The Relevance of the Monetary Model for the Euro / USD Exchange Rate Determination: a Long Run Perspective

This study tries to fill a vacuum in the literature on the relevance of economic fundamentals for the Euro / USD exchange rate determination. We adopt the Monetary Model for the Exchange Rate Determination as our testing vehicle and investigate the relevance of various versions of this model over a long time horizon, spanning the period from the inception of Euro till the present time. We rely on cointegration analysis to conduct our empirical research and in accordance to the relevant literature we fail to accept most of the variants of this model. However, we get encouraging results from an expanded version of the Monetary Model where demand and productivity factors appear in the set of the exchange rate determinants.     

European common stochastic long-run trends

The paper examines convergence on the European level by using production functions which include capital and labor as factors of production. The methodology is based on principal-components analysis of common trends appropriate for heterogeneous panels. Using data for the 1960–1997 period and alternative specifications, it is found that convergence can be decisively rejected, although the number of common trends is relatively low (about four or five).     

Minority shareholders’ wealth effects and stock market development: Evidence from increase-in-ownership M&As

This paper examines, using a global M&A data set, the relationship between the target firm’s minority shareholders’ returns and a country’s stock market development in deals in which large shareholders increase their ownership stakes. For the purpose of this study, we use two measures of stock market development: (1) turnover over GDP, and (2) turnover over market capitalization. We provide evidence supporting the view that minority shareholders in target firms gain significantly more in countries with high stock market development than their counterparts in less-developed markets. Our results are robust to several firm and deal characteristics and provide evidence to policy makers that the degree of stock market development is a key determinant in improving minority shareholders’ welfare.     

A jump diffusion model for VIX volatility options and futures

Volatility indices are becoming increasingly popular as a measure of market uncertainty and as a new asset class for developing derivative instruments. Although jumps are widely considered as a salient feature of volatility, their implications for pricing volatility options and futures are not yet fully understood. This paper provides evidence indicating that the time series behaviour of the VIX index is well approximated by a mean reverting logarithmic diffusion with jumps. This process is capable of capturing stylized facts of VIX dynamics such as fast mean-reversion at higher levels, level effects of volatility and large upward movements during times of market stress. Based on the empirical results, we provide closed-form valuation models for European options written on the spot and forward VIX, respectively.     

Efficiency and productivity growth in the banking industry of Central and Eastern Europe

We employ the directional technology distance function and provide estimates of bank efficiency and productivity change across Central and Eastern European (CEE) countries and across banks with different ownership status for the period 1998–2003. Our results demonstrate the strong links of competition and concentration with bank efficiency. They also show that productivity for the whole region initially declined but has improved more recently with further progress on institutional and structural reforms. Input-biased technical change has been consistently positive throughout the entire period suggesting that the reforms have induced favorable changes in relative input prices and input mix. However we find evidence of diverging trends in productivity growth patterns across banking industries and that foreign banks outperform domestic private and state-owned banks both in terms of efficiency and productivity gains. Overall, we find that productivity change in CEE is driven by technological change rather than efficiency change.     

Back to basics: The Comanor–Wilson MES index revisited

The present article attempts to investigate the validity of the Comanor–Wilson Minimum Efficient Size (MES) measure. The basic assumption is that firms that have exhausted scale economies are in non-increasing returns to scale. The same firms are also assumed to have a size greater than MES estimated on sales (total turnover), employment or fixed assets. Data Envelopment Analysis (DEA) is used, on a sample of firms in three Greek manufacturing industries, to classify firms in operation according to increasing or non-increasing returns to scale. On the basis of the results of the DEA input oriented model, the MES measure correctly predicts over 85% of the cases. A probit model is applied to those cases that are not identically predicted by MES concerning returns to scale. Results indicate that technical efficiency, size and age are the factors that compel MES to yield the same prediction as the DEA approach.

Further insights on the relationship between SP500, VIX and volume: a new asymmetric causality test1

In the aim to explore the complex relationships between S&P500, VIX and volume we introduce a Granger causality test using the nonlinear statistic of Asymmetric Partial Transfer Entropy (APTE). Through a simulation exercise, it arises that the APTE offers precise information on the nature of the connectivity. Our empirical findings concretize the information flow that links volume, S&P500 and VIX, and merge the leverage effect and the asymmetric stock return-volume relationship into a unified framework of analysis. More specifically, when we condition on the tails, the detected causal channel provides empirical validation of the noise trading contribution to large swings in financial markets, because of the increase of trading volume and the subsequent worsening ability of market prices to adjust to new information.     

Inflation Transmission in Greater China

This paper examines inflation dynamics in Greater China. Using an asymmetric error correction model, we investigate how inflation in Hong Kong and Macao are related to inflation in Chinese Mainland. Our results based on data from July 1997 to December 2012 reveal that a long‐term equilibrium relation exists between inflation in Chinese Mainland and inflation in both Hong Kong and Macao, the two Special Administrative Regions of China. The degree of inflation pass‐through is higher for Macao than for Hong Kong. Moreover, we find no evidence of asymmetries in either Hong Kong and Macao's adjustment speeds towards long‐run equilibrium or in the short‐run pass‐through of accelerating or decelerating inflation in the Mainland. Collectively, our results show a close relationship among price dynamics of the three economies and call for a reconsideration of the exchange rate anchor in the Greater China Region.     

The risk of the sovereign debt default: the Eurozone crisis 2008–2013

We investigate the relationship of the market pricing of sovereign risk to default, through credit default swap (CDS) spreads for 16 Eurozone countries during 2008q1–2013q3. We take into account, through appropriate non-linear generalized method of moments (GMM) estimations the endogeneity problem. We focus on ‘fiscal space’ (DEBT or FISCAL), and the downgrade announcements (DOWN). We find DEBT (FISCAL) to have significant (insignificant) effects on the CDS concave function, as well as, DOWN in a linear one. It has also been confirmed significant pricing discrimination between South and West Euro Area Periphery (SWEAP) and the core Eurozone, highlighting asymmetries discovered either by the respective size of estimated DEBT coefficients or by the significant effects of DOWN that have only on CDS of SWEAP countries. The current account balance or the inflation rate, as well as, relevant interaction terms seem not to affect the spreads of the EMU. These findings, together with the estimated structural change on CDS pattern in early 2011, coinciding with significant either the DOWN in the pre-crisis period (2008–2010) or the DEBT in the post-crisis one (2011–2013) on the CDS, seem to be consistent with self-fulfilling crises literature and the inherent vulnerability of EMU, on other words, the ‘fragility hypothesis of the Eurozone’.
