The relationship between stock prices and exchange rates in South Africa and Nigeria: structural breaks analysis

The relationship between stock prices and exchange rates has continued to generate interest from both the academia and financial industry players for many years. This study conducts an empirical investigation into the relationship between stock prices and exchange rates for the two largest economies in Sub-Saharan Africa – South Africa and Nigeria. Our methodology accounts for structural breaks in the data and the long-run relationship between stock and foreign exchange markets. The results of multivariate causality tests with structural breaks showed that causality runs from exchange rates to domestic stock prices in Nigeria (flow channel) while in South Africa, no causality exists between domestic stock prices and exchange rates. The results also reveal that there is causality from the London stock market to both countries’ stock markets, thus showing that international stock markets are driving both the Nigerian and South African stock markets.     

Information in stock prices: the case of the 2016 U.S. presidential election

On the day before the 2016 U.S. presidential election, the odds of Hillary Clinton winning the presidency, according to political prediction markets, were above 90%. Surprisingly, Donald Trump won the Electoral College handily. In this study, we examine how movements in specific stock prices foreshadowed the eventual outcome. Specifically, we conduct a series of standard event-study tests focused on pharmaceutical companies, which became a focal point during the presidential campaign. Results show that while stocks of pharmaceutical companies significantly underperformed the market prior to the election, prices substantially increased beginning three days before the election outcome. This increase is both statistically significant and economically meaningful and robust to various event-study methodologies. These results suggest that some sectors of the stock market seemed to anticipate the election outcome.     

Cyclicality of commodity markets with respect to the U.S. economic policy uncertainty based on granger causality in quantiles

Given the importance of the U.S. in global commodity markets, the goal is to explore whether U.S. economic policy uncertainty impacts the price performance of certain commodities. The analysis uses the Granger causality in quantiles method that allows us to test whether there are different effects under different market conditions. The results document that economic uncertainty impacts the returns on the commodities considered, with the effects clustering around the tail of their conditional distribution. Robust evidence was obtained under alternative definitions of uncertainty.     

Macroeconomic uncertainty,growth and inflation in the Eurozone: a causal approach

In this article, we evaluate the causal relationship between macroeconomic uncertainty indices, inflation and growth rate for 17 Eurozone countries on a county-level examination. In performing a series of linear and nonlinear causality tests, we find little evidence of a causal relationship between uncertainty and macroeconomic variables. Thus, macroeconomic analysis based on uncertainty indices should be treated with caution.     

直接投资引致的美中贸易逆差:经验研究

运用基于误差修正模型的格兰杰因果关系检验模型,在商品分类层面研究关中贸易逆差与关国对华直接投资的内在联系。结果显示：从长期和短期来看,中国制成品的出口都是关中贸易逆差的“因”,中国制成品的出口与关国对华直接投资之间具有显著的双向格兰杰因果关系,因此关国进入中国的FDI,尤其是进入制造业的FDI越多,美中贸易逆差就越大;美中贸易逆差是结构性的,它不仅不会在短期内消除,而且会随着美国劳动密集型产业向中国的进一步转移而加剧。     

Safe havens in the face of Presidential election uncertainty: A comparison between Bitcoin,oil and precious metals

Even though the empirical literature on safe haven properties of different assets with respect to financial risks is increasing, their abilities to safeguard against political risks has not been the subject of large empirical investigations. This paper uses an Empirical Mode Decomposition-based approach to look into the time-varying role of different assets (in particular, oil, precious metals and Bitcoin) as a safe haven against U.S. stocks in times of heightened uncertainty surrounding the outcome of the 2016 U.S. presidential election. Our results suggest that oil can act as an effective safe haven against political risk exposure; but such property varies over time. The abilities of gold and silver to provide positive returns during downturns have been also documented in the medium-and the long-term. Bitcoin also serves as a safe haven against U.S. stock losses but in the short-term. These findings provide useful and relevant information to investors to help ensure better asset allocation in an uncertain environment.     

