We derive the joint density of a Skew Brownian motion, its last visit to the origin, its local and occupation times. The result enables us to obtain explicit analytical formulas for pricing European options under both a two‐valued local volatility model and a displaced diffusion model with constrained volatility. 相似文献

This paper addresses the problem to assess the effect of leverage on the cost of capital for buyout performance analyses. It draws on a unique and proprietary set of data on 133 US buyouts between 1984 and 2004. For each of them, we determine a public market equivalent that matches it with respect to its timing and its systematic risk. We show that under realistic mimicking conditions, the average cost of capital is below the commonly used benchmark S&P 500. Thereby, we control for two important aspects: for the risks taken by lenders in the buyout transactions (which affects the sponsors’ risks), and for the corresponding cost of debt (which lowers the return of the public market equivalent). Only with borrowing and lending at the risk-free rate is the average cost of capital close to the average index return. This finding is particularly important as existing literature on that topic tends to rely on benchmarks without a proper risk-adjustment. 相似文献

Das et al. (2010) develop an elegant framework where an investor selects portfolios within mental accounts but ends up holding an aggregate portfolio on the mean-variance frontier. This investor directly allocates the wealth in each account among available assets. In practice, however, investors often delegate the task of allocating wealth among assets to portfolio managers who seek to beat certain benchmarks. Accordingly, we extend their framework to the case where the investor allocates the wealth in each account among portfolio managers. Our contribution is threefold. First, we provide an analytical characterization of the existence and composition of the optimal portfolios within accounts and the aggregate portfolio. Second, we present conditions under which such portfolios are not on the mean-variance frontier, and conditions under which they are. Third, we show that the aforementioned analytical characterization is also applicable within the framework of Das et al. and thus improves upon their numerical approach. 相似文献

In this paper we apply GMM estimation to assess the relevance of domestic versus external determinants of CPI inflation dynamics
in a sample of OECD countries typically classified as open economies. The analysis is based on a variant of the small open-economy
New Keynesian Phillips Curve derived in Galí and Monacelli (Rev Econ Stud 72:707–734, 2005), where the novel feature is that expectations about fluctuations in the terms of trade enter explicitly. For most countries
in our sample the expected relative change in the terms of trade emerges as the more relevant inflation driver than the contemporaneous
domestic output gap. 相似文献

We consider a dynamic auction environment with a long-lived seller and short-lived buyers mediated by a third party. A mediator has incomplete information about traders’ values and selects an auction mechanism to maximize her expected revenue. We characterize mediator-optimal mechanisms and show that an optimal mechanism has a simple implementation as a Vickrey auction with a reserve price where the seller pays to the mediator only a fixed percentage from the closing price. 相似文献

This paper presents an experiment measuring how lab-induced income inequality affects trust and trustworthiness. Low endowment subjects paired with high endowment subjects showed more trust than subjects in other pairs; this trust was reciprocated with high trustworthiness. 相似文献

Based on the human-capital-theory we analyse the effects of managers’ characteristics on the sportive success of soccer-clubs. Relevant characteristics are a previous career as a player or trainer, an apprenticeship or academic study and the work experience as a manager. Over the last twenty years the proportion of managers with an economic education doubled. This general human capital affects success less complementarily than as a substitutive for sector- or club-specific human capital in terms of a previous career as a player. The work experience as a manager correlates positively with the teams’ league ranking. These results allow recommendations for recruiting new managers. 相似文献

Abstract We provide the first firm‐level evidence of the impact of the trade in producer services (‘offshoring’) on the labour market. Using a new data set from the UK that measures trade in services at the firm level, we find no evidence that importing intermediate services is associated with job losses or greater worker turnover. Using regression to control for observable differences between firms that import service inputs and those that do not, we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not. This seems likely to be the result of positive demand shocks, which cause a simultaneous increase in employment, output, and use of imported service inputs. 相似文献
