This paper focuses on developing countries’ pioneer exports to the OECD and obtains several important results on export dynamics, linking export experience and export survival. Using product level data at the SITC 5-digit level for 114 developing countries over the 1962–2009 period, we show that prior export experience obtained in non-OECD markets significantly increases survival of pioneer exports toward the OECD. The experience does not need to last long, as gaining experience for more than two years does not confer any additional benefit. The effect of experience depreciates rapidly with time: a break in export experience prior to entering the OECD reduces the advantage on survival. Finally, the role of prior export experience is particularly relevant for survival in the first two years upon entry into the OECD. The geographic dynamic of export experience reveals that experience is acquired in neighboring, easy to access markets before reaching more distant, richer partners and ultimately serving the OECD with a higher probability of survival. 相似文献

This paper applies the DSGE‐VAR methodology to assess the size of fiscal multipliers in the data and the relative contributions of two transmission mechanisms of government spending shocks, namely hand‐to‐mouth consumers and Edgeworth complementarity. Econometric experiments show that a DSGE model with Edgeworth complementarity is a better representation of the transmission mechanism of fiscal policy as it yields dynamic responses close to those obtained with the flexible DSGE‐VAR model (i.e. an impact output multiplier larger than one and a crowding‐in of private consumption). The estimated share of hand‐to‐mouth consumers is too small to replicate the positive response of private consumption. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

Co-monotonicity of optimal investments and the design of structured financial products 总被引:1,自引:0,他引:1
Marc Oliver Rieger 《Finance and Stochastics》2011,15(1):27-55
We prove that, under very weak conditions, optimal financial products on complete markets are co-monotone with the reversed
state price density. Optimality is meant in the sense of the maximization of an arbitrary preference model, e.g., expected
utility theory or prospect theory. The proof is based on a result from transport theory. We apply the general result to specific
situations, in particular the case of a market described by the Capital Asset Pricing Model or the Black–Scholes model, where
we derive a generalization of the two-fund-separation theorem and give an extension to APT factor models and structured products
with several underlyings. We use our results to derive a new approach to optimization in wealth management, based on a direct
optimization of the return distribution of the portfolio. In particular, we show that optimal products can (essentially) be
written as monotonic functions of the market return. We provide existence and nonexistence results for optimal products in
this framework. Finally we apply our results to the study of bonus certificates, show that they are not optimal, and construct
a cheaper product yielding the same return distribution. 相似文献

ON VALUING STOCHASTIC PERPETUITIES USING NEW LONG HORIZON STOCK PRICE MODELS DISTINGUISHING BOOMS,BUSTS, AND BALANCED MARKETS

For longer horizons, assuming no dividend distributions, models for discounted stock prices in balanced markets are formulated as conditional expectations of nontrivial terminal random variables defined at infinity. Observing that extant models fail to have this property, new models are proposed. The new concept of a balanced market proposed here permits a distinction between such markets and unduly optimistic or pessimistic ones. A tractable example is developed and termed the discounted variance gamma model. Calibrations to market data provide empirical support. Additionally, procedures are presented for the valuation of path dependent stochastic perpetuities. Evidence is provided for long dated equity linked claims paying coupon for time spent by equity above a lower barrier, being underpriced by extant models relative to the new discounted ones. Given the popularity of such claims, the resulting mispricing could possibly take some corrections. Furthermore for these new discounted models, implied volatility curves do not flatten out at the larger maturities. 相似文献

This article explores host–guest dynamics at Sólheimar eco-village, Iceland to contribute to the conceptualization of transformative learning in volunteer tourism. At the eco-village, the host and volunteers come together to share similar goals and meaningful experiences. This interaction gets complicated, however: the eco-village exists within the global capitalist system and must operate using market norms. The idealist and educational expectations of the volunteers often clash with the practical short-term goals of the community: there are also cultural and experiential differences between the parties. This clash is used to discuss the importance of sincerity in volunteer tourism at the eco-village. Data were collected through fieldwork, primarily including participant observations and interviews, to help interpret the patterns of behaviors and perceptions of both parties in relation to the aim. Ultimately, the experience that binds host and guests cannot solely be about learning to do things alternatively and sustainably; it requires sincerity, using Taylor's 2001 sincerity concept, to tackle the difficulties in working alternatively and sustainably to attain this experience. It is argued that transformative learning during the volunteer experience in alternative spaces should be conceptualized to include the promotion of sincere encounters, and adjusted to concern both the host and its guests. 相似文献

The objective of this study is to analyse investors’ perceptions of sponsorship’s ability to increase brand equity, through the impact of sponsorship announcement on stock market value. An event study method, based on a unique sample of 293 worldwide sponsorship announcements from 2010, shows substantial negative abnormal returns following announcement dates. In addition, a cross-sectional regression analysis reveals the influence of several featured factors. Philanthropic sponsorships and sponsorships of events with distinctive values are less negatively perceived by investors, but US companies exhibit more negative returns in shareholder value than other firms. This study offers no support for varying impacts of event audience, renewal agreement, property sponsorship and title sponsorship on abnormal returns though. 相似文献