美中贸易收支与人民币汇率关系:实证分析

针对美中贸易收支与人民币汇率问题,经研究发现,汇率变动对贸易收支的影响是值得怀疑的,仅仅依靠人民币汇率变动是无法解决美中贸易逆差问题的。1994—2002年年度数据实证显示,美中贸易收支与人民币汇率(名义或实际汇率)之间没有稳定的关系;1998—2003年月度数据计量表明,美中贸易收支与人民币汇率之间没有长期稳定的协整关系。并且,依据美中两国月度统计数据计量的结论是相一致的。因此,“人民币升值论”或许更多的是基于政治而非经济因素,人民币汇率浮动并不能解决美中贸易逆差问题。     

Oil windfall,public spending and price stability: modelling inflation in Chad

This article examines the determinants of inflation in Chad using quarterly data from 1983:Q1 to 2009:Q3. The analysis is based on a single-equation model, completed by a Structural Vector Autoregression (SVAR) model to capture inflation persistence. The results show that the main determinants of inflation in Chad are rainfall, foreign prices, exchange rate movements and particularly public spending, which soared following the onset of oil production in 2003. The effects of rainfall shocks and changes in foreign prices on inflation persist during six quarters. Changes in public spending and the nominal exchange rate affect inflation during three and four quarters, respectively.     

Financial development and relationship evolvement among money supply,economic growth and inflation: a comparative study from the U.S. and China

With the rapid development of financial markets, economic financialization degree can no longer be ignored for its influence on the relationship among money supply, economic growth and inflation. Combined with the horizontal comparison of China, this article concentrates on the financial development and evolution from the period of industrialization to economic financialization in the U.S., systematic and comprehensive analysis is first done on the variation of overall economic operation. Then impulse response function based on VAR model is applied to study the dynamic influence of economic financialization degree on the relationship evolvement. The empirical results show that economic financialization makes good explanation of the deviating phenomenon among money supply, economic growth and inflation, and the interactive relationship between fictitious economy and real economy is becoming closer and closer. Furthermore, compared to the U.S., China still belongs to the process of transforming from the period of industrialization to economic financialization.     

Asymmetric interest rate pass-through in the U.S., the U.K. and Australia: New evidence from selected individual banks

This paper provides new evidence on asymmetric interest rate pass-through in the U.S., the U.K. and the Australian economies by using the Nonlinear Auto-Regressive Distributed Lag model, central bank interest rates, lending and deposit interest rates from selected banks, spanning the period 2000–2013. The results provide evidence that corroborates the asymmetric pass-through market predictions. Robustness tests are also performed by splitting the sample period into that prior to and after the recent financial crisis. The new findings document that the asymmetric character of pass-through remains active only in the case of Australia.     

Dynamic lobbying: Evidence from foreign lobbying in the U.S. Congress

How do interest groups decide which member of Congress to target when decisions are made collectively? Do lobbying strategies change as legislation advances? Answering these questions is challenging due to a lack of systematic observations of lobbying contacts. I answer these questions using a novel data set constructed from reports submitted by lobbyists on behalf of South Korea regarding its free trade agreement with the United States for 10 years. I show that a diverse set of politicians are contacted but the timing, intensity, and strategy of lobbying contacts vary by politicians' institutional positions as well as their predisposed preferences for free trade.     

Dynamics of volatility transmission between the U.S. and the Chinese agricultural futures markets

The U.S. and China are two of the biggest players in the world agricultural market. The literature documents that volatility in the U.S. agricultural futures market spills over significantly to that of China. This article provides further insights into the spillovers from China to the U.S. as well as the time horizon and dynamics of the bidirectional spillovers through the application of a multivariate extension of the heterogeneous autoregressive model, in relation to four commodities – soybean, wheat, corn and sugar. The results confirm the existence of significant spillovers from the U.S. to China for four commodities, which are primarily generated by the shorter-term volatility components in the U.S., and provide evidence for the increasing pricing power of the Chinese market. The findings are robust against various specifications and have important investment and policy implications.     

