Presents a method for estimating the impact on national development of installation of telecommunication facilities in rural areas of developing countries. A methodology developed by Hardy is applied to three groups of developing countries and a hypothetical rural region to estimate the impact on GDP per thin route satellite earth station installed over a ten year period. A logarithmic relationship between telephone density and impact on GDP per earth station is found, so that the impact per earth station increases with lower telephone densities. The model can be used to estimate the impact on national GDP of telephone installations and/or thin route earth stations in regions of low telephone density.  相似文献

Non-linear SUR and ITSUR techniques are proposed for the estimation of the APT and the CAPM when the factors are observed. These techniques estimate all of the parameters of the model simultaneously and directly impose the model's non-linear parameter restrictions.  相似文献

We empirically capture boardroom backscratching, or cronyism, as when a firm's Chief Executive Officer (CEO) and directors concurrently receive excessive remuneration. We argue that boardroom backscratching can inhibit a board's constructive criticism and monitoring, resulting in a greater likelihood of bad news hoarding. Using 14,104 US firm-year observations spanning 1999–2020, we document a significant positive relationship between boardroom backscratching and stock price crash risk. In additional analyses, we show that boardroom backscratching firms produce less readable annual reports and engage in greater upward real earnings management as channels for concealing bad news. We also find that external monitoring mechanisms weaken the positive association between boardroom backscratching and stock price crash risk. Our main findings withstand several endogeneity tests including propensity score matching, entropy balancing, difference-in-differences analysis using firms’ commencement of boardroom backscratching and CEO turnover event analysis. Our study offers insights to securities regulators and policymakers to revisit the notion of board independence, develop relevant market oversight and revise director and executive remuneration disclosure requirements so as to mitigate adverse stock market performance associated with boardroom backscratching.  相似文献

Sovereign wealth funds have become a prominent feature of the international financial landscape. However, legitimate concerns have been raised about these funds. Many of those concerns can be addressed via increased accountability and transparency by the funds. The Santiago Principles are a good start in doing so. My sovereign wealth funds scoreboard points to areas where these Principles can be improved. At the same time, the OECD effort to address concerns from the host‐country side has not resulted in the erection of new barriers to that form of cross‐border investment, but the OECD failed to reverse the creeping financial protectionism of the past decade. Because of their size and the source of their funding, some Asian funds stand out. As a result, those funds will be held to a higher standard of accountability and transparency.  相似文献
