Beggar thy Neighbor? The Transmission of Fiscal Shocks from the US to Canada

This paper investigates how innovations in income taxes and government expenditures originating in the US affect the US economy, and how these effects are transmitted to the Canadian economy. Using a semi-structural VAR model and data for both countries for the 1961:1–2004:3 period, we find that fiscal policy innovations originating in the US are transmitted to the Canadian economy by international trade and capital flows through interest rate and exchange rate channels. Unanticipated shocks to US government expenditures have beggar thy neighbor effects on Canada. US output increases and Canadian output decreases in response to a positive shock to US government expenditures. In response to an unanticipated increase in US income taxes, US output declines while US and Canadian real interest rates rise. The response of Canadian output, however, is not significantly different from zero.

人民币汇率波动对我国出口价格传递效应分析

汇率传递效应不仅影响国内总需求与总供给的均衡．而且还会影响国内货币政策实施的有效性。人民币汇率变动对我国进口价格及其他价格水平的传递程度是决定汇率调节我国贸易收支以及稳定国内物价水平的一个关键因素。本文的目的在于运用协整等方法分析人民币汇率变动对我国出口价格水平的影响,研究结果表明：无论长期内还是短期内,进出口价格对汇率波动的反应都较为敏感,不完全汇率的传递广泛存在于中国的出口企业。

Beyond internal capital markets: The in-house transmission of adverse sales shocks and the collateral channel

We study how shocks to some business segments affect investment in a firm's non-shock segments. We find that subsequent investment in the non-shock segments is significantly lower compared to segments of firms that do not experience shocks. Surprisingly, lower availability of internal funds does not account for the lower investment. We find that segment shocks propagate within the firm by decreasing the value of collateral assets and reducing the availability of external finance. Our results support the operation of an external finance collateral channel ([Kiyotaki, N., Moore, J., 1997. Credit cycles. Journal of Political Economy 105, 211–248.]) previously discussed in the literature.     

中国OFDI技术创新效应的传导机制——基于资本要素市场扭曲视角的分析

本文尝试构建一个中国OFDI(对外直接投资)技术创新效应传导机制理论框架,并对资本要素市场扭曲影响OFDI技术创新效应的作用机制和结果进行拓展分析。研究表明:近年来中国企业OFDI对技术创新具有正向效果,且OFDI企业可以通过从劳动密集型向资本密集型的转型升级、提高管理效率以及生产效率这三个重要途径实现其技术创新能力的跃升;现阶段中国资本要素市场扭曲现象会显著抑制企业OFDI技术创新效应,作用机制是,资本要素市场扭曲作为干扰外部摩擦因子,通过降低企业资本要素密集度和生产效率等渠道抑制企业OFDI技术创新效果。本文进一步提出构建知识产权金融化建议,包含知识产权股权化、知识产权证券化和知识产权流动性机制等内容,以此引导更多金融资源和人力资源参与企业技术创新活动。     

Determinants of time varying co-movements among international stock markets during crisis and non-crisis periods

In this paper, we use the DCC MIDAS approach to assess the validity of the wake-up call hypothesis for developed and emerging markets during the global financial crisis (GFC). We use this approach to decompose the total correlations into short- (daily) and long-run (quarterly) correlations for the period from 1999 to 2011. We then examine the transmission mechanisms by regressing the quarterly economic, financial, and behavioral variables on the quarterly DCC–MIDAS correlations. We find that country specific factors are crisis contingent transmission mechanisms for the co-movements of emerging country pairs and mixed pairs of advanced and emerging countries during the global financial crisis. However, we do not observe wake-up calls in the transmission of the crisis among advanced country pairs. The classification of the transmission mechanisms for crisis and non-crisis periods with the different country pairs has important implications for crisis management as well as for portfolio investment strategies. Thus, our findings contribute to the discussion on the role and effectiveness of the international financial architecture.     

A note on spurious nonlinear regression

This paper explores the power of two tests for nonlinearity against spurious nonlinear regression. Results show that while the BDS test is susceptible to spuriousness, an approach introduced by Peña and Rodriguez [Peña, D. and Rodriguez, J., 2005, Detecting nonlinearity in time series by model selection criteria, International Journal of Forecasting 21, 731–748.] is powerful, regardless of sample size.     

The endo–exo problem in high frequency financial price fluctuations and rejecting criticality

The endo–exo problem lies at the heart of statistical identification in many fields of science, and is often plagued by spurious strong-and-long memory due to improper treatment of trends, shocks and shifts in the data. A class of models that has shown to be useful in discerning exogenous and endogenous activity is the Hawkes process. This class of point processes has enjoyed great recent popularity and rapid development within the quantitative finance literature, with particular focus on the study of market microstructure and high frequency price fluctuations. We show that there are important lessons from older fields like time series and econometrics that should also be applied in financial point process modelling. In particular, we emphasize the importance of appropriately treating trends and shocks for the identification of the strength and length of memory in the system. We exploit the powerful Expectation Maximization algorithm and objective statistical criteria (BIC) to select the flexibility of the deterministic background intensity. With these methods, we strongly reject the hypothesis that the considered financial markets are critical at univariate and bivariate microstructural levels.