Changes in the relationship between short‐term interest rate,inflation and growth: evidence from the UK, 1820–2014

This paper examines the dynamic relationship between interest rates, inflation and economic growth using a long dataset for the UK. The approach adopted enables us to identify structural breaks in the dynamic system (vector autoregression (VAR)). We find interest rates respond much more strongly to growth and inflation over recent decades, and forecast error variance decomposition analysis indicates there is increasing interconnectedness between the variables in recent years. Economic policymakers need to carefully monitor the linkages between these variables and be prepared to adjust their monetary policy tools when faced with structural changes.     

The price relationship between organic and non-organic vegetables in the U.S.: evidence from Nielsen scanner data

This study investigates price relationships between organic and conventional carrots, tomatoes, and lettuce in the U.S. utilizing Nielsen scanner data from 2006–2015. We employ a threshold vector error correction model (TVECM), threshold vector autoregressive model (TVAR), and threshold cointegration test to test whether market integration exists between organic and conventional vegetables as well as the existence of asymmetric price transmission. The results find positive long-run relationships between organic and conventional prices of carrots and tomatoes and show the existence of asymmetric price transmission in price pairs of lettuce and tomatoes. Our findings suggest that the price relationship between organic and conventional vegetables varies by characteristics, such as shelf life, volatility in the price premium, and substitutability.     

Trade liberalization in the presence of domestic regulations: public policies applied to EU and U.S. wine markets

Wine is the highest valued product in the agricultural, food, and beverage sector traded between the United States and the European Union (EU) and wine faces a range of tariffs that are differentiated by country and product category. In addition, the production of wine grapes is heavily regulated within the EU and there are complicated state-level policies in the United States designed to limit the retail availability of wine. There continues to be economic and political pressure for reform to the tariffs between the United States and the EU, and to the domestic regulations in each region. We carefully develop parameters to characterize the effects of tariffs and domestic regulations that affect production and consumption of wine in the two regions. Simulation results show that reductions in tariffs would have relatively small effects in EU and U.S. wine markets, whereas reductions in EU domestic policies that affect wine grape production would have much larger trade and welfare implications.

U.S. policy in the euro crisis and the institutional deepening of the monetary union

ABSTRACT

Theoretical approaches to European integration often downplay and sometimes ignore the role of external actors. But the regime complex through which the euro crisis of 2010-2015 was prosecuted involved the United states directly and indirectly through the IMF. Tracing such external involvement shows that, although they preferred greater deepening of euro area institutions than was achieved, U.S. and IMF officials nonetheless contributed substantially to the creation of the EFSF/ESM, robust ECB action and launch of the banking union project. The conclusion formulates falsifiable expectations on which a theory of external influence in regional integration can be developed and tested.     

A comparison of the spatial distribution of innovative activities in China and the U.S.

In order to enhance the independent innovation capability and help China to become an “innovation-oriented country” this article compares the spatial distribution of innovative activities between China (representing a typical developing country) and the United States. We also provide some recommendations for China and other developing countries to optimize the spatial distribution of their innovative activities. Using invention patents as an indicator gathered from the websites of the CSIPO and the USPTO, this paper compares the spatial distribution of innovative activity in China and the U.S. by methods such as rank-frequency, concentration and classification. The results show that the invention patents have experienced rapid growth and significant fluctuation in recent years in China, while the United States has been relatively stable. The spatial diversity of patent distribution in China is more obvious than in the United States. There is a concentrated trend of innovative activities in both China and the United States from the inland areas to the coastal regions.     

Scale and efficiency measurement using a semiparametric stochastic frontier model: evidence from the U.S. commercial banks

In this paper, we use the local maximum likelihood (LML) method proposed by Kumbhakar et al. (J Econom, 2007) to estimate stochastic cost frontier models for a sample of 3,691 U.S. commercial banks. This method relaxes several deficiencies in the econometric estimation of frontier functions. In particular, we relax the assumption that all banks share the same production technology and provide bank-specific measures of returns to scale and cost inefficiency. The LML method is applied to estimate the cost frontiers in which a truncated normal distribution is used to model technical inefficiency. This formulation allows the cost frontier, inefficiency effects and heteroskedasticity in both noise and inefficiency components to be quite flexible.
