The coexistence of secret intervention operations and “the signaling channel” (Mussa. The Role of Official Intervention, 1981) seems confusing. Vitale ( Journal of International Economics, 49, 1999, 245–267) resolves this puzzle by employing an asymmetric information framework and an assumption of a fundamental‐inconsistent target for the exchange rate. Ferré and Manzano ( International Journal of Finance and Economics, 14, 2009, 378–393) follow Vitale's microstructure framework and argue that the central banks' profitability motivation offers a rationale for their secret intervention even under a target consistent with the fundamentals. However, that the authority uses its superior information to obtain speculative profits through secret intervention in the market is not a typical goal for central banks. To theoretically explain the opaqueness in non‐profitmaking central banks' exchange rate policies, we employ a model of a central bank's optimization by considering that no bank really knows the exact fundamental rate and they take into account the possible bad consequences of announcing the intervention. We also show that, in passing the bank's private information to market participants, a bank's announcement of the intervention size is equivalent to revealing its target rate. (JEL E58, F39)  相似文献

Prior experimental studies on tax evasion generally assume that the budget and the probability of audit are exogenously given, and ignore taxpayers' incentives to detect evasion and their compliance behaviour under such incentives. The experimental evidence of the present paper shows that, on average, subjects are willing to spend 20 to 30% of their tax revenue on auditing. Compliance is also greatly improved if subjects can determine the budget and, hence, the probability of audit. These findings suggest that taking taxpayers' incentives to detect evasion into consideration is important for the design of compliance‐improvement audit schemes.  相似文献

This study solves a location‐then‐price game in which horizontal and vertical differentiation are combined using an asymmetric distribution of consumers’ taste. Boundary locations are robust when the taste disparity of the population is not large and out‐of‐market locations are not allowed. Firms may have incentives to move either inside or outside the market in other situations, so the equilibrium prices are never differentiated. The restrictions of vertical differentiation under this framework are further examined. A model with the entrance of a vertically differentiated product is also discussed.  相似文献

The International Trade Union Confederation was founded in 2006, consisting primarily of former affiliates of the International Confederation of Free Trade Unions and the World Confederation of Labour (although its creation was not formally a merger). I show how changes in the ideologies and identities of both confederations helped to overcome years of mutual antagonism and paved the way for unification. I consider the unification process in the broader perspective of the literature on trade union mergers but stress the need to focus on the role of ideas in such structural changes. The conclusion considers the problems the new confederation faces in developing a common set of ideas and a clear identity out of the separate orientations of its forerunners.  相似文献

This study explores when wholly owned subsidiaries outperform joint ventures with local partners. In order to avoid the endogeneity problem inherent in foreign subsidiaries' operating mode decisions that might confound performance measurement, we employ the propensity score matching method, along with the difference‐in‐differences approach, and compare the performances of joint ventures turned wholly owned subsidiaries vis‐à‐vis continuing joint ventures. Based on foreign subsidiaries' financial data in China for 1998–2006, we find strong evidence that converted wholly owned subsidiaries outperform continuing joint ventures in industries characterized by high levels of intangible assets such as technology or brand, after controlling for factors that may affect the conversion decision. This finding is consistent with the prediction of transaction cost theory. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Drawing on institutional theory and innovation literature, we argue that greater regulatory and normative pressures concerning environmental issues positively influence companies' propensity to engage in environmental innovation. Analysis of environment‐related patents of 326 publicly traded firms from polluting industries in the United States suggests that institutional pressures can trigger such innovation, especially in those firms displaying a greater deficiency gap (i.e., firms polluting relatively more than their industry peers). Moreover, we find that this effect is stronger when asset specificity is high, and that the availability of resources plays different roles depending on the type of pressures (regulatory vs. normative).Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

This study examines the impact of bribery within the home country on firm exports by developing two contrasting hypotheses. On the one hand, preferential treatment resulting from government officials in exchange for bribes may promote exports by enhancing efficiency and enabling bribing firms to better compete in foreign markets. On the other hand, preferential treatment resulting from bribes may decrease exports by providing firms with more established positions within the domestic market diminishing the incentive to explore foreign markets. Adopting the three‐stage least squares method, we test these competing arguments using a sample of firms operating within transition economies. We find that bribery within the home country decreases rather than increases firm exports. The implications of our findings are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

We predict that the media reports on female CEOs as a coherent group, whereas male CEOs are treated as individuals by the media. We also suggest that the resulting investors' perceptions of group entitativity of female‐led firms may not only influence the succession event–performance relationship at the focal firm, but may also have a significant effect on the value of other female‐led companies. Results of a text analysis and an event study of appointments of female CEOs to Fortune 1000 firms provide support for these predictions. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

We propose a new way of constructing more robust technology portfolios to overcome the weaknesses of previous technology portfolios based either on the judgments of experts or on quantitative data such as patents. Instead of using historical data, the method of nonlinear forecasting enables us to forecast the future number of patent citations and accordingly, to use the forecast as a quantitative proxy for future returns and risks of technologies. Using the Black–Litterman portfolio model, we improve the accuracy of inputs by combining the future views of experts with the future returns and risks of technologies. As a consequence of this, the portfolio becomes strongly future‐oriented. With our approach, corporate managers use both experts and data more effectively to build robust technology portfolios. In particular, our method is of great help for companies launching new businesses because the method avoids heavy dependency on internal experts with little knowledge about emerging technologies. A company entering the molecular amplification instrument market is exemplified herein.  相似文献
