The contribution of this article is to present an investment process that allows the asset manager to limit risk exposure to macro-factors – including expectations on correlation dynamics – whilst allowing for selective exposure to risk factors using factor-portfolios that emulate the risk and return profile of market micro-factors. The design of the process provides the ability to explicitely limit risk exposures to macro-factors based on forward-looking narratives allowing the investor to reflect – in the resulting active allocation – expectations of financial or systemic crises by, say, restricting the overall exposure to the credit macro-factor that includes the risk factor exposures (micro-level) arising, for example, from corporate and supranational spreads whilst simultaneously increasing the exposure to flight-to-safety macro-factors under a local or global crisis. This process is better suited to drawdown-averse investors that are willing to forgo some upside in order to effectively limit significant portfolio losses from crises, systemic or otherwise. In order to improve the optimization over the rugged solution space resulting from superimposing macro-factors' risk envelopes on the factor-portfolios' tracking error allocation, a genetic-algorithm-based optimization is proposed.

The present research examined the possibility that subtle face‐like features (a smile‐ or a frown‐like line) on a product can influence evaluations of and preferences for that product. The same within‐participants experiment was conducted twice, once in the United Kingdom and once in Colombia: participants viewed four variants (concave [smile‐like] line, convex [frown‐like] line, straight line, line absent) of three different products (tea, shampoo, juice) and both evaluated the products on visual analogue scales and completed a forced choice decision task. The results revealed a general tendency across scales, products, and countries for the participants to rate products more positively and to choose products more frequently when they displayed a concave line relative to a convex line; comparisons with the straight line and absent line conditions suggested that the effects were present for both concave and convex lines, but were stronger in the concave instance. These findings provide both a deeper theoretical understanding of the influence of subtle cues on evaluation and decision making, and concrete, practical information for both product designers and marketers.  相似文献

The globalization process together with the extraordinary growth in the use of Internet offer firms new growth opportunities. Retail firms are using a multichannel approach, involving the Internet, in their internationalization strategies. Website traffic as measured by unique users and online awareness is among the measures for assessing the success of the online channel. There is little evidence, however, linking website traffic and the characteristics of the retail multichannel internationalization process. In order to fill this gap, this paper analyses the factors explaining the retailer's international website traffic. Website traffic data for a sample of European fashion apparel retailers are modelled as dependent on characteristics of the organization and of its physical and virtual internationalization strategy. Following the results of several linear regression models, we infer the complementarity of online and offline channels in the international operation, as well as the contribution of social networks as traffic generators.  相似文献

This article examines the effect of bank credit on employment formalization in Uruguay. Using a difference-in-differences methodology the article finds that financial deepening decreases informality, especially in more financially dependent sectors. In addition, the effect is found to be greater among women and older workers. In the period under analysis the economy underwent a severe economic crisis and bank credit contracted sharply, but we find no evidence that the effect of bank credit on employment formality changed over time.  相似文献

This paper studies whether domestic macroprudential policy may attenuate the inward transmission of monetary policy shocks from the United States to domestic bank lending growth in three emerging market economies—Chile, Mexico, and Russia. Identification relies on banks’ heterogeneous exposure to prudential policies and the fact that foreign monetary policy shocks are exogenous from the perspective of these economies. After analyzing the effects of the aggregate domestic prudential policy stance, we focus on specific prudential policies targeting mortgage and consumer loans, as well as foreign‐currency deposits. Although our overall results are mixed, we find evidence that the strength of international monetary policy spillovers varies depending on the stance of domestic macroprudential policy. In particular, a tighter reserve requirement stance over foreign‐currency deposits in Chile dampens the effect of an international monetary policy shock on domestic local‐currency lending, but reinforces that on foreign‐currency lending, whereas in Russia, it dampens the effect on both local‐currency and foreign‐currency lending, although to different degrees. Prudential policies targeting the asset side of banks’ balance sheets, such as mortgage loans or consumer credit, are found to amplify international monetary policy spillovers in some cases and attenuate it in others, depending on the country context.  相似文献

In this paper, we explore the conditions of entry‐timing advantages in renewable natural resource industries. Drawing from behavioural theory of the firm, we classify firms in two groups depending on the different heuristics used to make entry decisions when facing the cyclical endogenous nature of these industries: crowd firms are procyclical, making decisions based on the current phase of the industry cycle, whereas anti‐crowd firms follow a countercyclical strategy, making uncertain, and risky decisions by estimation of the next phase of the cycle. Therefore, anti‐crowd firms anticipate the deployment of resources each cycle, potentially gaining entry‐timing advantages beyond those provided by traditional competitive isolating mechanisms. Through a mathematical simulation of a performance feedback model, we reveal that the entry‐timing advantage of the anti‐crowd group becomes possible when the rivalry in the industry and the price sensitivity of competitors are high, and when the time required to deploy the resources is short.  相似文献

Using data from financial and economic performance of International Oil Companies (IOCs) in the exploration-extraction (E&E) business, along with institutional and market orientation of governments and National Oil Companies (NOCs) that receive project offers, the international E&E market is analyzed in both institutional development and behavioral patterns of type of E&E contract following an agency theory approach. Additionally, given Mexico's recent energy reform being launched between 2015 and next 2019, the various types of E&E contracts are analyzed, comparing license contracts with production sharing and risk service ones. Next, using panel data methods an analysis of 17 enterprises between 2005 and 2015 is presented, where so-called global IOCs show higher returns and commitment than specialized ones, demonstrated by their net income and return on equity, or ROE.  相似文献

Using administrative records of births from the Perinatal Surveillance System of the Peruvian Social Security System (ESSALUD), we test whether high admissions of pregnant women affected non-elective caesarean section (C-section) rates in the ESSALUD public hospitals during 2005–2006. We present a basic theoretical model that considers physician preferences for leisure and hospital capacity constraints, and test the model predictions. We find that physician demand for leisure increases the probability of C-sections in small and medium-size hospitals, while hospital capacity constraints set a limit on them. We discuss the policy implications as well as the policies implemented to avoid unnecessary C-sections.  相似文献

In this article, we contribute to the understanding of the role that external risk perceptions play in decisions regarding the combination of company-owned and franchised units in the hospitality industry, and to knowledge of the impact of specific CEO characteristics on perceptions of environmental uncertainty. We examine the effects of tenure, an entrepreneurial nature and the innovative attitude of the CEO on the perception of external risk, and address the direct and indirect consequences of such perceptions of external risk on the configuration of the network of outlets. Our results show a significant relationship between the characteristics of the CEO and the perception of risk but, contrary to expectations, risk perception is associated with a lower degree of franchised outlets within the ownership mix.  相似文献
