Derivative pricing using multivariate affine generalized hyperbolic distributions

In this paper we use multivariate affine generalized hyperbolic (MAGH) distributions, introduced by Schmidt et al. (2006), to show how to price multidimensional derivatives when the underlying asset follows a MAGH distribution. We also illustrate the approach using market data from the BOVESPA (São Paulo Stock Exchange) and the exchange rate of the Brazilian Real vs. US Dollar to price some multidimensional derivatives.     

A STATE‐LEVEL ANALYSIS OF BUSINESS CYCLE ASYMMETRY

This paper provides a comprehensive examination of asymmetry in US state‐level business cycles. We consider two different types of asymmetry in the adjustment process of a stationary time series: deepness and steepness. The data used in the study are a comparable set of state‐level coincident indexes (SCIs) developed by the Federal Reserve Bank of Philadelphia. Specifically, results from using the momentum‐threshold autoregressive model provide evidence of asymmetry in the growth rate of 23 SCIs as well as the equivalent national coincident index.

Inter-industry Technology Spillover Effects in China： Evidence from 35 Industrial Sectors

The present paper calculates 35 industrial sectors’ similarity matrices for the period of 1997-2008 using China’s input-output tables for 1997,2002 and 2007,and uses these to measure inter-industry technology spillover to analyze the spillover effects on industrial sectors’ labor productivity.The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry.The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R&D input,but also increases over time.We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is,on average,greater than that between the four categories,indicating that technology spillover occurs more easily between similar industries.This research shows that the interindustry technology spillover effect in China has begun to increase,and the government should take advantage of this effect.     

EXPERIMENTAL EVIDENCE ON ENGLISH AUCTIONS: ORAL OUTCRY VERSUS CLOCK

This paper tests experimentally, in a common value setting, the equivalence between the Japanese English auction (or clock auction) and an oral outcry auction where bidders are allowed to call their own bids. We find that (i) bidding behaviour is different in each type of auction, but also that (ii) this difference in bidding behaviour does not affect significantly the auction prices. This lends some support to the equivalence between these two types of auction. The winner's curse is present: overbidding led to higher than expected prices (under Nash bidding strategies) in both types of auction. Although interesting and encouraging, the results clearly indicate that further research is necessary, particularly with a modified experimental design.

以电雷管为试验对象,对不同浓度的C3H7NO3气体对电雷管密封性能的影响进行了试验研究。建立了C3H7NO3-密封胶扩散模型,对C3H7NO3气体在密封胶中的扩散进行了分析,结果表明:密封胶的腐蚀速度与C3H7NO3气体的浓度成正比。     

The effect of IMF lending on the probability of sovereign debt crises

This paper explores empirically how the adoption of IMF programs affects sovereign risk over the medium term. We find that IMF programs significantly increase the probability of subsequent sovereign defaults by approximately 1.5–2 percentage points. These results cannot be attributed to endogeneity bias as they are supported by specifications that explain sovereign defaults and program participation simultaneously. Furthermore, IMF programs turn out to be especially detrimental to fiscal solvency when the Fund distributes its resources to countries whose economic fundamentals are already weak. Our evidence is therefore consistent with the hypothesis that debtor moral hazard is most likely to occur in these circumstances. Other explanations that point to the effects of debt dilution and the possibility of IMF triggered debt runs, however, are also possible.     

General equilibrium with heterogeneous participants and discrete consumption times

The paper investigates the term structure of interest rates imposed by equilibrium in a production economy consisting of participants with heterogeneous preferences. Consumption is restricted to an arbitrary number of discrete times. The paper contains an exact solution to market equilibrium and provides an explicit constructive algorithm for determining the state price density process. The convergence of the algorithm is proven. Interest rates and their behavior are given as a function of economic variables.     

Signalling,Disclosure And The Implications Of Financial Structure For Uk Corporate R&D ∗

This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure.
