The phenomenon of unemployment persistence led to the development of alternative theories of unemployment. Among these the ‘hysteresis’ concept by Blanchard and Summers (1987) received a wide interest. Based on this notion we developed a generalized model that nests Blanchards and Summers' theory. Using this framework we conducted an empirical investigation for the Portuguese labour market (1977–88). The results obtained point towards the existence of labour demand sluggishness, wage inertia and unemployment hysteresis. The model also suggests the existence of a rather inelastic labour demand curve. 相似文献

一个国家名牌出口商品的多少,反映这个国家综合实力的大小,经济竞争力的强弱,以及科学技术发展水平的高低。美国、日本、欧洲一些国家之所以商品出口强势历久不衰,就是由于它们在科学技术的有力支持下,长期以来培育出一大批叫得响、过得硬、受消费者欢迎的名牌商品,并且缘于这些商品而造就出众多赫赫有名、腰缠万贯的大公司、大企业。我国是个发展中国家,虽然改革开放20多年来经济大踏步前进,有了飞跃发展,但与西方经济强国相比,还有相当大的差距。然而,凡事预则立,不预则废。尤其我国入世后,要按照世贸组织的游戏规则开展对外经贸活动,与贸易伙伴 相似文献

A new characterization of the American-style option is proposed under a very general multifactor Markovian and diffusion framework.
The efficiency of the proposed pricing solutions is shown to depend only on the use of a viable valuation method for the corresponding
European-style option and for the transition density of the model’s state variables. Under a Gauss-Markov stochastic interest
rates setup, these new American option pricing solutions are shown to offer a much better accuracy-efficiency trade-off than
the approximations already available in the literature. This result is also used to price callable corporate bonds under an
endogenous bankruptcy structural approach, by decomposing the option to call or default into a European put on the firm value
plus two early exercise premium components. 相似文献

Geographical indications (GI) certify the geographical origins of a product and delineate the specific area in which the certified product must be produced. Despite a large literature on the economics of GIs, few papers have explored the question of the optimal size of GI regions. This note presents a flexible conceptual framework to explore the economics and politics of the delimitation of a GI. The general framework describes the efficiency and distributional effects of the size of a GI and shows how this affects interest groups’ incentives to influence government decision‐making. 相似文献

Abnormal Returns from Takeover Prediction Modelling: Challenges and Suggested Investment Strategies 下载免费PDF全文
Jo Danbolt Antonios Siganos Abongeh Tunyi 《Journal of Business Finance & Accounting》2016,43(1-2):66-97
While takeover targets earn significant abnormal returns, studies tend to find no abnormal returns from investing in predicted takeover targets. In this study, we show that the difficulty of correctly identifying targets ex ante does not fully explain the below‐expected returns to target portfolios. Target prediction models’ inability to optimally time impending takeovers, by taking account of pre‐bid target underperformance and the anticipation of potential targets by other market participants, diminishes but does not eliminate the potential profitability of investing in predicted targets. Importantly, we find that target portfolios are predisposed to underperform, as targets and distressed firms share common firm characteristics, resulting in the misclassification of a disproportionately high number of distressed firms as potential targets. We show that this problem can be mitigated, and significant risk‐adjusted returns can be earned, by screening firms in target portfolios for size, leverage and liquidity. 相似文献

Under the general affine jump-diffusion framework of Duffie et al. [Econometrica, 2000, 68, 1343–1376], this paper proposes an alternative pricing methodology for European-style forward start options that does not require any parallel optimization routine to ensure square integrability. Therefore, the proposed methodology is shown to possess a better accuracy–efficiency trade-off than the usual and more general approach initiated by Hong [Forward Smile and Derivative Pricing. Working paper, UBS, 2004] that is based on the knowledge of the forward characteristic function. Explicit pricing solutions are also offered under the nested jump-diffusion setting proposed by Bakshi et al. [J. Finance, 1997, 52, 2003–2049], which accommodates stochastic volatility and stochastic interest rates, and different integration schemes are numerically tested. 相似文献

We show that firm demand-side factors are strong drivers of procyclical refinancing behavior over the credit cycle using novel data from the Shared National Credit program. Firms are more likely to refinance early when credit conditions are good to keep the effective maturity of their loans long and hedge against having to refinance in tight credit conditions. High credit quality firms are better able to hedge, making their refinancing propensity more sensitive to credit cycles than less creditworthy firms. There is a strong relationship between refinancing a loan, and subsequent growth in capital expenditure, especially when a loan is refinanced early. 相似文献

This article offers a new explanation for unscheduled price cuts and slow adoption of durable goods. We study a standard durable‐good monopoly model with a finite number of buyers and show that this game can have multiple subgame perfect equilibria in addition to the Pacman outcome—including the Coase conjecture. Of particular interest is a class of equilibria where the seller first charges a high price and only lowers that price once some—but not all—high‐valuation buyers purchase. This price structure creates a war of attrition between those buyers, which delays market clearing and rationalizes unscheduled purchase and price cut dates. 相似文献

International transfers to promote the development of countries in the Third World began at the end of the Second World War. At first they were in the form of grants, mostly to colonies or ex-colonies. Then official development assistance from most industrial countries to most developing countries was institutionalized as it became apparent that the international capital market was inadequate in size and too costly for very poor countries. This led to official international lending on increasingly ‘soft’ terms. The ‘softening’ was brought about in a long complex discussion among the lending governments mostly within the Development Assistance Committee of the Organisation for Economic Cooperation and Development Theoretical and practical considerations brought the argument substantially to an end in the late 1970s with the widespread acceptance of the principle that, after all, grants were preferable for the poorest of developing countries. 相似文献
