Sales recruiting—A major area of underinvestment

How does a firm decide whether the amount now being spent to generate sales force applicants is too much, not enough, or about right? This question can be answered by using information routinely generated by corporate activities and a relatively straight forward decision theory technique. To illustrate that technique, an analysis was conducted for a hypothetical but by no means atypical firm. The results suggest that many corporations could appreciably increase their overall profitability by spending more on sales force recruitment and selection.     

A Comparative Analysis of Auditor, Manager and Financial Analyst Interpretations of SFAS 5 Disclosure Guidelines

This study examines empirically whether financial analysts (users), as well as managers (preparers) and external auditors ascribe different interpretations to the SFAS 5 disclosure criteria. We find: (1) financial analysts are, on average, more conservative than managers and auditors in their numerical interpretations of both the 'remote' and 'probable' verbal phrases; (2) managers and auditors share very similar numerical interpretations of these verbal phrases; (3) audit partners' numerical interpretations of the 'remote' region are between those of managers and users, whereas audit managers align their numerical interpretations with those of managers. One danger is that preparers of financial statements may omit loss contingency information that users consider valuable.     

3G移动通信中的地址分配方案

第三代移动通信包括视频、语音等多种通信业务,在服务质量、服务范围上较第二代移动通信都有了较大进步,很重要的一点就是移动通信网络与IP网络紧密结合在一起,使用统一的网络协议IPV6。网络协议IPV6有海量地址空间等多种特点,适应了3G移动通信向全IP方向发展的要求。在3G移动通信系统中,每一个移动终端可以获得一个全球唯一的IPV6地址,这个地址的分配方法有两个步骤,首先激活PDP,获得一个接口标识,然后进行有状态或者状态的自动地址配置。     

100 YEARS OF TARIFF PROTECTION IN AUSTRALIA

This paper presents time series of tariff rates in Australia from the time of Federation. As a preliminary to the construction of economy-wide series, it constructs series for three broadly representative goods throughout the 100 years: passenger motor vehicles, blankets, and beer. It then constructs two economy-wide series, one for all imports and another for dutiable imports only. It discusses the main events relating to turning points in the series and concludes with some applications.     

Keynesian Inefficiency and Optimal Policy: A New Monetarist Approach

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule neither implies determinacy, nor does it support an efficient outcome. An optimal policy yields an efficient and determinate allocation of resources, but equilibrium policy actions, wages, and prices are indeterminate at the optimum.     

Trust Me! I am a European Central Banker

In the aftermath of the financial crisis, the European Central Bank (ECB) has experienced an unprecedented deterioration in the level of trust. This raises the question as to what factors determine trust in central banking. We use a unique cross‐country data set that includes a rich set of socioeconomic characteristics and supplement it with variables meant to reflect a country's macroeconomic condition. We find that besides individual socioeconomic characteristics, macroeconomic conditions play a crucial role in the trust‐building process. Our results suggest that agents are boundedly rational in the trust‐building process and that current ECB market operations may even be beneficial for trust in the ECB in the long run.     

Is UK Vice Chancellor Pay Justified by University Performance?

The pay of university managers (vice chancellors, VCs) in the UK has risen sharply in recent years. This paper considers the extent to which VC pay awards are related to university performance measures based around institution mission and financial probity using an individual fixed effects strategy based on data covering academic years 1998–99 to 2008–09. In contrast to earlier studies on this theme, we find evidence that VCs are rewarded for observable mission‐based performance measures. Specifically, our results suggest that success in widening participation for students from comprehensive schools and those from areas with low university participation exerts a positive effect on VCs' pay. Securing income flows from university funding council grants also impacts positively on their remuneration. However, even after controlling for a rich array of observable and unobservable factors, there have been sizeable increases in real pay in recent years that cannot be readily explained.

Realized volatility transmission: The role of jumps and leverage effects

This paper is the first to employ a multivariate extension of the LHAR–CJ model for realized volatility of Corsi and Renó (2012) considering continuous and jump volatility components and leverage effects. The model is applied to financial (S&P 500), commodity (WTI crude oil) and forex (US$/EUR) intraday futures data and allows new insights in the transmission mechanisms among these markets. Besides significant leverage effects, we find that the jump components of all considered assets do not contain incremental information for the one-step ahead realized volatility. The volatility of S&P 500 and US$/EUR exchange rate futures exhibits significant spillovers to the realized volatility of WTI. Moreover, decreasing equity prices appear to increase volatility in other markets, while strengthening of the US$ seems to calm down the crude oil market.
