International traders frequently use forward exchange transactions to hedge their cash flows in foreign currencies. A key issue is whether the forward rates are efficiently priced. There is evidence of time-varying risk premia in forward exchange rates. Are these risk premia systematic or unsystematic? This article uses a market model to explain risk, implying that the risk premium in the forward rate varies pari passu with the beta of the return to speculative forward positions. Assuming the unobserved risk premium is proportional to the forward premium allows testing the predicted relations; the data reject the joint hypotheses of the model and systematic risk. In terms of a simple factor model explaining the covariation of the forward premium, the risk premium, and the expected percentage rate of change of the spot exchange rate, the assumption that the forward premium and the risk premium are proportional can be relaxed without changing the empirical results. 相似文献

Using survey forecasts of a large number of Asian, European, and South American emerging market exchange rates, we studied empirically whether evidence of herding or anti‐herding behavior of exchange‐rate forecasters can be detected in the cross‐section of forecasts. Emerging market exchange‐rate forecasts are consistent with herding (anti‐herding) if forecasts are biased towards (away from) the consensus forecast. Our empirical findings provide strong evidence of anti‐herding of emerging market exchange‐rate forecasters. 相似文献

We investigate the number of and reasons for errors and questionable judgments that sell-side equity analysts make in constructing and executing discounted cash flow (DCF) equity valuation models. For a sample of 120 DCF models detailed in reports issued by U.S. brokers in 2012 and 2013, we estimate that analysts make a median of three theory-related and/or execution errors and four questionable economic judgments per DCF. Recalculating analysts’ DCFs after correcting for major errors changes analysts’ mean valuations and target prices by between ?2 and 14 % per error. Based on face-to-face interviews with analysts and those who oversee them, we conclude that analysts’ DCF modeling behavior is semi-sophisticated in the sense that analysts genuinely make mistakes regarding certain aspects of correctly valuing equity but also respond rationally to the incentives they face, particularly the reality that they are not directly compensated for being textbook DCF correct. 相似文献

The article argues that whilst there is a growing sense of degradation and worsening conditions (disaggregation) of work in the cleaning sector in general, there are some important contradictions which require complex organisational responses. In the main, there is a growing sense of isolation in this work, yet also a growing perception of autonomy and workers having to use discretion in new and challenging ways. This article focuses on these issues and management responses to reaggregate the nature of such work, creating new forms of identity and activities intended to enhance (or address) the levels of stability and sustainability at work as well as in operational processes. This management conundrum means that they need to deal with a range of job‐related, skill‐oriented worker learning and also representation issues. These responses bring to the fore the contested nature of such forms of work and how they are changing. 相似文献

The foundational international business (IB) scholarship grappled with whether multinational enterprises (MNEs) are largely efficiency‐enhancing or market‐power inducing institutions. Contemporary scholarship, however, often associates foreign direct investment (FDI) with efficiency‐enhancing properties and thus neglects the market‐power interpretation of the MNE. Such an imbalance is problematic given that the theoretical and empirical justifications behind the field's embrace of the efficiency interpretation are not fully evident. Instead, both efficiency and market‐power effects are seemingly present in cross‐border investment activity. Based on a comprehensive sample of up to 4,361 cross‐border investments materializing between 1986 and 2010, we present theoretically‐grounded hypotheses with regard to when market‐power effects will tend to dominate efficiency effects. We find that cross‐border investments undertaken by emerging‐market MNEs in both developed and emerging markets tend to involve substantial efficiency effects and minimal market‐power effects when compared with the cross‐border investments undertaken by developed‐country MNEs in both developed and emerging markets. 相似文献

Assessing corporate environmental performance (CEP) that is both comprehensive and consistent with sustainable development both for society and companies, while at the same time taking heed of the facts and interests of each stakeholder, is not a simple feat. Due to the multidimensional character of the sustainability concept, several questions must be considered in the evaluation process: (i) the qualitative nature of indicators and the complexity of developing a synthetic index; (ii) the difficulty of choosing properly statistical techniques for aggregation and (iii) the difficulty of introducing stakeholders’ preferences in the assessment models. This paper is an attempt to address this challenge by developing a framework for the assessment of CEP, based on the application of a fuzzy multi‐criterion decision‐making (MCDM) method. To achieve positive scores in a CEP assessment, an organization should be strategically committed and engage in environmental management and governance structures that are translated into good results in terms of both engagement and operational performance. Unless such premises are explicitly incorporated into the assessment criteria, the results would reveal that the CEP measurement could not be brought into a line with an earnest ambition of achieving true sustainable development.

This research analyzes investors’ activity through social media and these media's influence over the Chicago Board Options Exchange Market Volatility Index (VIX) using a logit model and a fuzzy‐set qualitative comparative analysis (fsQCA). The logit results show that social media sentiment influences stock markets. Meanwhile, the fsQCA results show that the investors’ profile is important for explaining how social media influence the stock market. Particularly, holding period combined with experience in technical investors contributes to avoiding a raise in market risk, whereas for nontechnical investors message sentiment and experience form the combination that contributes to avoid a raise in market risk. 相似文献
