in this study, the profitability of contrarian and momentum strategies were traded in mid- term based on trading volume. the stocks were categorized into three parts (high, middle and low) at the outset. then, the relationship between excess return with three components such as cross-sectional risk, lead-lag effect and time-series pattern were examined based on jegadeesh and titman approach.the...

wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

GRC (Governance, Risk and Compliance) is an umbrella acronym covering the three disciplines of governance, risk management and compliance. The main challenge behind this concept is the integration of these three areas, generally dealt with in silos. At the IT level (IT GRC), some research works have been proposed towards integration. However, the sources used for the construction of the resulti...

A large literature in exchange rate economics has investigated the forecasting performance of empirical exchange rate models using conventional point forecast accuracy criteria. However, in the context of managing exchange rate risk, interest centers on more than just point forecasts. This paper provides a formal evaluation of recent exchange rate models based on the term structure of forward e...

Prior research has shown that people have a tendency to be overly optimistic about future events (i.e., optimism bias) in a variety of settings. In this study, we suggest that optimism bias has significant implications for IT project risk management, as it may cause people to become overly optimistic that they can easily manage project risks. Drawing upon construal level theory (CLT), we invest...

In the standard real options approach to investment under uncertainty, agents formulate optimal policies under the assumptions of risk neutrality or perfect capital markets. However, in most situations, corporate executives face incomplete markets either because they receive compensation packages that restrict their portfolios or because cash flows from the firm’s investment opportunities are n...

A two-sided Weibull is developed to model the conditional financial return distribution, for the purpose of forecasting Value at Risk (VaR) and conditional VaR. A range of conditional return distributions are combined with four volatility specifications to forecast tail risk in four international markets, two exchange rates and one individual asset series, over a four year forecast period that ...

In this paper, we consider the pricing effects of noisy risk disclosure. We show that uncertainty over the riskiness of a firm’s cash flows is priced and that risk disclosure decreases the cost of capital in both single and multi-asset settings. We find that mean and risk disclosure are substitutes, and that firms acquire and disclose more risk information when they discover that risks are high...

The worst-possible Value-at-Risk for a non-decreasing function of dependent risks is known when or the copula of the portfolio is bounded from below. In this paper we analyze the properties of the dependence structures leading to this solution, in particular their form and the implied functional dependence between the marginals. Furthermore, we criticise the assumption of the worst-possible sce...

We show that, as soon there exists a positive bequest motive, sufficiently risk averse individuals should not purchase annuities. This suggests therefore a new explanation for the low level of annuitization, which is valid even if one assumes perfect markets. A model calibration accounting for temporal risk aversion generates an optimal level of annuitization of only 25% of the total savings.
