders without compliance obligations (speculators). This paper aims at studying experimentally speculation as a collusion‐breaking device in two different auction mechanisms: the uniform‐price sealed‐bid auction and the ascending clock auction. Our results suggest that a uniform sealed‐bid auction open to speculators should be chosen from a revenue maximization point of view. In this mechanism, compliance agents adopt an aggressive strategy toward speculators. This strategy significantly increases the seller's revenue, compared to the more collusive clock auction. In the latter, on the contrary, bidders accommodate speculators, letting them buy permits in the auction and buying their necessary permits on the secondary market. However, as opening the auction to speculators deteriorates efficiency, the regulator faces a trade‐off between these two objectives. 相似文献

We describe a double agency problem in firms' charitable donations. When managers have better knowledge about the effectiveness of donations and their altruistic preferences, it is difficult for shareholders to tell whether charitable donations are made for a strategic purpose or due to managerial altruism. We characterize the equilibrium donations in a heterogeneous competition model. We show that managerial altruism is a substitute for the effectiveness of donations, and excess donations cannot be prevented by a compensation scheme that reduces the interest conflicts between ownership and management. Under board authorization, the board will tolerate donations with high effectiveness and low altruism as well as donations corresponding to low effectiveness and high altruism. Under a penalty scheme, the altruistic manager will increase donations, in order to increase donation's strategic benefit to compensate for the loss from the penalty.

We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods. 相似文献

我国投资者会听话听音吗?文章利用文本分析方法,基于我国上市公司2005-2012年年度业绩说明会上的管理层语调数据对此进行了实证检验。研究发现,投资者对管理层的净正面语调做出了显著的正向反应,尤其是对负面语调做出了显著的负向反应。这表明在我国强调“意会”的语境文化背景下,投资者会听话听音,管理层语调具有信息含量,上市公司的业绩说明会具有其自身的存在价值。文章的研究结果还意味着,“词袋”方法及其构建的管理层语调用词列表在我国儒家文化背景下具有一定的适用性,值得开展进一步的研究。 相似文献

This paper proposes a semiparametric smooth coefficient cost model to study the university cost structure where coefficients are an unknown function of the university's overall quality. A local least square method with a kernel weight function is used to estimate the cost function, and a simple statistic for testing a parametric model of the additive quality versus the semiparametric smooth coefficient model is applied. Empirical results from 56 universities in Taiwan show that, taking quality into account, higher education is subject to diseconomies of scale. In all categories—comprehensive and science/technology and public and private universities—the current university scale in Taiwan is too big to be cost efficient. (JEL I21, H52, 9120) 相似文献
